Through having seted up a plurality of through-holes on with soundproof cotton's the puigging, can effectually absorb and completely cut off to the specific noise frequency that the compressor sent to satisfy the sound quality requirement of air conditioner product.
Description
Technical field
The utility model relates to field of air conditioning, in particular to a kind of cooler compressor Sound-proof material and air-conditioner.
Background technology
The noise of air-conditioner outdoor unit is mainly derived from blower fan and compressor, noise control to blower fan is mainly by improving blade profile, the main noise reduction technology means of compressor are to realize noise reduction by the principle that stops Acoustic Wave Propagation, namely wrap up Sound-proof material on compressor, intercept or absorb compressor to the acoustic wave energy of extraradial each frequency band, to reach the effect that reduces the off-premises station overall noise.Existing Sound-proof material mainly contains following structure: puigging is rubber damping class material, and sound absorbing layer is fiber felt class material, by the combination of sound-absorbing material and acoustic material, forms the combination Sound-proof material of the various different numbers of plies.
The noise non-selectivity of existing Sound-proof material to CF, the noise-reduction effect of some frequency noise that compressor is sent is undesirable, is difficult to satisfy the sound quality requirements of air-conditioning products.
The utility model content
The utility model aims to provide a kind of cooler compressor Sound-proof material and air-conditioner, by offering a plurality of through holes on the puigging with Sound-proof material, the specific frequency noise that can effectively send for compressor absorbs and completely cuts off, thereby satisfies the sound quality requirements of air-conditioning products.
The utility model provides a kind of cooler compressor Sound-proof material, comprises puigging, has a plurality of through holes on described puigging.
Preferably, also comprise sound absorbing layer, described sound absorbing layer and puigging interconnect.
Preferably, the diameter of described through hole is for typically having a diameter between 2mm to 8mm, and the through hole gross area accounts for below 20% of the described puigging gross area.
Preferably, described through hole is shaped as circle and/or square.
Preferably, described sound absorbing layer is fiber felt class material, and described puigging is rubber damping class material.
According on the other hand of the present utility model, the utility model also provides a kind of air-conditioner, comprise compressor and compressor Sound-proof material, described compressor Sound-proof material is aforementioned any compressor Sound-proof material, and described compressor Sound-proof material is coated on the surface of described compressor.
According to cooler compressor Sound-proof material of the present utility model, comprise puigging, have a plurality of through holes on puigging.By offering a plurality of through holes on the puigging with Sound-proof material, can selectively absorb for the noise of CF with isolated, reduce compressor noise, promote air-conditioning products sound quality.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the utility model cooler compressor Sound-proof material the first embodiment; And
Fig. 2 shows the structural representation of the utility model cooler compressor Sound-proof material the second embodiment.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Fig. 1 shows the structural representation of the utility model cooler compressor Sound-proof material the first embodiment, and in the present embodiment, the Sound-proof material that provides is coated on the surface of cooler compressor cylinder body, the noise that produces when working for reducing compressor of air conditioner.As shown in Figure 1, the cooler compressor cotton of the present embodiment is comprised of individual layer puigging 1, and puigging 1 is rubber damping class material, has a lot of micro-through-holes on puigging 1.The shape of through hole can be circle.
Fig. 2 shows the structural representation of the utility model cooler compressor Sound-proof material the second embodiment, as shown in Figure 2, inter-adhesive puigging 1 drawn together by the cooler compressor bale of cotton of the present embodiment and sound absorbing layer 2 forms, sound absorbing layer 2 is fitted with the surface of compressor of air conditioner cylinder body, thereby and encloses around compressor of air conditioner one surface that is coated on air-conditioner compressor of air conditioner cylinder body.Sound absorbing layer 2 can be the made felt layers of fiber felt class material, and puigging 1 can be the made rubber layer of rubber damping class material.Have a lot of through holes on puigging 1.
According to the acoustics communication theory, the perforation puigging is the combination of a plurality of Helmholtz resonators, and when the incident sound wave frequency was consistent with the resonant frequency of perforation puigging, the air of perforation puigging felt neck produced fierce vibration friction, strengthened sink effect, acoustic energy is significantly decayed; If the material of puigging is rubber damping material, the noise band of absorption is widened.
The frequency noise that absorbs can be calculated by following formula:
F in following formula
0Be the frequency noise that will eliminate, c is the velocity of sound (cm/s), and P is the punching rate (%) of puigging, and t is the thickness (cm) of puigging, and d is penetration hole diameter (cm), and L is compressor chamber air layer thickness (cm) after puigging.
After after described puigging, the compressor chamber air layer thickness refers to that specifically puigging wraps compressor and pipeline, the distance of puigging and compressor cavity surrounding sheet metal component.
Can draw from above formula, if P=0.05, t=2mm, d=5mm, L=50mm can get best noise reduction frequency and is: f
0Near section=590Hz.
More preferably, the punching rate of puigging (being the ratio that the through hole gross area accounts for the described puigging gross area) should be below 20%, because when punching rate greater than 20% the time, the acoustic mass of perforation puigging is very little, its acoustics effect reduces, the puigging of boring a hole this moment has not only belonged to sound absorption structure as armour layer, and noise reduction is not good.Preferably, at 100-4000Hz, the sound insulation bed thickness is generally 1-2mm due to the common noise peak frequency of cooler compressor, after puigging the compressor chamber air layer thickness be several millimeters to 100mm, easily draw according to above-mentioned formula, what penetration hole diameter was more excellent can be set between 2-8mm usually.
The utility model also provides a kind of air-conditioner, comprises compressor and aforesaid compressor Sound-proof material.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
1, use the novel cooler compressor Sound-proof material of this enforcement to absorb and to completely cut off for specific frequency noise, than common Sound-proof material, better noise reduction is arranged, thereby satisfy the sound quality requirements of air-conditioning products.
2, the novel cooler compressor Sound-proof material of this enforcement owing to having used perforation structure, can also be saved the part material cost.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; the utility model can have various modifications and variations; as relate to the Sound-proof material that uses this enforcement new structure sound insulating layer; no matter the Sound-proof material number of plies how, how material stack order; material thickness how, within all should being included in protection domain of the present utility model.
