SPACECRAFT TEMPERATURE CONTROL SYSTEM Russian patent published in 2000 - IPC

Abstract RU 2151723 C1

FIELD: space engineering; temperature control systems of communication satellites. SUBSTANCE: according to invention, liquid passages of temperature control system used for cooling the instruments and service systems and liquid passage of radiator consist of two parallel branches. Each branch has one inlet and one outlet. Outlet of instrument cooling passage are connected with respective inlets of radiator; first and second outlets of radiator are connected respectively with second and first inlets of instrument cooling passage via branches of service system cooling passage. Electric pumping unit with volume compensator is fitted in one of lines running to liquid instrument cooling passage. Radiating areas of parts of liquid passages of radiator branches are directly proportional to total thermal loads in instrument cooling branches and service system cooling branches. Electric heater of radiator liquid passage has total power satisfying the special conditions of thermal balance. EFFECT: reduced power requirements; enhanced operational reliability; increased of service life of temperature control system to 15.5 years. 3 cl, 2 dwg
