Patent ID: 7742296

Claim:
A computer comprising: a chassis comprising a rear wall at a rear side thereof and a sidewall at a lateral side thereof, the rear wall defining a plurality of inlet holes therein, and the sidewall defining a plurality of outlet holes therein; a motherboard being received in the chassis opposite to the sidewall, a heat sink is installed on the motherboard for dissipating heat generated by a processor mounted on the motherboard; an air guiding member being received in the chassis at a front side, for guiding air drawn into the chassis through the inlet holes toward the outlet holes; a fan for drawing the air from outside of the chassis through the inlet holes, and blowing the air out of the chassis through the outlet holes; and at least one extension card installed on the motherboard close to the rear wall of the chassis, and a storage module adjacent to the front side of the chassis away from the rear wall of the chassis and substantially aligned with the at least one extension card; wherein the air guiding member comprises an arc-shaped side plate, a first flat plate, and a second flat plate parallel to the first flat plate that define a first air passage aligning with the heat sink, for guiding the air that flows from the heat sink after cooling the processor to flow out of the chassis through the outlet holes; the air guiding member further comprising a third flat plate parallel to the second flat plate and arranged at a side of the second flat plate opposite to the first flat plate, the third flat plate, the side plate, and the second plate define a second air passage substantially parallel to the first air passage and aligning with the at least one extension card and the storage module, for guiding the air that flows from the at least one extension card and the storage module after cooling the at least one extension card and the storage module to flow out of the chassis through the outlet holes.
