What's the working principle of thermal shock test chamber?

Thermal shock test chamber is used to test the bearing extent of the material structures and composite material in an instant and continuous high temperature and extremely low temperature environment , that is in the shortest time to test its thermal expansion and contraction caused by chemical change or physical harm. Application objects, including metal, plastic, rubber, electronics and other materials can be used as a basis to improve their products or reference.

Let's take a look at what is the working principle of thermal shock test chamber?

Working principle of three zone thermal shock test chamber: Test products are placed in test box, it adopt upper,middle and lower box structure,the upper box is high temperature box,the middle box is test box,the lower box is low temperature box.The upper high temperature box and lower low temperature box are able to set the test temperature and extreme temperature condition. When use low temperature chamber test,the low temperature door be opened with test chamber to test working space,and process low temperature test.Switch to the high temperature test,the door of low temperature box door is closed ,the high temperature box and test box to be a new test working space,the mechanical action of switch can be completed in less than 1s,and the temperature can be fast stable.During the whole test processing,the sample is not moved at all and no need operator intervention.

Working principle of three zone thermal shock test chamber: Test products are placed in the basket,the motor driver basket movement to complete the high and low temperature switching temperature transformation,the test samples are moving with the basket. Two box type equivalent put sample into the high temperature zone and low temperature zone. So, with the real three zone thermal shock test chamber is not same and get the “thermal impact” result will not be same.
