Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure generally relate to the field of sound absorption devices, and more particularly to a muffler, a cooling system, a motor system, and a generator system. Background Art
[0002] In the design and implementation of electronic or mechanical equipment (such as an air cooler or an air-to-air cooler), the control of noise emissions is usually important. Known muffler structures for such coolers used in motors and generators have a simple structure, but the ability to absorb noise cannot meet the high requirements of customers for sound pressure levels, such as 85 or 80 dB(A).
[0003] Therefore, a new method for improving the ability to absorb noise is needed. Summary of the Invention
[0004] In view of the foregoing problems, various exemplary embodiments of the present disclosure provide a muffler for improving the ability to absorb noise, and also provide a cooling system including the muffler, a motor system including the muffler, and a generator system including the muffler.
[0005] In a first aspect of the present disclosure, exemplary embodiments of the present disclosure provide a muffler. The muffler includes: a housing and a guiding portion. The housing includes: an inner wall provided with a damping material; an inlet disposed at a first portion of the housing and adapted to receive air from an air outlet of a cooler; a first outlet disposed at a second portion of the housing and configured to discharge air flowing through a first air flow channel, the second portion being adjacent to the first portion; and a second outlet disposed at a third portion of the housing and configured to discharge air flowing through a second air flow channel, the third portion being adjacent to the first portion; and a guiding portion disposed at a fourth portion of the housing opposite to the inlet and configured to guide the received air to the first outlet and the second outlet along the first air flow channel and the second air flow channel respectively.
[0006] With this arrangement, the air entering the muffler is guided to the outlets through two separate air flow channels. In this way, more noise is absorbed within the housing and a lower sound level is achieved.
[0007] In some embodiments, the second portion is opposite to the third portion.
[0008] With this arrangement, the air entering the muffler is discharged through two separate paths. Compared with known solutions, the noise is not concentrated at one outlet. In this way, more noise is absorbed and a lower sound level is achieved.
[0009] In some embodiments, the guiding portion extends from the fourth part of the housing towards the inlet in a dimensionally reduced manner.
[0010] With this arrangement, the gradient surface shape of the guiding portion will help to guide the air flow to the first outlet and the second outlet. In this way, the potential noise generated by the eddy air flow in the housing will be reduced or eliminated.
[0011] In some embodiments, the guiding portion includes a first curved surface and a second curved surface opposite to the first curved surface to respectively guide the air to flow towards the first outlet and the second outlet.
[0012] With this arrangement, the first curved surface and the second curved surface help to reduce the resistance of the air flowing in the first air flow channel and the second air flow channel, thereby reducing the noise generated on the surface of the guiding portion.
[0013] In some embodiments, the cross-section of the guiding portion has a shape of any one of the following: Y-shaped, triangular, semi-circular, and elliptical.
[0014] With this arrangement, the surface of the guiding portion will help to reduce the resistance of the air flowing in the first air flow channel and the second air flow channel, thereby reducing the noise generated on the surface of the guiding portion.
[0015] In some embodiments, the first curved surface and the second curved surface are provided with damping materials.
[0016] With this arrangement, the damping materials will absorb more noise.
[0017] In some embodiments, the muffler further includes: a first fence disposed at the first outlet and including at least one first rod extending from a first edge of the first outlet to a second edge of the first outlet opposite to the first edge; and a second fence disposed at the second outlet and including at least one second rod extending from a first edge of the second outlet to a second edge of the second outlet opposite to the first edge of the second outlet; wherein, the surfaces of the first fence and the second fence in the housing are provided with damping materials.
[0018] With this arrangement, the first fence and the second fence will reflect the sound back into the inner wall of the housing, so that the reflected sound is further absorbed by the damping materials, thereby further reducing the noise.
[0019] In some embodiments, the inner walls of the guiding portions respectively include circular corners at the joints between the guiding portions and the inner walls of the housing. With this arrangement, the air flowing to the joints will be smoothly guided, thereby avoiding or reducing the generation of noise here. Specifically, the circular corners of the air path result in lower air flow losses, less corner noise generation, and ultimately better sound level and temperature rise performance. The better temperature rise performance can lead to the use of less core component material, thus saving costs.
[0020] In some embodiments, the total area of the first outlet and the second outlet is greater than the area of the air outlet of the cooler.
[0021] With this arrangement, the air from the air outlet of the cooler will be able to flow smoothly through the first outlet and the second outlet, such that the heat generated in the cooler will be quickly dissipated.
[0022] In some embodiments, the total area is in the range of 1.2 times to 1.5 times the area of the air outlet of the cooler.
[0023] With this arrangement, the heat generated in the cooler will be quickly dissipated through the outlet of the muffler, and the housing does not need to be set to have too large a volume.
[0024] In some embodiments, the housing is positioned such that the first outlet and the second outlet are in the horizontal direction under operating conditions.
[0025] With this arrangement, the air from the air outlet of the cooler will be discharged from both sides of the housing, thereby avoiding the concentration of hot air, and thus promoting the thermal balance of the cooler.
[0026] In some embodiments, a protective film is provided on the surface of the damping material. The surface of the protective film is generally smooth and has much less resistance to air.
[0027] With this arrangement, the damping material will be fixed and protected by the protective film. In addition, the smooth surface makes the air flow smoother, and the noise here will be smaller.
[0028] In a second aspect, example embodiments of the present disclosure provide a cooling system. The cooling system includes: an air cooler or an air-to-air cooler; and a muffler according to any of the mufflers of the first aspect, the muffler being coupled to the air cooler or the air-to-air cooler.
[0029] With this arrangement, more noise is absorbed in the muffler and a lower sound level is achieved, and thus a cooling system with improved noise absorption ability is obtained.
[0030] In a third aspect, example embodiments of the present disclosure provide a generator system, the generator system comprising: a generator; an air cooler or an air-to-air cooler, the air cooler or the air-to-air cooler being coupled to the generator and configured to cool the generator; and a muffler according to any one of the mufflers of the first aspect, the muffler being coupled to the air cooler or the air-to-air cooler.
[0031] With this arrangement, more noise is absorbed in the muffler and a lower sound level is achieved, and thus a generator system with improved noise absorption ability is obtained.
[0032] In a fourth aspect, example embodiments of the present disclosure provide a motor system, the motor system comprising: a motor; an air cooler or an air-to-air cooler, the air cooler or the air-to-air cooler being coupled to the motor and configured to cool the motor; and a muffler according to any one of the mufflers of the first aspect, the muffler being coupled to the air cooler or the air-to-air cooler.
[0033] With this arrangement, more noise is absorbed in the muffler and a lower sound level is achieved, and thus a motor system with improved noise absorption ability is obtained.
[0034] It should be understood that the summary section is not intended to identify key or essential features of the embodiments of the present disclosure, nor is it intended to be used to limit the scope of the present disclosure. Through the following description, other features of the present disclosure will become readily understandable. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The principles of the present disclosure will now be described with reference to several exemplary embodiments shown in the drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the description of the embodiments is only for facilitating a better understanding by those skilled in the art and thus implementing the present disclosure, rather than limiting the scope of the present disclosure in any way.

Unless the context clearly indicates otherwise, the definitions of the terms are consistent throughout the specification.
[0046] As described above, in some cases, the noise absorption ability of known mufflers for air coolers or air - air coolers cannot meet the high requirements of customers for sound pressure levels. For ease of understanding of the present invention, reference will be made to Figure 1 and Figure 2 to describe known mufflers. Figure 1 is a perspective view showing a conventional muffler together with an air - air cooler; and Figure 2 is as shown Figure 1 a cross-sectional view of the muffler.
[0047] As shown Figure 1 in, the muffler 10 is coupled to the cooler 20. The cooler 20 can be an air cooler or an air - air cooler. As is known, an air cooler has an open cycle and the cooling medium is air; while an air - air cooler has two cycle stages (a primary closed cycle, where the cooling medium is air; and a secondary open cycle, where the cooling medium is also air).
[0048] The cooler 20 can be equipped on a motor or a generator to cool the motor or the generator. As Figure 1 and Figure 2 shown, air enters the cooler 20 from the right side of the cooler 20 to cool the motor or the generator. The heated air becomes hot air, and the hot air is output from the air outlet 202 of the cooler 20. The muffler 10 is designed to reduce the noise generated by the cooler 20. The muffler 10 includes a housing 102. An outlet 104 is provided on the top of the housing 102. In other words, the outlet 104 faces upward.
[0049] As can be seen from Figure 2 it, the housing 102 is coupled to the air outlet 202 of the cooler 20. The hot air discharged from the outlet 202 will enter the housing 102 and leave from the outlet 104 of the muffler 10. When the hot air flows in the housing 102, the inner wall of the housing 102 will absorb sound waves. With this configuration, the hot air will be discharged only via one outlet (i.e., the outlet 104). The noise is concentrated from one air outlet, and thus the generated noise level is higher. Therefore, a new method for improving the noise absorption ability is needed.
[0050] The inventors recognize that, generally, the structure of the air outlet of a muffler is one of the key factors affecting the sound level. The noise absorption ability can be improved by changing the design of the air outlet of the muffler.
[0051] According to an embodiment of the present disclosure, a muffler is provided to reduce the noise generated by an air cooler or an air-to-air cooler. The muffler includes a housing and a guiding portion. The housing includes: an inner wall; an inlet; a first outlet and a second outlet. The inner wall is provided with a damping material, wherein the damping material can absorb sound waves. The inlet is arranged at a first portion of the housing, for example, arranged at one side of the housing. The inlet can receive air from the air outlet of the cooler. The first outlet is arranged at a second portion of the housing adjacent to the first portion. The first outlet can discharge the air flowing through the first air flow channel. The second outlet is arranged at a third portion of the housing adjacent to the first portion. The second outlet can discharge the air flowing through the second air flow channel. The guiding portion is arranged at a fourth portion of the housing opposite to the inlet. The guiding portion can guide the received air to the first outlet and the second outlet along the first air flow channel and the second air flow channel respectively. With this arrangement, the air entering the muffler is guided to the outlets through two separate air flow channels. In this way, more noise is absorbed inside the housing and a lower sound level is achieved.
[0052] The above idea can be implemented in various ways, as will be described in detail in the following paragraphs.
[0053] Hereinafter, reference will be made toFigures 3 to 5 Describe the principles of the present disclosure in detail. Figure 3 is a perspective view of a generator system 100 according to an embodiment of the present disclosure; Figure 4 As shown in Figure 3 a front view of the generator system 100; and Figure 5 As shown in Figure 3 a left view of the generator system 100.
[0054] In some embodiments, as shown in Figure 3 the generator system 100 includes a generator 60 and a cooling system. The cooling system is disposed on top of the generator 60. The cooling system includes a cooler 40, an air input device 50 coupled to a first side of the cooler 40, and a muffler 30 coupled to a second side of the cooler 40. The cooler 40 may be an air cooler or an air - air cooler.
[0055] In some embodiments, a plurality of pipes are disposed in the cooler 40. Air is input from the air input device 50 into the cooler 40. Specifically, the air entering the cooler 40 is input into the pipes and flows through the pipes. The heat generated by the generator 60 will heat the air around it. The heated air will exchange heat with the pipes and the air inside the pipes. The air flowing in the pipes will cool the pipes and will thus be heated. The hot air will be discharged through an air outlet described in detail later. Thereafter, the hot air will enter the muffler 30.
[0056] Referring to Figures 3 to 5 , the muffler 30 includes a housing 302. The housing 302 includes: an inner wall, an inlet 319 (see Figure 7 ), a first outlet 304, and a second outlet 305. The inlet 319 is disposed at a first portion of the housing 302 and is configured to receive air from an air outlet 402 of the cooler 40. The first outlet 304 is disposed at a second portion of the housing 302 and is configured to discharge a portion of the air entering the housing 302, the second portion being adjacent to the first portion. The second outlet 305 is disposed at a third portion of the housing 302 and is configured to discharge another portion of the air entering the housing 302, the third portion being adjacent to the first portion.
[0057] The muffler 30 will be described in further detail below with reference to Figures 6 to 7 . Figure 6 is a perspective view of the cooling system as shown in Figure 3 ; and Figure 7 is a cross - sectional view of the cooling system as shown in Figure 6 .
[0058] As shown in Figure 6 and Figure 7As shown, the silencer 30 is coupled to the cooler 40. Specifically, the inlet 319 of the silencer 30 is connected to the outlet 402 of the cooler 40. The housing 302 of the silencer 30 can be formed of a metallic material (such as iron, aluminum, etc.). The scope of the present disclosure is not intended to be limited to this aspect.
[0059] As Figure 6 and Figure 7 shown, the inner wall is provided with a damping material 308, which is good at absorbing sound waves. The damping material 308 can be a porous sound-absorbing material, such as sound-absorbing cotton.
[0060] In some embodiments, as Figure 6 and Figure 7 shown, the first outlet 304 is arranged at the second part of the housing 302, and the second part is adjacent to the first part. The second outlet 305 is arranged at the third part of the housing 302, and the third part is adjacent to the first part. For the silencer 30 shown in Figure 6 and Figure 7 figures, the inlet 319 is arranged on the first side of the housing 302, the first outlet 304 is arranged on the second side of the housing 302 adjacent to the first side, and the second outlet 305 is arranged on the third side of the housing 302 adjacent to the first side.
[0061] It should be understood that the housing 302 is not limited to the shape described above, but can be any other shape according to its actual requirements and working space. The scope of the present disclosure is not intended to be limited to this aspect.
[0062] In some embodiments, as Figure 6 and Figure 7 shown, the housing 302 further includes a guiding portion 320. The guiding portion 320 is arranged at the fourth part of the housing 302 opposite to the inlet 319. The guiding portion 320 can be configured to separate the space enclosed by the housing 302, so that a first air flow channel 316 and a second air flow channel 318 are formed in the space. The guiding portion 320 can guide the received air to the first outlet 304 and the second outlet 305 along the first air flow channel 316 and the second air flow channel 318 respectively. The first outlet 304 is configured to discharge the air flowing through the first air flow channel 316. The second outlet 305 is configured to discharge the air flowing through the second air flow channel 318.
[0063] In some embodiments, the guiding portion 320 extends from the fourth part of the housing 302 towards the inlet 319 in a size-reducing manner. In other words, the size of the guiding portion 320 gradually decreases from the fourth part of the housing 302 to the inlet 309. As Figure 7As shown, the guiding portion 320 extends from one side of the housing 302 towards the inlet 319. The end of the guiding portion 320 can extend to a position at a predetermined distance from the inlet 319. The range of the predetermined distance can be, for example, one-tenth to one-half of the distance from one side of the housing 302 to the inlet 319. The scope of the present disclosure is not intended to be limited in this regard. Other predetermined distances are possible according to actual requirements.
[0064] Theoretically, the multiple pipes in the cooler 40 are evenly distributed. In practice, the wind speed of each pipe is different, especially in the middle region opposite the inlet 319. For example Figure 1 and Figure 2 For the muffler shown, disturbances are likely to occur in the middle region, and thus there will be wind noise friction. In other words, the air hitting the middle region opposite the inlet 319 will form eddy currents, and thus noise will be generated here. Compared with the muffler 10 shown in Figure 1 and Figure 2 In the present invention, since the guiding portion 320 is arranged in the middle region opposite the inlet 319, and the size of the guiding portion 320, especially the cross-section (as shown in Figure 7 ), gradually decreases towards the inlet 319, the air entering the housing 302 will be smoothly guided to the first outlet 304 and the second outlet 305. In this case, few eddy currents are generated. In this way, the potential noise generated by the eddy current airflow in the housing 302 will be reduced.
[0065] In some embodiments, the guiding portion 320 includes a first curved surface 310 and a second curved surface 312 opposite to the first curved surface 310 to respectively guide the air to flow towards the first outlet 304 and the second outlet 305. In particular, the first curved surface 310 defines a part of the first air flow channel 316, and the second curved surface 312 defines a part of the second air flow channel 318. With this arrangement, the first curved surface 310 and the second curved surface 312 help to reduce the resistance of the air flowing in the first air flow channel 316 and the second air flow channel 318, thereby reducing the noise generated on the surface of the guiding portion 320.
[0066] As shown in Figure 6 and Figure 7As shown, the cross-sectional shape of the guiding portion 320 is similar to a Y shape. In fact, the shape shown is merely illustrative. The scope of the present disclosure is not intended to be limited in this regard. In some embodiments, the cross-section of the guiding portion 320 has the shape of any one of the following: a Y shape, a triangle, a semi-circle, an ellipse. In this way, the surface of the guiding portion 320 will help reduce the resistance of the air flowing in the first air flow channel 316 and the second air flow channel 318, thereby reducing the noise generated on the surface of the guiding portion 320 with a simple structure.
[0067] In some embodiments, the first curved surface 310 and the second curved surface 312 are provided with a damping material 308. As an example, the thickness of the damping material 308 can be in the range of 20 mm to 100 mm, preferably 50 mm to 60 mm. It should be understood that the scope of the present disclosure is not intended to be limited in this regard. With this arrangement, the damping material 308 will absorb more noise.
[0068] In some embodiments, the inner walls of the guiding portion respectively include circular corners 315 at the joints between the guiding portion 320 and the inner wall of the housing 302. With this arrangement, the air flowing to the joints will be smoothly guided, thereby avoiding or reducing additional noise generated here.
[0069] As described above, the first outlet is arranged at the second part of the housing. The second outlet is arranged at the third part. In some embodiments, the second part is opposite to the third part. In this way, the air entering the muffler 30 is discharged through two separate paths. Compared with the old solutions, the two air outlets (i.e., the first outlet 304 and the second outlet 305) can disperse the noise to both sides, which is more conducive to the energy absorption of the damping material 308. In addition, the air outlets on both sides better balance the ambient temperature of the machine (such as the generator 60) and help reduce the air inlet temperature of the machine in a confined space environment. Generally, the muffler 30 and the cooler 40 are equipped in a closed working space. In this case, the hot air leaving the housing 302 will flow along two paths, so the hot air will easily flow evenly in the enclosed space. In this way, more noise is absorbed and a lower sound level is achieved.
[0070] In some embodiments, the silencer 30 may further include: a first fence 306 disposed at the first outlet 304 and including at least one first rod extending from a first edge of the first outlet 304 to a second edge of the first outlet 304 opposite the first edge; and a second fence 307 disposed at the second outlet 305 and including at least one second rod extending from a first edge of the second outlet 305 to a second edge of the second outlet 305 opposite the first edge of the second outlet 305. The surfaces of the first fence 306 and the second fence 307 in the housing 302 are provided with damping material 308. With this arrangement, the first fence 306 and the second fence 307 can increase the reflection of sound waves, thus absorbing more noise. Specifically, the first fence 306 and the second fence 307 can reflect the sound waves back into the housing 302, so that the reflected sound waves are further absorbed by the damping material 308 on the inner wall of the housing 302, thereby further reducing the noise.
[0071] As Figure 7 shown, each of the first fence 306 and the second fence 307 includes a support portion 322, and both sides of the support portion are damping material 308. The support portion 322 may be made of the same material as the material of the housing 302. The scope of the present disclosure is not intended to be limited in this regard.
[0072] As Figure 6 and Figure 7 shown, only one first rod and one second rod are shown. It should be understood that in other embodiments, according to actual requirements, the number of the first rod and the second rod may be more than two.
[0073] In some embodiments, the wind speed at some points near the first outlet 304 or the second outlet 305 may be measured. The experimental results show that the wind speeds at these points are basically the same. This indicates that the size design of the structure is reasonable.
[0074] As Figure 6 and Figure 7 shown, the first outlet 304 and the second outlet 305 are each divided into two parts. One part is in the shape of a rectangle, and the other part is in the shape of a trapezoid. The present disclosure is not limited to this.
[0075] In some embodiments, the total area of the first outlet 304 and the second outlet 305 is greater than the area of the air outlet 402 of the cooler 40. In some embodiments, the total area is in the range of 1.2 times to 1.5 times the area of the air outlet 402 of the cooler. With this arrangement, the air from the air outlet 402 of the cooler 40 will be able to flow smoothly through the first outlet 304 and the second outlet 305, so that the heat generated in the cooler 40 will dissipate quickly, and the housing 302 does not need to be set to have too large a volume.
[0076] In some embodiments, the housing 302 is positioned such that the first outlet 304 and the second outlet 305 are in a horizontal direction under operating conditions. With this arrangement, the air from the air outlet of the cooler will be discharged from both sides of the housing 302, thus avoiding the concentration of hot air and promoting the thermal balance of the cooler 40.
[0077] In some embodiments, a protective film 324 is provided on the surface of the damping material 308. The protective film 324 can fix and protect the damping material 308. The surface of the protective film 324 is generally smooth and has much less resistance to air. The smooth surface makes the air flow smoother and the noise here will be smaller.
[0078] In a second aspect, an exemplary embodiment of the present disclosure provides a cooling system. The cooling system may include: an air cooler or an air-to-air cooler 40; and a muffler 30 as described in the above exemplary embodiments, the muffler being coupled to the air cooler or the air-to-air cooler 40. With this arrangement, more noise can be absorbed in the muffler 30 and a lower sound level can be achieved, and thus a cooling system with improved noise absorption ability is obtained.
[0079] In the above embodiments, the first outlet 304 and the second outlet 305 are shown, and the scope of the present disclosure is not intended to be limited to this aspect. In some embodiments, according to actual requirements, the muffler 30 may be provided with more than two outlets.
[0080] In some embodiments, the sound pressure can be measured at a predetermined number of points around the muffler 30. The measured sound pressure is weighted to calculate the sound pressure level.
[0081] At the same power output, compared with known solutions, the muffler 30 of the present disclosure can absorb more noise and thus can obtain a lower sound level. Experiments show that known muffler designs can reduce the sound pressure level by 4 - 6 dB(A), while the new design of the present disclosure can reduce it by about 8 - 10 dB(A). That is to say, the noise reduction effect of the solution of the present disclosure is 2 - 3 dB higher than that of known solutions.
[0082] The above embodiments are merely illustrative. The scope of the present disclosure is not intended to be limited to this aspect.
[0083] In fact, the above muffler 30 is not limited to being used in an air cooler system, but can be used in a wider range of industries. For example, the muffler 30 can be used in any industry where noise reduction is required.
[0084] The muffler 30 according to an embodiment of the present invention can improve the noise absorption ability with a simple structure.
[0085] It should be understood that the muffler 30 is not limited to the configuration described above, but may have any other configuration. The scope of the present disclosure is not intended to be limited in this regard.
[0086] In addition, the muffler or cooling system of the present disclosure may be combined with one or more additional devices for operation as needed. The scope of the present disclosure is not intended to be limited in this regard.
[0087] As Figures 3 to 5 shown, an exemplary embodiment of the present disclosure provides a generator system 100. The generator system 100 includes: a generator 60; an air cooler or an air-to-air cooler 40 that is coupled to the generator 60 and configured to cool the generator 60; and a muffler 30 according to any of the mufflers 30 described in the above exemplary embodiments, the muffler being coupled to the air cooler or the air-to-air cooler 40. With this arrangement, more noise is absorbed in the muffler and a lower sound level is achieved, and thus a generator system 100 with improved noise absorption ability is obtained.
[0088] In addition, an exemplary embodiment of the present disclosure provides a motor system. The motor system includes: a motor (not shown); an air cooler or an air-to-air cooler that is coupled to the motor and configured to cool the motor; and a muffler 30 according to any of the mufflers 30 described in the above exemplary embodiments, the muffler being coupled to the air cooler or the air-to-air cooler. With this arrangement, more noise is absorbed in the muffler and a lower sound level is achieved, and thus a motor system with improved noise absorption ability is obtained.
