<p>The invention relates to a heat exchanger which includes prestamped metal plates (1, 2) assembled, by welding, two-by-two on two opposite sides thereof so as to form stacked modular elements defining two separate circuits for two fluids, respectively. The plates comprise, on the broad side thereof, parallel ribs (4, 5) giving said plates a corrugated profile, as well as bosses (6), the tops (7) of which are located in the plane that contains the bases or tops of the ribs. The tops (7) of the bosses (6) of one plate (1) are welded to the tops of the corresponding bosses of another plate (2). The heat exchanger thus combines the features and advantages of ribbed plates and clad plates. The invention also relates to a plate (1, 2) forming a component of such a heat exchanger.</p> |
