This not only increases the humidity inside the energy storage cabinet, potentially causing corrosion or damage to batteries and other equipment, but also increases cleaning difficulty, affecting the long-term stable operation of the equipment. Therefore, how to conveniently collect and drain liquid in the event of a liquid cooling pipe leak, preventing coolant accumulation inside the battery compartment, has become a pressing technical problem to be solved.

[0018] The beneficial effects of this utility model are as follows:

[0019] An energy storage device includes multiple battery packs and an energy storage cabinet, with the battery packs spaced apart in a battery compartment. The energy storage cabinet includes a cabinet body, a liquid cooling assembly, and a floor drain. The battery compartment is formed inside the cabinet body. The cabinet body includes a base plate and mounting components. The base plate forms the bottom wall of the battery compartment and has a notch. The base plate is recessed in a direction away from the battery compartment to form a flow channel, which communicates with the notch.

[0038] This utility model provides an energy storage device, including multiple battery packs and an energy storage cabinet, with the battery packs spaced apart in a battery compartment 23. For easier display of the base plate 21 of the battery compartment 23, see attached... Figure 1-12 The energy storage device in the middle is not equipped with a battery pack.

[0039] Specifically, the energy storage cabinet includes a cabinet body 20, a liquid cooling assembly 30, and a floor drain 40. A battery compartment 23 is formed inside the cabinet body 20. The cabinet body 20 includes a base plate 21 and a mounting component 22. The base plate 21 forms the bottom wall of the battery compartment 23 and has a notch 211. The base plate 21 is recessed away from the battery compartment 23 to form a guide channel 212, which communicates with the notch 211. The mounting component 22 is located at the notch 211 and connected to the base plate 21. The liquid cooling assembly 30 includes a liquid cooling pipe 31, which is located in the battery compartment 23 and connected to the cabinet body 20. The projection of the liquid cooling pipe 31 on the base plate 21 at least partially overlaps with the projection of the guide channel 212. The liquid cooling pipe 31 is used to transport coolant. The floor drain 40 is assembled to the mounting component 22 and is used to drain liquid from inside the battery compartment 23.

[0040] In practical applications, by forming a notch 211 on the base plate 21 and recessing it in a direction away from the battery compartment 23 to form a guide channel 212, the coolant discharged from the liquid cooling pipe 31 or any coolant that may leak is effectively guided to the floor drain 40, thereby preventing coolant from accumulating on the base plate 21. This design not only effectively controls the flow path of the coolant and prevents coolant from stagnating inside the energy storage tank, but also ensures the reliability of the cooling system and reduces potential safety hazards caused by coolant accumulation. Simultaneously, the projection of the liquid cooling pipe 31 at least partially overlaps with the projection of the guide channel 212, which helps improve the guiding efficiency of the coolant and ensures that the coolant can quickly flow to the floor drain 40.

[0041] In this embodiment, the cross-section of the guide channel 212 is triangular; in other embodiments, the cross-section of the guide channel 212 may also be trapezoidal. In this embodiment, the depth of the guide channel 212 is h, where h ≥ 15 mm.

[0042] In one embodiment, see Figure 2 , Figure 3 , Figure 6 and Figure 9 The base plate 21 includes a first guide plate 213 and a second guide plate 214 connected to each other. The first guide plate 213 and the second guide plate 214 are both inclined in the horizontal direction. The first guide plate 213 and the second guide plate 214 form the bottom wall of the guide groove 212. The first guide plate 213 and the second guide plate 214 are respectively connected to the mounting member 22. The first guide plate 213 extends away from the battery compartment 23 in the direction toward the mounting member 22, and the second guide plate 214 extends away from the battery compartment 23 in the direction toward the mounting member 22.

[0043] In practical applications, by tilting the first guide plate 213 and the second guide plate 214 relative to each other to form the sidewall of the guide channel 212, the end of the guide channel 212 near the drain 40 is lower than the end away from the drain 40. This structural design allows the coolant to flow automatically to the drain 40 by gravity without external drive, ensuring that the guide channel 212 can always effectively guide the coolant to the drain 40, effectively preventing coolant accumulation on the base plate 21, further optimizing the coolant discharge and collection process, reducing possible coolant leakage or water accumulation problems, and thus improving the safety and reliability of the energy storage cabinet.

[0044] Furthermore, the included angle between the first guide vane 213 and the second guide vane 214 is A, where 100°≤A≤135°.

[0045] Further, see Figure 3A folded edge 217 is formed at the connection between the first guide plate 213 and the second guide plate 214. The bottom plate 21 includes a first reinforcing part 215 and a second reinforcing part 216. The first reinforcing part 215 is arranged perpendicular to the first guide plate 213, and the second reinforcing part 216 is arranged perpendicular to the second guide plate 214. The first reinforcing part 215 and the second reinforcing part 216 are respectively arranged on both sides of the folded edge 217.

[0046] In practical applications, the base plate 21 is manufactured using sheet metal. A first guide plate 213 and a second guide plate 214 are formed by bending at the folded edge 217, thereby enabling the guide channel 212 to effectively guide airflow. The base plate 21 is bent circumferentially along the first guide plate 213 and the second guide plate 214 to form a first reinforcing part 215 and a second reinforcing part 216. The first reinforcing part 215 and the second reinforcing part 216 are parallel to the side panel of the cabinet 20, allowing them to fit snugly against the side panel of the cabinet 20, facilitating the connection between the base plate 21 and the side panel of the cabinet 20 via the first reinforcing part 215 and the second reinforcing part 216. When the first reinforcing part 215 and the side plate of the cabinet 20, and the second reinforcing part 216 and the side plate of the cabinet 20 are connected by welding, the first reinforcing part 215 and the second reinforcing part 216 can increase the area of ​​the welded joint, thereby improving the connection strength. If bolted connection is used, the first reinforcing part 215 and the second reinforcing part 216 can provide a carrier for the bolt to pass through, thereby improving the connection strength. Furthermore, repeated bending of the base plate 21 can significantly improve the overall strength of the base plate 21, ensuring that the base plate 21 is not easily deformed or damaged under the weight of the sodium-ion battery pack and the cabinet 20, thereby improving the stability and durability of the base plate 21.

[0047] In one embodiment, see Figure 2 , Figure 3 and Figure 9 The mounting part 22 is recessed in the direction away from the battery compartment 23 to form a first clearance groove 221. The first clearance groove 221 is connected to the battery compartment 23 through a notch 211, and part of the liquid cooling pipe 31 passes through the first clearance groove 221.

[0048] In practical applications, by providing a first clearance groove 221 on the mounting component 22 facing away from the battery compartment 23, the liquid cooling pipe 31 can be inserted into this groove, thereby reducing the space occupied by the liquid cooling pipe 31 inside the battery compartment 23. This design allows for more efficient use of the space inside the battery compartment 23, helps optimize the layout of wiring within the battery compartment 23, and also facilitates the fixing and assembly of wiring harnesses. By making reasonable use of space, other components inside the battery compartment 23 can be better arranged, thereby improving the space utilization rate of the battery compartment 23 and enhancing the design flexibility and assembly efficiency of the overall energy storage cabinet.

[0049] Further, see Figure 2The liquid cooling assembly 30 includes a drain valve 32, which is disposed on the liquid cooling pipe 31 through the first relief groove 221. The drain valve 32 is used to drain the coolant in the liquid cooling pipe 31.

[0050] In practical applications, operators can easily open the drain valve 32 when needed, allowing the coolant in the liquid cooling pipe 31 to flow directly into the first clearance tank 221. The coolant then flows through the first clearance tank 221 to the floor drain 40 and finally out of the battery compartment 23. This design makes coolant drainage simpler and more efficient, facilitating coolant replacement and collection by operators, reducing the hassle of coolant leaks or replacements, and also helps maintain the cleanliness and ease of maintenance of the energy storage cabinet.

[0051] Optionally, refer to Figure 2 The mounting component 22 includes an assembly part 222 and a connecting part 223. The assembly part 222 is located on the side of the base plate 21 away from the battery compartment 23. The assembly part 222 is connected to the base plate 21 through the connecting part 223. The assembly part 222 and the connecting part 223 are used to form the side wall of the first clearance groove 221. The assembly part 222 has an assembly hole, and the floor drain 40 is assembled in the assembly hole.

[0052] In practical applications, by providing an assembly part 222 and a connecting part 223 on the mounting component 22, the sidewall of the first clearance groove 221 can be effectively formed. The assembly part 222 is located on the side of the base plate 21 away from the battery compartment 23 and is connected to the base plate 21 via the connecting part 223. This design makes the structure of the base plate 21 and the mounting component 22 more stable and functionally clear. The assembly holes of the assembly part 222 provide a convenient interface for installing the floor drain 40. This structure optimizes the assembly process of the energy storage cabinet, making the installation of the floor drain 40 easier.

[0053] Furthermore, referring to Figure 2 , Figure 4 , Figure 6 and Figure 9 The mounting component 22 includes a flow guide 224, which is connected to the connecting part 223 and the assembly part 222 respectively. The end of the flow guide 224 connected to the assembly part 222 gradually approaches the battery compartment 23 from the relatively far end. The flow guide 224 is used to guide the liquid in the first relief groove 221 to the floor drain 40. The flow guide 224, the assembly part 222 and the connecting part 223 are connected to each other, and the flow guide 224, the assembly part 222 and the connecting part 223 together form the side wall of the first relief groove 221.

[0054] In practical applications, the guide section 224 is inclined so that the end of the guide plate near the floor drain 40 is lower than the end that is relatively far away from the floor drain 40. This helps to ensure that the coolant is smoothly guided to the floor drain 40 through the first clearance groove 221. This design can maximize the flow efficiency of the coolant and ensure the effective discharge of the liquid.

[0055] In one embodiment, reference is made to Figure 6 , Figure 10 , Figure 11 and Figure 12 The cabinet 20 contains an electrical compartment 24. The cabinet 20 includes a first partition 25 and a second partition 26 connected to each other. The first partition 25 has a perforation 261 for the liquid cooling pipe 31 to pass through. The first partition 25 and the second partition 26 are located between the battery compartment 23 and the electrical compartment 24, forming a receiving channel 27 between them. The energy storage cabinet includes a sealing part 50, which is located between the perforation 261 and the receiving channel 27. The sealing part 50 is connected to both the first partition 25 and the second partition 26, and is used to seal the receiving channel 27.

[0056] In practical applications, the containment channel 27 is used to install rock wool or other materials to improve the thermal insulation effect of the battery compartment 23, reduce heat exchange between electrical equipment and battery pack, and the containment channel 27 is equipped with a frame 80 to improve the strength of the cabinet 20. By setting the sealing part 50 to effectively isolate the perforation 261 and the containment channel 27, not only can the entry of liquid into the containment channel 27 be reduced, but the erosion of water vapor on the thermal insulation material (such as rock wool) and the frame 80 in the containment channel 27 can also be significantly reduced. This allows the insulation layer 70 to maintain its performance for a long time, avoiding the decrease in thermal insulation effect or material aging due to water vapor intrusion, thereby improving the service life of the cabinet 20.

[0057] In this embodiment, the first partition 25 is disposed on the side of the receiving channel 27 near the battery compartment 23, and the first partition 25 forms the side wall of the battery compartment 23. The second partition 26 is disposed on the side of the receiving channel 27 near the electrical compartment 24, and the second partition 26 forms the side wall of the electrical compartment 24. In other embodiments, the second partition 26 may also be disposed on the side of the receiving channel 27 near the battery compartment 23, in which case the second partition 26 forms the side wall of the battery compartment 23, and the first partition 25 is disposed on the side of the receiving channel 27 away from the battery compartment 23, and the first partition 25 forms the side wall of the electrical compartment 24.

[0058] Furthermore, referring to Figure 5 , Figure 6 , Figure 11 and Figure 12The first partition 25 has an operating port 251, and the sealing part 50 has a clearance channel 51. The operating port 251 is connected to the perforation 261 through the clearance channel 51. The projection of the perforation 261 is located inside the projection of the operating port 251 on the plane where the first partition 25 is located.

[0059] In practical applications, by designing the area of ​​the operating port 251 to be larger than the area of ​​the perforation 261, the liquid cooling tube 31 can be positioned by the perforation 261 during installation, thus preventing excessive movement or displacement of the liquid cooling tube 31. The larger area of ​​the operating port 251 allows operators to easily reach into the clearance channel 51 to access and operate the liquid cooling tube 31, providing greater flexibility and convenience. This design effectively improves the installation efficiency of the liquid cooling tube 31, reduces time wastage or installation difficulty caused by inconvenient operation, and ensures that the liquid cooling tube 31 maintains a stable position in the perforation 261, avoiding unnecessary loosening or displacement. This layout enhances the efficiency of the installation process.

[0060] In this embodiment, the perforation 261 is a circular hole corresponding to the diameter of the liquid cooling pipe 31, the operating hole is a square hole, and the cross-sectional shape and area of ​​the clearance channel 51 are the same as those of the operating hole. In other embodiments, the operating hole can also be set as a circle, triangle, or other shapes.

[0061] In one embodiment, reference is made to Figure 1 The energy storage cabinet includes a dehumidification component 60, which is located on the side of the battery compartment 23 near the floor drain 40 and is assembled into the cabinet body 20.

[0062] In practical applications, by installing a dehumidifier 60 on the side of the battery compartment 23 near the drain 40, the humidity inside the battery compartment 23 can be effectively reduced, preventing corrosion, battery performance degradation, or other potential problems caused by moisture accumulation. The placement of the dehumidifier 60 close to the drain 40 allows for more effective drainage, preventing liquid buildup and ensuring a dry and stable environment in the battery compartment 23. A flexible hose needs to be connected to the dehumidifier 60 for drainage; the liquid flows out through the hose. Positioning the dehumidifier 60 on the side opening into the drain 40 facilitates proper alignment of the hose's outlet with the drain 40, thus ensuring efficient drainage.

[0063] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0064] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0065] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
