Abstract

The invention discloses an axial flow wind wheel and a fan with the axial flow wind wheel. The axial flow wind wheel comprises a wheel hub and a plurality of blades; the blades are arranged on the wheel hub; a flow guide rib is arranged on at least one of the plurality of the blades; the flow guide rib is formed on a force absorbing surface of the blade. According to the axial flow wind wheel of the embodiment of the invention, the air flow separation on the force absorbing surface of the blade can be reduced, the air supply amount can be improved, and the air supply noise can be reduced.

Description

technical field [0001] The present invention relates to the technical field of ventilation equipment, and more specifically, relates to an axial-flow wind wheel and a fan having the same. Background technique [0002] The suction surface of the axial-flow wind wheel in the related art is prone to airflow separation, which generates separation noise, thereby affecting the performance of the fan, reducing the service life of the fan, and the generated noise will affect the quality of life of users. Contents of the invention [0003] The invention aims at at least solving the technical problems of airflow separation and high air supply noise in the prior art. For this reason, the present invention proposes an axial flow wind wheel, which can reduce air separation and reduce air supply noise. [0004] The invention also proposes a fan with the above-mentioned axial-flow fan wheel. [0005] The axial wind rotor according to the embodiment of the first aspect of the present in...
