摘　　要：为解决汽车露天停放,车内温度过高问题。利用太阳能发电技术和半导体制冷技术,设计出太阳能半导体制冷装置。完成了半导体制冷系统实验平台搭建,以及主要元件半导体制冷片、太阳能电池板和太阳能控制的选型。对装置制冷空间的负荷进行了估算并进行了性能测试。实验表明:随着制冷片电压的增加,其制冷量逐渐增加,增加幅度逐渐减小,制冷系数则呈现先增加后减小的趋势。制冷装置在风冷散热时,热端风扇最佳电压为10V,制冷片的实际制冷系数最大且制冷量较大;工作电压为6-14 V时,半导体制冷片制冷量大,但实际制冷系数偏小。In order to solve the problem of high temperature in the car parking.Using solar power generation technology and semiconductor refrigeration technology,a solar semiconductor refrigeration device is designed.The experimental platform of semiconductor refrigeration system was set up,and the main components of semiconductor refrigeration film,Solar Panel and solar control were selected.The load of the refrigeration space was estimated and the performance was tested.The experimental results show that with the increase of the plate voltage,the refrigerating capacity increases gradually,the increasing range decreases gradually,and the refrigerating coefficient increases first and then decreases.When the cooling device is cooled by air,the best voltage of the hot-side fan is 10V.and the actual cooling coefficient of the refrigerating plate is the largest and the refrigerating capacity is larger than that of the semiconductor refrigerating plate when the working voltage is 6~14V,but the actual cooling coefficient is small.
