Problems solved by technology
[0004] The existing maglev fan is cooled by setting an independent cooling fan at the rear. Generally, the heat generated by the fan will change with the power when it is working, but if the speed of the cooling fan is inconvenient, the cooling air volume will not change with the fan power. Changes, the cooling air volume may not be enough when the power is high, or the cooling air volume is too large when the power is low, which will not save energy

The invention discloses an air cooling structure of a magnetic suspension draught fan. The air cooling structure comprises a machine shell, a stator, a rotor and bearings, wherein the stator and the two bearings are fixed in the machine shell, the two bearings are located on the two sides of the stator symmetrically, the rotor is rotationally supported in the stator and the bearings, and the two ends of the rotor extend out of the machine shell. The air cooling structure further comprises a cooling air hose, a cooling fan body and a housing. The housing is fixed to the lower end of the machine shell, a heat dissipation cavity is formed between the housing and the machine shell, the cooling fan body is arranged in the heat dissipation cavity and fixedly connected with the bottom end of the rotor, the cooling air hose is fixed to the housing and communicates with the heat dissipation cavity. According to the air cooling structure, the rotation speed of the cooling fan body is synchronous with that of the rotor, the cooling capacity of the cooling fan body changes along with changes of the working power of the draught fan, the cooling capacity can be ensured, and energy can be saved.
Description
[0001] Technical field: [0002] The invention relates to an air-cooled cooling structure of a magnetic levitation fan. [0003] Background technique: [0004] The existing maglev fan is cooled by setting an independent cooling fan at the rear. Generally, the heat generated by the fan will change with the power when it is working, but if the speed of the cooling fan is inconvenient, the cooling air volume will not change with the fan power. The cooling air volume may not be enough when the power is high, or the cooling air volume is too large when the power is low, which will not save energy. [0005] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. [0006] Invention content: [0007] The present invention provides an air-cooled cooling structure of a magnetic levitation fan in order to solve the above-mentioned problems in the prior art. [0008] The technical solution adopted in the present invention includes: an air-cooled c...
