The radial rib plates and the fan blade body are integrally formed, so that the strength is improved, and the disc surface is prevented from deforming and damaging during high-speed rotation. The fan blades radially break up wind blown out from the fan blade body and enter a duct of the motor shell, so that the air speed is increased, and the heat dissipation performance is improved. The air inlet notch is shaped like an arc, so that the motor can work under the condition of positive and negative rotation.

Preferably, the disc surface is provided with symmetrical stabilizing fan blocks, and the air inlet gaps are symmetrically arranged along the central axis of the stabilizing fan blocks. The structure improves the stability of the fan and avoids the resonance of the fan caused by high-speed rotation.

Preferably, the radial rib plate has two ends that are thick and the middle that is thin in the axial height of the fan, and the radial rib plate has a circular arc shape that is symmetrical on both sides in the radial direction of the disk surface. The structure can direct the air flow blown by the radial ribs to be blown radially outward. The efficiency of the fan is improved.

Preferably, the disk surface and the fan blade body are integrally formed. The structure is convenient to produce and high in overall strength.

Preferably, the two ends of the stable fan block in the circumferential direction are respectively provided with a fan blade body.

Preferably, the radial ribs are rounded off everywhere. The structure avoids cutting and bruising the installer when installing.

Compared with the prior art, the beneficial effects of the utility model are that: (1) the cold air outside is fully sucked, and the heat dissipation efficiency is improved; (2) the air flow thrown out by centrifugation is increased, and the heat dissipation efficiency is improved.
