Device for exchanging heat

A device for exchanging heat, in particular for cooling the combustion air of internal combustion engines in motor vehicles with at least one feed means and one discharge means of a first medium such as a refrigerating agent, and at least one feed means and one discharge means of a second medium, such as the combustion air, at least one flow device for the first medium, such as the refrigerating agent, and one flow device for the second medium, such as the combustion air, wherein the flow paths of the flow devices of the first medium and of the second medium are separated from one another and the flow directions are at least partially different, characterized in that the flow devices are accommodated in an at least two-component, contoured housing, wherein a first housing component has an essentially U-shaped outline cross section which is closed by a second, essentially planar housing component at the open side of the first housing component, and in that the housing has, on two opposite sides, at least one inlet flange and at least one outlet flange for the second medium, and in that the flow devices are held spaced apart from one another in at least one region by means of at least one frame device which is accommodated in the housing.
