摘　　要：对多级热电制冷器进行了理论分析。在三种不同工况下,运用ANSYS模拟四种不同类型热电制冷器的制冷温度,并搭建实验台进行了实验研究。模拟结果表明,热电制冷器热电对之间的距离对其制冷温度有影响,设计热电制冷器时,应对热电对距离进行优化设计。实验结果表明,实验用热电制冷器最佳工作电压为12V,热电制冷器制冷温度受外界环境影响非常大,选择合适的绝热材料对制冷器制冷温度有重要影响。实验结果还表明,热电制冷器输入电流和功率随热端温度升高而减小,制冷温度和最大制冷温差随热端温度升高而增大。Theoretical analysis of multistage thermoelectric cooler was done in this paper. The cooling temperatures of four different multistage thermoelectric coolers were obtained in three different conditions by ANSYS simulation software. A test bench was conducted to verify the simulation. The simulation results showed that the cooling temperature of thermoelectric cooler was influenced by the distance of the thermoelectric couple, and the distance of thermoelectric couple should be considered in designing the cooler. The test results showed that the optimal operating voltage of the thermoelectric cooler was equal to 12V. The refrigeration temperature was extremely influenced by the external environment. The insulation material had an important impact on the performance of multistage thermoelectric cooler. The test results also showed that the input current and power would decrease with the hot end temperature increasing; the largest temperature difference and cooling temperature would increase with the hot end temperature increasing.
