ABSTRACT:
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° to 90° with the longitudinal axes of the first corrugations.
