摘　　要：介绍了太阳能电池驱动的半导体制冷冰箱系统的基本结构，建立了太阳能电池驱动的半导体冰箱的理论模型，并对系统性能进行了数值模拟，分析了太阳辐射强度和环境风速的变化对太阳能半导体制冷系统性能的影响。研究表明针对设计的太阳能半导体制冷系统，在某一太阳辐射强度下，系统的制冷量输出最大，并且在辐射强度200～1000W/m^2时，制冷系数随着太阳辐射强度的减小而减小。在给定的工况下，环境风速增加使得系统工作电流朝靠近最佳工作电流数值方向增加。The basic structure of a thermoelectric refrigerator driven by solar cells was described. A theoretical model of a solar thermoelectric refrigerator was set up and numerical simulation of the system was performed. The effect of different solar insolation rate and velocity of air on solar thermoelectric refrigeration system was analyzed. The results indicate that there is an optimum solar insolation rate, at which the system can achieve maximum cooling production. When the solar insolation rate is about 200 - 1000 W/m^2, COP for the specified system decreases with the decrease of insolation rate. Under given conditions, the system working current increases in the direction of the optimum system working current with the increase of air velocity.
