Abstract

La divulgation concerne une ailette perfectionnée d'échange de chaleur destinée à un refroidisseur d'air du type à pièce de manchon, l'ailette perfectionnée d'échange de chaleur comprenant un substrat ondulé triangulaire (1). Une pluralité de trous (2) de tuyau sont répartis de manière uniforme dans le substrat (1), et des saillies de perturbation d'écoulement (3) sont disposées au niveau de certaines positions, entourant les trous (2) de tuyau, sur une face d'extrémité d'un côté du substrat (1), afin de résoudre le problème d'une ailette existante n'ayant pas d'effet de perturbation d'écoulement sur des agents, ce qui empêche qu'un coefficient de transfert de chaleur soit élevé, et l'ailette de l'invention satisfait ainsi aux exigences d'une haute conductivité thermique et d'une haute fiabilité.
