Cooling structure of rotor of air blower

Abstract

The invention discloses a cooling structure of a rotor of an air blower. The cooling structure comprises a stator, the rotor, a machine shell, an air inlet channel, an impeller and a guiding cone, wherein the impeller and the guiding cone are installed together. The stator is arranged in the machine shell. The rotor is rotatably arranged in the stator. The top end of the rotor is connected with the impeller. The air inlet channel is fixedly connected with the machine shell. The cooling structure further comprises a heat dissipation rod, inner heat dissipation pieces, outer heat dissipation pieces and a support. The support is fixedly connected in the air inlet channel. A heat dissipation hole is formed in the rotor in the axial direction. A through hole aligned with the heat dissipation hole is formed in the guiding cone in the axial direction. The heat dissipation rod is arranged in the heat dissipation hole and the through hole. The top end of the heat dissipation rod stretch out of the through hole and is fixedly connected with the support. The multiple inner heat dissipation pieces are fixedly connected to the lower section of the heat dissipation rod in a layered mode. All the inner heat dissipation pieces are located in the heat dissipation hole. The outer heat dissipation pieces are fixedly connected to the upper section of the heat dissipation rod, and the outer heat dissipation pieces are located in the air inlet channel. The heat dissipation hole of the rotor is filled with heat guiding liquid. According to the cooling structure, the rotor cooling effect is good, the structure is simple, manufacturing is convenient, and loading and unloading are convenient.

Description

Technical field: [0001] The invention relates to a cooling structure for a blower rotor, which belongs to the technical field of blowers. Background technique: [0002] The rotor cooling of existing blowers generally adopts air-cooling and liquid-cooling methods. The blower using air-cooling method consumes a lot of power. Steam infiltration, so the insulation, chemical corrosion resistance, and corrosion resistance of the internal parts of the motor are very high, and the casing must also be airtight. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present invention provides a cooling structure for a blower rotor in order to solve the above-mentioned problems in the prior art. [0005] The technical solution adopted in the present invention includes: a cooling structure for the blower rotor, including a stator, a rotor, a casing, an air inlet, an impeller, and a diversion cone insta...

Problems solved by technology

[0002] The rotor cooling of existing blowers generally adopts air-cooling and liquid-cooling methods. The blower using air-cooling method consumes a lot of power, and the liquid-cooling method will cause the cooling liquid to splash out from the surface of the rotor. Steam infiltration, so the insulation, chemical corrosion resistance and corrosion resistance requirements of the internal parts of the motor are very high, and the casing must also be airtight
