Abstract (en)
[origin: WO2006040118A1] The invention relates to a multi-channel flat tube (1) for a heat exchanger, especially for use in motor vehicles, which comprises a first lateral wall (14), a second lateral wall (15) substantially parallel to the first lateral wall (14), and at least one curved end section (17). A projection (9) from the material of the lateral wall (14, 15) is configured on at least one lateral wall (14, 15) on the inside facing a fluid flow in the interior of the flat tube (1). On the outside facing away from the fluid, the lateral wall (14, 15) is substantially planar in the area of the projection (9).
