FIELD: heating. ^ SUBSTANCE: invention may be used in different types of heat exchanging equipment, for instance recuperators, heaters, refrigerators, plate heat exchangers with soldered and non-soldered plates, coolers. Invention consists in the fact that in plate heat exchanger part of corrugations rows is arranged as basic, and rows of corrugations that are adjacent to basic row on both sides, are displaced relative to it and each other in the same direction, at that quantity of rows adjacent on side should be at least two. ^ EFFECT: increased intensification of heat exchange due to improvement of coolant flow turbulisation and balancing of their thermal and hydraulic properties, improved mechanical strength of corrugated spacing elements. ^ 1 dwg |
