CRYOSYSTEM OF AN AVIATION INTEGRATED ELECTRIC POWER PLANT BASED ON HTS Russian patent published in 2022 - IPC F25B19/00 F17C3/04 

FIELD: cooling systems.

SUBSTANCE: invention relates to devices intended for providing cryogenic cooling of high-temperature superconducting (HTS) devices. Cryosystem of an aviation integrated electric power plant based on high-temperature superconductivity contains a tank with a cover on which the cryosystem pressure and temperature control means and branch pipes are mounted for supply of working coolant and supply of inert gas to maintain standard atmospheric pressure in tank; at least one cooling circuit comprising a working coolant supply line with means for injecting said coolant into the line and means for controlling temperature, pressure and flow rate of the working coolant; return line with temperature, pressure and working coolant flow control means; vacuum pumping line; plate heat exchanger installed in the tank. Heat exchanger plates are arranged to form two chambers. Main supply of the working coolant is connected to the first chamber, the vacuum pumping line is connected to the second chamber equipped with a throttle valve.

EFFECT: proposed cryosystem provides stable supply of working coolant to consumers, increases efficiency of cooling and reduces consumption of working coolant.
