FIELD: communication, TV broadcasting and information retransmission satellites and their heat control systems.
SUBSTANCE: on-board device with concentrated heat source is placed inside inner cavity of heat-insulated closed liquid-radiation heat exchanger and excessive heat from this device is removed to circulating water supply line. Inlet and outlet of liquid cavity of said heat exchanger are connected with delivery and discharge lines of circulating water supply system. Connecting pipe lines are provided with drainage and cutoff valves mounted before inlet and outlet of said liquid cavity below heat exchanger level. Parameters of pipe line running from delivery main of circulating water supply system to inlet of said liquid cavity are selected according to special condition. Box-shaped liquid-radiation heat exchanger consists of two sections with double wall: base and hood; their liquid cavities are communicated with atmosphere through drainage holes provided with shut-off members.
EFFECT: facilitated procedure; reduction of expenses.
