Patent ID: 7679912

Claim:
A heat sink assembly adapted for dissipating heat generated by an electronic heat-generating device, the heat sink assembly comprising: a first heat dissipating plate having a top surface and a bottom surface thermally contacting the heat generating electronic device; a second heat dissipating plate having a first surface and a second surface opposite the first surface; a heat pipe module sandwiched between the top surface of the first heat dissipating plate and the first surface of the second heat dissipating plate, the heat pipe module comprising a first heat pipe and a second heat pipe, the first and second heat pipes cooperatively defining an enclosed-space, wherein the enclosed-space is enclosed by the top surface of the first heat dissipating plate and the first surface of the second heat dissipating plate; and a plurality of through holes communicating with the enclosed-space being defined in at least one of the first heat dissipating plate and the second heat dissipating plate.
