The rapid temperature change test chamber is a testing equipment that achieves rapid temperature conversion in an instant. It exhibits excellent performance in the quality assessment and identification of temperature resistance in harsh environments for information electronic instruments, materials, electricians, electronic products, and various electronic components.
The rapid temperature change principle of the rapid temperature change test chamber;
A、 The changes in temperature are mainly manifested in high temperature, low temperature, and temperature cycle control. The high temperature part is easy to control, mainly by controlling the heating of the heating tube. The speed of temperature heating mainly depends on the number of heating tubes and heating power, and the high temperature is independently controlled.
B、 The control of low temperature is the core of the entire rapid temperature change test chamber. In order to achieve rapid cooling and temperature reduction, the compressor is generally a German valley wheel semi enclosed compressor unit (7.5 horsepower × 2), combined with electrical control components such as Italian CAS, Swiss ALFALAVAL, Danish DANFOSS, American RANCO, Japanese Eginomiya, etc. R404A is used for high temperature stage, and R23 environmentally friendly refrigerant is used for low temperature stage. The connection between the two stages is made using a Swedish Alfa Laval plate exchanger, and the evaporative condenser serves as both a high-temperature evaporator and a low-temperature condenser.
C、 Circulating system: In order to efficiently and evenly distribute hot and cold air inside the inner tank, multiple long axis fans are used for circulating cooling or heating, quickly achieving temperature changes or maintaining a constant temperature. The fans are imported from France, with high control accuracy and long service life.
