摘要： In one embodiment, a thermal radiative system for an earth orbiting satellite including a plurality of faces intermittently exposed to maximum solar illumination comprises a thermal radiator is mounted on a face for discharging heat from a thermal load to deep space. A heat conductor extends between the thermal load and the thermal radiator. Thermal switches are operable for connecting the thermal load to the thermal radiator for cooling when the temperature of the thermal load is above a predetermined level and for disconnecting the thermal load from the thermal radiator when the temperature of the thermal load falls below the predetermined level. A shield including phase change management (PCM) material is thermally connected to the thermal load for drawing heat away therefrom. In another embodiment, first and second thermal radiators are mounted on first and second faces, respectively, of the satellite for discharging heat from the thermal load and the thermal load is sequentially connected to the first and second thermal radiators to achieve optimum discharge of heat from the thermal load. To this end, the thermal load is thermally connected to the first radiator so long as the first radiator is exothermic and thermally disconnected from the first radiator when the first radiator becomes endothermic and is thermally connected to the second radiator so long as the second radiator is exothermic and thermally disconnected from the second radiator when the second radiator becomes endothermic.
