Abstract

A centrifugal blower comprises a housing, a cover plate, and a impeller. The housing has an inner space, a radial outlet, an annular wall, and at least one auxiliary radial inlets. The cover plate has an axial inlet. The impeller is rotatably mounted in the inner space of the housing. The auxiliary radial inlets are formed on the annular wall, and dimensioned different from the radial outlet. Thus, when the impeller is rotated, the axial inlet of the cover plate and the auxiliary radial inlets of the housing can suck airflow along both of axial and radial direction, respectively.
