overview
Cold and heat shock Test Chamber Alias: temperature shock Test Chamber, high-low temperature shock Test Chamber, temperature cycle Test Chamber, etc.
It mainly tests the chemical changes or physical damage caused by thermal expansion and contraction of products at extreme high-low temperature moments.
Cooling methods include air cooling and water cooling. The advantage of air cooling is that it occupies a small area, but the disadvantage is that the cooling speed is slow; the advantage of water cooling is that the cooling speed is fast, but the disadvantage is that it occupies a large area.
The difference between the thermal shock Test Chamber and the constant temperature and humidity Test Chamber
1. Constant temperature and humidity can be used as humidity; cold and heat shock cannot be used as humidity.
2. The constant temperature and humidity change from low temperature to high temperature for a long time; the high-low temperature switching time of two boxes of cold punching is 15 seconds, and the stabilization time is 3 minutes, and the high-low temperature switching and stabilization time of three boxes are both 5 minutes.
3. The price of constant temperature and humidity is cheap; the price of cold and heat shock is expensive.
4. There is only one test box for constant temperature and humidity, and there are test boxes for cold and heat shock, cold storage box and heat storage box.
