Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, and more specifically, it relates to a motor with heat dissipation function. Background Technology
[0002] In the field of electric motors, excellent heat dissipation is often required. During prolonged operation, to ensure normal operation and extend the motor's lifespan, it's essential to effectively dissipate the generated heat. However, traditional motors typically rely solely on fan blades for heat dissipation. When operating under high loads for extended periods, the fan blades alone are insufficient to quickly dissipate heat, leading to a continuous rise in the motor's internal temperature. Excessive internal temperature degrades the motor's insulation performance, increasing the risk of short circuits and other malfunctions. Frequent motor failures not only disrupt the normal operation of the driven equipment, causing production stoppages, but also increase operating costs due to repeated repairs or replacements, ultimately reducing the company's market competitiveness. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a motor with heat dissipation function, which solves the technical problem that in the prior art, traditional motors usually rely solely on the rotation of fan blades for heat dissipation, and the fan blades alone cannot quickly dissipate the heat.
[0004] The purpose and effect of this utility model of a motor with heat dissipation function are achieved by the following specific technical means:
[0005] A motor with heat dissipation function includes a housing, an inner mounting ring, and multiple sets of fixing blocks arranged in a ring at equal intervals. A stator core is positioned between every two sets of fixing blocks, and a stator winding is wound around the stator core. A cooling assembly is disposed within each fixing block. A rotor core is inserted into the mounting ring, and multiple sets of permanent magnets and a rotating shaft are clamped within the rotor core. Both ends of the rotor core are provided with cover plates. One end of the housing is provided with an end cap, and the other end is provided with a heat dissipation assembly. A mounting base for external connection is installed at the bottom of the housing.
[0006] According to a preferred embodiment, the cooling assembly includes multiple sets of cooling pipes, a cooling groove is provided in the fixing block, the cooling pipes pass through the cooling groove, and the multiple sets of cooling pipes are connected end to end to form a serpentine cooling pipe, with both ends extending out of the outer shell.
[0007] According to a preferred embodiment, the cooling pipe is filled with coolant, and the cooling assembly is connected to an external circulating water pump; both the cooling pipe and the mounting ring are made of pure copper.
[0008] According to a preferred embodiment, the heat dissipation assembly includes a base plate and heat dissipation fan blades. The base plate is installed at one end of the housing, and the heat dissipation fan blades are sleeved on one end of the rotating shaft, with the heat dissipation fan blades located inside the base plate.
[0009] According to a preferred embodiment, the heat dissipation assembly further includes a partition plate, which is sleeved on the rotating shaft and installed on one side of the base plate. Heat dissipation grooves are formed on both the partition plate and the periphery of the base plate.
[0010] According to a preferred embodiment, one end of the rotating shaft extends through the end cover, and bearings are installed in both the end cover and the partition plate, with the rotating shaft passing through the bearing; multiple sets of guide grooves are formed on the periphery of the rotor core.
[0011] According to a preferred embodiment, the outer casing is provided with multiple sets of heat dissipation fins; the space between the stator core and the two sets of fixing blocks is filled with thermal grease.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention utilizes a cooling assembly with cooling pipes inserted into the cooling grooves of a fixed block. Multiple sets of cooling pipes are connected end-to-end to form a serpentine cooling pipeline, with both ends extending out of the outer casing. This allows the user to utilize the circulating coolant to remove internal heat from the motor, improving its heat dissipation capacity and effectively reducing the motor's internal temperature. This ensures stable motor operation and enhances the motor's ability to withstand the heat generated during prolonged operation. Furthermore, the cooling pipes and mounting rings are made of pure copper, further enhancing heat conduction efficiency.
[0014] When using this motor, users can accelerate airflow and remove heat by using the cooling fan blades in the heat dissipation assembly, which are fitted inside the base plate at one end of the shaft. This further enhances the heat dissipation effect and improves the motor's cooling efficiency. Furthermore, the shaft is mounted smoothly within the end cover and partition via bearings. The guide grooves around the rotor core, the cooling fins around the outer casing, and the thermal grease between the stator core and the fixing block work together to comprehensively improve the motor's heat dissipation capacity and operational stability.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example:
[0022] like Figures 1 to 4 As shown, this utility model provides a motor with heat dissipation function, including a housing 11, a mounting ring 12 passing through the housing 11, and multiple sets of slots formed within the housing 11. Fixing strips are provided around the mounting ring 12, and these fixing strips are engaged within the slots, providing a mounting position for the mounting ring 12 and preventing rotation. The mounting ring 12 plays a crucial role in supporting internal components. Multiple sets of fixing blocks 13 are arranged within the mounting ring 12 in a ring-shaped, equidistant manner, providing support for the stator core 14. The stator core 14 is placed between every two sets of fixing blocks 13, and stator windings 15 are tightly wound around the outside of the stator core 14. When energized, the stator windings 15 generate a magnetic field, thereby driving the motor. A cooling assembly is installed inside the fixing blocks 13, which effectively reduces the heat generated during motor operation, ensuring stable motor operation.
[0023] Inside the mounting ring 12, a rotor core 16 is also installed. Multiple sets of permanent magnets 17 and a rotating shaft 18 are fitted inside the rotor core 16. The magnetic field generated by the permanent magnets 17 and the stator windings 15 interacts, allowing the rotating shaft 18 to rotate. Both ends of the rotor core 16 are equipped with cover plates 19, which protect and secure the internal components such as the permanent magnets 17. An end cover 21 is installed at one end of the outer casing 11, and a heat dissipation assembly is installed at the other end. Simultaneously, a mounting base 22 is installed at the bottom of the outer casing 11, through which the motor can be connected to external equipment.
[0024] like Figures 2 to 4As shown, the cooling assembly includes multiple sets of cooling pipes 23. A cooling groove 24 is pre-formed within the fixing block 13, and the cooling pipes 23 pass through the cooling groove 24. The multiple sets of cooling pipes 23 are connected end-to-end via pipes, ultimately forming a serpentine cooling pipe. Both ends of this serpentine cooling pipe extend out of the outer casing 11. This design allows the cooling pipes 23 to better absorb the heat generated by the stator winding 15 and transfer the heat away.
[0025] Cooling pipe 23 contains coolant, and the cooling assembly is connected to an external circulating water pump. Through the external circulating water pump, the coolant circulates within cooling pipe 23, continuously carrying away heat, while simultaneously flowing through an external cooling device to cool the coolant. Both cooling pipe 23 and mounting ring 12 are made of pure copper. Pure copper has excellent thermal conductivity, enabling it to quickly transfer heat to the coolant and improve heat dissipation efficiency.
[0026] like Figures 2 to 3 As shown, the heat dissipation assembly includes a base plate 25 and a cooling fan blade 26. The base plate 25 is mounted on one end of the housing 11, and the cooling fan blade 26 is sleeved on one end of the rotating shaft 18, with the cooling fan blade 26 located inside the base plate 25. When the motor is running, the rotating shaft 18 drives the cooling fan blade 26 to rotate, generating airflow, thereby accelerating the dissipation of heat inside the motor.
[0027] The heat dissipation assembly also includes a partition 27, which is sleeved on the rotating shaft 18 and fixed to one side of the base plate 25. Heat dissipation slots are formed on the partition 27 and the periphery of the base plate 25. These slots connect the inside of the motor to the outside, allowing the hot air generated during motor operation to be smoothly discharged to the outside, thus enhancing the heat dissipation effect.
[0028] One end of the rotating shaft 18 extends through the end cover 21. Bearings are installed in both the end cover 21 and the partition plate 27, and the rotating shaft 18 passes through these bearings, allowing the rotating shaft 18 to rotate smoothly. At the same time, multiple sets of guide grooves are formed on the periphery of the rotor core 16. When the rotor core 16 rotates, the guide grooves help the air flow inside the motor, further enhancing the heat dissipation effect.
[0029] Multiple sets of heat dissipation fins are provided around the periphery of the outer casing 11. The heat dissipation fins increase the contact area between the outer casing 11 and the air, which helps to dissipate the heat inside the motor into the surrounding air. Thermal grease is filled between the stator core 14 and the two sets of fixing blocks 13. The thermal grease can fill the tiny gaps and enhance the heat transfer efficiency between the stator core 14 and the fixing blocks 13, so that heat can be transferred to the cooling components more quickly.
[0030] The specific usage and function of this embodiment are as follows:
[0031] When the motor is running, the stator winding 15 is energized, generating a magnetic field that interacts with the permanent magnet 17 inside the rotor core 16, causing the shaft 18 to rotate. During motor operation, the stator winding 15 generates heat. Simultaneously, the cooling system begins to function. An external circulating water pump drives the coolant to circulate within a serpentine system of cooling pipes 23. The cooling pipes 23, made of pure copper, have excellent thermal conductivity, quickly absorbing heat from the stationary block 13 and its surroundings, which is then carried away by the coolant.
[0032] The rotating shaft 18 drives the cooling fan blades 26 to rotate, and the resulting airflow passes through the heat dissipation slots on the partition plate 27 and the base plate 25, accelerating the dissipation of heat inside the motor. The guide slots around the rotor core 16 assist the airflow inside the motor, enhancing the heat dissipation effect.
[0033] Furthermore, the heat dissipation fins around the outer casing 11 increase the contact area with the air, dissipating heat conducted from inside the motor to the casing 11. The thermal grease between the stator core 14 and the fixing block 13 effectively improves the heat transfer efficiency between them, allowing heat to be transferred to the cooling components more quickly. Through the coordinated work of these components, the motor can effectively dissipate heat during operation, ensuring stable motor operation and extending its service life.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
