1. There are no sliding parts, it is a solid piece, there is no vibration, noise, long life, and easy installation;
2. It does not need any refrigerant, it can work continuously, there is no pollution source, no rotating parts, and no rotation is easy;
3. The semiconductor refrigeration film has two functions, which can be used for cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is very high. Therefore, a single piece can replace the separate heating system and the cooling system;
4. The semiconductor refrigeration chip is a current-transducer type chip. Through the control of the input current, high-precision temperature control can be realized. Coupled with temperature detection and control methods, it is easy to realize remote control, program control, and computer control, which is convenient to form automatic control system;
5. The thermal inertia of the semiconductor cooling fin is very small, and the cooling and heating time is very fast. When the hot end has good heat dissipation and the cold end is empty, the cooling fin can reach the rated temperature difference in less than one minute;
6. The reverse use of semiconductor refrigeration fins is thermoelectric power generation. Semiconductor refrigeration fins are generally suitable for power generation in the middle and low temperature areas;
7. The power of a single refrigeration element of the semiconductor refrigeration film is very small, but it is combined into a stack, and the same type of stack is used in a series or parallel method to form a refrigeration system, the power can be made very large, so the cooling power can be made In the range of a few milliwatts to tens of thousands of watts;
8. The temperature difference range of the semiconductor refrigeration sheet can be realized from a positive temperature of 90°C to a negative temperature of 130°C.
