Specific embodiment
The various embodiments that the present invention will be described in more detail that hereinafter reference will be made to the drawings.In various figures, identical element
It is indicated using same or similar appended drawing reference.For the sake of clarity, the various pieces in attached drawing are not necessarily to scale.
Denoising device provided by the invention, which is mainly used in, carries out sound-deadening and noise-reducing to equipment such as compressors, to reduce it in work
Noise during work, and the present invention has many advantages, such as that structure is simple, easy for installation and long service life.Below with reference to the present invention
The embodiment that denoising device is applied on compressor describes to its structure in detail.
As shown in Figure 1, 2, denoising device provided by the invention is tubular structure, and the denoising device is sleeved on generation noise
Equipment on the outside of, such as compressor, end face outer rim shape can be round, polygon or ellipse, or be other shapes,
It is determined according to the shape for generating noise equipment.The tubular structure includes external partition 1, internal partition 2 and sound absorbing layer 3, it is described in every
Plate 2 is arranged in the external partition 1, and the sound absorbing layer 3 is arranged between the external partition 1 and internal partition 2, it is preferable that described
Sound absorbing layer 3 is flannelette.The first hole 11 and the second hole 21, first hole 11 are respectively arranged on the external partition 1 and internal partition 2
Shape with the second hole 12 can be round, ellipse, polygonal hole or other arbitrary shapes, preferably circular hole.It is described
First hole 11 is correspondingly arranged with the second hole 12, and first hole 11 partly overlaps with the second hole 12, and the area of lap is institute
The 30%~60% of 12 area of the first hole 11 or the second hole is stated, (hereafter will do it detailed Jie to extend the propagation distance of sound wave
It continues).Preferably, the quantity in first hole 11 is greater than or equal to the quantity in second hole 21.In order to obtain preferable noise reduction
Effect.Preferably, the material of the external partition 1 and internal partition 2 is ABS plastic (Acrylonitrile Butadiene
Styrene plastic)。
In another preferred embodiment, cable-through hole 4 is additionally provided on the tubular structure, the cable-through hole 4 is in noise reduction
Through the external partition 1, the through-hole of internal partition 2 and sound absorbing layer 3 on device, the pipeline for compressor is passed in and out.
The working principle of denoising device of the present invention is：
Equipment in denoising device, for example, compressor generate noise sound wave enter the internal partition 2 on second
Hole 21, sound wave occur to enter the sound absorbing layer 3 after friction consumes portion of energy with hole wall in second hole 21, and sound wave exists
Consumption portion of energy is propagated in the sound absorbing layer 3, after passing through the sound absorbing layer 3, sound wave enters the first hole on the external partition 1
11, and friction occurs with the hole wall in first hole 11 and consumes part energy again.When first hole 11 and the second hole 21
When not on the same line being that first hole 11 and the second hole 21 partly overlap on Acoustic Wave Propagation direction, sound wave is by described the
Propagation distance between two the 21 to the first hole of holes 11 just will increase, i.e. sound wave propagation distance in the sound absorbing layer 3 increases, so
Noise reduction effect can be more preferable at this time.
As shown in figure 4, in one embodiment, denoising device provided by the invention is arranged in the outside of compressor 5, and
Its end is fixed on the rubber pad 51 of compressor fixed part, the pipeline of the compressor 5 is connected to institute through the cable-through hole 4
State (not shown) on compressor 5.The noise sound wave that issues passes through the on the internal partition 2 when the compressor 5 works
Two holes 21 enter the sound absorbing layer 3, when sound wave passes through second hole 21, since the friction of sound wave and hole wall can consume a part
The energy of sound wave；Sound wave during propagation in the sound absorbing layer 3 sound absorbing layer 3 can consume the energy of a part of sound wave,
Since second hole 21 and the first hole 11 only overlap, and sound wave is entered by second hole 21 again by first hole
11 outflows, so, partly overlapping second hole 21 and the first hole 11 extend propagation of the sound wave in the sound absorbing layer 3 away from
From, enable the sound absorbing layer 3 it is as much as possible consumption sound wave energy；Sound wave passes through after the sound absorbing layer 3 by described the
The friction of the hole wall in one hole 11, sound wave and first hole 11 can consume the energy of a part of sound wave again.By the second hole 21,
The energy of sound wave after sound absorbing layer 3 and the first hole 11 has been nearly consumed by, so noise can largely be cut down.
Denoising device provided by the invention utilizes first on the second hole 21, sound absorbing layer 3 and the external partition 1 on internal partition 2
Hole 11 carries out multistage reduction to acoustic wave energy, to consume acoustic wave energy to greatest extent.And second hole 21 and the first hole 11
The set-up mode to partially overlap increases propagation distance of the sound wave in the sound absorbing layer 3, further enhances acoustic wave energy
Consumption, can obtain best sound-deadening and noise-reducing effect.And denoising device assembly provided by the invention and installation are more convenient,
Improve production efficiency.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.
Finally it should be noted that：Obviously, the above embodiment is merely an example for clearly illustrating the present invention, and simultaneously
The non-restriction to embodiment.For those of ordinary skill in the art, it can also do on the basis of the above description
Other various forms of variations or variation out.There is no necessity and possibility to exhaust all the enbodiments.And thus drawn
The obvious changes or variations that Shen goes out are still in the protection scope of this invention.
