| The cold and hot impact test chamber simulates the change of high temperature and low temperature in a short period of time. It is used to test the material structure or composite material, and the degree of endurance under the continuous environment of extremely high temperature and low temperature in an instant. It is mainly used in metal, plastic, rubber, electronic and other material industries. High and low temperature test chamber simulates the environment of high temperature, low temperature and high and low temperature alternation. It is mainly used for industrial products, such as electronic and electrical products, automobile motorcycles, aerospace, marine weapons, colleges and universities and other industries to test the quality of products. Although these two kinds of environmental testing equipment are used to test the performance of products at high and low temperature, their temperature change time is different. The temperature of high and low temperature test chamber is increased by 3 degrees per minute and decreased by 0.7-1.2 degrees per minute. However, the change of high and low temperature in cold and hot shock test only needs 5 minutes, and the time conversion is fast. The test conditions are more brutal. Cold and hot impact test chamber can realize the function of high and low temperature chamber, but high and low temperature chamber can not replace high and low temperature chamber. The cost of the test box is very different. Taikang brand totally enclosed compressor is selected for the high and low temperature test box. If it is a small equipment with temperature above - 40 at any time, single-stage compression refrigeration can be selected; the German bizel compressor is used for the cold and hot impact test box, with high power and fast refrigeration speed.
