FIG. 1 is a schematic airflow distribution diagram when the heat dissipating holes are symmetrical in the prior art, as shown in FIG. 1, the inventor creatively recognizes that in the prior art, although the noise volume of the mixed noise in the heat dissipating airflow can be reduced by adding a multi-cavity resonance resistance silencing structure on the heat dissipating holes 200 symmetrically arranged on the left wall and the right wall of the press bin 100 and the hole walls of the heat dissipating holes 200, the airflow with high flow rate is accumulated at the bottom of the press bin 100 and is not easy to be discharged, and the flow rate of the high-temperature airflow easy to be discharged at the top of the press bin 100 is lower, which is not beneficial to heat dissipation of a compressor in the press bin 100 in the working state, so that the heat dissipating effect of the compressor is poor; meanwhile, since the heights of the two heat dissipation holes 200 are the same, each heat dissipation hole 200 bears the functions of air inlet and air outlet at the same time, the air inlet flow and the air outlet flow collide and meet at the positions of the heat dissipation holes 200, turbulence is easy to form, the flow of the air inlet flow and the air outlet flow is unfavorable, the heat dissipation effect of the compressor is poor, turbulent noise is easy to be generated when the air inlet flow and the air outlet flow collide, and user experience is reduced.
Therefore, the invention provides a technical scheme capable of solving the problem of poor radiating effect of the radiating holes with the silencing structures in the prior art.
Fig. 2 is a schematic airflow distribution diagram of a press house according to an embodiment of the present invention, as shown in fig. 2, and referring to fig. 3 to 5, the embodiment of the present invention provides a press house including a house body 300 and a muffler 400. The bin 300 includes a bin plate 310, a bottom plate 320, and wall plates 330, the bin plate 310 being positioned on the upper side of the bottom plate 320, the wall plates 330 being provided in two and on the left and right sides of the bin plate 310 and the bottom plate 320. The silencer 400 is arranged on the wall plate 330 between the box plate 310 and the bottom plate 320, and the silencer 400 is provided with a silencing channel 410 communicated with the inner space and the outer space of the bin 300; and the muffler 400 is provided on both the wall plates 330, and the muffler passages 410 of the muffler 400 are staggered up and down on the different wall plates 330.
The muffler 400 of the present invention may be made of a sound absorbing material such that sound waves propagate in the porous sound absorbing material and are radiated by friction converting sound energy into heat energy. Alternatively, the muffler 400 of the present invention may be provided with abrupt parts or bypass resonance chambers at the cross-section of the muffler channel 410, thereby reducing the sound energy radiated outward from the muffler 400. Or the silencer 400 of the present invention is a combination of the two embodiments.
In this embodiment, the bin body 300 of the press bin is formed by enclosing the box body plate 310, the bottom plate 320 and the wall plates 330, and the silencing devices 400 are arranged on the left wall plate 330 and the right wall plate 330, and the silencing channels 410 of the two silencing devices 400 are staggered up and down, so that the high-flow-rate low-temperature air flow can be discharged out of the press bin through the silencing channel 410 positioned below, and the low-flow-rate high-temperature air flow can be discharged out of the press through the silencing channel 410 positioned above. By the arrangement, the air flows with high and low flow rates can be discharged in time, and the problem that the radiating effect of the radiating holes with the silencing structure (namely the silencing channels 410 in the invention) in the prior art is poor is solved.
Further, when the compressor is operated, high temperature air in the compressor compartment flows upwards and is discharged from the upper silencer channel 410; meanwhile, as the high-temperature air flows upwards, negative pressure is generated at the bottom of the press bin, and external air enters the press bin through the lower silencing channel 410 under the action of the atmospheric pressure outside the press bin. That is, the upper muffler channel 410 is mainly air-out, and the lower muffler channel 410 is mainly air-in, so as to form an air flow penetrating through the press cabin, so that the air flow can quickly flow through the press cabin to take away heat in the press cabin, thereby improving user experience.
When the flow cross-sectional area of the silencing channel 410 in this embodiment is set to be the same as the area of the heat dissipation hole in the prior art, the air volume discharged from the press bin in unit time is detected as follows:
when the left wall and the right wall of the press bin are symmetrically provided with heat dissipation holes, the air quantity is 5.5L/min; when the heat dissipation holes are asymmetrically arranged on the left wall and the right wall of the press bin, the air volume can reach 10.5L/min, and the air volume flowing out of the press bin is effectively improved, so that the aim of effectively dissipating heat is fulfilled.
In some embodiments of the present invention, muffler 400 and wall 330 are disposed in a one-to-one correspondence. By the arrangement, high-flow-rate air flow and low-flow-rate air flow can flow to the left side and the right side of the press bin respectively, and air flow of all spaces in the press bin is promoted. When the two silencing devices 400 are arranged on one wallboard 330, the conditions that high-flow-rate air flow and low-flow-rate air flow are toward one side of the press bin, and air on the other side is gathered together and is not easy to flow, so that heat dissipation is not facilitated, and noise volume is reduced are avoided.
Specifically, the muffler passages 410 of the muffler 400 on one of the two wall plates 330 are adjacent to the case plate 310, and the muffler passages 410 of the muffler 400 on the other wall plate are adjacent to the bottom plate 320, so that the two muffler passages 410 are disposed in a staggered manner. In use, the muffler channel 410 may be disposed at a position offset from the center of the muffler 400 in the vertical direction so that one muffler 400 is installed and the other muffler 400 is installed after being rotated 180 ° on the vertical surface at the time of installation; the silencer 400 on both sides is the same size, which is convenient for production and processing. Further, the muffler 400 may be installed at a position of a ventilation window formed on the wall plate 330, so that the muffler 400 has a noise reducing function for the press bin without changing the ventilation and heat dissipation functions of the original press bin.
In some alternative embodiments of the present invention, a heat dissipation channel communicating with the inner and outer spaces of the bin 300 is formed on the wall plate 330, and the muffler 400 is disposed in the heat dissipation channel; and the heat dissipation channels on different wall plates 330 are staggered up and down. The present embodiment provides another implementation of the two silencing channels 410 being staggered up and down so as to be suitable for different refrigeration and freezing devices.
In some embodiments of the present invention, the structure of the muffler 400 is the same on different wall plates 330 and/or the opening degree of the muffler channel 410 of different muffler 400 is the same. When the structure of the press bin is regular and bilaterally symmetrical, the silencing devices 400 with the same structure can be selected, for example, the silencing channels 410 are arranged at the central positions of the silencing devices 400 in the vertical direction, so that when one silencing device 400 is installed, the other silencing device 400 is installed after being rotated 180 degrees on the vertical surface. If the structure of the press cabin is irregular or asymmetric left and right, the silencing devices 400 can be designed to be adapted to the structure of the press cabin according to the structure of the press cabin, but the opening of the silencing channels 410 of the two silencing devices 400 should be kept the same, so that the silencing devices can be suitable for high-flow and low-flow-rate airflows to be discharged out of the press cabin in time.
In some embodiments of the present invention, the sound attenuating devices 400 on different wall panels 330 are identical in structure and each include a resistive sound attenuating structure or a resistive composite sound attenuating structure. Because the structure of the press bin in each refrigerating and freezing device is different and the noise in the press bin is different, the structure of the silencer 400 can be set to be a resistance silencing structure or an impedance composite silencing structure according to the structure of the press bin and the internal noise.
Specifically, when the structure of the muffler device 400 is set to a resistant muffler structure, as shown in fig. 4, the muffler device 400 further includes a plurality of muffler chambers 420 and a porous member 430, each muffler chamber 420 having an opening 421 toward the muffler passage 410; the porous member 430 is disposed on the sound deadening passageway 410, and the sound deadening passageway 410 communicates with the sound deadening chamber 420 through the porous member 430 and the opening 421.
In this embodiment, when the noise in the press bin passes through the silencing channel 410 of the silencing device 400, the noise contains high-frequency sound waves with higher frequency and low-frequency sound waves with lower frequency, when the noise enters the silencing cavity 420 through the holes on the porous member 430, the penetrating power of the high-frequency sound waves is weak, a part of the high-frequency sound waves is reduced, the low-frequency sound waves enter the silencing cavity 420 through the porous member 430, the propagation path of the sound waves is prolonged, the energy of the sound waves is weakened, the sound which continuously diverges outwards is reduced, so that the noise generated by the press bin is reduced, the normal air exhaust and heat dissipation in the press bin are not influenced, the good noise reduction effect is realized on the premise that the normal operation of the refrigerating and freezing device is ensured, and the noise reduction effect is good.
When the structure of the muffler 400 is set to a resistive muffler structure, the muffler 400 has a sound absorbing layer made of a sound absorbing material; the sound absorbing layer is disposed on opposite sides of the two sound attenuating devices 400. Or the muffler 400 is entirely made of a sound absorbing material. When the noise in the press bin contacts the silencing layer or passes through the silencing channel 410 of the silencing device 400, the sound wave propagates in the porous sound absorbing material, and the sound energy is converted into heat energy by friction to be emitted, so that the noise propagating along the pipeline is attenuated along with the distance, the silencing purpose is achieved, and the normal air exhaust and heat dissipation in the press bin are not influenced.
When the structure of the muffler device 400 is provided as a resistance composite muffler structure, the muffler device 400 further includes a plurality of muffler chambers 420 and a porous member 430, each muffler chamber 420 having an opening 421 toward the muffler passage 410; the porous member 430 is disposed on the sound deadening passageway 410, and the sound deadening passageway 410 communicates with the sound deadening chamber 420 through the porous member 430 and the opening 421; the muffler 400 is made of a sound absorbing material.
In this embodiment, when the noise in the press cabin passes through the silencing channel 410 of the silencing device 400, the noise includes high-frequency sound waves with higher frequency and low-frequency sound waves with lower frequency, and when the noise enters the silencing cavity 420 through the holes on the porous member 430, the penetration capability of the high-frequency sound waves is weak, a part of the high-frequency sound waves is reduced, and the propagation path of the sound waves is prolonged, the energy of the sound waves is weakened, and the sound which continuously diverges outwards is reduced in the process that the low-frequency sound waves enter the silencing cavity 420 through the porous member 430; meanwhile, when the low-frequency sound waves pass through the wall of the silencing cavity 420, the sound waves propagate in the porous sound absorbing material, and the sound energy is converted into heat energy by friction to be emitted, so that noise propagating along the pipeline is attenuated along with the distance, and the noise generated by the press bin is further reduced.
In some embodiments of the present invention, the silencing channels 410 of each silencer 400 are arranged in a string shape with vertical projection on the same vertical projection plane extending front and back at intervals, so that low-flow and high-flow airflows at the upper and lower parts in the press cabin uniformly flow out.
