Stacked-plate heat exchanger

A stacked-plate heat exchanger, comprising:

• a plurality of stacked plates stacked one on top of another;
• wherein the plurality of stacked plates include a plurality of first stacked plates and a plurality of second stacked plates stacked alternately one on top of another in a stacking direction;
• wherein each of the plurality of stacked plates includes a rim disposed around a periphery and extending in the stacking direction;
• wherein the rim of each of the plurality of stacked plates lies against the rim of an adjacent stacked plate of the plurality of stacked plates;
• wherein pairs of adjacent stacked plates 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, such that the pairs of adjacent stacked plates respectively define the first cavity and the second cavity in an alternating manner in the stacking direction;
• wherein a support structure mutually supports the plurality of stacked plates in an edge region of the plurality of stacked plates to stabilize the second cavity;
• wherein the plurality of stacked plates each has an end region disposed in a longitudinal direction that includes a first opening for the first fluid and a plurality of second openings, arranged around the first opening, for the second fluid;
• wherein the support structure and at least a portion of the second cavity are arranged in a region of the plurality of second openings;
• wherein at least some of the plurality of stacked plates include a plurality of webs, each web of the plurality of webs arranged between two adjacent second openings of the plurality of second openings;
• wherein the plurality of webs include a plurality of stamped webs and a plurality of unstamped webs arranged around the first opening in an alternating manner;
• and
• wherein the plurality of stamped webs project into the second cavity and lie against a stamped web of the adjacent stacked plate to form the support structure.
