Claim Text:
1. A heat exchanger arrangement comprising: a first housing part comprising an outer circumferential wall, an inner circumferential wall and an inner bottom wall adjoining said inner circumferential wall in an inner circumferential wall end area, said outer circumferential wall, said inner circumferential wall and said inner bottom wall being integrally connected with one another to define a single, one-piece housing wall structure; and a second housing part comprising an outer bottom wall connected to said outer circumferential wall in an outer circumferential wall end area, said first housing part and said second housing part defining a pot-shaped heat exchanger housing that is elongated in a direction of a longitudinal axis and with a circumferential wall area and with a bottom wall area in an end area of said circumferential wall area and with a heat carrier medium flow space for heat carrier medium formed in said heat exchanger housing with a circumferential flow space and with a bottom flow space that is in connection with said circumferential flow space, said heat carrier medium flow space being enclosed by said first housing part and said second housing part, said inner circumferential wall and said outer circumferential wall defining at least a portion of said circumferential flow space, said outer bottom wall and said inner bottom wall defining at least a portion of said bottom flow space, said second housing part comprising an axially extending connection area in an outer edge area of said outer bottom wall, said second housing part being connected to said first housing part via a fluid-tight press fit connection, said axially extending connection area engaging said outer circumferential wall, wherein said axially extending connection area and said outer circumferential wall define at least a portion of said fluid-tight press fit connection, wherein said outer circumferential wall comprises an outer circumferential wall surface, said outer circumferential wall surface extending in a radial direction with respect to a longitudinal axis of said first housing, said outer bottom wall comprising an inner bottom wall surface, said inner bottom wall surface extending radially with respect to said longitudinal axis of said first housing, said inner bottom wall surface being in direct contact with said outer circumferential wall surface.
