Abstract

L'invention concerne un conduit échangeur de chaleur possédant une efficacité d'échange de chaleur améliorée. Ce conduit comporte une ferrure interne possédant de multiples parties de projection en contact avec la paroi interne du conduit, permettant ainsi une transmission de la chaleur du fluide de l'intérieur vers l'extérieur du conduit via cette. Ainsi, une ferrure interne installée à l'intérieur du conduit permet de réduire les coûts de fabrication, d'améliorer l'efficacité d'échange de chaleur, et d'éliminer avec facilité des impuretés de fluide accumulées à l'intérieur du conduit.
