FIELD: heat exchange.
SUBSTANCE: heat-transfer plate (8) of heat exchanger (2) contains heat-transfer structure of flanges (36) and depressions (38) located in alternating order relative to central plane (C) of length. First and second adjacent combs (36) and recesses (38) extend obliquely in relation to the longitudinal central axis (I) of the heat transfer plate. First lower section of the first cavity is connected to the first upper section of the first crest by first slope (44a), and to the second upper section of the second ridge by second slope (44b), and the second upper ridge of the second ridge is connected to the second lower section of the second trough by third slope (44c). One of the first, second and third slopes comprises slope (46a, 46b, 46c) of the slope extending in the slope shoulder plane (S1, S2, S3) of the slope, which is offset from the central plane of the length. Therein distance L1 between first and second ridges confining first area A1 and distance L2 between first and second recesses delimiting second area A2 differ.
EFFECT: invention relates to the field of heat equipment and can be used in plate heat exchangers.
