Patent ID: 8708558

Claim:
A temperature detecting apparatus for adjusting direction of airflow from a fan according to status of heat sources in a chassis, the chassis comprising a first portion and a second portion, the temperature detecting apparatus comprising: a detection module capable of detecting temperatures of the heat sources, and converting the detected temperatures to voltage signals; a comparison module capable of receiving the voltage signals, and comparing the voltage signals with a reference voltage to output control signals; a control module capable of receiving the control signals and turning on according to the control signals; and a driver module comprising a motor, the motor capable of driving a plurality of air guiding fins rotating thereon; wherein the control module controls a current to flow through the motor in a clockwise direction or a counterclockwise direction; when the current flows through the motor in the counterclockwise direction, the motor drives the air guiding fins to turn toward a first direction, and the guiding fins guide air to flow to the heat sources at the first portion of the chassis; when the current flows through the motor in the clockwise direction, the motor drives the air guiding fins to turn toward a second direction, and the guiding fins guide air to flow to the heat sources at the second portion of the chassis.
