FIELD: space engineering; temperature control systems of geostationary communication and TV broadcasting satellites. ^ SUBSTANCE: proposed system includes closed loop with liquid heat-transfer agent and liquid subloop of service system module with radiator, heat-removal unit, volume compensator, electric pumping unit and heat-transfer agent flow regulator. Said loop includes also liquid subloop of payload module whose liquid passage runs through thermostatically controllable panels. Outer surfaces of skins of panels are provided with heat-liberating units and panels proper are cellular in form with liquid passages built in them. Base panel is located in plane perpendicular to longitudinal axis of spacecraft. Side panels are mounted on base panel perpendicularly relative to it in parallel planes perpendicular to North-South axis of spacecraft. Central panel is mounted in between side panels perpendicularly relative to them. Built-in liquid passages are made in form of pipe lines with shelves in zones of mounting of heat-liberating units. Pipe lines are bonded to inner surfaces of skins on side of shelves. ^ EFFECT: reduction of mass of system. ^ 2 cl, 8 dwg |
