Abstract
A kind of fan guard of improvement system wind flow field, protective cover are detachably arranged on fan drum, and protective cover is equipped with blend stop, and protective cover is divided into several wind outlet areas in parallel by each blend stop, and blend stop dissipates the air-out direction of fan outward.Not only play the role of protective cover, but also the wind flow field of system can be improved.Blend stop plays rectified action to flow field on front side of fan, and the wind of big tilt angle can be rectified to the wind for becoming Parallel airflow or small tilt angle, keep air-flow more evenly gentle, reduces the fluctuation of air-flow, and then reduces air-flow to the high-frequency vibration of hard disk.Meanwhile while blend stop proof strength, utmostly reduce windage.High speed it is distinguished and admirable by elliptic cross-section vertical bar when, fluid cross-section product reduces, and flow velocity increases, and entire distinguished and admirable flow is constant.
Description
Technical field
The utility model relates to server accessory technical field, in particular to a kind of fan protection of improvement system wind flow field
Cover.
Background technique
With the fast development of electronic component, high density, high power consumption, the electronic component of high heat are more and more, clothes
Calorific value inside business device is also significantly increased, and high-revolving fan is needed to radiate at this time.Rotation speed of the fan is higher, distinguished and admirable flow velocity
Also faster, the high-frequency vibration that wind flow field generates is bigger, and the distinguished and admirable influence to hard disk is also bigger.
Utility model content
To overcome problems of the prior art, the fan that the utility model provides a kind of improvement system wind flow field is protected
Shield.
The technical solution adopted by the utility model to solve its technical problems is that: the fan that this kind improves system wind flow field is protected
Shield, protective cover are detachably arranged on fan drum, and protective cover is equipped with blend stop, and each blend stop in parallel divides equally protective cover
For several wind outlet areas, blend stop dissipates the air-out direction of fan outward.
Further, the cross section of the blend stop is ellipse, and it is close that two oval narrow ends are located at protective cover
Fan side and separate fan side.
Further, the cross section of the blend stop is half elliptic, and the narrow end of half elliptic is located at protective cover close to fan
Side, wide end are located at protective cover far from fan side.
Further, the cross section of the blend stop be isosceles triangle, and the waist edges intersection point such as isosceles triangle two one end position
In protective cover close to fan side, it is located at protective cover far from fan side, isosceles triangle rounding with one end of the intersection point face
Angle.
Further, four angles of the protective cover are clamped by buckle and fan, and are equipped between protective cover and fan close
Seal rubber buffer.
To sum up, the above-mentioned technical proposal of the utility model has the beneficial effect that:
This protective cover by multiple ellipses or half elliptics or the vertical bar of isoceles triangle tee section be fixed in square box,
It is installed on front side of fan, not only plays the role of protective cover, but also the wind flow field of system can be improved.Ellipse or half elliptic or isosceles
The vertical bar of triangular-section plays rectified action to flow field on front side of fan, and can rectify the wind of big tilt angle becomes Parallel airflow or small
The wind of tilt angle keeps air-flow more evenly gentle, reduces the fluctuation of air-flow, and then reduces air-flow to the high-frequency vibration of hard disk.Together
When, ellipse or half elliptic or isoceles triangle tee section while guarantee the vertical bar intensity, utmostly reduce windage.Root
Theoretical according to hydrodynamics Bernoulli equation, when fluid cross-section product reduces, flow velocity increases, and flow remains unchanged.The distinguished and admirable warp of high speed
When crossing elliptic cross-section vertical bar, fluid cross-section product reduces, and flow velocity increases, and entire distinguished and admirable flow is constant.
Vibration caused by the seal rubber cushion being arranged between protective cover and fan can effectively prevent protective cover from loosening,
Reduce influence of the high-frequency vibration to hard disk.
This is reasonable in design, ellipse half elliptic or isoceles triangle tee section vertical bar protective cover both play fan
Protective cover effect, and the wind flow field of system can be improved, it is provided simultaneously with enough intensity, in system optimization, cost savings, processing peace
Dress aspect has some superiority.

In figure:
1 protective cover, 2 fans, 3 ellipses, 4 half elliptics, 5 isosceles triangles, 6 close to fan side, and 7 far from fan one
Side, 8 blend stops, 9 buckles.
Specific embodiment
It is described in detail below in conjunction with feature and principle of the attached drawing to the utility model, illustrated embodiment is only used for explaining
The utility model not limits the protection scope of the utility model with this.
As shown in Figure 1 and Figure 2, this kind improves the fan guard 1 of system wind flow field, and protective cover 1 is detachably arranged at fan
On 2 shells, protective cover 1 is equipped with blend stop 8, and protective cover 1 is divided into several wind outlet areas in parallel by each blend stop, and blend stop 8 makes
The air-out direction for obtaining fan 2 dissipates outward.
As shown in figure 3, the cross section of blend stop 8 is ellipse 3, it is close that two narrow ends of ellipse 3 are located at protective cover 1
Fan side and separate fan side.
As shown in figure 4, the cross section of blend stop 8 is half elliptic 4, the narrow end of half elliptic 4 is located at protective cover 1 close to fan
Side 6, wide end are located at protective cover 1 far from fan side 7.
As shown in figure 5, the cross section of the blend stop 8 is isosceles triangle 5, and waist edges intersection points one such as 5 liang of isosceles triangle
End is located at protective cover 1 close to fan side 6, is located at protective cover 1 far from fan side 7, isosceles three with one end of the intersection point face
Angular rounded corner.
Four angles of protective cover 1 are clamped by buckle 9 and fan, and 9 insertion ends of buckle are tip, with engaging limiting stand
10. and being equipped with seal rubber cushion between protective cover 1 and fan.Seal rubber cushion between protective cover 1 and fan is set
Vibration caused by can effectively preventing protective cover 1 from loosening reduces influence of the high-frequency vibration to hard disk.
This protective cover 1 by multiple oval 3 half elliptic 4 or 5 section of isosceles triangle vertical bar be fixed on it is rectangular
In frame, it is installed on front side of fan, had not only played the role of protective cover 1, but also the wind flow field of system can be improved.Ellipse or half elliptic or
The vertical bar of isoceles triangle tee section rectified action is risen to flow field on front side of fan, can rectify the wind of big tilt angle becomes parallel
The wind of wind or small tilt angle keeps air-flow more evenly gentle, reduces the fluctuation of air-flow, and then reduces air-flow to the high frequency vibrating of hard disk
It is dynamic.Meanwhile ellipse or half elliptic or isoceles triangle tee section while guarantee the vertical bar intensity, utmostly reduce wind
Resistance.Theoretical according to hydrodynamics Bernoulli equation, when fluid cross-section product reduces, flow velocity increases, and flow remains unchanged.The wind of high speed
When stream is by elliptic cross-section vertical bar, fluid cross-section product reduces, and flow velocity increases, and entire distinguished and admirable flow is constant.
This is reasonable in design, ellipse half elliptic or isoceles triangle tee section vertical bar protective cover 1 both play wind
It fans protective cover 1 to act on, and the wind flow field of system can be improved, be provided simultaneously with enough intensity, in system optimization, cost savings, add
Work installation has some superiority.
