Title (EN) THERMAL DIFFUSION APPARATUS
(FR) APPAREIL DE DIFFUSION THERMIQUE
Abstract: front page image
(EN)An apparatus for operably conveying heat away from a heat source includes a thermally conductive substrate having a thickness defining a planar boundary thereof, and an insert portion disposed in the substrate and being positioned so as not to extend beyond the planar boundary. The insert portion is a material having a thermal conductivity value of at least 1.5 times that of the substrate material along at least two axial directions, with one of such axial directions extending substantially perpendicularly to first and second opposed sides of the substrate.
(FR)L'invention concerne un appareil servant à transporter et éloigner de manière fonctionnelle la chaleur d'une source de chaleur. L'appareil comprend un substrat thermoconducteur dont l'épaisseur délimite une limite planaire du substrat; et une partie rapportée disposée dans le substrat et positionnée de façon à ne pas s'étendre au-delà de la limite planaire. La partie rapportée est un matériau dont la valeur de la conductivité thermique est au moins 1,5 fois celle du matériau du substrat, le long d'au moins deux directions axiales, l'une desdites directions axiales s'étendant de manière sensiblement perpendiculaire à un premier et un second côtés opposés du substrat.
