Abstract
The utility model discloses a be applied to fan of making an uproar that falls of server belongs to bionics and aerodynamic field. The structure of the fan comprises a rotating shaft, wherein at least two blades are arranged on the rotating shaft; a plurality of cylindrical arc-shaped bulges are transversely arranged on the fan blade, and a plurality of triangular gaps are symmetrically arranged on two sides of the fan blade; wherein, the bulges and the notches are distributed at intervals. The utility model has the advantages that: through combining bionics to the wing of the better long ear owl of aerodynamics in nature is as reference model, imitates the feather level and the feather edge of long ear owl, sets up arch and breach on the flabellum respectively, makes the flabellum more accord with aerodynamics, and the design is exquisite, and is practical convenient simple, has not only reduced the noise of server, has still improved the result of use of equipment, has very strong use value and wide application prospect.
Description
Technical field
This utility model relates to bionics and aerodynamic scope, particularly to a kind of noise-reduction fan being applied to server.
Background technology
Along with the development of informationized society, the application of server is more and more extensive.Owing to the cpu frequency of server is high, workload is big, need to be produced by boasting by the heat that it is internal with fan, to ensure the normal work of server.But, the fan noise of current server is relatively big, is mostly about 70db.It is chronically in such noise, health is had certain harm.
Summary of the invention
In order to solve problem of the prior art, this utility model embodiment provides a kind of noise-reduction fan being applied to server.
Described technical scheme is as follows:
A kind of noise-reduction fan being applied to server, including rotating shaft, described rotating shaft is provided with at least two valve leaves；Being horizontally arranged with multiple projection in cylinder camber on described flabellum, described flabellum lateral symmetry is provided with multiple breach triangular in shape；Wherein, described protruding and described breach distributes alternately.
Further, described flabellum is preferably page four, is arranged at equal intervals in rotating shaft.
Further, described protruding and described breach is the most equidistantly distributed.
Further, the width a of described projection is 1mm.
Further, described projection is 5mm to distance b between adjacent described breach.
Further, distance c between two described breach closed on is 10mm.
The technical scheme that this utility model embodiment provides has the benefit that
By combining bionics, with the brave wing of the preferable screech owl of aerodynamic in nature as reference model, imitate the brave feather level of screech owl and feather edges, projection and breach are set respectively on flabellum, make flabellum more meet aerodynamic.This utility model deft design, practical and convenient simply not only reduce the noise of server, also improve the using effect of equipment, there is the strongest use value and wide application prospect.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of flabellum of the present utility model.
Wherein, 1, rotating shaft, 2, flabellum, 21, protruding, 22, breach, a, 1mm, b, 5mm, c, 10mm.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
Embodiment one
As shown in drawings, a kind of noise-reduction fan being applied to server of the present utility model, including rotating shaft 1, described rotating shaft 1 is provided with at least two valve leaves 2；Being horizontally arranged with multiple projection 21 in cylinder camber on described flabellum 2, described flabellum 2 lateral symmetry is provided with multiple breach 22 triangular in shape；Wherein, described protruding 21 and described breach 22 distribute alternately.
Preferably, described flabellum 2 is preferably page four, is arranged at equal intervals in rotating shaft 1.
Preferably, described protruding 21 and described breach 22 be the most equidistantly distributed.
Preferably, the width a of described protruding 21 is 1mm.
Preferably, described protruding 21 is 5mm to distance b between adjacent described breach 22.
Preferably, distance c between two described breach 22 closed on is 10mm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
