PLATE AND SHELL HEAT EXCHANGER Russian patent published in 2015 - IPC F28D9/00 F28F3/08 

FIELD: heating.

SUBSTANCE: plate and shell heat exchanger includes a housing with two covers, heat carrier inlet and outlet branch pipes and a bank of plates installed in the housing and provided with holes forming headers of the first heat carrier; with that, between the above headers there located are ducts of the second heat carrier. The bank of plates is made in the form of a circular cylinder and consists of a section. The section includes n similar plates of a mesh-flow type with turbulisers in the form of hollow two-sided projections of the same height in the form of flattened cones, on apexes of which the plates are tightened, which form a net of mutual supports with a rectangular structure between each other and heat carrier ducts between each other. Bases of flattened cones are made in the form of parallelograms, the sides of which are sides of adjacent bases. The adjacent projections are connected with seat-shaped cross-pieces.

EFFECT: increasing heat exchange intensity; providing a possibility of operation at high pressures and at high differential pressures of heat carriers.
