FIELD: heat exchange.
SUBSTANCE: invention relates to plate-type heat exchanger (1) having multiple parallel heat exchange channels (30) separated by separating plates (4). Each heat exchange channel (30) of heat exchanger is limited on at least one side by end plate (8), note also that each end plate (8) has first surface (81) and second surface (82) facing away from first surface (81). Said two surfaces (81, 82) are soldered to corresponding paired separating plate (4). According to the invention, each of two surfaces (81, 82) has surface structure (9) with a plurality of uniformly elevated elevations and recesses, wherein distance (B) from one elevation to adjacent elevation (802) or from one recess to adjacent recess (801) ranges from 0.1 mm to 2.5 mm.
EFFECT: proposed are end plates with surface structure for plate heat exchangers.
