Description

Technical Field

[0001] This utility model relates to the technical field of liquid cooling pipeline systems, specifically a liquid cooling pipeline system for an energy storage industrial and commercial liquid tank. Background Technology

[0002] With the widespread application of energy storage systems, data center servers, and high-heat-power electronic devices, liquid cooling technology has become a key heat dissipation method due to its excellent heat exchange efficiency. In liquid cooling systems, the reliable connection and disconnection of liquid cooling pipelines directly affect the delivery efficiency of the cooling medium and the system's sealing stability, making it a core technical aspect of liquid cooling module design.

[0003] Currently, common liquid cooling pipeline connection methods mainly include: threaded screw-in joints, ball valve joints, and quick-connect structures. While these structures have achieved basic liquid transport functions in certain scenarios, they still present the following significant problems in practical use:

[0004] Most existing quick-connect pipe fittings cannot automatically seal the inside of the pipe when the connection is broken. They require manual operation to close the valve or the installation of an external leak-proof structure, which is cumbersome and poses a risk of liquid leakage. If the connection is not made in time or the seals are aged, coolant leakage can easily occur, causing system contamination, conductive fluid corrosion, or personal injury risks, which are especially dangerous in energy storage systems.

[0005] Traditional threaded or clamp-type pipe fittings require tools for assembly and disassembly, which is not only time-consuming and labor-intensive but also difficult to operate in space-constrained environments. Furthermore, some quick-connect structures lack effective guidance for directional insertion, easily leading to skewed or reverse insertion, resulting in weak connections or failure to seal, thus affecting the stable operation of the system.

[0006] In existing technologies, some liquid-cooled connectors are only applicable to a single type of equipment, with complex structures and poor compatibility. Under conditions such as long-term thermal cycling, mechanical vibration, and frequent insertion and removal, their sealing performance and mechanical stability are prone to decline, resulting in high maintenance costs and hindering the modular and standardized rapid deployment and maintenance requirements of energy storage systems.

[0007] In summary, existing liquid-cooled connection systems generally suffer from problems such as a lack of automatic sealing, inconvenient connection structures for quick insertion and removal, complex operation, and susceptibility to misoperation. These issues make it difficult to meet the actual requirements of modern energy storage systems for liquid-cooled connection components that demand high safety, high efficiency, and high reliability. Therefore, there is an urgent need for a new type of liquid-cooled piping connection system with self-sealing upon disconnection, quick and reliable insertion, and foolproof positioning structure to improve the overall safety, maintainability, and assembly efficiency of the liquid-cooled system. Utility Model Content

[0008] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0009] Therefore, the technical solution adopted by this utility model is as follows: a liquid-cooled pipeline system for an energy storage industrial and commercial liquid tank. This system includes a first end pipe, a second end pipe, and stop sleeves and end pipe ports respectively fixed to the ends of the first and second end pipes. By providing a standardized connection structure at each pipe port, it ensures rapid connection between modules under space-constrained conditions, improving installation flexibility. The end pipe port includes a connecting lug, a sleeve, a valve lug slidably fitted inside the connecting lug, and an elastic element located inside the valve lug. The connecting lug has an internal flow channel for connecting to the inner cavity of the end pipe. When not connected, the valve lug, under the action of the elastic element, pushes forward to close the internal flow channel, achieving automatic sealing, preventing liquid leakage and impurity intrusion, and improving the reliability of system operation.

[0010] In a preferred example, the lug and the sleeve are semi-cylindrical structures, with their outer diameter matching the inner diameter of the valve lug. The valve lug is slidably mounted on one side of the lug and makes sealing contact with the end of the inner flow channel.

[0011] Specifically, this structure helps ensure accurate fit of the sealing surfaces, maintains stable internal pressure in the pipe during connection, and prevents leakage at the joints.

[0012] In a preferred example, when the two end pipe groups are connected, one lug pushes the valve lug on the opposite side back, so that the internal flow channel ports in the two lug groups are connected and connected.

[0013] Specifically, the connection process requires no additional operating mechanism and automatically opens the bidirectional valve, significantly improving connection efficiency and sealing safety.

[0014] In a preferred example, the stop sleeve includes a plurality of elastic claws evenly distributed along the circumferential direction for engaging with an annular locking groove provided on the outside of the lug.

[0015] Specifically, the end tube is quickly locked by the locking groove structure of the elastic gripper, without the need for threaded rotation or tool assistance, which significantly improves assembly efficiency.

[0016] In a preferred example, the elastic claws of the two locking sleeves are staggered and precisely engage with the annular locking groove when the two lug ends are in full contact.

[0017] Specifically, this staggered arrangement helps increase connection stability and seismic resistance, preventing loosening or leakage caused by vibration or displacement.

[0018] In a preferred example, a sealing gasket is provided on one side of the valve lug for resilient contact with the lug, and the gasket fits into the inner flow channel port to form a sealing contact.

[0019] Specifically, the sealing gasket improves the static sealing performance of the interface, and can maintain a long-lasting and reliable seal even in alternating hot and cold environments.

[0020] In a preferred example, the inner flow channel can be configured as an L-shaped structure, with one end connected to the inner cavity of the first or second end pipe, and the other end arranged vertically toward the valve lug.

[0021] Specifically, the L-shaped layout can reduce the connection depth, which is conducive to the compact arrangement of interfaces and saves equipment installation space.

[0022] The beneficial effects achieved by this utility model are as follows:

[0023] 1. In this utility model, by setting a sliding valve lug and a matching elastic element inside the end pipe assembly port, the valve lug automatically pushes out and closes the inner flow channel port under the action of the elastic element when not connected, thereby achieving automatic sealing when the pipeline is disconnected, preventing liquid leakage or external impurities such as air and dust from entering the liquid cooling system, and effectively ensuring the safety and cleanliness of the system operation.

[0024] 2. In this utility model, a locking sleeve and an annular locking groove on the outside of the lug are used to achieve quick insertion and reliable locking of the pipe port; at the same time, a foolproof guide structure is provided on the outside of the lug to avoid misalignment or incorrect orientation. The overall structure supports tool-free quick insertion and removal, greatly improving installation efficiency, facilitating equipment maintenance and system module replacement, and is suitable for scenarios such as energy storage systems that require frequent disassembly and assembly.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a liquid-cooled piping system for an energy storage industrial and commercial liquid tank.

[0035] This utility model provides a liquid-cooled piping system for an energy storage industrial and commercial liquid tank, suitable for rapid liquid connection and safe disconnection between energy storage systems and liquid cooling equipment. The system includes a first end pipe 100, a second end pipe 200, a stop sleeve 300, and an end pipe port 400.

[0036] like Figure 1 and Figure 2 As shown, the first end tube 100 and the second end tube 200 are respectively used to install on the two end devices that need fluid connection. The anti-insertion sleeve 300 is disposed between the first end tube 100 and the second end tube 200. It is provided with several elastic claws on its outside, which are evenly distributed in the circumferential direction to realize the elastic snap-fit ​​and locking function during connection.

[0037] like Figure 2 and Figure 3 As shown, both the first end tube 100 and the second end tube 200 are provided with end tube assembly ports 400. Each end tube assembly port 400 includes a connecting lug 410, a sleeve 420, and a valve lug 430 that slides within the connecting lug 410. The connecting lug 410 and the sleeve 420 are both semi-cylindrical in shape, with the same outer diameter, forming a plug-in connection. The connecting lug 410 has an internal flow channel 411 for connecting the internal liquid passages of the first end tube 100 and the second end tube 200.

[0038] The valve lug 430 is slidably mounted on the inner side of the lug 410, and its other side is also sleeved on the inner wall of the sleeve 420, so that it can slide axially during insertion and removal. In the unconnected state, the valve lug 430 is pushed forward by the elastic member 431 and abuts against the port of the inner flow channel 411, thereby sealing the inner flow channel 411 and preventing liquid leakage or the entry of external impurities.

[0039] like Figure 3 and Figure 4As shown, during the connection operation, the two end tube ports 400 are aligned and then mated together, with the insertion direction corrected by a guide structure. During insertion, the lug 410 of one end tube port 400 pushes the valve lug 430 inside the other end tube port 400 and causes it to retract under the action of the elastic element 431 until the inner flow channels 411 ports of the two lugs 410 are axially aligned and the fluid passage is connected. After insertion, the elastic claw on the anti-insertion sleeve 300 engages with the annular locking groove on the outer side of the sleeve 420 to reliably lock the first end tube 100 and the second end tube 200.

[0040] To ensure accurate positioning during the insertion process, the outer surface of the ear flap 410 is provided with a guide protrusion and groove structure. The structure cooperates with the claw on the anti-insertion sleeve 300 to form an insertion guide and anti-foolproof structure, which can effectively avoid skewed insertion or incorrect orientation.

[0041] If disassembly and separation are required, the operator can manually pull out the stop sleeve 300, and the elastic gripper will disengage from the locking groove, separating the two end pipe ports 400. At this time, the valve ear 430 will automatically reset and move forward under the action of the elastic element 431, re-sealing the inner flow channel 411, achieving rapid liquid cut-off and sealing, and preventing liquid leakage.

[0042] Furthermore, the elastic grippers of the two stop sleeves 300 can be designed as an interleaved structure, so that when the ends of the two ear flaps 410 are fully abutted, the grippers can be precisely engaged with the annular locking groove on the surface of the ear flaps 410, thereby improving the stability of the connector connection.

[0043] In addition, the inner flow channel 411 can be designed as an L-shaped structure, with one end connected to the inner cavity of the first end pipe 100 or the second end pipe 200, and the other end perpendicularly facing the sealing surface of the valve ear 430, thereby improving the sealing effect and liquid conduction efficiency.

[0044] With the above structural configuration, this utility model can not only achieve rapid docking and separation of liquid cooling pipes during use, but also has excellent sealing performance, locking stability and foolproof guiding capability. It is particularly suitable for use in energy storage systems, server liquid cooling systems or power module systems with high requirements for coolant connection and frequent disassembly and assembly.

[0045] Working principle and usage process of this utility model:

[0046] This utility model relates to a liquid-cooled piping system for industrial and commercial energy storage tanks. By incorporating liquid-cooled pipe ends with automatic sealing and quick-connect / remove capabilities, it enables safe and efficient connection and disconnection between liquid-cooled channels in the energy storage system. The system comprises a first end pipe 100, a second end pipe 200, a stop sleeve 300, and an end pipe assembly port 400, and features multiple functions including elastic locking, automatic sealing, and foolproof guidance.

[0047] Automatic sealing mechanism: The end pipe assembly port 400 includes a connecting lug 410, a sleeve 420, and a slidingly fitted valve lug 430. In the unconnected state, the valve lug 430 is pushed forward by the elastic member 431 to seal the port of the inner flow channel 411, preventing liquid leakage or contaminant entry.

[0048] Principle of insertion, unlocking, and connection: During the connection operation, the two end tube ports 400 are connected to each other. Under the guidance of the foolproof structure, the surface of the lug 410 of one end tube port 400 is aligned with the valve lug 430 of the other end tube port 400. During the insertion process, the lug 410 pushes the valve lug 430 back elastically until the inner flow channels 411 on the surfaces of the lugs 410 of the two end tube ports 400 are connected to each other. After connection, the stop sleeve 300 and the annular locking groove on the surface of the sleeve 420 engage to lock the two end tube ports 400 in the engagement state. The connection of the inner flow channels 411 of the two end tube ports 400 is achieved by connecting the first end tube 100 and the second end tube 200.

[0049] Guiding and error-proof structure: The outer surface of the ear flap 410 is provided with a protrusion and groove structure, which cooperates with the elastic claw on the anti-insertion sleeve 300 to form an insertion guiding and error-proof structure, ensuring the uniqueness of the connection direction and preventing reverse or skewed insertion.

[0050] Quick-connect and quick-disconnect connection: When disconnecting, pull out the stop sleeve 300, the gripper disengages from the locking groove, and the valve ear 430 resets and closes under the action of the elastic element 431, automatically cutting off the liquid seal.
