1. a heat-exchangers of the plate type (100);

  • Comprise some heat exchanger plates (1);

    It is arranged side by side mutually and is connected and formation sheetpile stack (2) mutually with the soldering ways of connecting;

    Wherein heat exchanger plate (1) is basically with the stainless steel manufacturing that contains chromium;

    Wherein heat-exchangers of the plate type (100) comprises the plurality of ports passage (16,18) that extends through at least some heat exchanger plates (1);

    And wherein heat-exchangers of the plate type (100) also comprises the end plate (3,5) of each end of overlay storehouse (2);

    And have a port holes (6,7,10,11) relevant with port channel (16,18);

    It is characterized in that;

    at least one end plate (3,5) has at least one port holes that is provided with lid (9,12) (6,7,10,11);

    And said lid comprises the device (9,12) of the intensity that is used for increasing lid (9,12) and is used at least one end plate (3,5) is close proximity to the device (14,15) of heat exchanger plate (1) sealing of adjacent setting, and wherein being used to the device (9,12) of gaining in strength is to be formed by the surface offsets of lid (9,12) with the device (14,15) that is used to seal, and the surface offsets that wherein is used to the device (9,12) of gaining in strength and the device (14,15) that is used to seal forms vertically extending towards opposite basically direction about end sheet surface;

    Be used for the device (14,15) that said at least one end plate (3,5) is close proximity to heat exchanger plate (1) sealing of adjacent setting is formed as the embedding area of the port port lid that forms annular embedding area, said annular embedding area is close proximity to heat exchanger plate (1) sealing of said adjacent setting.
