304 / 316 Stainless Steel Two Boxes Of Basket Type High And Low Tempterature Impacee Test Chamber
Cold and hot impact test box, also known as high and low temperature impact test box, is a necessary test equipment in the metal, plastics, rubber, electronics and other materials industries.It is used to test the endurance of the material structure or composite material in the continuous environment of extreme high temperature and low temperature in an instant, and it can detect the chemical changes or physical injuries caused by the thermal expansion and contraction of the sample in the shortest time.
The cold and hot impact test box is divided into three boxes and two boxes according to the test requirements and test standards. The difference lies in the different test methods and internal structures.
1. To simulate test environment with various altitude environments .
2. It is especially important for defense and aerospace applications where pressure and vacuum conditions are even more intense
3. Application fields: Include Aviation, aerospace, communications, electronics, electrical appliances etc.
4. Test Purpose: to guarantee the maximum quality and reliability while products or material might encounter at various altitude levels.

Working principle of refrigeration:
Reverse carole cycle is used in both high and low refrigeration cycles, which is composed of two isothermal processes and two adiabatic processes.The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the exhaust temperature is increased by the energy consumed. After that, the refrigerant is heated by the condenser isothermal and the surrounding medium to transfer the heat to the surrounding medium.After the refrigerant through the valve adiabatic expansion of work, at this time the refrigerant temperature reduced.At last, the refrigerant absorbs heat from the object with higher temperature through the evaporator.This cycle is repeated to achieve the goal of cooling.
