[0002] With the rapid development of new energy vehicles, a large number of power batteries are entering their retirement period, and commercial and industrial energy storage systems made from entire packs of retired batteries are beginning to be widely used. As the core equipment of an energy storage system, the internal environment of the energy storage cabinet is crucial to battery performance and system stability. Especially in harsh environments such as high temperature, low temperature, and high humidity, second-generation batteries are more prone to aging and damage than new batteries, affecting the safety and efficiency of the energy storage system. The layout of entire packs of second-generation batteries in the energy storage cabinet needs to consider the size, weight, and heat dissipation requirements of the battery pack, which may lead to reduced space utilization and increased difficulty in airflow design. An unreasonable airflow layout may also affect air circulation and heat dissipation, further exacerbating thermal management problems. Utility Model Content

[0026] 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.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-7 This utility model provides a duct structure for energy storage cabinets used in industrial and commercial applications with tiered and fully packaged storage, comprising:

[0029] The air inlet assembly is located at the front of the energy storage cabinet 1 and is connected to the air outlet of the liquid-cooled air conditioner 3.

[0030] The air outlet assembly is located at the rear of the energy storage cabinet 1. The air outlet assembly is connected to the heat dissipation end of the liquid-cooled air conditioner 3 and the power distribution unit 2. A fan 7 is installed inside the air outlet assembly.

[0031] The distributed air duct component has one end connected to the air inlet component through the air outlet of the liquid-cooled air conditioner 3, and the other end of the distributed air duct component is correspondingly set with several battery packs 4.

[0032] The air outlet isolation enclosure 8 is connected between the air outlet assembly and the heat dissipation end of the liquid-cooled air conditioner 3 and the power distribution unit 2. The air outlet isolation enclosure 8 is used to isolate the distributed air duct assembly from the air outlet assembly.

[0033] The main function of the air inlet assembly is to introduce outside air into the energy storage cabinet 1 through the air outlet of the liquid-cooled air conditioner 3, forming a low-temperature airflow. The main function of the air outlet assembly is to exhaust hot air from the energy storage cabinet 1. The main function of the fan 7 is to provide power for the airflow within the energy storage cabinet 1. The main function of the distributed air duct assembly is to use the low-temperature airflow to reduce the temperature of several battery packs 4. The main function of the exhaust isolation enclosure 8 is to prevent the mixing of cold and hot air within the energy storage cabinet 1, and to ensure that the airflow generated by the fan has a certain direction and speed, preventing airflow diffusion and improving heat exchange efficiency. Overall, this invention, by optimizing the air duct structure within the energy storage cabinet, effectively prevents the mixing of cold and hot air, achieving uniform airflow and efficient heat dissipation inside the energy storage cabinet. This ensures that the secondary battery packs and various electrical components inside the energy storage cabinet operate within their optimal operating temperature range, thereby improving the overall efficiency and economic benefits of the energy storage cabinet.

[0034] Further optimization of the scheme: the distributed air duct component can use a partition structure to wrap several battery packs 4, so that cold air passes through the battery packs 4 in sequence, which helps to cool the battery packs 4, and finally enters the air outlet isolation enclosure 8, so that the fan can exhaust the hot air.

[0035] Further optimization of the scheme: the air inlet assembly includes several air inlets 5, which are located at the bottom of the front side wall of the energy storage cabinet 1. An air inlet cover 14 is fixedly connected to the inner side of the front side wall of the energy storage cabinet 1, and the air inlets 5 are connected to the air outlet of the liquid-cooled air conditioner 3 through the air inlet cover 14.

[0036] Further optimization of the scheme: the air outlet assembly includes several air outlets 6, which are opened on the top of the rear side wall of the energy storage cabinet 1. An air outlet cover 15 is fixedly connected to the inner side of the rear side wall of the energy storage cabinet 1. The air outlet cover 15 is connected to the air outlet isolation cover 8. The fan 7 is fixedly connected to the air outlet cover 15.

[0037] The scheme is further optimized. The air outlet isolation enclosure 8 includes an upper enclosure 81 and a lower enclosure 82. The top of the upper enclosure 81 and the bottom of the lower enclosure 82 are connected. The two ends of the upper enclosure 81 are fixedly connected to the heat dissipation end of the power distribution unit 2 and the rear side wall of the energy storage cabinet 1. The two ends of the lower enclosure 82 are fixedly connected to the heat dissipation section of the liquid-cooled air conditioner 3 and the rear side wall of the energy storage cabinet 1, respectively. The air outlet enclosure 15 is set inside the upper enclosure 81.

[0038] like Figure 1 and Figure 4 As shown, the lower enclosure 82 and the upper enclosure 81 form a convex structure, and the end of the air outlet isolation enclosure 8 near the air outlet enclosure 15 is tapered to increase the airflow speed.

[0039] The heat discharged by the liquid-cooled air conditioner 3 can enter the upper enclosure 81 from the lower enclosure 82. At the same time, the heat generated by the power distribution unit 2 enters the upper enclosure 81 and is finally discharged from the air outlet 6 through the fan 7.

[0040] The design has been further optimized by installing drainage components inside the air inlet enclosure 14 and the air outlet enclosure 15.

[0041] The drainage components on the air intake enclosure 14 include several waterproof louvers 9, which are fixedly connected at an angle between two opposite side walls of the air intake enclosure 14. A first layer of water guide plate 10 is provided below the bottom waterproof louvers 9. Several drainage holes 13 are provided on the front side wall of the energy storage cabinet 1, and the first layer of water guide plate 10 is connected to the several drainage holes 13.

[0042] like Figure 2 and Figure 3 As shown, the lower ends of the waterproof louvers 9 in the air inlet enclosure 14 and the air outlet enclosure 15 are located on the outside of the energy storage cabinet body 1, which is conducive to water dripping along the waterproof louvers 9 onto the first water guide plate 10, and the water is discharged from the energy storage cabinet body 1 through the drain hole 13 by the first water guide plate 10.

[0043] The design has been further optimized by installing dustproof nets 12 inside the air inlet enclosure 14 and the air outlet enclosure 15 respectively.

[0044] The dustproof net 12 located inside the air inlet enclosure 14 is vertically fixed between the two opposite side walls of the air inlet enclosure 14. The dustproof net 12 is located on the air outlet side of the waterproof louver 9. A second layer of water guide plate 11 is also inclinedly arranged inside the air inlet enclosure 14. The second layer of water guide plate 11 is arranged corresponding to the dustproof net 12. The second layer of water guide plate 11 is located below the first layer of water guide plate 10.

[0045] like Figure 2 and Figure 3 As shown, the dustproof net 12 is made of aluminum alloy. The main function of the dustproof net 12 is to prevent impurities in the air from entering the energy storage cabinet 1. At the same time, water droplets condensed on the dustproof net 12 can be discharged from the drain hole 13 through the second water guide plate 11 after falling.
