1、Semiconductor cooler, can both refrigerate and heat. The cooling efficiency is generally 55‑60%, but the heating efficiency is very high and always greater than Therefore, using a single piece can replace separate refrigeration and heating systems. 2、It does not need any refrigerant, it can work continuously, there is no pollution source, no rotating parts, no rotation effect, no sliding parts, no vibration or noise during work, and easy installation. 3、Semiconductor cool plate is a current‑transducer type chip. Through the control of input current, high‑precision temperature control can be realized. 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, fast cooling and heating time. When the hot end has good heat dissipation and the cold end is empty, the cooling plate can up to the maximum temperature difference in less than one minute. 5、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. 6、Power of a single refrigeration component pair is very small, but it is combined into a electric pile. If the same type of electric pile is used in series and parallel to form a refrigeration system, the power can be very large, so the cooling power can be up to several milliwatts. The range of ten thousand watts. 7、Temperature resistance is 80℃ for normal temperature hot side, 150℃ for medium temperature hot side, and 200℃ for high temperature hot side; the temperature difference between the hot side and the cold side can up to 67℃ in the first stage, and 80℃ in the second stage. The third level reaches 90℃, and the fourth level reaches 107℃.
