Problems solved by technology

[0002] The use of fans is closely related and inseparable to people. For a known cooling fan, please refer to Figure 7 As shown, the cooling fan 200 includes a base 210, a fan wheel 220, an upper cover 230, a stator 240 and a bearing 250, the bearing 250 is arranged on the machine body 210, and the fan wheel 220 has a plurality of fan blades 221 and a shaft 222, the shaft 222 is pivoted on the bearing 250, the fan wheel 220 can be driven by the stator 240, please refer to Figure 8 As shown, the heat dissipation fan 200 is used upside down, and the fan wheel 220 will be displaced downward due to the influence of gravity. When the fan wheel 220 is driven to rotate, the fan wheel 220 will shake, causing the heat dissipation fan 200 to generate Noise may cause improper friction between the shaft rod 222 and the bearing 250, thereby reducing the cooling effect and rotation stability of the cooling fan 200

Abstract

The invention discloses a cooling fan which comprises a frame and a fan wheel. The frame comprises a base, the fan wheel is arranged on the base and is provided with multiple first blades, multiple second blades and multiple wing-shaped ribs, the first blades and the second blades are arranged in a mutually-spaced manner, and the wing-shaped ribs are connected with the first blades and the second blades and form a wing-shaped ring. The wing-shaped ring formed by the wing-shaped ribs can effectively improve rotating stability of the cooling fan.

Description

technical field [0001] The invention relates to a fan, in particular to a cooling fan. Background technique [0002] The use of fans is closely related and inseparable to people. For a known cooling fan, please refer to Figure 7 As shown, the cooling fan 200 includes a base 210, a fan wheel 220, an upper cover 230, a stator 240 and a bearing 250, the bearing 250 is arranged on the machine body 210, and the fan wheel 220 has a plurality of fan blades 221 and a shaft 222, the shaft 222 is pivoted on the bearing 250, the fan wheel 220 can be driven by the stator 240, please refer to Figure 8 As shown, the heat dissipation fan 200 is used upside down, and the fan wheel 220 will be displaced downward due to the influence of gravity. When the fan wheel 220 is driven to rotate, the fan wheel 220 will shake, causing the heat dissipation fan 200 to generate Noise may cause undue friction between the shaft 222 and the bearing 250 , thus reducing the cooling effect and rotation stab...
