Specific embodiment
The invention discloses a kind of through-flow fan blades, reduce through-flow fan blade vibration, improve Energy Efficiency Ratio.The present invention also provides one
Kind has the blower of above-mentioned through-flow fan blade.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figures 1 and 2, the present invention provides a kind of through-flow fan blades, including fan blade ontology 1 and anti-channelling partition 2.It is anti-
Channelling partition 2 is set in the hollow structure inside of fan blade ontology 1, also, anti-channelling partition 2 divides inner hollow for axial
Structure.
Through-flow fan blade provided in an embodiment of the present invention, by the way that anti-channelling is arranged in the hollow structure inside of fan blade ontology 1
Partition 2 has haved the function that axial segmentation hollow structure inside.Even if the pressure unevenness of the axial position in through-flow fan blade
In the case of, air-flow generates axial movement and flows along hollow structure inside, after air-flow encounters anti-channelling partition 2, can also interrupt
The channelling of air-flow, and be forced to throw away from the corresponding position of fan blade ontology 1, and then the case where avoid air-flow axial float, guarantee
The air output of fan blade ontology 1 same axial position is almost the same with intake, effectively reduces the vibration of through-flow fan blade, improves
Energy Efficiency Ratio.
Further, axis of the anti-channelling partition 2 perpendicular to fan blade ontology 1.By above-mentioned setting, avoid anti-channelling every
Obstruction of the plate 2 to through-flow fan blade outlet air and air inlet, it is ensured that air-supply effect.
In the present embodiment, the quantity of anti-channelling partition 2 is multiple.By the way that multiple anti-channelling partitions 2 are arranged, further keep away
The case where having exempted from air-flow axial float.

And increase the effect of air quantity.After external air flow enters venturi runner 3 by the first section a of venturi runner 3, free air space away from
From being gradually reduced, according to fluid continuity equation, reduce along journey section, flow velocity necessarily increases；At second section of venturi runner 3
Flow velocity reaches maximum at the b of face, and then flow area gradually increases, and flow velocity decreases, and by the third section of venturi runner 3
C outflow.Air-flow can generate certain negative pressure near the first section a during flowing through the second section b by the first section a,
Peripheral gas flow participates in the flowing of air-flow by pressure differential and enters the first section a, to achieve the purpose that increase flow.Experiment
It proves, by making two neighboring anti-channelling partition 2 form venturi runner 3, rate of discharge increases 20~25%.
In the present embodiment, the end face of anti-channelling partition 2 has convex globoidal region.By by the end face of anti-channelling partition 2
With convex globoidal region, in order to form venturi runner 3 between two neighboring anti-channelling partition 2, also, air-flow is along convex arc
Face movement, free air space are gradually reduced apart from continuity, thereby reduce air-flow flowing energy consumption.It can also make anti-channeling stream partition 2
End face have tapered surface region.
Further, the center line in convex globoidal region is overlapped with the axis of fan blade ontology 1.By above-mentioned setting, so that literary
Runner 3 forms symmetrical structure in mound, in order to 3 pairs of venturi runner air inlets and the stabilization of outlet air.As shown in figure 3, passing through
Above-mentioned setting, the first section a are identical as third section c's.By above-mentioned setting, so that convex globoidal region is located at anti-channelling partition
2 middle section.
Further, the end face of anti-channelling partition 2 also has the plane domain at the edge positioned at convex globoidal region, plane
Region extends to the edge of anti-channelling partition 2.That is, the both ends of venturi runner 3 are the plane by two neighboring anti-channelling partition 2
The direct current section that region is formed, in order to flow out the air-flow for flowing out venturi runner 3 linearly under direct current section guidance.
As shown in Fig. 4 and Fig. 6, in the present embodiment, Ra < Rb-1.1L；Wherein, Ra is the radius in convex globoidal region；Rb
For the radius of fan blade ontology 1；L is the chord length of 1 blade of fan blade ontology.By above-mentioned setting, so that plane domain is along anti-channelling
Radial thickness H >=Rb-Ra-L of partition 2, in order to the connection of anti-channelling partition 2 and the entity part of fan blade ontology 1.That is, H
> 0.1L, it is ensured that the diversion effect of above-mentioned direct current section.
As shown in figure 5, convex globoidal region extends to the edge of anti-channelling partition 2 in second of embodiment.It facilitates anti-
The processing of channelling partition 2.
It can also prolong in the edge setting corrugated surface or cambered surface region, corrugated surface or cambered surface region for being located at convex globoidal region
Extend to the edge of anti-channelling partition 2.
As shown in Figure 1, fan blade ontology 1 is made of multiple median segment of cross-flow fan blade.Wherein, median segment of cross-flow fan blade is along fan blade ontology
1 axial alignment.
For the ease of the setting of anti-channelling partition 2, anti-channelling partition 2 is located at the connection of two neighboring median segment of cross-flow fan blade
Place.
