However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms 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 application and simplifying the description, and do not 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 application.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] This application provides an integrated energy storage unit, which includes multiple energy storage modules, each of which includes an AC busbar. The energy storage modules may also include a power conversion module for converting the DC power output from the energy storage module 2000 into AC power and collecting it to the AC busbar, or for converting the AC power from the AC busbar into DC power to charge the energy storage module 2000.

[0051] Another type of integrated energy storage unit includes multiple energy storage modules. Each of the multiple energy storage modules includes a DC bus. The power conversion module 3000 of the energy storage module is used to convert and collect the first DC power output from the energy storage module 2000 to the DC bus, or to convert the second DC power from the DC bus to charge the energy storage module 2000. The multiple energy storage modules are arranged in a set direction, and the DC buses of adjacent energy storage modules are plugged into each other to realize the connection of multiple energy storage modules.

[0052] Reference Figure 1 This application provides an energy storage module including a housing 1000. The housing 1000 includes a first assembly shell 1100, an energy storage module 2000, and a first heat dissipation structure 4000. The energy storage module 2000 is assembled in the inner cavity of the first assembly shell 1100. The first heat dissipation structure 4000 is integrally disposed on the outside of the first assembly shell 1100. The first heat dissipation structure 4000 has a plurality of first heat dissipation channels 4100, each of which has a first fluid inlet 4110 and a first fluid outlet 4120.

[0053] As can be seen from the above, when the first heat dissipation structure 4000 and the first assembly shell are integrated, the volume occupied by the first heat dissipation structure in the energy storage module can be reduced, and the gap between the energy storage module and the first heat dissipation structure 4000 is small, resulting in better heat conduction and facilitating efficient heat dissipation of the energy storage module 2000 inside the first assembly shell.

[0054] Reference Figures 1 to 9This application also provides an energy storage module including a housing 1000, an energy storage module 2000, a power conversion module 3000, a first heat dissipation structure 4000, and a second heat dissipation structure 5000. The housing 1000 includes a first assembly shell 1100 and a second assembly shell 1200 that cooperate with each other, forming a closed space for accommodating the energy storage module 2000 and the power conversion module 3000. The housing 1000 also has a fluid collection outlet 1300 located on the outer surface of the housing 1000, used to discharge internal heat to the outside of the housing through a fluid medium. The energy storage module 2000 is assembled in the inner cavity of the first assembly shell 1100, and the power conversion module 3000 is assembled in the inner cavity of the second assembly shell 1200.

[0055] The first heat dissipation structure 4000 is disposed on the outside of the first assembly shell 1100, such as Figure 2 and Figure 3 As shown, the first heat dissipation structure 4000 has a plurality of first heat dissipation channels 4100. Each first heat dissipation channel 4100 has a first fluid inlet 4110 and a first fluid outlet 4120. Cooling fluid can enter from the first fluid inlet 4110, and after balancing the heat generated by the plurality of energy storage modules 2000 through the first heat dissipation channel 4100, it flows out from the first fluid outlet 4120.

[0056] The second heat dissipation structure 5000 is located in the power conversion module 3000, such as Figure 4 As shown, the second heat dissipation structure 5000 has several second heat dissipation channels 5100. The second heat dissipation structure 5000 is disposed on the power conversion module 3000. Each second heat dissipation channel 5100 has a second fluid inlet 5110 and a second fluid outlet 5120. Cooling fluid can enter from the second fluid inlet 5110, absorb the heat generated by the power conversion module 3000 through the second heat dissipation channel 5100, and then flow out from the second fluid outlet 5120.

[0057] It should be noted that the heat from the energy storage module is first transferred to the first heat dissipation structure 4000 and the second heat dissipation structure 5000. Then, the cooler fluid enters the first heat dissipation structure 4000 and the second heat dissipation structure 5000, exchanges heat with them, and thus cools down the first heat dissipation structure 4000 and the second heat dissipation structure 5000.

[0058] The first fluid outlets 4120 of the first heat dissipation structure 4000 and the second fluid outlets 5120 of the second heat dissipation structure 5000 are all connected to the fluid collection outlet 1300, such as Figure 6As shown. This design allows the hot fluid flowing from the first heat dissipation structure 4000 and the second heat dissipation structure 5000 to be collected together and discharged outside the housing 1000 through the fluid collection outlet 1300. Only one fluid collection outlet is needed to discharge the heat from the two heat dissipation structures to the energy storage module, saving heat dissipation space and reducing the volume of the energy storage module.

[0059] During operation, the energy storage module 2000 and power conversion module 3000 generate heat. Cooling fluid (such as air or coolant) enters the first heat dissipation channel 4100 from the first fluid inlet 4110, balancing the heat generated by the energy storage module 2000 before flowing out from the first fluid outlet 4120. Simultaneously, cooling fluid also enters the second heat dissipation channel 5100 from the second fluid inlet 5110, balancing the heat generated by the power conversion module 3000 before flowing out from the second fluid outlet 5120. These high-temperature fluids eventually converge at the fluid collection outlet 1300 and are discharged outside the casing 1000, completing the heat dissipation cycle.

[0060] Therefore, the cooling fluid enters the first heat dissipation channel 4100 from the first fluid inlet 4110, balances the heat generated by the energy storage module 2000, and then flows out from the first fluid outlet 4120. The cooling fluid also enters the second heat dissipation channel 5100 from the second fluid inlet 5110, balances the heat generated by the power conversion module 3000, and then flows out from the second fluid outlet 5120. This allows the energy storage module structure to effectively dissipate heat from the energy storage module 2000 and the power conversion module 3000, ensuring the temperature stability and reliability of the system during long-term operation, extending the service life of the energy storage module, and improving the overall performance of the system.

[0061] The first assembly shell 1100 is provided with a heat dissipation cavity 4200, which has a cavity inlet 4210 and a cavity outlet 4220. The heat dissipation cavity 4200 is a hollow cavity located inside the first assembly shell 1100 for collecting and guiding heat fluid. Figure 6 and Figure 9 As shown, the cavity inlet 4210 is connected to several first fluid outlets 4120 of the first heat dissipation structure 4000, and the cavity outlet 4220 is connected to the fluid collection outlet 1300. This interconnected structure design allows the hot fluid flowing out of the first heat dissipation structure 4000 to be collected through the heat dissipation cavity 4200 and then discharged from the fluid collection outlet 1300, thus fixing the flow direction of the hot fluid.

[0062] like Figure 6 , Figure 7 and Figure 9As shown, a volute plate 4300 is disposed on the outside of the first assembly shell 1100, and a heat dissipation cavity 4200 is formed between the inner wall of the volute plate 4300 and the outer wall of the first assembly shell 1100. The volute plate 4300 includes a connected straight plate region 4310 and a curved plate region 4320. A plurality of first fluid outlets 4120 of the first heat dissipation structure 4000 face the straight plate region 4310. The inner wall of the curved plate region 4320 has a guide surface that guides the flow along the direction from the cavity inlet 4210 to the cavity outlet 4220, thereby forming a volute-shaped flow channel, which causes the cooling fluid to form a vortex in the heat dissipation cavity 4200, thereby enhancing the heat exchange efficiency. This allows the hot fluid flowing out from the first fluid outlet 4120 to form an orderly flow path in the heat dissipation cavity 4200, reducing fluid resistance and improving heat dissipation efficiency.

[0063] In one embodiment, the straight plate region 4310 is basically flat and maintains a certain distance from the outer wall of the first assembly shell 1100. The curved plate region 4320 is arc-shaped, and the distance between the curved plate region 4320 and the outer wall of the first assembly shell 1100 gradually increases from one end to the other, forming a curved heat dissipation cavity 4200, that is, a portion of the cavity wall of the heat dissipation cavity 4200 is designed as a curved surface. This curved surface structural design enables the cooling medium to form accelerated flow within the heat dissipation cavity 4200, enhancing the convective heat transfer effect, while avoiding cooling dead zones. This ensures that the entire outer wall of the first assembly shell 1100 can be effectively cooled, preventing the hot fluid from diffusing in the space of the first assembly shell 1100 and repeatedly conducting heat with the energy storage module 2000, thereby ensuring the heat dissipation efficiency of the energy storage module 2000.

[0064] In a preferred embodiment, the volute plate 4300 is made of a high thermal conductivity metal material, such as aluminum alloy or copper alloy, to further improve heat dissipation efficiency. The outer surface of the volute plate 4300 may also be provided with heat dissipation patterns or coated with a heat dissipation coating to enhance heat dissipation to the external environment.

[0065] In operation, cooling fluid enters the first heat dissipation channel 4100 through the first fluid inlet 4110. During its flow through the first heat dissipation channel 4100, it absorbs heat generated by the energy storage module 2000 and becomes hot fluid, which flows out from the first fluid outlet 4120. The hot fluid then enters the cavity inlet 4210 of the heat dissipation cavity 4200 through the first fluid outlet 4120, gathers inside the heat dissipation cavity 4200, flows to the cavity outlet 4220, and finally exits the housing 1000 through the fluid collection outlet 1300.

[0066] Through the design of the above-mentioned heat dissipation cavity connection structure, an effective connection between the first heat dissipation structure 4000 and the fluid collection outlet 1300 is achieved, forming a complete heat dissipation channel system, which significantly improves the heat dissipation efficiency of the energy storage module, ensures the normal operating temperature of the energy storage module 2000, and extends the service life of the energy storage module.

[0067] The volute plate 4300 is mounted on the side surface of the first mounting shell 1100, and a heat dissipation cavity 4200 is formed between the volute plate 4300 and the side surface of the first mounting shell 1100. This installation method allows the shape of the heat dissipation cavity 4200 to be optimized according to heat dissipation requirements. At the same time, the integrated molding design between the volute plate 4300 and the first mounting shell 1100 can also effectively reduce the volume.

[0068] The first heat dissipation channel 4100 of the first heat dissipation structure 4000 can be in the form of a channel, a slot, or other forms, and is not limited here. For example, Figure 2 , Figure 3 and Figure 9 As shown, the first heat dissipation structure 4000 includes a plurality of first heat dissipation fins 4400, which are assembled on the bottom surface of the first assembly housing 1100. A first channel groove is formed between any two adjacent first heat dissipation fins 4400. This first channel groove is closed on one side, open on one side, and continuous at both ends. Each first channel groove is configured to form a first heat dissipation channel 4100. The first heat dissipation fins 4400 increase the heat dissipation area and improve heat dissipation efficiency.

[0069] The ends of some of the first heat dissipation fins 4400 are connected to the volute plate 4300. This connection method not only enhances the structural strength, but also forms a closed first heat dissipation channel 4100 between some of the first heat dissipation fins 4400, preventing fluid leakage and improving heat dissipation efficiency.

[0070] The second heat dissipation channel 5100 of the second heat dissipation structure 5000 can be in the form of a channel, a slot, or other forms, and is not limited here. For example, Figure 4 As shown, the second heat dissipation structure 5000 includes a plurality of second heat dissipation fins, which are mounted on the surface of the power conversion module 3000. A second channel groove is formed between any two adjacent second heat dissipation fins. This second channel groove is closed on one side, open on one side, and continuous at both ends. Each second channel groove is configured to form a second heat dissipation channel 5100. The second heat dissipation fins increase the heat dissipation area of ​​the power conversion module 3000, thereby improving heat dissipation efficiency.

[0071] In one embodiment, the sides of several second heat dissipation fins furthest from the power conversion module 3000 are connected to the inner wall of the second mounting housing 1200 to enclose several second heat dissipation channels 5100 into a channel structure. This closed channel structure design prevents fluid leakage within the second heat dissipation channels 5100, thereby improving heat dissipation efficiency.

[0072] When the energy storage module is operating, the energy storage module 2000 and the power conversion module 3000 generate heat. Cooling fluid enters the first heat dissipation channel 4100 through the first fluid inlet 4110, absorbs the heat generated by the energy storage module 2000, and then flows into the heat dissipation cavity 4200 through the first fluid outlet 4120. Simultaneously, cooling fluid enters the second heat dissipation channel 5100 through the second fluid inlet 5110, absorbs the heat generated by the power conversion module 3000, and then flows to the fluid collection outlet 1300 through the second fluid outlet 5120. The hot fluid in the heat dissipation cavity 4200, guided by the flow-guiding surface of the volute plate 4300, flows to the fluid collection outlet 1300 through the cavity outlet 4220. Finally, all the hot fluid is discharged from the fluid collection outlet 1300, completing the heat dissipation process.

[0073] The housing 1000 includes a first assembly housing 1100 and a second assembly housing 1200 that cooperate with each other. The first assembly housing 1100 and the second assembly housing 1200 can be bolted together to form a sealed housing structure. The second assembly housing 1200 is provided with a fluid collection outlet 1300, which is located at the top of the second assembly housing 1200 and is used to discharge hot fluid from inside the housing 1000.

[0074] The energy storage module 2000 is assembled in the inner cavity of the first assembly shell 1100, such as... Figure 7 and Figure 9 As shown, several energy storage modules 2000 are connected in series and parallel via electrical connectors to form a complete energy storage system. Furthermore, the energy storage modules 2000 are mounted inside the first assembly housing 1100 via fixed brackets to ensure stability during transportation and use.

[0075] The power conversion module 3000 is assembled in the inner cavity of the second assembly housing 1200, such as... Figure 7 As shown, the power conversion module 3000 includes components such as an inverter, a transformer, and a control circuit board, used to convert the DC power stored in the energy storage module 2000 into AC power, or to convert external AC power into DC power to charge the energy storage module 2000. The power conversion module 3000 generates a large amount of heat during operation, requiring effective heat dissipation to ensure stable operation.

[0076] When the energy storage module is working, the heat generated by the energy storage module 2000 and the power conversion module 3000 is first transferred to the first assembly shell 1100 and the second assembly shell 1200. The cooling medium enters the heat dissipation cavity 4200 through the cavity inlet 4210, and under the guidance of the volute plate 4300, flows along a curved path, fully contacting the outer wall of the first assembly shell 1100, absorbing heat, and then flows out from the cavity outlet 4220. Simultaneously, another portion of the cooling medium enters the first heat dissipation channel 4100 through the first fluid inlet 4110, passes through the first heat dissipation fins 4400, and flows out from the first fluid outlet 4120. The two cooling circuits can work independently or in combination, and ultimately the cooling medium can be discharged uniformly through the fluid collection outlet 1300.

[0077] This dual heat dissipation structure design, especially the heat dissipation cavity 4200 formed by the volute plate 4300, significantly improves the heat dissipation capacity of the energy storage module, ensuring that the energy storage module 2000 and the power conversion module 3000 can remain within a safe temperature range under high load conditions, extending the service life of the equipment and improving system reliability.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
