Heat exchanger arrangement, method for producing a heat exchanger arrangement, and internal combustion engine having the heat exchanger arrangement

A heat exchanger arrangement comprising:

• a housing comprising a fluid inlet for receiving a fluid in the form of heated air and a fluid outlet for discharging the fluid in the form of cooled air, the housing formed of a first shell and a second shell;
• and
• a heat exchanger arranged in the housing between the fluid inlet of the housing and the fluid outlet of the housing and surrounded by the housing;
• wherein the heat exchanger is arranged such that the fluid can flow through the heat exchanger;
• wherein the housing comprises a seal contour formed on at least one of the first shell and the second shell;
• wherein the seal contour of the housing comprises a meltable and formable plastic material that is materially fused to a seal surface of the heat exchanger at the fluid inlet of the housing or at the fluid outlet of the housing;
• and
• wherein a seal surface of the seal contour of the housing toward the heat exchanger is separate from and coplanar to a seal surface of one of the first shell and the second shell toward the other one of the first shell and the second shell.
