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!

High Cost-worthing Performance:

With high cost-worthing performance, our thermal shock test chamber is for sale at factory price. Hence, it is the first choice for you among other products of the same kind.

What is the Thermal Shock Test Standard? 

  • IEC68-2-1 Environmental testing -Part 2: Test methods-Tests A: Cold.
  • IEC68-2-2 Environmental testing for electric and electronic products Test methods -Tests B: Dry Heat.
  • MIL-STD-810D Environmental test methods and engineering guidelines.


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.
