Abstract
Disclosed are a method and an apparatus for controlling subrack fans. The method comprises: by installing multiple boards installed with high-power components in different areas of a subrack respectively, forming multiple heat dissipation air channels corresponding to the multiple boards respectively; installing a fan group comprising multiple heat dissipation fans on the subrack; dividing the fan group into multiple fan areas corresponding to the multiple heat dissipation air channels respectively, so that each fan area blows air to a corresponding board through a corresponding heat dissipation air channel; detecting temperature of each board and a rotating speed of a corresponding fan area in real time; adjusting the rotating speed of the fan area according to a detection result, so that the rotating speed of the fan area increases or decreases as the temperature of the corresponding board increases or decreases. Also disclosed is the apparatus for controlling subrack fans.
