Abstract

Plaque de châssis et/ou plaque de pression pour un échangeur de chaleur à plaques, la plaque présentant des trous la traversant et prévus au moins pour un fluide échangeur de chaleur. Selon l'invention une ligne de paroi (8, 9; 42, 44) délimitant le trou (7; 41) est dirigée de manière à former un angle avec le plan (P) de la plaque différent de 90o.

Claims (7)

1. Plaque de châssis et/ou plaque de pression d'échangeur de chaleur àplaques comprenant au moins un trou traversant (7; 41) pour un agent d'échange de chaleur, caractérisée en ce que la paroi du trou présente une génératrice (8, 9; 42, 44) qui est inclinée par rapport au plan (P) de la plaque autour d'au moins une partie de la périphérie du trou.
2. Plaque de châssis et/ou plaque de pression d'échangeur de chaleur à plaques selon la revendication 1, dans laquelle le trou (7) comprend un axe central (C,) incliné en formant un angle différent de 90° par rapport au plan (P) de la plaque.
3. Plaque de châssis et/ou plaque de pression selon la revendication 1 ou 2, dans laquelle l'ouverture du trou (7) sur le côté externe de la plaque est plus proche de la périphérie de la plaque que ne l'est l'ouverture du trou sur le côté interne de la plaque.
4. Plaque de châssis et/ou plaque de pression selon l'une quelconque des revendications précédentes, dans laquelle sur une partie de la périphérie du trou la génératrice (8) forme un angle aigu avec une surface latérale (10) de la plaque (1) et sur une autre partie de la périphérie du trou, la génératrice forme un angle aigu par rapport à l'autre face latérale (11) de la plaque (1).
5. Plaque de châssis et/ou plaque de pression selon la revendication 1, 2 ou 3, dans laquelle sur une partie de la périphérie du trou (41 ), la génératrice (42) forme un angle aigu avec une face latérale (43) de la plaque (40), et sur une autre partie de la périphérie du trou qui est opposée à ladite première partie, la génératrice (44) forme un angle droit avec ladite face latérale (43).
6. Plaque de châssis et/ou plaque de pression selon la revendication 1, dans laquelle le trou (41) présente un axe central (C2) qui est à angle droit avec le plan (P) de la plaque (40).
7. Plaque de châssis et/ou plaque de pression selon la revendication 6, dans laquelle sur une partie de la périphérie du trou, la génératrice (42) forme un angle aigu avec une face latérale (43) de la plaque (40) et sur une autre partie de la périphérie du trou qui est opposée à ladite première partie, la génératrice (44) forme également un angle aigu avec ladite face latérale (43).
