Thermal Shock Test Chamber Ultimate Guide

Have you once wondered what a thermal shock test chamber is? Or, have you ever received complaints from your customer who said that your product didn’t work prematurely or had a short life?

How to say, such a phenomenon does not mean that the machine of your company is inferior in quality and standard.

The reason is that all products are bound to suffer the adverse impact brought by the environment in which they are applied. For example, when a lithium-ion battery is placed in an extremely cold condition, it will be impaired in terms of service life and storage capacity.

As a result, before bringing your product into the market, you should ensure the components of your product solid and endurable enough to withstand negative external factors.

Given such a situation, it is no doubt that the thermal shock test chamber will be a great aid.

So, today’s guide will take you through the significant aspects before you are resolved to buy a thermal shock test chamber or not.

This guide involves many aspects, ranging from the definition, application, specification, working principle and every other relevant information regarding The thermal Shock Test Chamber.

Now, let us get into the topic of today.

The Definition of Thermal Shock.

As exposed to the rapid exchange of drastic hot and cold, the inner part of the tested sample, such as the metal material, will experience great temperature difference in the shortest time, thus triggering a large shock thermal stress. This phenomenon is called thermal shock.

For example, in a building fire, the glass is heated rapidly. The ensuing great temperature differences make different parts of the glass expand by different amounts, which could result in a thermal shock. Experienced too much stress, the glass may lose its structural integrity and break into pieces finally.

What is Thermal Shock Resistance?

By definition, it refers to a tested product’s ability to withstand dramatic changes in temperature either during heating or cooling. For example, silicon nitride, a particularly heat-proof material, displays superior resistance to thermal shock, as tested by heating the material to 550℃ (1,022℉) and then rapidly cooling it by dropping it into water.

The Definition of Thermal Shock Equipment.

Thermal Shock Test Chamber, also known as thermal shock chamber, thermal shock equipment, or Environmental Stress Screen Test).

On the whole, thermal testing equipment models the influences of rapid transition between hot and cold zone to identify the thermal shock resistance power of your tested products.

Specifically speaking, the temperature shock chamber uses the cold storage method and the thermal alternating impact method to test the performance and parameters of the product after a sharp temperature change.

In other words, the thermal shock chamber is used to test the extent to which a material structure or composite material can withstand transiently in extremely high temperature and very low -temperature continuous environments.

The thermal Shock Test Chamber boasts a table area that carries a tested product and automatically transports a tested product between two separately controlled hot and cold zones.

Besides, it is convenient for you to observe the product during the transition process with a visible window installed in the thermal shock test chamber.

All these useful tools contribute to the realization of rapid temperature change for thermal shock.

Therefore, the thermal shock chamber is possible to test the chemical change or physical damage caused by the thermal expansion and contraction in the shortest time.

Purpose of Using a Thermal Shock Test Chamber.

When you want to buy a product reasonably, you need to have a general understanding of the application of this product.

To begin with, the thermal shock test chamber is designed to find defects in electrical assemblies, glass, rubber, plastics, metals, ceremic as well as other materials.

The purpose of the application at different stages of product development is different:

Engineering R&D (research and development) stage: you can discover the defects of components of a product with the temperature shock test chamber.

Improvement Stage: After finding the weakness in your product, you could make corresponding adjustments.

Simulated Experiment Stage: A good thermal shock chamber is critical for estimating potential success or failure of your product in reality. Because the external factors are complex and versatile. There is a high possibility that your products are exposed to the extreme cold and hot conditions simultaneously. To prevent such circumstances from happening, the importance of the thermal shock test chamber is evident.

Product Marketing Stage: you could add authentic and convictive data from the experiment to your product description.

Two Kinds of Thermal Shock Test Chamber

The thermal shock test chamber can be divided into 2 zone and 3 zone. The difference between 2 zone and 3 zone is the inner structure chamber and test method. 3 zone consists of Hot Zone, Cold Zone as well as Test Area. The tested sample is placed int the test area. 2 zone consists of Hot Zone, Cold Zone. The tested sample is placed into the basket.

Four Reasons for Using a Temperature Shock Test Chamber.

Highly Competitive Market:

With the swift development of the national economy, industries of various scale in China are rush in seizing opportunities to hold a  place in the market, i.e. plastic, metal as well as machine manufacturing industry.

Higher demands of customer:

The highly competitive the market , the faster the product supersedure.

Hence, there are more and more alternative choices for customers.

To stand out from your rival, you should intensify your efforts in the improvement of the quality of your product.

Ensuring Security of a Product:

Before bringing a product into the market, you should perfect the security of a product as many as possible. High security makes a good product and a high-class product brings a steady stream of passengers!

How to Choose the Thermal Shock Chamber?

At the time of purchase, they have their own requirements.

There are five aspects to be aware of when purchasing a thermal shock test chamber:

Impact Temperature

The impact temperature refers to the maximum temperature range that can be reached in the test area. Note that it is not the extreme temperature of the preheating and pre-cooling chambers;

Test Load

The test load directly affects how many test items can be placed. Generally speaking, the bigger the weight, the better;

Reset Time

Reversion time is the time it takes for the test item to switch from one temperature point to another. Our common specification is ≤5min. The smaller the time, the better;

Defrost Time

The longer the defrost interval, the better. It is very desirable to have a manufacturer who can do 1000 cycles of defrosting once. The shorter the defrost interval, the worse the airtightness of the device;

Sensor Placement

The sensor must be placed inside the test area. Some manufacturers place the sensor inside the air duct. Although it is only 10cm away from the test area, this energy difference is quite large. It does not accurately reflect the temperature change on the surface of the test article.

Last but not least, we are an environmental testing equipment and battery testing equipment company with 13 years of production and R&D experience.

Do You Know the Difference Between Three Types of Thermal Shock Chambers?

The thermal shock chamber is capable of simulating transient changes before high temperatures and low temperatures. It is generally used to determine if physical damage or performance degradation occurs when the equipment is subjected to drastic changes in ambient temperature. It is an essential test equipment for aviation, automotive, home appliances and scientific research. To assess and determine the parameters and performance of the complete machine and parts of testing instruments, machinery, electrical and electronic products after high and low thermal shock tests, suitable for aircraft flight exposure, air transport – desert exposure and ground or air – cold exposure.

Type of Thermal Shock Chambers

The structure of the thermal shock test chamber usually has the following three forms:

1. Three-box

Firstly, three-box of the thermal shock chamber. The three-box type consists of a test area, a high temperature area, a low temperature area, a cold cabinet, and a control cabinet. The three-box structure requires a large amount of cooling and heating.

2. Vertical Lifting

Secondly, vertical lift type of thermal shock chamber. The vertical lift type consists of a high temperature zone, a low temperature zone, a gondola, a cold cabinet and a control cabinet. Because It is through the conversion of the basket lift. Therefore it is avoiding the influence of the external environment. However, due to the vertical installation in the high and low temperature zones, if the test space is large, the overall height of the test box is relatively high. Therefore it will result in the operation is inconvenient. Thus, this method is generally suitable for small test chambers.

3. Horizontal Mobile

Thirdly, horizontal mobile type of thermal shock chamber. The horizontal mobile type is also composed of a high temperature zone, a low temperature zone, a moving basket, a cold cabinet and a control cabinet, and is installed horizontally in a high temperature zone and a low temperature zone, and is suitable for a large test box.

Among them, the vertical lifting type and the horizontal moving type are two-box type thermal shock test chambers.

Above all things, the choice of test method should be divided according to the specific situation. The most economical test equipment is selected on the basis of ensuring that the test standards are met.

The Characteristics of Thermal Shock Chamber

After understanding the differences of the three type of thermal shock chambers. Nextly, we mainly introduce the structural characteristics of vertical lift type thermal shock chamber.

The Cabinet of Thermal Shock Chamber

The cabinet is made of sprayed galvanized steel, which is beautiful and beautiful.

On the right is the control cabinet and the back is the refrigeration cabinet. There are two upper and lower doors in front, which are the high temperature test area and the low temperature test area.

The insulation material is polyurethane foam + ultra-fine glass wool, which has good thermal insulation properties. The bottom is a channel steel structure with good load-bearing performance.

In order to facilitate the movement and handling of the equipment, the base is equipped with casters and support feet.

The High Temperature Tank of Thermal Shock Chamber

The high temperature tank is located at the upper part of the tank. Because high temperatures can change the physical properties or dimensions of the materials used in the equipment. Therefore, the materials used in the high temperature tank must meet the requirements for use in high temperature environments. It is made of 1.0mm thick SUS#304 high & low temperature resistance stainless steel, which is beautiful and durable.

The front of the high temperature tank is a high temperature test area for use in high temperature tests or thermal shock tests.

Behind the high temperature tank is a circulating air duct with a circulating fan, impeller and heating device. The air is heated inside and the airflow in the front test zone is circulated for cyclic testing.

When the test sample is tested in the low temperature zone, the high temperature tank is in a heat storage state. And when the sample is moved from the low temperature zone, the high temperature test state can be restored in a short time.

The Low Temperature Tank of Thermal Shock Chamber

The low temperature tank is located at the lower part of the tank. Because low temperature has an adverse effect on almost all matrix materials. Therefore, the materials used in the low temperature tank must meet the requirements for use in low temperature environments. It is also composed of 1.0mm thick SUS#304 high & low temperature resistance stainless steel, which is beautiful and durable.

The front of the low temperature tank is a low temperature test area for use in low temperature test or low thermal shock test.

Behind the low temperature tank is a circulation duct, equipped with a circulating fan, an impeller, a heating device, an evaporator and a regenerator. After the air absorbs heat through the evaporator, it reaches the low temperature required by the test, and the airflow in the test area and the air duct are mixed into one, and the cycle test is performed.

When the test sample is tested in a high temperature zone, the low temperature tank is in a cold storage state. And when the sample is moved from the high temperature zone, the low temperature test state can be restored in a short time.

The Basket of Thermal Shock Chamber

There are two sample racks inside the basket.

The position of the sample holder is adjustable up and down. Besides, the bracket is composed of a SUS#304 stainless steel square tube.

The top and bottom are sealed plates, which act to seal the high temperature zone and the low temperature zone. The sealing part is provided with a silicone belt. Moreover, it does not deform under high and low thermal shock conditions, and the sealing performance is good.

The movement of the basket in the high and low temperature zones is driven by the cylinder. The cooperation of the cylinder, the wire rope and the roller is used to pull the basket to carry out the temperature impact test, thereby avoiding the disadvantages of the stroke of the conventional motor and the deformation of the casing.

When the basket moves to the high temperature test zone, the tension between the lower part of the gondola and the high and low temperature zone is pressed by the pulling force of the cylinder to serve as a sealing function.

When the basket moves to the low temperature test area, the separator between the upper part and the high and low temperature area is pressed by the self weight of the hanging basket to serve as a sealing function. The quality of the hanging basket seal directly affects the test performance.

Summary

As we konw, the use of thermal shock chamberis becoming more widespread. Choosing the right test equipment has a direct impact on the accuracy of the test. This article focuses on the vertical lifting type of thermal shock test chamber.

It has the ability to re-stabilize the test conditions within the test chamber within 5 minutes after the test piece is converted. It is worth mentioning that the conversion time of a sample from one studio to another is less than 10S, which is far beyond the requirements of the test standard.

Therefore, the vertical lifting type of two-box thermal test chamber has a fast conversion time and low test cost. It is the best choice for temperature test of small test pieces.

Safety Measures for Battery Testing

Battery testing is an important part of ensuring battery safety and reliability. Because the battery itself has certain risks (such as short circuit, leakage, leakage corrosion, etc.), the detection process also hides various safety risks.

In the inspection process, large-scale mechanical auxiliary equipment, high-current charging and discharging systems, and simulation experiments of extreme environmental conditions are often required. 

It is worthwhile to conduct in-depth research to ensure the safety of the battery testing laboratory and to ensure the personal safety of the laboratory personnel and the property safety of the equipment.

Classification of Battery Testing Items

First Classification

Battery testing items can be generally divided into four categories:

appearance inspection;

Appearance inspection includes appearance, polarity, dimensions and quality, ect.

Electrical performance testing;

Electrical performance testing includes room temperature discharge capacity, room temperature rate discharge capacity, charge retention and capacity recovery capability, storage and cycle life, etc.

Environmental adaptive performance testing

Environmental adaptability testing includes high and low temperature discharge capacity, high altitude simulation, constant temperature humidity, vibration resistance and salt spray, ect.

Safety testing

Safety performance tests include mechanical shock, drop, needling, crushing, collision, thermal shock, temperature cycling, external fire, water immersion, overcharge, overdischarge, external short circuit, and thermal abuse, ect.

Second Classification

The above test items can also be divided into three type tests are as follows:

Normal use tests

Normal use tests include high altitude simulation, temperature cycling, vibration and low rate charging.

Foreseeable misuse tests

Foreseeable misuse tests include external short circuit, heavy impact, mechanical shock, drop, forced discharge, abnormal charging, improper installation, overdischarge, overcharge, and high rate charging.

Abuse tests

The latter two types of tests are more dangerous than the normal use test.

Potential Danger of Battery Testing

Once the battery is used or is not properly stored, there is a danger of burning or explosion. In addition, there are certain security risks in the use of the testing equipment.

Fire Explosion

Battery fire explosion is usually caused by external factors such as needle sticking, extrusion, overcharging, high temperature and short circuit, causing internal short circuit or external short circuit of the battery, causing chemical reaction between the electrode material and the electrolyte.

Such as the decomposition of the solid electrolyte phase interface (SEI) membrane, the oxidation, reduction of the organic electrolyte, and the decomposition of the positive electrode. The oxygen generated by the decomposition of the positive electrode is further reacted with an organic electrolytic solution or the like.

If a large amount of heat generated by these reactions cannot be lost to the surrounding environment in time, it will inevitably lead to thermal runaway, which eventually leads to burning and explosion of the battery.

Leakage & Leaking

Lead-acid batteries use dilute sulfuric acid as the electrolyte and are corrosive. During the detection process, if the battery casing is broken and the electrolyte leaks, it will bring greater danger to personnel and equipment.

Lithium-ion batteries use organic electrolytes, such as gas emissions during the safety test, odor irritating and containing toxic substances.

Mechanical Danger

Tests such as mechanical shock, heavy impact, vibration, collision and drop are prone to loosening of the clamp, causing the battery to fly out and causing damage to personnel. In addition, the above-mentioned mechanical equipment operation itself has certain dangers.

Electrical Danger

The electrical property testing items such as capacity and cycle life require long-term continuous operation of the equipment and have certain safety hazards. In addition, during the battery connection process, there is a possibility that the battery is reversed or short-circuited.

Safety Protection Requirements and Measures

Personnel protection

Protection of personnel is a top priority. The inspector is in direct contact with the sample and equipment and is the implementer of the safety protection. It is also the object of safety protection. Take all possible measures to ensure the safety of personnel. Minimize contact, and don’t touch if you can’t touch it.

Personnel training should be strengthened to improve safety awareness and ability. It is necessary to equip the protective gear. It is strictly forbidden to wear protective gear to carry out dangerous or dangerous project inspection. The monitoring area and the test area should be properly separated, using remotely controlled equipment whenever possible.

Sample Protection

The protection of the sample is mainly during storage. Keep the environment dry and the temperature is stable and moderate. Insulate the electrodes to prevent accidental short circuits. Regular inspections should be conducted to find that hidden dangers are immediately excluded. It is necessary to properly classify the isolation to prevent mutual influence.

Equipment Protection

On the one hand, make sure that the device is functioning properly. On the other hand, it is necessary to prevent unexpected events from affecting the device. Inspection and maintenance should be strengthened. For charging and discharging testing equipment, dust should be removed regularly.

For mechanical equipment such as vibrating table and impact table, it is necessary to regularly remove dust and lubricate. Regularly check that the alarm function is normal. Safety equipment such as protective nets should be installed. For equipment that has been deactivated for a long time, it is necessary to cut off water and power off.

Environmental Protection

In the event of an abnormal condition in a closed test environment (eg environmental test chamber), the test shall be discontinued. After obtaining evidence (such as taking pictures of smoke and fire), it should be effectively extinguished and exhausted through a dedicated exhaust passage of the tank. The test room should be installed with smoke, equipped with fire-fighting facilities such as fire extinguishers, sandboxes and fire hydrants.

The discarded batteries after the evidence collection shall be disposed of in a harmless manner according to the instructions of the sample supplier and the relevant specifications of the laboratory, or submitted to a professional organization for reasonable disposal according to relevant regulations and procedures.

Summary

The security protection of the laboratory can be started from both management and hardware facilities. With the continuous development of battery detection technology, the continuous improvement of laboratory management regulations and the continuous improvement of the safety of the battery itself, the safety factor of the battery testing laboratory will continue to increase.

The safety of the battery test equipment hardware facilities is the top priority of laboratory safety. Our environmental test chamber and battery test equipment are equipped with good safety facilities. For example: Automatic explosion-proof pressure relief device, explosion-proof chain, tri-color light alarm device, remote control, smoke exhaust device, fire extinguishing device, etc.

What is an Environmental Test Chamber and How Does It Work ?

With the rapid development of the modern industrial technology,electrical, electronic products have been widely used. At the same time, the environmental conditions are becoming more and more complicated. Only by properly regulating the environmental protection measures of the products can the products be protected from damage during storage and transportation, and safe and reliable during use. Therefore, electrical and electronic products used in artificially simulated environmental tests are an essential part of ensuring high quality.

In this article, we’ll explain what a test chamber is and how does an environmental chamber work.

What is Environmental Test Chamber?

Before we learning the environmental test chambers, we should know what the Environmental Test is, and where it can be used. This test is not difficult, the principle of it is widely used in our daily life, like refrigerator, which can change temperature to help food keep away from the deterioration.

Every product made from industry will suffer from the damage of environment. The Environmental Test can help you to find the point which the product will be damaged at. For measuring the availability of your products the Environmental Test Chambers accelerate the changing of environment, or add extreme conditions that the natural absolutely can not reach.

Therefore, with the help of the Environmental Test Chamber you can know the information about how long your products can be used in nature environment, and the peak which your products can reach in an extreme environment will be find.

Some conditions that the Environmental Test Chamber can take for you:

1.Temperature variations: With temperature variations, you can find the thermal section that your products can bear.

2.Humidity: As one of the most effective factors in environment, humidity bothers products all the time. With the Environmental Test Chamber, we can easily change the humidity for your products bearing.

3.Salt spray: Also called salt fog test, salt spray test is one of the most popular corrosion test methods.

4.UV degradation: Many of products are always exposed to the sun, so it is necessary for your products to have a UV degradation test which can help you to find the bearing section of that.

5.Vacuum: The vacuum condition for some special products.

6.Stimulate weather: For some products that are mainly effected by weather factors .

Most Environmental Test Chambers can change the conditions we have listed, according to that, we can classified the Chambers.

The representative test chambers include:

Thermal shock test chamber

salt spray test chamber

ultraviolet aging test chamber

xenon lamp aging test chamber

ozone aging test chamber

High and low temperature test chamber

Constant temperature and humidity test chamber

Temperature humidity vibration combined test chamber

The Environmental Test Chamber is always used in these test:

We utilize different test chambers for different intentions, for environmental tests, there are four main tests that the chamber usually be used.

Steady State Tests: The chamber controls the temperature and humidity may other factors in a certain scope and hold the temperature in a certain time. You can use this type of tests to measure the service life of your products, or to test the stability in a certain environment for long time. The result of this test will be more accurate.

Thermal Cycling Tests: In this test, the chamber provides two extreme environments for your products, and shift between them in a period of time. It is a slow process. During this test, the variation of your products should be visible.

Thermal Shock Tests: This test just like its name, the chamber takes an extreme environment for your products quickly. Then you will find the peak bearing of them to against the extreme environment.

Slat Spray Test: Also called salt fog test, it is widely known as one of the corrosion test. Using this test you can find the availability of your products when they are exposed to the real environment.

The thermal cycling tests are similar with the thermal shock tests, but they are very different things. Thermal cycling test is a slower process than thermal shock test. Though both of them provide two environments for products, but thermal cycling test is a slower test than thermal shock test. With controlling certain temperature and humidity, thermal cycling test would take an accurate result for manufacturers. On the other hand, the thermal shock test will take data about the durability that your products in a switching two extreme environments.

The size of Environmental Test Chamber: Ranging from the Walk-in or Drive-in Chamber to the small size chamber that can put on a placement like big desk or somewhere like that.

How Does an Environmental Chamber Work

The temperature and humidity test chamber is suitable for testing electronic, electrical appliances, food, automobiles, rubber, plastic glue, metal and other products. It can meet different environmental conditions such as high temperature and high humidity, high temperature and low humidity, low temperature and high humidity, high temperature and low temperature, and will provide you with the basis for forecasting and improving product quality and reliability.

They mainly use temperature and refrigeration systems. The main function is cooling, generally using advanced refrigerator control technology to stabilize the test space. Secondly, the test chamber also needs to use the dehumidification system to solve the problem of humidity.

(1) High low temperature test chambers are suitable for high temperature and low temperature reliability tests of industrial products. For the parts and materials of related products such as electric and electronic, automobile and motorcycle, aerospace, shipbuilding, colleges and universities, research institutes, and other high-temperature and low-temperature (alternating) cyclical changes, test their performance indicators.

(2)The constant temperature humidity test chamber is also called constant temperature humidity test machine. It is used to test various materials for heat resistance, cold resistance, dry resistance and moisture resistance. It is suitable for electronics, electrical appliances, communication, Instruments, vehicles, plastic products, metals, food, chemicals, building materials.

(3)The salt spray corrosion test chamber can evaluate the salt spray corrosion resistance of the material and its protective layer, and the process quality of similar protective layers. At the same time, it can evaluate the resistance of some products to salt spray corrosion. The product is suitable for parts and electronics. Original, protective coatings for metallic materials and salt spray corrosion tests for industrial products.

(4)The thermal shock test chamber usually uses two extreme environments, put the product in and shift the two environments quickly. With this test, the resistance to switching between extreme environments that products have is visible.

Why You Need Environmental Test Chambers?

Industrial products are subject to various temperature, humidity, climate and external conditions during manufacturing, handling, storage and application. These factors may cause physical, mechanical, and even chemical changes in the product. This will make the product lose its effect, reduce the value or create danger!

Had you heard a explosion of a cell phone? Or met a situation that a product can not work even when you utilize it at first time? All these problems were caused by the lack of the quality of your products. So it is important that make a test to measure the durability of your products!

Environmental Test Chambers simulate common or external environments for your products to measure their durability. With ECT Chambers you can change the temperature or humidity,even create the climate you want, and find the problems that hide in glamorous surface of your product.

Find them! And solve them! Your products will become more prefect!

On the other hand, with Environmental Test Chambers, the data you got from the test is valuable for your research & development.

There are some reasons why you need Environmental Test Chambers:

There are different climate between your aim markets and producing area: Different areas have different climate that made by different temperature and humidity. Your products may have a well resistance of dry, but difficult exist in wet weather. Thinking of that, you need an Environmental Test Chamber for your products.

With good quality your products are more reliable than your competitors: With Environmental Test Chambers, you can measure your products once and once again, find the problem and solve it, which can promote the quality of your products.

Promote the safety of your products: Customers prefer durable, crushing-resistant products, the former can make the product more valuable, but the last come from a safety considering.

Industrial products are subject to various temperature, humidity, climate and external conditions during manufacturing, handling, storage and application. These factors may cause physical, mechanical, and even chemical changes in the product. This will make the product lose its effect, reduce the value or create danger!

Some products must be test before putting them into markets.

As we all known, a car without weather tests can not be sold. The weather test can help manufacturers find somewhere that the part of cars not assembled well. With many times of weather testing, finally promote the safety of the car. Only pass this test, the product can be sold.
