1、Can work continuously without any refrigerant, there is no pollution source or rotating parts, no rotation effect, no sliding part. A solid piece without vibration, noise, possess long life and easy installation 2、Semiconductor refrigeration film possess two functions of both cooling and heating 3、A current‑transducer type chip. High‑accuracy temperature control can be realized through the control of the input current. It is easy to realize remote control, program control, and computer control to form an automatic control system when coupled with temperature detection and control means 4、The cooling and heating time is very fast, the thermal inertia of the semiconductor cooling fin is very small, the cooling fin will reach the maximum temperature difference in less than one minute when the hot end has good heat dissipation and the cold end is empty 5、Semiconductor refrigeration fins are generally used for power generation in the middle and low temperature areas. Reverse use of semiconductor refrigeration fins is thermoelectric power generation
