The noise that air condition compressor produces is after compressor body and connecting pipeline, the noise of medium-high frequency is many easily to be slowed down, remaining is mainly low frequency exhaust noise, secondary is intermediate frequency exhaust noise, low frequency and part intermediate frequency exhaust noise are passed to indoor by coolant media, and the use sense affecting user is subject to.
The noise reduction means of current use increases silencing apparatus exactly in air conditioner piping system, and wherein single expansion tube silencing apparatus is the simplest and easy and makees general silencing apparatus, but the noise reduction of this silencing apparatus is not very desirable.Technical problem to be solved by this invention is by the basis of existing silencing apparatus, the structure of baffler is done corresponding improvement, improves the noise reduction of silencing apparatus.
The baffler 100 according to the embodiment of the present invention is described in detail below in conjunction with Fig. 1 to Fig. 4.
According to the baffler 100 of the embodiment of the present invention, comprise housing 1, housing 1 is provided with import 101 and outlet 102, import 101 is connected with compressor by connecting pipeline, the noise that compressor produces is after compressor body and connecting pipeline, and medium-high frequency noise is wherein many easily to be alleviated, and remaining is mainly low frequency exhaust noise, secondary is intermediate frequency exhaust noise, and the baffler 100 in the embodiment of the present invention can eliminate medium and low frequency noise.
As depicted in figs. 1 and 2, a part for the perisporium of housing 1 inwardly concaves the reentrant part 111 limiting multiple annular, and multiple reentrant part 111 is spaced apart on the length direction of housing 1.
Thus, by a part of indent of the perisporium by housing 1 to limit multiple reentrant part 111, increase the number of times of noise in the reflective surface area of housing 1 inwall and reflection superposition.The compressor noise of intermediate frequency and low-frequency range, after the multiple reflections superposition of inwall, reach the effect of elimination, utilize resistive muffler principle simultaneously, when sound wave enters baffler 100, friction in the groove of part acoustic energy between adjacent reentrant part 111 and change into thermal energy consumption and dissipate, makes to be weakened by the sound wave of baffler 100.
Be understandable that, the shape of the reentrant part 111 of the baffler 100 of the embodiment of the present invention does not do concrete restriction, as long as ensure that reentrant part 111 can increase noise at the reflective surface area of housing 1 inwall and the number of times reflecting superposition.Alternatively, the cross-section area of each reentrant part 111 can form square structure.
According to the baffler 100 of the embodiment of the present invention, by a part of indent of the perisporium by housing 1 to limit multiple reentrant part 111, increase the number of times that noise superposes in the reflective surface area of housing 1 inwall and reflection, and then the noise making compressor produce is cut down to a certain extent after by baffler 100, alleviate the noise transmission of compressor operation generation to indoor phenomenon, the use sense improving user is subject to.
Preferably, as depicted in figs. 1 and 2, multiple reentrant part 111 uniform intervals distribution on the length direction of housing 1.Thus be convenient to the machine shaping of baffler 100, and improve the cosmetic look of baffler 100.
According to some embodiments of the present invention, as depicted in figs. 1 and 2, the shape of multiple reentrant part 111 is identical.Thus, make baffler 100 structure simple, easy processing, and then the manufacturing efficiency that improve baffler 100.
In some embodiments of the invention, the span of the width M on the length direction of housing 1 of each reentrant part 111 is 4mm-6mm.
Preferably, the width of each reentrant part 111 on the length direction of housing 1 is 4mm.
In some embodiments of the invention, housing 1 can comprise: the body 11 of hollow, inlet tube 2 and outer pipe 3.
Wherein, as shown in Figure 2, a part for the perisporium of body 11 inwardly concaves to limit multiple reentrant part 111.Reentrant part 111 increases the number of times that noise superposes in the reflective surface area of housing 1 inwall and reflection.
Inlet tube 2 and outer pipe 3 are located in the opposing sidewalls of body 11, and the free end of inlet tube 2 limits import 101, and the free end of outer pipe 3 limits outlet 102.
One end of body 11 is inlet tube 2, and the other end of body 11 is outer pipe 3, and body 11 internal structure is hollow structure, and the refrigerant of discharging from compressor enters into body 11 by inlet tube 2, is then discharged by outer pipe 3.Wherein, body 11, inlet tube 2 and outer pipe 3 can be formed in one part, can also be independently be processed into shaped piece.
Further, the cross-section area of the first pontes 12 be connected with inlet tube 2 of body 11 is increasing to the direction of outer pipe 3 gradually from inlet tube 2, and the cross-section area of second attachment portion 13 be connected with outer pipe 3 of body 11 is reducing to the direction of outer pipe 3 gradually from inlet tube 2.
That is, the diameter of inlet tube 2 and outer pipe 3 is less than the diameter in the middle part of body 11, and a part (that is, the first pontes 12 and the second attachment portion 13) diameter on body 11 needs to reduce gradually to be connected with outer pipe 3 with inlet tube 2.Thus be convenient to the machine shaping of housing 1.
Further, the perisporium of the first pontes 12 and the angle of horizontal plane are 40 ° ~ 55 °, and the perisporium of the second attachment portion 13 and the angle of horizontal plane are 40 ° ~ 55 °.
Preferably, the perisporium of the first pontes 12 and the angle of horizontal plane are 45 °, and the perisporium of the second attachment portion 13 and the angle of horizontal plane are 45 °.Thus, make silencing apparatus 100 processing technology simple, improve the manufacturing efficiency of silencing apparatus 100.
In some embodiments of the invention, the span of the ratio of the degree of depth N diametrically of each reentrant part 111 and the diameter of body 11 is: 1:8 to 1:12.
In examples more of the present invention, the inner circle wall of inlet tube 2 is provided with the first spacing preiection 21, and the inner circle wall of outer pipe 3 is provided with the second spacing preiection 31.
Thus, connecting pipeline is being inserted into after in inlet tube 2 and outer pipe 3, first spacing preiection 21 and the second spacing preiection 31 can play position-limiting action, thus by being provided with the first spacing preiection 21 and the second spacing preiection 31, may be used for depth localization when connecting pipeline is inserted into baffler.
Preferably, import 101 and outlet 102 are arranged with one heart.
Thus, make the structure of baffler 100 simple, easy processing, and then the manufacturing efficiency that improve baffler 100.
Certainly, be understandable that, import 101 and outlet 102 also can non-concentric be arranged, and to increase the order of reflection of sound in body 11 inside, improve soundproof effect further.
There is provided one below according to the preferred embodiment of silencing apparatus 100 of the present invention.
According to the circular pipe that the inlet tube 2 of the silencing apparatus 100 of the embodiment of the present invention is internal diameter 9.52mm, on the inwall of inlet tube 2, distance inlet tube 2 port 9mm place is provided with the first spacing preiection 21, and on the inwall of outer pipe 3, distance outer pipe 3 port 9mm place is provided with the second spacing preiection 31.First spacing preiection 21 and the second spacing preiection 31 are for depth localization during connecting pipeline reeve baffler; The length of inlet tube 2 and outer pipe 3 is 12mm.
The perisporium of the first pontes 12 is with horizontal plane angle at 45 ° and be connected with body 11, and the perisporium of the second attachment portion 13 is with horizontal plane angle at 45 ° and be connected with body 11, and body 11 diameter is 19mm, and length is 37mm; A part for body 11 inwardly concaves the reentrant part 111 forming multiple annular, width M desirable 4mm, 5mm, 6mm of each reentrant part 111, and the degree of depth N of reentrant part 111 is 2mm, and the number of reentrant part 111 should be greater than 2; The internal diameter of outlet 103 is 9.52mm, and the total length of baffler is 70mm; The baffler of this structure is mounted on the outlet pipe of air conditioner outdoor machine.
