摘　　要：全面考虑半导体致冷器件冷热端的瞬时温度特性,对研究半导体致冷的精确控制有重要意义。根据半导体致冷器件的工作原理,结合实际工作情况,推导出了半导体致冷器件任意时刻的表面温度计算公式,从而可以得到任意时刻的致冷量,所用方法和结果可用以指导对半导体致冷实时温度控制系统的设计。The instantaneous temperature characteristic of thermoelectric cooler cool side and hot side is very important for accurate temperature control. Formula model to calculate the instantaneous value of thermoelectric cooler surface temperature is deduced according to the thermoelectric cooler operating principle and practical working situation. Then the instantaneous refrigerating output can also be calculated. The method and resuh may be useful for the design of the real-time temperature control system in thermoelectric cooling field.
