  • the suction member 211 of the present embodiment has a second slit 217 at a position corresponding to the first slit 50 of the plate fin 40. Then, when the suction member 211 that has attracted the plate fins 40 is lowered, the flat tube 30 is inserted into both the first slit 50 and the second slit 217. With such a configuration, the plate fin 40 can be satisfactorily held by the suction member 211 until the position where the flat tube 30 is completely inserted into the first slit 50.
  • the suction member 211 of the present embodiment has a protruding portion 216 that protrudes from the suction surface 213.
  • the suction member 211 that has attracted the plate fin 40 is lowered, the plate fin 40 is pushed by the protruding portion 216, so that both are suitably attached against the frictional force between the plate fin 40 and the flat tube 30. be able to.

Abstract

Un mode de réalisation de la présente invention concerne un procédé de fabrication d'un échangeur de chaleur qui comprend des première à troisième étapes. L'échangeur de chaleur est doté d'une pluralité de tuyaux plats qui sont disposés en réseau dans une première direction et qui sont plus longs dans une seconde direction et d'une pluralité d'ailettes de plaque qui sont disposées en réseau dans la deuxième direction et qui sont plus longues dans la première direction. Chacune des ailettes de plaque présente une pluralité de premières fentes qui sont ouvertes sur un côté le long de la première direction, et les tuyaux plats sont passés à travers les premières fentes des ailettes de plaque. Dans la première étape, la pluralité de tuyaux plats est disposée en réseau dans la première direction. Dans la deuxième étape, les ailettes de plaque sont attirées au moyen d'un élément d'aspiration. Dans la troisième étape, les ailettes de plaque attirées au moyen de l'élément d'aspiration et des tuyaux plats sont déplacées relativement dans une troisième direction, et les tuyaux plats sont positionnés dans les premières fentes des ailettes de plaque.
