Abstract

L'invention concerne un échangeur de chaleur (A) comprenant une succession de tubes (6) se trouvant côte à côte, chacun ayant un noyau tubulaire (20) et des ailettes circulaires (22) entourant le noyau. De plus, chaque tube a une paire de chicanes (26) attachées aux extrémités de ses ailettes et s'étendant généralement de manière axiale le long des ailettes. Les chicanes reposent le long des côtés en aval des ailettes et dévient l'écoulement du fluide vers la face en aval du noyau de manière à améliorer le transfert de chaleur entre ce fluide et le noyau et les ailettes.
