Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation, and particularly relates to a water-cooled pipe circulation heat dissipation structure for a motor. Background Art

[0002] The heat dissipation methods of motors are divided into various types according to different cooling media, heat transfer mechanisms and application products. The core is to control the motor temperature rise, extend the service life and improve the power density. Some existing motors are provided with pipes outside the motor housing to convey cooling water, and the heat is carried away during the circulation of the cooling water.

[0003] For example, Chinese Patent Publication No. CN119134790A discloses a water-cooled permanent magnet motor, which relates to the technical field of permanent magnet motor assembly. It includes a permanent magnet motor body with a plurality of pipe grooves on the periphery, a cooling pipe one and a cooling pipe two which are arranged in a segmented and folded manner and the folding parts are alternately inserted into the pipe grooves; the cooling pipe limiting mechanism includes an outer support housing installed outside the permanent magnet motor body, and a limiting component for limiting the cooling pipe one and the cooling pipe two; the on-off switching mechanism includes a bracket fixedly installed on the outer support housing, an outer connecting pipe frame arranged on the bracket, and an on-off switching component; the on-off switching component is used to control the on-off between the liquid inlet pipe and the liquid outlet pipe and the connector one or the connector two. When replacing the cooling pipe, it is not necessary to disassemble the permanent magnet motor body, and the cooling pipe can be replaced without stopping the permanent magnet motor. When one set of the cooling pipe one or the cooling pipe two is removed, the other set of cooling pipes can still work normally to cool the permanent magnet motor body.

[0004] This application realizes the heat dissipation of the motor by setting two sets of juxtaposed and folded cooling pipes outside the motor. One set conducts water for heat dissipation and the other set does not conduct water for standby replacement. During use, the set that does not conduct water will occupy half of the space outside the motor, so that there is always half of the space outside the motor that cannot be in contact with heat dissipation, 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-cooled pipe circulation heat dissipation structure for a motor to solve the above technical problems. Summary of the Invention

[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 replacement tube is located in the notch, and the replacement tube can move along the axial direction of the cover shell based on the notch.

[0013] As a further solution of the present invention: an annular groove which is slidably matched with the retaining frame is formed on the inner wall of the gear ring, 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, the guide sleeve is designed in a trumpet shape 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: movable components are provided at the corresponding openings of the U-shaped tube and the water pipe, 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.

At this time, when the compensating pipe is connected to the flow channel, the water flow effect can still be ensured, and the stability of water inlet and outlet can be guaranteed. By changing the number of U-shaped pipes, it is applicable to motors with different speeds, and thus the applicability of the heat dissipation structure is improved.

Detailed implementation manners Embodiment

[0022] Please refer to Figures 1 to 5 , an embodiment of the present invention provides a water-cooled pipe circulation heat dissipation structure for a motor, which is applicable to motors with a smooth outer surface and motors with cooling fins on the outer surface, and is mainly used to ensure uniform and effective contact between the pipeline structure 2 and the motor. Specifically, it includes a housing 1, and a plurality of bases 4 are fixedly installed inside the housing 1, and a pipeline structure 2 for water delivery is provided on the plurality of bases 4 together; during use, the pipeline structure 2 contacts the motor, and water flows sequentially between the pipeline structure 2 and the plurality of bases 4, thereby taking away the heat of the motor to achieve a heat dissipation effect.

[0023] Furthermore, the pipeline structure 2 includes a plurality of U-shaped pipes 201 and compensation pipes 202, and a flow channel 401 corresponding to the positions of both the U-shaped pipes 201 and the compensation pipes 202 is opened inside the housing 1; specifically, the plurality of bases 4, the plurality of U-shaped pipes 201, and the plurality of compensation pipes 202 are all arranged in a circumferential direction of the housing 1 in a circular array, and both ends of the compensation pipes 202 and both ends of the U-shaped pipes 201 are respectively inserted into two adjacent bases 4. In a normal state, the flow channel 401 corresponds to the U-shaped pipes 201, and the compensation pipes 202 are staggered from the flow channel 401. At this time, water flows along the U-shaped pipes 201 and the flow channel 401, and the plurality of U-shaped pipes 201 can form uniform and effective contact with the outer surface of the motor, thereby effectively improving the heat dissipation effect on the motor.

[0024] Furthermore, a control component 3 corresponding to the position of one of the replacement tubes 202 is provided on the cover shell 1. The control component 3 is activated in two steps. The first step can change the corresponding replacement tube 202, and the second step can push the replacement tube 202 to move, so that the replacement 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 replacement tube 202 can meet the effect of water circulation. Due to the multiple and array design of the U-shaped tube 201, the disassembly and maintenance of the U-shaped tube 201 are more convenient.

[0025] Reference Figure 2 and Figure 3 In this embodiment, it is preferred that: the pipeline structure 2 also includes two water pipes 203, the two water pipes 203 are used for water inlet and water outlet respectively, and the two water pipes 203 are structurally the same as the U-shaped tube 201, except that there is no U-shaped bend between the two to form a connection. Among them, the water pipe 203, the U-shaped tube 201 and the replacement tube 202 are all inserted into the base 4, and 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, which can ensure the stable heat dissipation effect of the motor.

[0026] Further, see 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, and the end of the position-replacing 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, the position-replacing tube 202 can be pushed 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 and the position-replacing tube 202 is staggered. When the position-replacing tube 202 is pushed by the control component 3 to connect to the flow channel 401, the U-shaped tube 201 can be pushed to stagger with 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.

[0027] Specifically, the outer surfaces of both ends of the U-shaped tube 201, the outer surfaces of both ends of the replacement tube 202, and the outer surface of the water pipe 203 are all provided with openings for realizing the circulation of water. Moreover, the two openings of the U-shaped tube 201 are located on the opposite sides of the two ends, and the two openings of the replacement tube 202 are also located on the opposite sides of the two ends, so that after the U-shaped tube 201 and the replacement tube 202 are assembled on the base 4, the openings can correspond to the flow channel 401, thereby ensuring the stable transportation of water.

[0028] It can be understood that a sealing ring (not shown in the figure) is fixedly embedded inside 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. 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.

[0029] 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 makes the U-shaped tube 201 have space to drive the positioning tube 202 to move and stagger with the flow channel 401 when it is assembled on the base 4.

[0030] Reference Figures 2 to 4 In this embodiment, preferably: the control assembly 3 includes a support rod 301 and a gear ring 302 movably mounted on the housing 1, a gear 303 connected to the gear ring 302 is fixedly mounted on the end of the support rod 301, and a retainer 304 movably engaged with the gear ring 302 is movably sleeved on the outer surface of the support rod 301. When the support rod 301 is rotated, the gear ring 302 can be driven to rotate along the inner wall of the housing 1 through the gear 303, and the retainer 304 can slide along the inner wall of the gear ring 302; when the support rod 301 is pushed into the housing 1, the gear ring 302 can be driven to move synchronously through the retainer 304, and the retainer 304 moves toward the position-replacing tube 202 along the axial direction of the housing 1.

[0031] Furthermore, a push plate 305 is fixedly mounted on the surface of the gear ring 302 away from the support rod 301, and the push plate 305 corresponds to the position of the replacement tube 202. When the gear ring 302 rotates along the inner wall of the housing 1, the push plate 305 can be driven to move, and the push plate 305 can correspond to the replacement tube 202 at different positions during the movement. When the gear ring 302 moves toward the replacement tube 202, the push plate 305 can push the replacement tube 202 to move into the through hole 402, and finally the replacement tube 202 can form a flow with the flow channel 401 and the U-shaped tube 201 is staggered.

[0032] Specifically, the inner wall of the gear ring 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 placement state.

[0033] When in use, water enters one of the water pipes 203, and the water enters the flow channel 401 of the next base 4 along the flow channel 401 and the U-shaped tube 201, and finally reaches the other water pipe 203 and flows out during the flow process. The array arrangement of the U-shaped tubes 201 makes the heat dissipation effect of the motor better. 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 housing 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 the replacement tube 202 moves, it 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 from the flow channel 401.

[0034] In summary, through the cooperation of the U-shaped tube 201, the replacement tube 202, the base 4 and the gear ring 302, the array design of multiple U-shaped tubes 201 can be evenly arranged outside the motor, thereby forming a uniform and effective contact with the outer surface of the motor to improve the heat dissipation effect of the motor. And the pipeline structure 2 can be quickly repaired and replaced without removing the pipeline structure 2 as a whole, and only the corresponding U-shaped tube 201 needs to be replaced, and there is no need to stop the water supply during replacement, which can ensure the stable heat dissipation effect of the motor.

[0035] At the same time, the adaptability of the pipeline structure 2 is improved through the design of the U-shaped tube 201, the water pipe 203 and the base 4. 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.

[0036] 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, and the overall disassembly and assembly is convenient and more efficient. The number of U-shaped tubes 201 can also be increased or decreased accordingly. At this time, the connection between the replacement tube 202 and the flow channel 401 can 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. Example

[0037] See also Figures 1 to 8, on the basis of the first embodiment, considering that when the U-shaped tube 201 is staggered from the flow channel 401 and during the process of disassembling and assembling the U-shaped tube 201, its opening is in an exposed state, so that during the removal of the U-shaped tube 201, the cooling water in the U-shaped tube 201 will flow out into the housing 1; during the installation of the U-shaped tube 201, the opening is also partially overlapped with the flow channel 401 and the outside, and at this time, the cooling water in the flow channel 401 will also flow out into the housing 1 through the opening, resulting in waste of coolant resources.

[0038] Therefore, a guide sleeve 5 is fixedly installed on the surface of the base 4 away from the compensation pipe 202. The guide sleeve 5 is designed in a horn shape and corresponds to the position of the through hole 402, and it has an opening part and a vertical part. When the U-shaped tube 201 or the water pipe 203 is inserted into the base 4, due to the design of the opening part of the guide sleeve 5, it can be quickly inserted into the base 4 to complete the assembly, reducing the trouble of corresponding the U-shaped tube 201 or the water pipe 203 with the through hole 402, and it has a better effect when applicable to the U-shaped tube 201 or the water pipe 203 with a larger length dimension. Through the horn-shaped guide sleeve 5, when the compensation pipe 202 pushes the U-shaped tube 201 out of the base 4, it can also provide effective support for the U-shaped tube 201, further avoiding the U-shaped tube 201 falling off the base 4 after being removed.

[0039] Furthermore, moving components 6 are arranged 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 onto the base 4, the moving components 6 can extend from the U-shaped tube 201 or the water pipe 203 and block the openings of the U-shaped tube 201 or the water pipe 203, thereby avoiding the outflow of cooling water from the openings; after the U-shaped tube 201 and the water pipe 203 are assembled onto the base 4, the moving components 6 can contact the horn-shaped guide sleeve 5, and at this time, the moving components 6 can be retracted into the U-shaped tube 201 or the water pipe 203 and release the blockage of the openings.

[0040] Refer to Figures 6 to 8 , in this embodiment, preferably: the moving component 6 includes a connecting rod 601 slidably installed on the U-shaped tube 201 or the water pipe 203. The connecting rod 601 is designed in an L shape 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 installed at the end of the connecting rod 601. A first spring 603 is fixedly installed 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 towards the opening direction, thereby making the connecting rod 601 tend to extend from the U-shaped tube 201 or the water pipe 203.

[0041] When the U-shaped tube 201 or the water pipe 203 is assembled to the base 4, the connecting rod 601 can contact the trumpet-shaped opening of the guide sleeve 5 and gradually shrink into the U-shaped tube 201 or the water pipe 203, and the connecting rod 601 can drive the baffle 602 to move synchronously and then contact the opening to block it. When the U-shaped tube 201 or the water pipe 203 is removed from the base 4, the vertical part of the guide sleeve 5 can also block the opening, so that even if the baffle 602 does not contact the opening to form a blockage, the effect of cooling water flowing out can be avoided.

[0042] In the above structure, before the opening is separated from the vertical part of the guide sleeve 5, the connecting rod 601 can be separated from the trumpet-shaped opening of the guide sleeve 5, so that before the opening is separated from the vertical part of the guide sleeve 5, the baffle 602 can be in contact with the opening to form a blockage. It should be noted that the connecting rod 601 has a limit state based on the contraction of the U-shaped tube 201 or the water pipe 203, and the connecting rod 601 will not slide further into the U-shaped tube 201 or the water pipe 203 due to the water flow, so as to prevent the cooling water from flowing out from the opening corresponding to the connecting rod 601.

[0043] When in use, the U-shaped tube 201 with modular design can ensure heat dissipation effect and quick disassembly and assembly through the cooperation of the U-shaped tube 201, the replacement tube 202 and the base 4. The working process and effect of this part are the same as those in the first embodiment, 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 with 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 to release the blockage of the opening. At this time, the opening can enter the vertical part of the guide sleeve 5. Even if the opening part 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 part of the guide sleeve 5 can first replace the baffle 602 to achieve the blocking effect of the opening, and then the connecting rod 601 is separated from the guide sleeve 5 so that the baffle 602 resumes the contact state with the opening, and then the blocking effect of the opening is continued.

[0044] 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 with the opening to seal the opening, further preventing the cooling water from spilling out, thereby avoiding the waste of coolant resources.

[0045] 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 aligning the U-shaped tube 201 and the water pipe 203 during installation, which is conducive to the rapid disassembly and assembly of the U-shaped tube 201 and the water pipe 203.

[0046] In addition, the guide sleeve 5 can also support the U-shaped tube 201 and the water pipe 203, so that when the U-shaped tube 201 is offset from the flow channel 401 and withdraws from the base 4, it will not fall off the base 4 due to gravity. At this time, the size restriction on 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. Example

[0047] See also Figures 1 to 10 On the basis of the second embodiment, considering that the opening of the U-shaped tube 201 accurately corresponds to the flow channel 401 when the U-shaped tube 201 is installed on the base 4, side plates 7 can be provided on both sides of the base 4, and the side plates 7 correspond to the surface of the replacement tube 202 away from the U-shaped tube 201. When the U-shaped tube 201 is inserted into the base 4, the replacement tube 202 can be pushed out of the through hole 402. When the replacement tube 202 abuts against the side plates 7, the U-shaped tube 201 can no longer move. At this time, the opening of the U-shaped tube 201 effectively corresponds to the flow channel 401.

[0048] Furthermore, in order not to affect the rapid disassembly and assembly of the replacement tube 202, the side plate 7 and the base 4 are slidably matched, and a second spring 8 is fixedly installed between the side plate 7 and the base 4, and the second spring 8 makes the side plate 7 have a tendency to move toward the outside of the base 4. When the replacement tube 202 is assembled to the base 4, the side plate 7 can be pushed to slide along the base 4 and squeeze the second spring 8. When the replacement tube 202 is inserted into the through hole 402 corresponding to the through hole 402, the side plate 7 can be 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 replacement tube 202.

[0049] In use, through the cooperation of structures such as the U-shaped tube 201, the compensating tube 202, and the base 4, the modularly designed U-shaped tube 201 can ensure the heat dissipation effect and rapid disassembly and assembly; through the cooperation of structures such as the base 4, the U-shaped tube 201, and the guide sleeve 5, the guide sleeve 5 can play the role of blocking the opening and supporting 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 compensating tube 202 to move towards the side plate 7. When the compensating tube 202 abuts against the side plate 7, the opening of the U-shaped tube 201 corresponds to the flow channel 401; when the compensating tube 202 is assembled to the base 4, it can push the side plate 7 to slide along the base 4. When the compensating 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 is in front-to-back correspondence with the compensating tube 202 to ensure the limiting effect.

[0050] Compared with the second embodiment, through the cooperation of structures such as the base 4, the compensating tube 202, the side plate 7, and the second spring 8, it is convenient to position the U-shaped tube 201 when it is installed on the base 4, ensure the accurate correspondence between the opening of the U-shaped tube 201 and the flow channel 401, and thus ensure the cooling water delivery effect. At the same time, it can also prevent the compensating tube 202 from withdrawing too much from the through hole 402, affecting the corresponding state with the push plate 305, ensure that the subsequent movement of the push plate 305 along with the gear ring 302 can smoothly push the compensating tube 202 to move, and thus is also beneficial to ensuring the accurate correspondence between the opening of the compensating tube 202 and the flow channel 401.
