Description

Technical Field

[0001] This invention relates to the field of energy storage cabinet technology, and more specifically, to an integrated liquid-cooled energy storage cabinet. Background Technology

[0002] With the rapid development of energy storage technology, energy storage systems are being used more and more widely in power supply, renewable energy integration and distributed energy management. As an important component of energy storage systems, the design and performance of energy storage cabinets directly affect the efficiency, safety and reliability of the entire energy storage system.

[0003] Currently, distributed energy storage systems mainly consist of independent energy storage system cabinets and battery racks assembled in an outdoor enclosure. This results in a large volume and low integration. Distributed energy storage systems generally use air cooling, which makes it difficult to balance protection levels and temperature control, leading to high maintenance and operating costs. Furthermore, the separate configuration of energy storage converter cabinets and battery systems results in low integration. At the same time, existing outdoor energy storage cabinets are generally air-cooled or liquid-cooled plate devices, which have poor adaptability to different environments. The temperature difference between the various battery boxes inside the cabinet is large, making it difficult to ensure that the outdoor cabinet can charge and discharge in a suitable temperature environment under harsh conditions, leading to a decrease in cycle life.

By pulling the sliding part 8, the cover plate 7 is raised and separated from the battery carrier 6, which facilitates the maintenance, disassembly and installation of the energy storage battery 23. At the same time, the energy storage battery 23 is clamped and fixedly installed inside the battery carrier 6. The coolant flowing inside the battery carrier 6 and the cover plate 7 exchanges heat and cools the energy storage battery 23, effectively preventing excessive temperature difference between the energy storage batteries 23 and improving the service life of the energy storage battery 23.

[0034] Example 2, please refer to Figure 1-13 This embodiment two is an improvement on the first embodiment as follows: Specifically, several U-shaped plates 15 are uniformly and symmetrically fixed on the inner wall of the battery chamber 3 from top to bottom; the connecting plates 10 at both ends of the battery carrier 6 are slidably disposed between the two U-shaped plates 15; the ends of the two outermost storage boxes 9 are respectively provided with J-shaped coolant inlet pipes 16 and J-shaped coolant outlet pipes 17; several insertion holes 18 are uniformly opened on the inner wall of the battery chamber 3 to be inserted and matched with the corresponding J-shaped coolant inlet pipes 16 and J-shaped coolant outlet pipes 17; several fastening nuts 49 are screwed to the ends of the J-shaped coolant inlet pipes 16 and J-shaped coolant outlet pipes 17.

[0041] Under the elastic action of the tension spring 33, the cover plate 11 is pulled to close onto the surface of the storage box 9, thus sealing and fixing the energy storage battery 23. This keeps the energy storage battery 23 in a sealed and cooled environment, improving the heat exchange effect of the energy storage battery 23.

Each set of J-shaped coolant outlet pipes 17 is connected to the extension pipe 48 on the coolant inlet pipe 47 via a hose. At the same time, the ear tubes 43 on the J-shaped coolant inlet pipes 16 and J-shaped coolant outlet pipes 17 are connected to the two sets of branch pipes 44 at the ends of the two outermost cover plates 11 via hoses. By starting the liquid cooler 45, the coolant is circulated.

[0046] Working principle of this embodiment two: When maintenance and replacement of the energy storage battery 23 in the battery carrier 6 are required, firstly, turn off the main power switch inside the energy storage cabinet 1. Then, pull out the sliding member 8 corresponding to the corresponding battery carrier 6. That is, pull the handle 42 to drive the two sets of slip rings 37 to slide along the J-shaped coolant inlet pipe 16 and the J-shaped coolant outlet pipe 17 respectively. The corresponding return spring 39 is stretched, and the guide ball 32 slides from the inclined guide plate 40 onto the surface of the straight guide plate 41. During this process, the cover plate 7 is squeezed by the inclined guide plate 40 and rises, causing the cover plate 11 to separate from the corresponding storage box 9. Pull the handle 29 outward to make the energy storage battery 23 slide along the inner wall of the storage box 9. The corresponding compression spring 28 is compressed, and the positive terminal 24 and negative terminal 25 at the end of the energy storage battery 23 slide out of the corresponding insulating tube 19 respectively. They slide out of the corresponding positive terminal 24 and negative terminal 25 respectively, and the energy storage battery 3 can be removed.
