The invention relates to a multi-chamber tube (1) produced from a flat strip (2) by welding along the longitudinal face, comprising two planar side faces (10, 11), two curved narrow edges (12, 13) and folded webs (7, 8, 9), made from the flat strip (2) which divide adjacent chambers (3, 4, 5, 6) and which are soldered to the inner wall of the tube (11'). According to the invention, the webs (7, 8, 9) are formed from only one side face (10) of the multi-chamber tube (1) and the other side face (11) has an essentially flat embodiment. |
