Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet motors, in particular to a water-cooled casing of a permanent magnet motor. Background Art

[0002] The permanent magnet motor is a hybrid permanent magnet motor with a rectangular pulse wave, a sine wave current, and a permanent magnet motor. After the permanent magnet motor is manufactured, it can maintain its magnetic field without external energy. The permanent magnet motor rotor is equipped with permanent magnet poles. The permanent magnet motor is usually used in low-power applications. The water-cooled casing is a casing used to cool the permanent magnet motor, which can effectively reduce the operating temperature of the permanent magnet motor and improve the performance and reliability of the equipment. The water-cooled casing uses a different technology from the traditional heat dissipation method. By combining electronic equipment with a water cooling system, it can absorb and conduct heat more effectively. Compared with the air cooling method, the water-cooled casing can provide a larger heat dissipation area, thereby dissipating heat from the permanent magnet motor more quickly. The water-cooled casing can more efficiently take away the heat by using a water cooling system, so that the temperature of the permanent magnet motor can be kept within a reasonable range. The water-cooled casing does not require a fan during the heat dissipation process, so it can help reduce noise. The water-cooled casing can not only dissipate heat through the water cooling system, but also further increase the heat dissipation capacity by expanding the heat dissipation device. Users can choose to add additional heat dissipation devices such as heat sinks and heat pipes according to actual needs to meet higher heat dissipation requirements.

[0003] As shown in application number CN201820637346.6, the utility model provides a motor water-cooling casing with excellent heat dissipation effect and convenient processing and manufacturing. A motor water-cooling casing includes an outer shell, an inner shell, a mounting block and a circulating water pipe. The outer shell is sleeved on the outside of the inner shell, and the mounting block is arranged on the outer surface of the inner shell near the end. The outer shell is fixedly connected to the inner shell through the mounting block. The circulating water pipe is spirally wound on the outer surface of the inner shell and fixedly connected to the inner shell. The outer surface of the outer shell is provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected to the circulating water pipe. A potting glue for filling the gap is provided between the inner shell and the outer shell. The utility model adopts a spiral circulating water circuit with low hydraulic loss, and has good heat dissipation effect in combination with the fins outside the water pipe; the closed pipeline adopted has no cross-flow and leakage phenomenon; the shell diameter and length can be quickly changed according to different needs, and the manufacturing flexibility is large; the processing is simple and convenient, the processing amount is small, and the manufacturing cost is low.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] When the water in the existing device comes into contact with heat, the temperature of the water will rise, and the water needs to be constantly replaced, which is troublesome, and the cooling effect is relatively poor.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a permanent magnet motor water-cooling casing is proposed, in order to achieve a more practical purpose. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a permanent magnet motor water-cooled casing, comprising a support base and a cooling rod, the surface of the support base is provided with bolt holes, and a water-cooled casing body is fixed to the upper end of the support base, a connecting through hole begins to be provided on the front end surface of the water-cooled casing body, the cooling rod is passed through the inside of the connecting through hole, an electric power ring is provided at the front end of the cooling rod, and a switch button is installed on the surface of the electric power ring.

[0009] Furthermore, a water-cooling casing inner cavity is provided inside the water-cooling casing body, and a connecting shell is provided at the rear end of the water-cooling casing body.

Through the socket connection between the connecting through hole 8 and the cooling rod 9, the cooling rod 9 can be placed in the interlayer of the water-cooled casing body 3. At the same time, the water-cooled casing body 3 has good cooling performance, and the cold air generated by the cooling rod 9 can be evenly laid in the water-cooled casing body 3, thereby cooling the water in the water-cooled casing body 3 and improving the cooling efficiency.

[0027] Implementation 2:

[0028] like Figure 4 and Figure 5 As shown, a filter screen 12 is installed inside the processing box 10, and an activated carbon plate 13 is arranged on the left side of the filter screen 12. Furthermore, a connecting plate 4 is arranged at the bottom end of the water-cooling case body 3, and a positioning suction cup 14 is installed at the bottom end of the connecting plate 4. Furthermore, two positioning suction cups 14 are arranged, and the connecting plate 4 is rectangular, which is convenient for water intake and pumping through the connecting pipe mouth 11. When water enters the processing box 10, it passes through the filter screen 12 and the activated carbon plate 13 in turn, which can intercept impurities in the water and remove odors from the water, avoid impurities in the water from accumulating inside the water-cooling case body 3, avoid clogging the water-cooling case body 3, and prevent the water intake of the water-cooling case body 3 from being reduced.
