Patent ID: 7656664

Claim:
An airflow direction controlling apparatus for selectively directing airflow of a fan toward one of at least two electronic components in danger of overheating in a computer, comprising: a frame being arranged near an outlet of the fan, wherein the frame comprises two opposite side walls; at least one blade pivotably mounted to the frame and driven by a motor comprising a pinion; wherein each of the at least one blade comprises a pivot at the bottom thereof, and the pivot of each of the at least one blade engages in the two opposite side walls of the frame; wherein one end of the pivot has a pinion, and the pinion of the motor and the pinion of the pivot are meshed with a pinion rack; at least two thermal sensors configured for detecting temperatures of the at least two electronic components in the computer; and a control module electronically connected to the at least two sensors and the motor, the control module receiving the detected temperatures from the sensors, determining if an electronic component is in danger of overheating, and controlling the motor to pivot the at least one blade around the pivot thereof via the pinion rack to a desired position where airflow of the fan blows toward the electronic component in danger of overheating to quickly dissipate the heat generated by the electronic component.
