Description
Technical field
The utility model relates to a kind of fan, particularly relates to the axial fan that a kind of air quantity is large.
Background technique
To be in the cooling fan that to carry in electrical article, OA, IT equipment for cooling heat-generating electronic part.In recent years, commercially, these family's electrical articles, the miniaturization of OA, IT equipment, high performance advance.
Increase for the heating value from electronic unit, as fan, usually adopt small-sized and be easy to obtain the small axial flow fan of air quantity.But current small axial flow fan still is apparent not enough by air quantity that volume is limit.
Model utility content
The utility model, for solving prior art problem, provides the axial fan that a kind of air quantity is large.
The technical solution of the utility model is: a kind of Wind Volume axial fan, comprise framework, the axle center place of described framework is provided with blower fan, described blower fan is fixedly connected with some fan blades, and the axial centre position that described frame inner surface is positioned at described blower fan has the dashpot of the annular arranged around described fan blade.
As preferably, described dashpot along described fan shaft to antetheca and rear wall all perpendicular to the central shaft of described blower fan.
As preferably, the guide cone of the V-arrangement of described fan blade is pointed at the tip that the outer side wall of described dashpot is provided with an annular.
As preferably, the distance between the outermost point of described fan blade and described dashpot outer side wall is not more than 1/5 of described fan blade length.
As preferably, described fan blade favours described fan shaft to setting; The width of described dashpot to be not more than when described fan blade rotates projection width on said frame.
As preferably, described fan blade is fixedly installed on the outer surface of described blower fan; Described blower fan outer surface has the parallel wind groove of some and described fan blade between adjacent described fan blade.
As preferably, the spacing between adjacent described wind groove is equal.
As preferably, described fan blade air side is provided with flange near the central position of described blower fan.
As preferably, the length of described flange is not more than the half of described fan blade length; The thickness of described flange is not more than 5 times of described fan blade thickness.
As preferably, all flangings in described flange surface are circular arc chamfering.
Operationally, what flange can strengthen fan blade pushes away wind effect to traditional axial fan, under same rotational speed, promote air quantity.And complicated flow-disturbing between fan blade and framework, can be formed, these flow-disturbings can disturb the rotation of fan blade, reduce the rotating speed of fan blade.The utility model is at frame inner surface, along the turning circumference of fan blade, open a dashpot, when fan blade high speed rotating, a stable high velocity air can be formed in dashpot by the air of fan blade rotation disturbance, this air-flow can reduce the air pressure in space between fan blade and framework, when making the operation of conventional axial-flow fan, the air disturbance at this position is inhaled into air-flow, simultaneously this high velocity air due to direction identical with fan blade sense of rotation, therefore between fan blade and framework, lubricating layer is formed, effectively reduce fan blade resistance, make the utility model under identical power consumption, than traditional axial fan, there is higher rotating speed, further lifting air quantity.The setting of wind groove effectively can reduce blower fan heating value operationally, can promote fan blade rotating speed to a certain extent to promote air quantity.
In sum, the utility model has the following advantages:
1, under same rotational speed, air quantity, less electrical energy is consumed, low in energy consumption;
2, structure is simple, and improving cost is low.

Embodiment
With embodiment, the utility model is described in further detail below.
Embodiment one:
A kind of Wind Volume axial fan, comprise framework 1, the axle center place of framework 1 is provided with blower fan, blower fan comprises the stator 3 be fixedly connected with framework 1, be arranged at the rotor 4 on stator 3, and be fixedly installed on rotor 4 fan blade 2 circumferentially, stator 3 is near the wind inlet of framework 1, rotor 4 is near the exhaust outlet of framework 1, and the wind inlet side that stator 3 is positioned at framework 1 is provided with chamfering 6.Fan blade 2 is fixedly installed on the outer surface of rotor 4; Rotor 4 outer surface has some wind grooves 5 parallel with fan blade 2 between adjacent fan blade 2, and the chamfering 6 of stator 3 extends to the ingress of wind groove 5 to rotor 4.Spacing between adjacent wind groove 5 is equal.At fan blade 2 and rotor 4, the external diameter between the termination of framework 1 exhaust outlet successively reduces along axially extending to framework 1 exhaust outlet direction of rotor 4 rotor 4, and the minimum outer diameter of rotor 4 is not less than 1/2 of maximum outside diameter.
The axial centre position that framework 1 internal surface is positioned at blower fan has the dashpot 7 of the annular arranged around fan blade 2, and the distance between the outermost point of fan blade 2 and dashpot 7 outer side wall is not more than 1/5 of fan blade 2 length.Dashpot 7 along fan shaft to antetheca and rear wall all perpendicular to the central shaft of blower fan, fan blade 2 favours fan shaft to setting; The width of dashpot 7 is not more than projection width when fan blade 2 rotates on framework 1.The outer side wall of dashpot 7 is provided with the guide cone 8 of the V-arrangement of the tip sensing fan blade 2 of an annular.
Fan blade 2 air side is provided with flange 9 near the central position of blower fan.The length of flange 9 is not more than the half of fan blade 2 length; The thickness of flange 9 is not more than 5 times of fan blade 2 thickness.The surperficial all flangings of flange 9 are circular arc chamfering.
The utility model operationally, in the process of exhausting, most of air is pushed to exhaust outlet from framework 1 hollow part through fan blade 2, has fraction air to be blocked in fan front by stator 3 and forms flow-disturbing, have fraction air by after chamfering 6 along rotor 4 outer surface, by wind groove 5 water conservancy diversion.Fan blade 2 is when high speed rotating, a stable high velocity air can be formed in dashpot 7 by the air of fan blade 2 rotation disturbance, this air-flow can reduce the air pressure in space between fan blade 2 and framework 1, when making the operation of conventional axial-flow fan, the air disturbance at this position is inhaled into air-flow, this high velocity air is identical with fan blade 2 sense of rotation due to direction simultaneously, therefore between fan blade 2 and framework 1, forms lubricating layer.Guide cone 8, for splitting high velocity air, makes high velocity air form a centre fast, the circulation that two ends are slow, strengthens further removing flow-disturbing effect, promotes lubrication effect.What flange 9 can strengthen fan blade 2 pushes away wind effect, under same rotational speed, promote air quantity.
