摘　　要：轨道外热流是影响空间引力波探测卫星的重要因素之一。总结了日心轨道引力波探测卫星和地心轨道引力波探测卫星的β角和外热流变化,分析了外热流的变化特征。引力波卫星采用以被动热控为主,辅以主动热控的热设计原则,对整星和关键载荷(如空间望远镜)进行热设计,同时采取柔性支撑结构解决结构热变形问题,保证子结构尺寸的稳定性,最后介绍了空间引力波探测卫星热仿真分析。The external heat flux is one of the important factors affecting the space gravitational wave detection satellite.In this paper,theβangle and external heat flux of the heliocentric and geocentric gravitational wave detection satellites are summarized,and the variation characteristics of the external heat flow are analyzed.The gravitational wave satellite adopts the thermal design principle of passive thermal control,supplemented by active thermal control.The thermal design of the whole satellite and the key payload(e.g.space telescope)is carried out.At the same time,flexible support structure is adopted to solve the thermal deformation problem of the structure to ensure the stability of the substructure.Finally,the thermal simulation of gravitational wave detection satellite is introduced.
