Patent ID: 7639504

Claim:
An electronic apparatus comprising: a circuit board with a heat generating electronic component disposed thereon; a heat sink; and a mounting device for mounting the heat sink onto the heat generating electronic component, the mounting device comprising a mounting frame, at least two clasping legs, and at least two resilient arms, the mounting frame comprising two first mounting arms and two second mounting arms disposed above the first mounting arms, the heat sink being enclosed in an inner space defined between the first mounting arms and the second mounting arms, the first mounting arms abutting on the circuit board, the at least two clasping legs each connecting with one of the second mounting arms of the mounting frame and being inserted through the circuit board to be attached to the circuit board, the at least two resilient arms each connecting with one of the second mounting arms of the mounting frame and exerting a downward resilient force on the heat sink toward the heat generating electronic component.
