SPACECRAFT Russian patent published in 2003 - IPC

FIELD: space engineering; designing spacecraft. SUBSTANCE: spacecraft has target equipment compartment, instrument compartment, power equipment compartment with engine plant, power supply system with solar battery, automation and voltage stabilization complex, storage batteries mounted on heat exchange units forming monoblocks, temperature control system with hydraulic loops and units for taking, supplying and removing heat in form of thermal plates and emitting external radiators included in loop of said temperature control system. Monoblocks are provided with thermal pipes located in parallel at preset distance relative to each other. End parts of these pipes form condensation areas; they are combined in separate thermal plates by means of plate made from heat-conducting material. Tubes of capillary structure secured to thermal plates through heat-conducting material perform function of capillary pump forming evaporation zone of thermal tube. Groups of thermal plates are interconnected in parallel and are connected to external emitting radiator by means of pipe lines, thus forming autonomous loop. EFFECT: increased service life; reduced mass; enhanced reliability. 1 dwg
