The thermal stress rapid change test chamber system can be divided into two parts: a high-temperature chamber (preheating zone) and a low-temperature chamber (precooling zone). Rapid thermal shock testing is achieved by controlling a movable basket (test sample placement area) to quickly move to either the low-temperature or high-temperature chamber. During the test, the test sample moves along with the movable basket. Compared to high and low temperature (two chambers) thermal shock test chambers, the thermal stress rapid change test chamber has a faster temperature transition speed (stress change time less than 10 seconds), providing more stringent testing for the test samples.
