FIELD: power industry. ^ SUBSTANCE: plate-type heat exchanger includes many heat exchange plates, the first end plate and the second end plate. Plates are rigidly attached to each other by means of brazing metal. Each heat exchange plate has heat transfer area and many areas with the hole, which envelope the corresponding hole. Plate-type heat exchanger includes many flat elements containing lower surface directed towards heat exchange plates. At least one of the flat elements includes annular projection continued from lower surface and tightly adjoining one of the areas with the hole of the end heat exchange plate. ^ EFFECT: creation of plate-type heat exchanger with high design pressure. ^ 15 cl, 11 dwg |
