Abstract (en)
[origin: FR2886185A1] The brazing of a folded tube for a heat exchanger consists of placing a first tube part (20) in contact with a contact surface of a second tube part (22) and brazing the two tube parts at the level of the contact zone using a brazing deposit and a brazing flux to form the brazed liaison. The brazing flux (32) is applied on the contact surface of the second tube part, prior to the brazing operation, in controlled conditions at a distance close to the contact zone. An independent claim is also included for a heat exchanger tube assembled by this method.
