Accompanying drawing explanation
By referring to the description of accompanying drawing to the embodiment of the present invention, above-mentioned and other objects of the present invention, feature and advantage will be more clear, in the accompanying drawings:
Fig. 1 is board-like denoising structure schematic diagram;
Fig. 2 is board-like denoising structure schematic cross-section.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, various embodiment of the present invention is described in more detail.In various figures, identical element adopts same or similar Reference numeral to represent.For the sake of clarity, the various piece in accompanying drawing is not drawn in proportion.
Board-like denoising structure provided by the invention is mainly used in conditioner such as air-conditioner outdoor unit and reduces noise, particularly there is good noise reduction to low-frequency range noise, and the board-like denoising structure of the present invention can save device interior space, and can not have an impact to associated components.Below in conjunction with specific embodiment, the board-like denoising structure of the present invention is described in detail.
As shown in Figure 1, 2, the board-like denoising structure of the present invention comprises sound-absorbing part 1 and thin plate 2, and described thin plate 2 is fixed on described sound-absorbing part 1, and preferably, described thin plate 2 is fixed on described sound-absorbing part 1 by the mode of sticky note.Described sound-absorbing part 1 is for having the material of suction function, preferably, described sound-absorbing part 1 is the opening foamed material of skeleton structure melmac, there is certain elasticity, and it is inner containing aperture, can sound wave be absorbed, and can propagate by sound wave the energy consuming sound wave therein, thus realize the object of noise reduction.Described thin plate 2 is metallic plate, is preferably corrosion resistant plate.
Described sound-absorbing part 1 is tabular, and preferably, the thickness of described sound-absorbing part 1 is 15 ~ 25mm, described thin plate 2 thickness is 0.5 ~ 1mm, on the first surface being fixed on described sound-absorbing part 1 that described thin plate 2 and the first surface of described sound-absorbing part 1 are fitted, preferably, described thin plate 2 is provided with multiple fixing point 3, and described fixing point 3 is not set in the edge of described thin plate 2, described in described fixing point 3 place, thin plate 2 is fixed on the first surface of described sound-absorbing part 1 to put fixing mode, to ensure that the hole on described sound-absorbing part 1 can not by complete shutoff, avoid impacting the sound absorption qualities of described sound-absorbing part 1, further, at described fixing point 3 place, described thin plate 2 is fixed on the first surface of described sound-absorbing part 1 by the mode of sticky note.Preferably, the area of described thin plate 2 is less than the rectangle corrosion resistant plate of the area of the first surface of described sound-absorbing part 1, to ensure that described sound-absorbing part 1 can absorb sound wave, and rectangle corrosion resistant plate has abundant simple harmonic oscillation frequency when edge is completely free, minimumly reach several hertz, resonate when low frequency range noise sound wave is consistent with the simple harmonic oscillation frequency of described thin plate 2, can be good at absorbing low-frequency sound wave, further, have on certain flexible described sound-absorbing part 1 because described thin plate 2 is fixed on, the energy of itself and acoustic resonance is damped to be consumed.
The board-like denoising structure of the present invention carries out noise reduction mainly through described sound-absorbing part 1 pair of high band noise, and logical described thin plate 2 of crossing resonates with low frequency range noise, and then carries out noise reduction to low frequency range noise.
The board-like denoising structure of the present invention is arranged in air-conditioner outdoor unit:
Described board-like denoising structure mainly carries out noise reduction to the noise that the compressor in air-conditioner outdoor unit produces.The second face relative with the first surface being provided with described thin plate 2 on described sound-absorbing part 1 is fixed on inside the shell of off-premises station, the compressor of described thin plate 2 near described off-premises station inside and miscellaneous part.In order to obtain best noise reduction, increase the setting area of described board-like denoising structure in the shell of described off-premises station as far as possible.The high frequency sound wave of the noise that described compressor sends is absorbed by described sound-absorbing part 1, and reflects therein, propagates, and in communication process, the energy of sound wave is consumed; Meanwhile, can not resonate at the low-frequency range sound wave of described sound-absorbing part 1 internal consumption and described thin plate 2, its energy is consumed, thus realizes the object of noise reduction.
Board-like denoising structure provided by the invention is arranged on the shell of air-conditioner outdoor unit, not with produce the compressor of noise and directly contact, be not only convenient to the space installing but also can save enclosure.Simultaneously, because described board-like denoising structure does not directly contact with described compressor and connecting line thereof, so described compressor or pipeline and board-like noise-reducing structure can be avoided to collide generation abnormal sound, also can avoid rising and problem that described sound-absorbing part 1 is ignited because compressor triple line connects anti-ballistic its temperature that causes.And the condensation that the pipeline of described off-premises station surface produces can not be absorbed by described board-like denoising structure, can not be formed and freeze, so can not impact described board-like denoising structure on described board-like denoising structure.
Should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
