Patent ID: 7460372

Claim:
A fixing means for a heat dissipater, capable of fixing the heat dissipater provided on a substrate, comprising: a base having a surface with a plurality of heat-dissipating pieces thereon, a center of the heat-dissipating piece having a sliding groove perpendicular to an orientation of the heat-dissipating pieces; a pair of connecting ends formed on the substrate; and a positioning frame having at least one transverse rod connected vertically with a pressing end, the pressing end being accommodated in the sliding groove to abut against the surface of the base, the transverse rod being located over the heat-dissipating pieces, to have both ends extended out of the heat-dissipating pieces to connect with the pair of connecting ends, respectively; wherein the positioning frame is connected to the connecting ends to generate a downward force, thereby to cause the pressing end to downwardly press the surface to fix the position of the base.
