A motor heat dissipation structure

Abstract

This utility model discloses a motor heat dissipation structure, including: a housing; and a rear cover. The beneficial effects of this utility model are: it adopts a heat dissipation method combining air cooling and water cooling, which greatly improves the heat dissipation efficiency. For air cooling, the heat dissipation blades rotatably mounted on one side of the housing are connected to the motor stator and rotor assembly. When the motor is running, the heat dissipation blades rotate, accelerating the airflow in the housing and quickly removing heat. For water cooling, cooling water enters the system through the inlet tank. Part of it enters the spiral cooling water pipe, and the other part enters the side water ring through the inlet pipe. Then, it is evenly distributed around the outer temperature conducting sleeve through the distribution box and the water flow channel. The outer temperature conducting sleeve wraps around the motor stator and rotor assembly, which can quickly absorb the heat of the motor. After absorbing heat during the flow, the cooling water is collected in the outlet tank and discharged from the outlet pipe. This synergistic effect of air cooling and water cooling can dissipate the heat generated by the generator in a timely and effective manner, ensuring that the motor operates stably at a suitable temperature.

Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, specifically a heat dissipation structure for an electric motor. Background Technology

[0002] As a widely used power device in modern industry and daily life, the operating efficiency and stability of electric motors are crucial to the normal operation of various mechanical systems. During the operation of an electric motor, Joule heat is generated when current passes through the stator and rotor components, and eddy current losses and hysteresis losses are also caused by the alternation of the magnetic field inside the motor. These factors all lead to a large amount of heat being generated in the motor. If this heat cannot be dissipated in a timely and effective manner, the internal temperature of the motor will continue to rise. Traditional air-cooling methods usually involve setting heat sinks on the motor housing and relying on the natural convection of the surrounding air driven by the motor's operation, or installing additional fans to accelerate airflow to remove the heat generated by the motor. However, this air-cooling method is often not ideal in some situations with high heat dissipation requirements, especially when the motor is running under high load for a long time. Relying solely on natural air convection or simple forced convection by a fan is insufficient to quickly and effectively dissipate the large amount of heat generated inside the motor, causing the internal temperature of the motor to continue to rise. Utility Model Content

[0003] The purpose of this utility model is to provide a motor heat dissipation structure to solve the problem that the air cooling method mentioned in the background art is often not ideal in some situations with high heat dissipation requirements. Especially when the motor is running under high load for a long time, it is difficult to quickly and effectively dissipate the large amount of heat generated inside the motor by relying solely on natural air convection or simple fan forced convection, resulting in the motor's internal temperature continuing to rise.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a motor heat dissipation structure, comprising:

[0005] chassis;

[0006] The rear cover is installed on one side of the housing, and an outer temperature-conducting sleeve is provided on the inner side of the housing.

[0007] The motor stator and rotor assembly is disposed inside the outer temperature-conducting sleeve and inside the housing.

[0008] Side-flow water rings are arranged on both sides of the outer temperature-conducting sleeve. Four distribution boxes are arranged between each of the two side-flow water rings and the outer temperature-conducting sleeve. The distribution boxes are connected to the water flow channels and the distribution boxes are connected to the side-flow water rings through water pipes.

[0009] The spiral cooling water pipe is installed inside the casing. Three fixing rings are equidistantly arranged on the inner side of the spiral cooling water pipe, and multiple external fixing blocks are equidistantly fixed to the outer side of the fixing rings. The external fixing blocks are fixed to the casing by bolts.

[0010] As a preferred embodiment of this utility model: a heat dissipation blade is rotatably provided on one side of the housing, and the heat dissipation blade is connected to the motor stator and rotor assembly.

[0011] As a preferred embodiment of this utility model: one side of one of the side-flowing water rings is fixedly connected to an inlet pipe, and the other side of the side-flowing water ring is fixedly connected to an outlet pipe. One end of the spiral cooling water pipe and one end of the inlet pipe are both fixedly connected to an inlet tank, and the other end of the spiral cooling water pipe and one end of the outlet pipe are both fixedly connected to an outlet tank.

[0012] As a preferred embodiment of this utility model: a connecting pipe is fixedly connected to one side of both the inlet tank and the outlet tank, and an electrically controlled valve is installed on the connecting pipe.

[0013] As a preferred embodiment of this utility model, the fixing ring has multiple through holes inside.

[0014] As a preferred embodiment of this utility model: multiple heat dissipation fins are fixedly connected at equal intervals on the outer side of the housing, a connecting cover is fixedly installed on the side of the housing away from the rear cover by bolts, and a ventilation mesh is provided inside the rear cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a heat dissipation method combining air cooling and water cooling, which greatly improves the heat dissipation efficiency. For air cooling, the heat dissipation blades, which are rotatably mounted on one side of the casing, are connected to the motor stator and rotor assembly. When the motor runs, the heat dissipation blades rotate, accelerating the airflow through the casing and quickly removing heat. For water cooling, cooling water enters the system through the inlet tank. Part of it enters the spiral cooling water pipe, and the other part enters the side water ring through the inlet pipe. Then, it is evenly distributed around the outer thermal insulation jacket through the distribution box and water flow channel. The outer thermal insulation jacket wraps around the motor stator and rotor assembly, enabling it to quickly absorb heat from the motor. After absorbing heat during the flow process, the cooling water is collected in the outlet tank. The heat generated by the generator is collected in the water and discharged through the outlet pipe. This combination of air cooling and water cooling can effectively dissipate the heat generated by the generator in a timely manner, ensuring that the motor operates stably at a suitable temperature. The fixed rings that are equidistantly fixed to the inner side of the spiral cooling water pipe have multiple through holes inside, which reduces the weight of the fixed rings. The through holes increase the contact area between the fixed rings and the surrounding air, promote heat exchange, and further enhance the water cooling effect. The multiple heat dissipation fins that are equidistantly fixed to the outer side of the casing increase the heat dissipation area of ​​the casing, allowing the heat generated by the motor to be dissipated to the surrounding environment more quickly. The equidistant distribution of the heat dissipation fins makes the heat dissipation more uniform, avoids local overheating, and improves the overall heat dissipation performance of the motor.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a motor heat dissipation structure, including: a housing 1; a rear cover 3 fixedly installed on one side of the housing 1 by bolts, and an outer temperature conducting sleeve 5 provided on the inner side of the housing 1; a motor stator and rotor assembly 6 disposed on the inner side of the outer temperature conducting sleeve 5, and the motor stator and rotor assembly 6 disposed inside the housing 1; side water rings 10 disposed on both sides of the outer temperature conducting sleeve 5, and four diversion boxes 20 fixedly connected between each of the two side water rings 10 and the outer temperature conducting sleeve 5, the diversion boxes 20 being connected to the water flow channel 11, and the diversion boxes 20 being connected to the side water rings 10 by water pipes; a spiral cooling water pipe 19 disposed inside the housing 1, and three fixing rings 16 being fixedly connected at equal intervals on the inner side of the spiral cooling water pipe 19, and multiple outer fixing blocks 18 being fixedly connected at equal intervals on the outer side of the fixing rings 16, the outer fixing blocks 18 being fixed to the housing 1 by bolts.

[0024] It should be noted that in this embodiment, a heat dissipation blade 7 is rotatably arranged on one side of the casing 1, and the heat dissipation blade 7 is connected to the motor stator and rotor assembly 6. When the motor starts and the motor stator and rotor assembly 6 starts to operate, its rotational motion will drive the heat dissipation blade 7 to rotate together. A ventilation net 21 is provided inside the rear cover 3. During the airflow process driven by the heat dissipation blade 7, the ventilation net 21 ensures that the air can smoothly enter and exit the casing 1, making the air circulation smoother and further enhancing the air cooling effect. One side of the side water ring 10 is fixedly connected to a water inlet pipe 8, and the other side of the side water ring 10 is fixedly connected to a water outlet pipe 9. One end of the spiral cooling water pipe 19 and one end of the water inlet pipe 8 are both A water inlet tank 12 is fixedly connected to the spiral cooling water pipe 19, and a water outlet tank 13 is fixedly connected to one end of the outlet pipe 9, thus constructing a complete cooling water circulation path. Cooling water first enters the system through the water inlet tank 12. Part of the cooling water directly enters the spiral cooling water pipe 19, and the other part enters the side water ring 10 through the water inlet pipe 8. A distribution box 20 is fixedly connected between the side water ring 10 and the outer thermal insulation sleeve 5, and the distribution box 20 is connected to the water flow channel 11. At the same time, the distribution box 20 and the side water ring 10 are connected by water pipes. The cooling water entering the side water ring 10 will be distributed evenly around the outer thermal insulation sleeve 5 through the distribution box 20 and the water flow channel 11. 19 is located inside the housing 1. Its spiral structure increases the contact area with the surrounding air and internal components of the motor. The outer heat-conducting sleeve 5 wraps around the motor stator and rotor assembly 6, enabling it to quickly absorb the heat generated by the motor. When the cooling water flows in the channels around the spiral cooling water pipe 19 and the outer heat-conducting sleeve 5, it absorbs the heat transferred from the motor to the outer heat-conducting sleeve 5 and the surrounding air, causing the cooling water temperature to rise. The cooling water that has absorbed heat is collected centrally through the outlet tank 13 and then discharged from the system through the outlet pipe 9 for recycling. A connecting pipe 14 is fixedly connected to one side of both the inlet tank 12 and the outlet tank 13. An electrically controlled valve 15 is installed on the connecting pipe 14. By controlling the opening and closing of the electrically controlled valve 15, The flow rate and velocity of the cooling water can be adjusted. Three fixing rings 16 are fixedly connected at equal intervals on the inner side of the spiral cooling water pipe 19, and multiple external fixing blocks 18 are fixedly connected at equal intervals on the outer side of the fixing rings 16. The external fixing blocks 18 are fixed to the housing 1 by bolts, which ensures the stable installation of the spiral cooling water pipe 19 in the housing 1. Multiple through holes 17 are opened inside the fixing rings 16, which reduces the weight of the fixing rings 16 and the overall weight of the motor, which is beneficial to the installation and operation of the motor. The through holes 17 increase the contact area between the cooling water and the air around the fixing rings 16. Multiple heat dissipation fins 2 are fixedly connected at equal intervals on the outer side of the housing 1, which increases the heat dissipation area of ​​the housing 1 and together ensures the heat dissipation effect of the motor.

[0025] In one embodiment, such as Figures 1 to 5As shown, a heat dissipation blade 7 is rotatably mounted on one side of the housing 1, and the heat dissipation blade 7 is connected to the motor stator and rotor assembly 6.

[0026] It should be noted that, in this embodiment, by providing a heat dissipation blade 7 connected to the motor stator and rotor assembly 6 on one side of the housing 1, when the motor stator and rotor assembly 6 is running, the heat dissipation blade 7 can be driven to rotate, thereby accelerating the airflow inside the housing 1 and dissipating the heat generated by the motor more quickly, thus improving the heat dissipation efficiency.

[0027] In one embodiment, such as Figures 1 to 5 As shown, one side of one of the side-flowing water rings 10 is fixedly connected to an inlet pipe 8, and the other side of the side-flowing water ring 10 is fixedly connected to an outlet pipe 9. One end of the spiral cooling water pipe 19 and one end of the inlet pipe 8 are both fixedly connected to an inlet tank 12, and the other end of the spiral cooling water pipe 19 and one end of the outlet pipe 9 are both fixedly connected to an outlet tank 13.

[0028] It should be noted that in this embodiment, cooling water enters the spiral cooling water pipe 19 and the water inlet pipe 8 through the water inlet tank 12, enters the side water ring 10 through the water inlet pipe 8 for diversion treatment, and is discharged centrally through the water outlet tank 13 after heat exchange.

[0029] In one embodiment, such as Figures 1 to 5 As shown, a connecting pipe 14 is fixedly connected to one side of both the inlet tank 12 and the outlet tank 13, and an electrically controlled valve 15 is installed on the connecting pipe 14.

[0030] It should be noted that in this embodiment, a connecting pipe 14 is provided on one side of the inlet tank 12 and the outlet tank 13 and an electrically controlled valve 15 is installed. The flow rate and velocity of the cooling water can be adjusted by controlling the opening and closing of the electrically controlled valve 15.

[0031] In one embodiment, such as Figures 1 to 5 As shown, the fixing ring 16 has multiple through holes 17 inside.

[0032] It should be noted that in this embodiment, multiple through holes 17 are opened inside the fixing ring 16. On the one hand, this can reduce the weight of the fixing ring 16 and reduce the overall weight of the motor, which is beneficial to the installation and operation of the motor.

[0033] In one embodiment, such as Figures 1 to 5 As shown, multiple heat dissipation fins 2 are fixedly attached at equal intervals on the outer side of the casing 1. A connecting cover 4 is fixedly installed on the side of the casing 1 away from the rear cover 3 by bolts. A ventilation mesh 21 is provided inside the rear cover 3.

[0034] It should be noted that in this embodiment, multiple heat dissipation fins 2 are fixedly attached at equal intervals to the outer side of the housing 1, which can increase the heat dissipation area of ​​the housing 1, so that the heat generated by the motor can be dissipated to the surrounding environment more quickly, thereby improving the heat dissipation efficiency. The equal distribution of the heat dissipation fins 2 can make the heat dissipation more uniform and avoid local overheating.
