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

FIELD: heating.

SUBSTANCE: shell-tube heat exchanger has casing with two lids, set of plates installed in casing, and heating medium supply and drain nozzles. Set of plates includes n similar plates located between two flat bases, plates are of mesh-flow type with vortex-generator in form of hollow double-side shoulders of same height in form of the truncated cones, along their tops the plates are tightened making mesh of mutual supports with rectangular structure and heating medium channels between them. At that the bases of the truncated cones are made in form of parallelograms, their sides are sides of the adjacent bases. The adjacent shoulders are connected with saddle-like jumpers. At that the flat bases of the plates set are connected with the casing lids.

EFFECT: increased intensity of heat exchange, assurance of operation at high pressures and high pressure differences of the heating medium.
