Abstract
The utility model discloses a kind of noise reducing type blower fan airduct, the airduct includes an air outlet and an air inlet, side wall between the air outlet and the air inlet is the arcuation caved inward, and the diameter of the air outlet is more than the diameter of the air inlet, and dentation is provided with the air outlet.The airduct of the application can effectively reduce the noise that outlet air expansion and turbulent flow are produced, and energy consumption is greatly lowered.
Description
Technical field
The utility model is related to field of Environment Protection, more specifically, is a kind of noise reducing type blower fan airduct.
Background technology
It is inevasible in daily life and industrial production to use various blower fans.Blower fan is widely used, and quantity is big, mesh
Preceding its power consumption of the blower fan used accounts for the 10%-15% of national generating capacity.Blower fan is also produced while various benefits are brought
A large amount of noise pollution have been given birth to, and have wasted mass energy.
With the rapid development of economy, the raising of the environmental consciousness of people all the more, correspondence reduction noise, the requirement of energy-conservation
More and more higher.The noise pollution and energy-conservation for how reducing blower fan are our urgent problems.
Utility model content
Because prior art has above mentioned problem, the utility model proposes a kind of noise reducing type blower fan airduct, it can be effective
Solution problems of the prior art.
The utility model solves the above problems by the following technical programs：
A kind of noise reducing type blower fan airduct, the airduct include an air outlet and an air inlet, the air outlet with it is described
Side wall between air inlet is the arcuation caved inward, and the diameter of the air outlet is more than the diameter of the air inlet, and described
Dentation is provided with air outlet.
The caliber of a diameter of airduct at the most narrow place of airduct internal diameter；A diameter of caliber of the air outlet
1.2 again；1.1 times of a diameter of caliber of the air inlet；The air inlet to the most narrow place of the airduct internal diameter distance
For air inlet height, and the air inlet is highly 0.1 times of the caliber；The air outlet is most narrow to the airduct internal diameter
The distance at place is height at air outlet, and height is 0.15 times of the caliber at the air outlet.
The both sides of the air outlet are provided with outwardly directed fixed edge.
Because the airduct using above-mentioned technological means, the application can effectively reduce outlet air expansion and turbulent flow generation
Noise, and energy consumption is greatly lowered.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the present utility model；
Fig. 2 is a structural representation of the present utility model.
Embodiment
With reference to embodiment, the utility model is described in detail.
Referring to shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of an embodiment of the present utility model；Fig. 2 is that this practicality is new
One structural representation of type.
The noise reducing type blower fan airduct of the present embodiment include an air outlet 1 and an air inlet 2, the air outlet 1 with it is described
Side wall 3 between air inlet 2 is the arcuation caved inward, and the diameter D1 of the air outlet is more than the diameter D2 of the air inlet,
And dentation is provided with the air outlet 1.The diameter of air outlet is more than the diameter of air inlet, in air-out, and air-flow is in diffusion mode,
Reduce the noise that air expansion is produced.Exit is provided with dentation, the vortex of dentalation dispersion outlet, so as to reduce turbulence intensity
Noise is reduced, plays a part of drainage, it is possible to reduce the disorderly noise produced when gas flows out.
As shown in Fig. 2 the caliber D of a diameter of airduct at the most narrow place of airduct internal diameter；The diameter D2 of the air outlet
For 1.2 times of the caliber D；The diameter D1 of the air inlet is 1.1 times of the caliber D；The air inlet is to the airduct
The distance at the most narrow place of internal diameter is air inlet height H, and air inlet height H is 0.1 times of the caliber D；The air-out
Distance of the mouth to the most narrow place of the airduct internal diameter is that height Ht is the caliber D at height Ht, and the air outlet at air outlet
0.15 times.Dimensional fits gas expansion and increase, make the reduction of outlet air outlet slit speed, and guide air to spread, so as to reduce
Noise.
The both sides of the air outlet are provided with outwardly directed fixed edge L, and fixed edge L can be in order to airduct be consolidated
It is fixed.
Because the airduct using above-mentioned technological means, the application can effectively reduce outlet air expansion and turbulent flow generation
Noise, and energy consumption is greatly lowered.
It should be understood that these embodiments are merely to illustrate the utility model rather than limit scope of the present utility model.
In addition, it is to be understood that after the content of the utility model instruction has been read, those skilled in the art can make to the utility model
Various changes or modification, these equivalent form of values equally fall within the application appended claims limited range.
