PLATE HEAT EXCHANGER WITH HEADER FOR SEPARATION OF HOT AND COLD HEAT CARRIER Russian patent published in 2024 - IPC F28D9/04 B33Y80/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used for heating liquid or gaseous media. Heat exchanger consists of two sections, the first of which is limited by annular walls with inner D₁ and outer D₄ diameters. Walls form cylindrical separating surfaces between them, between which there are channels of the first heat carrier and channels of the second heat carrier with inlet and outlet openings. Second section comprises front annular wall with inner D₂ and outer D₃ diameters. Annular walls form between themselves an external surface of n-order with transition from diameter D₂ to diameter D₁ and external surface of n-order with transition from diameter D₃ to diameter D₄. Between the surfaces there are collectors for removal of the first heat carrier. Walls form inner surface of n-order between themselves with transition from diameter D₂ to D₄. Between the surfaces there are collectors for supply of the second heat carrier. Second section is connected along the wall to the first section, besides, the sections are located coaxially and are made as a whole. Channels of the first heat carrier are connected to the first heat carrier discharge manifolds through the outlet openings, the second heat carrier supply manifolds are connected to the second heat carrier channels through the inlet openings. Heat exchanger is made by selective laser fusion.

EFFECT: increased compactness factor of heat exchanger due to increased area of heat exchange surface.
