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).
