VORTEX HEAT EXCHANGER Russian patent published in 2020 - IPC F28D9/00 F28F9/07 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering, in particular to heat exchangers with recuperative heat transfer, and can be used in chemical, food and related industries. Most effective use of this device is possible at moderate and low consumption of heat carriers. In the vortex heat exchanger, comprising two adjacent coaxial vortex chambers formed by three flat discs, wherein the extreme disks are covers, and the middle disc is the heat exchange surface, by two cylindrical rings clamped between the discs. Inlet and outlet nozzles are located in the center of both covers and tangentially on cylindrical rings. Vortex chambers in the center at the location of branch pipes are additionally equipped with blades and cones, and branch pipes themselves are equipped with stops.

EFFECT: technical result consists in optimum ratio of reduction of hydraulic resistance of apparatus and higher strength of structure.
