The hot and cold shock test chamber is mainly used for temperature shock test.
The degree that can be endured in a continuous environment of extremely high temperature and extremely low temperature in an instant, can be converted from a high temperature of 150 ℃ to a low temperature of -65 ℃ within 10s-15s, and the recovery time can be completed within 5 minutes.
The high and low temperature impact test chamber is a test equipment for high temperature and low temperature, but it cannot meet the test requirements from high temperature to low temperature in a short time, because it takes a long time to complete the switch from high temperature 150℃ to low temperature -65℃. Obviously, the test conditions are achieved by gradually cooling down. For example, we need to complete the high temperature from room temperature to 150°C within 35 minutes, but after the high temperature test, we need to reach the environmental condition of -65 ℃ within 3 minutes.
The functional difference between the hot and cold shock test chamber (high and low temperature shock test chamber) and the high and low temperature shock test chamber lies in the temperature change rate of the two. The structure conversion time is slightly different. The conversion time of the three-box cold and heat shock test box is less than 3s, and the conversion time of the two-box cold and heat shock test box is less than 5s, but no matter which structure, the recovery time should be less than or equal to 5min. The high and low temperature test box is an experiment that can simulate high temperature constant temperature conditions, low temperature constant temperature conditions and high and low temperature conditions.
The structural difference between the thermal shock test chamber and the high and low temperature test chamber is that the thermal shock test chamber is generally a three-box or two-box structure, while the structure of the high and low temperature test chamber is a single box.
