Description
Technical field
The present invention relates to a kind of fan, particularly a kind of for the fan to electronic element radiating.
Background technique
At present, fan design obtains more and more thinner, and performance is more and more higher, is widely used in notebook computer.Traditional fan comprises a wheel hub and is located on some flabellums of this hub periphery edge.The annular sidewall that this wheel hub comprises a circular bottom wall and extended to form downwards by the periphery of this diapire.One toroidal magnet magnetic absorption is on the internal surface of the sidewall of this wheel hub.For preventing, between magnet and wheel hub, relative displacement occurs, gum down between magnet and wheel hub.The cost of centrifugal fan is general higher, and the magnetic of magnet is easier to occur extremely.Once the magnetic of magnet occurs abnormal, need magnet to dismantle to change magnet from wheel hub.But the magnet after assembling dismantles being difficult to from wheel hub, so once quality problems appear in the magnet in wheel hub, whole fan will be scrapped.
Summary of the invention
In view of this, be necessary to provide a kind of easy dismounting, fan easy to maintenance.
A kind of fan, comprise an impeller, one rotating shaft and a toroidal magnet, this impeller comprises a wheel hub and is located at some flabellums of this wheel hub periphery, the sidewall that this wheel hub comprises roof and extended by roof, this rotating shaft is fixed on this wheel hub roof central authorities, this magnet is contained in this wheel hub and to be surrounded on this rotating shaft peripheral, this magnet is installed on the sidewall of this wheel hub, the roof place of this wheel hub offers and one or morely disassembles hole, described one or more position of disassembling hole is corresponding with the position of this magnet being positioned at this wheel hub, make this magnet through the one or more holes of disassembling on this wheel hub roof to exposing outside.
Compared with prior art, magnet in fan of the present invention is once magnetic occurs abnormal, a downward pressure can be applied through this one or more hole of disassembling to the magnet in this wheel hub with tool, so that magnet is dismantled from wheel hub, magnet on wheel hub can be replaced again, fan can also be reused, and is unlikely to because the magnetic of magnet occurs extremely causing whole fan to scrap.

Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 to Fig. 4, the fan 100 being used for dispelling the heat to heat-generating electronic elements of a preferred embodiment of the present invention, comprises impeller 10, rotating shaft 20 and a toroidal magnet 30.In the present embodiment, this fan 100 is one for the centrifugal fan of notebook computer.
This impeller 10 comprises a wheel hub 12, is located on the disk 14 of an annular of these wheel hub 12 outer periphery and is located at these disk about 14 both sides and disperses some circular arc flabellums 16 of arrangement along this disk 14 periphery.
This wheel hub 12 generally uses cold-rolled carbon steel plate by SPCC() or the sub-plumbous galvanized steel plain sheet of SECC(electrolysis) material makes.The annular sidewall 124 that this wheel hub 12 comprises a circular top wall 122 and extended to form downwards by the periphery of this roof 122.
This disk 14 offers a circular fixation hole 142 and multiple vent hole 144 around this fixed hole 142.The diameter of this fixed hole 142 equals the diameter of this wheel hub 12, wears this fixed hole 142 be fixedly connected with this disk 14 to make this wheel hub 12.
One end of this rotating shaft 20 is fixed on roof 122 centre of described wheel hub 12.
The material of this magnet 30 is neodymium-iron-boron magnetic material.This magnet 30 is contained in this wheel hub 12, and it is peripheral to be surrounded on this rotating shaft 20.This magnet 30 magnetic sticker invests on the internal surface of sidewall 124 of wheel hub 12.For preventing, between magnet 30 and wheel hub 12, relative displacement occurs, gum down fixing between magnet 30 and wheel hub 12.
The edge of the roof 122 of this wheel hub 12 offers and one or morely disassembles hole 126.When disassembling hole 126 for time multiple, the plurality ofly disassemble the edge that hole 126 is circumferentially distributed in roof 122.These are one or more, and to disassemble the position in hole 126 corresponding with the position of this magnet 30 being positioned at this wheel hub 12.Disassemble hole 126 through one or more on this wheel hub 12 roof 122, expose the part-structure of this magnet 30.
Once the magnetic of this magnet 30 occurs abnormal, one or more hole 126 to apply separation magnet 30 and wheel hub 12 pressure to the magnet 30 in this wheel hub 12 can be disassembled, to be dismantled from wheel hub 12 by magnet 30 with tool through this.Like this, the magnet 30 on wheel hub 12 can be replaced again, and fan 100 can also be reused, and is unlikely to because the magnetic of magnet 30 occurs extremely causing whole fan 100 to scrap.
In the present embodiment, this shape disassembling hole 126 is for circular, and number is 3, and circumferentially equally spaced distributes in the edge of the roof 122 of this wheel hub 12.
Understandably, this shape disassembling hole can for arc, at the edge of the roof 122 of this wheel hub 12 circumferentially, makes tool pass this arc and disassembles hole and increase the force area of this wheel hub 12 inner magnet 30.
Understandably, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
