Failure Mechanisms of Cooling Loss in Thermal Shock Test Chambers ——A Systematic Analysis Based on the Reverse Carnot Cycle

Thermal shock test chambers are indispensable in reliability qualification for electronics, aerospace, and automotive industries. Once the “no-cooling” fault occurs, the test sequence is immediately interrupted and secondary damage to the specimen may follow.

Sharing: Some Product Features of Thermal Shock Test Chambers

Although thermal shock test chambers also detect the weather resistance of test specimens by simulating different natural temperatures, this equipment differs from other temperature and humidity series test equipment. What are the unique features of such products? Let me introduce some features of this product.

Are You Maintaining Your Constant Temperature and Humidity Test Chamber Correctly?

If a constant temperature and humidity test chamber malfunctions due to improper operation or lack of maintenance, it will not only affect the progress of work but also incur costs much higher than those of regular maintenance.
