Claim Text:
1. A plate heat exchanger comprising: a plurality of plates stacked one upon the other forming a stack of plates, each of the plurality of plates alternately span a first and a second flow space for forming a first and second medium respectively, wherein each plate has a circumferential edge and a basin-shaped design, and wherein two adjacent plates are in each case connected to each other via the circumferential edges, an end plate fixedly connected to at least one adjacent plate at at least one end of the stack, wherein the circumferential edge of the at least one adjacent plate is supported on the end plate by a wall face of the end plate, the edge of the at least one adjacent plate is formed at least generally parallel to and is fixedly connected to the wall face, wherein the at least one adjacent plate is a lowest plate of the plurality of plates and is included in whole within a depression within the end plate, and the end plate includes an upper planar surface and a lower planar surface, and the depression therein is between the upper and the lower planar surfaces, and the end plate is defined to have a unitary thickness between the upper planar surface and a bottom of the depression, and the unitary thickness extends beyond the circumferential edges of the plates, wherein the end plate includes an aluminium alloy and the wall face is formed between two parallel surfaces of the end plate, wherein the two parallel surfaces include the upper planar surface and the lower planar surface; further comprising a turbulence insert arranged between the at least one adjacent plate and the end plate.
