Plate-type heat exchanger, in particular evaporator and device for mounting a plate-type collector

摘要

Plate-type heat exchanger, in particular evaporator, with at least one collector (1) which has at least two metal sheets (2, 3, 4) abutting one another, which have asymmetries, in order to prevent faulty assembly of the metal sheets (2, 3, 4) ), wherein the sheets (2, 3, 4) arranged at their sides at least one cutout (12, 13, 14), each adjacent to a cutout (12, 13, 14) of an adjacent sheet (2, 3, 4), wherein the dimensions of the cutouts (12, 13, 14) of the individual sheets (2, 3, 4) differ in at least one direction of the sheet planes and the cutouts (12, 13, 14) are arranged such that in a projection of the cutouts (12, 13, 14) on a plane parallel to the sheet plane, the projections of the smaller cutouts (13, 14) with respect to the direction of the different dimensions are each within the projection of the largest cutout (12), wherein d he cutouts (12, 13, 14) of the individual sheets (2, 3, 4) differ in size in both the depth and in the width direction, wherein the smallest section in sheet thickness direction is arranged in front of the largest section or the larger cutouts.
