Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of protection of the invention.
The embodiment of the present invention provides a kind of device for reducing vehicle air conditioner duct noise, as shown in Figure 2, comprise: arc 21, be located on described arc 21, that there is multiple hole 22 tubular body 23, and be set in the toroidal membrane 24 on described tubular body 23; Described dividing plate 24 is fixed in described vehicle air conditioner duct (not shown in Fig. 2); The edge of described arc 21 is towards described dividing plate 24.
In order to clearly describe the operation principle of said apparatus, the part defined outside arc more than 21, dividing plate less than 24 and tubular body 23 is the first noise elimination road herein, part in definition arc more than 21, dividing plate less than 24 and tubular body 23 is middle noise elimination road, and the part in definition dividing plate more than 24 tubular body 23 is the second noise elimination road.
Flow through the air of vehicle air conditioner duct along the direction of arrow flowing shown in Fig. 2.First touch arc 21, because the edge of arc 21 is towards dividing plate 24, therefore air is shunted equably after the curved surfaces of arc 21, and the air after shunting moves along the curved surfaces of arc 21 to the first sound channel; The air entering the first sound channel is subject to the stop of dividing plate 24, enters middle noise elimination road by the hole 22 on tubular body 23; After the air-flow entered from hole 22 meets middle noise elimination road, the sound wave of generation is interfered mutually, thus abatement partial noise source.
In addition, because dividing plate 24 can stop air upwards, through the buffering of dividing plate 24, the air smooth entering middle noise elimination road can be made.
The air entering middle noise elimination road enters the second noise elimination road, is assigned to point air channel of air conditioning for automobiles, then is entered in driver's cabin by a point air channel by the second noise elimination road.
In the device for reducing vehicle air conditioner duct noise that the embodiment of the present invention provides, owing to being provided with arc 21 and dividing plate 24, and the edge of arc 21 is towards dividing plate, the air making to flow through vehicle air conditioner duct is by the multiple holes 22 by tubular body 23 is arranged after shunting equably, and can mutually be interfered by the sound wave that the air-flow of hole 22 produces, thus air noise when flowing through vehicle air conditioner duct is significantly reduced.
In the device for reducing vehicle air conditioner duct noise that above-described embodiment describes, dividing plate 24 can be arc, and the edge of dividing plate 24 is towards arc 21.Dividing plate 24 can be fixed in vehicle air conditioner duct, simultaneously for blocks air, when dividing plate 24 be arc and the edge of dividing plate 24 towards arc 21 time, the air shunted via arc 21 is subject to the stop of dividing plate 24 curved surfaces, and air can be made to become smooth more.
It should be noted that: the shape of dividing plate 24 is not limited to the arc shown in Fig. 2, also can be that other known to those skilled in the art can realize the fixing and shape of blocks air effect.
As shown in Figure 2, dividing plate 24 is preferably placed on the position of 1/2 height of tubular body 23, make the length in middle noise elimination road identical with the length in the second noise elimination road, the air entering the second noise elimination road like this from middle noise elimination road enters a point air channel by as far as possible many holes 22, serve the effect of smooth flow of gas, therefore, the noise produced when air flows in air-conditioning duct can be reduced further.
In the device for reducing vehicle air conditioner duct noise that above-described embodiment describes, the structure that arc 21, tubular body 23 and dividing plate 24 can be integrated, such design is to make apparatus structure firm, and can firmly be fixed in air channel, do not loosen, and the cost manufacturing this device can be saved.
When the cross sectional shape of vehicle air conditioner duct is circular, in the device for reducing vehicle air conditioner duct noise that above-described embodiment describes, the distance between arc 21 edge and described tubular body 23 outer surface can be preferably 1/6 of described vehicle air conditioner duct internal diameter; Distance between tubular body 23 outer surface and described vehicle air conditioner duct inner surface can be preferably 1/3 of described vehicle air conditioner duct internal diameter.Such design can optimize the effect of air flow.
In a kind of device for reducing vehicle air conditioner duct noise that above-described embodiment describes, the shape of hole 22 can be set to ellipse, distance between adjacent described hole 22 is preferably 2mm-5mm, such design can reduce the stop of tubular body 23 pairs of air, thus can obtain good noise reduction further.
