The rapid temperature change test chamber is suitable for the adaptability test of the whole machine and parts of electronic and electrical products under the condition of rapid temperature change or gradual change. The temperature acceleration technique is used to change the external environmental stress, so that the product produces thermal stress and strain.
6 Important Parts of Rapid Temperature Change Test Chamber
1. Refrigeration system
The LIB refrigeration system uses mechanical refrigeration compressors and environmentally friendly refrigerants. Since the temperature during the test must reach -50°C, single-stage refrigeration is difficult to meet the requirements. The refrigeration method of the rapid temperature change test chamber generally uses a bipolar refrigeration compressor.
2. Heating system
The heating system of the rapid temperature change test chamber is mainly composed of high-power resistance wires. Meet the rapid temperature rise of the fast-changing test chamber.

Refrigeration System
Air Circulation System
3. Control system
The control adopts programmable controller, multiple languages can be selected, programming and fixed value can be set, fully automatic operation, can be connected to computer, wifi, USB, network port
4. Humidity system
The humidification method of the fast temperature change test chamber generally adopts the steam humidification method.
5. Sensor system
The sensors of the rapid temperature change test chamber are mainly temperature and humidity sensors. The most widely used temperature sensors are wet and dry bulbs and electromagnetic sensors.
6. Air circulation system
The air circulation system is generally completed by a centrifugal fan. In addition, the sample rack of the LIB test chamber is designed for punching, and the air circulation is uniform.
