Abstract: A heat exchanger for heat exchange between at least two fluids, especially for a motor vehicle, comprises a bundle (7) for heat exchange between said fluids, and a housing (9) for receiving said bundle (7), said housing (9) having at least one raised edge (11). The heat exchanger also has a seal (15) of a rigid plastic material, said seal enveloping said at least one raised edge (11) and being designed to ensure the tightness between the exchanger and a container of said exchanger. The heat exchanger can also be included in an air intake device including such a heat exchanger and an air intake collector.

Abstract: The invention relates to a device for mixing a stream of supercharging air and a stream of recirculated exhaust gases. The device comprises a manifold allowing the stream of air and the stream of recirculated gases to be mixed, and allowing the mixture to be distributed in the cylinder head. The device also comprises means for conveying the recirculated exhaust gases in the manifold that allow the distributed injection of the recirculated exhaust gases into the stream of supercharging air. The device additionally comprises means for thermally insulating the conveying means in order to limit the cooling of the recirculated exhaust gases by the supercharging air.
