The invention provides a thermal control system and method for a near-earth orbit gravitational wave detection and verification satellite. The system comprises: a first-stage thermal control module which comprises a plurality of cabin plates, wherein a load is surrounded at the center and is closed to form a load cabin, and a thermal insulation gasket and/or a multilayer thermal insulation assembly are/is arranged inside and/or outside the load cabin to make the load isolated from other heat sources; a second-stage thermal control module which comprises an automatic temperature control unit, detects the temperature of the load cabin, sends the temperature of the load cabin to a thermal control main processor, and controls an automatic temperature control unit to adjust the temperature by adopting a PID algorithm according to the temperature of the load cabin in order to make the load cabin form a constant-temperature cage type heating area during load work; and a third-stage thermal control module which comprises a compensation module fixed on the load, a thermal insulation assembly wrapping the load and the compensation module, and a temperature measurement unit, wherein the temperature measurement unit detects the temperature of the load and sends the temperature of the load to the thermal control main processor, and the PID algorithm is adopted to control the compensation module to adjust the temperature according to the temperature of the load in order to make the temperature of the load kept uniform everywhere during working.

    本发明提供一种用于近地轨道引力波探测验证卫星的热控系统及方法,一级热控模块包括多块舱板,将载荷包围在中心并封闭,形成载荷舱;在载荷舱的内部和/或外部布置隔热垫片和/或多层隔热组件,使载荷与其他热源隔绝;二级热控模块包括自动控温单元,检测载荷舱的温度,并将载荷舱的温度发送至热控总处理器,采用PID算法根据载荷舱的温度,控制自动控温单元进行调温,以使载荷舱在载荷工作时形成恒温笼式加热区域;三级热控模块包括固定于载荷上的补偿模块、包裹载荷及补偿模块的隔热组件、以及测温单元,测温单元检测载荷温度,并将载荷温度发送至热控总处理器,采用PID算法根据载荷的温度,控制补偿模块进行调温,以使载荷在工作时各处温度保持均匀。
