<p>The invention relates to a heat exchanger comprising a cooling core consisting of a plurality of parallel tubes and cooling fins, two header tanks (3) fluidly connected with opposite ends of each tube and end caps brazed to and tightly closing upper and lower ends of each header tank (3). The invention relates also to an integrated module comprising two heat exchangers of this type and coupled with common end caps (4a), in particular a vehicle CRFM (Condenser, Radiator, cooling Fan Module). To enable a one-shot brazing operation of the heat exchanger or the integrated module, each end cap (4a) has a flat surface (5) closing and recessed inside the header tank (3) profile and provided with a bead (7) on the periphery thereof, and at least two protrusions (8) adjoining to the side walls of the header tank (3) and provided with C-shaped latches (9), the ends of which engage on the corresponding projections (10) on external side walls of the header tank (3).</p> |
