Thermal shock chambers are used to test the durability of various materials and components by subjecting them to extreme temperature changes. These chambers can be a valuable tool for manufacturers, but they are not without their challenges. In this article, we will discuss some of the frequently occurring problems with thermal shock chambers and potential solutions.

Problem #1: Condensation
One of the most common issues with thermal shock chambers is the buildup of condensation during testing. When a sample is moved from a hot chamber to a cold chamber, the rapid temperature change can cause moisture to form on the surface of the sample. This can lead to inaccurate test results or even damage to the sample.

Solution: To prevent condensation, it is important to ensure that the thermal shock chamber is properly sealed and that the humidity level is controlled. This can be achieved by using a dehumidifier or by adding a desiccant to the chamber. It is also important to minimize the amount of time that the sample spends in the temperature transition zone, as this is when condensation is most likely to occur.

Problem #2: Sample breakage

Another common issue with thermal shock chambers is sample breakage. When a sample is subjected to rapid temperature changes, it can become brittle and prone to cracking or breaking. This can be especially problematic for delicate or complex samples.

Solution: To prevent sample breakage, it is important to choose an appropriate test method and temperature ramp rate. It is also important to carefully select the sample size and shape to ensure that it can withstand the thermal shock testing. In some cases, it may be necessary to use support fixtures or padding to protect the sample from mechanical stress.
