摘　　要：太阳能在能源利用与开发中有巨大发展前景,其与半导体制冷的结合对特殊环境下制冷具有重要意义。通过实验对比分析了不同热端散热方式下TEC1-12708制冷片的制冷量和制冷系数,获得了该制冷片的最佳散热方式及其稳定运行电压范围。藉此,通过对半导体制冷系统分析,建立数学传热模型,利用数学软件MATLAB对其进行了求解,将模拟与实验结果进行了对比。研究结果表明:相较于热管与风冷散热,水冷散热为最佳散热方式;8 V^12 V电压为实验最佳电压范围;模拟与实验结果比较,误差在合理范围,验证了数学传热模型的合理性。Solar energy has a great prospect in energy utilization and development, and its combination with semiconductor refrigeration is of great significance to refrigeration in special environment.By comparing and analyzing the cooling capacity and coefficient of the TEC1-12708 refrigerator under different heat-end heat-dissipation modes, the optimal heat-dissipation mode and the stable operating voltage range were obtained.Based on the analysis of semiconductor refrigeration system, a mathematical heat transfer model was established and solved by mathematical software MATLAB.The simulation and experimental results were compared.The results show that water cooling is the best heat dissipation compared with heat pipe and air cooling mode;8 V^12 V voltage is the best voltage range of the experiment;Compared with the experimental results, the error is in a reasonable range, which verifies the rationality of the mathematical heat transfer model.
