Abstract

A stacked-plate heat exchanger may include a plurality of stacked plates. The plurality of stacked plates may include a plurality of first stacked plates and a plurality of second stacked plates stacked alternately one on top of another. Pairs of adjacent stacked plates may each delimit one of a first cavity for the passage of a first fluid and a second cavity for the passage of a second fluid in an alternating manner. The heat exchanger may also include a support structure that may support the plurality of stacked plates in an edge region to stabilize the second cavity. The plurality of stacked plates may each include a first opening and at least two second openings arranged around the first opening. The heat exchanger may also include a plurality of webs each arranged between two adjacent second openings. The plurality of webs may form the support structure.
