Abstract

Echangeur de chaleur comprenant un faisceau d’échange thermique (3) entre au moins un premier fluide (F1) et un deuxième fluide (F2) composé par :- au moins deux éléments creux (31) présentant une première (33a) et une deuxième (33b) faces configurés pour former au moins un canal (35) présentant un centre (35c) et une périphérie (35p), - au moins une des première (33a) et/ou deuxième (33b) face d’au moins un élément creux (31) comporte une pluralité de protubérances (5) s’étendant dans un espace (37) pour la circulation du deuxième fluide (F2), et- les protubérances (5) sont conformées de manière à former une perte de charge plus concentrée au centre (35c) du canal (35) qu’au niveau de sa périphérie (35p).
