Connect.
Setting outer shroud 11 and internal ring 12 on baffle liner 10, making can be through light slip circle perpendicular to becoming a mandarin of baffle liner 10 axial direction
After shape guide face transition, smoothly entering the fan blade acting area of internal ring 12 inner side, thus reach to avoid being vortexed, reducing aerodynamic noise
Purpose.
Specifically, the radius of the outer shroud 11 in this utility model embodiment is Ra, and the radius of internal ring 12 is Rb, wherein, Rb
＜ Ra ＜ 2Rb.It should be noted that the radius value of outer shroud 11 in baffle liner 10 in this utility model embodiment and internal ring 12
When within the above range, the minimum effect of noise can be reached.
Preferably, as shown in figure 3, outer connection ring 13 is vertical with the axis of rotation of baffle liner 10.
As shown in figure 3, being provided with bloop in outer shroud 11 in this utility model embodiment and/or outer connection ring 13
15.Above-mentioned bloop 15 be multiple, along outer shroud 11 and outer connection ring 13 bearing of trend uniformly at intervals, each bloop 15
A diameter of 1mm to 3mm.
The circular bloop 15 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
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 job demand, and this utility model is implemented
Example in bloop 15 generally circular in shape, the shapes such as square, rectangle, polygon and ellipse can also be chosen.
As shown in figure 3, outer shroud 11 in this utility model embodiment, outer connection ring 13, internal ring 12 are sequentially connected and are formed
Internal cavities 16, this internal cavities is above-mentioned noise reduction region.Bloop 15 is connected with internal cavities 16.Above-mentioned internal cavities are upper
State noise reduction region, for improving erasure effect, be provided with for reducing in the cavity wall of internal cavities 16 in this utility model embodiment
The silencing cotton of noise.
This utility model additionally provides second embodiment, and as shown in Figure 5 and Figure 6, in this embodiment, baffle liner includes
