Abstract
The invention relates to a muffler of an air conditioning system. The muffler consists of four composite plates. Each composite plate comprises an inner muffling plate, a middle muffling plate and an outer metal plate. By adopting the composite muffling plates which respectively consist of an inner micropore plate, a sinusoidal micropore plate and the outer metal plate, a composite dual-layer sinusoidal muffling structure is effectively formed and the effect on muffling high-frequency, medium-frequency and low-frequency noises is excellent; the defects that the muffling frequency band is narrow and the muffling effect is poor in the prior art are overcome; by adopting the sinusoidal micropore plate, the thickness of the muffler can be decreased by one time of the thickness of a dual-layer micropore plate muffler; the structure of a wind pipe is simple and the wind pipe is convenient to assemble and install; and by adopting an assembling method, the problem that the transportation volume is too large is solved and the expenses are saved.
Description
Technical field
The present invention relates to a kind of air conditioner muffler, be specifically related to a kind of sinusoidal micropore composite plate muffler.
Background technology
The air-conditioning system great majority are applied in the hotel, in market or the office building, owing to be central control formula; Therefore will connect airduct as required, after air-conditioning system starts, cold or warm braw will be delivered to zones of different through airduct in a large number; And the noise of air of the mobile generation of wind will cause the pollution to environment; People's work or movable under these noise pollution for a long time possibly make its mood agitation, influence operating efficiency etc., and very the person can endanger healthy or cause the sense of hearing impaired.Especially locate in hospital etc., the air-conditioning noise is required strict more.
At present, existing muffler great majority are in common airduct, to add attractive material, like acoustical cotton; But it can increase flowing resistance, makes ventilation freely not suitable, or adopts double-deck microwell plate muffler in the place of having relatively high expectations; Volume is very big, but a lot of local installing space is limited.Therefore, in order to address the above problem, to be necessary to develop a kind of new accounting for volume be little, the noise reduction frequency range is wide, good muffling effect, windage are little, do not produce the muffler of the suitable field of purification of dirt.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention is intended to provide a kind of air-conditioning system muffler.
To achieve these goals, the technical scheme of the present invention's employing is following:
A kind of air-conditioning system muffler, said muffler is combined by 4 composite plates, and said composite plate comprises the internal layer acoustical panel, middle level acoustical panel and outer metal plates.
As a kind of preferred version, be formed with cavity between said internal layer acoustical panel and the said outer metal plates, said middle level acoustical panel is arranged in the said cavity.
As a kind of preferred version, said internal layer acoustical panel and said middle level acoustical panel are provided with micropore, and said micropore size is less than 1mm, and punching rate is 1～3%.
As a kind of preferred version, acoustical panel cross section, said middle level is sinusoidal waveform, makes said cavity be separated into several sinusoidal waveform cavitys.
As a kind of preferred version, be connected to form link slot between the said composite plate, said link slot cross section is a V-type.
As a kind of preferred version, also comprise clip, said clip is riveted in the said link slot.
In terms of existing technologies, beneficial effect of the present invention is:
1, through being set, internal layer microwell plate and middle level sinusoidal waveform microwell plate and outer field metallic plate form muffler; Effectively form the sinusoidal noise-reducing structure of complex multi-cavity; To high, in, the end frequently noise all have good erasure effect, it is narrow to have solved noise reduction frequency range in the past, the shortcoming of erasure effect difference;
2, adopt the comparable double-deck microwell plate muffler of microwell plate muffler thickness of sinusoidal structured to reduce one times, airduct is simple in structure, and assembling, easy for installation because of adopting assembly type, has solved the excessive problem of transportation volume, reduces expenses.
Description of drawings
Fig. 1 is the sectional view of structure of the present invention;
Fig. 2 is a user mode structure chart of the present invention.
The specific embodiment
To combine accompanying drawing and specific embodiment that the present invention is done further description below.Like Fig. 1, shown in Figure 2, a kind of air-conditioning system muffler of the present invention; Described muffler is combined by 4 composite plates 1, and said composite plate comprises lamina rara externa 11, middle level acoustical panel plate 12 and internal layer acoustical panel 13; Said middle level acoustical panel 12 is arranged in the cavity of said lamina rara externa 11 and 12 formation of internal layer acoustical panel, and said middle level acoustical panel 12 is provided with some micropores with internal layer noise reduction 13, as a kind of preferred; Said micropore size is less than 1mm, and its punching rate forms link slot 2 1～3% between said composite plate 1 connects; Said clip 3 is riveted in the said link slot 2; Fixing adjacent composite plate 1, said acoustical panel 12 cross sections are sinusoidal wave structure, and said cavity is separated into several sinusoidal waveform cavitys.
Open when air-conditioning system, cold or warm braw passes through through airduct, the noise of air that just produces; And outwards transmit immediately, owing to be provided with sinusoidal waveform micropore acoustical panel in the cavity that lamina rara externa and inner plating form, and cavity is separated into several cavitys; The different audio frequency gets in several cavitys; Make muffler produce resonance, change into mechanical energy then, finally realize erasure effect.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of claim of the present invention all according to the technical scheme and the design of above description.
