The heat exchanger tube comprises a cylindrical, smooth walled outer tube (1) of steel into which a profiled insert (2) of aluminium is inserted. The profiled insert is constituted by two half shells (3,4) which engage in one another at their longitudinal edges with groove- shaped recesses (7) and rib-like projections (8). Both half shells (3,4) carry longitudinally extending ribs (5) on their internal surface which are so aligned that each half shell with its ribs constitutes a profile which is open on one side.
L'invention concerne un tube échangeur de chaleur qui comprend un tube extérieur (1) cylindrique à paroi lisse, en acier, dans lequel est inséré un profilé (2) en aluminium. Ce profilé se compose de deux demi-coques (3, 4) qui s'emboîtent au niveau de leurs bords longitudinaux par le biais de cavités (7) se présentant sous forme de rainures et de parties saillantes (8) se présentant sous forme de nervures. Les deux demi-coques (3, 4) comportent des ailettes (5) longitudinales sur leur face intérieure, orientées de manière à ce que chaque demi-coque constitue, de par ses ailettes, un profilé ouvert d'un côté.
