FIELD: heating.
SUBSTANCE: invention refers to heat engineering and can be used in plate-type heat exchangers. A heat exchanger containing a pack consisting of a group of pairs of heat exchange plates (1b, 1c) made from metal plates having a three-dimensional relief (2, 3), besides, inside the above group of pairs there formed is the first flow passage, and between the above pairs of heat exchange plates there formed is the second flow passage; each heat exchange plate has at least one through hole (5-8); besides, the heat exchanger also includes an end plate (1a) being the extreme plate of the heat exchanger, which is thicker and made from stiffer material than the above heat exchange plates; the through hole of the above end plate (1a) has a projecting edge (9) forming a flange (10).
EFFECT: improved heat exchanger structure.
