Abstract (en)
Flat tube for a heat exchanger, with two open ends defining its longitudinal direction, comprising a first wall (1) and a second wall (2) which are flat and parallel to each other, thereby delimiting the inner space of the tube. One of the lateral sides of the first wall (1) comprises a double-walled nose (4). The walls of said double-walled nose (4) contact each other along a contact section (5), and the lateral side (6) of the second wall (2) is bent to cover said double walled nose (4). Said walls of the nose (4) have equal lateral length.
