PLATE HEAT EXCHANGER AND THE PLATE HEAT EXCHANGER MANUFACTURING METHOD Russian patent published in 2019 - IPC F28D9/02 F28F3/02 

FIELD: heating equipment.

SUBSTANCE: invention relates to the heat engineering and can be used in the art for liquid or gaseous media pre-heating, for example, as the recuperator. Plate heat exchanger contains the first section of the heat exchanger, which includes a cylindrical outer casing, one central and two peripheral separation rings, placed between the body and the rings and heat exchanger elements supported on the central separation ring, made of corrugated plates connected in pairs along their peripheral edges, at the same time, the heat exchange elements have flanges protruding beyond the peripheral edge, forming inlet and exhaust manifold windows, connected without a gap with the windows of the adjacent heat exchange elements and covered by separating rings, wherein the flanges, the central and peripheral rings form the internal heat transfer medium supply and removal manifolds, and the end parts of the heat exchanger are made in such a way as to ensure the possibility of passage between the heat exchange elements of the external coolant, at the same time, the heat exchanger is equipped with an additional section, similar in construction and located coaxially with the first section.

EFFECT: reducing the mass of the heat exchanger while increasing its efficiency and reliability.
