[0001] This utility model relates to the field of energy storage cabinet technology, specifically to energy storage cabinet noise reduction equipment and energy storage cabinet. Background Technology

[0002] Energy storage cabinets are the basic units of energy storage devices, housing multiple battery packs. Because the battery packs and other electronic equipment within the cabinet generate heat after prolonged operation, failure to dissipate this heat promptly can lead to performance degradation or even damage. Related technologies typically employ fans or air conditioners to dissipate heat from the cabinet, achieving cooling. However, the airflow from these fans or air conditioners can generate significant noise, negatively impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a noise reduction device for energy storage cabinets and an energy storage cabinet. By setting an air intake noise reduction component on the air intake side and connecting an air outlet noise reduction component on the air outlet side, the noise generated by the energy storage cabinet is reduced, ensuring that the noise generated by the energy storage cabinet is within the range required by the customer.

[0004] This utility model provides the following technical solution: an energy storage cabinet noise reduction device, including at least one air intake noise reduction component connected to the cabinet body and at least one air outlet noise reduction component connected to the side of the cabinet body. The air intake noise reduction component includes an air intake box body, an air inlet is provided on the lower surface of the air intake box body, an air outlet is provided on the side of the air intake box body, a flange is formed on the end face of the air outlet, the flange is connected to the cabinet body, and an air intake porous sound-absorbing plate is also fixed inside the air intake box body. The air intake porous sound-absorbing plate divides the air intake box body into two vertically distributed "┌"-shaped air intake channels, and the air intake porous sound-absorbing plate blocks part of the air inlet. A mixing chamber is formed at the other end of the air intake box body.

[0005] In order to divert the incoming air and increase the contact area between the incoming air and the porous sound-absorbing plate, one end of the porous sound-absorbing plate is located in the middle of the air inlet.

[0006] In order to mix the airflow in different air ducts and cancel out some sound waves, the air inlet box is formed with a first horn mouth on the side near the air outlet. The mixing chamber is the first horn mouth. The small end of the first horn mouth is connected to the air outlet, and the other end is connected to the air inlet box. The other end of the air inlet porous sound-absorbing plate is flush with the large end of the first horn mouth.

[0007] To prevent foreign objects from entering the air inlet box, a protective net is connected to the air inlet side.

[0008] In order to increase the contact area between the perforated sound-absorbing panel and the airflow, the air outlet noise reduction component includes an air outlet box, which is L-shaped, and a plurality of perforated sound-absorbing panels distributed vertically are fixed inside the air outlet box.

[0009] To facilitate the installation of the sound-absorbing panel inside the air outlet box, the perforated sound-absorbing panel includes a first sound-absorbing panel and a second sound-absorbing panel. The first sound-absorbing panel and the second sound-absorbing panel are vertically distributed. The first sound-absorbing panel is inserted from one end of the air outlet box, and the second sound-absorbing panel is inserted from the other end of the air outlet box.

[0010] In order to reduce the air velocity and reduce the impact of the air force on the air outlet box, a second horn is also formed on the air inlet side of the air outlet box.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 2 and 3This utility model provides a technical solution: a noise reduction device for an energy storage cabinet, comprising six air inlet noise reduction components 1 connected to the cabinet body 3 and two air outlet noise reduction components 2 connected to the sides of the cabinet body 3. Each air inlet noise reduction component 1 includes an air inlet box 11, with an air inlet 13 on the lower surface of the air inlet box 11 and an air outlet 14 on the side of the air inlet box 11. A flange is connected to the air outlet 14 and is attached to the cabinet body 3. A porous sound-absorbing panel 15 is fixed inside the air inlet box 11, dividing the air inlet box 11 into two vertically distributed "┌"-shaped air inlet channels. One end of the porous sound-absorbing panel 15 is positioned... Above the air inlet 13, a portion of the air inlet 13 is blocked. A mixing chamber is formed at the other end of the air inlet box 11. Air first enters from the air inlet 13, then turns at a right angle within the air inlet box 11 and flows into the top ventilation pipe 4. At the same time, the perforated sound-absorbing panel 15 divides the air intake into two channels. The sound waves generated by the air in both channels are absorbed by the perforated sound-absorbing panel 15, reducing noise generation. The remaining sound waves enter the mixing chamber between the exhaust port 14 and the perforated sound-absorbing panel 15. The sound waves from the two channels converge in the mixing chamber, and the energy of some of the sound waves cancels each other out, further reducing noise.

[0026] One end of the perforated sound-absorbing panel 15 is located in the middle of the air inlet 13. By partially blocking the air inlet 13, the air is evenly distributed at both the upper and lower ends of the perforated sound-absorbing panel 15, and the sound waves are also distributed vertically, increasing the contact area between the sound waves and the perforated sound-absorbing panel 15.

[0027] The air inlet box 11 has a first horn 16 formed on the side near the air outlet 22. The small end of the first horn 16 is connected to the air outlet 22, and the other end is connected to the air inlet box 11. The other end of the air inlet porous sound-absorbing plate 15 is flush with the large end of the first horn 16. Through the first horn 16, the sound waves in the two channels are mixed and then enter the top ventilation pipe 4, which reduces noise. At the same time, the air in the two channels is mixed, which further reduces the wind speed and reduces the generation of noise.

[0028] A protective net 12 is connected to the side of the air inlet 13. The protective net 12 is used to protect the air inlet 13 and prevent foreign objects from entering the air inlet box 11.

[0029] like Figure 4 and 5 As shown, the air outlet noise reduction component 2 includes an air outlet box 21, which is connected to the side of the cabinet 3 via a flange. The air outlet box 21 is L-shaped, and multiple vertically distributed perforated sound-absorbing panels 25 are fixed inside the air outlet box 21. By absorbing the sound waves inside the air outlet box 21 through the perforated sound-absorbing panels 25, the noise generated by the vibration of the air outlet box 21 when the air is discharged is reduced.

[0030] The multi-hole sound-absorbing panel 25 includes a first sound-absorbing panel and a second sound-absorbing panel, which are vertically distributed. The first sound-absorbing panel is inserted from the air guide port 23 at one end of the air outlet box 21, and the second sound-absorbing panel is inserted from the air outlet 22 of the air outlet box 21. The first sound-absorbing panel and the second sound-absorbing panel are distributed sequentially on both ends of the L-shaped air outlet box 21. The first sound-absorbing panel is used to reduce the noise generated by the wind entering the air outlet box 21, and the second sound-absorbing panel is used to reduce the noise generated by the wind turning and impact vibration of the air outlet box 21, further reducing the noise of the air outlet box 21.

[0031] The air inlet side of the air outlet box 21 is also formed with a second horn 26. The small opening of the second horn 26 is connected to the air inlet 13 of the air outlet box 21. One end of the air outlet porous sound-absorbing plate 25 is flush with the large opening of the second horn 26. The second horn 26 diffuses the air force, reduces the wind speed, further reduces the impact on the air outlet box 21, reduces vibration, and reduces noise.

[0032] like Figure 1 As shown, the present invention provides a technical solution: an energy storage cabinet, including a cabinet body 3, a top ventilation pipe 4 fixed to the cabinet body 3 by welding, a connecting beam 5 bolted to the upper end of the top ventilation pipe 4, and the two ends of the connecting beam 5 connected to the aforementioned air intake noise reduction component 1 by flanges. The air intake noise reduction component 1 is located at both ends of the top ventilation pipe 4. The aforementioned air outlet noise reduction component 2 is connected to one side of the cabinet body 3 by flanges. The lower end of the air outlet noise reduction component 2 is fixed with a support leg 24, which supports the air outlet noise reduction component 2 and keeps it in a horizontal state. By using the air intake noise reduction component 1 and the air outlet noise reduction component 2, the noise generated by the energy storage cabinet is significantly reduced.

[0033] The connecting beam 5 includes a middle connecting part 52 and two end fixing parts 51 located on both sides of the middle connecting part 52. The two end fixing parts 51 are bent and formed on both ends of the middle connecting part 52. The air intake noise reduction component 1 is connected to the lower end of the two end fixing parts 51, which enhances the connection strength between the air intake noise reduction component 1 and the two end fixing parts 51, and transfers the gravity of the air intake noise reduction component 1 to the top ventilation pipe 4, further reducing the pressure on the cabinet 3.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
