Abstract
A heat exchanger tube, especially for a motor vehicle cooling radiator, comprises a body of oblong cross section defined by two major faces and two minor faces, an end portion of oblong cross section, again defined by two major faces and two minor faces, and a transition portion which joins the tube body to its end portion. The transition portion has two inclined faces which join together the major faces of the tube body and the major faces of the end portion, together with at least one curved face which joins together a minor face of the tube body and a minor face of the end portion, while also joining together the two major faces of the tube body.
