Technical Field
[0001] This invention relates to the field of energy storage cabinet design technology, and more specifically, to an industrial liquid-cooled energy storage cabinet that is easy to install. Background Technology
[0002] With the rapid development of renewable energy (such as wind and solar power) 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 mainly employ air cooling technology; however, under high power and long-term operating conditions, problems such as low heat dissipation efficiency, power degradation, and equipment damage exist. Therefore, developing a new and efficient energy storage technology 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 effect.
[0003] In existing technologies, the connection between battery modules and liquid cooling systems often requires complex piping layouts and installation steps. Due to the need to improve heat dissipation efficiency, individual coolant pipelines are usually connected to each 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. It is not conducive to rapid deployment and maintenance. Furthermore, each battery is paired with a separate liquid pump and thermal sensor, which undoubtedly increases production costs and maintenance costs.
[0004] Therefore, there is a particular need to design an easy-to-install industrial liquid-cooled energy storage cabinet to solve the above-mentioned technical problems. Summary of the Invention

The heat exchange assembly includes a fixing cylinder fixed to the side wall of the heat-conducting plate, and a guide tube... The hot plate contains a serpentine heat exchange tube. A liquid outlet pipe is fixedly installed inside the battery compartment with a fixed cylinder. The top of the liquid outlet pipe is connected to a horizontal pipe 1 via a conduit. The inner wall of the fixed cylinder is sealed with a sliding piston. One side of the piston is connected to a sliding rod, and the other side of the piston is connected to a spring 1 in the fixed cylinder. The sliding rod slides at the open end of the fixed cylinder and has an open design at its outer end. A top rod 1 is fixed to the inner wall of the open end. The sliding rod can be inserted into the liquid outlet pipe for sealing and sliding. The top rod 1 can be moved to contact a sealing plunger. The sealing plunger is located at the connection position between the liquid outlet pipe and the horizontal pipe 1 and is slidably installed inside the liquid outlet pipe. The sealing plunger is connected to a spring 2 in the liquid outlet pipe.
[0007] The lower part of the sliding rod opening is connected to the telescopic tube via a conduit. The conduit slides at the bottom opening of the sliding rod. The telescopic tube slides in a sealed manner outside the serpentine heat exchange tube, and the outlet end of the serpentine heat exchange tube is attached to the interface through which the top of the horizontal tube passes through the battery platform.
[0008] Preferably, one end of the second spring is fixedly connected to the circular plate, while the other end of the circular plate is connected to the alarm.

It also allows for flexible adjustment of the number of installed batteries, while avoiding the use of multiple liquid pumps. Based on the battery's heat generation, the coolant flow channel automatically opens to dissipate heat when the heat reaches the heat dissipation standard, thus making the equipment lower in cost and more convenient to use.
[0018] 2. This invention features a level gauge installed on the top of the liquid guide tank for real-time monitoring of the liquid level.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0037] like Figures 1-13 As shown, this invention discloses an easy-to-install industrial liquid-cooled energy storage cabinet. The cabinet body 1 has a partition plate 11 installed inside. A battery tray 12 is installed on one side of the partition plate 11, and a liquid guide tank 13 and a recovery tank 14 are installed on the other side. A horizontal pipe 131 on the lower side of the liquid guide tank 13 passes through the inside of the battery tray 12. A horizontal pipe 141 on the upper side of the recovery tank 14 connects to the bottom of the battery tray 12. Both the horizontal pipe 131 and the horizontal pipe 141 pass through the partition plate 11. A row of batteries 15 is installed on the top of the battery platform 12 to form a module. A heat-conducting plate 17 is fixed to the bottom of the battery 15. Horizontal tube 131 and horizontal tube 211 are connected to the heat-conducting plate 17 to form a heat exchange assembly 2. The heat exchange assembly 2 includes a fixing 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 extend out of the heat-conducting plate 17. The fixing cylinder 21 is fitted with a liquid outlet pipe 23 fixedly installed inside the battery platform 12. The top of the liquid outlet pipe 23 is open to the heat exchange assembly 2. A horizontal tube 131 is connected via a conduit. The inner wall of the fixed cylinder 21 seals the sliding piston. The space between the fixed cylinder 21 and the piston is filled with carbon dioxide at an appropriate pressure. One side of the piston is connected to the sliding rod 24, and the other side of the piston is connected to the fixed cylinder 21 and the spring 26. The sliding rod 24 slides at the open end of the fixed cylinder 21, and the outer end is designed with an opening. The inner wall of the opening is fixed with the top rod 27. The sliding rod 24 can be inserted into the liquid outlet pipe 23 for sealing and sliding. The top rod 27 can be moved to contact the sealing plunger 28. The sealing plunger 28 is located at the connection position between the liquid outlet pipe 23 and the horizontal tube 131 and is slidably installed inside the liquid outlet pipe 23. The sealing plunger 28 is connected to the liquid outlet pipe 23 and the spring 29. The lower part of the opening of the sliding rod 24 is connected to the telescopic tube 25 via a conduit. The conduit slides at the bottom opening of the sliding rod 24. The telescopic tube 25 slides and seals outside the serpentine heat exchange tube 22. The outlet end of the serpentine heat exchange tube 22 is attached to the interface of the top of the horizontal tube 141 that passes through the battery platform 12.
[0038] Through the above structural design, during assembly, the horizontal tube 131 is filled with coolant flowing down from the liquid guide tank 13 due to gravity, but cannot flow out because of the sealing plunger 28. Then, a row of batteries 15 is directly installed on top of the battery platform 12, and the fixing cylinder 21 on the bottom heat-conducting plate 17 of the battery 15 is tightly fitted with the outlet pipe 23. The sealing performance can be enhanced by a sealing gasket. The sliding rod 24 remains stationary at the open end of the fixing cylinder 21, and the push rod 27 extends into the outlet pipe 23 without contacting the sealing plunger 28, located to one side. The sealing plunger 28 springs... The spring 29 keeps the battery in a closed state, preventing coolant from flowing into the 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 from the heat-conducting plate 17 is transferred to the carbon dioxide inside the fixed cylinder 21, causing it to expand. The expanding carbon dioxide pushes the piston toward the opening end of the fixed cylinder 21, which in turn drives the sliding rod 24 to slide. As the sliding rod 24 moves, the push rod 27 gradually approaches and contacts the sealing plunger 28. The pressure applied by the push rod 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 coolant tank 13 enters the opening of the sliding rod 24 through the horizontal pipe 131, the conduit and the outlet pipe 23, and finally flows into the telescopic pipe 25 and into the serpentine heat exchange tube 22. In the serpentine heat exchange tube 22, the coolant exchanges heat with the heat generated by the battery 15. After absorbing heat, the temperature rises. The coolant after completing the heat exchange flows out from the outlet end of the serpentine heat exchange tube 22 and returns to the recovery tank 14 through the horizontal pipe 141. When the battery module stops working or the temperature drops, the temperature of the heat conduction plate 17 also decreases. As the cylinder descends, the carbon dioxide inside the fixed cylinder 21 cools and contracts, reducing pressure. At this time, spring 26 pushes the piston to move into the fixed cylinder 21, causing the sliding rod 24 to reset. The reset of the sliding rod 24 causes the top rod 27 to separate from the sealing plunger 28. Under the action of spring 29, the sealing plunger 28 closes the coolant passage again. 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 repeats continuously, pushing the sliding rod 24 to reciprocate, thereby realizing the circulation and guidance of coolant.
[0039] One end of spring 29 is fixedly connected to circular plate 211, while the other end of circular plate 211 is connected to alarm 212. The button of alarm 212 passes through circular plate 211 and corresponds to the position of push rod 210 on one side of sealing plunger 28.
[0040] Through the design of alarm 212 and push rod 210, when the battery is damaged and the temperature continues to rise, the cooling system cannot effectively cool the battery. The continuous temperature rise causes push rod 27 to continuously push the sealing plunger 28. Finally, push rod 210 contacts the button of alarm 212, triggering the alarm and prompting the staff to shut down 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 it is broken.
[0042] When the battery malfunctions, the temperature rises abnormally due to the glass cover 213. At the same time as the alarm 212 is triggered, the glass cover 213, made of a special material, can automatically break when it reaches a certain temperature, releasing carbon dioxide and thus preventing danger caused by excessive pressure inside the fixed cylinder 21. This is very practical.
[0043] Both sides of the sealing plunger 28 and the sliding rod 24 are provided with protrusions, and the protrusions slide in the corresponding slides inside the fixed cylinder 21 and the liquid outlet pipe 23.
[0044] The raised rib design increases stability and guidance during sliding, preventing the sealing plunger 28 and sliding rod 24 from shifting or jamming during sliding. At the same time, the raised rib also enhances structural strength, increasing the service life of the entire device.
[0045] A liquid level sensor 19 is installed on the top of the liquid guide tank 13, and a liquid pump 18 is installed on one side of the recovery tank 14. The output pipe of the liquid pump 18 is connected to the liquid guide tank 13.
[0046] A level sensor 19 is installed on the top of the liquid transfer tank 13 to monitor the liquid level in the tank in real time. When the liquid level reaches a preset threshold, the level sensor 19 sends a signal to trigger a corresponding operation (such as starting the liquid pump 18). The liquid pump 18 is installed on one side of the recovery tank 14, and its output pipe is connected to the liquid transfer tank 13 to extract the liquid from the tank and transport it to the recovery tank 14. This structure realizes automatic liquid recycling and reuse, improving resource utilization.
[0047] A slot seat 16 is installed on the top of the battery stand 12. Multiple batteries 15 are inserted into the slot seat 16 through the front opening and are attached to the slot wall. A row of heat sinks 112 is fixedly installed on the bottom of the heat conduction plate 17. The heat sinks 112 are inserted into the front opening of the battery stand 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 to blow air onto the heat sinks 112. The cabinet door of the cabinet 1 is provided with a corresponding air outlet. A metal plate 110 is provided on the front of the battery 15. The metal plate 110 is attached to the front of the slot seat 16 and fixed with screws.
[0048] A slot 16 is installed on the top of the battery tray 12. Multiple batteries 15 can be inserted through the front opening of the slot 16 and fit tightly against the slot wall. For effective heat dissipation, a row of heat sinks 112 is fixedly installed on the bottom of the heat conduction plate 17. These heat sinks 112 pass through the front opening of the battery tray 12, and the opening is located between the slots of the slot 16. A cooling fan 111 is installed on the back of the cabinet 1. The fan 111 blows air onto the heat sinks 112 to accelerate heat dissipation. The fan 111 is used for auxiliary heat dissipation and can be used with an existing thermometer. At the same time, the cabinet door of the cabinet 1 has a corresponding air outlet to ensure that heat is discharged smoothly. To further enhance the heat dissipation effect, a metal plate 110 is also provided on the front of the battery 15. The metal plate 110 is attached to the front of the slot 16 and fixed with screws to improve the heat conduction efficiency.
[0049] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
