SPACECRAFT TEMPERATURE CONTROL SYSTEM Russian patent published in 2019 - IPC B64G1/50 

FIELD: astronautics.

SUBSTANCE: invention relates to space engineering, particularly, to temperature control systems. Spacecraft thermal control system comprises two duplicated identical fluid circuits. In each fluid circuit there is a temperature regulator of heat carrier flow of direct action. It has one inlet and two outlets, the first outlet is connected to the liquid path at the radiator inlet, and the second outlet is connected to the liquid circuit at the radiator outlet. In the liquid circuit between the first outlet of the temperature regulator and the inlet to the radiator the first additional valve is installed. Section of the liquid circuit located between the first output of the temperature regulator and the inlet of the first additional valve is connected through the second additional valve to the liquid circuit connecting the second output of the temperature regulator to the outlet of the radiator.

EFFECT: improved weight characteristics and improved operability is achieved.
