Abstract: The tube (5) of a heat exchanger (1) is produced from a strip of material (11), the strip of material (11) having two end parts joined such as to form the tube (5). The strip of material (11) forming the tube (5) is folded on itself such as to define at least one fold (13) formed by two strip portions (13a, 13b) with continuity of material. At least one strip portion (13a, 13b) of the fold (13) is a strip portion (13a, 13b) for protecting the tube (5) in the event of an impact from an element outside the tube (5) and is formed in an intermediate part (11 b) of the strip of material (11).

Abstract: A heat exchanger is disclosed. The heat exchanger includes a protective device, mutually parallel tubes through which a first fluid circulates, and perpendicular fins connecting two successive flat tubes, a second fluid circulating between said flat tubes by passing through said fins, the protective device being apertured so as to allow the circulation of the second fluid through the fins. The protective device includes fixing spikes which are inserted forcibly between the fins.

Abstract: The invention relates to a device for the thermal regulation of a motor vehicle battery pack (1) comprising at least one battery (5) contained in a housing (3), the thermal regulation device comprising: at least one heat exchanger (9) in contact with the battery (5), at least one elastic element (15) arranged in the bottom (14) of the housing (3) so as to hold the heat exchanger (9) against the battery (5). An insulator (13) is interposed between the elastic element (15) and the heat exchanger (9).

Abstract: The present invention concerns a heat exchanger (1) comprising: a tube bundle (2) comprising a plurality of tubes (20) arranged parallel to each other and spacers (21) arranged between said tubes (20), a collector plate (4) comprising holes (43) respectively bordered by first flanges (44) into which ends (22) of the tubes (20) are inserted, the tube bundle (2) being brazed and the collector plate (4) comprising at least one compressible seal (41) forming second flanges (45), the second flanges (45) being compressed between the first flanges (43) and the ends (22) of the tubes (20) in order to provide a tight seal between said ends (22) of the tubes (20) and the corresponding first flanges (43).

Abstract: The invention relates to a method for producing a heat exchanger tube (1) by bending a metal strip (11), said tube (1) having an internal partition (19) formed by joining the ends of opposing edges (11a, 11b), said partition facing a projection (50) that extends into the heat exchanger tube (1) at a joining zone (22). The method comprises the following steps: locally stamping the metal strip (11) in order to produce a projection at the joining zone (22); and bending the metal strip (11) in order to form said heat exchanger tube (1), such that the projection extends into the tube (1). The invention also relates to such a tube (1) and to a heat exchanger (3) comprising a bundle of said tubes (1).
