Further, in the ventilating sound-proof device of the present embodiment, air channel 4 is noise elimination air channel 4.Above-mentioned noise elimination air channel 4 is meeting
In the case of requirement, existing any noise elimination air channel 4 can be selected.Specifically, in the present embodiment, in air channel 4
Wall sets sound-absorbing material 2, and sound-absorbing material 2 can select porous ceramics, air-permeable layer yarn, multi-layer silk screen, glass felt and centrifugation
At least one of glass panel.
In the present embodiment, the inwall of casing 1 sets one layer of sound-absorbing material 2, and one layer of sound-absorbing material 2 is also provided with air channel 4,
Two layers sound-absorbing material 2 is used so that blower fan 3 is when ventilation, and soundproof effect further improves.
Further, air inlet 5 and air outlet 6 are separately positioned on the two neighboring surface of casing.So setting can be with
So that the distance between air inlet 5 and air outlet 6 increase (most notable of which is the length increase in air channel 4), and then cause sound
Propagation distance increase of the sound in sound-absorbing material, propagation distance increase of the sound in sound-absorbing material, can not only cause casing 1
On sound-absorbing material 2 and the sound-absorbing material being arranged on the inwall of air channel 4 the increase of sound-absorbing material area, and enable to sound
Sound is when propagating, the increase of sound absorption time, and then common so that the efficiency that the mechanical shock of sound is converted into heat energy is carried
Height, namely absorption efficiency are improved.
Further, in the ventilating sound-proof device of the present embodiment, the acoustic absorptivity of sound-absorbing material 2 is more than or equal to 0.79.It is above-mentioned
Acoustic absorptivity is the acoustic energy of material absorption with inciding the ratio between total acoustic energy on material.When incident acoustic energy is completely reflected, inhale
Sonic system number is 0, indicates no sound absorption；When incident acoustic wave is not reflected completely, acoustic absorptivity 1, expression is inhaled completely
Receive.Between 0 and 1, acoustic absorptivity value is bigger for general material or the acoustic absorptivity of structure, represents that acoustical absorptivity is better, it is
The most frequently used parameter of sound absorbing capabilities is characterized at present.In fact, the acoustic absorptivity of all material is all between 0 and 1, that is, not
May all it reflect, it is also not possible to all absorb.
The ventilating sound-proof device of the present embodiment, acoustic absorptivity, which is more than or equal to 0.79, can further increase acoustically effective.Sound absorption
Sound-absorbing material of the coefficient more than or equal to 0.79 can select the harmless sound absorption cotton such as egg cotton.Egg cotton is by equipment
The corrugated sponge of convex-concave is presented in a kind of one side that specially treated is formed, and its inside is full of small spaces and half open-celled structure, energy
It is a large amount of to absorb the acoustic wave energy injected, attenuation is played to sound wave, the interference of reflected sound is reduced and echoes, improve the pure of sound
Degree.The cotton that absorbs sound has the hole and bubble of a large amount of inside and outside UNICOMs, when sound wave incident to wherein when, air in space can be caused to shake
It is dynamic, due to the viscosity resistance of air, the friction of air and hole wall, quite a few acoustic energy is changed into heat energy and is consumed.This
Outside, when air adiabatic compresses, heat exchange constantly occurs between air and hole wall, due to conduction of heat, can also make a part
Acoustic energy changes into heat energy, so as to which the buffering reached to sound also has the effect of sound-absorbing.The effect of sound-absorbing and the size of perforate, whole
The thickness of cotton is relevant, and i.e. enabled sound-absorbing can only also inhale sub-fraction if too thin, and perforate is unsuitable excessive in addition, excessive not have
Sound-absorbing effect, cross slight drag too loud noise and cannot get through.Sound absorption cotton can sound-absorbing can also play some soundproof effects because in sound
Sound produces friction by meeting when sound-absorbing and sound absorption cotton, the action of original sound can have been buffered, and then lowers original sound
The penetration power of sound.
Further, in the ventilating sound-proof device of the present embodiment, the surface of casing is provided with vibration damping sheet.Above-mentioned vibration damping sheet can be with
So that blower fan 3 when work, will not cause overall strong vibrations, so that being loosened between each part, installation strength
Weaken.
