Patent ID: 7787247

Claim:
An apparatus with improved heat dissipation, comprising: a circuit board with at least one heat generating component affixed thereto; and a fan and carrier therefor including a heat sink plate and means forming an airflow passageway over a surface thereof, said heat sink plate having a portion thereof along said passageway and downstream of said fan thermally coupled to said heat generating component on one side of said heat sink plate opposite a second side thereof forming said surface, said heat sink plate having means forming at least one slot therein proximate a bounding edge of said portion, said fan being adapted to direct an airflow through said passageway and over said surface, said slot and said portion; wherein thermal energy generated by said heat generating component is transferred to said heat sink plate and ultimately removed therefrom by said airflow, and wherein said airflow passing through said passageway and over said slot reduces the atmospheric pressure over said slot and thereby induces a secondary airflow through said slot from said one side of said heat sink plate to said second side during operation of said fan, thereby enhancing removal of thermal energy from said heat generating component.
