摘　　要：粒子激发X射线谱仪(APXS)安装在月面巡视器外部,利用巡视器的机动性和机械臂的灵活性,可以对月面有研究价值的月岩及月壤进行有针对性的探测.由于裸露在巡视器外部,月球复杂外热流会对APXS产生较大影响.鉴于此,需对APXS进行合理的热设计,以保证APXS的探测器和电子学器件工作在允许的温度范围内.提出了APXS的热设计方案,据此对APXS进行热仿真计算,计算结果得到了相应热平衡试验的较好验证.The APXS （Alpha Parlicle X-ray Spectrometer） is installed on the outside of the Lunar Rover, so that the lunar rocks and soil can be studied by the mobility of the Rover and flexibility of the robotic arm. Because of being exposed outside the rover, APXS will have great impact by the complex outer heat flux. In view of this, a reasonable thermal design is necessary for APXS to ensure that the APXS detector am l electronic devices operate within the temperature range of its allowance. In this paper, the thermal control designs of APXS and the thermal simulation calculation results based on its thermal control designs are summarized. And the calculation results have been validated by corresponding thermal balance tests.
