A centrifugal fan system includes a housing, a plurality of blades, a ring wall and a base. The housing has at least one chassis arranged around the periphery of the housing, and the blades are arranged around the chassis.
Introduction to the fan
The ring wall extends and protrudes from the bottom surface of the chassis, and the housing, the blades and the ring wall constitute a rotor. The base is used to carry the rotor. The side wall of the base corresponds to the ring wall and surrounds and defines a receiving space.
