[0002] A battery storage cabinet is a device used to store and release electrical energy. It typically consists of multiple batteries that can store electrical energy from the power grid or other power generation equipment for later use. One of the main functions of a battery storage cabinet is to regulate the supply and demand balance of the power system. Battery storage cabinets generate heat during prolonged use, thus requiring cooling to ensure the normal operation and lifespan of the batteries. Common cooling methods include air cooling and liquid cooling. Liquid cooling involves transferring a liquid coolant into the battery storage cabinet, where it circulates to absorb and carry away heat, providing highly efficient cooling.

In addition, the pipe connections between components have poor sealing and are prone to leakage, resulting in low disassembly and assembly efficiency. Furthermore, the pipes are easily pulled and damaged during the disassembly and installation of various components. Utility Model Content

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the first clamping mechanism 3 includes several compression springs 301. One end of each compression spring 301 is welded to the top and bottom walls of the grooves opened on the left and right sides of the first chamber 2. The upper and lower sets of compression springs 301 are provided with clamping plates A302 at their opposite ends. The upper and lower sets of clamping plates A302 clamp the cold plate 4 on their opposite sides.

[0023] In this embodiment, as Figure 2 As shown, the pump valve mechanism 7 includes a water pump 701, a water pump pipe 702 is inserted into the upper end of the water pump 701, and a water outlet pipe 703 is inserted into the bottom end of the water pump 701. The water pump pipe 702 and the water outlet pipe 703 respectively penetrate vertically through the top and bottom walls of the protective box 704. A valve 705 is installed on the outer wall of the water pump pipe 702. Both the water pump pipe 702 and the water outlet pipe 703 are connected to a telescopic hose 11.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the second clamping mechanism 6 includes two electric telescopic rods 601. The tail ends of the two electric telescopic rods 601 are screwed to the inner walls of the left and right sides of the second chamber 5. The driving ends of the two electric telescopic rods 601 are provided with clamping plates B602. The opposite sides of the clamping plates B602 are clamped to the outer walls of the left and right sides of the protective box 704.

[0025] In this embodiment, as Figure 1 and Figure 2 and Figure 4 As shown, the heat exchange mechanism 9 includes a heat exchange plate 901. The bottom end of the heat exchange plate 901 is provided with several sets of heat dissipation fins 902. The left and right sides of the heat exchange plate 901 are slidably connected to the inner walls of the left and right sides of the third chamber 8. The bottom end of the return pipe 12 is inserted into one side of the top of the heat exchange plate 901. The top end of the return pipe 12 is inserted into the water inlet end of the cold plate 4. The return pump 1201 is installed on the outer wall of the return pipe 12.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the heat dissipation mechanism 10 includes a wind box 1001, a fan 1002 is screwed to the middle of the bottom wall of the wind box 1001, an isolation net 1003 is provided at the top opening of the wind box 1001, and the left and right sides of the wind box 1001 are slidably connected to the left and right inner walls of the third chamber 8 located directly below the heat exchange mechanism 9, and the fan 1002 is directly opposite the heat dissipation fins 902.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the connecting card 13 is divided into a slot 1301 and an insert plate 1302, and magnetic pieces 1303 are provided at opposite ends of the slot 1301 and the insert plate 1302.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this easy-to-maintain energy storage liquid-cooled unit operates as follows:

[0029] First, the operator can align the telescopic hoses 11 at the ports of the pump valve mechanism 7 (702 for pumping and 703 for outlet) with the slots 1301 or insert plates 1302 at the ports of the telescopic hoses 11 of the cold plate 4 and the heat exchange mechanism 9, and make the slots 1301 and insert plates 1302 at each position engage with each other, so that the slots 1301 and insert plates 1302 form an adsorption connection through the magnetic absorbing piece 1303, ensuring that the cold plate 4, pump valve mechanism 7 and heat exchange mechanism 9 form a sealed connection. Then, the slots 1301 and insert plates 1302 at the top of the return pipe 12 and the water inlet end of the cold plate 4 are engaged and adsorbed to complete the fixed assembly between the return pipe 12 and the cold plate 4 and the heat exchange plate 901.

[0030] In actual use, the coolant inside the cold plate 4 absorbs heat from the battery, thus raising its internal temperature. Simultaneously, the operator can activate the water pump 701 via the control system, drawing coolant from the cold plate 4 through the connected water pipe 702. This coolant flows downwards along the flexible hose 11 connected to the outlet of the cold plate 4. After the flow rate is regulated by valve 705, the coolant is then transported downwards along the outlet pipe 703 and the flexible hose 11 connected to it to the flexible hose 11 at the inlet of the heat exchange plate 901, and continues to flow into the interior of the heat exchange plate 901. The heat is evenly distributed in the internal flow channels of the heat exchange plate 901. At this time, the heat is conducted through the heat exchange plate 901 to the heat dissipation fins 902 at its bottom. During this period, the fan 1002 is started, so that the air in the air box 1001 flows upward through the isolation net 1003, sweeps over the surface of the heat dissipation fins 902, and carries away the heat through forced convection. Then, the cooled coolant is collected in the heat exchange plate 901. At this time, the return pump 1201 is started simultaneously to provide power to draw the cooled liquid into the return pipe 12, and continues to push the coolant upward along the return pipe 12 to be transported back to the interior of the cold plate 4, forming a closed loop.

[0031] When maintenance is required, the operator can first disassemble the telescopic hose 11 between the cold plate 4, the pump valve mechanism 7, and the heat exchange mechanism 9, as well as the return pipe 12 between the cold plate 4 and the heat exchange mechanism 9. By disassembling the slot 1301 and the insert plate 1302 at the pipe connection, the two are released from the adsorption state. Then, the cold plate 4 is pulled horizontally outward, causing the upper and lower clamping plates A302 to move with the cold plate 4 and compress the spring 301 until the clamping plates A302 separate from the cold plate 4. The cold plate 4 is then removed from the first chamber 2, and then the control system controls the two sides of the electric... The telescopic rod 601 drives the clamping plate B602 to retract to its original position, thereby releasing the clamp on the protective box 704. Then, the entire pump valve mechanism 7 can be manually pulled out from the second chamber 5 in the horizontal direction to complete the disassembly. Finally, the heat exchange plate 901 can be pulled horizontally to disengage it along the inner wall groove of the third chamber 8. During this process, the heat dissipation fins 902 move out synchronously with the heat exchange plate 901, and at the same time, the fan box 1001 is slid horizontally to disengage it from the cabinet 1 along the corresponding groove. The fan 1002 then slides out of the third chamber 8 to achieve independent disassembly, which facilitates the maintenance of each independent structural unit.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
