Description

Fan structure

This creation is about a cooling fan, especially a fan structure.

With the advancement of technology, the functions of 3C products such as computers are becoming more diverse, and the heat generated by the internal electronic components is also more impressive. If the temperature of electronic components is too high, the performance and stability during operation will be affected. Most electronic components require heat sinking to ensure proper operation of the electronic components. Among them, the cooling fan is a common heat sink.

However, the conventional cooling fan mainly includes a hub and a plurality of blades disposed on the hub and encircling each other in a circle, but the above-mentioned cooling fan has problems such as insufficient airflow and insufficient wind pressure, thereby causing poor heat dissipation efficiency. It is not possible to effectively dissipate heat in densely packed electronic component areas or other high heat accumulation areas.

In view of this, the present creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the research, and has become the object of improvement of the present inventors.

The purpose of this creation is to provide a fan structure in which the shape of each blade is in the shape of a bird wing, and the blade of the bird wing shape has an effect of suppressing detachment of the vortex at the center portion, thereby eliminating the original prevention. Stripping the resulting countercurrent to achieve the advantage that the fan structure has increased static pressure and air volume.

In order to achieve the above object, the present invention provides a fan structure comprising: a hub; and a plurality of blades extending outwardly from an outer circumference of the hub, each of the blades having a shape of a bird wing.

The detailed description and technical content of the present invention will be described below in conjunction with the drawings, but the drawings are for illustrative purposes only and are not intended to limit the present invention.

Referring to FIG. 1 to FIG. 6 , the present invention provides a fan structure. The fan structure 10 mainly includes a hub 1 and a plurality of blades 2 .

As shown in FIGS. 1 to 2, the hub 1 is mounted on the holder 3, and the hub 1 is rotatable relative to the holder 3.

As shown in FIGS. 1 to 6, a plurality of blades 2 are formed to extend outward from the outer periphery of the hub 1, and each of the blades 2 has a bird wing shape, and the plurality of blades 2 are equidistantly arranged with each other.

As described in detail below, each of the blades 2 has a top surface 21 and a bottom surface 22, and the top surface 21 protrudes outwardly with a plurality of wing-like projections 23 arranged side by side, and an air flow is formed between the plurality of wing-like projections 23 In the channel 24, the bottom surface 22 protrudes outwardly with a plurality of wing-like projections 23' arranged in parallel, and an air flow passage 24' is formed between the plurality of wing-like projections 23'.

In addition, each of the blades 2 has a top edge 25, a bottom edge 26 and a side edge 27, and the top edge 25 is a curved edge. One side of the plurality of wing-like projections 23, 23' corresponds to the bottom edge 26. The side edges 27 and the side edges 27 are each provided with a wavy edge.

As shown in FIG. 1 to FIG. 6, the combination of the present fan structure 10 is formed by extending a plurality of blades 2 from the outer periphery of the hub 1, and each blade 2 has a shape of a bird wing. Thereby, the air flow passages 24, 24' are formed between the plurality of wing-like projections 23, 23', and the bottom edge 26 and the side edge 27 are respectively wavy edges, so that the airflow generated by the fan structure 10 is affected by the air flow passage 24, 24' and wavy edge guiding, so that the wing-shaped blade 2 has the effect of suppressing the vortex stripping at the center portion, thereby eliminating the backflow originally prevented from peeling, so that the fan structure 10 has an increased static pressure. And the advantages of air volume.

In summary, the fan structure of this creation can achieve the intended purpose of use, and solve the lack of conventional knowledge, and has industrial utilization, novelty and progress, fully comply with the requirements of new patent applications, and apply for patent law. Please carefully check and grant the patent in this case to protect the rights of the creator.
