Wall is provided with air outlet, and heat dissipation cavity is connected by the air outlet with the inner chamber of casing.
Further, the outer wall of the casing is provided with radiation tooth.
The utility model has the advantages that：The utility model install, it is easy to maintenance, sealing requirements are low.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of magnetic suspension air blower air-cooled structure of the utility model, including casing 1, stator 2, rotor 3, magnetic
Bearing 4 and spiral case 9, spiral case 9 are fixed on the top of casing 1, and the magnetic bearing 4 of stator 2 and two is fixed in casing 1, and two magnetic bearings 4
It is symmetrically positioned in the both sides of stator 2, the rotating support of rotor 3 is in stator 2 and magnetic bearing 4, and the upper end of rotor 3 is stretched in spiral case 9.
Cover body 7 is fixedly connected with the lower end of casing 1, heat dissipation cavity 10 is formed between cover body 7 and casing 1, the lower end of rotor 3 stretches in this
In heat dissipation cavity 10.In heat dissipation cavity 10, cooling duct 5 is fixed on cover body 7 cooling fan 6, and cooling duct 5 and heat dissipation cavity
10 are connected.
Air inlet 11 is provided with the side wall of casing 1, and the air inlet 11 is located between stator 2 and spiral case 9, 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 utility model is divided into external cooling and internal heat dissipating.External cooling is mainly to be adopted
With the mode of the convection current of radiation tooth 100 on the outer wall of air and casing 1.
Internal heat dissipating is cooled down using the internal forced ventilation of casing 1, because air blower is operationally, the temperature of spiral case 9 is high
In casing 1, heat can conduct to casing 1, so the air inlet 11 on casing 1 at spiral case 9 can take away a part of spiral case 9 and pass
The heat led, while the heat of the stator inner surface, rotor outer surface and magnetic bearing surface in the inside of casing 1 can be also taken away, solely
Vertical cooling fan 6 is arranged on the lower end of casing 1, and the air after heat exchange discharges casing 1 through cooling fan 6.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
Protection domain of the present utility model.
