Title (EN) HEAT SINK MADE FROM LONGER AND SHORTER GRAPHITE SHEETS
(FR) DISSIPATEUR THERMIQUE CONSTITUE DE FEUILLES DE GRAPHITE PLUS OU MOINS LONGUES
Abstract: front page image
(EN)A heat sink apparatus (10) is constructed from alternating longer and shorter sheets of graphite material (14), (16) sandwiched together such that the longer sheets (14) extend beyond the shorter sheets (16) to define fins. The directions of higher thermal conductivity of the anisotropic graphite material are oriented in the plane of the sheet. The longer (14) and shorter (16) sheets have base ends (18) aligned together to define a generally planar base surface (20) for engaging an electronic device (12) to be cooled.
(FR)L'invention concerne un dispositif dissipateur thermique produit en alternant des feuilles plus longues et des feuilles plus courtes de matériau graphite, mises en sandwich de sorte que les feuilles plus longues s'étendent au-delà des feuilles plus courtes pour définir des ailettes. Les directions de plus grande conductivité thermique du matériau graphite anisotrope sont orientées dans le plan de la feuille. Les feuilles plus longues et les feuilles moins longues ont des extrémités de base alignées entre elles afin de définir une surface de base pratiquement plane pour la mise en place d'un dispositif électronique à refroidir.
