PLATE HEAT EXCHANGER AND THE PLATE HEAT EXCHANGER MANUFACTURING METHOD Russian patent published in 2018 - IPC F28D9/02 

FIELD: heating.

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 comprising the cylindrical outer shell, one central and two peripheral separation rings arranged between the housing and the rings, and heat exchange elements resting against the central separation ring, made of in pair connected along the peripheral edges corrugated plates, at that, the heat exchange elements have projecting beyond the peripheral edge flanges, forming the inlet and outlet manifold windows, without a gap connected to the adjacent heat exchange elements windows and covered by the separating rings, wherein the flanges, the central and peripheral rings form the internal heat transfer medium supply and removal manifolds, and the heat exchanger end parts are made so, that to allow the external heat transfer medium passage between the heat exchange elements.

EFFECT: heat exchanger weight reduction and increase in the tightness and strength.
