Patent attributes
A heat sink includes a metallic heat conducting layer, a non-metallic heatsink layer combined with the metallic heat conducting layer and having a porous structure, and a hollow receiving space defined between the metallic heat conducting layer and the non-metallic heatsink layer. Thus, the heat produced by a heat source is conducted quickly and distributed evenly on the metallic heat conducting layer to form an evenly heat conducting effect, while the hollow receiving space has a heat convection effect to quickly transfer the heat on the metallic heat conducting layer to the non-metallic heatsink layer which produces a heatsink effect to dissipate the heat so that the heat is dissipated quickly by provision of the metallic heat conducting layer, the hollow receiving space and the non-metallic heatsink layer.
