CA 2400982

A fluid cooling device (100), and a method for manufacturing the fluid cooling device includes a plurality of cold plate members (102), each having a plurality of imperforate plate portions (104) and perforated portions (106) arranged in a line; and at least one connector (108) for connecting the plate portions together at one end thereof. The cold plate members (102) are arranged in a stack, wherein respective plate portions (104) of each cold plate (102) are in registration with perforate portions (104) formed in its adjacent cold plate member (102) in the stack. The method for manufacturing the fluid cooling device (100) includes forming a plurality of cold plate member (102) from a planar metal tape or thin layer stock; positioning the cold plate member (102) relative to each other so that the respective imperforate plate portions (104) of each cold plate member (102) are in registration with the perforate portions (106) formed in adjacent cold plate members (102); and joining each cold plate member (102) with the adjacent cold plate members.

L'invention concerne un dispositif de refroidissement par liquide (100), et un procédé permettant de fabriquer ce dispositif. Le dispositif de refroidissement par liquide comprend une pluralité de plaques de refroidissement (102), présentant chacune une pluralité de portions de plaque imperforées (104) et de portions de plaque perforées (106) disposées en ligne; et, au moins, un connecteur (108) permettant de relier les portions de plaque entre elles par l'une de leurs extrémités. Les plaques de refroidissement (102) sont empilées; chaque portion de plaque (104) de chaque plaque de refroidissement (102) concordant avec les portions perforées (106) ménagées dans les plaques de refroidissement (102) adjacentes empilées. Le procédé de fabrication d'un tel dispositif (100) consiste à former une pluralité de plaques de refroidissement (102) à partir d'un ruban métallique plat ou d'une pièce à usiner à couches minces; à disposer les plaques de refroidissement (102) l'une par rapport à l'autre de sorte que les portions imperforées (104) respectives de chaque plaque de refroidissement (102) concordent avec les portions perforées (106) ménagées dans les plaques de refroidissement (102) adjacentes; puis à assembler chaque plaque de refroidissement (102) aux plaques de refroidissement adjacentes.
