Zusammenfassung:	The invention relates to a method for brazing a tube (1) of a heat exchanger, including the following steps: folding a metal strip (9) so as to form said tube (1) such that the tube (1) has at least one contact area between at least one edge (9a, 9b) of said strip (9) and the inner surface (23) of said tube (1) formed from said folded strip (9); applying a brazing flow (25) on a single surface (11) of said strip (9); and brazing the tube (1). The invention also relates to a tube (1) obtained by such a method, and to a heat exchanger including an array of such tubes (1).
