Abstract: The invention concerns a heat exchanger, in particular for a motor vehicle, comprising an array of tubes and fins, whereof the ends of the tubes are inserted in holes of a collector plate. The latter is generally planar and an inserting plate is arranged, directly mounted on the collector plate and provided with openings for allowing through the ends of the tubes and delimited by a peripheral edge forming a lateral stop for a rim of a manifold maintained by crimping means.

Abstract: The invention concerns a heat exchanger assembly for a motor vehicle comprising a main exchanger with a body mounted between two manifolds, whereto is assembled at least a secondary exchanger mounted between two manifolds such that a common air stream (F) can pass through the respective exchanger bodies. Each of the main exchanger manifolds is provided, at one end, with a projecting base forming a housing for a pin of the second exchanger, and at another end, with a projecting lug whereon can be locked a clip removably fitted on the secondary exchanger. Another secondary exchanger can be assembled in the same manner on the secondary exchanger.
