Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a compact and efficient heat dissipation water pump structure. Background Art

[0002] Water pumps generate heat during operation, especially high-power pumps or those operating continuously for extended periods. Traditional cooling water pumps often have complex structures and take up a lot of space. This not only increases installation cost and difficulty, but also results in unsatisfactory heat dissipation efficiency in some applications. Therefore, a compact cooling water pump is needed.

[0003] In the prior art, utility model patent number CN202420017033.6 discloses a water-cooled heat-dissipating drainage pump. Its motor includes an inner rotor and an outer stator. The main housing is provided with a rotor mounting cavity for mounting the inner rotor and a water injection cavity for injecting water for cooling. The inner rotor is mounted in the rotor mounting cavity. The outer stator includes a stator core and a stator winding. The stator core includes a magnetic pole portion wrapped around the outer wall of the rotor mounting cavity and a winding portion for mounting the stator winding. The water injection cavity is spaced outside the outer wall of the rotor mounting cavity. The stator magnetic pole accommodating area is formed between the outer wall of the water injection cavity and the outer wall of the rotor mounting cavity. The magnetic pole portion is placed in the stator magnetic pole accommodating area, and the water injection cavity is wrapped around the outer wall of the magnetic pole portion. When the drainage pump is draining water, water flows into the water injection cavity, dissipating heat from the outer stator, resulting in excellent heat dissipation performance.

[0004] The above patent provides a drainage pump with a compact structure and a heat dissipation structure. However, the device wraps a water injection chamber on the outside of the stator and dissipates heat to the outside of the stator through the coolant inside the water injection chamber. However, during the heat dissipation process, water vapor will condense on the contact surface between the hot air and the cold air, causing water droplets to adhere to the surface of the stator, which can easily cause damage to the motor. Further improvement is needed. Utility Model Content

[0037] In summary, the present invention sets a heat-conducting sleeve 7 on the outer surface of the motor stator 6, and then winds the cooling pipe 803 in the water cooling device 8 around the outer surface of the heat-conducting sleeve 7 to dissipate heat. At the same time, there is a high temperature difference only on the contact surface between the cooling pipe 803 and the heat-conducting sleeve 7, which will condense water droplets, thereby avoiding water droplets contacting the motor stator 6.
