What are the hot and cold shock test box samples?

Hot and cold impact test chambers are used in electronics, auto parts, metals, chemical materials, plastics and other industries to test the repeated resistance to high and low temperatures of various materials, and to test the physical damage or chemical changes caused by the product's thermal expansion and contraction. To confirm the quality of products, from the sophisticated IC to the heavy machinery components, it needs its approval. However, nothing can be tested with the hot and cold shock test box. What are the prohibited test samples?

In order to ensure the cooling rate and the minimum temperature of the test chamber, this test chamber adopts a binary cascade refrigeration system consisting of imported German semi-hermetic compressors (required to install circulating cooling with an average cooling capacity of 10 tons per hour. Water tower, provided by the user). The cascade refrigeration system includes a high-temperature heating cycle and a low-temperature refrigeration cycle. The connection vessel is an evaporative condenser. The evaporative condenser is also used to transfer energy. The heat energy in the working room is transferred through the two-stage cooling system to achieve cooling. the goal of. The design of the refrigeration system uses energy-adjustment technology. An effective treatment method can ensure that the energy consumption and cooling capacity of the refrigeration system can be effectively regulated under the normal operation of the refrigeration unit, so that the operating cost of the refrigeration system can be maintained. And the failure rate dropped to a more economical state.

Refrigeration Working Principles The high and low refrigeration cycles use an inverse Cascade cycle consisting of two isothermal processes and two adiabatic processes. The process is as follows: The refrigerant is adiabatically compressed by the compressor to a higher pressure, and the power is consumed so that the temperature of the exhaust gas rises. After that, the refrigerant exchanges heat with the surrounding medium via the condenser isothermally to transfer heat to the surrounding medium. After the refrigerant through the valve adiabatic expansion work, when the refrigerant temperature decreases. Finally, the refrigerant absorbs heat from the higher temperature object isothermally through the evaporator, so that the temperature of the cooled object is reduced. This cycle is repeated to achieve cooling.
