[0042] The specific embodiments of the application have been shown by way of example in the above figures, and will be described in more detail hereafter. These figures and this written description are not intended to limit the scope of the inventive concept in any way, but rather to illustrate the inventive concept by reference to specific embodiments. DETAILED DESCRIPTION

[0043] As described in the background, such electrical equipment refers to the equipment that generates heat in the working state and needs to be cooled by a complete liquid cooling system to deliver cooling liquid for heat dissipation, such as an electric pile cabinet. The electric pile cabinet has a plurality of charging modules in the cabinet body, and the cooling liquid needs to cool each charging module. Since the liquid cooling system connects each charging module using a separate liquid cooling pipeline, when one of the liquid cooling pipeline openings is disassembled during the maintenance of the liquid cooling system, the cooling liquid is often spilled from the pipeline opening. Not only is the cooling liquid in the liquid cooling system wasted, but the operating environment is also polluted, making the maintenance process of the liquid cooling system troublesome.

[0044] Therefore, in the embodiments of the application, a bidirectional stop valve is arranged at the interface between the liquid cooling pipeline and the electrical module. The operator can disassemble the liquid cooling pipeline opening without liquid leakage. The workload of the operator is significantly reduced, the maintenance process is more efficient and convenient, and since there is no problem of cooling liquid leakage during disassembly, the operation process is cleaner and the cleanliness of the working environment is improved. The use of the bidirectional stop valve reduces the risk of cooling liquid leakage, ensures the long-term stable operation of the liquid cooling system, and improves the reliability of the electrical equipment.

[0045] The exemplary embodiments will be described in detail hereinbelow with reference to the drawings. Where the description refers to accompanying drawings, same numerals in different drawings represent same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0047] Reference Figure 1 , Figure 4 and Figure 5The embodiment of the present application provides a liquid cooling system, which comprises a liquid cooling unit 100 and a liquid cooling pipeline, and the liquid cooling unit 100 provides cooling liquid to an electrical module 001 through at least the liquid cooling pipeline.

[0048] The first end of the liquid cooling pipeline is in communication with the liquid cooling unit 100.

[0049] The second end of the liquid cooling pipeline is provided with a bidirectional stop valve, and the second end of the liquid cooling pipeline is in communication with the electrical module 001 through the bidirectional stop valve.

[0050] It can be known that the liquid cooling unit 100 provides cooling liquid to the electrical module 001 through the liquid cooling pipeline, so that the heat dissipation efficiency of the electrical element is improved; the bidirectional stop valve can close the liquid flow in the direction of the second end of the liquid cooling pipeline and the direction away from the second end of the liquid cooling pipeline when needed, and the cooling liquid cannot leak from the two open ends when the liquid cooling pipeline is disassembled.

[0051] The bidirectional stop valve can be a bidirectional stop valve controlled by a needle valve core of a valve port, the needle valve core is an elongated conical part that can move up and down in the valve body, the tip of the valve core is tightly combined with the valve seat to achieve good sealing, the valve seat is a part matched with the valve core, and usually has a small hole matched with the shape of the needle to ensure good sealing and flow control, and the valve design allows fluid to enter and flow out from any direction, and is suitable for systems that need bidirectional flow control. During use, the valve core moves up and down in the valve seat by rotating a hand wheel or operating an actuator, so that the cross-sectional area through which the fluid passes is changed, so that the flow is accurately controlled or the valve is closed.

[0052] The bidirectional stop valve can also be an electric stop valve, and the electric stop valve has an electric actuator composed of a motor and a gear, which is used to drive the up-and-down movement of the valve rod. After the electric actuator receives a control signal, the motor is driven to rotate, and the valve rod is driven to move up and down through the gear transmission, so that the valve is opened or closed. The electric stop valve can be controlled by an external electric signal, which saves manpower.

[0053] The bidirectional stop valve can also be a pneumatic stop valve, and the pneumatic actuator of the pneumatic stop valve is composed of a cylinder and a piston, which drives the movement of the valve rod by using compressed air. The pneumatic stop valve drives the valve rod to move up and down by controlling the air pressure entering the cylinder, so as to open or close the valve. The pneumatic stop valve is usually used in occasions that need rapid response and remote control.

[0054] It should be noted that as long as the bidirectional stop valve can be closed without causing cooling liquid leakage when the liquid cooling pipeline is disassembled, the embodiment of the present application does not excessively limit the type of bidirectional stop valve.

[0055] By setting the bidirectional stop valve at the interface of the liquid cooling pipeline and the electrical module, the worker can individually disassemble the liquid cooling pipeline nozzle without liquid leakage, the worker's workload is significantly reduced, the maintenance process is more efficient and convenient, and since there is no problem of cooling liquid leakage during disassembly, the operation process can be cleaner and the cleanliness of the working environment is improved; the use of the bidirectional stop valve reduces the risk of cooling liquid leakage, ensures the long-term stable operation of the liquid cooling system, and improves the reliability of the electrical equipment; by reducing the waste of cooling liquid and reducing the maintenance complexity, the operation and maintenance cost of the system is effectively controlled; reducing cooling liquid leakage not only helps environmental protection, but also improves the safety of the system, avoiding possible safety hazards caused by cooling liquid leakage.

[0056] In some possible embodiments, the liquid cooling pipeline includes a liquid inlet pipeline 210 and a liquid return pipeline 220; the number of bidirectional stop valves is multiple, and the multiple bidirectional stop valves include a first stop valve 310 and a second stop valve 320.

[0057] The first end of the liquid inlet pipeline 210 is in communication with the liquid outlet end of the liquid cooling unit 100, and the second end of the liquid inlet pipeline 210 is in communication with the water inlet of the electrical module 001 through the first stop valve 310.

[0058] The first end of the liquid return pipeline 220 is in communication with the liquid outlet end of the liquid cooling unit 100, and the second end of the liquid return pipeline 220 is in communication with the water outlet of the electrical module 001 through the second stop valve 320.

[0059] It can be known that the first end of the liquid inlet pipeline 210 is in communication with the liquid outlet end of the liquid cooling unit 100, responsible for delivering cooling liquid to the electrical module 001; the first end of the liquid return pipeline 220 is in communication with the liquid outlet end of the liquid cooling unit 100, responsible for returning cooling liquid from the electrical module 001 to the liquid cooling unit; the first stop valve 310 is located at the second end of the liquid inlet pipeline 210, controlling the water inlet of the electrical module 001 into which the cooling liquid enters; the second stop valve 320 is located at the second end of the liquid return pipeline 220, controlling the water outlet of the electrical module 001 from which the cooling liquid returns.

[0060] It should be noted that the second end of the liquid inlet pipeline 210 refers to the end of the pipeline away from the liquid cooling unit. It is the outlet of the cooling liquid from the liquid cooling unit from the liquid inlet pipeline 210 to the electrical module 001; the second end of the liquid return pipeline 220 refers to the end of the pipeline away from the liquid cooling unit, which is the inlet of the cooling liquid from the electrical module 001 that has absorbed heat from the liquid return pipeline 220 to the liquid cooling unit.

[0061] By installing the first stop valve 310 at the second end of the liquid inlet pipeline 210 and the second stop valve 320 at the second end of the liquid return pipeline 220, the system can accurately control the circulation of the cooling liquid. This design allows the flow of cooling liquid to be closed when needed, facilitating partial isolation and maintenance of the system.

[0062] In some possible embodiments, the liquid inlet pipeline 210 includes a first main pipeline 211 and a plurality of first branch pipelines 212 connected in series.

[0063] The water inlet end of the first main pipeline 211 is in communication with the liquid outlet end of the liquid cooling unit 100, and the water outlet end of the first main pipeline 211 is in communication with a plurality of water inlets of the electrical module 001 through the plurality of first branch pipelines 212.

[0064] It can be understood that the first main pipeline 211 is a part of the liquid inlet pipeline that leads the cooling liquid to be used in the liquid cooling unit 100, and the plurality of first branch pipelines 212 distribute the cooling liquid to be used to each part of the electrical module 001, such as the plurality of charging modules of the battery cabinet.

[0065] By dividing the liquid inlet pipeline 210 into the first main pipeline 211 and the plurality of first branch pipelines 212, the system can more evenly and effectively distribute the cooling liquid. The first main pipeline 211 serves as the main pipeline to ensure stable supply of the cooling liquid, and the plurality of first branch pipelines 212 distribute the cooling liquid to each part of the electrical module 001. This branch structure allows independent management and adjustment of the cooling demand of each part of the electrical module 001, improving the flexibility of the system. By optimizing the distribution path of the cooling liquid, the system can more effectively deliver the cooling liquid to the electrical module 001, improving the overall heat dissipation efficiency.

[0066] In some possible embodiments, the liquid inlet pipeline 210 includes a first communication pipe 213.

[0067] The middle part of the first communication pipe 213 is in communication with the water outlet end of the first main pipeline 211, and the first communication pipe 213 is provided with a plurality of water outlets arranged in series. The first communication pipe 213 is in communication with the plurality of first branch pipelines 212 through the plurality of water outlets.

[0068] It can be understood that the cooling liquid flows from the first main pipeline 211 into the first communication pipe 213, and then is distributed to the plurality of first branch pipelines 212 from the first communication pipe 213. This multi-point distribution mode ensures that the cooling liquid can reach each part of the electrical module at the same time.

[0069] By providing multiple water outlets on the first communication pipe 213, the cooling liquid can be evenly distributed to the multiple first branch pipes 212, which can ensure that each part of the electrical module 001 can obtain sufficient cooling liquid and avoid local overheating; the design of the multiple water outlets and the first branch pipes 212 makes the system more modular, and the staff can more easily check and replace individual first branch pipes 212 without affecting the operation of the entire system, reducing the complexity and time cost of maintenance; more efficient cooling liquid distribution reduces energy consumption, thereby reducing the operating cost of the system; uniform cooling liquid distribution reduces the risk of local overheating, improving the reliability and service life of the electrical equipment.

[0070] In some possible embodiments, the liquid return pipe 220 includes a second main pipe 221 and multiple second branch pipes 222 connected thereto.

[0071] The water outlet end of the second main pipe 221 is in communication with the liquid return end of the liquid cooling unit 100, and the water inlet end of the first main pipe 211 is in communication with the multiple water outlets of the electrical module 001 through the multiple second branch pipes.

[0072] It can be understood that the water outlet end of the second main pipe 221 is in communication with the liquid return end of the liquid cooling unit 100, and the cooling liquid returned from the electrical module 001 is transported back to the liquid cooling unit for recooling and circulation; each second branch pipe 222 collects the cooling liquid from each part of the electrical module 001 and transports it to the second main pipe 221.

[0073] By dividing the liquid return pipe 220 into the second main pipe 221 and the second branch pipes 222, the system can more effectively collect and transport the cooling liquid back to the liquid cooling unit; the cooling liquid is collected from the electrical module 001 by the second branch pipes 222 and is collected into the second main pipe 221, and such a branch structure ensures the rapid return of the cooling liquid, reduces the residence time in the pipe, and improves the circulation efficiency of the entire system; when a part of the electrical module 001 needs to be repaired or maintained, only the second branch pipe 222 related to the part can be closed without affecting the normal operation of the electrical module 001, reducing the impact on the entire system and simplifying the maintenance process.

[0074] In some possible embodiments, the liquid inlet pipe 210 includes a second communication pipe 223.

[0075] The middle part of the second communication pipe 223 is in communication with the water inlet end of the second main pipe 221; the second communication pipe 223 is provided with multiple water inlets arranged in sequence, and the second communication pipe 223 is in communication with the multiple second branch pipes 222 through the multiple water inlets.

[0076] It can be understood that the second branch pipe 222 recycles the high-temperature cooling liquid from the electrical module 001, the second communication pipe 223 inlet communicates with the plurality of second branch pipes 222 in turn, and the second branch pipe 222 collects the cooling liquid from the corresponding inlet, and the second communication pipe 223 makes the cooling liquid flow from the second branch pipe 222 to the second main pipe 221.

[0077] In actual use, due to this circulation process (the liquid cooling unit 100→the first main pipe 211→

[0078] The first communication pipe 213→the first branch pipe 212→the electrical module 001→the second branch pipe 222→the second communication pipe 223→the second main pipe 221→the liquid cooling unit 100), if a common two-way joint is installed at the communication place of the first branch pipe 212 and the electrical module 001, a common two-way joint is installed at the communication place of the second branch pipe 222 and the electrical module 001, or a bidirectional stop valve is installed at the communication place of the first communication pipe 213 and the first branch pipe 212 and a bidirectional stop valve is installed at the communication place of the second communication pipe 223 and the second branch pipe 222 according to the prior art, the first branch pipe 212 and the second branch pipe 222 remain the cooling liquid. When any first branch pipe 212 and second branch pipe 222 are disassembled, the disassembled end of the first branch pipe 212 and the second branch pipe 222 is not closed, and the cooling liquid in the first branch pipe 212 and the second branch pipe 222 will inevitably flow out to the operation site, which not only causes waste, but also pollutes the operation site. In the embodiment of the present application, the first stop valve 310 can block the port of the first branch pipe 212 when the first branch pipe 212 is disassembled, and the second stop valve 320 can block the port of the second branch pipe 222 when the second branch pipe 222 is disassembled, so that the cooling liquid leakage is avoided.

[0079] It should be noted that when the liquid cooling system is maintained, generally only the first branch pipe 212 and the second branch pipe 222 connected with the electrical module 001 are disassembled, so the present application only considers the case that the disassembly of the first branch pipe 212 and the second branch pipe 222 connected with the electrical module 001 causes the cooling liquid leakage, and the end of the first branch pipe 212 and the second branch pipe 222 away from the connection with the electrical module 001 will not cause the cooling liquid leakage in the maintenance of the liquid cooling system, and it is concluded that the embodiment of the present application can solve the problem of troublesome maintenance of the liquid cooling system.

[0080] The design of the second communication pipe 223 allows the cooling liquid to be distributed to each second branch pipe 222 through multiple water inlets before entering the second main pipe 221. This design ensures uniform collection of cooling liquid, improves the cooling efficiency of each electrical module 001, optimizes the distribution and return path of cooling liquid, and enables the system to more effectively deliver cooling liquid to each electrical module 001, thereby improving overall heat dissipation efficiency, which helps maintain the normal operation of electrical equipment 001 and prolong its service life.

[0081] In some possible embodiments, the first end of the liquid cooling pipe 200 is detachably connected to the liquid cooling unit 100.

[0082] It can be understood that the first end of the liquid cooling pipe 200 is detachably connected to the liquid cooling unit 100, which is usually achieved through quick couplings, flanges, or threaded connections, allowing quick connection or disconnection without the need for special tools.

[0083] In the liquid cooling system, maintenance and repair often require inspection, replacement, or cleaning of the liquid cooling unit or pipe. Detachable connection allows maintenance personnel to quickly disconnect the liquid cooling pipe 200, making it easier to access and handle the components that need maintenance. This design reduces the time and complexity of disassembly and reinstallation, reducing labor intensity during maintenance. Detachable connection not only simplifies the maintenance process but also improves the flexibility of the system, for example, when replacing the liquid cooling unit 100 or reconfiguring the pipe layout, detachable connection makes these adjustments easier and faster.

[0084] Reference Figure 3 In some possible embodiments, the first end of the liquid cooling pipe 200 and the liquid cooling unit 100 are provided with a union joint 400.

[0085] The liquid cooling unit 100 is provided with a union nut 500, which is rotatably arranged on the liquid cooling unit 100. The union nut 500 is threadedly connected to the union joint 400 of the first end of the liquid cooling pipe 200 and the liquid cooling unit 100.

[0086] The union joint 400 is a device that allows quick connection and disconnection of pipes, commonly used in pipe systems that require frequent disassembly and reconnection. The design of the union nut 500 allows connection and disconnection by rotating the union nut 500 itself without rotating the pipe.

[0087] In some embodiments, the union nut 500 is provided with a gasket to meet the IP level sealing requirements of different regions.

[0088] The union nut 500 is used to fix and seal the through point of the liquid cooling pipeline 200 on the partition of the liquid cooling unit 100. By thread connection and compression of the O-ring, the union nut 500 can provide additional sealing and mechanical stability. The IP (Ingress Protection) level is a standard defined by the International Electrotechnical Commission (IEC) to evaluate the protection capability of the device shell against external substances such as dust and water. The IP level usually consists of two numbers, the first number represents the protection level against solid particles, and the second number represents the protection level against liquids.

[0089] In the liquid cooling system, maintenance and repair usually require disconnecting and reconnecting the pipeline. By using the union joint 400 and the union nut 500, maintenance personnel can quickly disconnect the liquid cooling pipeline 200 from the liquid cooling unit 100 without rotating or moving the liquid cooling pipeline 200 itself, simplifying the disassembly and reinstallation process, making the maintenance and repair process of the cooling system more convenient; the thread connection of the union joint 400 and the union nut 500 provides reliable sealing, reducing the risk of cooling liquid leakage, and improving the operation reliability of the system; due to the more efficient maintenance and repair process, the downtime of the system is shortened, thereby improving the availability of the equipment and the production efficiency.

[0090] Reference Figure 2 In some possible embodiments, the water outlet end of the first main pipeline 211 is connected to the first communication pipe 213 through a first pipeline tee joint 610.

[0091] The water outlet end of the second main pipeline 221 is connected to the second communication pipe 223 through a first pipeline tee joint 610.

[0092] The first end of the first branch pipeline 212 and the second branch pipeline 222 is provided with a plug-in connector 700, and the water outlets between the first communication pipe 213 and the plug-in connector 700 are connected through a second pipeline tee joint 620.

[0093] The water outlets between the second communication pipe 223 and the plug-in connector 700 are connected through a second pipeline tee joint 620.

[0094] It can be understood that the connection through the first pipeline tee joint 610 allows the cooling liquid to branch from the first main pipeline 211 to the first communication pipe 213, while ensuring that the cooling liquid converges from the second communication pipe 213 to the second main pipeline 621; the plug-in connector 700 allows the first branch pipeline 212 and the first communication pipe 213, the second branch pipeline 222 and the second communication pipe 223 to have fixed points, and the second pipeline tee joint 620 allows the first branch pipeline 212 and the first communication pipe 213, the second branch pipeline 222 and the second communication pipe 223 to be connected.

[0095] By using the primary pipeline tee joint 610 and the secondary pipeline tee joint 620, the system can flexibly manage the flow path of the cooling liquid, and this design provides flexibility for multi-point connection, ensures that the electrical module 001 can obtain the required amount of cooling liquid, and improves the cooling efficiency of the system; the use of the primary pipeline tee joint 610 and the secondary pipeline tee joint 620 makes the pipeline connection more modular, facilitating disassembly and reconfiguration when needed, and the design of the interface plug 700 further simplifies the connection and disconnection process, reducing the complexity of maintenance.

[0096] The embodiment of the application provides an electrical equipment, which comprises the liquid cooling system.

[0097] The electrical equipment integrates the liquid cooling system designed above, comprising the liquid cooling unit 100 and the liquid cooling pipeline, the liquid cooling unit 100 realizes circulation of the cooling liquid through the liquid cooling pipeline, and directly provides cooling for electrical elements in the electrical equipment. The design features of the liquid cooling system, such as detachable connection, union joint, union nut, and multi-stage pipeline tee joint, are all applied to the electrical equipment to optimize the flow and management of the cooling liquid.

[0098] Through effective heat dissipation management, the operating temperature of the electrical equipment is controlled within a safe range, reducing the risk of failure caused by overheating and improving the reliability of the equipment; higher heat dissipation capacity allows the electrical equipment to operate at higher power, thereby improving the performance of the equipment; the modular and detachable design simplifies the maintenance process, reduces the time and manpower required for maintenance, and thus reduces the maintenance cost.

[0099] It should be noted that the electrical equipment in the embodiment of the application refers to equipment that generates heat in the working state and needs to be cooled by cooling liquid, which can refer to an electric pile cabinet. The electric pile cabinet belongs to the front-end equipment of a charging pile, and can also be combined with a large-scale energy storage to form a back-end and front-end equipment application of a charging pile. The electric pile cabinet is an important development point of the new energy charging and storage combination industry, and plays an important role as an independent circulating liquid cooling system of the electric pile cabinet, and also plays a key role in the normal charging and discharging heat dissipation operation of the entire electric pile cabinet system. Therefore, the embodiment of the application integrates the liquid cooling unit 100 at the upper part.

[0100] The electric pile cabinet has a plurality of charging modules in the cabinet body, and the cooling liquid needs to cool each charging module, that is, the first branch pipeline 212 is communicated with each charging module through the first stop valve 310 to transport the cooling liquid with a cooling effect.
