EVAPORATOR FOR SPACECRAFT THERMAL REGULATION SYSTEM Russian patent published in 2018 - IPC F25B39/02 F28D7/10 

FIELD: heat exchange.

SUBSTANCE: invention relates to open loop heat exchangers in which the evaporation of the liquid refrigerant occurs directly into the environment (including into space), whereby it can be used in space technology. Evaporator is proposed for a spacecraft thermal control system containing a housing with inputs and outputs of the coolant and coolant. Body is made in the form of a cylinder with a cylindrical heat-conducting wall coaxially installed inside it. Longitudinal capillary grooves are formed on the inner surface of the wall, forming a coolant channel and a coolant channel between the housing and said wall, bounded by a cylindrical heat-conducting wall. On the outer surface of the cylindrical heat-conducting wall, staggered ribs are staggered. Refrigerant channel is equipped with an electrovalve for supplying the refrigerant in the pulsed mode, a nozzle for spraying the refrigerant and an outlet pipe, which is shielded on the channel side by a screening reflector.

EFFECT: technical result of the proposed invention is increased efficiency of the accelerator, both under zero gravity conditions and during overloads that occur when the spacecraft enters the Earth's atmosphere.
