Plate-shaped heat exchanger for a cooling device comprising at least one heart exchanger package

摘要

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.

主权项

1. A plate-shaped heat exchanger for a cooling device comprising at least one heat exchanger package, wherein the heat exchanger package comprises a plurality of openings for accommodating a tube conducting a coolant, wherein each opening is surrounded by a rim hole and a plurality of projections are distributed between the rim holes for heat exchange with the medium to be cooled, wherein a plurality of projections are arranged around a rim hole, wherein the projections have a shape which ensures a targeted heat conduction from the projection to the rim hole, wherein the ends of the projections are arranged approximately circularly around the rim hole and extend orthogonally away from the rim hole, wherein a turbulator or spacer is arranged between adjacent rim holes, wherein the turbulator or spacer supports a heat exchanger package situated above, wherein a bead is arranged between adjacent rim holes in an edge region of the plate-shaped heat exchanger, wherein the edge region comprises a corrugation.
