A solid piece without vibration, noise, possess long life and easy installation 2Semiconductor refrigeration fins support both cooling and heating. The cooling efficiency is generally 55?60%, but the heating efficiency is very high and always greater than 1. Therefore, one piece can replace separate refrigeration system and heating system 3The semiconductor refrigeration chip is a current?transducer type chip. Through the control of the input current, high?accuracy temperature control can be realized. Coupled with temperature detection and control means, easily realize remote control, program control, and computer control to form an automatic control system 4Thermal 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 maximum temperature difference in less than one minute 5Semiconductor refrigeration fins are suitable for power generation in the middle and low temperature areas. The reverse use of semiconductor refrigeration fins is thermoelectric power generation 6The power of a single refrigeration component pair of a semiconductor refrigeration chip is very small, but when combined into a stack and the same type of stack is used in series and parallel to form a refrigeration system, the power can be very large, the cooling power can be several Milliwatts to tens of thousands of watts 7The temperature resistance of the semi?conductor refrigeration sheet is 80 degrees on the hot side at normal temperature, 150 degrees on the medium temperature hot side, and 200 degrees on the high temperature hot side; Temperature difference between the hot end and the cold end can reach 67 degrees at the first level and 80 degrees at the second level. 90 degrees at the third level, 107 degrees at the fourth level1 x Thermoelectric Cooler Module
