LHP在模拟空间环境下的性能试验研究

PERFORMACE TEST OF LHP IN THE SIMULATING OUTER SPACE CONDITIONS

环路热管(LHP)是一种新型高性能热控元件,为将LHP应用到卫星等航天器的热控系统,必须检验其在空间 环境下的工作性能,为其在航天器上的具体应用提供依据和设计指导。本文重点介绍了LHP的低温真空试验及结果,结 果说明LHP的性能满足空间飞行器的热控技术指标要求。

Loop heat pipe (LHP) is a new thermal control apparatus of high efficiency. The working performance of LHP in the outer space should be tested before it applied in the spacecraft. So the simulative experiments should be done at the ground. In this paper, the experiment and its results of LHP at situations of vacuum and low temperature are introduced. The results indicated that the performances of LHP just meet the needs of spacecraft.
