Heat sink having enhanced heat dissipation capacity

摘要

A heat sink includes a metallic heat conducting layer (1), a non-metallic heatsink layer (2) combined with the metallic heat conducting layer and having a porous structure, and a hollow receiving space (4) defined between the metallic heat conducting layer (1) and the non-metallic heatsink layer (2). Thus, the heat produced by a heat source (A) is conducted quickly and distributed evenly on the metallic heat conducting layer to create an evenly heat conducting effect, while the hollow receiving space (4) has a heat convection effect to quickly transfer the heat from the metallic heat conducting layer (1) to the non-metallic heatsink layer (2) which produces a heatsink effect to dissipate the heat so that the heat is dissipated quickly by provision of the metallic heat conducting layer (1), the hollow receiving space (4) and the non-metallic heatsink layer (2).
