HEAT EXCHANGER Russian patent published in 2019 - IPC F28D7/16 F28F1/02 

FIELD: heat exchange.

SUBSTANCE: heat exchanger made using additive technologies (3D printing) comprises heat transfer unit consisting of main and two end sections. Heat-transfer unit is formed longitudinally oriented, having common walls on all their length channels, located on the main section in staggered order for each of heat-exchange media. At the outlet of the end sections of the heat-transferring unit, the channels have a shape which can be inscribed into a non-equilateral rectangle and turned at the same angle to form rows between which the partition wall protrudes above the end surfaces of the heat-transfer unit.

EFFECT: baffle divides the rows of channels of different heat exchange media into channels opening into supply and discharge headers with heat exchange media supply and discharge branch pipes.
