Overview
The three box impact box is used to test the degree to which composite materials and material structures can withstand continuous high and low temperature environments in an instant, that is, to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest possible time. Suitable objects include metal, plastic, rubber, electricity and other materials, which can be used as a basis or reference for product improvement.

1refrigeration system
1The refrigeration compressor adopts two branded semi enclosed compressors to form a cascade refrigeration system. This fully enclosed compressor has the characteristics of large refrigeration capacity, low energy consumption, low noise, and high conversion rate; The refrigeration system also adoptsPLC control, energy regulation cold end output method, surpasses the traditional cold and hot balance control method, meets requirements through PID regulation, greatly reduces user usage costs, extends equipment service life, and improves equipment economy; Beneficial for reducing equipment noise and improving the working environment of the laboratory.
2Cooling method: water cooling;
3Condensation evaporator: using a heat exchanger, which has a small volume, high temperature and pressure resistance, and a high heat transfer coefficient;
4Refrigerant: Environmental ProtectionR404A、R23；
Refrigeration auxiliary components: In order to ensure the safe and reliable operation of the refrigeration system, the main refrigeration accessories such as expansion valves, solenoid valves, filters, pressure controllers, globe valves, oil pressure controllers, oil separators, etc. are all branded products.
