Description

A kind of magnetic suspension air blower air-cooled structure

Technical field:

The present invention relates to a kind of magnetic suspension air blower air-cooled structure.

Background technology:

Existing magnetic suspension air blower cooling mainly adopts water-cooling pattern, it is desirable to the good airproof performance of pipeline, regularly replaces cold But liquid, safeguards inconvenient.

Therefore, it is necessory to improve to prior art to solve the deficiency of prior art.

Content of the invention:

The present invention is to provide a kind of magnetic suspension air blower air-cooled structure to solve the problems, such as above-mentioned prior art.

The technical solution adopted in the present invention has:A kind of magnetic suspension air blower air-cooled structure, including casing, stator, rotor, Magnetic bearing and spiral case, the spiral case is fixed on the top of casing, and stator and two magnetic bearings are fixed in casing, and two magnetic bearings pair Claim positioned at the both sides of stator, rotor rotating support is in stator and magnetic bearing, and the upper end of rotor is stretched in spiral case, is also included cold But airduct, cooling fan and cover body, the cover body is fixed on the lower end of casing, and is formed with radiating between cover body and casing Chamber, cooling fan is located at radiating intracavity, and cooling duct is fixed on cover body, and cooling duct is connected with heat dissipation cavity;

The side wall of the casing is provided with air inlet, and the air inlet is Wei Yu stator and spiral case between, in the bottom of casing Wall is provided with air outlet, and inner chamber of the heat dissipation cavity by the air outlet with casing connects.

Further, the outer wall of the casing is provided with radiation tooth.

The present invention has the advantages that:The present invention install, easy to maintenance, sealing requirements are low.

Description of the drawings:

Fig. 1 is present configuration figure.

Specific embodiment:

The present invention is further illustrated below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of magnetic suspension air blower air-cooled structure of the present invention, including casing 1, stator 2, rotor 3, magnetic bearing 4 and spiral case 9, spiral case 9 is fixed on the top of casing 1, and stator 2 and two magnetic bearings 4 are fixed in casing 1, and two magnetic bearings 4 are symmetrical Positioned at the both sides of stator 2,3 rotating support of rotor is in stator 2 and magnetic bearing 4, and the upper end of rotor 3 is stretched in spiral case 9.In machine The lower end of shell 1 is fixedly connected with cover body 7, is formed with heat dissipation cavity 10 between cover body 7 and casing 1, and the lower end of rotor 3 stretches in the radiating In chamber 10.Cooling fan 6 is in heat dissipation cavity 10, and cooling duct 5 is fixed on cover body 7, and cooling duct 5 and 10 phase of heat dissipation cavity Connection.

Air inlet 11 is provided with the side wall of casing 1, and the air inlet 11 is Wei Yu stator 2 and spiral case 9 between, in casing 1 Base end wall be provided with air outlet 12, heat dissipation cavity 10 is connected by the air outlet 12 and the inner chamber of casing 1.

Radiation tooth 100 is provided with the outer wall of casing 1.

Magnetic suspension air blower radiating in the present invention is divided into external cooling and internal heat dissipating.External cooling is mainly using empty The mode of 100 convection current of radiation tooth on the outer wall of gas and casing 1.

Internal heat dissipating is cooled down using 1 internal forced ventilation of casing, because aerator is operationally, the temperature height of spiral case 9 In casing 1, heat can be conducted to casing 1, so the air inlet 11 in casing 1 at spiral case 9 can be taken away a part of spiral case 9 and pass The heat that leads, while the heat of the stator inner surface, rotor outer surface and magnetic bearing surface in 1 inside of casing can be also taken away, solely Vertical cooling fan 6 is arranged on the lower end of casing 1, and casing 1 discharged by the cooled fan 6 of the air after heat exchange.

The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's Protection domain.
