[0002] With the rapid development of the energy storage industry, the market demands for energy storage systems are also increasing. Energy storage cabinets are devices used to store and release electrical energy, and have great industrial and commercial value. They are mostly used in photovoltaic power generation systems and wind power generation systems.

[0003] The internal structure of an energy storage cabinet contains multiple sets of energy storage batteries. To protect these batteries, existing energy storage cabinets often employ a shell-type structure. The batteries are bolted to the inside of the shell, with the interface located at the rear of the battery, making inspection and maintenance very inconvenient. Furthermore, to dissipate heat from the batteries, existing energy storage cabinets often have a fan cooling structure. Structurally, existing energy storage cabinets often use a single air duct structure. Due to the concentrated installation of the energy storage batteries, a single air duct makes it difficult to achieve sufficient airflow, resulting in poor heat dissipation. Therefore, a more convenient energy storage cabinet for inspection and maintenance is proposed. Utility Model Content

In order to isolate and protect the two adjacent energy storage batteries 3, a protective partition 10 is fixedly installed between the two adjacent energy storage batteries 3. The protective partition 10 can be a metal partition, which can longitudinally isolate the fire source when the energy storage battery 3 catches fire.

[0027] To lock and limit the installed energy storage battery 3, see attached... Figure 4 As shown, a limiting block 7 is fixedly provided at the front of the fitting protrusion. A limiting screw hole is opened through the middle of the limiting block 7. A limiting bolt 8 is installed inside the limiting screw hole. The end of the limiting bolt 8 passes through the limiting block 7 and is threaded to the inside of the screw hole provided on the side of the mounting rail 6.

[0028] To control the heat dissipation and charging / discharging operations of the equipment, a thermal management module 4 and an energy storage control module 5 are installed inside the energy storage cabinet 1. The energy storage control module 5 is used for controlling the charging and discharging operations of the equipment. The energy storage control module 5 integrates charging / discharging control circuitry and voltage stabilizing and protection components, as shown in the attached diagram. Figure 3 As shown, the energy storage control module 5 is fixedly installed on the inner side of the energy storage cabinet 1 by bolts. The rear of the energy storage cabinet 1 is provided with a cable interface 18, which is electrically connected to the input terminal of the energy storage control module 5. The front of the energy storage battery 3 is plugged into a terminal block 9, which is electrically connected to the output terminal of the energy storage control module 5 by wiring. Placing the terminal block 9 at the front of the energy storage battery 3 facilitates the plugging and unplugging of the interface.

[0029] To facilitate the opening and closing of the energy storage cabinet 1, a protective door 2 is provided at the front of the energy storage cabinet 1. The protective door 2 is hinged to the front opening side of the energy storage cabinet 1. To facilitate the opening and closing of the protective door 2, a handle 17 is fixedly installed on the side of the protective door 2. An external panel 16 is provided on the side of the protective door 2. During inspection and maintenance, the wiring terminal 9 can be inserted simply by opening the protective door 2, which has excellent maintenance convenience.

[0030] The energy storage cabinet 1 has an internal heat dissipation mechanism, which includes an air inlet seat 11, a cooling fan 12, and an air guide seat 13. The air inlet seat 11 is fixedly installed at the rear of the energy storage cabinet 1 with bolts. Multiple cooling fans 12 are provided, and each cooling fan 12 is fixedly installed inside the air inlet seat 11 with bolts. An air inlet is provided at the rear of the air inlet seat 11.

[0031] As attached Figure 5 As shown, the air guide seat 13 is fixedly installed inside the rear side of the energy storage cabinet 1 by bolts. The air guide seat 13 is connected to the front opening of the air inlet seat 11. The air guide seat 13 is located inside the energy storage cabinet 1 and is connected to the front of the air inlet seat 11. In order to perform air diversion, as shown in the attached figure... Figure 6 As shown, air outlets 14 are evenly arranged at the front of the air guide seat 13. The air outlets 14 are evenly spaced at the front of the air guide seat 13 and are directly opposite the ventilation gap. A multi-channel heat dissipation structure is adopted. The energy storage batteries 3 are supported and installed inside the energy storage cabinet 1 at intervals. Ventilation gaps are left between adjacent energy storage batteries 3. The airflow is dispersed through the multiple air outlets 14 on the upper part of the air guide seat 13. The air outlets 14 are directly opposite the ventilation gaps, so that the airflow can be concentrated and flow into the ventilation gaps between adjacent energy storage batteries 3. This can realize the directional flow of air and greatly improve the heat dissipation efficiency of the device. In order to facilitate the airflow, a heat dissipation groove 15 is opened through the middle of the protective door 2.

[0032] Working principle or structural principle: During operation, the energy storage battery 3 inside the energy storage cabinet 1 stores electricity. At the same time, the cooling fan 12 inside the air inlet seat 11 works to draw in external air and deliver it into the interior of the air guide seat 13. The air diverted by the air guide seat 13 is blown into the interior of the energy storage cabinet 1 through multiple air outlets 14. The air outlets 14 are directly opposite the ventilation gaps between the energy storage batteries 3, so that the airflow can be concentrated and flow into the ventilation gaps between adjacent energy storage batteries 3, which can realize the directional flow of air. The air carries the working heat of the energy storage battery 3 through the airflow, and then the air is discharged through the heat dissipation channel 15 on the upper part of the protective door 2, completing the heat dissipation cycle.

[0033] When performing maintenance on the energy storage cabinet 1, flip open the protective door 2, then activate the maintenance mode of the equipment by operating the panel on the upper part of the energy storage control module 5, and perform maintenance on the components inside the energy storage cabinet 1. When disassembling the energy storage battery 3, simply loosen and remove the limiting bolts 8 on the upper part of the limiting side blocks 7 on both sides of the energy storage battery 3 and the terminal block 9 at the front of the energy storage battery 3, then pull the energy storage battery 3 forward to remove it. Similarly, simply fit and tighten the bolts to complete the installation and reset of the energy storage battery 3.

[0034] In summary, this energy storage cabinet has a protective door 2 at the front of the cabinet body 1, and the energy storage batteries 3 are installed using a sliding and fitting method. The energy storage batteries 3 are installed and supported by side slots, making disassembly and assembly convenient. The connector 9 is located at the front of the energy storage batteries 3. During inspection and maintenance, only the protective door 2 needs to be opened to insert the connector 9, which has excellent maintenance convenience. In addition, a multi-air duct heat dissipation structure is adopted. The energy storage batteries 3 are supported and installed inside the energy storage cabinet body 1 at intervals, and ventilation gaps are left between adjacent energy storage batteries 3. The airflow is dispersed by multiple air outlets 14 on the upper part of the air guide seat 13. The air outlets 14 are directly facing the ventilation gaps, so that the airflow can be concentrated and flow into the ventilation gaps between adjacent energy storage batteries 3, which can realize the directional airflow and greatly improve the heat dissipation efficiency of the device.
