FIELD: heating.
SUBSTANCE: invention relates to heat engineering and can be used at manufacture of plate-type heat exchangers. A pack of heat exchange plates is provided for arrangement inside a block heat exchanger. The pack of heat exchange plates includes pairs (50, 60) of heat exchange plates, which are laid on each other so that path (67) of the flow for the first fluid medium is formed between pairs of heat exchange plates, which are laid on each other, with that, pair (50) of the pairs of heat exchange plates, which are laid on each other, includes the first heat exchange plate (51) and the second heat exchange plate (52), which are connected so that path (57) of the flow for the second fluid medium can be formed between the first and the second heat exchange plates. Pair (50) of heat exchange plates includes corrugation (101, 102) located on the corresponding side of elongated connection (72) connecting the first and the second heat exchange plates. Besides, the corresponding plate-type heat exchanger is described.
EFFECT: improving heat exchange inside a pack of heat exchange plates at provision of an ability of the heat exchanger to maintain high pressure levels.
