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). The contour includes capacitor with input and output, evaporators, having common input and common output, and hydro-accumulator, installed closely to common input of evaporators, all interconnected by pipelines. Hydro-accumulator has body, which has mutually opposite input and output, connected respectively to output of capacitor and to common input of evaporators, mesh fuse, positioned inside the body near its walls, and electric heater. Capacitor is attached to covers of radiator. Evaporators, in body of which capillary pumps are installed, are connected to thermostatted panel and installed hydraulically in parallel. After common output of evaporators, direct action pressure regulator is additionally installed, connected by its input to common output of evaporators, and by its output - to input of capacitor. Inside the body of hydro-accumulator to its input a branch pipe is connected with output aperture close to fuse zone, positioned near the output. Aforementioned branch pipe has additional contact apertures with fuse in its zone, positioned near the input. Electric heater is installed on external surface of hydro-accumulator near its input. In the zone positioned near the output the fuse is made with smaller cells compared to its remaining part.

EFFECT: ensured reliability of device in all modes of operation (heat emission) of devices under conditions of satellite operation.
