Abstract

The invention concerns a plate-type heat exchanger comprising a stack of plates of the same shape, preferably made of stainless steel, each of which is turned through 180° in its own plane with respect to the adjacent plates and whose heat-exchange surfaces are structured. This heat exchanger is characterized in that the plates have perforations at certain points where the surface structures of two plates touch. In addition, the flat areas round two of the symmetrically disposed fluid-flow orifices have, on both sides of the plate, raised embossing as high as the surface structures. The edge (1) of each plate is arranged at an angle of less than 90° in a dish shape and all the touching areas of the plates, in particular round the perforations and the fluid-flow orifices (3), and the dish-shaped edges (1) are laser-welded together. The invention also relates to a plate-type heat exchanger according to claim 1, characterized in that the perforations have a diameter from 0.2 to 2 mm, preferably from 0.5 to 1mm.
