Definitions

  • the pair of roll-bonded plates is arranged between two first and second platen of a suitable press. Thereafter the outer ring shaped fluid circuit is inflated so that a pressure tight seal for the volume between the platen of the press is provided. Then the airtight volume on one side of the panel is pressurized and thereupon the inner fluid circuit pattern is inflated by air pressure supplied via a passageway serving as a delay line for inflating pressure.
  • the present process is very effective in the case where a U-shaped passage or V-shaped passage is formed by a portion of the first shunt passageway proximate to the curved passageway, the curved passageway and a portion of the second shunt passageway proximate to the curved passageway.
  • air having a pressure not lower than 80 kg/cm 2 to not higher than 130 kg/cm 2 is introduced into the nonbonded portions for inflation.
  • FIG. 1 shows a roll-bonded panel obtained by the production process of the invention.
  • the roll-bonded panel 1 is produced by printing a pattern corresponding to a fluid circuit on one surface of one of a pair of upper and lower aluminum plates with a parting agent (bonding preventing agent), roll-bonding the aluminum plates with the other aluminum plate superposed on the printed surface, and thereafter inflating nonbonded portions to a tubular form with air of high pressure introduced into these portions.
  • This embodiment has an inflated tube on one side thereof over the entire area.
  • the upper aluminum plate only is inflated, and the lower aluminum plate is flat.
  • the second embodiment differs from the first with respect to the following.
  • the first and second shunt passageways 14, 15 are not parallel to each other.
  • a V-shaped passage is formed by the portion of the first passageway 14 proximate to the curved passageway 16, the curved passageway 16 and the portion of the second passageway 15 proximate to the curved portion 16.
  • the first shunt passageway 14 is not straight and is held in communication with the main passage 13 by a straight passageway 14b connected to the passageway 14 approximately perpendicular thereto.

Claims (6)

  1. Procédé pour fabriquer un panneau laminé (1, 11) présentant un circuit de fluide, en gravant un dessin correspondant au circuit de fluide sur une surface d'une première plaque d'aluminium à l'aide d'un agent de séparation, en laminant ladite plaque d'aluminium avec une seconde plaque d'aluminium posée sur la surface gravée, puis en dilatant les parties non assemblées pour définir une forme tubulaire à l'aide d'une pression de fluide, caractérisé en ce que le circuit de fluide comprend un passage principal (3, 13) et au moins un passage de dérivation (2, 12) moins large que celui-ci, et le passage de dérivation (2, 12) comprend un premier passage de dérivation (4, 14) partant d'une partie du passage principal (3, 13), un second passage de dérivation (5, 15) partant d'une autre partie du passage principal (3, 13), et un passage courbe (6, 16) défini entre les deux passages de dérivation (4, 5) et (14, 15), étant précisé que la largeur (W2, W5) d'une première partie non assemblée à transformer en premier passage de dérivation (5, 15 ; 4, 14) est inférieure à la largeur (W1, W4) de la seconde partie non assemblée à transformer en second passage de dérivation (4, 14 ; 5, 15), et que la partie non assemblée à transformer en passage courbe (6, 16) a une largeur croissante de la première partie non assemblée à transformer en premier passage de dérivation (5, 15 ; 4, 14) vers la seconde partie non assemblée à transformer en second passage de dérivation (4, 14 ; 5, 15), et étant précisé que lors de la formation du passage de dérivation par dilatation, le passage de dérivation le plus large est formé en premier, puis le passage courbe, et enfin le passage de dérivation le moins large.
  2. Procédé de fabrication selon la revendication 1, caractérisé en ce que la différence entre la largeur (W1, W4) de la partie non assemblée à transformer en premier passage de dérivation (4, 14) et la largeur (W2, W5) de la partie non assemblée à transformer en second passage de dérivation (5, 15) n'est pas inférieure à 0,2 mm.

Procédé de fabrication selon la revendication 1 ou 2, caractérisé en ce qu'un passage en U est défini par une partie (4a) du premier passage de dérivation (4) située près du passage courbe (6), par ledit passage courbe (6) et par une partie (5a) du second passage de dérivation (5) située près du passage courbe (6).
  4. Procédé de fabrication selon la revendication 1 ou 2, caractérisé en ce qu'un passage en V est défini par une partie (14a) du premier passage de dérivation (14) située près du passage courbe (16), par ledit passage courbe (16) et par une partie (15a) du second passage de dérivation (15) située près du passage courbe (16).
  5. Procédé de fabrication selon l'une quelconque des revendications 1 à 4, caractérisé en ce que de l'air présentant une pression de 80 kg/cm2 minimum et de 130 kg/cm2 maximum est introduit dans les parties non assemblées, en vue de la dilatation.
  6. Panneau laminé (1, 11) formé à partir de deux plaques d'aluminium grâce à la gravure d'un dessin de circuit de fluide sur une surface d'une première plaque d'aluminium à l'aide d'un agent de séparation, au laminage des plaques d'aluminium, la seconde plaque étant posée sur la surface gravée, puis à la dilatation des parties non assemblées pour définir une forme tubulaire à l'aide d'une pression de fluide, caractérisé en ce que le circuit de fluide comprend un passage principal (3, 13) et au moins un passage de dérivation (2, 12) moins large que celui-ci, et le passage de dérivation (2, 12) comprend un premier passage de dérivation (4, 14) partant d'une partie du passage principal (3, 13), un second passage de dérivation (5, 15) partant d'une autre partie du passage principal (3, 13), et un passage courbe (6, 16) défini entre les deux passages de dérivation (4, 5) et (14, 15), étant précisé que la largeur d'une partie non assemblée à transformer en second passage de dérivation est inférieure à la largeur de l'autre partie non assemblée à transformer en premier passage de dérivation, et que le passage courbe a une largeur croissante.
