摘要/Abstract

摘要： 对阿尔法磁谱仪（AMS-02）低温冷却器环路热管的启动特性进行了数值模拟研究。结果表明热负荷高利于环路热管的启动。某些结构或者装配的差别产生的接触热阻造成两侧并联的环路热管热量分配不均，从而低负荷时导致一侧环路热管无法启动。主副毛细芯的结构有利于建立热管启动的过热度。

Abstract: Two loop heat pipes (LHP) with parallel connection are used to cool the condenser of Alpha Magnetic Spectrometer 02(AMS-02).However, a series of factors lead to only one of LHPs primarily setting up and the other one failing to set up. The article established three-dimensional model of the LHP evaporator, used FLUENT to simulate its start-up temperature field. It is concluded that higher heat load facilitate start-up. Contact thermal resistance produced by structure or equipment difference can cause failure start-up. Finally, wick with primary and second wicks is better for start-up than wick of one single material.

Key words: Alpha Magnetic Spectrometer 02(AMS-02), loop heat pipes, start-up characteristic, simulation, porous media, heat transfer
