摘要:

针对深空探测同位素电源的发展需求，设计了一套基于热管散热平台的热光伏系统，采用分离型热管实现了热光伏系统的热控要求，并实验验证了热光伏系统的热电转换性能。研究了加热功率、充液量对热管启动特性、壁面温度的影响，分析了辐射器温度、电池温度对系统电输出特性的影响，并对系统的转换效率进行了评估，结果表明：采用热管散热器可有效将半导体电池温度控制于25℃以下，在辐射器温度为1 173℃时，系统热电转换效率达到12.1%。

Abstract:

Aiming at the power requirements of the deep-space exploration, a set of the thermo-photovoltaic system with heat pipe is designed in this article. The separate gravity heat pipe is employed to realize the thermal control requirement, and the thermo-electric conversion capability of the TPV system is confirmed. The effect of the thermal power, amount of the working fluid on the startup performance, wall temperature is investigated. Also the influence of the temperature of the emitter and the cell on the system electrical output performance is analyzed. The results indicate that the heat pipe can control the cell temperature below 25℃.While the emitter temperature reaches 1 173℃, the thermal-electric conversion efficiency reaches 12.1%.
