FIELD: heat exchange.
SUBSTANCE: plate-type fin heat exchanger comprises a plurality of ribbed cold rows configured to conduct a first fluid, and a plurality of ribbed warm rows configured to conduct a second fluid. Ribbed warm rows contain inlet side and outlet side. First section of ribs of at least one ribbed warm row of multiple ribbed warm rows contains multiple combined lifts and recesses forming a wave configuration for each rib from the first section of ribs. Upstream front edge of the first section of ribs is located at the point of the wave configuration, which represents at least one of the ascents and recesses.
EFFECT: compromising the structural integrity of the heat exchanger and its ability to provide the required cooling performance.
