Abstract
Abstract Disclosed is a device for exchanging heat, especially for cooling the combustion air of internal combustion engines in motor vehicles, which is characterized by the fact that the flow devices ( 14 ) are accommodated in an profiled housing ( 6 ) comprising at least two parts. The cross section of a first housing part ( 6 a ) is essentially U-shaped, said basic shape being closed at the open end of the first housing part ( 6 a ) by means of a second, substantially planar housing part ( 6 b ). The inventive device is further characterized by the fact that the housing ( 6 ) comprises at least one inlet flange and at least one outlet flange for the second medium at two opposite sides while the flow devices ( 14 ) are kept at a distance from each other in at least one area by means of at least one frame device ( 12 ) which is accommodated within the housing ( 6 ).
