Description

Technical Field

[0001] This utility model relates to the field of energy storage electrical equipment technology, and in particular to an energy storage cabinet and its cabinet body. Background Technology

[0002] In the current energy sector, the development of energy storage technology is crucial. With the increasing use of renewable energy, energy storage cabinets, as an important energy storage device, have been widely applied.

[0003] Batteries are the core component of energy storage cabinets, and their performance and lifespan are significantly affected by temperature. Under different environmental conditions, especially in extreme temperature environments, the charging and discharging efficiency, capacity, and safety of batteries can be severely impacted. For example, at excessively low temperatures, the charging and discharging efficiency of batteries will decrease significantly, and the battery capacity will also be affected, leading to a reduction in the overall energy storage and supply capabilities of the energy storage cabinet. In cold regions or during winter, for instance, the performance of energy storage batteries will be greatly reduced due to low temperatures. On the other hand, existing insulation technologies are often costly, complex to implement, or their insulation effects are insufficient to meet the needs of practical applications.

[0004] Currently, existing energy storage cabinet battery compartments have certain shortcomings in terms of thermal insulation performance. On the one hand, traditional battery compartment structures are relatively simple in design and lack effective insulation measures, making it difficult to maintain the batteries within a suitable temperature range. On the other hand, traditional insulation materials and structures may have problems such as unsatisfactory insulation effects, large space occupation, heavy weight, and high cost. For example, some common insulation materials such as rock wool, although they have certain insulation performance, may have disadvantages such as complex installation and susceptibility to moisture, affecting their long-term insulation effect and service life.

[0005] Therefore, in order to improve the performance and lifespan of energy storage cabinet batteries and ensure the safe and stable operation of energy storage systems, developing a new type of energy storage cabinet is an urgent problem to be solved. Utility Model Content

[0006] Therefore, it is necessary to provide an energy storage cabinet and its enclosure to address the aforementioned technical problems.

[0007] An energy storage cabinet includes: a cabinet body and a partition, wherein the cabinet body has a first placement chamber and a second placement chamber inside, and the first placement chamber and the second placement chamber are separated by the partition;

[0008] The partition includes multiple insulated boxes that are spliced ​​together in sequence. Each insulated box has an internal cavity, and each cavity contains an aluminum foil foam layer.

[0009] In one embodiment, the partition further includes an isolation support frame connected to the cabinet body and disposed between the first placement chamber and the second placement chamber. Each of the insulated boxes is disposed on the isolation support frame, and adjacent insulated boxes are connected through the isolation support frame.

[0010] In one embodiment, the isolation support frame includes multiple crossbeams and multiple longitudinal columns. Each crossbeam and each longitudinal column is connected to the cabinet body. The crossbeams and each longitudinal column are staggered to form multiple mounting positions. Each insulation box is disposed on one of the mounting positions.

[0011] In one embodiment, a bracket is also included, which is fixed to the side of the isolation support frame facing the first placement chamber.

[0012] In one embodiment, the bracket includes a support frame and fasteners, the support frame being secured to the isolation support frame by the fasteners.

[0013] In one embodiment, the fastener is a screw.

[0014] In one embodiment, the bracket further includes a limiting portion disposed at the first end of the support frame.

[0015] In one embodiment, the insulated box has an opening that communicates with the cavity, and the aluminum foil foam layer is installed in the cavity through the opening, with the opening facing the first placement chamber.

[0016] In one embodiment, the material of the insulated box is sheet metal.

[0017] An energy storage cabinet includes a cabinet body, an electrical unit, a battery unit, and a water-cooling unit as described in any of the above embodiments. The battery unit is disposed in a first placement chamber, the water-cooling unit is disposed in a second placement chamber, and a third placement chamber is also disposed inside the cabinet body. The third placement chamber is disposed on one side of the second placement chamber, and the electrical unit is disposed in the third placement chamber.

[0018] The aforementioned energy storage cabinet and its body have partitions composed of multiple spliced ​​insulated boxes. Each insulated box contains an aluminum foil foam layer. When the partitions are installed inside the cabinet body, the first and second placement chambers are isolated by the partitions. The low thermal conductivity of the aluminum foil foam layer and the air barrier effect of the cavity work together to suppress heat transfer, significantly improving the temperature stability of the battery compartment in extreme environments. When maintenance or replacement of local insulation structures is required, only the corresponding insulated box needs to be disassembled, without removing the entire partition, and it can be flexibly arranged to accommodate different sized chambers. The aluminum foil foam layer can prevent moisture penetration, avoiding the problem of reduced insulation performance of traditional rock wool after it becomes damp. Through the above structure, while achieving efficient insulation, it solves the technical defects of traditional energy storage cabinet partitions, such as large weight, complex installation, and susceptibility to failure in humid environments.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Example 1

[0025] In this embodiment, as Figures 1 to 2 As shown, a cabinet for an energy storage cabinet is provided, including: a cabinet body 10 and a partition 20. The cabinet body 10 is provided with a first placement chamber 110 and a second placement chamber 120. The first placement chamber 110 and the second placement chamber 120 are separated by the partition 20.

[0026] The partition 20 includes a plurality of insulated box bodies 210 spliced ​​together in sequence. Each insulated box body 210 has an internal cavity, and each cavity is provided with an aluminum foil foam layer 220.

[0027] In this embodiment, the cabinet body 10 is internally divided into two independent chambers by a partition 20: a first placement chamber 110 and a second placement chamber 120. The partition 20 is composed of multiple interlocking insulation boxes 210. Each insulation box 210 has a cuboid structure with an internal cavity filled with an aluminum foil foam layer 220. Because the insulation boxes are interlocking, the length and shape of the partition 20 can be flexibly adjusted according to the size and requirements of the cabinet body 10. The interlocking structure makes the installation and disassembly of the partition 20 more convenient and reduces maintenance costs. For example, if it is necessary to add a new chamber or adjust the position of the partition 20, it is only necessary to simply add or reassemble the insulation box 210. Each insulation box 210 has an internal cavity filled with an aluminum foil foam layer 220. The aluminum foil foam layer 220 has good flexibility, which can better adapt to various complex shapes and structures inside the battery compartment of the energy storage cabinet, and can tightly fit the battery and other components, reducing gaps and improving the insulation effect.

[0028] It is worth mentioning that aluminum foil has excellent reflective properties, which can reflect heat and reduce heat conduction; the foam layer further blocks heat transfer. At the same time, the foam layer can absorb impact, protecting the energy storage components from external vibrations or impacts. The aluminum foil foam layer 220 is relatively lightweight, not increasing the weight of the cabinet body 10, while providing good thermal insulation and cushioning. It is also worth noting that the aluminum foil layer has a moisture-proof function, preventing moisture penetration that could degrade the foam's performance and thus affect the performance and lifespan of the energy storage components.

[0029] The aforementioned energy storage cabinet and its body have a partition 20 composed of multiple spliced ​​insulated boxes 210. Each insulated box 210 contains an aluminum foil foam layer 220. When the partition 20 is installed inside the cabinet body 10, the first placement chamber 110 and the second placement chamber 120 are isolated by the partition 20. The low thermal conductivity of the aluminum foil foam layer 220 and the air barrier effect of the cavity work together to suppress heat transfer, significantly improving the temperature stability of the battery compartment in extreme environments. When maintenance or replacement of a local insulation structure is required, only the corresponding insulated box 210 needs to be disassembled, without removing the entire partition 20, and it is adaptable to flexible layouts of chambers of different sizes. The aluminum foil foam layer 220 can prevent water vapor penetration, avoiding the problem of reduced insulation performance of traditional rock wool after it becomes damp. Through the above structure, while achieving efficient insulation, the technical defects of traditional energy storage cabinet partitions 20, such as large weight, complex installation, and easy failure in humid environments, are solved.

[0030] In one embodiment, such as Figure 1As shown, the partition 20 also includes an isolation support frame 230, which is connected to the cabinet body 10 and is disposed between the first placement chamber 110 and the second placement chamber 120. Each of the heat preservation boxes 210 is disposed on the isolation support frame 230, and adjacent heat preservation boxes 210 are connected through the isolation support frame 230.

[0031] In this embodiment, the partition 20 also includes an isolation support frame 230, which is connected to the cabinet body 10. Each insulated box 210 is mounted on the isolation support frame 230, which is connected to the cabinet body 10, ensuring that the partition 20 is firmly fixed inside the cabinet body 10 and will not shift due to external force or vibration. The isolation support frame 230 is positioned between the first placement chamber 110 and the second placement chamber 120, serving as a physical separator and further enhancing the isolation effect between the two chambers. Each insulated box 210 is mounted on the isolation support frame 230, and the structure of the isolation support frame 230 helps the insulated box 210 maintain its position and stability. Multiple insulated boxes 210 are sequentially spliced ​​on the isolation support frame 230, and adjacent insulated boxes 210 are connected by a support frame 241 to form an integral heat-insulating partition 20. The isolation support frame 230 can be connected to the cabinet body 10 by welding, bolting or other mechanical connection methods to ensure sufficient sturdiness, while facilitating disassembly and maintenance.

[0032] To further improve the stability of the insulation box 210 and prevent it from loosening or shifting, in another embodiment, such as... Figure 3 As shown, the isolation support frame 230 includes multiple crossbeams 231 and multiple longitudinal columns 232. Each crossbeam 231 and each longitudinal column 232 is connected to the cabinet body 10. Each crossbeam 231 and each longitudinal column 232 are staggered to form multiple mounting positions. Each heat preservation box 210 is set on one of the mounting positions.

[0033] In this embodiment, each crossbeam 231 and each longitudinal column 232 are connected at their intersections to form a grid-like frame structure. Adjacent crossbeams and longitudinal columns surround each other to form mounting positions for placing the insulation box 210. All crossbeams 231 and longitudinal columns 232 are directly or indirectly connected to the cabinet body 10, ensuring that the entire partition 20 system can be firmly fixed inside the energy storage cabinet. To further enhance stability, bolts, clips, or other types of fasteners 242 can be used to secure each insulation box 210 to the mounting position, preventing displacement or loosening of the insulation box 210 during transportation or use. The crossbeams 231 are lateral support components of the isolation support frame 230, connecting the two sides of the cabinet body 10 and providing lateral stability. The longitudinal columns 232 are longitudinal support components, connecting the front and rear (or top and bottom) of the cabinet body 10 and providing longitudinal stability.

[0034] In one embodiment, such as Figure 1 As shown, it also includes a bracket 240, which is fixed to the side of the isolation support frame 230 facing the first placement chamber 110.

[0035] In this embodiment, by installing a bracket 240 on the isolation support frame 230, additional support can be provided for the main equipment inside the energy storage cabinet, reducing the risk of damage to the equipment due to external impacts or vibrations. The bracket 240 can be made of high-strength materials, such as steel or aluminum alloy, to ensure sufficient load-bearing capacity and durability. The bracket 240 can be used to support and fix various electrical equipment or components, such as battery modules, distribution boxes, or other electronic components. The bracket 240 is fixed to the isolation support frame 230 by welding, bolting, or other mechanical connections, ensuring a secure connection while facilitating disassembly and maintenance. Furthermore, to improve corrosion resistance, the surface of the bracket 240 can be coated with an anti-corrosion coating or anodized.

[0036] In one embodiment, such as Figure 1 As shown, the bracket 240 includes a support frame 241 and a fastener 242, and the support frame 241 is fixed to the isolation support frame 230 by the fastener 242.

[0037] In this embodiment, to ensure the bracket 240 is securely fixed to the isolation support frame 230 and provides stable support for the energy storage element, the bracket 240 includes a support frame 241 and fasteners 242. The fasteners 242 securely fix the support frame 241 to the isolation support frame 230, ensuring the stability of the bracket 240 within the cabinet body 10, preventing loosening even under vibration or impact. To improve corrosion resistance and reduce friction, the surface of the support frame 241 can be coated, such as galvanized or painted. Notably, to connect the support frame 241 to the isolation support frame 230 after coating, the fasteners 242 can use bolts or screws to connect the support frame 241 to the isolation support frame 230. This connection method is robust, reliable, and easy to disassemble and maintain. The support frame 241 can be of different shapes, such as L-shaped, U-shaped, or frame-type.

[0038] In one embodiment, the fastener 242 is a screw. In this embodiment, the support frame 241 is provided with a threaded hole for engaging with the screw, and the isolation support frame 230 is provided with a corresponding mounting hole for engaging with the screw on the support frame 241. The mounting hole can be a circular hole or an elongated hole. To prevent the screw from loosening under vibration, an anti-loosening washer or thread-locking adhesive is provided on the screw.

[0039] In one embodiment, such as Figure 1 As shown, the bracket 240 also includes a limiting part 243, which is disposed at the first end of the support frame 241.

[0040] In this embodiment, the bracket 240 further includes a limiting part 243, which is located at the front end or side of the support frame 241 and is fixed to the support frame 241 by welding or integral molding. The limiting part 243 can be a baffle, a hook, or made of elastic material (such as rubber or spring), providing buffering and shock absorption functions while restricting the movement of the component. It is worth mentioning that the surface of the limiting part 243 is provided with rubber or elastic material to reduce the impact of collisions on the energy storage component and increase the friction between the limiting part 243 and the component surface, preventing the component from shifting.

[0041] To make the installation and maintenance of the insulation box 210 more convenient, reducing operational difficulty and time costs. In another embodiment, such as Figure 2 As shown, the heat preservation box 210 has a box opening that communicates with the cavity. The aluminum foil foam layer 220 is installed in the cavity through the box opening, and the opening is oriented towards the first placement chamber 110.

[0042] In this embodiment, the opening is an opening in the insulation box 210 that communicates with the internal cavity, used for installing and replacing the aluminum foil foam layer 220, making the installation and maintenance of the insulation material more convenient. The opening is oriented towards the first placement chamber 110; this orientation facilitates installation and maintenance operations.

[0043] In one embodiment, the material of the insulated box is sheet metal.

[0044] In one embodiment, an energy storage cabinet is provided, including the cabinet body, electrical unit, battery unit, and water-cooling unit described in any of the above embodiments. The battery unit is disposed in the first placement chamber 110, the water-cooling unit is disposed in the second placement chamber 120, and a third placement chamber 130 is also disposed inside the cabinet body 10. The third placement chamber 130 is disposed on one side of the second placement chamber 120, and the electrical unit is disposed in the third placement chamber 130.

[0045] 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.

[0046] 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 utility model patent. 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.
