Claim:
1. A plate suitable for acting as a bulkhead between two fluids flowing in a plate heat exchanger, the plate possessing edges meeting at two corners and a diagonal joining the two corners, the plate possessing an outer periphery and comprising: a plurality of corrugations each having a bottom crest line and a top crest line, all of the bottom crest lines and all of the top crest lines of the plate being parallel to one another; at least some of the corrugations of the plate locally comprising stiffeners formed by a local reduction of the height of the top crest line from a first height of the top crest line; the stiffeners being arranged in a first group of stiffeners distributed on the plate along at least one first line parallel to the diagonal of the plate, the diagonal being perpendicular to the crest lines of the corrugations; the stiffeners of the first group being alternately arranged on either side of the first line on each consecutive corrugation; the distance measured perpendicularly to the first line from the center of the stiffeners of the first group to the first line being the same for each stiffener of the first group; and each of the corrugations that includes a stiffener arranged on one side of the first line at the perpendicular distance from the first line possessing a height equal to the first height on the other side of the first line at the perpendicular distance from the first line.
