Abstract
A centrifugal fan includes a plurality of blades, a housing for receiving the blades therein and an air guiding mechanism. The housing includes a top wall and a sidewall around the top wall. The sidewall defines a first air outlet and a second air outlet adjacent and perpendicular to the first air outlet. The air guiding mechanism is located between the first air outlet and the second air outlet. The air guiding mechanism includes an air guiding wall parallel to the second air outlet and an air partition wall extending inwardly from the air guiding wall towards the blades. The first air outlet is defined between the air partition wall and the sidewall. The second air outlet is defined between the air guiding wall and the sidewall of the housing.
