The high and low temperature test chamber is used to test the degree of tolerance of material structure or composite material under the extreme high temperature and extremely low temperature continuous environment, so as to test the chemical change or physical injury caused by thermal expansion and cold contraction.
The applicable objects of the high and low temperature test box include metal, plastic, rubber, electronics and other materials, which can be used as the basis or reference for the improvement of its products. The high and low temperature test chamber is suitable for aerospace products, information and electronic instruments, materials, electricians, electronic products, and all kinds of electronic gas parts in high and low temperature or hot and humid environment, and test its performance indicators.
The most important part of the functional components of the high and low temperature test box is heating and cooling.
1. High temperature test box heating system:
1. High speed infrared heating (2KW * 2) electric heater with far infrared nickel alloy
2. The high temperature completely independent system does not affect the low temperature test, the high temperature test and the alternating
3, temperature control output power by microcomputer calculation, to high precision and high efficiency of electricity efficiency.
Two. High temperature test box refrigeration system:
1, compressor: all closed French Taikang 1.5HP x 2 x 1 groups
2, refrigeration mode: cascade refrigeration
3, condensing mode: forced air cooling cooling
4, refrigerant: R404A, R23 (environment-friendly)
5, the pipeline system were tested. 48H pressure ventilation leakage
6. The heating and cooling system is completely independent
7, internal spiral copper tube
8, slope evaporator
9. Dry filter, cold medium flow window, repair valve, oil separator, solenoid valve and liquid storage cylinder are all imported original parts
10, dehumidification system: using evaporator coil dew point temperature laminar contact dehumidification method
11, when cooling, start R404A, R23, only start R404A when dehumidification (energy saving and reducing consumption)
