The present embodiment is realized the basic principle of compressor noise-reduction as follows by said structure:
Denoising device in air-conditioner outdoor unit utilizes the some micropores air layer external with this noise reduction shroud on noise reduction cover body to form a plurality of Hai Muhuozhi resonators in parallel, when compressor resonant frequency is consistent with system resonance frequency, air through noise reduction cover body micropore produces fierce vibration friction, thereby strengthened sound-absorbing benefit, formed absworption peak, made the aobvious acute decay of acoustic energy; Owing to adopting micropore, micropore is thin and close, so acoustic resistance is large and acoustic mass is little, therefore the difference of acoustic resistance and acoustic mass is larger, does not need to increase Sound-proof material etc. and just can form good sound-absorbing effect.
From the above, the structural design that the present embodiment is provided with the denoising device of micropore is suitable for broadband absorption, can effectively absorb compressor different frequency section noise, therefore can substitute traditional Sound-proof material and sound-absorbing effect better, and because the micropore plate material volume of noise reduction cover body is little, quality is light, thereby can reduce costs.
In sum, compared to existing technology, the present embodiment passes through such scheme, utilize the some micropores air layer external with noise reduction shroud on noise reduction cover body to form a plurality of Hai Muhuozhi resonators in parallel, be suitable for the noise that broadband wave absorption principle absorbs the different frequency section of compressor generation, solved the narrow problem of traditional Sound-proof material sound-absorbing frequency band; Because the micropore plate material of noise reduction cover body is thin and materials are few, low price, can significantly reduce the cost; In addition,, because micropore plate material is simple in structure, be convenient to production and processing and produce assembling, so efficiency is high, can promote air-conditioner quality, easy to installation and maintenance.
As shown in figure 10, Figure 10 is the schematic diagram after the side plate 20 of the utility model air-conditioner outdoor unit the second embodiment denoising device launches.In the present embodiment, the difference of noise reduction cover body and above-mentioned the first embodiment is, in the present embodiment, noise reduction cover body is provided with some slit plates, and as a kind of embodiment, the thickness of described noise reduction cover body is 0.2-1mm; The gap rate of described noise reduction cover body can be 0.5%～5%, and the width of the slit 61 of described noise reduction cover body can be 0.5～5mm.The seam length of this slit 61 can be selected different length or equal length.
Its principle of noise reduction is: the air column that is equivalent to quality in slit 61 forms a vibrational system with the outer cavity that is equivalent to spring of device, when incident acoustic wave frequency approaches the fixed frequency of system, i.e. and RESONANCE ABSORPTION peak value.Although the noise reduction of slit 61 is compared micropore slightly almost, it is easy to process, is convenient to implement.
It should be noted that, in other embodiments, noise reduction cover body also can be provided with some micropores and slit simultaneously, and such as cover plate 10 is for being provided with the sheet material of some micropores, side plate 20 is for being provided with the sheet material of some slits; Or cover plate 10 is for being provided with the sheet material of some slits, side plate 20 is for being provided with the sheet material of some micropores.In addition, side plate 20 also can be assembled by plurality of plates, does not repeat them here.
Above are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or flow process conversion that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
