Abstract
A composite thin-shape heat dissipation apparatus is characterized in that the apparatus comprises a hard thermal conductive substrate, at least one graphite paper heat dissipation layer and several area expansion heat dissipation portions, wherein the graphite paper heat dissipation layer is combined with a heat dissipation surface of the hard thermal conductive substrate, is formed by a graphite paper material and is in a planar shape and possesses a planar thermal conduction portion; the several area expansion heat dissipation portions are integratedly formed on the graphite paper heat dissipation layer structure, are in an interval arrangement distribution shape and form an area expansion form which is convexly stretched outwardly. Structure characteristics that a graphite paper material is soft; weight is light and a thin type is possessed are used so that an overall structure approaches the thin type. Simultaneously, the expansion heat dissipation portions are in the area expansion form which is convexly stretched outwardly so that the apparatus can satisfy a thin type structure need and a good heat dissipation effect is kept. The area expansion heat dissipation portions are formed through directly partial bending by using pliability of the graphite paper material. Compared to manufacturing of a metal material, the manufacturing of heat dissipation portions is easy and convenient. Convenience of the manufacturing can be greatly increased and manufacturing and processing cost is reduced.
