Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a battery cabinet that facilitates the division of internal space. Background Technology

[0002] As the global energy structure shifts towards low-carbon development, lithium-ion battery energy storage systems are being deployed extensively in photovoltaic and wind power generation projects, as well as grid-side and user-side energy storage projects. As a key device housing battery modules and enabling energy storage and management, the performance of the battery cabinet directly impacts the safety and reliability of the energy storage system.

[0003] Existing battery cabinets generally suffer from the following problems: First, their internal space layout is fixed, making it difficult to flexibly adjust to the size and quantity requirements of different battery modules, resulting in poor equipment versatility and inability to adapt to diverse energy storage scenarios. Second, their heat dissipation design is unreasonable, making it difficult to effectively dissipate the heat generated by the batteries during charging and discharging, easily causing localized overheating, accelerating battery aging, and even leading to safety accidents such as thermal runaway. Third, their air filtration function is lacking or inefficient, allowing dust, moisture, and other impurities in the environment to easily enter the battery compartment, affecting not only the battery's heat dissipation efficiency but also potentially causing short circuits and corrosion of electrical components, thus shortening the battery cabinet's lifespan. Therefore, a battery cabinet with easily partitioned internal space is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by proposing a new type of battery cabinet with flexible space division, efficient heat dissipation and reliable protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery cabinet that facilitates the division of internal space, comprising a battery cabinet body, wherein a limiting rod is installed in a strip-shaped groove inside the battery cabinet body, and screw holes for mounting screws are evenly distributed on its surface; four battery-carrying frames are installed between the limiting rods by screws, which are used for battery installation and heat dissipation; battery modules are installed in the battery-carrying frames; a high-voltage control box for controlling the battery cabinet is installed at the bottom of the battery cabinet body; a filter ventilation window for filtering air in its battery compartment is installed in a rectangular through hole on one side of the battery cabinet body; a first cabinet door for closing its functional areas is installed on the battery cabinet body by hinges; a second cabinet door for closing its battery compartment and high-voltage compartment is installed on the battery cabinet body by hinges; an exhaust fan for exhausting air from the battery compartment of the battery cabinet body is installed in the through hole of the second cabinet door.

[0006] Preferably, the battery frame includes a battery base frame for mounting the battery module, which is installed between the limiting rods by screws, and a cooling fan installed in the through hole of the battery base frame for heat dissipation of the battery module.

[0007] Preferably, the cooling fan blows air from bottom to top, and the front and rear surfaces of the battery base frame are provided with strip-shaped through holes for exhausting air.

[0008] Preferably, the filter ventilation window includes an outer frame installed in a rectangular through hole on one side of the battery cabinet body, a rubber gasket pasted inside the outer frame for sealing, a rectangular filter sheet fitted onto a short post inside the outer frame through an edge through hole, and a limiting clip frame inserted into the outer frame and pressing down on the edge of the rectangular filter sheet.

[0009] Preferably, the limiting frame is locked by a spring plate in a rectangular groove that engages with a slot on the inner side of the window frame.

[0010] Preferably, the rectangular filter sheet consists of a filter screen and filter cotton, used to filter dust in the air.

[0011] The beneficial effects of this utility model are as follows: By incorporating a limiting rod, a battery-carrying frame, a filter ventilation window, and an exhaust fan, the performance of the battery cabinet is improved in terms of spatial division flexibility, heat dissipation efficiency, and air filtration. Specific beneficial effects are as follows:

[0012] Flexible internal space partitioning to adapt to different installation needs:

[0013] The limit rod surface is evenly distributed with screw holes, which can be used to install the battery frame in different positions, allowing for vertical adjustment and detachment. This enables flexible adjustment of the installation spacing and number of battery modules, meeting the installation requirements of battery modules of different specifications and improving the adaptability of the battery cabinet to different energy storage scenarios.

[0014] Build an efficient heat dissipation system to ensure stable battery operation:

[0015] The cooling fan inside the battery frame blows air upwards, pushing it into the battery compartment through the filter vent. After passing through the battery module for cooling, the air is discharged through the strip-shaped holes on the front and rear surfaces of the battery frame. Then, the exhaust fan expels the cooled air out of the battery cabinet, forming an air circulation channel from air intake through the filter vent, cooling fan blowing air, to exhaust fan exhaust. This enhances airflow, effectively removes the heat generated by the battery module during operation, prevents the battery from overheating and affecting its performance or causing safety hazards, and ensures the stable operation of the battery cabinet.

[0016] Filtering air impurities extends battery life:

[0017] The rectangular filter in the vent window consists of a filter screen and filter cotton, which can effectively filter dust and other impurities in the air entering the battery compartment, preventing dust from accumulating on the battery module and electrical components, affecting battery heat dissipation and performance. At the same time, it prevents dust and other impurities from causing wear or short circuits to the internal components of the battery cabinet, thus extending the service life of the battery cabinet.

[0018] This creates a closed heat dissipation channel, improving both heat dissipation and protection.

[0019] The second cabinet door, together with the exhaust fan, filter ventilation window, and cooling fan of the battery frame, forms a closed heat dissipation channel. While ensuring heat dissipation efficiency, it also isolates the battery compartment from the external environment, reducing the entry of external dust, moisture, and other impurities into the battery compartment, improving the protective performance of the battery cabinet, and providing a safer and more stable working environment for the battery modules.

[0036] The exhaust fan 9 is installed in the through hole of the second cabinet door 8 to exhaust the cooled air in the battery compartment. It works with the filter ventilation window 6 and the cooling fan 302 to form an air circulation, thereby enhancing the heat dissipation effect of the battery module 4.

[0037] See appendix Figure 1-4As shown, the battery frame 3 includes a battery base frame 301 installed between the limiting rods 2 by screws for mounting the battery module 4, and a cooling fan 302 installed in the through hole of the battery base frame 301 for heat dissipation of the battery module 4.

[0038] The cooling fan 302 blows air from bottom to top, and the front and rear surfaces of the battery base frame 301 are provided with strip-shaped through holes for exhausting air.

[0039] Specifically, the battery base frame 301 is installed between the limiting rods 2 by screws to fix the battery module 4. The front and rear surfaces are provided with strip-shaped through holes to form an air circulation channel with the cooling fan 302 to exhaust the cooled air. The cooling fan 302 is installed in the through holes of the battery base frame 301 and blows air from bottom to top, pushing the air in through the filter vent 6, flowing through the battery module 4 for cooling, and then exhausting through the strip-shaped through holes of the battery base frame 301.

[0040] See appendix Figure 1-7 As shown, the filter ventilation window 6 includes an outer frame 601 installed in a rectangular through hole on one side of the battery cabinet body 1, a rubber gasket 602 pasted inside the outer frame 601 for sealing, a rectangular filter 603 fitted onto a short post inside the outer frame 601 through an edge through hole, and a limiting clip frame 604 inserted into the outer frame 601 and pressing down the edge of the rectangular filter 603.

[0041] The limiting frame 604 is locked by a spring plate in a rectangular groove that is engaged in a slot on the inner side of the window frame 601.

[0042] The rectangular filter 603 consists of a filter screen and filter cotton, and is used to filter dust in the air.

[0043] Specifically, the outer frame 601 is installed in a rectangular through hole on one side of the battery cabinet body 1, serving as the frame for the filter ventilation window 6; the rubber gasket 602 is pasted inside the outer frame to provide a seal, preventing dust, moisture, and other impurities from entering the battery compartment through gaps; the rectangular filter 603, composed of a filter screen and filter cotton, is installed inside the outer frame 601 to filter dust from the air entering the battery compartment, ensuring clean air and preventing dust from affecting battery heat dissipation and performance; the limiting clip frame 604 is inserted into the outer frame 601, pressing down on the edge of the rectangular filter, and is locked in place by a spring clip in the groove on the inner side of the outer frame 601, fixing the rectangular filter 603 for easy disassembly and replacement.

[0044] The operation process of this utility model is as follows: When installing the battery frame 3 and the battery module 4, according to the number of battery modules 4 and the installation spacing requirements, the screws on the battery bottom frame 301 are aligned with the corresponding screw holes on the limiting rod 2.
