The cold and hot shock test chamber is also called the cold and hot shock machine. It is suitable for the safety performance test of electronic components, providing reliability test, product screening test, etc. At the same time, through this equipment test, the reliability of the product can be improved and the quality control of the product can be carried out.
The refrigeration cycle of the cold and hot impact test chamber adopts the reverse Carro cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatic compressed to a higher pressure by the compressor, and the work is consumed to increase the exhaust temperature. Then the refrigerant is isothermal exchanged with the surrounding medium through the condenser, and the heat is transferred to the surrounding medium. After the refrigerant expands adiabatically through the valve to do work, the temperature of the refrigerant decreases. Finally, the refrigerant absorbs heat from the higher temperature object isothermal through the evaporator to reduce the temperature of the cooled object. The cycle is repeated for cooling purposes.
