摘　　要：为研究太阳能半导体制冷系统热端采用不同散热方式时诸多因素对其制冷性能的影响,设计并搭建了实验平台。研究结果表明:在热端分别采用强迫风冷、水冷和热管三种散热方式下,热端风扇电压、制冷片辅助装置、循环水量、热管风扇电压、制冷片电压均存在使系统制冷性能最优的相应配置;当系统选用4片TEC1-12708制冷片且电压为12V,热端采用热管散热且其风扇电压为10V时,可满足119. 92W的制冷设计需求,且系统制冷系数可达0. 47。In order to study the influence of various factors on the cooling performance of solar semiconductor refrigeration system with different cooling modes, an experimental platform of this system was built. The results show that, when three kind modes of forced air cooling, watereooling and heat pipe cooling are respectively applied to cool the heat end, there are the best corresponding configurations such as voltage of the hot end fan, refrigeration auxiliary device, amount of the recycled water, voltage of the hot pipe fan and chilling plate. And these can make the cooling performance of the system optimal. The system can meet the refrigeration design requirements of 119.92W, and the system cooling coefficient is up to 0.47 when it uses four TEC1 - 12708 cooling plate and the voltage is 12V, heat pipe is used to cool the heat end and the fan voltage is 10V.
