[0045] The applicant discovered that the pipe system in the energy storage system is usually designed as a separate unit and then assembled. However, this method has many connection points, a high risk of leakage in the pipe system, and occupies a large space in the energy storage system.

[0046] In view of this, embodiments of this application provide a pipe structure that solves at least part of the above-mentioned technical problems by providing independent inlet and outlet chambers on a first pipe and a second pipe.

[0047] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This illustration shows a structural diagram of an energy storage system provided in an embodiment of this application; Figure 2 This illustration shows a cross-sectional view of the first pipe in the pipe system provided in an embodiment of this application; Figure 3 This illustration shows a cross-sectional view of the second pipe in the pipe system provided in an embodiment of this application. This application provides a pipe system for use in an energy storage system; the pipe system includes: a first pipe 10 and a second pipe 20, the first pipe 10 having a first inlet chamber 11 and a first outlet chamber 12 independently arranged; the second pipe 20 having a second inlet chamber 21 and a second outlet chamber 22 independently arranged; wherein, the first inlet chamber 11 of the first pipe 10 is connected to the second inlet chamber 21 of the second pipe 20, and the first outlet chamber 12 of the first pipe 10 is connected to the second outlet chamber 22 of the second pipe 20. Thus, by configuring the first pipe body 10 with independent first inlet chamber 11 and first outlet chamber 12, and configuring the second pipe body 20 with independent second inlet chamber 21 and second outlet chamber 22, and then directly connecting the first inlet chamber 11 of the first pipe body 10 to the second inlet chamber 21 of the second pipe body 20, and directly connecting the first outlet chamber 12 of the first pipe body 10 to the second outlet chamber 22 of the second pipe body 20, the number of connection points in the pipe system is greatly reduced, thus lowering the possibility of leakage due to numerous connection points. At the same time, a more direct and simple connection structure is formed, reducing the space occupied by the pipe system, making the connection of the pipe system more stable, and reducing the risk of leakage due to loose or unstable connections.

[0048] To improve the ease and flexibility of pipe system installation, in some embodiments, the first pipe 10 and the second pipe 20 are detachably connected. During the initial installation of the pipe system, the detachable connection allows the first pipe 10 and the second pipe 20 to be independently positioned and initially fixed before being accurately connected. This allows for greater flexibility in handling different installation environments and space constraints, improving installation convenience and efficiency, especially in situations with limited space or complex layouts.

[0049] Therefore, the detachable connection between the first tube 10 and the second tube 20 can use a quick-connect structure with a plug-and-play self-locking connection. The quick-connect structure can be a separate structure, specifically including a plug, a socket, a locking mechanism, and a seal. The plug and socket are installed separately; for example, the plug is installed at the end of the first tube 10 and the socket at the end of the second tube 20, or the plug is installed at the end of the second tube 20 and the socket at the end of the first tube 10. Then, the plug and socket are aligned and inserted, and seals are provided at the connection points of the plug and socket, the plug and tube, and the socket and tube. Finally, the locking mechanism locks the connection between the plug and socket. The quick-connect structure can also be an integral structure, with seals at both ends. After the first tube 10 and the second tube 20 are inserted into the ends of the quick-connect structure, they are sealed by the seals and then secured by the locking mechanism built into the quick-connect structure or an additional locking mechanism.

[0050] Understandably, other detachable connection methods can be selected based on the usage scenarios of the first pipe body 10 and the second pipe body 20. For example, threaded connections, flange connections, and clamp connections can be used. These methods can meet the detachable connection requirements between the first pipe body 10 and the second pipe body 20 while maintaining a sealed connection, thus improving the ease and flexibility of pipe system installation.

[0051] Please refer to it again. Figure 3In some embodiments, the pipe system is used for an energy storage system. The pipe system further includes at least two third pipes 30 and at least two fourth pipes 40. The two ends of the third pipes 30 are respectively connected to the second inlet chamber 21 and the energy storage unit 80 of the energy storage system; the two ends of the fourth pipes 40 are respectively connected to the second outlet chamber 22 and the energy storage unit 80. During operation, the energy storage unit 80 generates heat. The pipe system can achieve thermal management of the energy storage unit 80 by circulating a working fluid. Specifically, the working fluid enters the second inlet chamber 21 from the first inlet chamber 11. The third pipes 30 introduce the working fluid from the second inlet chamber 21 into the energy storage unit 80, removing heat. The fourth pipes 40 then transport the heated working fluid back to the second outlet chamber 22, thus forming an effective heat dissipation cycle. This allows the energy storage unit 80 to operate within a suitable temperature range, improving energy storage efficiency and stability. In addition, the pipe system of this application forms an inlet channel through the first inlet chamber 11, the second inlet chamber 21 and the third pipe 30, and forms an outlet channel through the first outlet chamber 12, the second outlet chamber 22 and the fourth pipe 40. The inlet channel and the outlet channel are independent of each other, thereby providing a stable transmission path for the working fluid, avoiding mutual interference between the working fluids in the two channels, and improving the efficiency of thermal management.

[0052] It is understandable that setting at least two third pipe bodies 30 and at least two fourth pipe bodies 40 can accommodate at least two energy storage units 80. The number of energy storage units 80 corresponding to one third pipe body 30 and the number of energy storage units 80 corresponding to one fourth pipe body 40 are determined according to the specific needs of the energy storage system. Furthermore, each energy storage unit 80 can be equipped with one third pipe body 30 and one fourth pipe body 40, enabling individual thermal control of the energy storage unit 80 and reducing the impact of a failure in one third pipe body 30 or one fourth pipe body 40 on the pipe system. In addition, as the energy storage system expands or is upgraded, more third pipe bodies 30 and fourth pipe bodies 40 can be easily added to the pipe system to meet increased fluid transfer requirements, increasing the scalability of the pipe system. This allows the energy storage system to adapt to changing business needs without large-scale modifications, reducing the cost and difficulty of equipment upgrades.

[0053] To further optimize the connection settings of the pipe system, please refer again. Figure 1In some embodiments, the pipe system is used in an energy storage system. The first pipe 10 includes a first body 13 and a second body 14 connected to each other. The first body 13 is connected to the liquid cooler unit 60 of the energy storage system, and the second body 14 is connected to the second pipe 20. Both the first body 13 and the second body 14 have independently configured first inlet chambers 11 and first outlet chambers 12. Specifically, the first pipe 10 is divided into a first body 13 and a second body 14. The first body 13 is specifically connected to the liquid cooler unit 60 of the energy storage system and is responsible for receiving the working fluid from the liquid cooler unit 60 or supplying the working fluid to the liquid cooler unit 60 after it has been heated by the energy storage unit 80. The second body 14 is connected to the second pipe 20 and acts as a bridge between the energy storage unit 80 and the liquid cooler unit 60 for transferring the working fluid. This clear functional division improves the operating efficiency and management convenience of the pipe system, making the functions of each part of the first pipe 10 clearer and facilitating troubleshooting and maintenance. Furthermore, since the first body 13 and the second body 14 play different roles and are connected at different points in the energy storage system, the relevant parameters of the first body 13 and the second body 14 can be designed according to the respective needs of the liquid cooler unit 60 and the energy storage unit 80, such as interface size, pressure resistance, and transmission flow rate, to further improve the applicability of the pipe system.

[0054] To further optimize the configuration of the pipe system, in some embodiments, the pipe system is used in the energy storage system, with the first pipe 10 positioned at the top or bottom of the energy storage cabinet 50. Specifically, placing the first pipe 10 at the top of the energy storage system fully utilizes the space at the top of the device, avoiding horizontal spatial conflicts with other key components inside the energy storage system, such as the energy storage unit 80. For some energy storage systems with a compact layout, placing the first pipe 10 at the top can also improve space utilization, making the overall structure of the device more compact. Alternatively, the first pipe 10 can be placed at the bottom of the energy storage system, providing more stable support for the entire pipe system. Furthermore, since energy storage systems are typically placed on a relatively stable plane, the bottom position is relatively fixed and less susceptible to external vibrations and shaking. This reduces vibration during operation and improves the stability and reliability of the pipe system.

[0055] In some embodiments, there are at least two second tubes 20. At least two second tubes 20 mean more channels can be used for working fluid transport. Distributing at least two second tubes 20 evenly within the energy storage system allows the working fluid to contact the energy storage unit 80 more extensively, thereby avoiding localized overheating or uneven working fluid flow, improving the heat exchange efficiency of the tube system and the overall performance of the energy storage system. Based on this, the number and location of the at least two second tubes 20 can be flexibly configured according to different energy storage system requirements. For example, the appropriate number and size of second tubes 20 can be selected based on factors such as the scale, power, heat load, and space constraints of the energy storage system to achieve optimal working fluid transport. This allows the tube system to better adapt to various types and specifications of energy storage systems, improving its versatility and applicability. Furthermore, as the energy storage system expands or upgrades, more second tubes 20 can be easily added to meet increased fluid transport demands, enabling the energy storage system to adapt to changing business needs without large-scale modifications, reducing the cost and difficulty of equipment upgrades. Furthermore, at least two second pipe bodies 20 provide a certain degree of redundancy. Even if one second pipe body 20 fails, such as becoming blocked, leaking, or damaged, the other second pipe bodies 20 can still continue to operate, thereby reducing the impact on the entire pipe system and energy storage system, improving the reliability and stability of the pipe system, and reducing the risk of equipment downtime due to the failure of a single second pipe body 20. Moreover, a leakage self-locking device can be installed at the connection between the second pipe body 20 and the first pipe body 10, so that when a second pipe body 20 fails, the corresponding connection will directly self-lock, preventing further leakage and damage.

[0056] In some embodiments, the pipe system is made of thermal insulation material. Thermal insulation material has a low thermal conductivity coefficient, which can effectively reduce heat transfer between the inside of the pipe system and the external environment. In other words, in energy storage systems, using thermal insulation material can reduce heat loss of the working fluid during transmission, improving energy utilization efficiency. For example, for cooling media that need to be kept at low temperatures, thermal insulation material can prevent them from heating up too quickly in the pipe, thereby ensuring that the energy storage unit 80 can be continuously and effectively cooled. At the same time, thermal insulation material can also provide a stable temperature environment, preventing temperature changes in the working fluid from affecting the stability of other structures in the energy storage system, reducing thermal stress and fatigue damage to other structures within the energy storage system, extending the service life of the energy storage system, reducing the frequency of equipment maintenance and replacement, and further saving resources and costs.

[0057] In summary, by configuring the first pipe body 10 with independent first inlet chamber 11 and first outlet chamber 12, and configuring the second pipe body 20 with independent second inlet chamber 21 and second outlet chamber 22, and then directly connecting the first inlet chamber 11 of the first pipe body 10 to the second inlet chamber 21 of the second pipe body 20, and directly connecting the first outlet chamber 12 of the first pipe body 10 to the second outlet chamber 22 of the second pipe body 20, the number of connection points in the pipe system is greatly reduced, thus lowering the possibility of leakage due to numerous connection points. Simultaneously, a more direct and simple connection structure is formed, making the connection of the pipe system more stable and reducing the risk of leakage due to loose or unstable connections.

[0058] Accordingly, please refer to again Figure 1 This application also provides an energy storage system, including: an energy storage cabinet 50, and a pipe system as described in any of the above embodiments. The energy storage cabinet 50 has a receiving cavity 51, in which a liquid chiller 60, a power distribution device 70, and an energy storage unit 80 are placed; the first pipe 10 of the pipe system is connected to the liquid chiller 60; the third pipe 30 and the fourth pipe 40 of the pipe system are connected to the energy storage unit 80. The pipe system is used to realize the circulation of the working fluid in the energy storage system, and to realize heat exchange between the working fluid, the energy storage unit 80, and the liquid chiller 60 in a timely manner. That is, by circulating the working fluid in the liquid chiller 60, the pipe system can promptly remove the heat generated by the energy storage unit 80 during charging and discharging, keeping it operating within a suitable temperature range, thereby improving the charging and discharging efficiency, cycle life, and safety of the energy storage unit 80, and realizing efficient thermal management of the energy storage system. At the same time, the number of connection points in the pipe system is greatly reduced, which also reduces the possibility of leakage caused by a large number of connection points. This results in a more direct and simple connection structure, making the connection of the pipe system more stable and reducing the risk of leakage caused by loose or unstable connections, thereby improving the safety of the energy storage system.

[0059] To improve the ease of installation of the piping system, please refer to Figure 4 , Figure 4 This illustration shows a side view of the energy storage system provided in an embodiment of this application. In some embodiments, the side wall 56 of the energy storage cabinet 50 has a first installation port 52. The energy storage system also includes a first sealing plate, which covers the first installation port 52. Specifically, the first installation port 52 on the side wall 56 facilitates the installation of the pipe system. During installation, the entire pipe system is placed into the receiving cavity 51 through the first installation port 52, and then the first installation port 52 is sealed with the first sealing plate, thereby achieving the overall installation of the pipe system. Optionally, the first pipe 10 can also be placed into the receiving cavity 51 through the first installation port 52, and then installed with the second pipe 20, the third pipe 30, and the fourth pipe 40, further improving the installation convenience of the pipe system.

[0060] In some embodiments, the first mounting port 52 is located near the bottom of the side wall 56. This facilitates the overall installation of the tubing system at the bottom of the receiving cavity 51, providing more stable support for the entire tubing system. Furthermore, since energy storage systems are typically placed on a relatively stable plane, the bottom position is relatively fixed and less susceptible to external vibrations and shaking. Installing the entire tubing system at the bottom of the receiving cavity 51 also reduces vibration during operation, improving the stability and reliability of the tubing system. Optionally, the first tubing 10 can be placed into the receiving cavity 51 through the first mounting port 52 before being installed with the second tubing 20, the third tubing 30, and the fourth tubing 40, further enhancing the ease of installation of the tubing system.

[0061] Please see Figure 5 , Figure 5 This illustration shows another structural diagram of the energy storage system provided in the embodiments of this application. In some embodiments, the energy storage cabinet 50 includes: a body 53, a door frame 54, a first waterproof component, and a second waterproof component. The body 53 has a receiving cavity 51. The pipe system is disposed within the receiving cavity 51 and is detachably connected to the body 53. The door frame 54 has an installation channel near its bottom for accommodating the pipe system. The first waterproof component is disposed between the pipe system and the inner wall of the installation channel. The second waterproof component is disposed between the door frame 54 and the inner wall of the body 53. Thus, by providing a detachably connected door frame 54 and having an installation channel near its bottom, the installation of the pipe system is greatly facilitated. During production and installation, the door frame 54 can be disassembled first, and then the integrated pipe system can be easily placed into the corresponding position in the receiving cavity 51 and fixed. Then, the door frame 54 can be reinstalled, avoiding the problems of space constraints and inconvenient operation when installing the pipe system in the receiving cavity 51. This greatly improves the efficiency and accuracy of pipe system installation and reduces installation difficulty and time. In addition, by setting the first and second waterproof components, external moisture can be effectively prevented from entering the energy storage cabinet 50 through the gap between the pipe body and the installation channel, and moisture can be prevented from seeping into the receiving cavity 51 from the connection between the door frame 54 and the main body 53. This ensures that key components such as the liquid cooling unit 60, power distribution equipment 70, and energy storage unit 80 inside the energy storage cabinet 50 are not affected by moisture, thereby improving the reliability and stability of the equipment and extending its service life.

[0062] It is understandable that when the piping system is installed as a whole, in order to further reduce the number of connection points and the risk of leakage in actual operation, the quick-connect fitting between the first pipe body 10 and the second pipe body 20 can be eliminated, and the first pipe body 10 and the second pipe body 20 can be made into a single integrated piping system through methods such as thermofusion welding. In this case, the connection points on the piping system only exist between the liquid chiller unit 60 and the first pipe body 10, between the third pipe body 30 and the energy storage unit 80, and between the fourth pipe body 40 and the energy storage unit 80, thereby further reducing the risk of leakage.

[0063] Please refer to the following: Figure 6 and Figure 7 , Figure 6 This illustration shows another structural diagram of the energy storage system provided in an embodiment of this application; Figure 7 This illustration shows a schematic diagram of the top structure of the energy storage system provided in an embodiment of this application. In some embodiments, a second mounting opening 55 is provided on the top of the energy storage cabinet 50; the energy storage system also includes a second sealing plate, which covers the second mounting opening 55. Furthermore, since the pipe system needs to maintain its overall shape during the overall installation process, a significant amount of manpower is required. Therefore, this application can also install the pipe system from the top. The pipe system can be directly placed and fixed in a suitable position using a top-mounted installation method through the second mounting opening 55, avoiding the spatial obstacles and operational inconveniences that may be encountered when installing from the side or other positions. This makes the layout of the internal equipment of the energy storage cabinet 50 more reasonable and diverse, better meeting the installation needs of different functional components.

[0064] In some embodiments, the second sealing plate includes an insulation structure and a sealing structure, with the sealing structure disposed between the insulation structure and the energy storage cabinet 50. Specifically, the insulation structure effectively reduces the heat exchange rate between the inside and outside of the energy storage cabinet 50. This prevents external heat from entering the energy storage cabinet 50 in high-temperature environments and reduces heat loss from the inside of the energy storage cabinet 50 in low-temperature environments, thereby maintaining the operating temperature of the energy storage unit 80 and other electrical equipment within the energy storage cabinet 50 within a suitable range. This ensures the stable and efficient operation of the energy storage system and reduces energy loss and equipment aging caused by temperature changes. Furthermore, the sealing structure, located between the insulation structure and the energy storage cabinet 50, effectively prevents moisture from entering the interior of the energy storage cabinet 50 through the second mounting port 55 at the top, avoiding short circuits, corrosion, and performance degradation of the energy storage unit 80. This ensures that the interior of the energy storage cabinet 50 remains dry, guaranteeing the normal operation and service life of the equipment. Understandably, the sealed structure also prevents dust and debris from entering the energy storage cabinet 50, avoiding the accumulation of dust and debris that could affect heat dissipation and reduce electrical insulation performance, keeping the inside of the energy storage cabinet 50 clean, and further improving the reliability and stability of the energy storage system.
