A method is provided for manufacturing a bundle of plates for a heat exchanger made up of a stack of plates. The method includes reducing by machining the initial thickness of each plate by making at least at the periphery of the plate, at least one connecting shoe having a height greater than the thickness of the machined plate, forming on the central portion of the plate, corrugations, to be superposed pairwise on the plates, connecting the shoes in contact with the plates of each pair through a weld bead, superposing the pairs of plates and connecting the shoes in contact with the pairs of plates through a sealed weld bead by arranging a superposition of open or closed ends for alternate inflow or outflow of said fluid.

Method for manufacturing a bundle of plates for a heat exchanger

The heat exchanger plate presents first adjacent first corrugations generally directed along respective alignment axes in the longitudinal direction of the plate and comprising successive segments that are substantially rectilinear and oblique, being successively inclined in a first sense and in a second sense relative to the longitudinal axis. The heat exchanger plate also has at least one deformation zone constituted by at least one set of segments of second corrugations of generally transverse direction intersecting the set of longitudinal axes along which the first corrugations are disposed. The alignment axes of the segments of second corrugations make an angle lying in the range 45&#xb0; to 90&#xb0; with the longitudinal axes of the first corrugations.
