HEAT DISSIPATION DEVICE AND CENTRIFUGAL FAN THEREOF

摘要

A centrifugal fan includes a housing and a plurality of blades received in the housing. The housing includes a base wall and a sidewall surrounding the base wall. The sidewall defines a first air outlet and a second air outlet adjacent to the first air outlet. An elongated air guiding plate is located between the first air outlet and the second air outlet. The air guiding plate includes an outer end away from the blades and an inner end adjacent to the blades. A height of the inner end of the air guiding plate in an axial direction of the centrifugal fan is smaller than a height of the outer end of the air guiding plate.
