[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0035] like Figures 1-15 As shown, this invention discloses a noise-reducing energy storage converter cabinet, comprising a cabinet body 1. An air-gathering channel is located in the center of the cabinet body 1, dividing the interior into left and right chambers. Shelf structures are located on both the left and right sides of the air-gathering channel within the chambers. Each shelf is used to install an energy storage converter assembly 7. Each shelf has buffer noise-reducing components at both ends to buffer the energy storage converter assembly 7, thereby reducing vibration noise during operation. A closed circulating air duct 10 is formed between the shelf structures on both sides of the air-gathering channel and the inner periphery of the cabinet body 1. A fan assembly is located at the front end of the air-gathering channel, with its outlet extending into the air-gathering channel. The rear end of the air-gathering channel is connected to the circulating air duct 10. A sound-absorbing mechanism is provided on the inner wall of the cabinet body 1.

[0036] In this embodiment, as Figure 1-5 As shown in Figures 8-11 and 14, the air converging channel is located in the middle of the interior of the cabinet 1. The air converging channel includes two fixed partitions 2 that are spaced apart on the left and right and are vertically arranged. The fixed partitions are arranged longitudinally and have gaps with the front and rear ends of the cabinet. A vertically arranged connecting plate 8 is fixed between the front ends of the two fixed partitions 2. The fan assembly includes a plurality of fans 9 that are vertically spaced apart and installed on the connecting plate 8. The air outlet of the fan 9 extends between the two fixed partitions 2.

[0037] In this embodiment, each shelf structure includes multiple first support rods 4, multiple second support rods 5, and two fixed support plates 3. The multiple first support rods 4 are fixed vertically at intervals on the fixed partition 2 located on the same side, and the first support rods 4 are arranged longitudinally. The multiple second support rods 5 are distributed vertically at intervals and the multiple first support rods 4 are distributed opposite each other, and the second support rods 5 are arranged longitudinally. The multiple second support rods 5 are close to the side of the cabinet, and the positions of the multiple second support rods 5 correspond to the positions of the multiple first support rods 4. A mounting plate 6 is provided between the corresponding first support rods 4 and second support rods 5. The top of the mounting plate 6 is used to install the energy storage converter assembly 7, and the two sides of the mounting plate 6 are provided with buffer noise reduction assemblies. The two fixed support plates 3 are close to the side of the cabinet and located on the front and rear sides of the multiple second support rods 5, and the two fixed support plates 3 are fixedly connected to the multiple second support rods 5.

[0038] In this embodiment, the buffer noise reduction component includes a mounting groove 27 formed on the side adjacent to the first support rod 4 and the second support rod 5. The mounting groove 27 extends longitudinally, and a buffer pad 28 is fixedly provided inside the mounting groove 27. Both ends of the mounting plate 6 extend into the buffer pad 28 on the first support rod 4 and the second support rod 5, respectively, and the buffer pad 28 is used to buffer the mounting plate 6 and the energy storage converter component 7.

[0039] Furthermore, such as Figure 11 As shown, the buffer pad 28 is groove-shaped, with spring grooves 29 at both the top and bottom. Several vertically extending buffer springs 30 are disposed inside the spring grooves 29, distributed along the length of the buffer pad 28. The combination of the buffer pad and buffer springs buffers the mounting plate and energy storage converter assembly, thereby reducing vibration noise during operation. Combined with the wind noise reduction structure, this results in a better noise reduction effect for the cabinet.

[0040] In this embodiment, sound insulation panels 13 are fixed on one side of each of the two fixed partitions 2.

[0041] In this embodiment, a thermoelectric cooler 31 is fixed at the bottom of the cabinet 1. The heat-absorbing surface of the thermoelectric cooler 31 is located between two fixed partitions 2 and a connecting plate 8, and the heat-dissipating surface of the thermoelectric cooler 31 is located at the bottom of the cabinet 1. A heat dissipation fin 32 is fixed at the bottom of the thermoelectric cooler 31. The thermoelectric cooler 31 is an existing structure. The heat dissipation fin 32 can accelerate the heat dissipation of the heat dissipation surface of the thermoelectric cooler 31, thereby improving the cooling efficiency. If you want to speed up the cooling, you can connect a suitable cooling fan to the heat dissipation fin 32.

[0042] In this embodiment, the front end of the cabinet 1 is hinged with two front doors 11, and the rear end of the cabinet 1 is hinged with two rear doors 12. The circulating air duct 10 is located between the cabinet 1, the two fixed partitions 2, the two front doors 11 and the two rear doors 12. The circulating air duct 10 forms a closed internal air duct between the two front doors 11 and the two rear doors 12.

[0043] In this embodiment, support feet 33 are fixedly provided at the four corners of the bottom of the cabinet 1.

[0044] In this embodiment, the sound-absorbing mechanism includes a first sound-absorbing component, a second sound-absorbing component, and a third sound-absorbing component. The first sound-absorbing component is disposed on the left and right side walls inside the cabinet 1; the second sound-absorbing component is disposed on the top and bottom of the cabinet 1; and the third sound-absorbing component is disposed on the two front doors 11 and the two rear doors 12. That is, the first sound-absorbing component, the second sound-absorbing component, and the third sound-absorbing component are respectively disposed on the left, right, top, bottom, front, and back of the circulating air duct 10, so that no wind noise is transmitted when the air flows inside the entire circulating air duct 10.

[0045] In this embodiment, Figures 6 to 7 , Figures 12 to 13 and Figure 15 The first sound-absorbing component includes two first sound-absorbing panels 14 disposed on the left and right side walls inside the cabinet 1. The top and bottom of the two side walls inside the cabinet 1 are provided with first slots 15. The top and bottom of the first sound-absorbing panels 14 extend into the two first slots 15 respectively. A first sound-absorbing cotton layer 16 is fixedly disposed on the inner side of the first sound-absorbing panel 14. A first pull block 17 is fixedly disposed on the front end of the inner side of the first sound-absorbing panel 14.

[0046] The second sound-absorbing component includes two second sound-absorbing panels 18 disposed at the top and bottom of the cabinet 1. The second sound-absorbing panels 18 are disposed between two fixed partitions 2 and four fixed support plates 3. A second sound-absorbing cotton layer 19 is fixedly disposed on the inner side of the second sound-absorbing panel 18. A second pull block 20 is fixedly disposed on the front end of the inner side of the second sound-absorbing panel 18. Two T-shaped slots 21 are opened at the top and bottom of the cabinet 1. Two T-shaped blocks 22 are fixed on the outer side of the two second sound-absorbing panels 18. The T-shaped blocks 22 extend into the two T-shaped slots 21 respectively.

[0047] The third sound-absorbing component includes four third sound-absorbing panels 23 disposed inside the two front doors 11 and the two rear doors 12. A third sound-absorbing cotton layer 24 is fixedly disposed inside the third sound-absorbing panel 23. Insertion slots 25 are provided inside the front doors 11 and the rear doors 12. The third sound-absorbing panel 23 and the third sound-absorbing cotton layer 24 are disposed inside the insertion slots 25. A third pull block 26 is fixedly disposed on the inner side of the third sound-absorbing panel 23 near the middle of the cabinet 1.

[0048] If any of the first, second, or third sound-absorbing components becomes damaged during prolonged use, open the front door 11 and pull the first pull block 17 outwards. The first pull block 17 will move the first sound-absorbing panel 14 and the first sound-absorbing cotton layer 16 outwards, allowing for replacement of the first sound-absorbing panel 14 and the first sound-absorbing cotton layer 16. Pull the second pull block 20 outwards; the second pull block 20 will move the second sound-absorbing panel 18 and the second sound-absorbing cotton layer 19 outwards, causing the second sound-absorbing panel 18 to move... The T-shaped locking block 22 leaves the interior of the T-shaped locking slot 21, allowing the second sound-absorbing panel 18 and the second sound-absorbing cotton layer 19 to be replaced. Similarly, by pulling the third pulling block 26 outward, the third pulling block 26 causes the third sound-absorbing panel 23 and the third sound-absorbing cotton layer 24 to leave the interior of the insertion slot 25, allowing the third sound-absorbing panel 23 and the third sound-absorbing cotton layer 24 to be replaced. The first sound-absorbing panel 14 and the first locking slot 15, the T-shaped locking slot 21 and the T-shaped locking block 22, and the third sound-absorbing panel 23 and the insertion slot 25 are all interference fits.

[0049] The present invention movably installs the first sound-absorbing component, the second sound-absorbing component, and the third sound-absorbing component on the four inner walls of the cabinet 1 and the two front doors 11 and the rear door 12, respectively, making it simple and convenient to replace when damaged. When a sound-absorbing structure is damaged, only the damaged part needs to be replaced, avoiding the waste of resources caused by replacing the entire sound-absorbing structure when a single damage occurs.

[0050] In this embodiment, during operation, the fan 9 is activated, and air enters from the front of the connecting plate 8 between the two fixed partitions 2. Then, blocked by the rear door 12, the air is split to both sides. The split air flows between the two fixed support plates 3 and the first sound-absorbing component, then between the front door 11 and the energy storage converter assembly 7, and then returns to the front of the connecting plate 8. Thus, the air flows back and forth through the circulating air duct 10. The heat generated on the energy storage converter assembly 7 flows with the circulating air, and the heat-absorbing surface of the semiconductor cooling chip 31 absorbs the heat from the air between the two fixed partitions 2. The heat is then dissipated through the heat dissipation fins 32 on its heat-dissipating surface, thus removing heat from the circulating air. This provides good heat dissipation for the energy storage converter assembly 7. Furthermore, the internal circulating heat dissipation avoids the need for ventilation holes on the front and rear doors 11, thereby sealing the interior of the cabinet 1 and reducing noise transmission. Both noise reduction and heat dissipation are effective. The first, second, and third sound-absorbing components are positioned on the left, right, top, bottom, front, and back of the circulating air duct 10, respectively, ensuring no wind noise is transmitted during airflow within the duct. When the energy storage converter assembly 7 is operating, vibrations are transmitted to the mounting plate 6, which in turn transmits these vibrations to the buffer pad 28 and buffer spring 30. The buffer pad 28 and buffer spring 30 cushion and dampen the vibrations of the mounting plate 6 and the energy storage converter assembly 7, reducing noise generated by the operational vibrations of the energy storage converter assembly 7.

[0051] This invention effectively controls wind noise and reduces cabinet noise by setting a closed circulating air duct 10 inside the cabinet 1 and installing a sound-absorbing mechanism around the outside of the circulating air duct 10. The buffer pad 28 and buffer spring 30 in the buffer noise reduction component can buffer the mounting plate 6 and the energy storage converter component 7, thereby reducing the vibration noise of the energy storage converter component 7 during operation. Combined with the wind noise reduction structure, the cabinet has a better noise reduction effect. This embodiment specifically solves the problem in the prior art that if the noise generated by the energy storage converter cabinet is too large during actual use, it will affect the living environment of the surrounding people.

[0052] The advantages of this invention are:

[0053] 1. By setting up a closed circulating air duct inside the cabinet and installing sound-absorbing mechanisms around the outside of the circulating air duct, wind noise can be effectively controlled, thereby reducing the noise of the cabinet. The buffer pads and buffer springs in the buffer noise reduction components can buffer the mounting plate and energy storage converter components, thereby reducing the vibration noise of the energy storage converter components during operation. Combined with the wind noise reduction structure, the cabinet has a good noise reduction effect.

[0054] 2. By circulating the cooled air inside the air duct, the cold air can flow back and forth around the energy storage converter components, resulting in faster heat dissipation and better heat dissipation effect inside the cabinet.

[0055] 3. By movably installing the first, second, and third sound-absorbing components on the four inner walls of the cabinet and the two front and rear doors, it is easy and convenient to replace them when they are damaged. When a sound-absorbing structure is damaged, only the damaged part needs to be replaced, avoiding the waste of resources caused by replacing the entire sound-absorbing structure when a single damage occurs.

[0056] If this invention discloses or relates to components or structural parts that are fixedly connected to each other, then, unless otherwise stated, a fixed connection can be understood as: a fixed connection that can be detached (e.g., using bolts or screws), or a fixed connection that cannot be detached (e.g., riveting, welding). Of course, a fixed connection can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).

[0057] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this invention to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0058] Any component provided by this invention can be assembled from multiple individual components or can be a single component manufactured by a one-piece molding process.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
