[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8This invention discloses an energy storage cabinet, including a housing structure 1. An installation frame structure 2 is provided on the inner side of the housing structure 1, dividing the inner cavity of the housing structure 1 into a battery placement cavity 3 and a control equipment placement cavity 4. A cooling structure 5 is provided on the back side of the housing structure 1. The housing structure 1 includes a support frame 101, with a placement frame 102 at the bottom end of the support frame 101. A bottom protective plate 103 is provided at the bottom end of the placement frame 102. A base plate 104 is provided at the bottom of the inner side. A top protective plate 105 is provided at the top of the support frame 101. Four sets of connecting hanging rings 106 are provided at the top of the top of the top of the top of the top of the support frame 101. A top plate 107 is provided at the top of the inner side of the support frame 101. A left side plate 108 and a right side plate 109 are provided on both sides of the support frame 101, respectively. A protective back plate 110 is provided on the back of the support frame 101. The protective back plate 110 has mounting holes adapted to the heat dissipation device 501. By setting up the cooling structure 5, the heat dissipation device 501 can absorb the heat released by the battery module and control equipment during operation. In conjunction with the water tank device, the absorbed heat can be exchanged, causing the battery placement cavity and the control equipment placement cavity to form a cold cavity, thereby improving the heat dissipation effect of the energy storage cabinet, reducing the temperature inside the cabinet, ensuring that the battery can operate in the optimal temperature range, reducing the impact of heat on electronic components, and improving the service life of electronic components.

[0032] The installation frame structure 2 includes a fixed frame 201, with a partition strip 202 on the inner side of the fixed frame 201, and a placement clamping plate 203 and a connecting clamping plate 204 on the inner side of the fixed frame 201.

[0033] The fixed frame 201 is made of high-strength steel, ensuring the overall stability of the mounting frame structure 2. The partition strip 202 effectively isolates the battery placement cavity 3 and the control device placement cavity 4, preventing mutual interference between the battery module and the control device, and also facilitating separate management and maintenance of the two.

[0034] The cooling structure 5 includes a heat dissipation device 501 and a water tank device 502. The heat dissipation device 501 and the water tank device 502 are connected. The heat dissipation device 501 is located inside the cover structure 1, and the water tank device 502 is located outside the cover structure 1.

[0035] The heat dissipation device 501 includes a connecting frame 503. Two sets of heat-conducting fans 504 are provided on the front side of the connecting frame 503. Heat dissipation fins 505 are provided on the inner side of the connecting frame 503. Cooling coils 506 are inserted inside the heat dissipation fins 505. The inlet and outlet ends of the cooling coils 506 are respectively fixedly connected to a water inlet pipe 507 and a water outlet pipe 508.

[0036] The water tank device 502 includes a storage tank 509, the inner side of which is filled with coolant. A water outlet pump 510 and a water return pump 511 are fixedly installed on the front side of the storage tank 509. The water outlet pump 510 and the water return pump 511 are respectively connected to the water inlet pipe 507 and the water outlet pipe 508. A semiconductor cooling chip 516 is provided on the outer side of the storage tank 509. The cold end of the semiconductor cooling chip 516 extends to the inner side of the storage tank 509. A heat exchange fan 517 is provided on the hot end of the semiconductor cooling chip 516.

[0037] The cold end of the semiconductor cooling chip 516 is used to keep the coolant at a low temperature, so that the coolant can always maintain the heat exchange effect during the circulation process. The gap between the semiconductor cooling chip 516 and the protective back plate 110 can be sealed with hot melt adhesive or sealant.

[0038] After a period of use, the hot end of the thermoelectric cooler 516 will generate a certain amount of heat. If this heat is not dissipated, it will not only affect the thermoelectric cooler 516, but may also affect its cooling effect. The heat exchange fan 517 can dissipate the heat generated by the thermoelectric cooler 516, reduce the impact of heat on the thermoelectric cooler 516, and thus ensure the cooling effect of the thermoelectric cooler 516.

[0039] Specifically, the placement clamp 203 is used to place the battery mold, and the connecting clamp 204 is used to place the control device.

[0040] In this embodiment, both the placement clamp 203 and the connecting clamp 204 are made of high-strength insulating material, ensuring the safety and stability of the battery mold and control equipment during placement. Simultaneously, the surfaces of both the placement clamp 203 and the connecting clamp 204 are provided with anti-slip textures, increasing the friction between the battery mold and control equipment and the clamps, preventing slippage or detachment during transportation or use.

[0041] Specifically, a front door frame 205 is provided on the front side of the fixed frame 201, and a protective front door 206 is hinged to both sides of the front door frame 205. A rear door frame 207 is provided on the back side of the fixed frame 201, and a protective rear door 208 is hinged to the side end of the rear door frame 207.

[0042] In this embodiment, the design of the front door frame 205 and the protective front door 206 facilitates the installation, replacement, or maintenance of the battery module inside the battery placement cavity 3 by staff. Meanwhile, the protective front door 206 is hinged to the front door frame 205, ensuring its stability and ease of use during opening and closing.

[0043] The rear door frame 207 and the protective rear door 208 facilitate the inspection and maintenance of the control equipment inside the control equipment placement cavity 4 by the staff. Similar to the protective front door 206, the protective rear door 208 is also connected to the rear door frame 207 by a hinge, ensuring its stability and convenience during opening or closing.

[0044] Specifically, a connecting support rod 512 is fixedly installed on the front side of the storage box 509, and the other end of the connecting support rod 512 is movably engaged with the back side of the protective back plate 110.

[0045] In this implementation scheme, the design of the connecting strut 512 not only ensures the stability of the storage enclosure 509 but also provides it with flexible disassembly and assembly capabilities. When cleaning, repairing, or replacing the storage enclosure 509 is required, staff can easily release the latch between the connecting strut 512 and the protective backplate 110 to remove the storage enclosure 509 from the rack, greatly improving maintenance convenience. Furthermore, the material selection for the connecting strut 512 has been carefully considered to ensure it possesses sufficient strength to support the weight of the storage enclosure 509 while also exhibiting good corrosion resistance to withstand harsh environments such as humidity and dust that may exist inside the rack, thereby extending the service life of the connecting strut 512.

[0046] Specifically, the top of the storage box 509 is connected to a middle cover plate 513, and the front and rear ends of the middle cover plate 513 are hinged to side end cover plates 514. A locking pin 515 is provided at the opening of the storage box 509, and the locking pin 515 is movably engaged with the side end cover plate 514.

[0047] In this embodiment, the hinged design of the central cover 513 and the side end cover 514 allows personnel to easily open or close the top of the storage box 509 without removing it, thereby enabling coolant replenishment, inspection, or other necessary maintenance. The movable snap-fit ​​mechanism between the locking pin 515 and the side end cover 514 ensures the sealing of the storage box 509 when closed, preventing accidental coolant leakage during cabinet operation and also improving the overall safety of the cabinet.

[0048] During use, the heat-conducting fan 504 in the heat dissipation device 501 runs continuously, generating airflow to accelerate the airflow in the battery placement cavity 3 and the control device placement cavity 4, and carrying heat to the heat dissipation fins 505 for heat exchange.

[0049] The coolant in the storage tank 509 is pumped into the cooling coil 506 through the inlet pipe 507 by the outlet pump 510. The cooling coil 506 is arranged inside the heat dissipation fins 505, which increases the contact area with the heat dissipation fins 505 and improves the heat exchange efficiency.

[0050] As the coolant flows, it absorbs heat from the heat dissipation fins 505 and then flows back to the storage tank 509 through the outlet pipe 508.

[0051] At this time, the coolant is further cooled by the thermoelectric cooler 516 in the storage tank 509. The cold end of the thermoelectric cooler 516 continuously absorbs the heat of the coolant and releases the heat to the external environment through its hot end. The heat exchange fan 517 accelerates the flow of air around the hot end to help dissipate this heat.

[0052] This combination of active cooling and coolant circulation improves the heat dissipation efficiency of the energy storage cabinet, ensuring that the battery modules and control equipment operate at the optimal operating temperature, extending their service life, and reducing the risk of safety accidents caused by overheating.

[0053] In summary, this energy storage cabinet, by incorporating a cooling structure 5 and utilizing a heat dissipation device 501, can absorb the heat released by the battery modules and control equipment during operation. Furthermore, the water tank device 502 can exchange the absorbed heat, creating a cold cavity between the battery placement chamber 3 and the control equipment placement chamber 4. This improves the heat dissipation effect of the energy storage cabinet, reduces the internal temperature, ensures the battery operates within its optimal temperature range, minimizes the impact of heat on electronic components, and extends the lifespan of the electronic components.

[0054] It should be noted that the specific models and specifications of the heat conduction fan 504, water outlet pump 510, water return pump 511, semiconductor cooling chip 516, and heat exchange fan 517 in the energy storage cabinet need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0055] Furthermore, the power supply and operating principles of the heat-conducting fan 504, water pump 510, water return pump 511, semiconductor cooling chip 516, and heat exchange fan 517 in the energy storage cabinet are clear to those skilled in the art and will not be described in detail here.

[0056] Furthermore, the working principles and wiring methods of the heat conduction fan 504, water outlet pump 510, water return pump 511, semiconductor cooling chip 516, and heat exchange fan 517 in the energy storage cabinet are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
