Embodiment
It is below in conjunction with the accompanying drawings, right by embodiment in order to understand in order to preferably explain the utility model
The utility model is described in detail.
Embodiment one
Referring to Figures 1 and 2, the present embodiment provides one kind ventilation noise-reducing window, the ventilation noise-reducing window to include window frame 11, window frame 11
Glass 9 is inside provided with, the opening that can install ventilation denoiser is cut with glass 9, glass 9 passes through connector 7 and ventilation noise reduction
Device is tightly connected.Wherein, divulge information denoiser structure specifically as described below.
Ventilation denoiser includes housing 1, and housing 1 is internally provided with sound absorption structure, and the surface of housing 1 offers air inlet
5 and air outlet 6, housing 1 be internally provided with wind turbine 3, wind turbine 3 is connected by wind inlet channel 4 with air inlet 5, and wind turbine 3 is by going out
Wind air passage 10 is connected with air outlet 6.
In the ventilation denoiser of the present embodiment, the shape of housing 1 does not do specific requirement, can during actual use
With according to actual installation Environment Design.In order to reduce assembly cost, save installation time, the shape of housing 1 preferably to be square,
The denoiser that will more easily divulge information is installed on the glass 9 of window.The specific size of housing 1 does not require, as long as can guarantee that
Sound absorption structure is set inside it, and wind turbine 3 can run well.
In the ventilation denoiser of the present embodiment, in order to which the noise-reducing window that ensures to divulge information has sufficient daylighting, housing 1 uses printing opacity
Material is made, and light transmissive material can be transparent, can also be translucent, and housing 1 is preferably polymethyl methacrylate
(PolymethylMethacrylate, referred to as PMMA) material, PMMA have excellent translucency, chemical stability and resistance to
Hou Xing, is a kind of good transparent accessory.
In the ventilation denoiser of the present embodiment, produced strong to eliminate disengaging air passage generation vibration in ventilation process
Noise, the inner wall of housing 1 are provided with the Felt of several surface concave-convex surfaces, and concavo-convex stereochemical structure can be lifted logical
The noise reduction of wind denoiser, can also set multiple sound-absorbing hole on Felt, and the shape of sound-absorbing hole is unlimited, can be circle
The shapes such as hole, rectangular opening or diamond hole.The inner wall that Felt can be close to housing 1 is set, and can also be consolidated by fixing piece part
It is scheduled on the inner wall of housing 1, the arrangement mode of Felt is unlimited, can arrange along the inner wall of housing 1, can be fixed on housing
1 inside and enclosing is set, and can also be arranged in column.In order to reduce installation cost, installation time is saved, directly by Felt
The inner wall for being close to housing 1 is set.
Above-mentioned Felt includes sound-absorbing material layer 2, and sound-absorbing material layer 2 can select acoustic absorptivity to be more than or equal to 0.79
Sound-absorbing material make.Acoustic absorptivity is the acoustic energy that material absorbs with inciding the ratio between total acoustic energy on material.Work as incident acoustic wave
When can be completely reflected, acoustic absorptivity 0, indicates no sound absorption；When incident acoustic wave is not reflected completely, acoustic absorptivity
For 1, expression is absorbed completely.Between 0 and 1, acoustic absorptivity value is bigger for general material or the acoustic absorptivity of structure, represents to inhale
Acoustic energy power is better, it is the current characterization most common parameter of sound absorbing capabilities.In fact, the acoustic absorptivity of all material is all between 0
And between 1, that is, can not possibly all reflect, it is also not possible to all absorb.The ventilation denoiser of the present embodiment, acoustic absorptivity are big
In can further increase acoustically effective equal to 0.79.
Sound-absorbing material of the above-mentioned acoustic absorptivity more than or equal to 0.79 can select harmless sound absorption cotton, such as egg
Cotton.Egg cotton is that the corrugated sponge of convex-concave is presented in a kind of one side formed by equipment specially treated, it is internal full of tiny
Gap and half open-celled structure, can largely absorb the acoustic wave energy of injection, attenuation is played to sound wave, reduce the interference of reflected sound
With echo, improve the purity of sound.The cotton that absorbs sound has the hole and bubble of a large amount of inside and outside unicom, when sound wave incident to wherein when,
Air vibration in gap can be caused, due to the viscosity resistance of air, the friction of air and hole wall, converts quite a few acoustic energy
It is consumed into thermal energy.In addition, when air adiabatic compresses, heat exchange constantly occurs between air and hole wall, due to heat transfer
Effect, also can make a part of acoustic energy change into thermal energy, so as to reach the effect for also having sound-absorbing to the buffering of sound.The effect of sound-absorbing
Size, the thickness of whole cotton with perforate is related, and i.e. enabled sound-absorbing can only also inhale sub-fraction if too thin, and in addition perforate is unsuitable
It is excessive, it is excessive there is no sound-absorbing effect, cross slight drag too loud noise and cannot get through.Sound absorption cotton can sound-absorbing can also play
The action of original sound, because meeting and sound absorption cotton produce friction when sound is by sound-absorbing, can have been buffered one by soundproof effect
Under, and then lower the penetration power of original sound.Certainly, sound-absorbing material is also an option that other acoustic absorptivities are more than or equal to 0.79
Other materials, for example, at least one in porous ceramics, air-permeable layer yarn, multi-layer silk screen, glass felt and rotary glass panel
Kind.
In the ventilation denoiser of the present embodiment, in order to further lift the soundproof effect of ventilation denoiser, 4 He of wind inlet channel
The inner wall at least one air passage in exhaust air flue 10 is provided with sound-absorbing material layer 2, the sound-absorbing material of sound-absorbing material layer 2 can with it is upper
It is identical to state the sound-absorbing material of 1 inner wall of housing, the materials such as cotton described above that absorb sound.
