More Information
Summary:The invention discloses a centrifugal fan and an impeller of the centrifugal fan. The impeller comprises an impeller disc, and the impeller disc is provided with a front face facing the air inlet direction and a back face opposite to the front face. A reinforcing portion is arranged on the back face of the impeller disc so that deformation in rotation of the impeller is reduced, and when the impeller is designed, no large impeller top gaps need to be left; and air leakage caused by the too large impeller top gaps is avoided, and on the premise that safety is ensured, the efficiency of the impeller is improved.
