Description
Technical field
The present invention relates to axial flow blower, more particularly to a kind of axial flow fan vane wheel.
Background technology
Axial flow blower is generally used for factory, warehouse, office, house etc. needs the place of ventilation, certainly, can also answer
For air-cooler（Aerial cooler）, evaporator or condenser etc..
Existing axial flow blower mainly includes casing, the motor loaded on machine box-shrouded impeller and for driving impeller to rotate,
When the impeller is rotated, from air inlet axially into impeller, energy is raised gas under the pushing of the blade on by impeller, is accelerated
And it is deflected to axial flowing.
As can be seen here, the gas flow and flow velocity of axial flow blower generation also mainly receive leaf in addition to being influenceed by impeller
The influence of the shape and construction of piece., integrally in smooth streamline shape, it is to flowing gas for the blade of existing axial flow blower
Push and deflection effect is still weaker.
The content of the invention
The main object of the present invention is to propose a kind of axial flow fan vane wheel, it is intended to improve the pushing and deflection to flowing gas
Effect.
To achieve the above object, the present invention proposes a kind of axial flow fan vane wheel, including wheel hub, and multi-disc is on wheel hub
Blade, the leaf tail of blade is provided with the first kink extended towards the direction bending away from blade negative pressure face.
Technical solution of the present invention the leaf tail of blade be provided with extend towards the direction bending away from blade negative pressure face the
One kink, when gas enters negative pressure face side from blade normal pressure face side, and when partly being spread to the leaf tail of blade,
Under the pushing and guide functions of the first kink, the degree that reduction is radially outward spread, to be more concentrated to away from blade negative pressure
The direction flowing in power face, so that more gas deflections are axially to flow, and then improves the pushing and deflection to flowing gas
Effect, and improve the power of axial flow blower.

The quantity of the technical characteristic for showing.Thus, " first " is defined, the feature of " second " can express or implicitly include at least one
Individual this feature.In addition, the technical scheme between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, when the combination appearance of technical scheme is conflicting or cannot realize it will be understood that this technical side
The combination of case does not exist, not within the protection domain of application claims yet.
The present invention proposes a kind of axial flow fan vane wheel.
In the embodiment of the present invention, as shown in Figures 1 to 3, the axial flow fan vane wheel includes wheel hub 1, and multi-disc is located at wheel hub 1
On blade 2, the quantity of blade 2 can set according to the actual requirements, for example can for two panels, three, four, five or more
It is many, it is as shown in Figure 1 the situation of three, more blades 2 are uniformly distributed around the axis of wheel hub 1, to ensure the stabilization of impeller operation
Property.The leaf tail of blade 2 is provided with the first kink 21 extended towards the direction bending away from the negative pressure face of blade 2, when gas from leaf
Piece normal pressure face side enters negative pressure face side, and when partly being spread to the leaf tail of blade 2, in the pushing of the first kink 21
Under guide functions, the degree that reduction is radially outward spread, to be more concentrated at being flowed to the direction away from blade negative pressure face, from
And make more gas deflections axially to flow, and then the pushing to flowing gas and deflection effect are improved, and improve axle stream wind
The power of machine.It should be noted that the side that blade 2 is connected with wheel hub 1 is defined as blade root here, by blade 2 away from wheel hub 1
Side be defined as leaf tail.
Further, as shown in Figure 1 and Figure 2, the curved bending of first kink 21, the set-up mode of arc bending
Preferably gas can be oriented to, the width of the first kink 21 gradually increases from leading edge to trailing edge, can strengthen to gas
Push and deflection effect.
Further, as shown in Figure 1 and Figure 2, the adjacent area of the blade root of blade 2 and trailing edge（Both corner regions in other words
Domain）The second kink 22 extended towards the direction bending away from the negative pressure face of blade 2 is provided with, when gas from the normal pressure face of blade 2
Side enters negative pressure face side, and when partly being spread to the trailing edge of blade, pushing and water conservancy diversion of the gas in the second kink 22
Under effect, the degree for radially outward spreading further is reduced, more intensively to be flowed to the direction away from the negative pressure face of blade 2
It is dynamic, so that more gas deflections are axially to flow, and then further improve pushing and deflection effect to flowing gas, and
Further improve the power of axial flow blower, it should be noted that be here respectively connected with the two ends at the two ends of blade root and leaf tail
Both sides are defined as the leading edge and trailing edge of blade 2, when blade 2 turns clockwise（The signified direction such as arrow in Fig. 1）, leading edge
It is always located in the front of trailing edge.
Further, the curved bending of second kink 22, the set-up mode of arc bending can preferably to gas
Water conservancy diversion is carried out, the width of the second kink 22 is gradually reduced from blade root to leaf tail, can strengthen the pushing to gas and deflection effect.
Specifically, the wheel hub 1 includes cylindrical wheel portion 11 and the perisporium located at the wheel portion 11 and to extension
The connecting portion 12 stretched, wheel portion 11 directs or through the outer rotor of motor of the middleware loaded on axial flow blower（It is not shown）On, and
Can be in motor（It is not shown）Driving under rotate, the connecting portion 12 can by welding located at wheel portion 11 perisporium or with wheel
Portion 11 is integrally formed.The root of the blade 2 is connected with connecting portion 12.Specifically, the root of the blade 2 leads to connecting portion 12
Bolt is crossed to be detachably connected or by rivet, or, when blade 2 and connecting portion 12 are metal to be made, the He of blade 2
Connecting portion 12 can be connected by welding manner, or can be had using integrally formed structure, integrally formed structure
Convenient formation, the advantage of low cost.It should be noted that at this moment signified direction " outward " can be regarded as radially away from the axle of wheel hub 1
The direction of line, then may be defined as " interior " towards the direction at the center of wheel hub 1.
Further, the normal pressure face of blade 2 forms reinforcement 23, to improve the structural strength of blade 2.Specifically,
The quantity of reinforcement 23 can as shown be the situation of three for one or more of, its along blade 2 normal pressure face diameter to
It is spaced apart.
The preferred embodiments of the present invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every at this
Under the inventive concept of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/use indirectly
It is included in scope of patent protection of the invention in other related technical fields.
