Description

Technical Field

[0001] The present invention belongs to the technical field related to water cooling and heat dissipation, and more specifically, relates to a water cooling and heat dissipation brushless motor with high-efficiency dual-circulation function. Background Art

[0002] The motor does generate heat during operation, which is mainly caused by the resistance loss generated when the current passes through the motor winding, the hysteresis and eddy current loss in the iron core, as well as mechanical friction and wind resistance. If this heat cannot be dissipated in time, it will have many negative effects on the motor. As the temperature rises, the electrical parameters such as the resistance and inductance of the motor will change, resulting in reduced motor efficiency and power factor, which will cause aging of motor components and motor failure.

[0003] Existing water circulation systems may adopt fixed circulation modes and heat dissipation methods, and cannot be flexibly adjusted according to the actual heating conditions of the motor. As a result, when the motor heats up, the water circulation system has excess heat dissipation capacity, causing energy waste. When the motor heats up, the heat dissipation capacity is insufficient, and it cannot effectively cool down and cannot be dynamically adjusted according to the heat level of the motor.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a water-cooled brushless motor with high-efficiency dual-circulation function is provided to achieve a more practical purpose. Utility Model Content

[0047] Specific usage of this utility model:

[0048] When the motor 12 is in use, it generates heat, and the motor 12 transfers the heat to the heat-conducting block 29. The heat-conducting block 29 contacts the hose 33, causing the liquid in the hose 33 to vaporize, the pressure in the hose 33 to increase, and the hose 33 to deform, pushing the annular plate 31 to slide. The annular plate 31 pushes the first slider 30 and the first slider 30 to slide. The annular plate 31 pushes the push rod 49 while pushing the fifth slider 44 to slide. At the same time, the sixth slider 45 will also slide. The sixth slider 45 squeezes the fourth spring 46, and the distance between adjacent sixth sliders 45 is reduced. The distance between adjacent coolant pipes 51 is reduced, and the contact time and area between the motor 12 and the coolant are increased, thereby improving the heat dissipation efficiency. When the distance between the sixth sliders 45 is reduced, the ring 50 slides on the surface of the motor 12, and the third slider 42 slides inward. The sliding shaft 40 slides inward, and can be adjusted according to the potholes on the surface of the motor 12. To adjust the angle of the bracket, so that the contact between the coolant pipe 51 and the motor 12 is better, and the heat dissipation effect is better achieved. When the push rod 49 slides, the water inlet pipe 28 is also pushed. At the same time, the position of the coolant tank 17 changes, the position of the telescopic rod 25 changes, the telescopic rod 25 contacts the convex ring 37, the convex ring 37 rotates, the telescopic rod 25 slides on the convex ring 37, and the telescopic rod 25 pushes the swing plate 24. The further the coolant tank 17 moves forward, the greater the degree of telescopic extension of the telescopic rod 25, and the greater the swing amplitude of the swing plate 24, which accelerates the flow rate of the coolant, improves the heat dissipation effect of the motor, and better ensures the long-term use of the motor. The liquid flows out from the water inlet pipe 28, passes through the coolant pipe 51, and then flows into the water outlet pipe 27, and finally flows into the liquid cavity 26 through the water inlet 21. Under the action of gravity, the liquid flows downward and passes through multiple condensation plates 20 for cooling, achieving the effect of water circulation cooling.
