[0002] With the large-scale grid connection of renewable energy and the advancement of smart grid construction, electrochemical energy storage systems play a key role in peak shaving, frequency regulation, peak shaving and valley filling scenarios. Sodium-ion batteries, due to their abundant raw material reserves, low cost and excellent performance over a wide temperature range, have shown broad application prospects in the field of energy storage.

[0003] However, large-scale energy storage systems typically employ a high-density modular layout. The Joule heat and electrochemical reaction heat generated during continuous charging and discharging of the battery tend to accumulate inside the module. Existing heat dissipation structures are difficult to match the irregular heat source distribution characteristics of the wide-blade sodium battery, posing a safety hazard of heat runaway. At the same time, during long-term use, a large amount of dust tends to accumulate on the surface of the interception components. If this dust is not treated, it can easily affect the efficiency of heat dissipation for the equipment. To solve the above technical problems, we have designed a wide-blade sodium battery energy storage air-cooled heat dissipation structure. Utility Model Content

It solves the problem that the heat dissipation structure is difficult to match the irregular heat source distribution characteristics of the wide-blade sodium battery, which poses a safety hazard of heat runaway. At the same time, during long-term use, a large amount of dust easily accumulates on the surface of the interception components, which can easily affect the efficiency of heat dissipation from the device.

[0015] Please see Figures 1-6 A wide-blade sodium battery energy storage air-cooling structure includes an assembly base shell 1, a wide-blade battery pack 2 fixedly installed in the inner cavity of the assembly base shell 1, a reinforcing rib plate 4 fixedly connected to the bottom of the inner cavity of the assembly base shell 1, bottom shell side plates 5 movably installed on both sides of the assembly base shell 1, battery tabs 3 fixedly connected to the front side of the wide-blade battery pack 2, a front encapsulation plate 8 movably installed on the front side of the assembly base shell 1, a dustproof mesh 10 embedded in the front side of the front encapsulation plate 8, a guide frame 11 fixedly connected to the front side of the front encapsulation plate 8, a dust removal mechanism 12 provided in the inner cavity of the guide frame 11, and a top cover 13 movably installed on the top of the assembly base shell 1, with a top cover 13 having a top... The device includes an air blowing mechanism 14 and a dust removal mechanism 12, which includes a sliding hole 17 located on the front side of the front encapsulation plate 8. The air blowing mechanism 14 includes a connecting box 19, which is fixedly installed on the top of the top cover 13. The bottom of the top cover 13 has a groove 22. By setting a reinforcing rib plate 4, the stability of the wide-blade battery pack 2 can be increased. The device can be sealed by the cooperation of the bottom shell side plate 5 and the top cover 13, thereby increasing the protection of the device. By setting a dustproof net 10, external dust can be intercepted. By setting a sliding hole 17, the connecting plate 16 can be guided, thereby increasing the stability of the connecting plate 16 when moving.

[0016] Please see Figure 2 , Figure 3 and Figure 5 A cooling fan 9 is fixedly installed on the rear side of the front plate 8 via a bracket. Heat dissipation holes 6 are provided on the rear side of the mounting bottom shell 1 and the surface of the bottom shell side plate 5. By setting the heat dissipation holes 6, the equipment can be easily cooled.

[0017] Please see Figure 1 and Figure 2 EVA cotton strips 7 are fixedly connected to both the surface of the wide blade battery pack 2 and the inner cavity of the reinforcing rib plate 4. There are several EVA cotton strips 7. The nozzle tube 23 can be stored by setting the groove 22 so that the nozzle tube 23 can be blown.

[0018] Please see Figure 2 and Figure 6 There are several grooves 22, and temperature sensors 15 are installed through both sides of the top of the top cover 13. By setting the temperature sensors 15, the temperature inside the equipment can be monitored in real time.

[0019] Please see Figure 2 , Figure 3 and Figure 5 A connecting plate 16 is movably installed in the inner cavity of the guide frame 11. The rear side of the connecting plate 16 passes through the sliding hole 17 and extends to the rear side of the encapsulation front plate 8. Cleaning brush plates 18 are fixedly connected to both sides of the surface of the connecting plate 16. By setting the connecting plate 16, multiple cleaning brush plates 18 can be moved up and down at the same time.

[0020] Please see Figure 4 and Figure 6 A cooling plate 20 is installed through the top of the connection box 19, and a nozzle pipe 23 is fixedly installed in the inner cavity of the groove 22. By setting the cooling plate 20, the inside of the connection box 19 can be cooled, thereby accelerating the heat dissipation efficiency of the equipment.

[0021] Please see Figure 4 and Figure 6 Both sides of the connecting box 19 are connected to connecting pipes 21. The top of the nozzle pipe 23 extends into the inner cavity of the connecting box 19. The wide blade battery pack 2 is composed of multiple wide blade batteries. By setting the connecting pipes 21, it is convenient for the air supply equipment to deliver outside air into the equipment.

[0022] During use, the user installs the wide-blade battery pack 2 into the mounting base 1, and then fixes the reinforcing rib plate 4 with bolts. This reinforces the battery pack 2, increasing its stability. During installation, EVA cotton strips 7 cushion the battery pack 2, preventing collisions with the reinforcing rib plate 4 and absorbing expansion stress during discharge, preventing mechanical deformation from increasing contact thermal resistance. Simultaneously, during heat dissipation, the temperature sensor 15 monitors the internal temperature. If the internal temperature is too high, the user can control the cooling element 20 to adjust its position on the connecting box 1. Cooling is performed inside the device. At the same time, the user connects the connecting pipe 21 to the air supply equipment, so that the air supply equipment can deliver air to the connecting box 19. Then the connecting box 19 delivers air to the nozzle pipe 23, so that the nozzle pipe 23 can blow low-temperature air into the device, thereby accelerating the heat dissipation efficiency of the device. During heat dissipation, excess air is also discharged through the heat dissipation hole 6 to prevent excess air from remaining in the device. Moreover, when the cooling fan 9 is dissipating heat, the user can also pull the connecting plate 16 up and down, so that the connecting plate 16 can drive the cleaning brush plate 18 to move up and down, so that it can clean the surface of the dustproof net 10 to prevent excessive dust from adhering to the surface of the dustproof net 10.

[0023] In summary, this wide-blade sodium battery energy storage air-cooling structure, through the assembly of a bottom shell 1, wide-blade battery pack 2, battery tabs 3, reinforcing ribs 4, bottom shell side plate 5, heat dissipation holes 6, EVA cotton strips 7, encapsulation front plate 8, cooling fan 9, and dustproof mesh 10, solves the problem that the heat dissipation structure is difficult to match the irregular heat source distribution characteristics of the wide-blade sodium battery, which poses a safety hazard of heat runaway. At the same time, during long-term use, the surface of the interception components is prone to a large amount of dust accumulation, which can easily affect the efficiency of heat dissipation of the equipment.
