MULTI-PASS HEAT EXCHANGER Russian patent published in 2021 - IPC F28F9/22 

FIELD: power engineering.

SUBSTANCE: plate heat exchanger (1) comprises set (2) of patterned heat transfer plates (10) mounted on top of each other and located inside casing (300). These plates define the first flow path and the second flow path between the plates. In the space between other edges (15) of heat transfer plates (10) and the inner wall of casing (300), external distribution chambers (4, 5) are formed, communicating through the fluid with the first flow path and first flow connections (6a, 6b). In external distribution chamber (4, 5), adjustable partition (100) is located, dividing it into two external sub-chambers (4a, 4b, 5a, 5b), with the formation of a barrier for the flow. Partition (100) is adjustable so that it can be connected to plates (10) inserted between any of heat transfer plates (10).

EFFECT: invention makes it possible to create a heat exchanger, the configuration of which is adjustable and even replaceable.
