Patent ID: 6935419

Claim:
A heat dissipating apparatus comprising: a heat sink device having a plurality of cooling fins coupled thereto, said heat sink device adapted to be thermally coupled with a heat source, said plurality of cooling fins adapted to dissipate heat generated by said heat sources and wherein said plurality of cooling fins are disposed in a first region and a second region, wherein said plurality of cooling fins in said first region generate less resistance to said airflow than is generated by said plurality of cooling fins in said second region, an air duct coupled with said heat sink device, said air duct for directing an airflow to said cooling fins to increase dissipation of said heat wherein said air duct directs said airflow through said first region of said plurality of cooling fins, and subsequently through said second region of said plurality of cooling fins; and a plurality of upstream fins coupled with said air duct, said plurality of upstream fins upstream of said plurality of cooling fins, said plurality of upstream fins not connected to said heat sink and for providing direction to said airflow with respect to said plurality of cooling fins.
