Fig. 1 is the sketch map in air conditioning for automobiles air channel in the prior art;
The schematic representation of apparatus that is used to reduce air conditioning for automobiles air channel noise that Fig. 2 provides for the embodiment of the invention
The sketch map in the air conditioning for automobiles air channel that Fig. 3 provides for the embodiment of the invention.
The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the present invention protects.
The embodiment of the invention provides a kind of device that is used to reduce air conditioning for automobiles air channel noise; As shown in Figure 2; Comprise: arc 21, be located at tubular body 23 on the said arc 21, that have a plurality of holes 22, and be set in the toroidal membrane 24 on the said tubular body 23; Said dividing plate 24 is fixed in the said air conditioning for automobiles air channel (not shown among Fig. 2); The edge of said arc 21 is towards said dividing plate 24.
In order clearly to describe the operation principle of said apparatus; Define here arc more than 21, dividing plate below 24 and tubular body 23 outer parts be the first noise elimination road; Definition arc 21 or more, dividing plate 24 below and the parts in the tubular body 23 be middle noise elimination road, defining dividing plate 24 above tubular bodies 23 interior parts is the second noise elimination road.
The air that flows through the air conditioning for automobiles air channel flows along the direction of arrow shown in Fig. 2.At first touch arc 21 because the edge of arc 21 is towards dividing plate 24, so air through behind the curved surfaces of arc 21 by shunting equably, the air after the shunting moves to first sound channel along the curved surfaces of arc 21; The air that gets into first sound channel receives stopping of dividing plate 24, noise elimination road in the middle of getting into through the hole on the tubular body 23 22; After the air-flow that gets into from hole 22 met middle noise elimination road, the sound wave of generation was interfered each other, thereby subdues the partial noise source.
In addition, because dividing plate 24 can stop air upwards,, can make the air that gets into middle noise elimination road smoothly smooth and easy through the buffering of dividing plate 24.
The air in noise elimination road gets into the second noise elimination road in the middle of getting into, and is assigned to the branch air channel of air conditioning for automobiles through the second noise elimination road, again through dividing the air channel to get in the driver's cabin.
The device that is used for reducing air conditioning for automobiles air channel noise that the embodiment of the invention provides; Owing to be provided with arc 21 and dividing plate 24; And the edge of arc 21 is towards dividing plate; Make the air that flows through the air conditioning for automobiles air channel by can be after the shunting equably, and the sound wave energy of the air-flow generation through hole 22 be interfered each other, thereby air noise when flowing through the air conditioning for automobiles air channel is significantly reduced through a plurality of holes 22 that are provided with on the tubular body 23.
