FIELD: heating.
SUBSTANCE: invention relates to thermal control board research and service equipment of spacecraft: artificial satellites, interplanetary stations, etc. System includes at least two temperature-controlled panels (TCP) with built-in heat pipes and at least two radiators. Each TCP is connected to one of radiators by means of controlled loop heat pipes (LHP). Evaporators of said LHP are installed on TCP, and condensers are built into radiators. There is a backup radiator connected to TCP by additional controlled LHP. Evaporators and condensers of said LHP are similarly connected to TCP and backup radiator. Steam pipes of additional LHP are fitted with valves to close or open said steam pipes.
EFFECT: technical result is improvement of reliability of thermal control system, reduced weight and dimensions.
