摘　　要：为减少热控制分系统的能源需求,减轻整星的能源负担,分别从精准热补偿、错峰热补偿、精细化热设计、整星资源统筹等几个角度提出了热控能源优化设计方案。提出了一种预埋式管路辐射器,并将其上的低温补偿加热器实施在管路上后进行一体预埋,形成一体化辐射器。采用光照阴影分时段的差别式阈值控制,利用整星热容降低阴影期补偿功耗需求等方法。经仿真分析及试验验证,以上几种方式均能够有效减少热控制系统的热补偿功耗需求。In order to reduce the energy demand of thermal control subsystem and alleviate the energy burden of the entire system,optimization design methods for thermal control are proposed from several perspectives,including precise thermal compensation,staggered thermal compensation,refined thermal design,and integrated resource coordination.A preprocessing pipeline radiator is proposed,and the low-temperature compensation heater on it is also integrated and embedded to form an integrated radiator.The heater adopts differential control of light and shadow time division,and utilizes the entire star heat capacity to reduce power consumption of shadow period.Through simulation analysis and experimental verification,the above methods can effectively reduce the thermal compensation power consumption requirements of the thermal control system.
