[0044] See Figures 1 to 4 As shown, this application provides an energy storage cabinet, including: a cabinet body 1, a partition assembly 2, a water-cooled unit 3, and a PCS device 4. The cabinet body 1 has a battery cavity 11 and an electrical cavity 12. The partition assembly 2 is disposed in the electrical cavity 12, and the partition assembly 2 divides the electrical cavity 12 into multiple cavities. Each cavity includes at least a water-cooled unit cavity 122 and a PCS cavity 121. The water-cooled unit cavity 122 and the PCS cavity 121 are isolated from each other. A water-cooled unit exhaust port 141 and a PCS exhaust port 142 are disposed on the cabinet body 1 (the rear part of the cabinet body). The water-cooled unit exhaust port 141 is connected to the water-cooled unit cavity 122, and the PCS exhaust port 142 is connected to the PCS cavity 121. The water-cooled unit 3 is disposed in the water-cooled unit cavity 122, and the PCS device 4 is disposed in the PCS cavity 121.

[0045] In the energy storage cabinet provided in this embodiment, the battery chamber 11 is used to house battery packs, for example, multiple battery packs can be housed within the battery chamber 11. The partition assembly 2 is disposed within the electrical chamber 12, which can divide the electrical chamber 12 into multiple chambers, including a distribution chamber 123 for accommodating the distribution cabinet 9, in addition to the water chiller chamber 122 and the PCS chamber 121. The cabinet body 1 is provided with corresponding exhaust vents for the water chiller chamber 122 and the PCS chamber 121, allowing heat to be discharged independently from the PCS chamber 121 and the water chiller chamber 122, completely eliminating heat interference between the two chambers and significantly improving heat dissipation efficiency and system stability.

[0046] The partition assembly 2 may be at least partially made of insulating material to physically isolate the various chambers and prevent heat from penetrating from one chamber to another. For example, the partition assembly 2 may include two layers of galvanized steel sheets and insulating material located between the two layers of galvanized steel sheets. The galvanized steel sheets serve as physical insulation and enhance structural strength, while the insulating material reduces heat penetration.

[0047] The partition assembly 2 may include a longitudinal partition 21 to divide the electrical cavity 12 into two cavities, namely the water turbine cavity 122 and the PCS cavity 121. The partition assembly 2 may also include a horizontal partition 22, with the longitudinal partition 21 vertically connected to the horizontal partition 22. The longitudinal partition 21 and the horizontal partition 22 divide the electrical cavity 12 into the upper water turbine cavity 122 and the PCS cavity 121 arranged sequentially from left to right, and the lower power distribution cavity 123, which is used to house the power distribution cabinet 9.

[0048] PCS unit 4 is electrically connected to the battery pack. PCS unit 4 can control the charging and discharging process of the battery pack and realize the conversion between DC and AC power. PCS unit 4 can not only directly supply power to AC loads, but also build a bridge between the power grid and the energy storage cabinet to realize bidirectional energy flow. Water-cooled unit 3 (or liquid-cooled unit) is used to cool each battery pack, so that the battery pack maintains good operating condition.

[0049] In some possible implementations, the cabinet 1 is also provided with a water turbine air inlet 131 and a PCS air inlet 132. The water turbine air inlet 131 is connected to the water turbine cavity 122, and the PCS air inlet 132 is connected to the PCS cavity 121. The water turbine air inlet 131 and the PCS air inlet 132 are located on one side of the cabinet 1, and the water turbine exhaust outlet 141 and the PCS exhaust outlet 142 are located on the other side of the cabinet 1.

[0050] In this embodiment, the cabinet 1 may have two opposing shell walls. The water chiller air inlet 131 and the PCS air inlet 132 are located on one shell wall, while the water chiller exhaust outlet 141 and the PCS exhaust outlet 142 are located on the other shell wall. This separates the air inlets and outlets, preventing heat discharged from one of the PCS cavity 121 and the water chiller cavity 122 from entering the other and causing heat interference. Furthermore, the two air inlets and two air outlets are located on opposite sides of the cabinet 1, avoiding a tortuous airflow path, achieving directional exhaust, reducing wind resistance, significantly improving heat dissipation efficiency, and ensuring rapid heat removal from the cabinet 1.

[0051] In some possible implementations, the energy storage cabinet includes a fan assembly 5 disposed within the PCS cavity 121 and near the PCS exhaust port 142.

[0052] Under the action of the fan assembly 5, outside air enters the PCS cavity 121 through the PCS inlet 132, exchanges heat with the PCS device 4, and is then discharged through the PCS exhaust outlet 142. The arrangement of the PCS inlet 132, PCS exhaust outlet 142, and fan assembly allows for precise control of the exhaust path of the PCS cavity 121. A hot air exhaust outlet is provided on the casing of the water-cooled unit 3. The cooling fan 31 inside the water-cooled unit 3 is located at the hot air exhaust outlet. Under the action of the cooling fan 31 inside the water-cooled unit 3, outside air enters the water-cooled chamber 122 through the water-cooled unit inlet 131 and is finally discharged through the water-cooled unit exhaust outlet 141. The precise control of the exhaust path of the water-cooled chamber 122 is achieved through the positioning of the water-cooled unit exhaust outlet 141, the water-cooled unit inlet 131, and the hot air exhaust outlet of the water-cooled unit 3. The heat in the water chamber 122 and the PCS chamber 121 can be completely isolated and discharged, ensuring that the two can dissipate heat independently, thus improving the stability and reliability of the system.

[0053] Through the above structural design, the energy storage cabinet of this application has a high-efficiency heat dissipation effect, which not only improves the working efficiency of the energy storage cabinet, but also reduces equipment damage or obsolescence caused by overheating, thereby extending the service life of the equipment, reducing the frequency of equipment replacement, and reducing the negative impact on the environment.

[0054] In some possible implementations, the fan assembly 5 includes a plurality of fans, each of which is arranged sequentially at intervals along the extension direction of the PCS exhaust port 142.

[0055] In this embodiment, both the water chiller exhaust port 141 and the PCS exhaust port 142 can be longitudinally extending strip-shaped openings. To ensure that hot air can be smoothly and evenly discharged from the PCS exhaust port 142, in this embodiment, the fan assembly 5 includes multiple fans, which are arranged sequentially at intervals along the length of the PCS exhaust port 142, thereby increasing the efficiency of hot air discharge. Instead of a separate fan being installed inside the water chiller chamber 122, the cooling fan 31 built into the water-cooled unit 3 is used to provide airflow power.

[0056] In some possible implementations, the energy storage cabinet includes a PCS air guide shroud 6 disposed within the PCS cavity 121, with one port of the PCS air guide shroud 6 facing the PCS exhaust port 142 and the other port of the PCS air guide shroud 6 facing the PCS device 4, and the fan assembly located between the PCS device 4 and the PCS exhaust port 142.

[0057] The PCS air guide hood 6 is designed to precisely guide the flowing air in the PCS cavity 121 to the PCS exhaust port 142, accurately control the exhaust path, reduce wind resistance, and improve exhaust efficiency.

[0058] In some possible implementations, the fan assembly 5 includes a fan bracket 51 that covers the port of the PCS air guide shroud 6 on the side near the PCS device 4, and each of the fans is mounted on the fan bracket 51.

[0059] The fan bracket 51 can be a strip plate. The fan bracket 51 can extend longitudinally, that is, extend along the extension direction of the PCS exhaust port 142. Multiple through holes are provided on the fan bracket 51, and a fan is installed on each through hole.

[0060] In some possible implementations, the energy storage cabinet includes a water chiller shroud 7, which is disposed within the water chiller chamber 122. One side of the shroud 7 faces the hot air exhaust port of the water-cooled unit 3, and the other side faces the water chiller exhaust port 141. The shroud 7 facilitates the precise guidance of the flowing air within the water chiller chamber 122 to the water chiller exhaust port 141, accurately controlling the exhaust path, reducing wind resistance, and improving exhaust efficiency.

[0061] In some possible implementations, the cross-sectional area of ​​the PCS air guide shroud 6 and the water chiller air guide shroud 7 gradually decreases in the direction from the PCS air inlet 132 to the PCS air outlet 142. The gradually narrowing structural design of the PCS air guide shroud 6 and the water chiller air guide shroud 7 has the function of converging hot air at the wide end (the end closer to the PCS device or water-cooled unit) and realizes the precise guidance of air to the exhaust outlet at the narrow end.

[0062] In some possible implementations, a sealing gasket is provided between the edge of the side port (small end) of the PCS air guide hood 6 away from the PCS device 4 and the inner wall of the cabinet 1, and a sealing gasket is provided between the edge of the side port (small end) of the water chiller air guide hood 7 away from the water chiller unit 3 and the inner wall of the cabinet 1, to prevent air leakage and facilitate ventilation.

[0063] In some possible implementations, the cabinet 1 includes a cabinet body, a front door 13, and a rear door 14. Both the front door 13 and the rear door 14 are movably mounted on the cabinet body, located on opposite sides of the cabinet body. The front door 13 is provided with the water chiller air inlet 131 and the PCS air inlet 132, while the rear door 14 is provided with the water chiller exhaust outlet 141 and the PCS exhaust outlet 142. The front door 13 and the rear door 14 can be understood as belonging to two opposite shell walls as described above.

[0064] In some possible implementations, the water turbine air inlet 131, the PCS air inlet 132, the water turbine exhaust outlet 141, and the PCS exhaust outlet 142 are all covered with louvers 8. Each air guide can extend to the peripheral edge of the corresponding louver 8. Alternatively, the air guide can be directly connected to the louver 8.

[0065] The air guide cover and louvers 8 have a simple structural design, uncomplicated manufacturing process, and low production cost. Compared with traditional multi-layer air duct designs, the embodiments of this application reduce material usage and production steps, lowering production costs. Furthermore, due to simplified maintenance operations, they further reduce costs during later use.

[0066] The design combining the air guide shroud and louvers 8 enables directional exhaust of hot airflow within the PCS cavity 121 and water turbine cavity 122, avoiding heat interference and reducing the complexity of the air duct. This structure allows heat from the energy storage cabinet to be directly and rapidly expelled from the cabinet 1, improving heat dissipation efficiency and ensuring stable system operation.

[0067] In this application, at least some of the structures can adopt a modular design. For example, the partition assembly 2, PCS air guide shroud 6, fan bracket 51, water turbine air guide shroud 7, and louvers 8 all adopt a detachable structure, which facilitates cleaning, replacement, or adjustment. Each chamber can also be flexibly adjusted according to different equipment load requirements. This enhances the adaptability of the energy storage cabinet, meets the heat dissipation requirements under different operating conditions, and reduces the complexity of later maintenance.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
