The fan frame is provided with a cover plate part; the motor stator group is arranged inside the fan frame; the impeller is combined with the motor stator set and has a radial rotating range; the cover plate part of the fan frame is provided with an airflow guide area and an airflow amplification area, the airflow guide area is positioned in the radial rotating range of the fan wheel, and the airflow amplification area is positioned in the area outside the radial rotating range of the fan wheel. Therefore, when the centrifugal fan is arranged in an electronic product, the design of the airflow amplification area can be utilized to effectively increase the lateral air intake of the centrifugal fan. However, the fan is regular in shape in the longitudinal direction, and the space occupied by the rotation of the impeller is small, which is disadvantageous to the performance of the fan.

To solve the problems in the related art, a heat dissipation fan suitable for a thin electronic product is proposed.
