Abstract: The invention relates to a heat exchanger for thermally treating a vehicle cabin. The heat exchanger includes a core portion made of at least a plurality of tubes and a plurality of fins. The heat exchanger includes at least one header tank located at one end of the core portion. The header tank includes at least a collecting plate which have a U-shape, a cover plate connected to the collecting plate and at least one cap plate which is located at one longitudinal end of the header tank. The collecting plate and the cover plate are linked together by an overlapping portion and the cap plate is maintained in position within the header tank by a tongue made in continuation of the overlapping portion.

Abstract: A heat exchanger includes a tank, spaced apart tubular elements, fins and a side cover. The tank receives a first heat exchange fluid therein. The spaced apart tubular elements defining a heat exchanger core are in fluid communication with the tank and enable heat exchange between a first heat exchange fluid flowing there through and a second heat exchange fluid flowing around and across the tubular elements. The fins arranged alternately with respect to the tubular elements promote heat exchange. The side cover adjacent to a lateral face of the heat exchanger core, covers and shields the lateral face and at least a portion of the heat exchanger core disposed between the tubular elements proximal to the lateral face of the heat exchanger core and the corresponding side cover.
