Patent ID: 7365978

Claim:
A heat dissipating device comprising: a heat sink comprising a chassis, a plate separate from the chassis and a plurality of fins extending between the chassis and the plate; a radiator comprising a base parallel to the fins; and heat-transfer pipes each comprising a heat-absorbing portion thermally positioned to the chassis, a heat-releasing portion thermally positioned to the plate and a heat-transfer portion disposed between the heat-absorbing portion and the heat-releasing portion, the heat-transfer portion thermally received in the base of the radiator; wherein the radiator comprises a plurality of metal flakes integrally formed from the base, for dissipating heat to ambient air; wherein the fins of the heat sink define channels therebetween for air convection, the metal flakes of the radiator define channels for air convection which are parallel to the channels between the fins; and wherein the base of the radiator defines grooves therein, the grooves extend from one end of the base to another end of the base, and the heat-transfer portions are received in the grooves.
