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