HEAT EXCHANGE MODULE Russian patent published in 2022 - IPC F28D7/10 F28D7/16 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering and can be used for the manufacture of modular heat exchangers. The heat exchange module is made in the form of a tube bundle with medium inlet and outlet pipes, consisting of heat exchange elements of the pipe-in-pipe type and including a block of heated (cooled) medium consisting of the inner surface of the outer pipes and the outer surface of the inner pipes with an annular gap between them, a block of heating (cooling) medium consisting of the outer surface of the outer pipes and inner surfaces of inner pipes, pipe boards of the inlet and outlet chambers in which the outer pipes are fixed, the bottoms of the inlet and outlet chambers in which the inner pipes are fixed, in this case, the supply and discharge of the medium into the annular gap can be carried out both perpendicular and coaxially to the heat exchange pipes, the number of heat exchange elements is n, where n is an integer from 2 to 3000, and the modules can be interconnected in sections from 2 to 1000 to obtain the necessary heat exchange surface, and the layout of the modules can be multi-pass, from 0 to 1/3 of the heat exchange elements located in the central part are made single-walled, while single-walled heat exchange elements and heat exchange elements of the pipe-in-pipe type satisfy the ratio of 0.1 D≤d≤D, where D is the outer diameter of the pipes of the heat exchange element of the pipe-in-pipe type, d is the outer diameter of the pipes of the single-wall heat exchange element.

EFFECT: reduction in the weight and size characteristics of the heat exchanger, simplifying the replacement of modules.
