Abstract:
1. A stacked plate heat exchanger, comprising a multiplicity of plates of a first type and a second type stacked on top of one another so as to form first flow passages for a first medium and second flow passages for a second medium, wherein pairs formed by one first type and one adjacent second type of plates define between them said first flow passage, and adjacent pairs of plates form between the adjacent pairs said second flow passages, the stack of plates forming a heat exchanger block having a top side and an underside and having in each case two opposite side faces and opposite end faces, wherein the first flow passages for the first medium are closed at their peripheral sides and are in fluid communication with distribution and collection passages, which are arranged perpendicular to the plane of the plates and respectively open out into inlet and outlet connection pieces arranged on the top side and/or underside of the heat exchanger block, wherein the second flow passages are designed to be largely open at the end faces such that the open sides form an inlet plane and an outlet plane for the second medium, and wherein the second type of plates have lateral flanged edges which are bent at a right angle with respect to the plane of the second type plate in a direction away from its respectively paired first type plate and toward the adjacent pair of plates, and in the bent portion of the lateral flanged edge contains a solder surface adapted to be soldered to at least one of the first type or second type plate of the adjacent pair of plates, to close off the second flow passages at the side faces with respect to the outside and form the side faces of the heat exchanger block.
