[0002] In current large-scale energy storage devices, the energy storage battery pack is usually composed of multiple battery units arranged in an array to improve the overall energy density and efficiency of the system. In order to ensure stable operation of the battery during work, heat dissipation becomes a key link. As a high-efficiency heat dissipation method, liquid cooling is gradually widely used in the heat dissipation system of energy storage batteries due to its superior heat exchange performance. The liquid cooling system effectively takes away the heat generated by the battery through the circulation of liquid medium, maintains the battery within a suitable temperature range, and thus improves the service life and performance of the battery.

[0003] However, the existing liquid cooling heat dissipation technology still has some significant deficiencies in practical application, mainly in the high cost of liquid cooling plates. Specifically, the current liquid cooling plates are usually installed at the bottom of the energy storage battery pack, which not only needs to bear the heat exchange function, but also needs to bear a certain structural load, which puts higher requirements on the material selection, thickness and structure design of the liquid cooling plate. Therefore, the manufacturing cost of high-performance liquid cooling plates is high, which increases the investment of the entire energy storage system. In addition, another common installation method is to sandwich the liquid cooling plate between the bracket and the battery, however, this design makes the liquid cooling plate directly contact with the bracket, causing the liquid cooling plate to have to absorb heat from the bracket, thereby significantly reducing its heat exchange efficiency. This unreasonable path of heat transfer not only affects the heat dissipation effect, but also may cause the overall performance of the energy storage system to decline.

[0004] In view of the above problems, it is particularly important to develop an energy storage battery mounting seat with detachable heat dissipation plates. CONTENT OF THE INVENTION

[0007] In some embodiments, the base plate is a hollow metal plate.

[0008] In some embodiments, the side fixing plate is installed on the side of the base plate, and the side fixing plate includes a base portion and an arc-shaped plate portion extending from the base portion.

[0009] In some embodiments, the backing plate is a non-metal plastic plate.

[0010] In some embodiments, the base plate has a hanging ear formed on the side surface for installation.

[0011] In some embodiments, the bottom surface of the base plate is provided with a plurality of reinforcing ribs.

[0012] Compared with the prior art, the application has at least one of the following advantages:

[0013] 1. Reducing production cost: by optimizing the installation structure of the liquid cooling plate, the requirements for the material and thickness of the liquid cooling plate are reduced, thereby effectively reducing the manufacturing cost.

[0025] Referring to the drawings Figure 1 and 2The embodiment provides a storage battery mounting seat with detachable heat dissipation plates, which is suitable for installation and use of various high-performance storage batteries. The technical scheme of the mounting seat is described in detail in combination with specific design, composition and working principle. It should be particularly pointed out that the technical details not described are common knowledge of those skilled in the art.

[0026] The storage battery mounting seat comprises a base plate 1, a backing plate 2, a water-cooling plate 3 and side fixing plates 4, and each component part forms a stable assembly relationship through precise design, and simultaneously has the characteristics of easy maintenance and high-efficiency heat dissipation. The base plate 1 is a hollow metal plate, and aluminum alloy material is selected, so that the base plate 1 has the characteristics of light weight and high strength, and a fire-retardant rubber layer is arranged at the bottom of the base plate 1, which effectively blocks heat conduction and enhances the fireproof performance of the equipment. A plurality of inverted T-shaped grooves 6 are arranged on the upper surface of the base plate 1, and the grooves are used for mounting the backing plate 2 and the water-cooling plate 3. The size of the groove of the inverted T-shaped groove 6 is accurately matched with the T-shaped part 7 at the bottom of the backing plate 2 and the water-cooling plate 3, so that the components can be firmly fixed after being inserted, and displacement caused by vibration or external force is avoided.

[0027] The backing plate 2 is made of a non-metal plastic plate, and the height direction size of the backing plate 2 is consistent with that of the base plate 1, so that the flatness of the battery mounting surface is ensured, and meanwhile, the material of the backing plate 2 is selected to be a high-molecular polymer with excellent insulation performance, so that necessary electrical insulation protection is provided for the storage battery. The T-shaped part 7 is arranged at the bottom of the backing plate 2, and stable cooperation with the inverted T-shaped groove 6 of the base plate 1 can be achieved through simple insertion operation. The backing plate 2 not only plays a supporting role, but also reduces resonance in operation through the material characteristics.

[0028] The water-cooling plate 3 is made of copper alloy material with high thermal conductivity, and at least one heat exchange channel 5 is arranged in the water-cooling plate 3. The inner wall of the heat exchange channel 5 is designed with staggered mesh-shaped micro grooves. The micro grooves realize the capillary conveying function of the cooling medium through optimized geometric design. When the cooling medium flows, the micro grooves make the cooling liquid uniformly distributed along the wall surface through capillary action and the viscous force of the fluid, and accelerate the heat transfer. The distribution density, depth and pitch of the micro grooves can be adjusted according to actual application needs.

[0029] The bottom of the water-cooling plate 3 is also provided with the T-shaped part 7, and stable connection can be realized after the T-shaped part 7 is inserted into the inverted T-shaped groove 6 of the base plate 1, and meanwhile, the detachable design facilitates daily maintenance and replacement. When the cooling medium enters the water-cooling plate 3 through the liquid inlet, the liquid can quickly cover the entire heat exchange channel 5 and flow uniformly under the capillary action of the micro grooves, so that the heat absorbed by the water-cooling plate 3 can be effectively taken away, and finally discharged from the outlet, to complete the heat dissipation cycle.

[0030] The side fixing plate 4 is installed on the side edge of the base plate 1, and is composed of a base and an arc-shaped plate extending from the base. The arc-shaped plate provides lateral protection for the battery assembly, achieving lateral support with certain deformation elasticity for the energy storage battery. At the same time, the side edge of the base plate 1 extends to form a hanging ear, which is used to quickly connect the battery mounting seat with other structures, and the design of the hanging ear can adapt to the installation needs of various equipment frames.

[0031] The bottom of the base plate 1 is provided with several reinforcing ribs, which further enhance the structural strength and carrying capacity of the base plate 1 through reasonable distribution of the reinforcing ribs. This design ensures that the mounting seat can withstand the weight of the battery assembly and the vibration generated during operation for a long time, and remains stable under extreme working conditions.

[0032] In actual operation, first, the T-shaped piece 7 of the backing plate 2 is aligned with the inverted T-shaped slot 6 of the base plate 1 and inserted, then the water-cooled plate 3 is installed in the same way to the designated position, ensuring that the two are tightly attached to the surface of the base plate 1. Then, the side fixing plate 4 is locked on the side edge of the base plate 1 using bolts, completing the assembly of the main structure of the mounting seat. During operation, the cooling medium enters from the inlet of the water-cooled plate 3, is evenly distributed along the heat exchange channel 5, and is quickly removed through the capillary action and turbulent flow enhancement design of the micro-groove. The entire cooling process is efficient and stable, ensuring the safe operation of the battery under high load conditions.

[0033] This design has shown significant advantages in practical application. For example, when the mounting seat is used for large energy storage battery modules, its efficient heat dissipation function can significantly prolong the service life of the battery, and its quick and easy disassembly design makes installation and maintenance more convenient. The combination of reinforcing ribs and fire-retardant rubber layer further improves the safety and durability of the equipment.

[0034] It should be noted that specific details not described in this embodiment, such as the type of cooling medium and the precise size calculation of the micro-groove, are common knowledge to those skilled in the art and do not constitute a technical obstacle to this invention. The technical solution of this embodiment fully embodies the comprehensive advantages of efficient heat dissipation, stable support and convenient maintenance through reasonable structural design and material selection, and is suitable for various demand scenarios of energy storage equipment.

[0035] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
