[0002] With the rapid development of renewable energy (such as wind and solar) and the continuous advancement of smart grid technology, energy storage, as a crucial bridge connecting energy production and consumption, is becoming increasingly important. Traditional energy storage devices primarily use air cooling technology. However, under high-power and long-term operating conditions, problems such as low heat dissipation efficiency, power drop, and equipment damage exist. Therefore, the development of new and efficient energy storage technologies has become a focus of industry attention. Liquid-cooled energy storage cabinets, as a leading example, are gradually becoming the mainstream choice in the market due to their efficient heat dissipation performance and stable energy storage.

[0003] In the existing technology, the connection between the battery module and the liquid cooling system often requires complex pipeline layout and installation steps. Due to the need to improve heat dissipation efficiency, most of the time, a separate coolant pipeline is connected to a single battery. This often requires the disassembly of a large number of components during maintenance, which not only increases the difficulty of maintenance, but also increases the maintenance cost, which is not conducive to rapid deployment and maintenance. In addition, each battery is paired with a separate liquid pump and thermal sensor, which undoubtedly increases the production cost and the maintenance cost is also high.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0037] like Figures 1-13 As shown, the present invention discloses an industrial liquid cooling energy storage cabinet that is easy to install, a cabinet body 1, a partition plate 11 is installed inside the cabinet body 1, a battery table 12 is installed on one side of the partition plate 11 and the cabinet body 1, and a liquid guide box 13 and a recovery box 14 are installed on the other side of the cabinet body 1, a horizontal pipe 131 on one side of the lower end of the liquid guide box 13 penetrates the inner side of the battery table 12, and a horizontal pipe 2 141 on one side of the upper end of the recovery box 14 connects to the bottom of the battery table 12, and the horizontal pipe 131 and the horizontal pipe 2 141 both pass through the partition plate 11, and the battery A row of batteries 15 are installed on the top of the platform 12 to form a module. The bottom of the battery 15 is fixed with a heat conducting plate 17. The transverse tube 131 and the transverse tube 2 141 are connected to the heat conducting plate 17 to form a heat exchange assembly 2. The heat exchange assembly 2 includes a fixed cylinder 21 fixed to the side wall of the heat conducting plate 17 and a serpentine heat exchange tube 22 inside the heat conducting plate 17. Both ends of the serpentine heat exchange tube 22 pass through the heat conducting plate 17. The fixed cylinder 21 is attached to the liquid outlet pipe 23 fixedly installed on the inner side of the battery platform 12. The top of the liquid outlet pipe 23 is connected to the heat conducting plate 17. The cross tube 131 is connected through a conduit, and the inner wall of the fixed tube 21 is sealed with a sliding piston. The space between the inside of the fixed tube 21 and the piston is filled with carbon dioxide of a suitable pressure. One side of the piston is docked with a sliding rod 24, and the other side of the piston is docked with a spring 26 at the fixed tube 21. The outer end of the sliding rod 24 slides at the open end of the fixed tube 21 and is divided into an open design, and a top rod 27 is fixed on the inner wall of the opening. The sliding rod 24 can be inserted into the liquid outlet pipe 23 for sealed sliding. The top rod 27 can contact the sealing plunger 28 by movement. The sealing plunger 28 is located at the connection position between the liquid outlet pipe 23 and the cross tube 131, and is slidably installed inside the liquid outlet pipe 23, and the sealing plunger 28 is docked with the spring 29 of the liquid outlet pipe 23. The bottom of the opening part of the sliding rod 24 is docked with the telescopic tube 25 through the conduit, and the conduit slides at the bottom opening of the sliding rod 24. The telescopic tube 25 slides sealed on the outside of the serpentine heat exchange tube 22, and the outlet end of the serpentine heat exchange tube 22 fits the top of the cross tube 2 141 and passes through the docking port of the battery station 12.

[0038] With the above structural design, during assembly, the cross tube 131 is filled with coolant flowing down from the liquid guide box 13 due to gravity, but cannot flow out because of the blocking of the sealing plunger 28. Then a row of batteries 15 are directly mounted on the top of the battery table 12, and the fixed cylinder 21 on the heat conducting plate 17 at the bottom of the battery 15 fits tightly with the liquid outlet pipe 23. The sealing gasket can be used to enhance the sealing performance, and the sliding rod 24 remains stationary at the open end of the fixed cylinder 21. The top rod 27 extends into the interior of the liquid outlet pipe 23 and does not contact the sealing plunger 28. It is located on one side of it. The sealing plunger 28 is elastic. The spring 29 keeps the closed state, preventing the coolant from flowing into the liquid outlet pipe 23. When the battery module is working, the battery 15 generates heat, causing the temperature of the heat conducting plate 17 to rise. The heat of the heat conducting plate 17 is transferred to the carbon dioxide inside the fixed cylinder 21, causing it to expand due to heat. The expanded carbon dioxide pushes the piston to move toward the open end of the fixed cylinder 21, thereby driving the sliding rod 24 to slide. As the sliding rod 24 moves, the push rod 1 27 gradually approaches and contacts the sealing plunger 28. The pressure exerted by the push rod 1 27 overcomes the resistance of the spring 29, pushing the sealing plunger 28. Slide and open the coolant channel. At this time, the coolant in the liquid guide box 13 passes through the horizontal pipe 131, the conduit and the liquid outlet pipe 23, enters the opening of the sliding rod 24, and finally flows into the telescopic pipe 25 and enters the serpentine heat exchange tube 22. The coolant exchanges heat with the heat generated by the battery 15 in the serpentine heat exchange tube 22. After absorbing heat, the temperature rises. After completing the heat exchange, the coolant flows out from the outlet end of the serpentine heat exchange tube 22 and returns to the recovery box 14 through the telescopic pipe 25. When the battery module stops working or the temperature drops, the temperature of the heat conducting plate 17 also decreases. As the temperature of the heat conducting plate 17 rises and falls, the carbon dioxide inside the fixed cylinder 21 contracts due to the cold, and the pressure decreases. At this time, the spring 1 26 pushes the piston to move toward the inside of the fixed cylinder 21, driving the sliding rod 24 to reset. The reset of the sliding rod 24 separates the push rod 1 27 from the sealing plunger 28. The sealing plunger 28 closes the coolant channel again under the action of the spring 2 29. As the battery module works and rests, the temperature of the heat conducting plate 17 rises and falls continuously, causing the carbon dioxide to expand and contract. This process is repeated continuously, pushing the sliding rod 24 to perform reciprocating motion, thereby realizing the circulation and diversion of the coolant.

[0039] One end of the second spring 29 is fixedly docked with the circular plate 211 , and the other end of the circular plate 211 is docked with the alarm 212 . The button of the alarm 212 passes through the circular plate 211 and corresponds to the position of the second push rod 210 on one side of the sealing plunger 28 .

[0040] Through the design of the alarm 212 and the second push rod 210, when the battery is damaged and the temperature continues to rise, the cooling system cannot effectively cool the battery. The continued temperature rise causes the first push rod 27 to continuously push the sealing plunger 28. Eventually, the second push rod 210 contacts the button of the alarm 212, triggering the alarm and prompting the staff to close the energy storage cabinet for inspection.

[0041] A glass cover 213 is installed at the top opening of the fixed cylinder 21. The glass cover 213 is used to discharge the gas inside the fixed cylinder 21 after being broken.

[0042] When the battery fails, the temperature will rise abnormally through the glass cover 213. At the same time as the alarm 212 is triggered, the glass cover 213 is made of special material and can automatically break when a certain temperature is reached, releasing carbon dioxide, thereby avoiding danger caused by excessive pressure inside the fixed cylinder 21. It is very practical.

[0043] Both sides of the sealing plunger 28 and the sliding rod 24 are provided with convex strips, and the convex strips slide in corresponding slideways inside the fixed cylinder 21 and the liquid outlet pipe 23.

[0044] The design of the ridges increases the stability and guidance during the sliding process, preventing the sealing plunger 28 and the sliding rod 24 from deflecting or getting stuck during the sliding process. At the same time, the ridges also serve to enhance the structural strength and increase the service life of the entire device.

[0045] A liquid level gauge 19 is installed on the top of the liquid guiding box 13 , and a liquid pump 18 is installed on one side of the recovery box 14 . The output pipe of the liquid pump 18 is connected to the liquid guiding box 13 .

[0046] A level gauge 19 is mounted on top of the liquid-guiding tank 13 to monitor the liquid level within the tank in real time. When the liquid level reaches a preset threshold, the level gauge 19 sends a signal to trigger a corresponding operation (such as activating the liquid pump 18). The liquid pump 18 is mounted on one side of the recovery tank 14, and its output pipe connects to the liquid-guiding tank 13 to pump the liquid out of the tank and transfer it to the recovery tank 14. This structure enables automatic liquid recovery and reuse, improving resource utilization.

[0047] A slot seat 16 is installed on the top of the battery platform 12, and multiple batteries 15 are inserted from the front opening of the slot seat 16 and fit into the slot wall. A row of heat sinks 112 are fixedly installed at the bottom of the heat conducting plate 17. The heat sinks 112 pass through the front opening of the battery platform 12, and the opening is located between the slots of the slot seat 16. A cooling fan 111 is installed on the back of the cabinet 1 for blowing air towards the heat sink 112. Corresponding air outlets are provided on the cabinet door of the cabinet 1. A metal sheet 110 is provided on the front of the battery 15, and the metal sheet 110 fits into the front of the slot seat 16 and is fixed with screws.

[0048] A slot seat 16 is installed on the top of the battery platform 12. Multiple batteries 15 can be inserted from the front opening of the slot seat 16 and fit tightly against the slot wall. In order to effectively dissipate heat, a row of heat sinks 112 are fixedly installed at the bottom of the heat conducting plate 17. These heat sinks 112 pass through the front opening of the battery platform 12, and the opening is located between the slots of the slot seat 16. A cooling fan 111 is installed on the back of the cabinet 1. The fan 111 blows air towards the heat sink 112 to accelerate the dissipation of heat. The fan 111 is used as an auxiliary heat dissipation and can be used with an existing thermometer. At the same time, a corresponding air outlet is provided on the door of the cabinet 1 to ensure the smooth discharge of heat. In order to further enhance the heat dissipation effect, a metal sheet 110 is also provided on the front of the battery 15. The metal sheet 110 fits against the front of the slot seat 16 and is fixed with screws to improve the heat conduction efficiency.

[0049] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention.
