1. A heat sink, comprising:
- a main body having a plurality of hollow fins and a base, each fin having a close end and an open end facing the base, and the fins and the base forming a closed room; and
a plurality of porous structures comprising a plurality of conductive portions, connective portions and heat-absorptive portions, wherein the conductive portions are continuously formed on the interior surfaces of the hollow fins, the heat-absorptive portions are formed on the base, and each connective portion is set between the neighboring conductive portions and connected to the heat-absorptive portions on the base to divide the closed room into a plurality of vapor chambers, and each connective portion comprises a plurality of holes for allowing vaporized fluid to pass therethrough.
