Overview
JIANGKAI NBC-LC-150 (-40 ℃) Thermal Shock Test Chamber is mainly used to test the resistance of materials to extremely high temperature or extremely low temperature. It simulates the situation that the product is not continuously in high temperature or low temperature, and can complete the test in the shortest time. The equipment is used to test the tolerance of the material structure or composite in a continuous environment of extremely high temperature and extremely low temperature in an instant, and to detect the chemical changes or physical damage caused by thermal expansion and contraction of the sample. The product is divided into two-box and three-box type, and the PID system is used for full digital automatic control, which is easy to operate.

Principle
The equipment realizes temperature impact through the structural design of high temperature heat storage area, low temperature cold storage area and product test area. The forced ventilated equilibrate temperature regulation method (BTC) is adopted. In the case of continuous operation of the refrigeration system, the Control system controls the output of the heater through PID automatic calculation according to the set temperature point to achieve dynamic equilibrate. The refrigeration system adopts binary cascade Water-Cooled refrigeration, which includes two refrigeration cycles of high temperature and low temperature. Energy is transferred through evaporative condenser, and the heat energy in the studio is transferred through the two-stage refrigeration system to achieve cooling. The refrigeration cycle adopts reverse carrot cycle, which achieves the purpose of cooling through compression, condensation, expansion and evaporation.
