Patent ID: 8240363

Claim:
A heat dissipation apparatus comprising: a heat sink; a fan comprising a first lateral plate defining an airflow outlet, and a second lateral plate defining an airflow inlet wherein the first and second lateral plates are opposite to each other to sandwich an impeller of the fan therein, and a plurality of fixing holes is defined in the first lateral plate of the fan; and a fixing structure comprising: a base defining an airflow opening to allow air to flow between the heat sink and the fan; the first lateral plate of the fan rests on the base; two resilient side panels extending perpendicularly from two sides of the base, wherein the base and the side panels form an accommodating space to accommodate the fan therein; and a locking portion projects inward from each of the side panels, to engage with the second lateral plate of the fan to limit a movement of the fan perpendicular to the first lateral plate; and a plurality of fasteners each with a first end securing the base of the fixing structure to the heat sink, and a second end protruding into the accommodating space; wherein the second end is a bulge head, the first end is a threaded post extending from the bulge head, and the bulge head rests on the base and is accommodated in a corresponding fixing hole of the fan to limit a movement of the fan along a direction parallel with the first lateral plate.
