FIELD: heating.
SUBSTANCE: invention refers to heating engineering and can be used in plate-type heat exchangers. Plate heat exchanger includes multi-plate staple, each plate having fluid medium inlet and outlet. Every two adjoining plates are interconnected in areas where top parts of corrugated section of the lower plate and bottom parts of corrugated section of the upper plate overlap if viewed in direction of stapling. Particularly, upper part out of top corrugated section parts of lower plate, adjoining both inlet and outlet, has flat form.
EFFECT: enhanced compression strength of plate heat exchanger.
