The outer circumferential side of T-Ring 13 is connected with the inner circumferential side of outer shroud 11, and the inner circumferential side of outer connection ring 13 is connected with the outer circumferential side of inner ring 12.
Baffle liner 10 arranges outer shroud 11 and inner ring 12, make to be perpendicular to baffle liner 10 axial become a mandarin can be through light slip circle
After shape guide face transition, enter the fan blade acting district inside inner ring 12 smoothly, thus reach to avoid eddy current, reduce aerodynamic noise
Purpose.
Concrete, the radius of the outer shroud 11 in the embodiment of the present invention is Ra, and the radius of inner ring 12 is Rb, wherein, and Rb ＜ Ra
＜ 2Rb.It should be noted that the radius value of outer shroud 11 in baffle liner 10 in the embodiment of the present invention and inner ring 12 is at above-mentioned model
When enclosing interior, the minimum effect of noise can be reached.
Preferably, as it is shown on figure 3, outer connection ring 13 is vertical with the axis of rotation of baffle liner 10.
As it is shown on figure 3, outer shroud 11 in the present invention embodiment and/or outer connection are provided with bloop 15 on ring 13.On
It is multiple for stating bloop 15, along outer shroud 11 and the outer bearing of trend connecting ring 13 uniformly at intervals, and the diameter of each bloop 15
For 1mm to 3mm.
Bloop 15 circular in whole baffle liner 10 Surface Machining, air-flow in impact or when flowing through baffle liner 10, office
The tubulence energy of portion's air-flow can be delivered to internal noise reduction region along bloop 15, and is converted into static energy in transmittance process, from
And reduce the purpose of noise.Simultaneously as conference is crossed in the aperture of bloop 15 causes pneumatic spine sound, aperture is too small then can
Lose through hole noise reduction, therefore the diameter of bloop 15 is arranged to the noise reduction effect that 1mm to 3mm can reach optimum
Really.Certainly, the shape of bloop 15 also can be chosen according to different operating situation and need of work, in the embodiment of the present invention
Bloop 15 generally circular in shape, the shapes such as square, rectangle, polygon and ellipse can also be chosen.
As it is shown on figure 3, outer shroud the 11st, outer connection ring the 13rd, the inner ring 12 in the embodiment of the present invention is sequentially connected with and forms inside
Cavity 16, this internal cavities is above-mentioned noise reduction region.Bloop 15 connects with internal cavities 16.Above-mentioned internal cavities is above-mentioned disappearing
Sound region, for improve erasure effect, in the embodiment of the present invention internal cavities 16 cavity wall on be provided with for reducing disappearing of noise
Sound is cotton.
Present invention also offers the second embodiment, as shown in Figure 5 and Figure 6, in this embodiment, baffle liner includes interior company
T-Ring 14, outer connection ring 13 is parallel with vertical direction, and the outer circumferential side of above-mentioned interior connection ring 14 is connected with the outer circumferential side of outer shroud 11, on
The inner circumferential side stating interior connection ring 14 is connected with the inner circumferential side of inner ring 12, and interior connection ring 14 is for towards outer connection ring 13 direction inclination
Taper surface, and interior connection ring 14 is relative to the axis of rotation inclination of baffle liner.
In this embodiment, outer shroud the 11st, outer connection ring the 13rd, inner ring 12 and interior connection ring 14 are sequentially connected with and form sealing
Internal cavities 16, is provided with bloop 15 on outer shroud 11 and outer connection ring 13, and bloop 15 connects with internal cavities 16.
