HEAT EXCHANGER Russian patent published in 2021 - IPC F28D9/00 F28F3/02 

FIELD: power engineering.

SUBSTANCE: heat exchanger (1) is proposed for heat exchange between first fluid medium passing in longitudinal direction (X) and second fluid medium, wherein said heat exchanger (1) comprises: two parallel plates (6) spaced apart so as to form passage (7) for circulating said first fluid, at least one first and one second rows (8a, 8b) of ribs (9) located perpendicularly between said plates (6), wherein said first and second rows (8a, 8b) extend in a longitudinal direction, wherein ribs (9) of said first row (8a) are preferably arranged in staggered order relative to ribs (9) of said second row (8b), wherein each rib (9) is limited in longitudinal direction by first edge (10) and second edge (11), wherein said first edge (10) has on each of its ends a zone of connection with corresponding plate (6). Said zones of connection of said first edge (10) are inclined respectively at angle (A) and at angle (B) relative to normal (N) to plates (6) in plane (P), perpendicular to said plates (6) and parallel to direction (X), wherein said first edge (10) and said second edge (11) of each of ribs (9) have an identical profile in said plane (P).

EFFECT: invention allows observing required dimensional and geometric tolerances after fabrication.
