Description
Technical field
It the utility model is related to sound field process field, the air channel of especially a kind of effectively drop low wind noise and air outlet grille.
Background technology
With the raising of national life level, further raising of the people to environmental quality requirement, especially to sound field
It is required that harsher recording studio environment.Wall sound insulation at present has been done highly developed and perfect.Sound insulation drop under this environment
Make an uproar processing short slab be air exchange system noise elimination noise reduction problem.Therefore each side factor in small space air exchange system there has also been more
High requirement, but air exchange system air-supply dynamics Relatively centralized in small space at present, people's physical efficiency is substantially perceived, and noise is deposited always
, it is difficult to eliminate.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is：It is extraneous to provide one kind effectively drop low wind noise, isolation
The air outlet grille of noise.
In order to solve the above-mentioned technical problem, it is of the present utility model another object is that：A kind of effectively drop low wind noise, isolation are provided
The air channel of ambient noise.
Technical scheme is used by the utility model：A kind of air outlet grille of effectively drop low wind noise, the grid bag
Horizontal and vertical grizzly bar is included, is arranged at intervals and is parallel to each other between the horizontal grizzly bar, between longitudinal grizzly bar
It is arranged at intervals and angle is provided between adjacent grill, grizzly bar of the longitudinal grizzly bar perpendicular to transverse direction.
Further, the angle between longitudinal grizzly bar is 3-15 degree.
Another technical scheme is used by the utility model：A kind of air outlet grille using above-mentioned effectively drop low wind noise
Air channel, include wind inlet channel, one end of the wind inlet channel is provided with air inlet, and the other end of the wind inlet channel is set
There is air outlet, the air outlet grille is arranged at air outlet, in the wind inlet channel between the air inlet and air outlet grille also
It is provided with multiple dividing plates.
Further, the area of the multiple dividing plate is the 1/2~2/3 of wind inlet channel cross section.
Further, the multiple dividing plate Heterogeneous Permutation, for making the air-flow in wind inlet channel form the flow path of complications.
Further, it is to be detachably connected between the air outlet grille and air outlet.
Further, the air inlet is provided with flange-interface, for accessing Fan pipeline.
The beneficial effects of the utility model are：By setting different angles of inclination to the grizzly bar of grid, when air-supply passes through
During grid, cause air flow through grizzly bar and change flow direction, cell structure compared with the prior art, direction when sending out air-flow is more
Diverging, so that air-supply is softer, noise is smaller.
Another beneficial effect of the present utility model is：Dividing plate is set by the ad-hoc location in air channel, makes gas in air channel
Stream reduces kinetic energy, the static pressure dynamic pressure of blower fan being transformed into air channel, by reducing distinguished and admirable disorder by Tortuous flow back and forth
Low wind noise drops in degree and wind speed；After the noise of blower motor is by the stop of several layers of dividing plate, absorbing simultaneously, reached by grid
Extraneous noise significantly reduces；And the grid for combining air outlet further reduces noise.

Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
A kind of air outlet grille of effectively drop low wind noise, the grid include horizontal and vertical grizzly bar, the transverse direction
Grizzly bar between be arranged at intervals and be parallel to each other, be arranged at intervals between longitudinal grizzly bar and be provided with folder between adjacent grill
Angle, grizzly bar of the longitudinal grizzly bar perpendicular to transverse direction.
Existing grid is generally as shown in figure 1, be to fix and be arranged in parallel between grizzly bar；Also having will wherein in partial grid
The grizzly bar in one direction is arranged to rotatable, but grizzly bar rotates simultaneously when rotated, therefore same side is still directed towards during air-out
To.And in the utility model, horizontal grizzly bar makees identical setting with existing grid, i.e., is arranged at intervals between horizontal grizzly bar
And be parallel to each other, the plane where horizontal grizzly bar and grid plane perpendicular；The grizzly bar of longitudinal direction is then different from existing grid work
Setting, relative to plane where original longitudinal grizzly bar and the setting of grid plane perpendicular, in longitudinal phase in the utility model
Angle is then provided between adjacent grizzly bar, its transverse cross-sectional view is as shown in Figure 2.
It is further used as preferred embodiment, the angle between longitudinal grizzly bar is 3-15 degree.
As shown in Fig. 2 the inclined angle of longitudinal grizzly bar in an intermediate position is minimum, it is inclined closer to both ends, grizzly bar
Angle is bigger, and when air-supply passes through grid, air-flow changes flow direction by grizzly bar, cell structure compared with the prior art, makes
Direction when air-flow is sent out more dissipates, so that air-supply is softer, noise is smaller.
Reference picture 3, it is further used as preferred embodiment, a kind of air outlet grille using above-mentioned effectively drop low wind noise
Air channel, include wind inlet channel, one end of the wind inlet channel is provided with air inlet, and the other end of the wind inlet channel is set
There is air outlet, the air outlet grille is arranged at air outlet, in the wind inlet channel between the air inlet and air outlet grille also
It is provided with multiple dividing plates.
The side view of reference picture 4 and Fig. 5 top views, it is further used as preferred embodiment, the area of the multiple dividing plate
For the 1/2~2/3 of wind inlet channel cross section；It is unfavorable for extending the length in air current flow path if dividing plate area is too small, if every
Plate suqare is excessive, may cause the noise that the excessive generation of air pressure is extra in air channel.
It is further used as preferred embodiment, the multiple dividing plate Heterogeneous Permutation, for making the air-flow in wind inlet channel
Tortuous flow path is formed, its path is as shown in the direction of arrow in Fig. 5, and air-flow reduces dynamic by Tortuous flow back and forth in air channel
Can, the static pressure dynamic pressure of blower fan being transformed into air channel, low wind noise drops by reducing distinguished and admirable disorderly degree and wind speed；Simultaneously
After the noise of blower motor is by the stop of several layers of dividing plate, absorbing, extraneous noise is reached by grid and significantly reduced；Test knot
Fruit shows that behind air channel of the present utility model noise can reduce more than 20dB.
Preferred embodiment is further used as, is to be detachably connected between the air outlet grille and air outlet.
Preferred embodiment is further used as, the air inlet is provided with flange-interface, for accessing Fan pipeline.
Above is preferably implement to be illustrated to of the present utility model, but the utility model is created and is not limited to institute
State embodiment, those skilled in the art can also make a variety of etc. on the premise of without prejudice to the utility model spirit
With conversion or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
