Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a novel large-capacity lead-acid battery combination structure. Background Technology

[0002] Currently, the rapid development of the communications and energy storage industries is leading to increasingly higher requirements for battery capacity and lifespan, resulting in larger battery sizes. To meet specific customer needs and installation environments, batteries are often installed horizontally. Compared to vertical installation, horizontal installation saves space and is more convenient for certain situations.

[0003] Lead-acid batteries require a certain distance between them during installation and use to facilitate ventilation and heat dissipation. However, in actual installations, the battery spacing often fails to meet these requirements, which can negatively impact battery performance. On-site investigations reveal that conventional single-cell installations are inconvenient. Excessive spacing makes wiring difficult, while insufficient spacing hinders ventilation and heat dissipation, causing a rapid increase in internal battery temperature, accelerating aging, shortening battery life, and potentially leading to safety hazards such as battery bulging and leakage. Furthermore, the installation process increases the risk of battery collisions and potential injuries. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a novel high-capacity lead-acid battery combination structure, the specific technical solution of which is as follows:

[0005] A novel high-capacity lead-acid battery assembly structure includes an assembly housing with an open upper part and a sealed lower part. The housing has at least one set of partitions that divide the interior cavity of the assembly housing into multiple accommodating spaces capable of holding lead-acid batteries. Each partition includes at least two parallel partitions with multiple heat dissipation holes evenly distributed on them. A gap is left between adjacent partitions. When the lead-acid battery is placed in the accommodating space, some of the heat from the side of the lead-acid battery can be conducted through the heat dissipation holes to the gap for dissipation.

[0006] As an improvement to the above technical solution: the upper and lower parts of the combined housing are provided with fixing parts, the fixing parts include two fixing blocks installed facing each other on the side of the combined housing, the extending direction of the fixing blocks is consistent with the axial direction of the combined housing, and the multiple fixing blocks maintain a safe distance between the multiple combined housings.

[0007] As an improvement to the above technical solution: the fixing block is detachably mounted with a pressure strip on the top of the upper part of the combined housing. When the lead-acid battery is placed into the receiving space, the pressure strip is installed on the fixing block to press the upper part of the lead-acid battery and prevent the lead-acid battery from sliding out.

[0008] As an improvement to the above technical solution: the extension direction of the pressure strip is consistent with the extension direction of the fixing block, and the pressure strip is fixedly installed on the fixing block by bolts.

[0009] As an improvement to the above technical solution: the side wall of the combined housing is provided with multiple heat dissipation holes to dissipate heat from the lead-acid battery placed in the housing space.

[0010] The beneficial effects of this utility model are:

[0011] 1. The application proposes to incorporate heat dissipation holes (one on the separator) and reserved spacing between adjacent separators, combined with heat dissipation holes (two on the side wall of the casing). During battery operation, heat can be rapidly conducted from the battery side through heat dissipation holes (one) to the spacing, and further diffused through air convection. Simultaneously, the side wall heat dissipation holes (two) promote heat exchange between the battery and the external environment. Compared to traditional single-cell installation methods, this significantly improves heat dissipation, effectively reduces the internal temperature of the battery, slows down battery aging, significantly extends battery life, reduces battery failures and replacement frequency due to overheating, and lowers operating costs.

[0012] 2. The combined structure integrates two batteries into a single housing, achieving stable installation and fixation through fixing blocks and pressure strips. The fixing blocks, positioned at the top and bottom of the housing, ensure a reasonable spacing between the assemblies, facilitating quick positioning and placement by operators during installation, improving installation efficiency, and preventing collisions between batteries. The pressure strips, bolted to the fixing blocks, apply reliable pressure to the upper part of the batteries, effectively preventing slippage during use and ensuring the batteries remain in the correct position. Even under equipment vibration or handling conditions, the battery connection remains stable, reducing issues such as loose wiring due to battery displacement and improving the overall reliability of the battery pack.

[0013] 3. It is suitable for horizontal installation of large-capacity batteries. While meeting ventilation, heat dissipation, and safety distance requirements, this combined structure is more compact than the dispersed installation of individual batteries, effectively saving installation space. In space-constrained locations such as communication base stations and energy storage power stations, it allows for more rational layout of battery packs, improving space utilization. Its standardized combined design also facilitates compatibility with different battery racks and equipment, enhancing application flexibility.

[0014] 4. The combined effect of excellent heat dissipation and stable installation ensures more stable battery performance during operation. The batteries can operate continuously and efficiently within a suitable temperature environment, reducing the impact of temperature fluctuations and battery displacement on battery performance and guaranteeing the stability of the battery pack's output power and capacity. Simultaneously, by avoiding safety hazards such as battery collisions and loose wiring, the safety of the battery pack is improved, reducing the risk of accidents such as fires and short circuits, providing strong protection for the safe and stable operation of communication and energy storage systems.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example

[0021] A novel high-capacity lead-acid battery combination structure is described below. Figures 1-3 The housing 1 is open at the top and closed at the bottom, with at least one set of partitions inside. Each partition consists of at least two parallel partitions 2, which evenly divide the interior of the housing 1 into multiple accommodating spaces 100 for lead-acid batteries. Multiple heat dissipation holes 21 are carefully designed on the partitions 2, with a certain distance 200 maintained between adjacent partitions 2. During battery operation, heat generated on the side of the battery can be conducted through the heat dissipation holes 21 to the space between them 200, forming a preliminary heat dissipation channel, effectively reducing the local temperature of the battery and ensuring stable battery performance.

[0022] In an optional embodiment, to ensure the stability of the combined structure during installation and use, both the upper and lower parts of the housing 1 are equipped with fixing parts. The fixing parts consist of two fixing blocks 3 mounted facing each other on the sides of the housing 1, extending in the same direction as the axial direction of the housing 1. When multiple assemblies are installed on the battery rack, the fixing blocks 3 cooperate with each other to precisely maintain a safe distance between the assemblies, preventing battery damage or circuit failure due to accidental collisions or displacement. Simultaneously, the fixing blocks 3 provide stable support for the assemblies, ensuring they maintain a stable position under different operating conditions and preventing shaking due to vibration or external interference.

[0023] In an optional embodiment, a removable pressure strip 4 is provided at the top of the fixing block 3, located on the upper part of the housing 1. The pressure strip 4 extends in the same direction as the fixing block 3 and is securely installed on the fixing block 3 by bolts. After the lead-acid battery is successfully placed into the receiving space 100, the installation pressure strip 4 can apply uniform pressure to the upper part of the battery, firmly fixing the battery in the assembly, effectively preventing the battery from slipping out due to various factors such as vibration and handling during use, further enhancing the reliability and safety of battery installation.

[0024] In an optional embodiment, in addition to the heat dissipation structure formed by the heat dissipation holes 21 and the spacing 200 on the separator 2, the sidewall of the housing 1 is also provided with multiple heat dissipation holes 5. These heat dissipation holes 5 further increase the heat exchange area between the battery and the external environment, forming a multi-dimensional heat dissipation path. When the battery generates heat during operation, the heat can not only be dissipated through the heat dissipation structure of the separator 2, but also quickly diffuse into the surrounding environment through the heat dissipation holes 5 on the sidewall, significantly improving the heat dissipation efficiency of the entire assembly structure, ensuring that the battery is always within a suitable operating temperature range, greatly extending the battery's service life, and improving the overall performance and reliability of the battery pack.

[0025] Specifically, in actual operation, after the lead-acid battery is placed in the housing space 100 and begins to work, the heat generated by the internal chemical reaction of the battery will gradually be transferred to the surroundings. Since the side of the battery is in close contact with the separator 2, the heat is first conducted to the separator 2. The heat dissipation holes 21 on the separator 2 provide a channel for heat dissipation, and the heat enters the gap 200 between adjacent separators 2 through these small holes. The air within the gap 200 heats up under the influence of the heat, forming natural convection, further diffusing the heat to the surroundings. For example, in high-temperature environments or when the battery is under high load, a large amount of heat will quickly enter the gap 200 through the heat dissipation holes 21. At this time, the air convection speed within the gap 200 increases, acting like a small heat dissipation duct, effectively carrying away the heat and preventing heat accumulation in localized areas of the battery, thereby maintaining the normal operating temperature of the battery and ensuring stable battery performance.

[0026] During installation, the fixing block 3 plays a crucial role when placing the assembly on the battery rack. The fixing block 3 is designed to fit snugly against the housing 1, and its extension direction is aligned with the axis of the housing 1, ensuring the horizontal stability of the assembly. When multiple assemblies are arranged sequentially on the battery rack, a specific spacing is maintained between the fixing blocks 3 of adjacent assemblies. This spacing not only prevents collisions between assemblies, avoiding potential battery damage or short circuits caused by collisions, but also ensures smooth airflow between the batteries. The airflow within the channels between the fixing blocks 3 creates excellent ventilation, helping to dissipate the heat generated by the batteries during operation, achieving the dual functions of fixing and heat dissipation. For example, in the installation of battery packs in large-scale energy storage power stations, a large number of assemblies are neatly arranged on the battery rack using the fixing blocks 3. The fixing blocks 3 ensure that each assembly is in a stable position, effectively maintaining the overall structural integrity and stability of the battery pack even during vibrations or external impacts during equipment operation.

[0027] After the lead-acid battery is successfully placed into the receiving space 100, a pressure strip 4 is installed to secure the battery. The pressure strip 4 is tightly bolted to the fixing block 3, with a portion positioned above the battery, applying uniform pressure. During equipment operation, various vibrations or slight displacements may occur; in these situations, the pressure strip 4 becomes crucial. It effectively restricts battery movement within the assembly, preventing collisions with the separator 2 or casing 1 due to vibration, thus avoiding damage to the battery casing or loosening of the internal structure. Simultaneously, the pressure strip 4 ensures the stability of the battery's electrode connections, preventing loosening of wiring due to battery displacement and guaranteeing the reliability of the battery pack's electrical connections. For example, during transportation, vehicle bumps may cause significant battery vibration, but due to the pressure of the pressure strip 4, the battery remains in the correct position, ensuring safety and battery integrity during transport.

[0028] Furthermore, the heat dissipation holes 5 on the side wall of the casing 1 work in conjunction with the heat dissipation structure of the separator 2 to jointly enhance the heat dissipation performance of the combined structure. When the air around the battery heats up due to absorbing heat from the battery, the hot air is exhausted to the outside environment through the heat dissipation holes 5. At the same time, cool air from the outside enters the casing 1 through these heat dissipation holes 5, forming a natural air circulation. This air circulation further enhances the heat dissipation effect and accelerates heat dissipation. For example, in a well-ventilated installation environment, cool air from the outside can continuously enter through the heat dissipation holes 5 and exchange heat with the heat dissipation structure of the separator 2, keeping the temperature around the battery at a low level, effectively extending the battery's lifespan and improving the overall reliability and stability of the battery pack.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
