AUTONOMOUS LIQUID MULTI-MODE GROUND-BASED TEMPERATURE CONTROL SYSTEM OF A SPACE VEHICLE WITH A MULTI-MODULE HEAT EXCHANGER

摘要

FIELD: cosmonautics.;SUBSTANCE: invention relates to rocket and space technology and can be used in autonomous liquid multi-mode ground-based temperature control systems (GTCS) of service and scientific equipment of space vehicles (SV), modules and models of said vehicles, active phased antenna arrays (APAA). In the GTCS, the pumping line and the cooling agent return line are separated by a fine adjustment throttle. Each heat exchanger module is made in the form of a multi-channel monolithic body with internal straight-flow channels with the cross-sections equal in area. Either structural (finning) or inserted porous elements are provided in the channels, turbulising and intensifying the heat exchange process between the flowing cooling agent and the walls of the straight-flow channels of the heat exchanger modules with minimal hydraulic losses of the flowing cooling agent.;EFFECT: improved weight and size indicators of the system, structural simplification.;12 cl, 8 dwg
