Patent ID: 8248783

Claim:
A heat dissipation system comprising: a computer case comprising a base plate and a back plate and a first side plate perpendicular to the base plate; wherein the first side plate defines a first air inlet therein and a first air outlet adjacent to the first air inlet; a heat sink positioned on a first heat source attached to the base plate; a first air channel is defined between the first heat source and the back plate; wherein the first air channel is in communication with the first air inlet; a first fan positioned in the computer case adjacent to a first side of the heat sink, the first fan is configured to generate airflow through the heat sink in such a manner that airflow flows from the computer case outside is sucked into the computer case via the first air inlet and the first air channel; and an air duct positioned in the computer case adjacent to a second side of the heat sink; wherein the heat sink is capable of heating air flowing from the first fan; the airflow heated by the heat sink is then blown out of the computer case by the first fan via the air duct and the first air outlet; a second heat source positioned on the base plate and a second air channel is defined between the first heat source and the second heat source; wherein the second air channel is parallel to the first air channel.
