1. A solid piece without vibration, noise, possess long life and easy installation. Can work continuously does not need any refrigerant, there is no pollution source or rotating parts, no rotation effect, no sliding part
2. Semiconductor refrigeration film have two functions, both cooling and heating
3. The product is a current‑transducer type chip. High‑accuracy temperature control can be realized through the control of the input current. Coupled with temperature detection and control means, it is easy to realize remote control, program control, and computer control to form an automatic control system
4. The thermal inertia is very small, and the cooling and heating time is very fast, the cooling fin will the maximum temperature difference in less than one minute when the hot end has good heat dissipation and the cold end is empty
5. Reverse use of semiconductor refrigeration fins is thermoelectric power generation. Semiconductor refrigeration fins are usually suitable for power generation in the middle and low temperature areas
