Description

Technical Field

[0001] The present application relates to the technical field of water-cooled motors, and in particular to a water-cooled motor with a shielding device. Background Art

[0002] A water-cooled motor generally refers to a device or mechanism that uses a water cooling system to reduce the operating temperature of the motor. This technology is usually used for motors that need to operate at high power for a long time, such as some industrial applications or the CPU or GPU of a high-performance computer. Water-cooled motors provide an efficient, low-temperature and relatively quiet cooling solution by effectively conducting heat away from the motor or electronic components.

[0003] In motor technology, water-cooled motors are widely used in various devices that require high-power continuous operation due to their efficient cooling performance. However, when the motor is operating, the magnetic field leakage problem caused by the current flowing through the winding has always been a key factor affecting the motor efficiency. Magnetic field leakage not only causes energy loss, but also limits the further improvement of motor performance. Although the traditional water-cooled motor design can solve the heat dissipation problem of the motor to a certain extent, there is still huge room for improvement in controlling magnetic field leakage. Utility Model Content

[0004] In order to reduce the leakage of the motor's magnetic field, lower the magnetic field loss, and improve the motor's operating efficiency, the present application provides a water-cooled motor with a shielding device.

[0005] The present application provides a water-cooled motor with a shielding device, which adopts the following technical solution:

[0006] A water-cooled motor with a shielding device comprises a rotor unit and a stator unit, the rotor unit comprises a steel sheet group, a latch, a coil winding and a water-cooling pipe, the steel sheet group comprises a yoke and a tooth portion, the latch is fixedly connected to the yoke portion, a groove portion is formed between adjacent teeth portions, the water-cooling pipe is distributed in the groove portion so that the water-cooling pipe is adhered to the yoke and the tooth portion, the coil winding is wound around the tooth portion, a magnetic isolation sheet is arranged between the coil winding and the water-cooling pipe, and the magnetic isolation sheet is provided with a through hole for the tooth portion to pass through so that the magnetic isolation sheet can be sleeved on the tooth portion.

[0007] By adopting the above-mentioned technical scheme, in the traditional motor design, the current passing through the coil will generate a magnetic field, and this magnetic field may leak into the surrounding environment, causing electromagnetic interference problems, especially for sensitive electronic equipment. In this water-cooled motor, the presence of the magnetic isolation sheet can effectively isolate the magnetic field between the coil winding and the water-cooling tube. The magnetic isolation sheet usually adopts a material with high magnetic permeability, such as nickel alloy or special alloy, which can absorb and guide the magnetic field to prevent it from leaking into the external environment; the leakage of the magnetic field will lead to magnetic energy loss, and these losses are manifested as reduced motor efficiency. By arranging a magnetic isolation sheet between the coil winding and the water-cooling tube, this loss can be reduced. The magnetic isolation sheet effectively controls the propagation path of the magnetic field, so that more magnetic energy can be used to drive the motor instead of being dissipated in the surrounding environment. By reducing magnetic field leakage and magnetic field loss, the overall efficiency of the motor is improved. The scheme in this application has the effect of reducing the leakage of the motor magnetic field, reducing magnetic field loss, and improving the operating efficiency of the motor.

[0008] Optionally, the water cooling pipe includes a water inlet, a heat dissipation part and a water outlet, the water inlet is parallel to the length direction of the steel sheet group so that the water inlet is parallel to the coil winding and discharges the liquid into the heat dissipation part, the heat dissipation part is used to penetrate the groove part so that the heat dissipation part presents a wavy shape, and the water outlet is connected to the heat dissipation part for discharging the liquid in the heat dissipation part.

[0009] By adopting the above technical solution, the water inlet is parallel to the length direction of the steel sheet group. This arrangement can effectively form a metal shielding area inside the motor. When the liquid enters the water cooling pipe through the water inlet, the liquid flows through the heat dissipation part near the steel sheet group. This process not only helps to dissipate heat, but also provides a metal shielding effect to a certain extent, reducing the electromagnetic radiation inside the motor and external electromagnetic interference. The heat dissipation part is penetrated in the groove of the steel sheet group and is wavy, which not only increases the heat dissipation area and improves the heat dissipation efficiency, but also helps to optimize the path and speed of water flow.

[0010] Optionally, the coil winding is sleeved with insulating paper, so that the insulating paper is spaced between the coil winding and the magnetic isolation sheet and between the coil winding and the tooth portion.

[0011] By adopting the above technical solution, the insulating paper can effectively isolate the contact between the coil winding and the magnetic isolation sheet to prevent possible electrical short circuit or breakdown. When the motor is running, the coil winding will be affected by high voltage and high frequency current. Without proper insulation protection, electrical faults may occur between the windings or between the windings and structural parts. Therefore, the insulating paper plays a key electrical isolation role here to ensure the stable operation and long-term reliability of the motor.

[0012] Optionally, the steel sheet group includes N steel sheets, wherein N is an integer greater than or equal to 1, and the N steel sheets are arranged in parallel. The pin includes a connecting portion and a limiting portion, and the length of the limiting portion is greater than that of the connecting portion so that the cross-section of the pin is T-shaped. The steel sheet is provided with a connecting groove for the connecting portion to be embedded and a limiting groove for the limiting portion to be embedded.

[0013] By adopting the above technical solution, the T-shaped cross-section of the pin can ensure a firm connection between the pin and the steel sheet, while the design of the limit portion can accurately control the position of the steel sheets and the distance between them. The design of the connecting groove and the limit groove makes the assembly of the steel sheet group easier and faster while maintaining a high assembly accuracy. If the position of the steel sheet needs to be replaced or adjusted, maintenance and adjustment can be performed relatively easily due to the design of the pin.

[0014] Optionally, a plurality of mounting holes are provided on a side of the connection portion away from the steel sheet group.

[0015] By adopting the above technical solution, the entire structure can be firmly fixed to the desired position or base through the mounting holes, thereby enhancing the stability of the overall structure. The presence of the mounting holes allows fixation at different positions and angles, thereby adapting to various assembly requirements and space limitations.

[0016] Optionally, a fixed end plate is provided on one side of the steel plate group along the width direction, a cable is provided on the side of the fixed end plate away from the steel plate group, a T-shaped block is provided on the side of the fixed end plate close to the steel plate group, and the fixed end plate is fixedly connected to the steel plate group via the T-shaped block.

[0017] By adopting the above technical solution, a cable is installed on the side of the fixed end plate away from the steel plate group, so that the motor can be electrically connected to the external device through the cable. A T-shaped block is set on the fixed end plate on the side close to the steel plate group. The fixed end plate is fixedly connected to the steel plate group through the T-shaped block. This connection method may be achieved by bolts, nuts or other fasteners to ensure a firm connection between the end plate and the steel plate group, thereby ensuring the stability and reliability of the overall structure during use.

[0018] Optionally, the stator unit includes a stator plate and a plurality of magnets spaced apart along a length direction of the stator plate, the stator plate is provided with assembly holes on both sides of the magnets, and the stator plate is installed and positioned through the assembly holes.

[0019] By adopting the above technical solution, the stator plate serves as the main supporting structure, and the magnets are arranged at intervals along the length direction of the stator plate to generate a magnetic field to perform specific electromagnetic functions. The assembly holes on the stator plate can ensure that the magnets are correctly installed and positioned at the predetermined positions, and can also ensure that the stator plate is fixed in position on the external device and connected to the external device by fasteners such as screws passing through the assembly holes.

[0020] Optionally, a cover plate for covering the magnet is disposed on the stator plate, and a positioning groove for embedding the magnet is disposed on the cover plate, and the bottom of the positioning groove is tightly pressed against the magnet.

[0021] By adopting the above technical solution, the bottom of the positioning groove is pressed against the surface of the magnet. This design ensures that the magnet is firmly fixed on the cover to prevent it from moving or loosening during use. The cover not only protects the magnet from the influence of the external environment, but also ensures the stability of the magnet through the positioning groove, so that it maintains reliability during long-term operation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. In traditional motor design, current passing through the coil will generate a magnetic field, which may leak into the surrounding environment, causing electromagnetic interference problems, especially for sensitive electronic equipment. In this water-cooled motor, the presence of a magnetic isolation sheet can effectively isolate the magnetic field between the coil winding and the water-cooling tube. The magnetic isolation sheet is usually made of a material with high magnetic permeability, such as a nickel alloy or a special alloy, which can absorb and guide the magnetic field to prevent it from leaking into the external environment. The leakage of the magnetic field will lead to magnetic energy loss, which is manifested as a reduction in motor efficiency. This loss can be reduced by arranging a magnetic isolation sheet between the coil winding and the water-cooling tube. The magnetic isolation sheet effectively controls the propagation path of the magnetic field, so that more magnetic energy can be used to drive the motor instead of being lost in the surrounding environment. By reducing magnetic field leakage and magnetic field loss, the overall efficiency of the motor is improved. The solution in this application has the effect of reducing the leakage of the motor magnetic field, reducing magnetic field loss, and improving the operating efficiency of the motor.

[0024] 2. The water inlet is parallel to the length direction of the steel sheet group. This arrangement can effectively form a metal shielding area inside the motor. When the liquid enters the water cooling tube through the water inlet, the liquid flows through the heat dissipation part near the steel sheet group. This process not only helps to dissipate heat, but also provides a metal shielding effect to a certain extent, reducing the electromagnetic radiation inside the motor and external electromagnetic interference. The heat dissipation part is arranged in the groove of the steel sheet group and presents a wave shape, which not only increases the heat dissipation area and improves the heat dissipation efficiency, but also helps to optimize the path and speed of water flow;

[0025] 3. Insulating paper can effectively isolate the contact between the coil winding and the magnetic isolation sheet to prevent possible electrical short circuit or breakdown. When the motor is running, the coil winding will be affected by high voltage and high frequency current. Without proper insulation protection, it may cause electrical faults between windings or between windings and structural parts. Therefore, insulating paper plays a key role in electrical isolation here to ensure the stable operation and long-term reliability of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] An embodiment of the present application discloses a water-cooled motor with a shielding device.

[0039] Reference Figure 1 and Figure 2A water-cooled motor with a shielding device includes a rotor unit 1 and a stator unit 2, wherein the rotor unit 1 includes a steel sheet group 3, a latch 4, a coil winding 5 and a water-cooling pipe 6, the steel sheet group 3 includes a yoke 7 and a tooth 8, and a groove 9 is formed between adjacent teeth 8. In order to improve the heat dissipation efficiency of the motor, the water-cooling pipe 6 is distributed in the groove 9 so that the water-cooling pipe 6 is attached to the yoke 7 and the tooth 8, and the coil winding 5 is wound around the tooth 8. In the traditional motor design, the current passing through the coil winding 5 will generate a magnetic field, and this magnetic field may leak To the surrounding environment, it causes electromagnetic interference problems, especially for sensitive electronic equipment. For this reason, a magnetic isolation sheet 10 is arranged between the coil winding 5 and the water-cooling tube 6. The magnetic isolation sheet 10 is provided with a through hole 11 for the tooth portion 8 to pass through, so that the magnetic isolation sheet 10 can be sleeved on the tooth portion 8. The existence of the magnetic isolation sheet 10 can effectively isolate the magnetic field between the coil winding 5 and the water-cooling tube 6. The magnetic isolation sheet 10 is usually made of a material with high magnetic permeability, such as nickel alloy or special alloy, which can absorb and guide the magnetic field, thereby preventing it from leaking to the external environment.

[0040] like Figure 3 As shown, the water-cooling pipe 6 includes a water inlet 12, a heat dissipation portion 13 and a water outlet 14. In order to further improve the shielding effect and reduce the leakage of the motor magnetic field, the water inlet 12 is parallel to the length direction of the steel sheet group 3, so that the water inlet 12 is parallel to the coil winding 5. This arrangement can effectively form a metal shielding area inside the motor. When the liquid enters the water-cooling pipe 6 through the water inlet 12, the liquid flows through the heat dissipation portion 13 near the steel sheet group 3. This process not only helps to dissipate heat, but also provides a metal shielding effect to a certain extent, reducing the electromagnetic radiation inside the motor and external electromagnetic interference; the water inlet 12 transports the liquid to the heat dissipation portion 13, and the heat dissipation portion 13 is used to penetrate the groove portion 9 so that the heat dissipation portion 13 is wavy. The heat dissipation portion 13 is penetrated in the groove portion 9 of the steel sheet group 3 and presents a wavy shape, which not only increases the heat dissipation area and improves the heat dissipation efficiency, but also helps to optimize the path and speed of water flow. The water outlet 14 is connected to the heat dissipation portion 13 to discharge the liquid that absorbs heat in the heat dissipation portion 13. It should be noted that the shielding device includes the magnetic isolation sheet 10 and the water inlet 12, which can reduce the leakage of the motor's magnetic field and reduce the magnetic field loss of the motor.

[0041] like Figure 3 and Figure 4As shown, the latch 4 is fixedly connected to the yoke 7. Specifically, the steel sheet group 3 includes N steel sheets, wherein N is an integer greater than or equal to 1, and the N steel sheets are arranged in parallel. The latch 4 includes a connecting portion 15 and a limiting portion 16. The length of the limiting portion 16 is greater than that of the connecting portion 15, so that the cross-section of the latch 4 is T-shaped. A connecting groove 17 for the connecting portion 15 to be embedded and a limiting groove 18 for the limiting portion 16 to be embedded are provided in the yoke 7 of the steel sheet. A plurality of mounting holes 19 are provided on the side of the connecting portion 15 away from the steel sheet group 3. The T-shaped cross section of the latch 4 can ensure a firm connection between the latch 4 and the steel sheet. At the same time, the design of the limiting portion 16 can accurately control the position of the steel sheets and the distance between them. The design of the connecting groove 17 and the limiting groove 18 makes the assembly of the steel sheet group 3 easier and faster, while maintaining a high assembly accuracy. If the position of the steel sheet needs to be replaced or adjusted, maintenance and adjustment can be performed relatively easily due to the design of the latch 4. The entire structure can be firmly fixed to the desired position or base through the mounting hole 19, thereby enhancing the stability of the overall structure.

[0042] In one embodiment, when the motor is running, the coil winding 5 will be affected by high voltage and high frequency current. If there is no proper insulation protection, electrical faults may occur between the coil windings 5 ​​or between the coil windings 5 ​​and the structural parts. Therefore, an insulating paper (not shown in the figure) is provided on the coil winding 5 to space the insulating paper between the coil winding 5 and the magnetic isolation plate 10 and between the coil winding 5 and the tooth portion 8. The insulating paper can effectively isolate the contact between the coil winding 5 and the magnetic isolation plate 10 to prevent electrical short circuit or breakdown. Therefore, the insulating paper plays a key electrical isolation role here to ensure the stable operation and long-term reliability of the motor.

[0043] like Figure 5 As shown, a fixed end plate 20 is installed on one side of the steel plate group 3 along the width direction, and a cable 21 is installed on the side of the fixed end plate 20 away from the steel plate group 3, so that the motor can be electrically connected to the external device through the cable 21, and a T-shaped block 22 is arranged on the fixed end plate 20 on the side close to the steel plate group 3, and the fixed end plate 20 is fixedly connected to the steel plate group 3 through the T-shaped block 22. This connection method may be achieved by bolts, nuts or other fixings to ensure a firm connection between the end plate and the steel plate group 3, thereby ensuring the stability and reliability of the overall structure during use.

[0044] like Figure 6As shown, the stator unit 2 includes a stator plate 23 and a plurality of magnets 24 installed at intervals along the length direction of the stator plate 23. The stator plate 23 is provided with assembly holes 25 on both sides of the magnets 24. The stator plate 23 is installed and positioned through the assembly holes 25. The stator plate 23 serves as the main supporting structure. The magnets 24 are arranged at intervals along the length direction of the stator plate 23 to generate a magnetic field to perform a specific electromagnetic function. The assembly holes 25 on the stator plate 23 can ensure that the magnets 24 are correctly installed and positioned at a predetermined position, and can also ensure that the stator plate 23 is fixed to a position on an external device, and is connected to the external device after fasteners such as screws pass through the assembly holes 25. A cover plate 26 for covering the magnet 24 is installed on the stator plate 23. A positioning groove 27 for the magnet 24 to be embedded is opened on the cover plate 26. The bottom of the positioning groove 27 is tightly pressed against the magnet 24, and the bottom of the positioning groove 27 is tightly pressed against the surface of the magnet 24. This design ensures that the magnet 24 is firmly fixed on the cover plate 26 to prevent it from moving or loosening during use. The cover plate 26 not only protects the magnet 24 from the influence of the external environment, but also ensures the stability of the magnet 24 through the positioning groove 27, so that it maintains reliability during long-term operation.

[0045] The implementation principle of a water-cooled motor with a shielding device in the embodiment of the present application is as follows: it includes a mover unit 1 and a stator unit 2, the mover unit 1 includes a steel sheet group 3, a latch 4, a coil winding 5 and a water-cooling pipe 6, the steel sheet group 3 includes a yoke 7 and a tooth 8, the latch 4 is fixedly connected to the yoke 7, a groove 9 is formed between adjacent teeth 8, the water-cooling pipe 6 is distributed in the groove 9, so that the water-cooling pipe 6 is attached to the yoke 7 and the tooth 8, and the coil winding 5 is wound around the tooth 8. In the traditional motor design, the current passing through the coil will generate a magnetic field, and this magnetic field may leak into the surrounding environment, causing electromagnetic interference problems, especially for sensitive electronic equipment, in the coil A magnetic isolation sheet 10 is arranged between the winding 5 and the water-cooling tube 6. The existence of the magnetic isolation sheet 10 can effectively isolate the magnetic field between the coil winding 5 and the water-cooling tube 6. The magnetic isolation sheet 10 is usually made of a material with high magnetic permeability, such as nickel alloy or special alloy, which can absorb and guide the magnetic field, thereby preventing it from leaking to the external environment. The magnetic isolation sheet 10 effectively controls the propagation path of the magnetic field, so that more magnetic energy can be used to drive the motor instead of being dissipated in the surrounding environment. By reducing magnetic field leakage and magnetic field loss, the overall efficiency of the motor is improved. The scheme in the present application has the effect of reducing the leakage of the motor magnetic field, reducing magnetic field loss, and improving the operating efficiency of the motor.
