Description

Technical Field

[0001] The present invention relates to the technical field of generators, and specifically to a permanent magnet generator with a housing heat dissipation mechanism. Background Art

[0002] A permanent magnet generator is a generator that uses permanent magnets to generate a magnetic field. Due to its advantages such as high efficiency, energy conservation, low carbon, large power, and small volume, it is widely used in fields such as household appliances, medical devices, automobiles, aviation, and national defense.

[0003] During the use of a permanent magnet generator, a large amount of heat is generated. If this heat cannot be discharged in time, it will affect the normal operation of the generator, and in severe cases, it may cause damage to the permanent magnet generator. The heat dissipation method of the permanent magnet generator in the prior art is to dissipate heat through a single method of water cooling or air cooling, and it cannot meet the heat dissipation requirements of the permanent magnet generator in some relatively harsh environments. It is not possible to combine the two on the basis of water cooling and use air cooling to assist in dissipating heat inside it, further improving the heat dissipation effect and efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, with the following advantages: 1.

At the same time, a mating rotating shaft is installed on the water cooling circulation pipe, and a heat dissipation fan blade is arranged on the mating rotating shaft.

[0017] 3. Additionally, when installing the mating rotating shaft, insert the cross block into the cross connection groove, which can achieve the fixed connection between the mating rotating shaft and the first rotating shaft. At the same time, under the action of the mating rotating shaft, the first movable ring will be pushed upward, and then under the action of the first movable ring, the plug-in fixing plate will be inserted into the positioning plug-in cavity to achieve the fixed installation of the water-cooled circulation pipe.

[0043] When the motor is working, the water pump 24 also works synchronously, pumping the water in the water tank 21 through the condenser 25 into the water cooling circulation pipe 3. As the cooling water flows, the heat inside the motor can be absorbed and carried out. At the same time, under the action of the water flow, the first rotating blade 41 will be driven to rotate. As the first rotating blade 41 rotates, the first rotating shaft 4 will also be driven to rotate, and then the mating rotating shaft 6 will be driven to rotate. In this way, the cooling fan blade 61 can be rotated, so that air-cooled heat dissipation can be carried out synchronously. In addition, under the action of the water flow, the second rotating blade 831 will be pushed to rotate. As the second rotating blade 831 rotates, the pushing contact plate 81 will also be driven to rotate. During the rotation of the pushing contact plate 81, it will contact the adjacent mating driving plate 93. In this way, under the action of the pushing contact plate 81, the mating driving plate 93 will be pushed to move, so that the movable cover plate 9 no longer covers the heat dissipation holes 28, and the heat dissipation holes 28 are opened, facilitating the discharge of the heat inside the motor. When the motor is not dissipating heat, the movable cover plate 9 covers the heat dissipation holes 28, which can effectively prevent external dust from entering the inside of the motor housing 2. In this way, under the combined heat dissipation effect of air-cooling and water-cooling, the inside of the motor can be well dissipated, ensuring that the heat dissipation requirements can be met. In addition, when installing the water cooling circulation pipe 3 and the mating rotating shaft 6, the connecting socket pipe 31 on the water cooling circulation pipe 3 is inserted into the connecting pipe groove 23 to realize the sealed connection of the water cooling circulation pipe 3 with the return water pipe 22 and the water outlet pipe 26. Then, the mating rotating shaft 6 is installed, that is, the cross block 63 on the mating rotating shaft 6 is inserted into the cross connection groove 44. Push the mating rotating shaft 6 upward. During the upward push, the locking card plate 76 will contact the inclined surface driving platform 43. In this way, under the action of the inclined surface driving platform 43, the locking card plate 76 will be pushed to move. At the same time, under the action of the connecting hinge rod 73, the second movable ring 7 will be driven to move upward relative to the mating rotating shaft 6 until the locking card plate 76 passes over the inclined surface driving platform 43, and then it is reset, so that the locking card plate 76 is lapped on the upper end of the inclined surface driving platform 43, realizing the fixed connection between the first rotating shaft 4 and the mating rotating shaft 6. When the mating rotating shaft 6 moves upward, the contact runner 69 contacts the first movable ring 5, and it will push the first movable ring 5 upward. As the first movable ring 5 moves upward, under the action of the mating connecting rod 53, the supporting positioning plate 54 will be pushed to move, so that the plugging fixing plate 55 on the supporting positioning plate 54 is inserted into the corresponding positioning plugging cavity 29, realizing the multi-point fixing of the water cooling circulation pipe 3, which is very convenient and fast.
