Abstract
The utility model is about a kind of fan structure with discontinuity surface, this fan structure includes a wheel hub and plural flabellum, and from the outer peripheral edge of wheel hub, integrated elongation moulding, the top surface of each flabellum have discontinuous plural curved surface each other to plural flabellum outward.Whereby, discontinuous plural curved surface can generate the flow velocity of different location each other, and then reduce the narrow frequency noise generated when fan structure operating.
Description
Technical field
The utility model relates to a kind of fan structure, and in particular to a kind of fan knot with discontinuity surface
Structure.
Background technique
The components such as the electronic building brick inside electronic device, such as mainboard, central processing unit and integrated circuit, when operating all
Can generate high fever, electronic building brick accumulation heat and when can not radiate, electronic building brick will be damaged or the problems such as short circuit.Cause
This, to radiators such as electronic building brick setting radiator fans, is to ensure that maintain efficiency and stability when electronic building brick running
One of the method for electronic building brick energy normal operation.
However, traditional heat-dissipating fan mainly includes a fan frame and the fan body being mounted in fan frame, this fan body
With a wheel hub and it is arranged on wheel hub and encloses each other the plural flabellum for being set as a circle, but the surface of each flabellum constitutes one continuously
Face causes flow position to concentrate, and higher narrow frequency noise can be generated when fan body being caused to operate.Therefore how to reduce fan
The narrow frequency noise that ontology generates when operating is that radiator fan manufacturer wants the emphasis pursued.
Utility model content
The technical problems to be solved in the utility model is provided a kind of with discontinuous according to above-mentioned the deficiencies in the prior art
The fan structure in face, and then realize the narrow frequency noise generated when reduction fan structure operating.
The technical solution of the utility model is as follows:
A kind of fan structure with discontinuity surface, comprising:
One wheel hub (1)；And
Plural flabellum (2), from the outer peripheral edge of the wheel hub (11) integrated elongation moulding outward, the top surface of each flabellum (2)
(21) there is discontinuous plural curved surface (22) each other.
Further, a difference of height (h) is formed between two adjacent curved surfaces (22).
Further, the height of the plural curved surface (22) of each flabellum (2) is gradually passed towards far from wheel hub (1) direction
Subtract.
Further, the top surface (21) of each flabellum (2) is a stepped surfaces (3).
Further, the height of the plural curved surface (22) of each flabellum (2) is with the arrangement of interval concavo-convex manner.
Further, the top surface (21) of each flabellum (2) is a serrated surface (4).
Further, plural flabellum (2) arrangement equally spaced from each other.
Further, Unequal distance arranges the plural flabellum (2) each other.
Compared with prior art, the utility model has the following beneficial effects: the top surface using each flabellum has each other
Discontinuous plural number curved surface, discontinuous plural curved surface can generate the flow velocity of different location each other, and then reduce fan structure fortune
The narrow frequency noise generated when turning.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
It please refers to shown in Fig. 1 to Fig. 5, the utility model is to provide a kind of fan structure with discontinuity surface, this fan
Structure 10 mainly includes a wheel hub 1 and plural flabellum 2.
As shown in Figures 1 to 5, plural flabellum 2 is from the outer peripheral edge of wheel hub 11 integrated elongation moulding outward, each flabellum 2
Top surface 21 has discontinuous plural curved surface 22 each other, i.e., two curved surfaces 22 adjacent to each other can not constitute a continuous surface, adjacent
A difference of height h is formed between two curved surfaces 22.Wherein, plural flabellum 2 can it is equally spaced from each other arrangement or each other Unequal distance arrange, not with
The present embodiment is limitation.
Detailed description are as follows, and the height of the plural curved surface 22 of each flabellum 2 is gradually successively decreased towards far from 1 direction of wheel hub, thus
The top surface 21 for enabling each flabellum 2 is one ladder-like, and system that but not limited to this, the height of the plural curved surface 22 of each flabellum 2 can also
Gradually it is incremented by towards far from 1 direction of wheel hub.
The use state of the utility model fan structure 10 is that have not connect each other using the top surface 21 of each flabellum 2
Continuous plural curved surface 22, discontinuous plural curved surface 22 can generate the flow velocity of different location each other, and then reduce fan structure 10
The narrow frequency noise generated when operating.
It please refers to shown in Fig. 6, is another embodiment of the utility model fan structure 10, the embodiment and Fig. 1 of Fig. 6 is extremely schemed
5 embodiment is roughly the same, the embodiment of Fig. 6 height that is in plural curved surface 22 different from the embodiment of Fig. 1 to Fig. 5 with
It is spaced concavo-convex manner arrangement, i.e., the low curved surface 22 of a height is equipped between the high curved surface 22 of every two height, to enable each
The top surface 21 of flabellum 2 is a zigzag, however, the top surface 21 of flabellum 2 is ladder-like or zigzag, it is discontinuous each other on flabellum 2
Plural curved surface 22 can all generate the flow velocity of different location, to reach the function and effect of the embodiment for being identical to Fig. 1 to Fig. 5.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
