Patent ID: 8848363

Claim:
A heat dissipation system comprising: a computer case having a base plate, a side plate perpendicularly to the base plate and a back plate perpendicularly to the side plate; a motherboard, attached on the base plate, adjacent to the back plate; the motherboard has a heat sink mounted thereon, and a first fan positioned on the heat sink; a mass storage device mounted on the computer case beside the motherboard; the mass storage device is away from the back plate; a heat source positioned on the base plate beside the motherboard and a second fan positioned on the heat source, the heat source and the second fan are adjacent to the back plate; a plurality of first air inlet holes are defined on the side plate and aligned with the mass storage device; a plurality of second air inlet holes are defined on the side plate and aligned with the heat sink and the first fan; a first air path defined between the plurality of second air inlet holes and the back plate; the first air path is adapted to direct a first airflow toward the heat sink along a first direction and out of the computer case along a second direction, the second direction is perpendicular to the first direction; and a second air path defined between the plurality of first air inlet holes and the back plate; the second air path is adapted to direct a second airflow toward the mass storage device along the first direction and out of the computer case the second fan via the heat source along the second direction.
