Abstract

Dans la présente invention, à la base de colliers d'ailette, il existe des creux qui sont formés dans la direction opposée à la direction d'élévation des colliers d'ailette. La forme de la section des creux à la base des colliers d'ailette est celle d'un arc de cercle qui suit à peu près la forme de la bride d'un bout du collier d'ailette adjacent, et de ce fait, les interstices sont réduits et on peut augmenter l'aire de contact entre un tuyau de transfert de chaleur et les colliers d'ailette. Par conséquent, la résistance thermique de contact est réduite, le transfert de chaleur entre le tuyau de transfert de chaleur et une ailette de transfert de chaleur est amélioré, et la capacité d'échange de chaleur est améliorée.
