摘　　要：为克服由于月球热环境的特殊性给热控设计带来的困难,尤其是卫星度过月食的极端状态条件,首次采用了舱外两舱热耦合热管、相变材料热管技术,为最终嫦娥一号卫星热控状态满足总体的技术要求发挥了关键作用。由于两舱热耦合技术的采用,两舱的热能量得到了相互补偿,因此减少了整星散热面,减少了热补偿功率需求,提高了月食结束时蓄电池的温度,使热控技术方案成为相对优化的方案。文章对热管技术在嫦娥一号卫星热控设计中的应用进行了总结,并给出了热分析及热平衡。In order to overcome the difficulty of thermal design induced by the lunar thermal environment,especially the extreme cold conditions during lunar eclipse, CE-1 satellite adopted heat pipe between panels and phase-change heat pipe. These heat pipe technologies played an important role in satellite project. As a result of the application of the thermal couple,heat of two panel can compensate each other. So the area of radiator of the satellite was reduced, the heat power demand cut down, the batteries temperature increased during eclipse, and the thermal design im- proved. Finally, this paper introduced the heat pipe technology applications in thermal control of lunar satellite, and presented some test or analysis results about heat pipe applications.
