Description

Fan structure with discontinuous surface

The present invention relates to a fan structure, and in particular to a fan structure having a discontinuous surface.

The electronic components inside the electronic device, such as the motherboard, the central processing unit, and the integrated circuit, all generate high heat during operation. When the electronic components accumulate heat and cannot dissipate heat, the electronic components may be damaged or short-circuited. Therefore, in order to maintain the efficiency and stability of the operation of the electronic component, it is one of the methods for ensuring that the electronic component can operate normally by providing a heat sink such as a cooling fan for the electronic component.

However, the conventional cooling fan mainly includes a frame and a fan body mounted in the fan frame. The fan body has a hub and a plurality of blades disposed on the hub and surrounded by a circle, but each of the blades The surface forms a continuous surface, causing the flow velocity to be concentrated, resulting in high narrow-band noise when the fan body is running. Therefore, how to reduce the narrow-frequency noise generated when the fan body is running is the focus of the heat-dissipating fan manufacturers.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The present invention provides a fan structure having a discontinuous surface, which uses a top surface of each blade to have a plurality of curved surfaces that are discontinuous with each other, and a plurality of mutually discontinuous curved surfaces generate flow velocity at different positions, thereby reducing the operation of the fan structure. Narrowband noise.

In the present embodiment, the present invention provides a fan structure having a discontinuous surface, comprising: a hub; and a plurality of blades extending integrally from the outer periphery of the hub, the top surface of each of the blades There are complex surfaces that are not continuous with each other.

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. 5 , the present invention provides a fan structure having a discontinuous surface. The fan structure 10 mainly includes a hub 1 and a plurality of blades 2 .

As shown in FIG. 1 to FIG. 5, the plurality of blades 2 are integrally formed outwardly from the outer periphery of the hub 11, and the top surface of each of the blades 2 has a plurality of curved surfaces 22 that are discontinuous with each other, and between the adjacent two curved surfaces 22 A height difference h is formed, that is, the two curved surfaces 22 adjacent to each other cannot constitute a continuous surface. The plurality of blades 2 may be arranged equidistantly from each other or not equidistant from each other, and are not limited by the embodiment.

As described in detail below, the height of the plurality of curved surfaces 22 of each of the blades 2 is gradually decreased toward the direction away from the hub 1, so that the top surface of each of the blades 2 is a stepped surface 3, but not limited thereto. The height of the plurality of curved surfaces 22 of the leaves 2 may also gradually increase in a direction away from the hub 1.

In the state of use of the fan structure 10, the top surface of each blade 2 has a plurality of curved surfaces 22 that are discontinuous with each other, and the plurality of curved surfaces 22 that are discontinuous with each other generate flow velocity at different positions, thereby reducing the operation of the fan structure 10. The resulting narrow-band noise.

Please refer to FIG. 6 , which is another embodiment of the present fan structure 10 . The embodiment of FIG. 6 is substantially the same as the embodiment of FIGS. 1 to 5 . The embodiment of FIG. 6 and the embodiment of FIG. 1 to FIG. 5 . The difference is that the heights of the plurality of curved surfaces 22 are arranged in an uneven manner, that is, a curved surface 22 having a low height is provided between each of the two curved surfaces 22 so that the top surface of each of the blades 2 is a sawtooth surface. 4. However, regardless of whether the top surface of the blade 2 is a stepped surface 3 (as shown in FIG. 5) or the serrated surface 4, the plurality of curved surfaces 22 on the fan blade 2 that are not continuous with each other will generate flow rates at different positions to achieve the same The functions and effects of the embodiments of Figures 1 to 5.

In summary, the fan structure with discontinuous surface of the 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 patent application requirements, and convert If the patent law is filed, please check and grant the patent in this case to protect the rights of the creator.
