[0002] With the widespread application of cylindrical lithium-ion batteries in the new energy field, the heat dissipation problem of battery systems has received increasing attention. As a crucial component of the battery thermal management system, the performance of the liquid cooling system has a critical impact on the battery's safety, stability, and lifespan. Within the liquid cooling system, the expansion connection process between the liquid cooling pipes and the liquid cooling plates is a key step in ensuring system sealing and heat dissipation efficiency. However, current expansion connection fixtures suffer from limitations in operation, including limited expansion space, operational complexity, and poor compatibility. Utility Model Content This utility model aims to at least partially solve one of the technical problems in the related art.

[0003] Therefore, embodiments of this utility model propose a device for expanding and connecting a liquid cooling pipe and a liquid cooling plate.

[0004] The liquid cooling pipe and liquid cooling plate expansion joint device of this utility model embodiment includes a guide rail, a slider, a first fixing component, and a second fixing component. The slider is slidably connected to the guide rail along a first direction. The first fixing component is connected to the guide rail and is used to fix one of the liquid cooling pipe and the liquid cooling plate. The second fixing component is connected to the slider and is spaced apart from the first fixing component in the first direction. The second fixing component is used to fix the other of the liquid cooling pipe and the liquid cooling plate. The slider is used to drive the second fixing component to move relative to the first fixing component in the first direction so that the liquid cooling pipe and the liquid cooling plate are expanded and connected.

[0005] In some embodiments, the first fixing component includes a fixing plate and a gripper, the fixing plate being connected to the guide rail, and the gripper being rotatably connected to the fixing plate about an axis extending along the first direction, the gripper cooperating with the fixing plate to clamp the liquid cooling pipe.

[0006] In some embodiments, the fixing plate has a first limiting groove with an opening facing the gripper, the gripper has a second limiting groove with an opening facing the fixing plate, a portion of the liquid cooling tube is fitted into the first limiting groove, and another portion of the liquid cooling tube is fitted into the second limiting groove.

[0007] In some embodiments, the first limiting groove and / or the second limiting groove are adapted to the outer peripheral surface of the liquid cooling pipe.

[0008] In some embodiments, the second fixing component includes a first plate and a second plate, the first plate being detachably connected to the slider, the second plate extending along a second direction orthogonal to the first direction, and the second plate having a clearance hole extending along the first direction for clearing the water nozzle of the liquid cooling plate.

[0009] In some embodiments, the clearance hole penetrates the second plate along the first direction.

[0010] In some embodiments, the second plate has an opening at one end away from the first plate in the second direction, and the opening communicates with the clearance hole.

[0011] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device of the present invention further includes a cylinder. The cylinder is disposed on the side of the slider away from the first fixed component in the first direction. The cylinder includes a fixed part and a telescopic part. The fixed part is connected to the guide rail. The telescopic part is telescopic relative to the fixed part in the first direction. The telescopic part is connected to the slider.

[0012] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device of this utility model further includes a first connecting plate and a second connecting plate.

The second connecting plate is orthogonal to the first direction and detachably connected to the second fixing member. The telescopic part is detachably connected to the second connecting plate.

[0013] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device of this utility model further includes a handle, the handle is connected to the guide rail, and the handle and the slider are disposed opposite to each other on both sides of the guide rail.

[0017] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] like Figure 1 As shown, the liquid cooling pipe and liquid cooling plate expansion joint device 100 of this utility model embodiment includes a guide rail 1, a slider 2, a first fixing component 3, and a second fixing component 4. The slider 2 is slidably connected to the guide rail 1 along a first direction; the first fixing component 3 is connected to the guide rail 1 and is used to fix one of the liquid cooling pipe 200 and the liquid cooling plate 300. The second fixing component 4 is connected to the slider 2 and is spaced apart from the first fixing component 3 in the first direction. The second fixing component 4 is used to fix the other of the liquid cooling pipe 200 and the liquid cooling plate 300. The slider 2 is used to drive the second fixing component 4 to move relative to the first fixing component 3 in the first direction, so that the liquid cooling pipe 200 and the liquid cooling plate 300 are expanded and connected. For example, as Figure 1 As shown, the first direction is the length direction of guide rail 1, and the second direction is the height direction of guide rail 1.

[0019] In use, the liquid cooling pipe and liquid cooling plate expansion joint device 100 of this utility model first uses the first fixing component 3 to fix one of the liquid cooling pipe 200 and the liquid cooling plate 300, and the second fixing component 4 to fix the other of the liquid cooling pipe 200 and the liquid cooling plate 300. When the slider 2 drives the second fixing component 4 to move closer to the first fixing component 3 in the first direction, the liquid cooling pipe 200 and the liquid cooling plate 300 are subjected to uniform pressure at the expansion joint. This pressure causes a tight expansion joint connection to be formed between the port of the liquid cooling pipe 200 and the liquid cooling plate 300, ensuring the sealing between the liquid cooling pipe 200 and the liquid cooling plate 300.

[0020] The liquid cooling pipe and liquid cooling plate expansion joint device 100 of this embodiment simplifies the expansion joint process through the cooperation of the guide rail 1 and the slider 2. The operator only needs to control the slider 2 to move along the guide rail 1 to complete the expansion joint operation, reducing operational complexity. Simultaneously, this device allows expansion joint operations to be performed in limited spaces, solving the space-constrained problem in traditional expansion joint processes. Furthermore, since the first fixing component 3 and the second fixing component 4 can respectively fix the liquid cooling pipe 200 and the liquid cooling plate 300, the compatibility of the expansion joint device 100 is improved, allowing it to adapt to liquid cooling pipes 200 and liquid cooling plates 300 of different sizes and types.

[0021] In some embodiments, the first fixing component 3 includes a fixing plate 301 and a gripper 302. The fixing plate 301 is connected to the guide rail 1, and the gripper 302 is rotatably connected to the fixing plate 301 about an axis extending along a first direction. The gripper 302 cooperates with the fixing plate 301 to clamp the liquid cooling pipe 200.

[0022] like Figure 1 As shown, when the liquid cooling tube 200 is placed between the fixed plate 301 and the clamp 302, the clamp 302 can rotate and close, tightly clamping the liquid cooling tube 200. This allows the clamp 302 to accommodate liquid cooling tubes 200 of different diameters, improving the applicability of the device. Because the clamp 302 is rotatable, it can maintain the fixation of the liquid cooling tube 200 during the expansion process, and will not slide or shift even when the liquid cooling tube 200 is subjected to axial force.

[0023] Therefore, the clamp 302 allows the first fixing component 3 to accommodate liquid cooling tubes 200 of different sizes, increasing the flexibility and adaptability of the device. The rotation and closing of the clamp 302 can be performed manually or automatically, simplifying the installation process of the liquid cooling tube 200 and reducing operational difficulty. The fixing plate 301 provides stable support, and the clamping action of the clamp 302 ensures the stability of the liquid cooling tube 200 during the expansion process, which is crucial for ensuring the quality of the expansion. During the expansion process, the reliable fixing of the clamp 302 reduces the risk of slippage of the liquid cooling tube 200, thereby improving operational safety. Because the clamp 302 can tightly clamp the liquid cooling tube 200, the expansion process can be more precise, which helps to achieve better sealing and higher heat dissipation efficiency.

[0024] In some embodiments, the fixing plate 301 has a first limiting groove (not shown in the figure) with an opening 4022 facing the gripper 302, and the gripper 302 has a second limiting groove (not shown in the figure) with an opening 4022 facing the fixing plate 301. A portion of the liquid cooling pipe 200 is fitted in the first limiting groove, and another portion of the liquid cooling pipe 200 is fitted in the second limiting groove.

[0025] When the liquid cooling tube 200 is placed in the expansion device 100, a portion of it is guided into the first limiting groove of the fixing plate 301, while the other portion is guided into the second limiting groove of the clamp 302. This ensures that the liquid cooling tube 200 is precisely aligned between the two grooves, and due to the fit of their geometry, the position of the liquid cooling tube 200 is reliably fixed during the expansion process. The two limiting grooves allow for precise alignment of the liquid cooling tube 200 before expansion, which helps improve the quality and efficiency of the expansion process. The limiting grooves also increase the stability of the liquid cooling tube 200 during the expansion process, reducing the risk of poor expansion due to displacement of the liquid cooling tube 200. This design allows the operator to easily place the liquid cooling tube 200 in the correct position, simplifying the expansion operation and reducing operational complexity.

[0026] In some embodiments, the first limiting groove and / or the second limiting groove are adapted to the outer peripheral surface of the liquid cooling tube 200. When the liquid cooling tube 200 is placed in the expansion device 100, the shape and size of the limiting groove match the outer peripheral surface of the liquid cooling tube 200, which can accurately guide and fix the liquid cooling tube 200, ensuring accurate alignment between the liquid cooling tube 200 and the liquid cooling plate 300 during the expansion process. Due to the compatibility between the liquid cooling tube 200 and the limiting groove, the liquid cooling tube 200 is more stable during the expansion process, reducing expansion defects caused by movement or vibration. Since the liquid cooling tube 200 can be placed quickly and accurately in the limiting groove, this reduces operation time and improves production efficiency.

[0027] In some embodiments, the second fixing component 4 includes a first plate 401 and a second plate 402. The first plate 401 is detachably connected to the slider 2, and the second plate 402 extends along a second direction orthogonal to the first direction. The second plate 402 has a clearance hole 4021 extending along the first direction, which is used to avoid the water nozzle of the liquid cooling plate 300.

[0028] For example, the first plate 401 is detachably connected to the slider 2 by screws or bolts. The first plate 401, detachably connected to the slider 2, serves as part of the expansion joint device 100, providing support and fixation during the expansion process. The second plate 402 extends along a second direction orthogonal to the first direction; it also serves to fix the liquid cooling plate 300 and ensure that the position of the liquid cooling plate 300 remains unchanged during the expansion process. Specifically, as... Figure 1 As shown, the liquid cooling plate 300 abuts against the side of the second plate 402 adjacent to the clamp 302 in the first direction to fix the liquid cooling plate 300. The second plate 402 is provided with clearance holes 4021 extending in the first direction. The purpose of these holes is to avoid the water nozzle on the liquid cooling plate 300 so as not to interfere with or damage the water nozzle during the expansion process.

[0029] During the expansion process, the first plate 401 is connected to the slider 2, and the first plate 401 moves accordingly as the slider 2 moves. Since the extension direction of the second plate 402 is orthogonal to the first direction, it can provide additional support for the liquid cooling plate 300, while the setting of the clearance hole 4021 ensures that the water nozzle is not obstructed.

[0030] The clearance hole 4021 allows the expansion joint device 100 to adapt to the liquid cooling plate 300 with a water nozzle, increasing the device's applicability. Due to the presence of the clearance hole 4021, the water nozzle is protected during the expansion process, avoiding potential damage and ensuring its functionality and integrity. The operator need not worry that the water nozzle on the liquid cooling plate 300 will obstruct the expansion process, simplifying the operation. The second plate 402 provides additional support, helping to enhance the stability of the liquid cooling plate 300 during the expansion process. Because both the liquid cooling plate 300 and the water nozzle are properly secured and protected, the quality of the expansion connection is improved. The detachable connection between the first plate 401 and the slider 2 provides greater flexibility, facilitating maintenance and component replacement.

[0031] In some embodiments, the clearance hole 4021 penetrates the second plate 402 along a first direction. The clearance hole 4021 is not merely an opening on the surface of the second plate 402, but rather penetrates the entire second plate 402 along the first direction (i.e., the expansion direction). When the liquid cooling plate 300 is placed in the expansion device 100, its water nozzles correspond to the position of the clearance hole 4021. Because the clearance hole 4021 penetrates the second plate 402, the water nozzles of the liquid cooling plate 300 can protrude from the other side of the second plate 402, thus avoiding any obstruction during the expansion process. The penetrating clearance hole 4021 ensures that the water nozzles of the liquid cooling plate 300 are not interfered with during the expansion process, thereby protecting the structural integrity and functionality of the water nozzles. Since the presence of the water nozzles does not affect the expansion process, the operator can perform the expansion operation more quickly, improving production efficiency. This arrangement allows the expansion device 100 to adapt to various configurations of the liquid cooling plate 300, effectively performing expansion even if the water nozzle positions on the liquid cooling plate 300 are different.

[0032] In some embodiments, the second plate 402 has an opening 4022 at one end away from the first plate 401 in the second direction, and the opening 4022 communicates with the clearance hole 4021. When fixing the liquid cooling plate 300, the water nozzle on the liquid cooling plate 300 can be placed in the clearance hole 4021 through the opening 4022. After the expansion joint is completed, the water nozzle on the liquid cooling plate 300 can be quickly removed from the clearance hole 4021 through the opening 4022, which improves the disassembly and assembly efficiency of the liquid cooling plate 300, thereby improving production efficiency.

[0033] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device 100 of this utility model further includes a cylinder 5, which is disposed in a first direction on the side of the slider 2 away from the first fixing member 3. The cylinder 5 includes a fixing part 501 and a telescopic part 502. The fixing part 501 is connected to the guide rail 1, and the telescopic part 502 is telescopic relative to the fixing part 501 in a first direction. The telescopic part 502 is connected to the slider 2.

[0034] Specifically, when it is necessary to expand and connect the liquid cooling pipe 200 and the liquid cooling plate 300, the operator can activate the cylinder 5, and the telescopic part 502 begins to extend and retract under the action of air pressure. The extension and retraction of the telescopic part 502 drives the slider 2 and the second fixed part 4 to move along the first direction, applying pressure to the liquid cooling pipe 200 and the liquid cooling plate 300 to complete the expansion and connection process. Once the expansion and connection is completed, the cylinder 5 can release the pressure, the telescopic part 502 retracts, and the slider 2 and the second fixed part 4 return to their initial positions, ready for the next operation.

[0035] The use of cylinder 5 automates the expansion joint process, reducing the complexity of manual operation and improving production efficiency. Cylinder 5 provides precise pressure control, ensuring uniform and consistent pressure during the expansion joint process. Automated operation reduces operation time, increases production efficiency, and also reduces errors caused by manual operation. The automated expansion joint process reduces the operator's labor intensity and improves the operator's working environment. The automated expansion joint process reduces the operator's operation under high pressure, improving safety. The precise control provided by cylinder 5 makes the expansion joint process more repeatable, helping to improve the quality and consistency of the expanded joint.

[0036] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device 100 of this utility model further includes a first connecting plate 6 and a second connecting plate 7. The first connecting plate 6 is disposed in a first direction on the side of the slider 2 away from the first fixing member 3. The first connecting plate 6 is orthogonal to the first direction and detachably connected to the guide rail 1. The fixing part 501 is disposed on the side of the first connecting plate 6 adjacent to the slider 2 and detachably connected to the first connecting plate 6. The second connecting plate 7 is orthogonal to the first direction and detachably connected to the second fixing member 4. The telescopic part 502 is detachably connected to the second connecting plate 7.

[0037] For example, the first connecting plate 6 is detachably connected to the guide rail 1 by screws or bolts. The first connecting plate 6 is located on the side of the slider 2 away from the first fixing member 3, orthogonal to the first direction, and detachably connected to the guide rail 1, allowing for easy installation or removal when necessary. The fixing part 501 is located on the side of the first connecting plate 6 adjacent to the slider 2 and can be detachably connected to the first connecting plate 6 by screws or bolts; the detachability of the fixing part 501 facilitates easy adjustment or replacement. The second connecting plate 7 is orthogonal to the first direction and can be connected to the second fixing member 4 by screws or bolts, allowing for easy installation or removal when necessary. The telescopic part 502 can be detachably connected to the second connecting plate 7 by screws or bolts; the detachability of the telescopic part 502 facilitates easy adjustment or replacement.

[0038] During the expansion process, the first connecting plate 6 and the second connecting plate 7 are connected to the guide rail 1 and the second fixing component 4, respectively, providing stable support. The telescopic part 502 is connected to the second connecting plate 7. When the cylinder 5 operates, the extension and retraction of the telescopic part 502 will cause the second connecting plate 7 and the second fixing component 4 to move relative to the first connecting plate 6 and the first fixing component 3, completing the expansion of the liquid cooling pipe 200 and the liquid cooling plate 300. Once the expansion is completed, the cylinder 5 can release the pressure, the telescopic part 502 retracts, and all connecting plates and fixing components 501 return to their initial positions, ready for the next operation.

[0039] The detachable design allows for the replacement or adjustment of individual components as needed, increasing the flexibility of the device. When maintenance or component replacement is required, the operator can easily disassemble and install the various connecting plates and fixing parts 501, simplifying the maintenance process. By replacing connecting plates and fixing parts 501 of different sizes or shapes, the device can accommodate liquid cooling pipes 200 and liquid cooling plates 300 of different specifications, expanding its applicability. The detachable design helps ensure the secure connection of each component, reducing safety risks caused by loose or damaged components.

[0040] In some embodiments, the liquid cooling pipe and liquid cooling plate expansion joint device 100 of this utility model embodiment further includes a handle 8, which is connected to the guide rail 1, and the handle 8 and the slider 2 are disposed opposite to each other on both sides of the guide rail 1.

[0041] The handle 8 is connected to the guide rail 1 and is positioned opposite the slider 2 on both sides of the guide rail 1. This arrangement allows the operator to easily grip the handle 8 and control the movement of the slider 2 during operation. The position and arrangement of the handle 8 make it easier for the operator to apply force, thereby controlling the movement of the slider 2 and completing the expansion connection process.

[0042] Specifically, the operator can grip handle 8 and apply force to move slider 2 on guide rail 1. The handle 8 makes it easier for the operator to control the movement of slider 2, improving operational convenience and efficiency. By gripping handle 8, the operator can control the movement of slider 2, reducing the risk of accidental injury from direct contact with slider 2. The handle 8 also helps the operator maintain stability during operation, improving operational stability.
