Abstract

A heat exchanger may include a plate, a seal and a cover. The plate may have at least two receiving grooves having a respective groove base, an intermediate region disposed in a plane between a plurality of rim holes, and a ramp extending between the intermediate region and the respective groove base of the at least two receiving grooves. The seal extends in the at least two receiving grooves. The ramp may be rounded at a transition to the receiving grooves with a first radius and at a transition to the intermediate region with a second radius, and the ramp may be inclined between 20°<α<65° relative to the intermediate region or has an S-shaped progression. An inflection point of the plate may be arranged in a region from 10% to 80% of a height difference between the intermediate region and the respective groove base.
