The approach of heat pipes’ implementation into passive radiative cooling system is considered for optical sensors (CCD), operating on the temperature level of 180…240 K in unsteady regime. Heat pipes have shown themselves as effective heat transfer element used for heat moving from sensor to radiator on distance up to 0.5 m and as heat redistribution element, being integrated into low temperature radiator. In order to avoid the negative influence of the external heat fluxes the system design with a set of thermally coupled radiators, interconnected with heat pipes (conventional and thermodiodes) is proposed. This design allows to keep the low temperature level of CCD at spacecraft maneuvers and to widen the operation range of solar constant
