A corrugated fin, in particular for a heat exchanger, having a substantially corrugated design, having a plurality of fin surfaces, wherein adjoining fin surfaces are connected to one another by means of a fin arch in such a way that a medium can flow through an intermediate space between adjoining fin surfaces, wherein the fin surfaces are arranged at an angle with respect to one another perpendicularly with respect to a throughflow direction for the medium, wherein the fin surface has at least one bulge which protrudes out of the plane of the fin surface, wherein the extent of the bulge in a direction perpendicularly with respect to the air throughflow direction is smaller than the extent of the fin surface in said direction.

Corrugated fin and method for producing it

The invention relates to a plate-shaped heat exchanger for a cooling device comprising at least one heat exchanger package, in particular for a motor vehicle, consisting of a plurality of openings for accommodating a pipe conducting a coolant, wherein each opening is surrounded by an passage and a plurality of projections are distributed between the passages for the heat exchange with the medium to be cooled. In order to allow a high performance increase of a cooling device, yet a low increase in pressure loss of the charge air, a plurality of projections are arranged around an passage, wherein the projections have a shape that assures deliberate heat conduction from the projections to the passage.
