Abstract

L'invention concerne un échangeur de chaleur du type à plaques et ailettes brasées comprenant une pluralité de plaques agencées parallèlement entre elles de façon à définir une série de passages pour l'écoulement d'un premier fluide à mettre en relation d'échange thermique avec au moins un deuxième fluide, au moins un passage (33) étant formé entre une première et une deuxième plaque (6, 7) et comprenant au moins un premier élément intercalaire (221) et un deuxième élément intercalaire (222). Selon l'invention, le premier et le deuxième éléments intercalaires (221, 222) comprennent au moins une texturation de surface (23) sous la forme d'une structure poreuse ou de reliefs formés sur des surfaces du premier et du deuxième éléments intercalaires (221, 222), au moins un premier ensemble ailette ou jambe d'onde (123) et au moins un deuxième ensemble une ailette ou jambe d'onde (223), au moins une ailette ou jambes d'onde (123, 223) présentant la texturation de surface (23), au moins une première portion d'assemblage (121) du premier élément (221) étant exempte de texturation de surface (23) sur au moins celle (121a) des surfaces de la première paire orientée du côté de la première plaque (6) et au moins une deuxième portion d'assemblage (321) du deuxième élément (222) étant exempte de texturation de surface (23) sur au moins celle (321b) des surfaces de la deuxième paire orientée du côté de la deuxième plaque (7).The invention relates to a heat exchanger of the brazed plate and fin type comprising a plurality of plates arranged parallel to one another so as to define a series of passages for the flow of a first fluid to be placed in a heat exchange relationship with one another. at least a second fluid, at least one passage (33) being formed between a first and a second plate (6, 7) and comprising at least a first intermediate element (221) and a second intermediate element (222). According to the invention, the first and the second intermediate elements (221, 222) comprise at least one surface texturing (23) in the form of a porous structure or of reliefs formed on surfaces of the first and second intermediate elements ( 221, 222), at least a first fin or wave leg assembly (123) and at least a second set of a fin or wave leg (223), at least one fin or wave leg (123, 223) exhibiting the surface texturing (23), at least a first assembly portion (121) of the first member (221) being free of surface texturing (23) on at least that (121a) of the surfaces of the first oriented pair of the side of the first plate (6) and at least a second assembly portion (321) of the second member (222) being free of surface texturing (23) on at least that (321b) of the surfaces of the second oriented pair of the side of the second plate (7).
