VORTEX HEAT EXCHANGER Russian patent published in 2022 - IPC F28D20/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used in heat exchangers with recuperative heat transfer. In a vortex heat exchanger containing two adjacent coaxial vortex chambers with inlet and outlet nozzles formed by three flat discs and two cylindrical shells, a shaft is installed in the center of the outer discs connecting the first vortex chamber with the second. The shaft is fixed on the middle disk, both ends of the shaft are equipped with impellers, which are rigidly fixed at its ends, with the possibility of performing the function of a turbine or a flow activator.

EFFECT: increase in the driving force of the heat exchange process, an increase in the efficiency of heat exchange even at low flow rates of one of the heat carriers, an increase in the amount of heat transferred.
