VORTEX HEAT EXCHANGER Russian patent published in 2024 - IPC F28D9/00 F28F9/07 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used in vortex heat exchangers with recuperative heat transfer. In a vortex heat exchanger comprising two adjacent coaxial vortex chambers formed by three flat discs, of which the extreme discs are covers, and the middle disc is a heat exchange surface, two cylindrical rings clamped between the discs, inlet and outlet nozzles located tangentially on the cylindrical rings and in the centre of both covers, wherein both vortex chambers are provided with arc-shaped plates secured in circumferential direction on central disc perpendicular to its plane. Plates have height equal to height of vortex chambers, and form a closed circuit dividing volume of vortex chamber into two spaces: peripheral — annular and central. Ends of adjacent plates are fastened to each other with overlapping by screws with formation of adjustable slots.

EFFECT: reduced hydraulic resistance of the apparatus, more uniform operation of the chambers of the apparatus and reduced pressure arising in it.
