摘　　要：针对立方星因尺寸小、质量轻、电量少、热容量小和热流密度大等特点带来的热设计难题,该文提出一种完全被动热控制设计方法。分析了TW-1B立方星热控输入条件,提出被动热控制的具体措施,并建立了热分析模型进行仿真计算。结果表明,立方星各部件温度计算结果均在要求的工作温度范围之内,说明被动热控制设计可以满足立方星对热控系统的要求。提出应采用地面热环境试验来验证热分析计算的准确性,并根据试验数据对热分析模型进行优化,改进热设计,以确保卫星在轨寿命。Considering the design difficulty of thermal control caused by the small dimension,the light weight,the less electricity,the small heat capacity and the large heat flow density of the cubesat,the passive thermal control method is proposed here. Through the detailed analysis of thermal control design input,concrete measures of the passive thermal control are presented. The thermal model is set up and simulated. The result shows that temperature calculation values are in the range of the requirements of work temperature and the design of passive thermal control measures can satisfy the task of the thermal control system. It is advised that the ground thermal environment experiments should be used to verify the accuvacy of thermal analysis calculation,optimize the thermal analysis model,and improve thermal design to ensure the life of cubesat in orbit.
