Abstract

Abstract: Capillary pump loop(CPL)heat pipe has high heat transfer capability and temperature control ability.Heat can transfer across a long distance under a minimal temperature difference,without mechanical pumping.CPLs have been applied in many areas,including the thermal management of advanced space platforms and the cooling of electrical and electronic devices.In this study,a CPL system with eight evaporators was designed and fabricated for the thermal management.Experimental investigations were conducted on operating characteristics of the CPL in the anti-gravity arrangement. Based on the experimental measurements,the heat transfer characteristics of the multi-evaporator CPL were analyzed and discussed.The results show that the multi-evaporator CPL demonstrates good thermal responses and reliable working behavior,applicable to a variety of operating conditions.

Key words: capillary pump loop, anti-gravity, multi-evaporator, startup, thermal resistance analysis

摘要： 毛细泵回路(CPL)热管具有传热能力高、控温能力强等优点,可以实现小温差、长距离、无附加动力的热量传输,在航天器热控系统和电子器件冷却方面具有广泛的应用。利用自行设计的多蒸发器CPL系统,通过反重力布置时多蒸发器CPL的启动运行实验,分析了多蒸发器CPL的启动工作特性和稳定运行时的热管热阻。结果表明,多蒸发器CPL在反重力布置时具有良好的启动特性,多蒸发器共同工作时,运行稳定、温度分布均匀,可适应多种工况的要求。
