MODULAR RADIATOR-HEAT ACCUMULATOR OF SPACE OBJECT PASSIVE SYSTEM FOR TEMPERATURE CONTROL Russian patent published in 2020 - IPC B64G1/50 G05D23/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering, and more specifically to heat accumulating devices. Modular radiator-heat accumulator of passive thermal control system of space object includes heat accumulators, heat pipes, heat accumulating substance, heat carrier, electric heaters, system of pipes and valves. Radiator-heat accumulator uses during latent heat of phase transitions of working medium. Housing of each of the heat accumulators is made in the form of a radiation panel, the outer surface of which is made in the form of a rectangular parallelepiped. Heat-accumulating substance is uniformly distributed in the continuous matrix phase with the volume fraction ε_mp, which contacts the inner surface of the housing and the heat accumulating substance (HAS) with density ρ and mass M, with the melting point T_melt^HAS. There coolant condensation zone with a volume fraction ε_chp of controlled heat pipe, the coolant in which the melting temperature T_melt^cool. Inner volume V of each heat accumulator corresponds to relationship: V = M/ρ⋅[(1 − ε_chp − ε_mp)]_.

EFFECT: improved reliability in operation is achieved.
