The present invention proposes a kind of air fairing, and referring to FIG. 1, FIG. 2 and FIG. 4, which includes rectification gear
Block 1 and air-duct spiral case 2, the tubular wine wheel 10 of air conditioner is equipped in air-duct spiral case 2, which includes constituting air conditioner
The lower frame 21 and upper side frame 22 in air duct, air-duct spiral case 2 guide the air-flow that the tubular wine wheel 10 of air conditioner introduces to air outlet W
Outflow determines air conditioner in the lower frame 21 towards low on 22 side of upper side frame based on the angle of lower frame 21 and upper side frame 22
Fast area S, rectification block 1 are set in the S of the low regime.
Air-duct spiral case 2 is mounted therein by tubular wine wheel 10, and the inner wall of air-duct spiral case 2 is to tubular wine wheel 10 from external pumping
The air-flow entered is drained (as shown in Fig. 2 air current flow directions F), and most of air-flow, which circulates to air-conditioned wind tunnel air outlet W, to flow
Go out, fraction air-flow is again introduced into the airflow circulating in air-duct spiral case 2 from the vortex tongue around 22 end of upper side frame.Rectification block 1
Being arranged on lower frame 21 in the low regime S at air outlet, i.e., rectification block 1 is arranged on the air-out direction of air conditioner,
The cross section of the rectification block 1 can be arbitrary shape, such as outer convex, concave arc, polygon etc..With reference to Fig. 5, the rectification
Block 1 can be one, and the rectification block 1 is to extend set on 21 surface of lower frame and along the length direction of the lower frame 21
Whole continuous strip block；Rectification block 1 can be multiple, and the rectification block 1 is set to lower frame 21 along length
The both ends in direction.
Low regime S is related to angle formed by the lower frame 21 of air-duct spiral case 1 and upper side frame 22, the more big then low speed of the angle
The range in area is bigger.Specifically, can be by probe velocimetry on lower frame 21, especially the two of 21 length direction of lower frame
End, air-out direction on detection obtain low regime S (gas flow rate is known as low speed less than preset value), rectification block 1 is set to this
In the S of low regime.Optionally, referring to Figures 1 and 2, low regime S is by the positive and negative 15 degree of areas radiated of eccentric vertical line on lower frame 21
Domain, the bias vertical line are hung down using the center O of the eccentric vortex of air-conditioned wind tunnel as basic point, to made by 21 place plane of lower frame
Line；The coverage area of rectification block 1 is slightly larger than the coverage area of low regime S, to rectification block 1 to the air-flow of low regime S into
Row speed-raising comprehensively will not flow back after being further ensured that all air-flows outflow air outlet W for flowing through low regime S.
In the present embodiment, it is arranged in the low regime at air outlet W by the lower frame 21 in air fairing
Rectification block 1, rectification block 1 are arranged on the air-out direction of air conditioner, to rectification block 1 by air outlet W outlet air section into
Row blocks, and reduces the outlet air area of section of air outlet W, and the local lifting flow velocity of eluting gas uses pneumatic pressure increasing, from

The stability of air-flow is blown out in air conditioner, air turbulence is avoided and generates abnormal sound.
Further, rectification block 1 towards the one side inside air-duct spiral case 2 be inclined-plane, due to inclined-plane to air conditioner blow out
Air-flow have good guiding function, to rectification block 1 make air-flow change direction it is more soft, blow out air-flow flow velocity become
Change is more gentle, avoids abnormal sound occur because blowing out air-flow velocity change dramatically through air outlet.
Preferably, rectification block 1 is towards inclined-plane and the lower frame 21 inside air-duct spiral case 2 towards the side phase of upper side frame 22
It hands over, thus when the air flow contacts of air conditioner blowout are to rectification block 1, air-flow can be directly with 1 contact of incline plane of rectification block and by this
Rectifying block 1 drains and changes direction, to further alleviate the air-flow wind speed generation drastic change for flowing through rectification block 1, further subtracts
There is the intensity of abnormal sound because of air-flow velocity change dramatically in weak outlet air air-flow.
Further, with reference to Fig. 2, the low regime cross sections S are triangle, and rectification block 1 is towards oblique inside air-duct spiral case 2
Face is parallel with the boundary face of low regime S towards upper side frame 22, and the air-flow so as to flow through low regime S is rectified block 1 and draws
After stream, the direction of air-flow (i.e. rectification block 1 towards the inclined-plane extending direction inside air-duct spiral case 2) and low regime S are towards top
The boundary face of frame 22 is parallel, to which all air-flows in the S of low regime are just carried out drainage acceleration by rectification block 1, while also keeping away
Exempt to improve the probability for condensation occur because rectification block 1 puffs away due to stream is excessively stopped to air conditioner.
Preferably, with reference to 2, rectification block 1 is more than to the distance of inclined-plane peak to lower frame 21 inside air-duct spiral case 2
Equal to the distance of low regime S peaks to lower frame 21, to which rectification block 1 draws by all air-flows in the S of low regime
Under the premise of stream accelerates, side of the rectification block 1 away from the inside of air-duct spiral case 2 stops the gas after the drainage of 1 inclined-plane of rectified block
It flows back to and flow to air outlet W, rectification block 1 is to flowing through the gas flow speeding best results of low regime S, eliminating or alleviating surge phenomenon most
It is good.
Further, referring to Figure 1 and Figure 3, low regime S is by the positive and negative 15 degree of areas radiated of eccentric vertical line on lower frame 21
Domain, the bias vertical line are using the center of the eccentric vortex of air-conditioned wind tunnel as basic point, to vertical line made by 21 place plane of lower frame.
Using this scheme, rectification block 1 is best to flowing through the gas flow speeding best results of low regime S, eliminating or alleviating surge phenomenon.
In addition, rectification block 1 is fixedly connected or is integrally formed with lower frame 21, i.e., rectification block 1 can the direct company of fixation
