Description

Oil bearing fan device
Technical field
The invention provides a kind of oil bearing fan device, espespecially a kind ofly reduce wear and reduce running noise and vibration and improve the oil bearing fan device in working life.
Background technique
Press, the electronics information product (such as: use computer etc.) is increasingly universal and use more extensive, to drive the technical development of electronics IT industry rapid due to demand, impel the electronics information towards carrying out the trend development that arithmetic speed promotes, access capability increases, cause the spare part in the aforementioned electronic information product often to have high temperature to supervene in working at high speed.
Take host computer as example, the heat that its center of inside processing unit (CPU) produces accounts for major part, in addition, central processing unit when heat gradually rising can cause and carry out usefulness and reduce, and when accumulation of heat during higher than its allowable limit, will force computer to work as machine, severe patient more may cause the damage phenomenon; And, for solving the problem of electromagenetic wave radiation, usually seal this host computer with the cabinet housing, so that how the heat energy of central processing unit and other heating spare part (or claiming element) is derived fast, become an important topic.
And general central processing unit arranges radiator and radiation fan above it in order to what the mode that solves heat radiation was taked, one side of radiator has been set up some fins, with the surface of the opposite side (not having fin) of described radiator directly the aforementioned central processing unit of contact making heat energy can conduct to above-mentioned fin end, and make the rapid dissipation of heat energy by heat loss through radiation with coordinating fan pressure driving air-flow.
as shown in Figure 1, analyse and observe the combination schematic diagram for the oil-containing bearing heat radiation fan of known technology, this radiation fan 1 mainly has a fan base 11, has a beam barrel 111 on this fan base 11, be provided with a bearing 12 in this beam barrel 111, on this fan base 11, group is provided with an impeller 13 again, these impeller 13 outer rings are provided with a plurality of blades 131, and be extended with an axle center 132 in the inboard, this axle center 132 is arranged in described bearing 12 and is detained knot and locate, 132, this bearing 12 and axle center are perfused with oil film 121 again, and the position measurement that its fan base 11 and bearing 12 and impeller 13 is mutual is adjusted to the optimum operation position, can be by oil film 121 stable rotation on bearing 12 with its axle center 132 when its radiation fan 1 operates, therefore, its axle center 132 is only supported by the support force of oil film 121 with respect to the running position of bearing 12, but the support force that its radiation fan 1 its oil film 121 produces is still the eccentric force that produces when turning round less than it, therefore 12, its axle center 132 and bearing still have the phenomenon of frictional impact and produce, again or after its radiation fan 1 is subjected to external force collision, the striking force of external force also can make its shaft core position skew, its axle center 132 is collided to bearing 12 and produce vibration, and its radiation fan 1 just can or collide the Noise and vibration that causes generation that running is arranged because of its position skew, and can increase simultaneously the abrasion condition of its axle center 132 and bearing 12 and affect working life of its radiation fan 1, though again or the support force of its oil film 121 can make its axle center 132 return back to the optimum operation position, but after being squeezed, its oil film 121 need take a long time reply, its axle center 132 returns back to the also increase relatively of time of optimum operation position relatively, and the time of noise producing also can extend relatively,
Therefore known technology has following shortcoming:
1. easily produce noise and vibration;
2. abrasion condition increases;
3. the time of noise producing is long;
4. affect working life.
Therefore, how to solve above-mentioned public problem and disappearance, the inventor who is this case desires most ardently to the relevant manufacturer that is engaged in the industry the direction place that research improves.
Summary of the invention
For this reason, for effectively solving the above problems, main purpose of the present invention reduces wear and reduces running noise and vibration and improve the oil bearing fan device in working life providing a kind of.
But another object of the present invention is at the oil bearing fan device that a kind of Quick-return fan running stability is provided.
In order to achieve the above object, the invention provides a kind of oil bearing fan device, this oil bearing fan device comprises a fan base, at least one oil-impregnated bearing, at least one magnetic element and an impeller, this fan base one side has a beam barrel, this beam barrel has a bearing hole, described oil-impregnated bearing is arranged in this bearing hole, and this oil-impregnated bearing has an axle center hole and at least one receiving hole, described magnetic element is arranged at the receiving hole position, and this impeller has a plurality of blades and an axle center, and this axle center is hubbed in this axle center hole; By this, described magnetic element can produce a magnetic adsorptive power and make the axle center Quick-return to the optimum operation position the axle center, reduces wear and reduces running noise and vibration to reach, and improving the effect in working life; Therefore the present invention has following advantages:
1. reduce the generation that produces noise and vibration;
2. the situation that reduces wear produces;
3. reduce the noise producing time;
4. improve working life.
