Abstract
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
Technical field：
The present invention relates to a kind of air-cooled cooling structure of magnetic suspension blower fan.
Background technology：
Existing magnetic suspension blower fan cooling is to arrange an independent cooling fan using afterbody to be cooled down, general blower fan
During work, caloric value can change with the change of power, but cooling air quantity is not yet if the rotating speed inconvenience of cooling fan
Can with power of fan change it is possible to when high-power cooling air quantity not, or cooling air quantity when power is little
Cross very much not energy-conservation.
Therefore, it is necessory to improve prior art to solve the deficiency of prior art.
Content of the invention：
The present invention is to provide a kind of magnetic suspension blower fan air-cooled cooling knot to solve the problems, such as above-mentioned prior art
Structure.
The technical solution adopted in the present invention has：A kind of air-cooled cooling structure of magnetic suspension blower fan, including casing, stator, turns
Son and bearing, described stator and two bearings are fixed in casing, and two bearings are symmetrically positioned in the both sides of stator, rotor rotating support
In stator and bearing, and the two ends of rotor stretch in outside casing, also include cooling duct, cooling fan and cover body,
Described cover body is fixed on the lower end of casing, and is formed with heat dissipation cavity between cover body and casing, and cooling fan is located at scattered
Hot intracavity and being fixedly connected with the bottom of rotor, cooling duct is fixed on cover body, and cooling duct is connected with heat dissipation cavity.
Further, described cooling duct is arc-shaped.
The present invention has the advantages that：The rotating speed of the cooling fan in the present invention is synchronous with rotor speed, cools down wind
The cooling air quantity of fan changes with the changed power of blower fan work, not only can guarantee that cooling air quantity but also energy-conservation.
Brief description：
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 air-cooled cooling structure of present invention magnetic suspension blower fan, including casing 1, stator 2, rotor 3, bearing
4th, cooling duct 5, cooling fan 6 and cover body 7, stator 2 and two bearings 4 are fixed in casing 1, and two bearings 4 are symmetrically positioned in
The both sides of stator 2, rotor 3 rotating support is in stator 2 and bearing 4, and the two ends of rotor 3 stretch in outside casing 1.Cover body 7 is fixing
In the lower end of casing 1, and between cover body 7 and casing 1, it is formed with heat dissipation cavity 10, the bottom of rotor 3 is placed in this heat dissipation cavity 10.Cold
But fan 6 is in heat dissipation cavity 10, and cooling fan 6 is fixedly connected with the bottom of rotor 3, and cooling duct 5 is fixed on cover body 7
On, and cooling duct 5 is connected with heat dissipation cavity 10.
Cooling duct 5 in the present invention is arc-shaped.
The present invention is provided with cooling fan 6 in the bottom of rotor 3, and rotor 3 rotates, and the heat in heat dissipation cavity 10 is via cooling wind
Pipe 5 is discharged.Power of fan becomes big, and the rotating speed of rotor 3 improves, because cooling air quantity is directly proportional to rotor speed, cools down wind
Amount also can improve；Power of fan becomes hour, and rotor speed reduces, and cooling air quantity reduces in the same manner, reducing energy consumption.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for 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.
