HEAT-TRANSFERRING DEVICE OF A SATELLITE Russian patent published in 2007 - IPC B64G1/50 

FIELD: thermal control systems, primarily for telecommunication satellites.

SUBSTANCE: claimed device contains closed two-phased contour, filled with low boiling point heat carrier (ammonia). Contour includes evaporator, hydro-accumulator and capacitor, attached to case of radiator, all interconnected by connecting pipelines. Evaporator has thermal connection to two oppositely positioned thermostatted surfaces. In the body of evaporator, capillary pump is installed, to external surface of which contact surfaces of evaporator body shelves are closely adjacent. Evaporator and capacitor are built into cell panel of satellite with two thermostatted cases and made in form of profiled pipeline of aluminum alloy, each with two shelves. Shelves are attached (in case of evaporator - glued) to cases of panel. Internal surface of profiled pipeline in zones, positioned in front of shelves, has shelves with longitudinal and transverse grooves. In other zones recesses are made. Capillary pump has bimetallic flange, which is soldered to external surface of pump and welded to ends of aforementioned profile and connecting pipelines.

EFFECT: reduced mass of device (by 7-15%) in comparison to analogical technical solutions, reduced hazard of penetration of mains of evaporator and radiator by meteorites under conditions of operation.
