文章对落月轨道的外热流进行了分析，比较了几种热控设计方案的优缺点，探讨了热控优化设计的原则，认为在落月轨道上激光设备的热控设计应首选热容热控方案，对于在其他飞行阶段有长期开机需求的情况再考虑散热面方案或热电致冷方案。“嫦娥三号”月面探测器激光高度计采用了热容热控设计，该设备热控设计能够满足不同阶段温度指标要求并且与热分析结果相一致，热控设计方案正确、优化原则合理可行。

The Land-On-Moon Orbit has obvious transient characteristics. The optimization principle of the thermal control design plan for the laser equipment used on the Land-On-Moon Orbit is discussed through the thermal analysis. The best thermal control design plan is to use the heat capacity of the equipment, unless the laser equipment is required to operate for a long time. An application case is the thermal control design plan for the laser altimeter used on the Chang’e-3, which uses the heat capacity of the equipment. The remote measurement data show that the temperature restriction of the equipment is realized. The thermal control design method is shown to be practical.
