Abstract
A method of making an end-piece for a plate heat exchanger, wherein the end-piece includes a frame part having inner and outer portions, and an intermediate portion arranged between the inner and outer portions, with the outer wall surface of the inner portion being arranged to face a first surface of a package of heat transfer plates comprising the plate heat exchanger, and the first surface having a center portion and a peripheral portion encircling the center portion. The method includes extruding the frame part with plural cavities in the intermediate portion of the frame part that extend in the extrusion direction of the frame part and that are parallel to the frame part axis, with outer dimensions of the outer wall surface of the inner portion configured to be at least as large as outer dimensions of the center portion of the first surface heat transfer plate package.
