CA 2119344
A heat exchanger is disclosed, which comprises: a plurality of tubes each having a U-shaped portion and arranged in a plurality of parallel bending planes, each bending plane containing a plurality of tubes of the same nominal outer diameter and of differing bending radius, the variation of the outer diameter of the tubes in at least one of the bending planes measured in a direction perpendicular to the bending planes being at most 0.1 mm; and an antivibration bar disposed between two of the bending planes.
Échangeur thermique comprenant de nombreux tubes constitués d'une partie en U, placés sur de nombreux plans de courbure parallèles, et d'une barre antivibrations placée entre deux des plans. Chaque plan contient de nombreux tubes de même diamètre extérieur nominal et de rayon de courbure différent, la variation du diamètre extérieur des tubes dans au moins un des plans, mesurée dans une direction perpendiculaire aux plans, ne dépassant pas 0,1 mm.
