HEAT REGULATING SYSTEM OF SPACE VEHICLE Russian patent published in 2016 - IPC B64G1/50

Abstract RU 2577925 C2

FIELD: heating.

SUBSTANCE: invention relates to the heat regulating systems (HRS) of space vehicles (SV), mainly telecommunication satellites. The HRS liquid circuit contains a two-stage electric pump unit (EPU) with located in series impellers rotating with speed 6000 rpm. In circuit heat medium LZ-TK-2 (instead ammonia) is used. At EPU output the throttling orifice is provided, its hydraulic resistance ensures the minimum required heating medium flow. Without the orifice the circuit hydraulic resistance corresponds to maximum cooling capacity of the HRS. EPU can operate at higher (over 27 V) power voltage.

EFFECT: increased production effectiveness and reliability of long-term operation of any SVs with necessary cooling capacity from 5 to 13-18 kW.
