SPACE VEHICLE TEMPERATURE CONTROL SYSTEM Russian patent published in 2009 - IPC B64G1/50 

FIELD: transportation.

SUBSTANCE: said utility invention relates to the space engineering, in particular to the telecommunication satellite instrument temperature control system. The system comprises a circuit with a bi-phase coolant. The circuit comprises a hydraulic pump, manifolds of panels, on which instruments are installed, radiator panel manifolds, and a battery connected between one another by main lines. The battery housing has zones for gas (coolant vapours) and the liquid phase of the coolant. The latter zone communicates with the main line running to the hydraulic pump inlet. The said circuit includes a capillary pump with an electric heater installed on the outer surface of its shell. The vapour cavity of the capillary pump communicates with the gas zone in the battery housing, and its liquid cavity is connected to the main line running to the hydraulic pump inlet. The connection is made upstream of the connection point of the pipeline running from the battery housing and the said line.

EFFECT: decreased temperature control system weight and provision of narrower range of operating temperature of vehicle instruments in conditions of thermal loads changing in wide range.
