Patent ID: 7564688

Claim:
A heat dissipation assembly adapted for dissipating heat generated by an electronic component mounted on a printed circuit board, the heat dissipation assembly comprising: a heat sink assembly for contacting the electronic component; a pair of retaining members fixed on two lateral sides of a top portion of the heat sink assembly; a pair of arms pivotably attached to the pair of retaining members, respectively; and an operating member pivotably secured to the pair of retaining members, wherein the operating member comprises a handle, a first cam formed slantwise at each of two distal ends of the handle, and a second cam formed outwardly from the first cam, wherein when the operating member is rotated from a vertical orientation to a horizontal orientation, the arms are activated by the operating member to rotate inwardly towards the heat sink assembly, and engage with the heat sink assembly, thus securing the heat dissipation assembly on the electronic component.
