Abstract

Tube à ailettes en forme de T. L'appareil qui permet de fabriquer un tel tube comprend un outil de roulage comportant un certain nombre de disques de roulage 8 pour former des ailettes normales à partir d'un tube lisse 1', des rouleaux d'entaillage 13 pour former des ailettes entaillées 2', un rouleau de cintrage 14 pour donner aux ailettes la forme d'un Y 2", et un rouleau d'aplatissement 11 pour donner aux ailettes la forme finale d'un T 2. Application aux échangeurs de chaleur.T-shaped finned tube. The apparatus for making such a tube comprises a rolling tool having a number of rolling discs 8 for forming normal fins from a smooth tube 1 ', rollers of 'notch 13 to form notched fins 2', a bending roller 14 to give the fins the shape of a Y 2 ", and a flattening roller 11 to give the fins the final shape of a T 2. Application to heat exchangers.
