Embodiment
Core of the present utility model is to provide a kind of muffler assembly, has the noise that equipment when operation of blower fan produces to reduce.Another core of the present utility model is to provide a kind of fan coil unit that comprises above-mentioned muffler assembly.
In order to make those skilled in the art understand better the technological scheme that the utility model provides, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-4, the muffler assembly that the utility model embodiment provides is applied in the equipment with blower fan, and the gas in object space will enter this equipment under the effect of blower fan, in gas flow process, will produce noise.The acoustical panel 12 that above-mentioned muffler assembly comprises positioning plate 11 and fixes with this positioning plate 11; Positioning plate 11 is for realizing the location of acoustical panel 12, and it can be the shell of equipment, can be also and the relatively-stationary plate of shell of equipment, and this positioning plate 11 generally extends along airflow direction, in order to avoid gas cannot pass through; On acoustical panel 12, have the noise reduction face extending along airflow direction, have gear line on this noise reduction face, this gear line is in tilted layout with respect to airflow direction.Particularly, acoustical panel 12 can be flat board, and its entirety is in tilted layout with respect to airflow direction, and now in acoustical panel 12, the one side relative with the intake grill of equipment is noise reduction face, and this noise reduction face entirety is gear line.The quantity of above-mentioned acoustical panel 12 can be one, now can adjust flexibly the arranged direction of acoustical panel 12, makes the noise reduction face area on acoustical panel 12 larger.
During above-mentioned muffler assembly work, when gas flows along airflow direction, will contact with noise reduction face, and then act on mutually with the gear line on noise reduction face, this gear line can reflect and reflect noise, then stops that noise directly spreads out of along airflow direction.Visible, than the content of introducing in background technique, the noise that above-mentioned muffler assembly produces in the time of can reducing the equipment operation with blower fan.
Further, in technological scheme, quieter material layer 13 can be set on the surface of acoustical panel 12, this quieter material layer 13 can only be arranged on a surface of acoustical panel 12, and its Pasting is on the surface of acoustical panel 12.When acoustical panel 12 is flat board, above-mentioned quieter material layer 13 is preferably disposed on the noise reduction face of acoustical panel 12.Above-mentioned quieter material layer 13 specifically can be acoustical cotton, its partial noise in can absorption equipment, the noise producing during with this reduction equipment operation to a greater degree.Certainly, the material that quieter material layer 13 also can have silencing function by other is made.
In order to strengthen the sound-absorbing effect of quieter material layer 13, the utility model embodiment all arranges quieter material layer 13 on relative two surfaces on acoustical panel 12.Obviously, the active area of quieter material layer 13 increases to some extent, and its noisiness that can absorb increases thereupon.
The noise producing during in view of the operation of some equipment is larger, only arrange technique effect that an acoustical panel 12 produces relatively a little less than, therefore the utility model embodiment is set to acoustical panel 12 multiple, multiple acoustical panels 12 form silencers channel.When the quantity of acoustical panel 12 increases, just mean that the gross area of noise reduction face increases.Now, gas flow will be by above-mentioned silencers channel when this muffler assembly, will have more gas and act on mutually with acoustical panel 12, and then absorb more noise.The distribution of above-mentioned multiple acoustical panel 12 can be determined flexibly, if the silencers channel that assurance gas can form through multiple acoustical panels 12, and then other parts of access arrangement.
Further in technological scheme, in above-mentioned multiple acoustical panels 12, the spacing between every adjacent two acoustical panels 12 equates, this spacing refers to the distance between the central point of adjacent two acoustical panels 12.This kind of set-up mode is not only conducive to the processing of muffler assembly, can also improve the performance muffler of muffler assembly, reduces the flow losses of gas simultaneously.
In embodiment, the shape of acoustical panel 12 can be multiple, such as man type etc., and the shape of acoustical panel 12 also can be irregular.For the ease of processing, absorb more noise simultaneously, the acoustical panel 12 that the utility model embodiment provides is preferably waveform acoustical panel, and reflecting effect and the refraction effect of this waveform acoustical panel to noise is stronger.The folding shape angle of above-mentioned waveform acoustical panel and folding shape number arrange flexibly according to concrete applicable situation.
In addition, above-mentioned positioning plate 11 can be two, and two positioning plates 11 are oppositely arranged, and acoustical panel 12 is fixed between two positioning plates 11, to improve the positioning precision of acoustical panel 12.
The fan coil unit that the utility model embodiment provides comprises shell and is arranged at power section, exhausting part, heat exchanging part, muffler assembly 51 and the auxiliary spare part in shell, wherein: shell comprises upper cover plate assembly 21, opening panel assembly 22, left sideboard assembly 23, base plate 24 and right sideboard assembly 25; Power section comprises motor fixing plate 41 and motor 45; Exhausting part comprises front volute 42, centrifugation blade 43, rear volute 44, support 46 and centrifugal blower parts 47; Auxiliary spare part comprises chute 52.The both sides of shell have respectively intake grill and exhaust outlet, in shell, there is air intake passage and air-out passage, gas passes through air intake passage, muffler assembly 51, exhausting part, heat exchanging part and air-out passage successively after being entered by intake grill, then by exhaust outlet, flow out this fan coil unit.Particularly, above-mentioned muffler assembly 51 can be arranged at any position in the space of gas flow warp.
Because above-mentioned muffler assembly 51 has above-mentioned technique effect, the fan coil unit with this muffler assembly 51 also should have corresponding technique effect.
In preferred technological scheme, above-mentioned muffler assembly 51 is arranged in air intake passage.The noise at air intake passage place is slightly large, therefore muffler assembly 51 is positioned over to the noise while being more conducive to the operation of reduction equipment in air intake passage.
In addition, because the shell of fan coil unit is generally hexahedron structure, therefore for the convenient muffler assembly 51 of arranging, can be by multiple acoustical panels 12 longitudinally the arranging along air intake passage in muffler assembly 51.Certainly, also can be by above-mentioned multiple acoustical panels 12 laterally arranging along air intake passage.Above-mentioned vertical and horizontal refer to respectively length direction and the width direction of the cross section of shell.
In the case of other structures of fan coil unit and configure constant, respectively above-mentioned fan coil unit not being arranged to muffler assembly 51 tests with the situation that muffler assembly 51 is set, wherein, as shown in Table 1, noise data when muffler assembly 51 is set in fan coil unit as shown in Table 2 for noise data when muffler assembly 51 is not set in fan coil unit.
