摘　　要：本文主要针对我国载人空间站高温材料科学实验系统的任务需求,完成了系统热控方案的设计,包括液冷板布置、电机驱动机构和真空室热设计。基于系统三维几何模型,应用Ther ma l Desktop软件建立了系统仿真模型,确定了实验系统在最恶劣工况时的边界条件。仿真结果表明,真空室外壁、控制电机、丝杠、滑块及导轨的最高温度分别为36.3℃、44.3℃、47.3℃、49.6℃和46.1℃,均低于温度限制值,系统热控性能满足设计要求。According to the task requirements of the high temperature materials science experiment system of China's manned space station,this paper completes the design of the thermal control scheme of the system,including the layout of liquid cooling plate,motor driving mechanism and thermal design of vacuum chamber.Based on the three-dimensional geometric model of the system,the system simulation model is established by using thermal desktop software,and the boundary conditions of the experimental system under the worst working conditions are determined.The simulation results show that the maximum temperatures of the outer wall of the vacuum chamber,the control motor,the lead screw,the sliding block and the guide rail are 36.3℃,44.3℃,47.3℃,49.6℃and 46.1℃respectively,which are lower than the temperature limit,and the thermal control performance of the system meets the design requirements.
