摘　　要：影响热电制冷器性能的主要因素有热电材料、冷热端强化散热方式等,利用数值模拟技术对冷热端不同散热方式:双自然对流、冷端自然对流热端强制对流以及冷端与人体接触热端强制对流的工况下,热电偶内部通过的电流对冷端温度的影响进行分析。对比有限元模拟结果与实验结果,从中找出与理论计算产生误差的原因及实验存在的问题,得出有限元模拟技术在热端制冷器温度控制方面的可预测性。Effects of thermoelectric cooler performance are the main factors of thermoelectric material, hot and cold end heat dissipation mode of strengthening. By using numerical simulation technology to the hot and cold junction heat dissipation mode of two different： natural convection, natural convection of cold end, the hot end and the cold end of the forced convection is contancted with human body heat end forced convection condition , and analying the effect thermocouple of the cold end temperature when the current is passing through. Comparison of finite element simulation results and experimental results, and finding out the cause of the error and theoretical calculation and experimental problems, that finite element simulation technology in the hot end of refrigerator temperature control predictabil- ity.
