Description

Technical Field

[0001] This utility model relates to the field of micro motor technology, specifically a motor based on heat dissipation materials. Background Technology

[0002] With the continuous trend towards miniaturization and high performance in modern industry and electronic devices, the performance and reliability of micro motors, as core power components in many devices, are becoming increasingly critical. Micro motors are widely used in fields such as smartphones, drones, medical devices, and industrial automation equipment. In these applications, not only are high-efficiency power output required for micro motors, but also extremely high demands are placed on their heat dissipation performance.

[0003] Traditional heat dissipation methods for micro motors have many limitations. Traditional micro motors primarily rely on natural heat dissipation, that is, dissipating internal heat through natural convection and thermal radiation between the motor casing and the surrounding air. However, as the power of micro motors continues to increase and their size continues to decrease, the efficiency of natural heat dissipation becomes insufficient, failing to dissipate heat effectively and promptly. This leads to a rapid rise in the internal temperature of the motor, and excessively high temperatures can have serious negative impacts on motor performance, such as increasing the resistance of the stator windings, thereby increasing power loss, reducing motor efficiency, and shortening the motor's lifespan. Furthermore, traditional motor casing materials such as aluminum alloys and plastics also have their shortcomings. Although aluminum alloys have some thermal conductivity, their heat dissipation capacity is still insufficient for high-power operation in miniaturized micro motors. Plastic materials have extremely poor thermal conductivity, primarily serving a protective and insulating function, contributing negligibly to heat dissipation. Utility Model Content

[0014] This invention provides a motor based on heat dissipation materials. By setting heat dissipation channels on the outer shell and connecting them with coolant circulation components and heat exchange components, an active heat dissipation system is constructed. The coolant circulation components can carry away heat from the heat dissipation channels, while the heat exchange components dissipate the heat carried by the coolant to the outside, significantly improving the heat dissipation efficiency of the micro motor, helping to reduce the motor's operating temperature, ensuring its stable operation, and extending its service life.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example

[0023] Please refer to Figures 1 to 3 As shown, this embodiment provides a motor based on heat dissipation material, including: a stator, a rotor, and a housing 1. The stator and rotor are disposed inside the housing 1. The housing 1 is provided with a heat dissipation channel 2, which is connected to a coolant circulation component. The coolant circulation component is equipped with a heat exchange component. By providing a heat dissipation channel 2 on the housing 1 and connecting the coolant circulation component and the heat exchange component, an active heat dissipation system is constructed. The coolant circulation component can carry away heat from the heat dissipation channel, while the heat exchange component dissipates the heat carried by the coolant to the outside, significantly improving the heat dissipation efficiency of the micro motor, helping to reduce the motor's operating temperature, ensuring its stable operation, and extending its service life.

[0024] The heat dissipation channel 2 is spirally arranged inside the outer shell 1. This spiral arrangement increases the contact area and contact time between the coolant and the outer shell 1. When the coolant flows in the spiral channel, it can more fully absorb the heat transferred from the outer shell 1, thus enhancing the heat dissipation effect. In addition, the spiral channel allows the coolant to achieve a longer flow path in a limited space, further improving the heat dissipation efficiency and ensuring that all parts of the micro motor are effectively cooled.

[0025] The coolant circulation component includes a mounting plate 3 fixedly installed at the bottom of the outer casing 1. A coolant tank 4 is fixedly installed on the top of the mounting plate 3. One side of the coolant tank 4 is connected to the inlet end of the heat dissipation channel 2 through a first delivery pipe 5, and the other side of the coolant tank 4 is connected to the outlet end of the heat dissipation channel 2 through a second delivery pipe 7. A delivery pump 6 is fixedly installed on the first delivery pipe 5 and fixed to the bottom of the outer casing 1 by the mounting plate 3, providing a stable mounting base for components such as the coolant tank 4 and the delivery pump 6. The coolant tank 4 stores coolant. The first delivery pipe 5 and the second delivery pipe 7 are respectively connected to the inlet and outlet of the heat dissipation channel 2. The delivery pump 6 can drive the coolant to flow in the circulation system, ensuring the stability and reliability of the coolant circulation and providing a strong guarantee for efficient heat dissipation.

[0026] The heat exchange components include a cooling fan 8 fixedly mounted on the mounting plate 3 and a heat dissipation fin 701 integrally formed on the second delivery pipe 7. The cooling fan 8 is located directly below the heat dissipation fin 701, and the output surface of the cooling fan 8 faces the heat dissipation fin 701. Through the coordinated work of the cooling fan 8 and the heat dissipation fin 701, the airflow blown by the cooling fan 8 can quickly remove the heat on the heat dissipation fin 701, thereby accelerating the heat dissipation of the coolant in the second delivery pipe 7. The cooling fan 8 being located directly below the heat dissipation fin 701 and having its output surface facing the heat dissipation fin 701 ensures that the airflow can effectively act on the heat dissipation fin 701, enhancing the convective heat transfer effect, effectively improving the heat dissipation speed of the coolant, and further improving the overall heat dissipation performance of the micro motor.

[0027] The controller 9 is fixedly installed on the mounting plate 3, and the temperature sensor 10 is fixedly installed on the inner wall of the housing 1. The controller 9 is electrically connected to the delivery pump 6, the cooling fan 8, and the temperature sensor 10. Through the electrical connection between the controller 9, the temperature sensor 10, the delivery pump 6, and the cooling fan 8, an intelligent heat dissipation control system is constructed. The temperature sensor 10 monitors the temperature inside the housing 1 in real time and feeds the data back to the controller 9. When the temperature exceeds the set threshold, the controller 9 automatically starts the delivery pump 6 and the cooling fan 8 to accelerate the circulation of coolant and the heat dissipation speed. When the temperature drops to a suitable range, the controller 9 can adjust the working intensity of the delivery pump 6 and the cooling fan 8 or stop them from working. It can flexibly adjust the operating status of the heat dissipation system according to the actual working temperature of the micro motor, which not only ensures the heat dissipation effect but also saves energy and improves the intelligence level and reliability of the system.

[0028] The outer shell 1 is made of ceramic composite material, and several heat dissipation grooves 101 are provided around the outer wall of the outer shell 1. The use of ceramic composite material in the outer shell 1 provides high hardness, good electrical insulation and high thermal stability. At the same time, the heat dissipation grooves 101 on the outer wall further increase the heat dissipation area of ​​the outer shell 1, which helps heat to be dissipated into the surrounding environment more quickly. The combination of ceramic composite material and heat dissipation grooves 101 significantly improves heat dissipation capacity while ensuring the mechanical and electrical performance of the outer shell 1, providing good external conditions for the stable operation of the micro motor.

[0029] The inner wall of the outer casing 1 is coated with a thermally conductive coating 102, which is thermally conductive silicone. By applying thermally conductive silicone to the inner wall of the outer casing 1, the thermal resistance between the outer casing 1 and internal heat-generating components such as the stator and rotor can be effectively reduced. The thermally conductive silicone has good thermal conductivity and flexibility, and can fit tightly against the inner wall of the outer casing 1, so as to quickly transfer the heat generated inside to the outer casing 1, and then dissipate it through the heat dissipation channel and the outer wall of the outer casing 1, further optimizing the heat transfer path inside the micro motor and improving the heat dissipation efficiency.

[0030] Among them, the first conveying pipe 5, the second conveying pipe 7, and the heat dissipation fins 701 are all made of copper. During the circulation and heat dissipation of the coolant, the copper pipes can quickly transfer the heat carried by the coolant to the heat dissipation fins 701, and the heat dissipation fins 701 can then efficiently dissipate the heat into the air. This can effectively reduce the heat loss during the transmission process, improve the thermal conductivity of the heat dissipation system, and thus enhance the heat dissipation performance of the micro motor.

[0031] It is worth noting that the controller 9 can be an STM32F103, and the temperature sensor 10 can be a DS18B20.

[0032] As is well known to those skilled in the art, the working principles and wiring methods of the delivery pump 6, cooling fan 8, controller 9, and temperature sensor 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can select any model according to their needs or convenience.

[0033] Working principle: During use, the temperature sensor 10 monitors the temperature change inside the outer casing 1 in real time and transmits the temperature data to the controller 9. When the temperature rises to a preset threshold, the controller 9 issues a command to start the delivery pump 6, which pumps the coolant in the coolant tank 4 into the heat dissipation channel 2 through the first delivery pipe 5. Since the heat dissipation channel 2 is spirally arranged inside the outer casing 1, the coolant fully absorbs the heat transferred from the outer casing 1 during the flow, and the temperature gradually rises. The coolant, after absorbing heat, flows out from the outlet end of the heat dissipation channel 2 and returns to the coolant tank 4 through the second delivery pipe 7, completing one cycle. During the coolant return process through the second delivery pipe 7, the cooling fan 8 mounted on the mounting plate 3 starts, with its output surface facing the heat dissipation fins 701. The heat dissipation fins 701 are integrally formed on the second delivery pipe 7. Since the first delivery pipe 5, the second delivery pipe 7, and the heat dissipation fins 701 are all made of copper, they have excellent thermal conductivity. The heat of the coolant is quickly transferred to the heat dissipation fins 701. The airflow blown out by the cooling fan 8 accelerates the heat exchange between the heat dissipation fins 701 and the surrounding air, dissipating the heat into the surrounding environment and lowering the coolant temperature, thereby achieving heat dissipation of the coolant and preparing for the next cycle.

[0034] The high thermal conductivity ceramic composite material, composed of an aluminum nitride ceramic matrix and silicon carbide whiskers, has excellent thermal conductivity. The aluminum nitride ceramic itself has high thermal conductivity, and the silicon carbide whiskers are uniformly dispersed in it, further forming an efficient heat conduction network. When the micro motor generates heat during operation, the heat can be quickly conducted to the surface of the outer shell 1 through the composite material. Compared with traditional metal or plastic outer shell materials, the heat transfer speed is faster, which can dissipate the heat inside the motor in a short time, significantly reduce the temperature gradient inside the motor, prevent local overheating, and maintain the stable operation of each component.
