Problems solved by technology

[0010] In view of this, the present invention provides a fan impeller, thereby solving the problem that the airflow generated by conventional fans tends to form turbulent flow near the hub, which seriously interferes with the discharge of the fan airflow, resulting in low heat dissipation efficiency of the fan

Embodiment Construction

[0033] Please refer to figure 1 with figure 2 , the fan impeller 100 disclosed in the first embodiment of the present invention includes a hub 110 , a plurality of first fan blades 120 and a plurality of second fan blades 130 . The hub 110 may be, but not limited to, a circular shell. A plurality of first fan blades 120 and a plurality of second fan blades 130 respectively surround the hub 110 and are arranged at intervals on the surface of the hub 110 in a staggered manner, wherein A plurality of first fan blades 120 and a plurality of second fan blades 130 can be arranged at equal intervals on the surface of the hub 110; The symmetrical (or evenly distributed) arrangement is arranged on the surface of the hub 110, which is not limited to the embodiments disclosed in the present invention.

[0034] In addition, the length of each first fan blade 120 is greater than the length of each second fan blade 130, so that the length of the first fan blade 120 protruding from the su...

Abstract

The invention relates to a fan impeller, comprising a hub, a plurality of first fan blades and a plurality of second fan blades, and the rotation radius of the first fan blades is greater than that of the second fan blades, so that the hub rotates through a plurality of The air volume driven by the first fan blade and multiple second fan blades can generate a uniform flow field around the hub, thereby preventing the pressure difference and turbulence of the airflow around the hub, and causing the fan impeller to rotate. The airflow has a fairly uniform flow field and smooth airflow discharge.

Description

[0001] 【Technical field】 [0002] The present invention relates to a fan impeller, in particular to an impeller of a cooling fan. [0003] 【Background technique】 [0004] With the rapid development of the electronic industry, most of the electronic products are developing towards the trend of light and thin, multi-functional and high computing speed. However, as the computing speed increases, electronic components such as central processing unit (CPU) or graphics processing unit (graphic processing unit (GPU)) used to perform data computing in electronic products often generate a large amount of waste heat. At this time, if the waste heat cannot be discharged from the electronic products in a timely manner, it will easily cause the operating temperature of the electronic components to be too high due to the accumulation of waste heat, which will greatly reduce the computing speed of the electronic components and seriously affect the operation of the electronic products. perfor...
