Abstract

L'invention concerne un échangeur de chaleur comprenant un premier collecteur, un second collecteur et une pluralité de segments de tube d'échange de chaleur reliant en couplage fluidique le premier et le second collecteur. Les segments de tube d'échange de chaleur comportent une courbure délimitant une première et une seconde dalle disposées à un angle l'une par rapport à l'autre. Chacun des segments de tube d'échange de chaleur comprend au moins un premier tube d'échange de chaleur et un second tube d'échange de chaleur au moins partiellement reliés par une bande s'étendant entre ceux-ci. Le premier tube d'échange de chaleur et le second tube d'échange de chaleur sont asymétriques de telle sorte qu'une surface d'écoulement en coupe transversale du premier tube d'échange de chaleur est différente de celle du second tube d'échange de chaleur. Un fluide s'écoule de manière séquentielle à travers les premiers tubes d'échange de chaleur de la première dalle et de la seconde dalle, puis à travers les seconds tubes d'échange de chaleur de la seconde dalle et de la première dalle.
