Patent ID: 7457119

Claim:
A heatsink module, used for dissipating heat generated by a heat generating component, the heatsink module comprising: a heat pipe having a first end connected to the heat generating component, for conducting the heat of the heat generating component to a second end of the heat pipe; a heatsink fin assembly, connected to the second end of the heat pipe, which is opposite to the heat generating component, for conducting the heat of the heat pipe away therefrom; a fan blade motor set, for generating an airflow passing through the heatsink fin assembly to dissipate the heat from the heatsink fin assembly; a fan shell, accommodating the heatsink fin assembly and the fan blade motor set, and having a plurality of buckling components, each buckling component including: a buckling hole disposed at a side edge of said fan shell; a fastening plate extending outward and having an inside surface facing a respective buckling hole; and an auxiliary buckling hole disposed in the inside surface of a respective fastening plate; and an external cover, covering the fan shell, and having a plurality of buckles, each buckle having a plate corresponding to, and being receivable within, a respective one of the buckling components, wherein each plate extends downward from a rim of the external cover and has a bump and an auxiliary bump, the bump being formed on a side of the plate corresponding to the buckling hole, the auxiliary bump being formed on another side of the plate corresponding to the auxiliary buckling hole, the bump being receivable in the buckling hole, and the auxiliary bump being receivable in the auxiliary buckling hole, whereby the external cover is buckled to the fan shell.
