[0002] Currently, there are various types of test chambers used for product performance testing, the most common being thermal shock test chambers and high and low temperature test chambers.

[0003] Specifically, thermal shock test chambers are mainly used to simulate extremely rapid temperature changes (such as -55℃ to 85℃ within a few seconds) to test the material's tolerance to drastic temperature changes (such as thermal expansion and contraction, solder joint cracking, etc.). High and low temperature test chambers are mainly used to simulate slow, stable temperature changes (such as 1-10℃ / min) to test the performance of products under long-term high and low temperature environments (such as aging, functional stability).

For example, thermal shock test chambers can only perform thermal shock tests, while high and low temperature test chambers can only perform high and low temperature tests. This makes it difficult to better meet users' needs for thermal shock and high / low temperature testing, or for more complex testing modes. Therefore, there is an urgent need to provide a high / low temperature and thermal shock test chamber with high structural integration, capable of meeting users' needs for single or combined high / low temperature and thermal shock testing.
