When purchasing a hot and cold impact test chamber, you must first understand the experimental results that your product wants, and the importance of the product. Once again, Sichuan Hongzhan Technology is a national high-tech enterprise. The hot and cold shock test chamber that meets the national standard is divided into two compartments. The difference between the sedan and the sedan, and whether your site can be water-cooled, whether your test environment is up to standard, our factory provides you with free door-to-door viewing. There are no fewer than dozens of factors affecting the use and life of engineering products (equipment) in the thermal shock test chamber. Engineers engaged in the study of the conditions of engineering products have summarized the conditions of nature and the conditions of human activities. It is a series of test standards and specifications for guiding the conditions and reliability tests of engineering products. Therefore, the main basis for our selection of condition and reliability test equipment is engineering products and test standards.

1. Cooling and thermal shock test chamber refrigeration system and compressor: In order to ensure the test cooling rate and low temperature requirements, the test chamber adopts a binary double-layer environmentally friendly refrigerant refrigeration system consisting of a German COPEANDBAN semi-hermetic compressor. The stacking system comprises a high pressure refrigeration cycle and a low pressure refrigeration cycle, the connection vessel being a function of the evaporative condenser. The evaporator for reducing the pressure cycle is used only as a condenser for the high pressure cycle. The design and application of the energy-conditioning technology of the refrigeration system is an effective treatment method to ensure the effective adjustment of the energy consumption and cooling capacity of the refrigeration system under the normal operation of the refrigeration unit, so that the operation cost of the refrigeration system Drop to a more economical attitude.
2. Cold and hot shock test chamber refrigeration working principle: high and low refrigeration cycle evenly adopts reverse card cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: high pressure of refrigerant compressor adiabatic compressor The exhaust gas is consumed to increase the temperature of the exhaust gas, and then the refrigerant is heat-exchanged with the surrounding medium through the condenser to transfer heat to the surrounding medium. After the refrigerant shut-off valve adiabatic expansion work, this is the temperature of the refrigerant is reduced, and this cycle is repeated to reach the purpose of lowering the temperature.
3. Refrigerant: It adopts R404A (low pressure circulation) and R23 (high pressure circulation) environmentally friendly refrigerant produced by DUPONT Company of the United States.
4. Cooling method: air or water cooling.
5. Refrigeration aids: The main refrigeration accessories and control devices use imported originals.
The thermal shock test chamber is used to test the degree of tolerance of materials and material structures under transient conditions of high temperature and extremely low temperature, that is, to test the chemical changes caused by thermal expansion and contraction in the shortest time. And physical damage. The objects used include plastics, metals, rubber, electronics, etc., which can be used as a basis or reference for product improvement.
