CA 2673014
The invention relates to a heat exchanger (1) including a set of plates (10) defining between them circuits (2, 3) for a fluid flowing alternatively via seals (4) mounted between each couple of two adjacent plates, each plates including at least one guiding cut (5) formed at least at one of the ends thereof for guiding each plate inside a frame (6). According to the invention, the exchanger is characterised in that it further comprises between each couple of two adjacent plates and in the vicinity of the guiding cut (5) at least one strut (7) to be compressed and in contact with the two adjacent plates, each strut (7) having before compression a thickness at least equal to that of the seal.
L'invention concerne un échangeur thermique (1) comportant un ensemble de plaques (10) définissant entre elles des circuits (2,3) de fluide circulant en alternance au moyen de joints d'étanchéité (4) rapportés entre chaque couple de deux plaques adjacentes, chaque plaque comprenant au moins une découpe de guidage (5) ménagée au niveau d'au moins une de ses extrémités et permettant de guider chaque plaque (10) à l'intérieur d'un châssis (6). Selon cette invention, cet échangeur est remarquable en ce qu'il comprend également entre chaque couple de deux plaques adjacentes, et à proximité de la découpe de guidage (5), au moins une entretoise (7) destinée à être comprimée et agencée au contact des deux plaques adjacentes, chaque entretoise (7) présentant, avant compression, une épaisseur au moins égale à celle du joint d'étanchéité.
