A stacked plate heat exchanger (10) including a plurality of stacked plate pairs (12), each plate pair including first and second plates having elongate central portions (34) surrounded by sealably joined edge portions with an elongate fluid passage (62) defined between the central portions. Each plate pair has spaced apart inlet (26) and outlet openings (28) in flow communication with the fluid passage, at least some of the plate pairs having a substantially planar air-side fin plate extending peripherally outward from the joined edge portions, the fin plates of the stacked plate pairs being spaced apart and substantially parallel to each other. The fluid passage may be arranged at an angle relative to air flow direction.

L'invention concerne un échangeur thermique (10) à lamelles superposées comprenant une pluralité de paires de lamelles superposées (12), chaque paire étant composée d'une première et d'une seconde lamelle pourvue d'une partie centrale (34) allongée et entourée de bords assemblés de manière étanche, un passage (62) fluidique allongé étant défini entre les parties centrales. Chaque paire de lamelles a des ouvertures d'entrée (26) et de sortie (28) espacées, en communication fluidique avec le passage fluidique. Quelques-unes au moins des paires de lamelles comportent une ailette sensiblement plane côté air, s'étendant périphériquement vers l'extérieur à partir du bord assemblé, ces ailettes étant espacées et pratiquement parallèles entre elles. Le passage fluidique peut être disposé en angle relativement à la direction du flux d'air.
