Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motors, specifically a high-efficiency heat dissipation water-cooled permanent magnet motor. Background Technology

[0002] Today, automotive motors differ from power devices in other fields, requiring higher standards such as small size, light weight, high efficiency, high torque at low speeds, constant power at high speeds, and wide speed range. These requirements are designed to enhance the comfort of new energy vehicles and increase market acceptance and market share. Permanent magnet synchronous motors, with their small size, high performance, high efficiency, and high reliability, are finding increasingly widespread application in the field of new energy vehicles.

[0003] According to Chinese Patent No. CN223052848U, a low-noise water-cooled permanent magnet synchronous motor is disclosed. This utility model has a disassembly and assembly component. When it is necessary to connect the cooling coil to the external water pipe, the insert plate on the pipe body can be inserted into the slot. At the same time, the sealing ring will be locked into the sealing groove. Then, the operator can rotate the clamping ring, which moves the clamping ring and pushes the pressure rod into the groove. The pressure rod will drive the locking pin to move and stretch the spring. The locking pin will then move into the corresponding locking hole, thereby achieving the purpose of clamping and fixing the pipe body. After clamping, the clamping ring can be stopped without rotation. This method allows for quick installation of the pipe body without the need for multiple bolts for connection and fixation. Only one clamping ring needs to be rotated. The operation steps are simple and the disassembly is also relatively convenient.

[0004] Currently, the connection between cooling water pipes and external pipes is mostly achieved using flanges and bolts. During installation, flange misalignment can easily lead to misalignment of bolt holes, requiring repeated adjustments to the flange position to precisely screw the bolts in. This cumbersome operation significantly reduces the connection efficiency between the cooling water pipes and external pipes. Regarding the aforementioned patent content, although this utility model achieves the connection between the external pipe and the cooling water pipe by setting up structures such as springs, locking columns, pressure rods, and clamping rings, and the connection method is more convenient than bolts, the structure is relatively complex, inconvenient to maintain, and also has a threaded connection structure, thereby reducing the connection effect between the external pipe and the cooling water pipe. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a high-efficiency heat dissipation water-cooled permanent magnet motor to solve the technical problem of the relatively complex structure used in the existing external tube body and cold water pipe connection method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation water-cooled permanent magnet motor, including an inner shell, a cooling cavity formed on the outer wall of the inner shell, a cooling water pipe installed inside the cooling cavity, an outer shell installed on the outer wall of the inner shell, an inlet pipe extending to the outside of the outer shell connected to the inlet end of the cooling water pipe, and an outlet pipe extending to the outside of the outer shell connected to the outlet end of the cooling water pipe, a first connecting plate installed at the end of the inlet pipe and the end of the outlet pipe, a second connecting plate provided on the top of the first connecting plate, and a pipe body connected to the second connecting plate, and two through holes opened on the second connecting plate, and circular holes 16 opened on both sides of the top of the first connecting plate, with a rotating block rotatably installed inside the circular hole, a rotating rod fixed to the top of the rotating block through the through hole, a limit plate installed at the top of the rotating rod, and two anti-slip pads installed on the outer wall of the rotating rod with glue.

[0007] By adopting the above technical solution, external cold water can enter the cooling water pipe through the inlet pipe, flow in the cooling water pipe and absorb heat, thereby cooling the inner shell. The water that has absorbed heat can be discharged through the outlet pipe.

[0008] Furthermore, the bottom of the limiting plate is provided with anti-slip texture, and the bottom of the limiting plate is in contact with the top of the second connecting plate.

[0009] By adopting the above technical solution, the bottom of the limiting plate is provided with anti-slip texture, thereby improving the anti-slip performance of the limiting plate and enhancing its stability.

[0010] Furthermore, a rotating column is fixed to the top of the limiting plate, and the outer wall of the rotating column is provided with anti-slip texture.

[0011] By adopting the above technical solution, it is convenient for staff to rotate the limiting plate through the rotating column in order to adjust the position of the limiting plate.

[0012] Furthermore, a sealing ring is provided on the top of the first connecting plate, the top of which fits against the bottom of the second connecting plate, and the sealing ring is made of silicone rubber.

[0013] By adopting the above technical solution, the sealing ring can improve the sealing performance between the first connecting plate and the second connecting plate, preventing cold water leakage.

[0014] Furthermore, end caps are installed at both ends of the inner shell, and sealed bearings are installed on the end caps, with a rotating shaft connecting the two sealed bearings.

[0015] By adopting the above technical solution, the end cap design facilitates sealing of both sides of the inner shell, thereby improving the sealing performance of the inner shell.

[0016] Furthermore, the outer wall of the rotating shaft is provided with a rotor, the inner wall of the inner shell is installed with a stator, and the rotor is located inside the stator.

[0017] By adopting the above technical solution, the sealed bearing facilitates shaft rotation.

[0018] Furthermore, a base is installed at the bottom of the outer casing, and the base has mounting holes.

[0019] By adopting the above technical solution, the design of the base and mounting holes facilitates the installation of the permanent magnet motor.

[0020] Furthermore, the outer wall of the anti-slip pad is tightly fitted to the inner wall of the opening, and the anti-slip pad is made of silicone rubber material.

[0021] By adopting the above technical solution, the anti-slip pad can improve the stability of the rotating rod.

[0022] Furthermore, the limiting plate is adapted to the opening, and guide rods penetrating the first connecting plate are installed on both sides of the bottom of the second connecting plate.

[0023] By adopting the above technical solution, when the limiting plate is aligned with the opening, the tube body moves upward, the second connecting plate moves upward, and the limiting plate can pass through the opening.

[0024] Furthermore, both the inner and outer shells are made of aluminum alloy.

[0025] By adopting the above technical solution, the inner shell is made of aluminum alloy material to facilitate heat conduction, so that the cold water in the cooling water pipe can cool the inner shell.

[0026] In summary, the present invention has the following main advantages: 1. This utility model, by setting up a through-hole, a rotating block, a rotating rod, a limiting plate, and a rotating column, allows for the connection of inlet and outlet pipes to an external pipe body. When connecting the inlet and outlet pipes to the external pipe body, the second connecting plate at the end of the external pipe body can be aligned with the first connecting plate, and the limiting plate aligned with the through-hole. Then, the second connecting plate is lowered so that the limiting plate passes through the through-hole. When the first and second connecting plates are closed, the bottom of the limiting plate is flush with the top of the second connecting plate. Next, the limiting plate is rotated 90° to offset it from the through-hole. The presence of an anti-slip pad, with its outer wall tightly fitted to the inner wall of the through-hole, improves the stability of the rotating rod and prevents it from rotating arbitrarily. The anti-slip texture on the bottom of the limiting plate further enhances its stability and prevents arbitrarily rotating. This completes the connection between the first and second connecting plates. Furthermore, this method results in a simple structure and facilitates maintenance. 2. This utility model has a round hole to facilitate the rotation of the rotating rod and prevent the rotating rod from moving out of the round hole. The sealing ring can improve the sealing between the first connecting plate and the second connecting plate and prevent water from leaking between the first connecting plate and the second connecting plate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1: High-efficiency water-cooled permanent magnet motors, such as Figures 1-7As shown, the device includes an inner shell 1, with end caps 4 installed at both ends of the inner shell 1. Sealed bearings 5 ​​are installed on the end caps 4, and a rotating shaft 6 is connected between the two sealed bearings 5. The end caps 4 facilitate sealing of both sides of the inner shell 1, improving the sealing performance of the inner shell 1. A rotor 8 is provided on the outer wall of the rotating shaft 6, and a stator 7 is installed on the inner wall of the inner shell 1. The rotor 8 is located inside the stator 7.

[0032] See Figures 1-5 The inner shell 1 has a cooling cavity 9 on its outer wall, and a cooling water pipe 10 is installed inside the cooling cavity 9. The outer shell 2 is installed on the outer wall of the inner shell 1. The inlet end of the cooling water pipe 10 is connected to an inlet pipe 11 extending to the outside of the outer shell 2, and the outlet end of the cooling water pipe 10 is connected to an outlet pipe 12 extending to the outside of the outer shell 2. A first connecting plate 13 is installed at the end of the inlet pipe 11 and the end of the outlet pipe 12. A second connecting plate 15 is provided on the top of the first connecting plate 13, and a pipe body 14 is connected to the second connecting plate 15. Two openings 17 are provided. The top of the first connecting plate 13 is provided with round holes 16 on both sides. A rotating block 18 is rotatably provided inside the round hole 16. A rotating rod 19 that passes through the opening 17 is fixed on the top of the rotating block 18. A limit plate 20 is installed on the top of the rotating rod 19. Two anti-slip pads 22 are installed on the outer wall of the rotating rod 19 with glue. External cold water can enter the cooling water pipe 10 through the water inlet pipe 11 and flow in the cooling water pipe 10 and absorb heat, thereby cooling the inner shell 1. The water that has absorbed heat can be discharged through the water outlet pipe 12.

[0033] Specifically, a rotating post 21 is fixed to the top of the limiting plate 20. The outer wall of the rotating post 21 is provided with anti-slip texture, which makes it convenient for the operator to rotate the limiting plate 20 through the rotating post 21 to adjust the position of the limiting plate 20. The outer wall of the anti-slip pad 22 is in close contact with the inner wall of the opening 17. The anti-slip pad 22 is made of silicone rubber material. The setting of the anti-slip pad 22 can improve the stability of the rotating rod 19. The limiting plate 20 is adapted to the opening 17. Guide rods 24 that penetrate the first connecting plate 13 are installed on both sides of the bottom of the second connecting plate 15. When the limiting plate 20 is aligned with the opening 17, the tube body 14 moves up, the second connecting plate 15 moves up, and the limiting plate 20 can pass through the opening 17.

[0034] Example 2: Based on the above embodiment 1, the following method will be adopted to improve the stability of the limiting plate 20.

[0035] See Figures 1-7The bottom of the limiting plate 20 is provided with anti-slip texture. The bottom of the limiting plate 20 is in contact with the top of the second connecting plate 15. The anti-slip texture on the bottom of the limiting plate 20 improves the anti-slip performance of the limiting plate 20 and enhances the stability of the limiting plate 20.

[0036] Example 3: Based on the above embodiment 1, in order to improve the sealing between the first connecting plate 13 and the second connecting plate 15 and prevent water leakage, the following structure will be set.

[0037] Specifically, the top of the first connecting plate 13 is provided with a sealing ring 23, the top of the sealing ring 23 is in contact with the bottom of the second connecting plate 15, the sealing ring 23 is made of silicone rubber material, the setting of the sealing ring 23 can improve the sealing between the first connecting plate 13 and the second connecting plate 15 and prevent cold water leakage.

[0038] Example 4: Based on the above embodiment 1, in order to facilitate the heat conduction of the inner shell 1, the following materials will be used to make the inner shell 1.

[0039] See Figures 1-2 Both the inner shell 1 and the outer shell 2 are made of aluminum alloy. The inner shell 1 is made of aluminum alloy to facilitate heat conduction, so that the cold water in the cooling water pipe 10 can cool the inner shell 1.

[0040] The working principle of this utility model is as follows: First, before use, the operator connects the inlet pipe 11 and outlet pipe 12 of the cooling water pipe 10 to the outer pipe body 14. During connection, the second connecting plate 15 at the end of the outer pipe body 14 can be aligned with the second connecting plate 15, and the limiting plate 20 can be aligned with the through-hole 17. Then, the second connecting plate 15 is moved down so that the limiting plate 20 passes through the through-hole 17. When the first connecting plate 13 and the second connecting plate 15 are closed, the bottom of the limiting plate 20 is flush with the top of the second connecting plate 15. Then, the limiting plate 20 is rotated ninety degrees so that the limiting plate 20 is misaligned with the through-hole 17, and the outer wall of the anti-slip pad 22 is tightly fitted with the inner wall of the through-hole 17, which can improve the stability of the rotating rod 19. In addition, the anti-slip texture on the bottom of the limiting plate 20 can improve the stability of the limiting plate 20 and prevent the limiting plate 20 from rotating at will. In this way, the connection of the first connecting plate 13 and the second connecting plate 15 can be completed. Both the inner shell 1 and the outer shell 2 of the motor are made of aluminum alloy. The good thermal conductivity of aluminum alloy is used to transfer the heat generated by the stator 7 and rotor 8 during the operation of the motor to the inner shell 1. When external cold water enters the cooling water pipe 10 through the water inlet pipe 11, it absorbs the heat of the inner shell 1 during the flow in the cooling chamber 9, thus achieving efficient heat dissipation of the inner shell 1. The hot water after absorbing heat is discharged through the water outlet pipe 12, completing the cooling cycle.
