Description

Technical Field

[0001] This application relates to the field of servo motor technology, specifically a liquid-cooled synchronous servo motor. Background Technology

[0002] As a key component in automation systems, the stable and efficient operation of servo motors is crucial to the overall system performance. To effectively reduce the temperature rise generated during motor operation and ensure its normal and stable operation, cooling devices are widely used in existing technologies. Among them, liquid-cooled servo motors are favored due to their advantages such as no noise and high cooling efficiency.

[0003] Existing liquid-cooled servo motors typically achieve cooling by mounting an integrated liquid cooling system on the motor housing. However, when the motor operates at high speeds, the temperature of the coolant gradually rises due to the continuous flow within the motor. Because the coolant struggles to dissipate heat effectively inside the motor, the cooling effect gradually diminishes, and the motor components face greater thermal stress due to the sustained high temperatures, thus shortening their lifespan.

[0004] Therefore, this application provides a liquid-cooled synchronous servo motor to solve the above problems. Utility Model Content

[0005] This application provides a liquid-cooled synchronous servo motor, aiming to solve the problems mentioned in the background art, such as the gradual increase in temperature of existing motors during high-speed operation due to the continuous flow of coolant inside the motor. Because the coolant cannot effectively dissipate heat inside the motor, the cooling effect gradually weakens, and the various components of the motor face greater thermal stress due to continuous high temperatures, thus shortening their service life.

[0006] To achieve the above objectives, this application provides the following technical solution: a liquid-cooled synchronous servo motor, including a motor body, one end of which is respectively provided with a liquid outlet and a liquid inlet, and the motor body is provided with a cooling structure for cooling the coolant inside the motor body.

[0007] The cooling structure includes a heat sink fixedly mounted at one end of the motor body and connected to the outlet and inlet; a heat absorption tube fixedly inserted into the heat sink and immersed in coolant; heat dissipation tubes fixedly connected to both ends of the heat absorption tube; and several fins fitted onto the heat dissipation tubes. During motor operation, coolant inside the motor enters the heat sink through the outlet. As the coolant flows within the heat sink, it comes into contact with the heat absorption tube, which absorbs heat from the coolant and transfers it to the heat dissipation tubes. The fins on the heat dissipation tubes increase the heat dissipation area, allowing heat to dissipate to the outside air more quickly. The cooled coolant then flows back into the motor body through the inlet to continue cooling the motor. This cycle repeats continuously, achieving continuous cooling of the coolant inside the motor.

[0008] Preferably, to improve the sealing performance between the heat sink and the motor body, the heat sink is provided with a sealing ring for sealing the gap between the heat sink and the motor body. The sealing ring improves the sealing effect between the heat sink and the motor body.

[0009] Preferably, heat dissipation grooves are provided on both sides of the heat dissipation box, and the fins are disposed within the heat dissipation grooves. By installing the fins within the heat dissipation grooves, the fins can be protected, preventing deformation caused by impacts.

[0010] Preferably, to improve the heat dissipation effect of the fins: the heat sink has an internal air chamber communicating with the heat dissipation slots, and a fan blade is rotatably mounted inside the air chamber. The fan blade is fixedly mounted on the shaft of the motor body. Through the synchronous rotation of the fan blade, a strong airflow is generated inside the air chamber. The airflow directly blows across the fins and heat pipes, greatly enhancing the heat dissipation effect, allowing the coolant temperature to drop faster, and making the motor operation more stable.

[0011] Preferably, to facilitate the circulation of coolant inside the heat sink and the motor, an impeller is rotatably mounted inside the heat sink, and the impeller is fixedly mounted on the shaft of the motor body. By adding the impeller and utilizing the rotational power of the motor shaft, efficient circulation of coolant is achieved, thus improving heat dissipation efficiency.

[0012] This application utilizes the combination of heat-absorbing pipes, heat-dissipating pipes, and fins in its cooling structure to rapidly absorb heat from the coolant and dissipate it into the outside air, ensuring that the coolant maintains a low temperature throughout its circulation. Because the coolant temperature is effectively controlled, the motor's internal components will not be damaged by high temperatures, thus improving the motor's stability and lifespan. The cooling structure has a simple and clear design, with robust and reliable connections between components, facilitating routine maintenance and repair.

[0013] This application utilizes the synchronous rotation of the fan blades to generate a powerful airflow within the air chamber. This airflow directly sweeps across the fins and heat pipes, significantly enhancing heat dissipation and allowing the coolant temperature to drop more quickly, resulting in more stable motor operation. The fan blades operate using the rotational power of the motor shaft, requiring no additional energy consumption, thus aligning with the principles of energy conservation and emission reduction.

[0014] This application achieves efficient circulation of coolant by adding an impeller and utilizing the rotational power of the motor shaft, thus improving heat dissipation efficiency. Combined with the cooling structure, the coolant can continuously absorb and dissipate heat from inside the motor during circulation, ensuring that the motor maintains good heat dissipation performance even under high-intensity operating conditions.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a liquid-cooled synchronous servo motor, such as Figure 1-4 As shown, the servo motor includes a motor body 1, one end of which is provided with a liquid outlet 11 and a liquid inlet 12, and the motor body 1 is provided with a cooling structure 2 for cooling the coolant inside the motor body 1.

[0024] The cooling structure 2 includes a heat sink 21 fixedly mounted at one end of the motor body 1 and connected to the outlet 11 and inlet 12; a heat absorption pipe 22 fixedly inserted into the heat sink 21 and immersed in the coolant; heat dissipation pipes 23 fixedly connected to both ends of the heat absorption pipe 22; and several fins 24 fitted onto the heat dissipation pipes 23. Through the cooperation of the heat absorption pipe 22, heat dissipation pipes 23, and fins 24 in the cooling structure 2, heat inside the coolant can be quickly absorbed and dissipated into the outside air, ensuring that the coolant maintains a low temperature throughout its circulation. Because the coolant temperature is effectively controlled, the internal components of the motor will not be damaged by high temperatures, thereby improving the motor's stability and service life. The design of the cooling structure 2 is simple and clear, with robust and reliable connections between components, facilitating daily maintenance and repair. During motor operation, the coolant inside the motor enters the interior of the heat sink 21 through the outlet 11. As the coolant flows within the radiator 21, it comes into contact with the heat absorption pipe 22, which absorbs the heat from the coolant and transfers it to the heat dissipation pipe 23. The fins 24 on the heat dissipation pipe 23 increase the heat dissipation area, allowing heat to dissipate into the outside air more quickly. After cooling, the coolant flows back into the motor body 1 through the inlet 12 to continue cooling the motor. This cycle repeats continuously, achieving continuous cooling of the coolant inside the motor.

[0025] To improve the sealing performance between the heat sink 21 and the motor body 1, a sealing ring 211 is provided on the heat sink 21 to seal the gap between the heat sink 21 and the motor body 1. The sealing ring 211 can improve the sealing effect between the heat sink 21 and the motor body 1.

[0026] The heat sink 21 has heat dissipation slots 212 on both sides, and the fins 24 are installed in the heat dissipation slots 212. By installing the fins 24 in the heat dissipation slots 212, the fins 24 can be protected and prevent the fins 24 from being deformed due to impact.

[0027] Example 2

[0028] Unlike Embodiment 1, to improve the heat dissipation effect of the fins 24, an air chamber 213 communicating with the heat dissipation slots 212 is provided inside the heat sink 21. A fan blade 3 is rotatably mounted inside the air chamber 213 and is fixedly mounted on the shaft of the motor body 1. Through the synchronous rotation of the fan blade 3, a strong airflow is generated inside the air chamber 213. This airflow directly blows across the fins 24 and the heat dissipation pipes 23, greatly enhancing the heat dissipation effect, allowing the coolant temperature to drop faster, and making the motor operation more stable. The fan blade 3 operates using the rotational power of the motor shaft, requiring no additional energy consumption, which aligns with the concept of energy conservation and emission reduction. During motor operation, coolant enters the heat sink 21 through the outlet 11, contacts the heat absorption pipe 22, and absorbs heat. Subsequently, the coolant transfers heat to the fins 24 through the heat dissipation pipes 23. Simultaneously, the motor shaft drives the fan blade 3 to rotate synchronously, generating airflow inside the air chamber 213. Airflow enters the heat sink 212 through a specific channel in the air chamber 213, directly blowing on the fins 24 and heat pipes 23, carrying away the heat from the fins 24 and dissipating it into the outside air. The cooled coolant then flows back into the motor body 1 through the inlet 12 to continue cooling the motor. This cycle repeats continuously, achieving continuous and efficient cooling of the coolant inside the motor.

[0029] Example 3

[0030] Unlike Embodiment 1, to facilitate the circulation of coolant inside the heat sink 21 and the motor, an impeller 4 is rotatably mounted inside the heat sink 21, and the impeller 4 is fixedly mounted on the shaft of the motor body 1. By adding the impeller 4 and utilizing the rotational power of the motor shaft, efficient circulation of coolant is achieved, improving heat dissipation efficiency. Combined with the cooling structure 2, the coolant can continuously absorb and dissipate heat from inside the motor during circulation, ensuring that the motor maintains good heat dissipation performance even under high-intensity working conditions. During motor operation, the motor shaft drives the impeller 4 to rotate synchronously. The rotation of the impeller 4 generates a pumping effect, pumping the coolant from inside the motor into the heat sink 21 through the outlet 11. Inside the heat sink 21, the coolant contacts the heat absorption pipe 22 and absorbs heat, which is then transferred to the fins 24 through the heat dissipation pipe 23. At the same time, the fan blades 3 generate airflow inside the air chamber 213, sweeping the fins 24 and carrying away heat. The cooled coolant then flows back into the motor through inlet 12, where it exchanges heat with the internal components and is heated again. This cycle repeats continuously, creating a continuous and efficient circulation and heat dissipation process between the coolant inside the motor and the heat sink 21.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
