[0051] With the above solution, when the first channel housing is fixedly connected to the second channel housing, the first channel housing and the second channel housing can be processed and shaped separately and then assembled as a whole, which facilitates the processing of the device frame.

Furthermore, this spatial arrangement allows the second channel housing to be supported by an external load-bearing structure, improving the stability of the device frame.

[0058] Furthermore, the first mounting structure facilitates the installation and fixation of the second channel housing; and the second mounting structure facilitates the installation and fixation of the adapter housing.

This allows for separate transportation of the noise reduction device and the main body, thus simplifying the relocation of the energy storage equipment. Furthermore, connecting the frame to the outside of the main body prevents the noise reduction device from occupying internal space.

[0099] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

[0100] In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or operating state, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "comprising" means "including but not limited to". The terms first, second, third, etc., are used merely as illustrative purposes and do not impose numerical requirements or establish a numerical order.

[0101] In this application, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. A and B can be singular or plural.

[0102] According to the first aspect of this application, referring to Figures 1 to 3 This application provides a noise reduction device 100 for reducing noise in a liquid cooler 220. The noise reduction device 100 includes a device frame 110, a first noise reduction component 120, and a second noise reduction component 130.

[0103] The device frame 110 has an air inlet 110a, an air outlet 110b, a first vent 110c, and a second vent 110d. The air inlet 110a is connected to the first vent 110c, and the air outlet 110b is connected to the second vent 110d. The first vent 110c and the second vent 110d are respectively configured to be connected to the liquid chiller 220. The airflow entering through the air inlet 110a is input into the liquid chiller 220 along the first vent 110c, and the airflow output from the liquid chiller 220 is discharged along the second vent 110d and the air outlet 110b. At least a portion of the first noise reduction component 120 is disposed between the air inlet 110a and the first vent 110c, so that noise is reduced when passing through the first noise reduction component 120; at least a portion of the second noise reduction component 130 is disposed between the second vent 110d and the air outlet 110b, so that noise is reduced when passing through the second noise reduction component 130; the first noise reduction component 120 and the second noise reduction component 130 are respectively mounted to the device frame 110.

[0104] It is understood that the first vent 110c can be directly connected to the liquid chiller 220, or connected through an additional channel. The specific connection method can be selected according to design and installation requirements, and is not specifically limited. The second vent 110d can be directly connected to the liquid chiller 220, or connected through an additional channel. The specific connection method can be selected according to design and installation requirements, and is not specifically limited. The first noise reduction component 120 and the second noise reduction component 130 can be fixedly connected or movably connected to the device frame 110.

[0105] Through the above technical solution, since the noise of the liquid chiller 220 is transmitted through the air inlet 110a and the air outlet 110b, this application can reduce the noise of the liquid chiller 220 radiating to the outside along the path of the first air outlet 110c and the air inlet 110a by setting the first noise reduction component 120 between the air inlet 110a and the first ventilation port 110c; and can reduce the noise of the liquid chiller 220 radiating to the outside along the path of the second ventilation port 110d and the air outlet 110b by setting the second noise reduction component 130 between the air outlet 110b and the second ventilation port 110d; and, this application installs the first noise reduction component 120 and the second noise reduction component 130 to the same device frame 110 respectively, which facilitates the overall installation of the noise reduction device 100 and is beneficial to the maintenance of the noise reduction device 100.

[0106] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The air inlet 110a and the first ventilation opening 110c are located at different positions in the first direction.

[0107] By adopting this scheme, the air inlet 110a and the first ventilation opening 110c are set at different positions in the first direction, so that the air inlet 110a can avoid the surrounding space of the liquid cooler 220, which is beneficial to the maintenance of the liquid cooler 220 and facilitates the spatial arrangement of the air inlet 110a.

[0108] It should be noted that the first direction here refers to the up and down direction only for the convenience of introducing specific embodiments of this application. There is no absolute correspondence between the first direction and the up and down direction. Similarly, there is no absolute correspondence between the second direction and the front and back direction, and between the third direction and the left and right direction. Furthermore, the first direction, second direction, and third direction of this application are only used to express relative positional relationships. They only indicate approximate locations, not absolute geometric relationships.

[0109] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The air outlet 110b and the first ventilation opening 110c are located at different positions in the first direction.

[0110] By adopting this scheme, the air inlet 110a and the first ventilation opening 110c are set at different positions in the first direction, so that the air inlet 110a can avoid the surrounding space of the liquid cooler 220, which is beneficial to the maintenance of the liquid cooler 220 and facilitates the spatial arrangement of the air outlet 110b.

[0111] In one example of this application, the air inlet 110a and the air outlet 110b are positioned at the same height, and are located on opposite sides of the device frame 110 in the front-to-back direction. Of course, the arrangement direction of the air inlet 110a and the air outlet 110b on the device frame 110 can also be selected according to the application scenario targeted by the noise reduction device 100; for example, the air inlet 110a and the air outlet 110b can be located on adjacent sides of the device frame 110.

[0112] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The air inlet 110a and the second vent 110d are located at different positions in the second direction, which intersects with the first direction.

[0113] Specifically, the second direction is inclined to the first direction or perpendicular to it.

[0114] By adopting this scheme, the air inlet 110a and the second vent 110d are positioned at different locations in the second direction, so that the device frame 110 can be better adapted to the arrangement of the air inlet 221 and the air outlet 222 on the liquid cooler 220, thereby improving the overall compactness of the noise reduction device 100 and the liquid cooler 220. At the same time, the radiation path between the first vent 110c and the air inlet 110a can be extended. Based on this, the cooperation with the first noise reduction component 120 can improve the noise reduction effect.

[0115] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The air outlet 110b and the second vent 110d are located at different positions in the second direction, and the second direction intersects with the first direction.

[0116] By adopting this scheme, the air outlet 110b and the second vent 110d are positioned at different locations in the second direction, so that the device frame 110 can be better adapted to the arrangement of the air inlet 221 and the air outlet 222 of the liquid cooler 220, thereby improving the overall compactness of the noise reduction device 100 and the liquid cooler 220. At the same time, the radiation path between the second vent 110d and the air outlet 110b can be extended. On this basis, the cooperation with the second noise reduction component 130 can improve the noise reduction effect.

[0117] In one example of this application, reference is made to Figure 4 The air inlet 110a and the air outlet 110b are spaced apart in the front-to-back direction to avoid mutual interference of airflow near the air inlet 110a and the air outlet 110b.

[0118] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The device frame 110 also has a guide channel 110e. The guide channel 110e is located between the first noise reduction component 120 and the first vent 110c, and is used to guide the airflow entering from the air inlet 110a from the first noise reduction component 120 to the first vent 110c.

[0119] It is understood that the guide channel 110e can be a curved or inclined channel to adapt to the spatial position of the first noise reduction component 120 and the first vent 110c.

[0120] By adopting this scheme, the space arrangement of the air inlet 110a and the first ventilation opening 110c can be well adapted through the setting of the guide channel 110e, ensuring smooth airflow.

[0121] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4The device frame 110 includes an adapter housing 111. The adapter housing 111 forms an adapter window 111a and a first vent 110c; the adapter window 111a and the first vent 110c are disposed on opposite sides of the adapter housing 111, and at least a portion of the guide channel 110e is located in the adapter housing 111.

[0122] It is understood that the guide channel 110e can be formed by the adapter housing 111, or it can be an independent channel isolated from the adapter housing 111.

[0123] By adopting the above solution, the adapter window 111a is set up in conjunction with the first ventilation port 110c to provide an inspection port, which facilitates the maintenance and upkeep of the liquid cooler 220.

[0124] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The device frame 110 also includes a cover plate 112. The cover plate 112 covers the adapter window 111a; the adapter housing 111 and the cover plate 112 respectively form at least a portion of the channel wall of the guide channel 110e, and the guide channel 110e is connected to the adapter window 111a.

[0125] By adopting the above solution, with the cover plate 112 in place, when the liquid chiller 220 is working, the cover plate 112 closes the adapter window 111a, which can prevent airflow from leaking from the adapter window 111a; when the liquid chiller 220 is being maintained or serviced, the cover plate 112 can be operated to open the adapter window 111a, and the operator can perform maintenance and service operations on the liquid chiller 220 through the adapter window 111a and the first vent 110c.

[0126] In some specific embodiments, the cover plate 112 is detachably connected to the adapter housing 111, for example, by screw connection; or, the cover plate 112 can also be movably connected to the adapter housing 111, for example, by rotational connection or sliding connection; the connection method between the cover plate 112 and the adapter housing 111 can be selected according to design requirements.

[0127] In some specific implementation methods, refer to Figure 1 and Figure 4 A handle 112a is also provided on the side of the cover plate 112 away from the first vent 110c for easy operation.

[0128] In some embodiments of this application, the first noise reduction component 120 and the second noise reduction component 130 may employ sound-absorbing blades, which achieve noise reduction by blocking the propagation of sound waves. Of course, the first noise reduction component 120 and the second noise reduction component 130 may also use sound-absorbing cotton, resistive silencers, etc., instead of sound-absorbing blades or in combination with sound-absorbing blades.

[0129] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The first noise reduction component 120 includes: a first sound-absorbing blade 121.

[0130] At least two first silencing blades 121 are spaced apart along a first direction; each first silencing blade 121 includes a first guide surface 121a and a second guide surface 121b respectively disposed on both sides of a predetermined reference surface Q; the predetermined reference surface Q is inclined relative to the first direction, and the first guide surface 121a and the second guide surface 121b are respectively configured as arc-shaped surfaces.

[0131] It can be understood that in two adjacent first silencer blades 121, a first channel for airflow is formed between the first guide surface 121a and the second guide surface 121b, which are arranged opposite to each other.

[0132] It should be noted that the predetermined reference plane Q is a virtual plane, and different first noise-absorbing blades 121 are arranged with the first guide surface 121a and the second guide surface 121b based on different predetermined reference planes Q.

[0133] By adopting the above scheme, the first guide surface 121a and the second guide surface 121b are set to guide the airflow to ensure the ventilation function. At the same time, by limiting the predetermined reference surface Q to be inclined relative to the first direction, and by setting the first guide surface 121a and the second guide surface 121b to be arc-shaped surfaces, sound waves can be effectively reflected, thereby reducing the sound pressure level of noise.

[0134] In some specific embodiments, the first silencing blade 121 is made of porous sound-absorbing material. Through the combined effect of the reflection of the first silencing blade 121 and the absorption of the porous sound-absorbing material, the sound wave energy is weakened, and the sound pressure level of the noise is further reduced.

[0135] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The second noise reduction component 130 further includes: a second silencer blade 131. At least two second silencer blades 131 are spaced apart along a second direction; the second silencer blades 131 extend from the second vent 110d to the air outlet 110b; the second direction intersects with the first direction.

[0136] It is understandable that a second channel for airflow is formed between two adjacent second silencer blades 131.

[0137] By adopting the above scheme, the second silencing blade 131 extends from the second vent 110d to the air outlet 110b, and continuous silencing treatment can be carried out on the airflow path from the second vent 110d to the air outlet 110b, thereby reducing the sound pressure level of the noise.

[0138] In some specific embodiments, the second silencing blade 131 is made of porous sound-absorbing material. Through the combined effect of the reflection of the second silencing blade 131 and the absorption of the porous sound-absorbing material, the sound wave energy is weakened, and the sound pressure level of the noise is further reduced.

[0139] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The device frame 110 has a flow guide 115. The flow guide 115 extends from the second vent 110d to the air outlet 110b; the flow guide 115 is arc-shaped, and at least two second silencer blades 131 are installed on the flow guide 115.

[0140] By adopting the above solution, and through the arrangement of the guide section 115, and by installing the second silencer blade 131 onto the guide section 115, the guide section 115 can provide stable support for the second silencer blade 131. At the same time, by setting the guide section 115 to an arc shape, airflow resistance can be reduced.

[0141] In some embodiments of this application, reference is made to Figure 1 and Figure 4 The device frame 110 includes: a first channel housing 113 and a second channel housing 114.

[0142] The first channel housing 113 forms an air inlet 110a and a first ventilation opening 110c, and at least a portion of the first noise reduction component 120 is disposed within the first channel housing 113; the second channel housing 114 forms an air outlet 110b and a second ventilation opening 110d, and at least a portion of the second noise reduction component 130 is disposed within the second channel housing 114.

[0143] By adopting the above scheme, the first channel housing 113 and the second channel housing 114 are set to realize the air intake function and the air outlet function respectively, thereby facilitating the assembly of the first noise reduction component 120 and the second noise reduction component 130.

[0144] In some embodiments of this application, the first channel housing 113 is fixedly connected to the second channel housing 114.

[0145] Specifically, the first channel housing 113 and the second channel housing 114 can be fixedly connected into a whole by means of bolts, welding or other methods.

[0146] Using the above scheme, the first channel housing 113 and the second channel housing 114 can be processed and formed separately and then assembled as a whole, which facilitates the processing of the device frame 110.

[0147] In some embodiments of this application, the first channel housing 113 and the second channel housing 114 are integrally formed, thereby improving the forming efficiency and structural strength of the device frame.

[0148] In some embodiments of this application, the first channel housing 113, the second channel housing 114, and the adapter housing 111 can be integrally formed.

[0149] In one example of this application, a portion of the guide channel 110e is formed directly in the adapter housing 111, and another portion is formed in the first channel housing 113.

[0150] In some embodiments of this application, reference is made to Figures 1 to 3 The adapter housing 111 is perpendicular to the whole formed by the first channel housing 113 and the second channel housing 114.

[0151] It is understood that the adapter housing 111 is located at the bottom of the whole formed by the first channel housing 113 and the second channel housing 114.

[0152] By employing this design, and by defining the adapter housing 111 as perpendicular to the entire structure formed by the first channel housing 113 and the second channel housing 114, the first channel housing 113 and the second channel housing 114 can be prevented from obstructing the liquid cooler 220 in the first direction. Simultaneously, it facilitates the air intake of the air inlet 110a and the air outlet 110b. Furthermore, this spatial arrangement allows the second channel housing 114 to be stably supported by the external load-bearing structure, improving the stability of the device frame 110.

[0153] In some embodiments of this application, the second channel housing 114 is provided with a first mounting structure for connection to an external support structure. The first mounting structure facilitates the installation and fixation of the second channel housing 114.

[0154] In some embodiments of this application, the adapter housing 111 is provided with a second mounting structure for connection to an external support structure. The second mounting structure facilitates the installation and fixation of the adapter housing 111.

[0155] It should be noted that only one of the first mounting structure and the second mounting structure can be provided on the device frame to improve the flexibility of the device frame 110; or, both the first mounting structure and the second mounting structure can be provided to improve the installation stability of the device frame 110 on the external load-bearing structure.

[0156] In some specific implementations, the first mounting structure can be at least one of a flange structure, a bolt hole, a pin hole snap-fit ​​structure, etc. The second mounting structure can be at least one of a flange structure, a bolt hole, a pin hole snap-fit ​​structure, etc.

[0157] In some embodiments of this application, reference is made to Figure 2 , Figure 4 and Figure 6 The device frame 110 also includes a support member 160.

[0158] The carrier 160 has a forklift hole 160a communicating with the outside; the carrier 160 is fixedly connected to the device frame 110; in a first direction, at least a portion of the carrier 160 is located between the air inlet 110a and the first vent 110c.

[0159] By adopting the above solution, the carrier with a forklift hole 160a is provided to facilitate the transportation and installation of the noise reduction device 100. Furthermore, the carrier 160 is positioned between the air inlet 110a and the first ventilation opening 110c, that is, the position where the noise reduction device 100 cooperates with the forklift is in the middle of the device frame 110, thereby improving the stability of the noise reduction device 100 during transportation and installation.

[0160] In some embodiments of this application, reference is made to Figure 2 , Figure 4 and Figure 6 At least a portion of the support member 160 is located inside the device frame 110.

[0161] By adopting the above solution, at least a portion of the support member 160 is located inside the device frame 110, thus avoiding the need for the support member to increase the volume of the device frame.

[0162] It should be noted that the forklift hole 160a is isolated from the guide channel 110e; and the size of the carrier 160 is smaller than the size of the guide channel 110e. Therefore, even if part of the carrier 160 is located in the guide channel 110e, it will not affect the airflow transmission in the guide channel 110e.

[0163] In one example of this application, reference is made to Figure 2 Two carriers 160 are spaced apart in the third direction (left and right direction), and the carriers 160 are fixedly connected to the adapter housing 111 and are at least partially inserted into the adapter housing 111.

[0164] In some embodiments of this application, the noise reduction device 100 further includes a sealing plate 140, which covers the forklift hole 160a and can close the forklift hole 160a when it is not in use.

[0165] In some embodiments of this application, reference is made to Figure 1 The noise reduction device 100 also includes multiple lifting rings 150, which are fixedly connected to the top of the device frame 110 to facilitate the hoisting of the noise reduction device 100.

[0166] According to the second aspect of this application, referring to Figures 7 to 9 This application provides an energy storage device 10, including a device body 210, a liquid chiller 220, and a noise reduction device 100 as described above; at least a portion of the liquid chiller 220 is located in the device body 210, the noise reduction device 100 is installed in the device body 210, a first vent 110c is connected to the air inlet 221 of the liquid chiller 220, and a second vent 110d is connected to the air outlet 222 of the liquid chiller 220.

[0167] The energy storage device 10 has all the beneficial effects of the noise reduction device 100 described above, which will not be repeated here.

[0168] It should be noted that the above-mentioned external load-bearing structure can be the container itself or an external structure installed on the container.

[0169] In one example of this application, the energy storage device 10 in this embodiment can be an energy storage container, and the device body 210 is equipped with devices such as a battery pack, a battery management system, and an energy conversion system.

[0170] In some specific implementation methods, refer to Figures 8 to 10 The adapter housing 111 is located on the front side of the liquid cooler 220, and the side of the liquid cooler 220 with a larger area is positioned opposite to the first adapter housing 111.

[0171] In some embodiments of this application, reference is made to Figure 9 At least a portion of the device frame 110 is mounted on top of the device body 210, with the device body 210 providing support for the device frame 110. More specifically, the second channel housing 114 is located on top of the device body 210, while the adapter housing 111 rests against the front side of the device body 210.

[0172] In some embodiments of this application, reference is made to Figures 8 to 10 The device frame 110 is detachably connected to the outside of the device body 210.

[0173] Using the above-described solution, the device frame 110 is detachably connected to the device body 210, facilitating the separation and installation of the noise reduction device 100 from the device body 210. This allows the noise reduction device 100 and the device body 210 to be transported separately, thus facilitating the transfer of the energy storage device 10. Simultaneously, by connecting the device frame 110 to the outside of the device body 210, the noise reduction device 100 does not occupy the internal space of the device body 210.

[0174] Specifically, the device frame 110 can be connected to the equipment body 210 by means of bolt connection, pin connection and snap-fit.

[0175] In some embodiments of this application, reference is made to Figure 10 and Figure 11 The energy storage device 10 also includes a first protective net 230. The first protective net 230 is located between the first vent 110c and the air inlet 221 of the liquid chiller 220. By setting the first protective net 230, external impurities can be reduced from entering the liquid chiller 220 through the first vent 110c, thus ensuring the working life of the liquid chiller 220.

[0176] In some specific embodiments, the first protective net 230 may be installed on at least one of the equipment body 210, the liquid cooler 220, or the device frame 110.

[0177] In some embodiments of this application, reference is made to Figure 10 and Figure 11 The energy storage device 10 also includes a second protective net 240. The second protective net 240 is located between the second vent 110d and the exhaust vent 222 of the liquid chiller 220. By setting the second protective net 240, external impurities can be reduced from entering the liquid chiller 220 through the second vent 110d, thus ensuring the working life of the liquid chiller 220.

[0178] In some specific embodiments, the second protective net 240 may be installed on at least one of the equipment body 210, the liquid cooler 220, or the device frame 110.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
