Patent ID: 8922990

Claim:
A device comprising: a device housing having a top wall and an end wall adjacent to the top wall, the end wall including an exhaust vent for allowing exhaust air to leave the housing; a fin pack including: a fin pack housing having four sidewalls, including a first sidewall opposite a second sidewall, a third sidewall between the first and second sidewalls, the third sidewall being opposite a fourth sidewall, the fourth sidewall between the first and second sidewalls; a set of fins extending from the first sidewall towards the second sidewall, the set of fins being arranged between the third and fourth sidewalls; an entrance at a first end of the fin pack housing and an exit at a second end of the housing opposite the entrance, the exit being oriented towards the exhaust vent and spaced a predetermined distance from the exhaust vent, the pre-determined distance from the exhaust vent is such that an equation, a+b≧c is satisfied, where a is a total cross sectional area of the exhaust vent between an outer edge of the fin pack and the end wall, where b is a usable cross sectional area of the exhaust vent, and where c is a total cross sectional exhaust area of the fin pack, wherein the fins begin at the entrance and terminate at the exit such that during operation of the fin pack, air flows into the fin pack at the entrance, through the fins, and out of the fin pack at the exit; and a blade extending from the first sidewall past the exit and towards the exhaust vent and from the third sidewall to the fourth sidewall, the blade having a generally rectangular shape with three exposed edges all in a same plane as the first sidewall; wherein the fin pack is positioned in the device housing to allow heat generated by a processor to move through the fin pack from the entrance through the fins and out the exit; and wherein the blade is configured to prevent a hot spot from forming on the top wall along a second plane through a center line of the fin pack.
