Claim:
A process for manufacturing a heat-dissipating device having a body and a plurality of blades with varied thickness and arranged around the body, wherein the body and the blades are integrally formed as a single unit, and there is an overlapped region formed between every two adjacent blades, the process comprising the steps of: providing a mold including a first mold portion and a second mold portion, wherein the first mold portion is engaged with the second mold portion along a separating line between the first mold portion and the second mold portion, the separating line passing through a largest cross section in thickness of each blade of the heat-dissipating device; applying a desired material into a space defined in the mold for forming the heat-dissipating device therein so as to execute a forming step of the heat-dissipating device; and stripping the first mold portion and the second mold portion along an inclined direction of blades, thereby fabricating the heat-dissipating device.
