Patent ID: 8437137

Claim:
A fixing mechanism for fixing a thermal module on a base, the fixing mechanism comprising: a U-shaped buckling component disposed on a side of the base and slidably buckling a thermal fin and a heat conducting block of the thermal module, the U-shaped buckling component comprising: two hook portions, each hook portion comprising a bottom and two lateral walls, the lateral walls being respectively disposed on opposite sides of the bottom, the thermal module sliding into the hook portion along a direction substantially perpendicular to a planer normal vector of the bottom, and the two hook portions simultaneously buckling opposite edges of the thermal module; a fixing component disposed on the other side of the base and connected to the U-shaped buckling component for clipping the base with the U-shaped buckling component, so as to constrain relative movement of the base and the thermal module; and at least one locking component for fixing the heat conducting block on an inner surface of the U-shaped buckling component.
