<p>The present invention relates to a heat exchanger (1) including an assembly of plates vertically adjacent in a stack (2), characterised in that said assembly includes a plate of a first type (10) and a plate of a second type (20) that is different from said first type (10), the plate of the first type (10) being alternated with a of plate of the second type (20) in the stack (2) of plates (10, 20), each plate (10, 20) extending substantially in the same general plane (P) and including a plurality of profiled edge portions (11, 12, 13, 21, 22 and 23) distributed over the contour (3) of the plate (10, 20), and at least two profiled edge portions (11, 21) including at least a first linking surface (4) and a second linking surface (5), said first linking surface (4) and said second linking surface (5) being arranged on two separate vertical levels (n1, n2) on either side of the general plane (P) of the plate (10, 20) and arranged at two different distances (d1, d2) from the contour (3) of the plate, wherein the first linking surfaces (4) of a plate of the second type (20) can be placed vertically adjacent to the first linking surfaces (4) of a plate of the first type (10) and the second linking surfaces (5) of a plate of the first type (10) can be placed vertically adjacent to the second linking surfaces (5) of a plate of the second type (20).</p> |
