Abstract
The utility model discloses a kind of banded fans, comprise flabellum, described flabellum comprises impeller (10) and around the multiple blades (20) be arranged on described impeller (10), described blade (20) is S-type in the radial direction of described impeller (10), and be curved surface, the front of described blade (20) is provided with the curve striped (21) protruding or cave in.The aforementioned banded fans that the utility model provides, the curved surface bucket of its S type and the design of blade upper curve striped, enhance draft capacity, the high and beautiful shape of radiating efficiency.
Description
Technical field
The utility model relates to a kind of S type banded fans.
Background technique
Along with the development of electronic technology, various electronic equipment continues to bring out, and the higher electronic device extensive use of the heating value such as power supply and microprocessor in the electronic device.In addition, along with the miniaturization of electronic equipment, the high-density installation of electronic circuit is prevailing, and thus the heat generation density of electronic equipment is also increasing gradually, and thus the heat dissipation problem of electronic equipment has become that electronic equipment research and development are important considers problem.
Existing fan appearance design is more common, and air output is general, and radiating efficiency is not high.Leaf structure is also more stiff, has nothing in one, and on blade, the setting of striped is also only the straight line without any radian, and all sets on flat leaf, do not have independent leaf for S type curved surface on arrange.
Model utility content
Main purpose of the present utility model be propose a kind of novel banded fans, with increase attractive in appearance while reduce windage, improve radiating efficiency.Concrete scheme is as follows:
A kind of banded fans, comprise flabellum, described flabellum comprises impeller and around the multiple blades be arranged on described impeller, described blade is S-type in the radial direction of described impeller, and is curved surface, and the front of described blade is provided with the curve striped protruding or cave in.In the technical program, the design of face of blade upper curve striped, adds the draft capacity of blade, improves air quantity.
Preferably, described curve striped is uniformly distributed in described blade one end away from described impeller, and curved shape.
Preferably, each described blade at least has a described curve striped.
Preferably, each described blade at least have three described curve stripeds.
Preferably, the root that described blade is combined with described impeller has the double wedge withheld on described impeller, and the root that described double wedge is combined with described impeller is the wedge angle protruded, and described double wedge is uniformly distributed on described impeller.The double wedge of root of blade can concentrating portions air quantity, keeps watch again and diffuses on blade, thus greatly enhance the air intake efficiency of flabellum after vane rotary.
Preferably, the center, the back side of described impeller is provided with the axle core connecting groove for connecting fan shaft core, the outer internal projecting ring be arranged with for installing motor of described axle core connecting groove.
Preferably, the outer outer bulge loop be arranged with for the protection of described internal projecting ring of described internal projecting ring.Outer bulge loop can protect internal projecting ring not by outside destroy, thus protects the safety and stability running of motor well.
In a word, the aforementioned banded fans that the utility model provides, the curved surface bucket of its S type and the design of blade upper curve striped, enhance draft capacity, the high and beautiful shape of radiating efficiency.
Accompanying drawing explanation
Fig. 1 is the flabellum front schematic view of the banded fans that the utility model embodiment provides;
Fig. 2 is the schematic perspective view of the flabellum of Fig. 1;
Fig. 3 is the schematic rear view of the flabellum of Fig. 2.
Embodiment
Below contrast accompanying drawing and combine preferred embodiment the utility model is described in further detail.
Embodiment of the present utility model provides a kind of banded fans, comprise flabellum as shown in Figures 1 to 3, described flabellum comprises impeller 10 and around the multiple blades 20 be arranged on described impeller 10, described blade 20 is S-type in the radial direction of described impeller 10, and blade 20 entirety is curved design, the front of described blade 20 is provided with the curve striped 21 protruding or cave in.As a kind of preferred embodiment, impeller 10 is provided with equably 9 blades 20, each blade 20 is evenly distributed with the curve striped 21 of 3 projections, and curve striped 21 is arranged near blade 20 end (for root, root is the position that blade is connected to impeller).Need to illustrate, curve striped 21 also can be depressed in face of blade, and arranging of quantity can carry out appropriate design according to the size of the length of curve striped, thickness and blade, such as, also can be designed as 1,2,4,5,6 etc.Curve striped 21 is curved shape preferably.
In some preferred embodiments, as shown in Figure 2, the root of blade 20 has the double wedge 22 protruding from impeller 10, double wedge 22 withholds the front in impeller 10, further, the root that double wedge 22 is combined with impeller 10 is the wedge angle protruded, and the design of double wedge can concentrating portions air quantity, keep watch again after vane rotary and diffuse on blade, thus greatly enhance the air intake efficiency of flabellum.Preferably, double wedge 22 is distributed in equably on impeller 10.
In another kind of preferred embodiment, the front of impeller 10 is convex closure shape, and the circle bag namely heaved, this design effectively can reduce windage when flabellum operates, and improves air intake efficiency, can also arrange LOGO above.
As shown in Figure 3, the center, the back side of impeller 10 is provided with the axle core connecting groove 11 for connecting fan shaft core, the outer internal projecting ring 12 be arranged with for installing motor of axle core connecting groove 11, in order to prevent outside destroy for loading the internal projecting ring 12 of fan motor, in more excellent mode, be also arranged with evagination ring 13 at the outer of internal projecting ring 12.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; some equivalent to substitute or obvious modification can also be made, and performance or purposes identical, all should be considered as belonging to protection domain of the present utility model.
