Abstract

L'invention concerne une ailette (2) ayant une partie découpe en forme de U (21a) pour ajuster un tube plat (1) et des collerettes d'ailette (22a) s'élevant en diagonale depuis les sections de bord de la partie découpe (21a). La largeur d'extrémité d'ouverture (W2) de la partie découpe (21a) est formée de manière à être supérieure à la largeur de profil (W1) du tube plat (1). Les collerettes d'ailette (22) ont une partie surface inclinée de collerette d'ailette (22a) s'élevant depuis une section de bord de la partie découpe (21a) de manière à être inclinée par rapport au plan d'ailette et une partie surface d'extrémité de collerette d'ailette (22b) se courbant depuis la section d'extrémité de la partie surface inclinée de collerette d'ailette (22a) et venant en contact de surface avec la surface extérieure du tube plat (1). Les parties surfaces d'extrémité de collerette d'ailette (22b) sont en contact de surface avec la surface extérieure du tube plat (1).
