A plate-type heat exchanger is provided with a sealing device positioned between pairs of adjacent plates (12). Said device comprises a gasket (11) placed inside of a suitable peripheral groove (21), as well as a plurality of protuberances (10) projecting from a peripheral area (13) of said gasket (11) towards a peripheral area of the plate (12) to which said device is coupled. Said heat exchanger is provided with a plurality of recesses (19) having a predetermined shape and placed along the peripheral edge of each plate (12) constituting said heat exchanger; furthermore, each protuberance (10) has a shape which is conjugated to the shape of the corresponding recess (19) so that said protuberance (10) can interact with said corresponding recess (19) in such a way as to insert an edge of said recess (19) inside of a groove (16) provided in each protuberance (10).
A plate-type heat exchanger provided with a sealing device positioned between pairs of adjacent plates, said sealing device comprising a sealing gasket for location with a suitable peripheral groove provided on a respective plate, and a plurality of protuberances projecting from a peripheral area of said gasket towards a peripheral area of the plate with which said device is located, said protuberances being provided with a strengthening rib extending longitudinally along said protuberances, the protuberances having a rectangularly shaped first portion perpendicular to the respective plates, and a discoidally shaped second portion, said second portion being connected to the sealing gasket by said first portion, the plates being provided with a plurality of recesses having a predetermined shape and being positioned along the peripheral edge of respective plates, and the protuberances having a shape which is conjugated to the shape of the corresponding recesses so that said protuberances interact with the corresponding recesses such that an edge of respective recesses is inserted in a groove provided on the respective protuberances.
A plate-type heat exchanger provided with a sealing device positioned between pairs of adjacent plates, the plates including a plurality of recesses having a predetermined shape and position along the peripheral edge of the plates, said sealing device comprising a sealing gasket placed in a groove provided on the respective plates, a plurality of protuberances projecting from a peripheral area of said gasket towards a peripheral area of the plate in which said device is located, said protuberances having a shape for engaging the corresponding recesses so that said protuberances interact with said corresponding recesses with an edge of said recesses inserted in a groove provided on respective protuberances, the protuberances having a first portion and a second portion of predetermined shape, and a strengthening rib directed between the first portion and the second portion of the protuberances.
A sealing gasket for use in a plate-type heat exchanger including pairs of adjacent plates having recesses, the sealing gasket comprising:
