Description
Technical Field
[0001] This utility model relates to the technical field of brushless motors, and in particular to a high-efficiency heat-dissipating brushless AC / DC motor. Background Technology
[0002] A brushless AC / DC motor is a type of brushless DC motor. It is a high-efficiency motor that uses DC power and replaces mechanical commutation with electronic commutation. It is an upgraded version of the traditional brushed DC motor and is widely used in automation, new energy, consumer electronics and other fields. Although brushless DC motors are more efficient than traditional brushed motors, they still generate a lot of heat and need to be cooled during operation. Therefore, a high-efficiency heat-dissipating brushless AC / DC motor is particularly needed.
[0003] However, most existing brushless AC and DC motors have poor heat dissipation performance. When working, the heat cannot be dissipated quickly, which will seriously affect the performance, lifespan and even pose safety hazards.
[0004] To address the aforementioned issues, a search revealed a novel brushless DC motor disclosed in patent CN110492648B. The patent states that "a brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. The stator windings of the motor are often made in a three-phase symmetrical star connection, very similar to a three-phase asynchronous motor. However, this type of motor is very time-consuming and labor-intensive to install and move, inconvenient to adjust, and cannot change the rotation angle." This novel brushless DC motor, by removing the second support arm from the platform and then removing the connecting rod from the rectangular groove, causes the first support arm on the first movable rod to rotate outwards. The rotating buckle on the slider passes through the second support arm. The rectangular through-hole on the arm is rotated and locked. The position of the slider is adjusted by the position of the buckle in the round hole, so that the anti-collision cotton and the motor can directly contact each other, and the motor is fixedly fixed on the base plate, which facilitates the installation of the brushless DC motor. This new type of brushless DC motor allows the transmission rod to rotate inside the limit frame by rotating the fixing ring. The rotation of the transmission rod drives the transmission gear to move the lifting rod within the limit frame, thereby adjusting the height of the anti-slip foot. The brushless DC motor can be moved directly without disassembly. It can also be rationally adjusted according to the terrain or connection angle, making the brushless DC motor more practical. However, the heat dissipation of the brushless DC motor is poor, and heat will affect its performance and service life.
[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency heat-dissipating brushless AC / DC motor, including a brushless motor 1, a mounting base 2 fixedly mounted on the lower surface of the brushless motor 1, a protective shell 3 fixedly mounted on the upper surface of the mounting base 2, a water tank 4 fixedly mounted on one side surface of the mounting base 2, a water inlet pipe 5 provided at one end of the water tank 4, a water pump 6 fixedly mounted on the upper surface of the water tank 4, a water pump 7 fixedly connected to the input end of the water pump 6, a water delivery pipe 8 fixedly connected to the output end of the water pump 6, and a heat dissipation water pipe 9 fixedly connected to the other end of the water delivery pipe 8. A return water pipe 10 is fixedly connected to the outer wall of the supply water pipe 8, and a first connecting plate 13 is fitted on the outer wall of the supply water pipe 8. A rubber gasket 14 is adhered to the inner wall of the first connecting plate 13. A first fixing plate 15 is fixedly installed at both ends of the first connecting plate 13. A second connecting plate 16 is fitted on the outer wall of the supply water pipe 8, and a second fixing plate 17 is fixedly installed at both ends of the second connecting plate 16. Bolts 18 are provided at both ends of the first fixing plate 15, and a nut 19 is threaded onto one end of each bolt 18. The supply water pipe 8 is connected to the brushless motor 1, mounting base 2, protective shell 3, water tank 4, inlet water pipe 5, water pump 6, suction pipe 7, supply water pipe 8, and cooling water pipe. The following components are included: 9. Return water pipe; 10. Heat dissipation fins; 11. Heat dissipation fan; 12. First connecting plate; 13. Rubber pad; 14. First fixing plate; 15. Second connecting plate; 16. Second fixing plate; 17. Bolt; 18. Nut; 19. When the brushless motor 1 is working, the water pump 6 draws cold water from the water tank 4 through the suction pipe 7, and then sends the cold water to the heat dissipation pipe 9 through the delivery pipe 8. As the cold water flows in the heat dissipation pipe 9, it absorbs the heat generated by the brushless motor 1 and carries the heat out of the protective shell 3, maintaining a low-temperature environment inside the protective shell 3. This keeps the brushless motor 1 at a low temperature, preventing the effects of high temperatures. The performance and service life of the brushless motor 1 are as follows: When the water flow brings the temperature back to the water tank 4, the heat dissipation fins 11 absorb the temperature in the water tank 4 and dissipate it. The cooling fan 12 can assist the heat dissipation of the heat dissipation fins 11. The water in the water tank 4 can always be kept at a low temperature and circulate for heat dissipation. When heat dissipation is carried out, the first connecting plate 13 and the second connecting plate 16 are attached to the connection between the water supply pipe 8 and the heat dissipation pipe 9 and fixed with bolts 18 and nuts 19 to ensure the sealing of the connection between the water supply pipe 8 and the heat dissipation pipe 9 and prevent water leakage.
[0019] Furthermore, the two ends of the water pump 7 are fixedly connected to the water tank 4 and the input end of the water pump 6, respectively. Through the water pump 7, the water pump 6 can draw out the cold water in the water tank 4 through the water pump 7, so that the cold water can enter the cooling water pipe 9.
[0020] Furthermore, the two ends of the cooling water pipe 9 are fixedly connected to the water supply pipe 8 and the return water pipe 10, respectively. The two ends of the return water pipe 10 are fixedly connected to the cooling water pipe 9 and the water tank 4, respectively. Through the setting of the cooling water pipe 9, the cold water can absorb the heat generated by the brushless motor 1 when it flows in the cooling water pipe 9, which plays a role in cooling the brushless motor 1.
[0021] Furthermore, a heat dissipation fin 11 is fixedly installed on one side surface of the water tank 4, and a cooling fan 12 is fixedly installed on one side surface of the heat dissipation fin 11. Through the arrangement of the heat dissipation fin 11, the heat dissipation fin 11 can conduct heat out of the water tank 4 and dissipate heat, so that the water in the water tank 4 is always kept at a low temperature.
[0022] Furthermore, three sets of cooling fans 12 are installed at equal intervals on one side surface of the heat dissipation fins 11. Through the arrangement of the cooling fans 12, the cooling fans 12 can blow away the heat on the heat dissipation fins 11, thereby improving the heat dissipation effect on the water tank 4.
[0023] Furthermore, rubber gaskets 14 are adhered to the inner walls of both the first connecting plate 13 and the second connecting plate 16. The rubber gaskets 14 improve the sealing of the connection between the water supply pipe 8 and the heat dissipation pipe 9.
[0024] Furthermore, both the first fixing plate 15 and the second fixing plate 17 have through holes. One end of the bolt 18 passes through the first fixing plate 15 and the second fixing plate 17 and is threadedly connected to the nut 19. Through the setting of the bolt 18 and the nut 19, the bolt 18 and the nut 19 can fix the first fixing plate 15 and the second fixing plate 17 together, thereby fixing the first connecting plate 13 and the second connecting plate 16 together.
[0025] Working principle: When the brushless motor 1 is working, the water pump 6 draws cold water from the water tank 4 through the water pipe 7, and then sends the cold water to the cooling water pipe 9 through the water supply pipe 8. When the cold water flows in the cooling water pipe 9, it absorbs the heat generated by the brushless motor 1 and carries the heat out of the protective shell 3, keeping the protective shell 3 at a low temperature. This keeps the brushless motor 1 at a low temperature, preventing high temperatures from affecting the performance and service life of the brushless motor 1. Secondly, when the water flow brings the temperature back to the water tank 4, the heat dissipation fins 11 absorb the temperature in the water tank 4 and dissipate it. The cooling fan 12 can assist the heat dissipation of the heat dissipation fins 11. The water in the water tank 4 can always be kept at a low temperature and circulate for heat dissipation. During the heat dissipation process, the first connecting plate 13 and the second connecting plate 16 are attached to the connection between the water supply pipe 8 and the cooling water pipe 9 and fixed with bolts 18 and nuts 19 to ensure the sealing of the connection between the water supply pipe 8 and the cooling water pipe 9 and prevent water leakage.
