Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation, and in particular to a water-cooling pipeline circulation heat dissipation structure of a motor. Background Art

[0002] Motor heat dissipation methods vary depending on the cooling medium, heat transfer mechanism, and application. Their core goal is to control motor temperature rise, extend motor life, and increase power density. Some existing motors utilize cooling water pipes located outside the motor housing to circulate heat.

[0003] For example, Chinese patent publication number CN119134790A discloses a water-cooled permanent magnet motor, which relates to the field of permanent magnet motor assembly technology. The motor comprises a permanent magnet motor body with a plurality of pipe grooves on its periphery, a folded section, and cooling pipes 1 and 2 installed in the pipe grooves in alternating sections. A cooling pipe limiting mechanism comprises an outer support shell mounted on the outside of the permanent magnet motor body, and a limiting assembly for limiting the position of cooling pipes 1 and 2. An on-off switching mechanism comprises a bracket fixedly mounted on the outer support shell, an external pipe bracket mounted on the bracket, and an on-off switching assembly. The on-off switching assembly is used to control the connection and disconnection between the liquid inlet and outlet pipes and connector 1 or connector 2. The cooling pipes do not need to be disassembled when replacing the permanent magnet motor body. The cooling pipes can be replaced without shutting down the permanent magnet motor body. When one set of cooling pipes 1 or cooling pipe 2 is removed, the other set of cooling pipes can still operate normally to cool the permanent magnet motor body.

[0004] This application achieves heat dissipation of the motor by setting up two groups of parallel folded cooling pipes outside the motor, one group for heat dissipation and the other group for non-water flow as a spare replacement. During use, the group without water flow will occupy half of the space outside the motor, so that half of the space outside the motor cannot be contacted and cooled, affecting the uniform heat dissipation effect outside the motor, and there are certain limitations in use.

[0005] Therefore, it is necessary to provide a water-cooling pipe circulation heat dissipation structure for a motor to solve the above technical problems. Summary of the Invention

[0006] The object of the present invention is to provide a water-cooling pipe circulation heat dissipation structure for a motor, so as to solve the problem in the above background technology that half of the space outside the motor cannot be contacted and dissipated.

[0007] To achieve the above objectives, a water-cooling pipe circulation heat dissipation structure is designed in which the pipeline structure is segmented and modularized to ensure uniform and effective heat dissipation outside the motor and to facilitate disassembly and maintenance of the pipeline structure.

[0008] Based on the above ideas, the present invention provides the following technical solutions: a water-cooling pipe circulation heat dissipation structure of a motor, comprising a cover shell, wherein a plurality of bases arranged in a circular array are fixedly installed inside the cover shell, and a pipeline structure for water transportation is commonly arranged between the plurality of bases, and the pipeline structure comprises a plurality of U-shaped tubes and replacement tubes, and a flow channel corresponding to the positions of the U-shaped tube and the replacement tube is opened inside the base, and a control component corresponding to the position of one of the replacement tubes is provided on the cover shell; when the control component is started, it is carried out in two steps, the first step makes the control component correspond to different replacement tubes, and the second step pushes the corresponding replacement tube to move, and the moved replacement tube is connected to the flow channel and the corresponding U-shaped tube is staggered from the flow channel.

[0009] As a further solution of the present invention: the pipeline structure also includes two water pipes, the two water pipes are used for water inlet and water outlet respectively, and the two water pipes are respectively inserted into two adjacent bases.

[0010] As a further solution of the present invention: the base is provided with two through holes along the axial direction of the cover shell, the end of the U-shaped tube and the end of the replacement tube are inserted into the same through hole and the ends of the two are against each other, and the outer surfaces of both ends of the U-shaped tube, the outer surfaces of both ends of the replacement tube and the outer surface of the water pipe are all provided with openings.

[0011] As a further solution of the present invention: a notch is provided on the surface of the base close to the cover shell, the positioning tube is located in the notch, and the positioning tube can move along the axial direction of the cover shell based on the notch.

[0012] As a further solution of the present invention: the control component includes a support rod and a ring gear movably mounted on the cover housing, the end of the support rod is fixedly mounted with a gear that is transmission-connected to the ring gear, the outer surface of the support rod is movably sleeved with a retaining frame that movably engages with the ring gear, and the surface of the ring gear is fixedly mounted with a push plate corresponding to the position of the compensation tube.

[0013] As a further solution of the present invention: an annular groove is provided on the inner wall of the gear ring for sliding engagement with the retaining frame, and the support rod and the gear ring can both rotate based on the cover shell and slide along the axial direction of the cover shell.

[0014] As a further solution of the present invention: a guide sleeve is fixedly installed on the surface of the base away from the compensation tube, and the guide sleeve is trumpet-shaped and corresponds to the position of the through hole; when the U-shaped tube or water pipe is assembled on the base, the outer surface of the U-shaped tube or water pipe can be located in the guide sleeve.

[0015] As a further solution of the present invention: the U-shaped tube and the water pipe are both provided with movable components at the corresponding openings, and the movable components are used to block the openings; when the U-shaped tube or the water pipe is assembled on the base, the movable components are separated from the openings.

[0016] As a further solution of the present invention: the moving component includes a connecting rod slidably installed on a U-shaped tube or a water pipe, a baffle corresponding to the opening position is fixedly installed on the end of the connecting rod, and a first spring is fixedly installed on the surface of the baffle away from the opening, and the first spring makes the baffle tend to move toward the opening direction.

[0017] As a further solution of the present invention: the connecting rod is designed to be L-shaped and slides along the radial direction of the U-shaped tube or water pipe. When the connecting rod contacts the inner wall of the guide sleeve, the connecting rod slides into the U-shaped tube or water pipe to an extreme position.

[0018] Compared with existing technologies, the present invention offers the following advantages: through the coordination of the U-shaped tubes, the positioning tubes, the base, and the control assembly, a multi-tube array is formed, which can be evenly distributed outside the motor, thereby achieving uniform and effective contact with the motor's outer surface, thereby improving heat dissipation from the motor. Furthermore, the piping structure can be quickly repaired and replaced without dismantling the entire structure; only the corresponding U-shaped tube needs to be replaced. This also eliminates the need to interrupt the water supply during replacement, ensuring stable heat dissipation from the motor.

[0019] At the same time, the adaptability of the pipeline structure is improved through the design of the U-shaped tube, water pipe and base. The U-shaped tube can form a modular design, so that multiple U-shaped tubes can be replaced accordingly, and the control component can quickly correspond to the replacement tubes in different positions, making the overall disassembly and assembly convenient and more efficient; the number of U-shaped tubes installed can also be increased or decreased accordingly. At this time, the connection between the replacement tube and the flow channel can still ensure the water circulation effect and the stability of water inlet and outlet. By changing the number of U-shaped tubes, it can be suitable for use with motors of different speeds, thereby improving the applicability of the heat dissipation structure.

DETAILED DESCRIPTION

[0032] Example

[0033] See also Figures 1 to 5 The present invention provides a water-cooling pipe circulation heat dissipation structure for a motor. The structure is suitable for motors with smooth outer surfaces or motors with cooling fins on their outer surfaces. The structure is primarily used to ensure uniform and effective contact between the pipe structure 2 and the motor. Specifically, the structure includes a housing 1, within which are fixedly mounted a plurality of bases 4, on which a pipe structure 2 for water transport is disposed. During use, the pipe structure 2 contacts the motor, and water flows sequentially between the pipe structure 2 and the bases 4, thereby removing heat from the motor and achieving a heat dissipation effect.

[0034] Furthermore, the pipeline structure 2 includes a plurality of U-shaped tubes 201 and replacement tubes 202, and a flow channel 401 corresponding to the positions of the U-shaped tube 201 and the replacement tube 202 is opened inside the base 4; specifically, a plurality of bases 4, a plurality of U-shaped tubes 201 and a plurality of replacement tubes 202 are arranged in a circular array along the circumferential direction of the cover shell 1, and the two ends of the replacement tube 202 and the two ends of the U-shaped tube 201 are respectively inserted into two adjacent bases 4. Under normal conditions, the flow channel 401 corresponds to the U-shaped tube 201, and the replacement tube 202 is staggered with the flow channel 401. At this time, water flows along the U-shaped tube 201 and the flow channel 401, and a plurality of U-shaped tubes 201 can form uniform and effective contact with the outer surface of the motor, thereby effectively improving the heat dissipation effect of the motor.

[0035] Furthermore, a control component 3 corresponding to the position of one of the re-positioning tubes 202 is provided on the cover shell 1. The activation of the control component 3 is carried out in two steps. The first step can change the corresponding re-positioning tube 202, and the second step can push the re-positioning tube 202 to move, so that the re-positioning tube 202 is connected to the flow channel 401 and the corresponding U-shaped tube 201 is staggered from the flow channel 401; at this time, the U-shaped tube 201 staggered from the flow channel 401 can be quickly removed, and the re-positioning tube 202 can meet the effect of water circulation. Due to the multiple and array design of the U-shaped tubes 201, the disassembly and maintenance of the U-shaped tubes 201 are more convenient.

[0036] Reference Figure 2 and Figure 3 In this embodiment, preferably, the pipeline structure 2 also includes two water pipes 203, which are used for water inlet and outlet, respectively. The two water pipes 203 are structurally the same as the U-shaped tube 201, except that there is no U-shaped bend between them to form a connection. The water pipe 203, the U-shaped tube 201, and the replacement tube 202 are all inserted into the base 4. Under normal conditions, the water pipe 203 and the U-shaped tube 201 are connected to the flow channel 401, while the replacement tube 202 is staggered. When the replacement tube 202 is driven by the control component 3 to connect to the flow channel 401, the position of the water pipe 203 remains unchanged, and it is connected to the flow channel 401 together with the replacement tube 202, and one of the U-shaped tubes 201 is staggered. Through the above design, when one of the U-shaped tubes 201 has a problem and needs to be replaced, the problematic U-shaped tube 201 can be removed without stopping the water supply of the pipeline structure 2, thereby ensuring a stable heat dissipation effect for the motor.

[0037] Further, refer to Figure 5 The base 4 is provided with two through holes 402 along the axial direction of the housing 1. The end of the U-shaped tube 201 is inserted into one of the through holes 402. The end of the offset tube 202 is also inserted into the through hole 402 and abuts against the end of the U-shaped tube 201. When the U-shaped tube 201 is inserted into the base 4, it pushes the offset tube 202 to move along the through hole 402, thereby forming a state in which the U-shaped tube 201 is connected to the flow channel 401 while the offset tube 202 is offset. When the offset tube 202 is pushed by the control assembly 3 to connect to the flow channel 401, it pushes the U-shaped tube 201 to offset the flow channel 401. At this time, the end of the U-shaped tube 201 is still partially engaged with the housing 1 and will not fall off.

[0038] Specifically, openings are provided on the outer surfaces of both ends of the U-shaped tube 201, the outer surfaces of both ends of the repositioning tube 202, and the outer surface of the water pipe 203 to facilitate water circulation. Furthermore, the two openings of the U-shaped tube 201 are located on opposite sides of the ends, and the two openings of the repositioning tube 202 are also located on opposite sides of the ends. When the U-shaped tube 201 and the repositioning tube 202 are assembled on the base 4, their openings correspond to the flow channel 401, thereby ensuring stable water delivery.

[0039] It can be understood that a sealing ring (not shown in the figure) is fixedly embedded in the interior of the through hole 402. When the opening of the U-shaped tube 201 corresponds to the through hole 402 and the opening of the replacement tube 202 corresponds to the through hole 402, the sealing effect is ensured by the sealing ring on both the front and rear sides of the opening, and the frictional contact between the sealing ring and the U-shaped tube 201 and the replacement tube 202 also has a limiting effect on the U-shaped tube 201 and the replacement tube 202, thereby preventing the U-shaped tube 201 and the replacement tube 202 from falling off from the base 4 after water is passed.

[0040] At the same time, a notch 403 is provided on the surface of the base 4 close to the cover shell 1, and the positioning tube 202 is located in the notch 403, so that the control component 3 has space to drive the positioning tube 202 to move, and also so that when the U-shaped tube 201 is assembled on the base 4, it has space to drive the positioning tube 202 to move and be staggered with the flow channel 401.

[0041] Reference Figures 2 to 4 In this embodiment, the control assembly 3 preferably includes a support rod 301 and a ring gear 302 movably mounted on the housing 1. A gear 303, which is in transmission connection with the ring gear 302, is fixedly mounted on the end of the support rod 301. A retainer 304, which is movably sleeved on the outer surface of the support rod 301 and movably engages with the ring gear 302, is movably mounted. When the support rod 301 is rotated, the gear 303 drives the ring gear 302 to rotate along the inner wall of the housing 1, and the retainer 304 slides along the inner wall of the ring gear 302. When the support rod 301 is pushed into the housing 1, the retainer 304 drives the ring gear 302 to move synchronously, and the retainer 304 moves along the axial direction of the housing 1 toward the positioning tube 202.

[0042] Furthermore, a push plate 305 is fixedly mounted on the surface of the ring gear 302 away from the support rod 301. The push plate 305 corresponds to the position of the repositioning tube 202. When the ring gear 302 rotates along the inner wall of the housing 1, it drives the push plate 305 to move. During the movement, the push plate 305 can correspond to the repositioning tube 202 at different positions. When the ring gear 302 moves toward the repositioning tube 202, the push plate 305 can push the repositioning tube 202 into the through hole 402, and finally, the repositioning tube 202 can be in fluid communication with the flow channel 401, and the U-shaped tube 201 becomes staggered.

[0043] Specifically, the inner wall of the ring gear 302 may be provided with an annular groove (not shown in the figure), and the retaining frame 304 may rotate along the outer surface of the support rod 301. The rotation of the support rod 301 will not interfere with the retaining frame 304. The support rod 301 and the cover shell 1 are in a rotatable and slidable arrangement.

[0044] During use, water enters one of the water pipes 203, and the water flows along the flow channel 401 and the U-shaped tube 201 into the flow channel 401 of the next base 4, and finally reaches the other water pipe 203 and flows out during the flow process. The array arrangement of the U-shaped tubes 201 improves the heat dissipation effect on the motor. When one of the U-shaped tubes 201 needs to be disassembled, the rotating support rod 301 drives the gear ring 302 and the push plate 305 to move through the gear 303, so that the push plate 305 moves to the position of the replacement tube 202 corresponding to the U-shaped tube 201, and then pushes the support rod 301 into the cover 1, and drives the replacement tube 202 to move into the through hole 402 through the retaining frame 304, the gear ring 302 and the push plate 305. When moving, the replacement tube 202 can push the U-shaped tube 201 out of the through hole 402, so that the replacement tube 202 is connected to the flow channel 401 and the U-shaped tube 201 is staggered with the flow channel 401.

[0045] In summary, the coordinated design of the U-shaped tubes 201, the positioning tubes 202, the base 4, and the gear ring 302 creates an array of multiple U-shaped tubes 201 that are evenly distributed outside the motor, thereby achieving uniform and effective contact with the motor's outer surface, thereby improving heat dissipation from the motor. This also allows for rapid maintenance and replacement of the piping structure 2, eliminating the need to remove the entire piping structure 2. Simply replacing the corresponding U-shaped tube 201 is sufficient, and replacement does not require interrupting the water supply, ensuring stable heat dissipation from the motor.

[0046] At the same time, the design of the U-shaped tube 201, the water pipe 203 and the base 4 improves the adaptability of the pipeline structure 2. Multiple U-shaped tubes 201 can be replaced accordingly, and the installation position of the water pipe 203 can be freely adjusted, so that the water pipe 203 can quickly correspond to and connect with external water sources at different positions, reducing the trouble when connecting the water pipe 203 with the external water source.

[0047] In addition, the modular design of the U-shaped tube 201 can improve the overall disassembly and assembly efficiency. The rotation of the support rod 301 allows the push plate 305 to quickly correspond to the replacement tube 202 in different positions, making the overall disassembly and assembly convenient and more efficient. The number of U-shaped tubes 201 installed can also be increased or decreased accordingly. At this time, the replacement tube 202 is connected to the flow channel 401 to ensure the water circulation effect and the stability of water inlet and outlet. By changing the number of U-shaped tubes 201, it can be suitable for use with motors of different speeds, thereby improving the applicability of the heat dissipation structure.

[0048] Example

[0049] See also Figures 1 to 8On the basis of Example 1, considering that the U-shaped tube 201 is staggered with the flow channel 401 and its opening is in an exposed state during the process of disassembling and assembling the U-shaped tube 201, the cooling water in the U-shaped tube 201 will flow out into the cover 1 during the process of disassembling the U-shaped tube 201; during the process of installing the U-shaped tube 201, the opening is also partially overlapped with the flow channel 401 and the outside. At this time, the cooling water in the flow channel 401 will also flow out into the cover 1 through the opening, resulting in a waste of coolant resources.

[0050] To this end, a guide sleeve 5 is fixedly mounted on the surface of the base 4 away from the repositioning tube 202. The guide sleeve 5 is designed in a trumpet shape and corresponds to the position of the through hole 402. It has an opening portion and a vertical portion. When the U-shaped tube 201 or water pipe 203 is inserted into the base 4, the opening portion of the guide sleeve 5 allows it to be quickly inserted into the base 4 and assembled, reducing the difficulty of aligning the U-shaped tube 201 or water pipe 203 with the through hole 402. The effect is even better when it is suitable for U-shaped tubes 201 or water pipes 203 of larger lengths. The trumpet-shaped design of the guide sleeve 5 also provides effective support for the U-shaped tube 201 when the repositioning tube 202 pushes the U-shaped tube 201 out of the base 4, further preventing the U-shaped tube 201 from falling off the base 4 after removal.

[0051] Furthermore, a movable component 6 is provided at the corresponding openings of the U-shaped tube 201 and the water pipe 203. When the U-shaped tube 201 and the water pipe 203 are not assembled on the base 4, the movable component 6 can extend from the U-shaped tube 201 or the water pipe 203 and block the opening of the U-shaped tube 201 or the water pipe 203, thereby preventing the cooling water from flowing out of the opening; when the U-shaped tube 201 and the water pipe 203 are assembled on the base 4, the movable component 6 can contact the trumpet-shaped guide sleeve 5, and at this time the movable component 6 can be retracted into the U-shaped tube 201 or the water pipe 203 and the blockage of the opening is released.

[0052] Reference Figures 6 to 8 In this embodiment, preferably, the moving component 6 includes a connecting rod 601 slidably mounted on the U-shaped tube 201 or the water pipe 203. The connecting rod 601 is L-shaped and slides along the radial direction of the U-shaped tube 201 or the water pipe 203. A baffle 602 corresponding to the opening position is fixedly mounted at the end of the connecting rod 601. A first spring 603 is fixedly mounted between the baffle 602 and the inner wall of the U-shaped tube 201 or the water pipe 203. The first spring 603 makes the baffle 602 tend to move toward the opening direction, thereby making the connecting rod 601 tend to extend from the U-shaped tube 201 or the water pipe 203.

[0053] When the U-shaped tube 201 or water pipe 203 is assembled with the base 4, the connecting rod 601 can contact the trumpet-shaped opening of the guide sleeve 5 and gradually retract into the U-shaped tube 201 or water pipe 203. The connecting rod 601 can drive the baffle 602 to move synchronously and then contact and block the opening. When the U-shaped tube 201 or water pipe 203 is removed from the base 4, the vertical portion of the guide sleeve 5 can also block the opening, so that even if the baffle 602 does not contact and block the opening, the cooling water can be prevented from flowing out.

[0054] In the above structure, before the opening separates from the vertical portion of the guide sleeve 5, the connecting rod 601 can be disengaged from the trumpet-shaped opening of the guide sleeve 5, so that the baffle 602 can contact and block the opening before the opening separates from the vertical portion of the guide sleeve 5. It should be noted that the connecting rod 601 has a limit state due to the contraction of the U-shaped tube 201 or the water pipe 203, and will not slide further into the U-shaped tube 201 or the water pipe 203 due to the flow of water, thereby preventing the cooling water from flowing out of the opening corresponding to the connecting rod 601.

[0055] During use, the modular design of the U-shaped tube 201, the replacement tube 202, and the base 4 are coordinated to form a U-shaped tube 201, which can ensure heat dissipation and quick assembly and disassembly. The working process and effect of this part are the same as those in Example 1 and will not be repeated here. The difference is that when the U-shaped tube 201 or the water pipe 203 is assembled to the base 4, the connecting rod 601 can contact the guide sleeve 5 and push the connecting rod 601. At this time, the connecting rod 601 drives the baffle 602 to separate from the opening and release the blockage of the opening. At this time, the opening can enter the vertical portion of the guide sleeve 5. Even if the opening portion is connected to the flow channel 401, no cooling water will flow out. When the U-shaped tube 201 or the water pipe 203 is removed from the base 4, the vertical portion of the guide sleeve 5 can first replace the baffle 602 to achieve the blocking effect on the opening. Then the connecting rod 601 separates from the guide sleeve 5, allowing the baffle 602 to resume contact with the opening, thereby continuing the blocking effect on the opening.

[0056] Compared with the first embodiment, through the cooperation of structures such as the base 4, the U-shaped tube 201, the guide sleeve 5 and the baffle 602, during the disassembly and assembly of the U-shaped tube 201 and the water pipe 203, the vertical part of the guide sleeve 5 can serve the purpose of sealing the opening to prevent the cooling water from spilling out, and after the U-shaped tube 201 and the water pipe 203 are separated from the guide sleeve 5, the baffle 602 can contact the opening to seal the opening, further preventing the cooling water from spilling out, thereby avoiding the waste of coolant resources.

[0057] At the same time, the trumpet-shaped opening of the guide sleeve 5 is used to guide the movement of the connecting rod 601 on the one hand, and on the other hand it can facilitate the positioning of the U-shaped tube 201 and the water pipe 203 with the through hole 402, so that the U-shaped tube 201 and the water pipe 203 can be quickly installed on the base 4, reducing the trouble of alignment of the U-shaped tube 201 and the water pipe 203 during installation, and facilitating the rapid disassembly and assembly of the U-shaped tube 201 and the water pipe 203.

[0058] In addition, the guide sleeve 5 can also support the U-shaped tube 201 and the water pipe 203, so that the U-shaped tube 201 will not fall off the base 4 due to gravity when it is offset from the flow channel 401 and exits from the base 4. At this time, the size limit of the base 4 is reduced, and it can be further suitable for use with U-shaped tubes 201 and water pipes 203 with larger lengths.

[0059] Example

[0060] See also Figures 1 to 10 Based on the second embodiment, to ensure that the opening of the U-shaped tube 201 accurately corresponds to the flow channel 401 when the U-shaped tube 201 is installed in the base 4, side panels 7 can be provided on both sides of the base 4. The side panels 7 correspond to the surface of the repositioning tube 202 away from the U-shaped tube 201. When the U-shaped tube 201 is inserted into the base 4, the repositioning tube 202 is pushed out of the through hole 402. When the repositioning tube 202 abuts the side panels 7, the U-shaped tube 201 cannot move further. At this time, the opening of the U-shaped tube 201 effectively corresponds to the flow channel 401.

[0061] Furthermore, to ensure that the quick assembly and disassembly of the positioning tube 202 is not affected, the side plate 7 is slidably fitted with the base 4, and a second spring 8 is fixedly mounted between the side plate 7 and the base 4. The second spring 8 forces the side plate 7 to move outward from the base 4. When the positioning tube 202 is assembled with the base 4, the side plate 7 is pushed to slide along the base 4 and compress the second spring 8. When the positioning tube 202 is inserted into the through hole 402 in correspondence with the through hole 402, the side plate 7 is reset under the action of the second spring 8, and the side plate 7 returns to a state corresponding to the front and back of the positioning tube 202.

[0062] During use, the modular design of the U-shaped tube 201 is formed by the coordination of the U-shaped tube 201, the positioning tube 202, and the base 4, thereby ensuring heat dissipation and quick assembly and disassembly. The coordination of the base 4, the U-shaped tube 201, and the guide sleeve 5 allows the guide sleeve 5 to block the opening and support the U-shaped tube 201. The working process and effect of this part are the same as those in the second embodiment and will not be repeated here. The difference is that when the U-shaped tube 201 is assembled to the base 4, it can push the positioning tube 202 to move toward the side plate 7. When the positioning tube 202 and the side plate 7 are abutted, the opening of the U-shaped tube 201 corresponds to the flow channel 401. When the positioning tube 202 is assembled to the base 4, it can push the side plate 7 to slide along the base 4. When the positioning tube 202 corresponds to the through hole 402, it can be inserted into the through hole 402. At this time, the side plate 7 is reset under the action of the second spring 8, and the front-to-back correspondence with the positioning tube 202 ensures the limiting effect.

[0063] Compared to the second embodiment, the coordination of the base 4, the positioning tube 202, the side plate 7, and the second spring 8 facilitates the positioning of the U-shaped tube 201 during installation on the base 4, ensuring that the opening of the U-shaped tube 201 accurately aligns with the flow channel 401, thereby ensuring efficient cooling water delivery. This also prevents the positioning tube 202 from withdrawing excessively from the through-hole 402, which could affect its alignment with the push plate 305. This ensures that the push plate 305 can subsequently push the positioning tube 202 forward as the ring gear 302 moves, further facilitating accurate alignment of the positioning tube 202 opening with the flow channel 401.
