摘　　要：{针对环境温度对热电散热器性能影响很大的特点,对采用热电制冷系统冷却的户外电子设备散热器进行了数值模拟研究,并得出了用于设计户外电子设备热电散热器的冷热端最优热导分配比.模拟结果表明：当室外月平均气温为0~40℃时,散热器最优热导分配比为0.42~0.54;系统散热器的总热导值从30W·m/K增至50W·m/K,单片热电制冷片所承担的冷负荷从20W增至30W的情况对散热器的最优热导分配比取值影响很小.Based on the feature that outdoor environment has a significant impact on the performance of the heat sink of the thermoelectric cooling system,a numerical simulation study was carried out on the heat sink of outdoor electronic devices,which adopt the thermoelectric cooling system.And the optimum thermal conductance ratio of the heat sink was obtained for the design of the heat sink of the outdoor electronic device.The simulation results indicate that the optimum conductance ratio is 0.42~0.54 when the outdoor monthly average temperature ranges from 0℃to 40℃.Besides,the total thermal conductance of the heat sink increases from 30 to 50 W·m/K,and the cooling load undertaken by single TEC is from 20 to 30 W,both of which has little influence on the optimal results.
