Description
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 use of electronics information product (such as: computer etc.) is increasingly universal and application is more extensive, because demand drives the technical development of electronics IT industry rapid, impelling electronics information towards performing the trend development that arithmetic speed promotes, access capability increases, causing the spare part in aforementioned electronic information product often to have high temperature to supervene in working at high speed.
For host computer, the heat that its internal central processing unit (CPU) produces accounts for major part, in addition, central processing unit when heat gradually rising can cause perform usefulness reduce, and when accumulation of heat is higher than its allowable limit, computer will be forced to work as machine, and severe patient more may cause damage phenomenon; Further, for solving the problem of electromagenetic wave radiation, usually carry out this host computer closed with 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 is taked in order to the mode solving heat radiation arranges radiator and radiation fan above it, some fins have been set up in the side of radiator, directly contact premise central processing unit with the surface of the opposite side of described radiator (not there is fin) and above-mentioned fin end can be conducted to make heat energy, and by heat loss through radiation with coordinate fan to force to drive air-flow to make the rapid dissipation of heat energy.
As shown in Figure 1, for known technology oil-containing bearing heat radiation fan analyse and observe combination schematic diagram, this radiation fan 1 mainly has a fan base 11, this fan base 11 has a beam barrel 111, a bearing 12 is provided with in this beam barrel 111, on this fan base 11, group is provided with an impeller 13 again, this impeller 13 outer ring is provided with multiple blade 131, and an axle center 132 is extended with in inner side, this axle center 132 is arranged in described bearing 12 and is detained knot location, oil film 121 is perfused with again between this bearing 12 and axle center 132, and position measurement mutual with bearing 12 and impeller 13 for its fan base 11 is adjusted to optimum operation position, can 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 supports by means of only the support force of oil film 121 relative to the running position of bearing 12, but the support force that its oil film 121 of its radiation fan 1 produces is still the eccentric force produced when being less than its running, therefore the phenomenon still having frictional impact between its axle center 132 and bearing 12 produces, again or when its radiation fan 1 is by external force collision rift, the striking force of external force also can make its shaft core position offset, even make its axle center 132 collide and produce vibration to bearing 12, and its radiation fan 1 just can cause because of the skew of its position or collision the Noise and vibration producing and have running, and the abrasion condition of its axle center 132 and bearing 12 can be increased simultaneously and affect working life of its radiation fan 1, again or the support force of its oil film 121 though its axle center 132 can be made to return back to optimum operation position, but need to take a long time reply after its oil film 121 is squeezed, the time that its axle center 132 returns back to optimum operation position relatively also increases relatively, and the time that noise produces also can extend relatively,
Therefore known technology has its own shortcomings:
1. easily produce noise and vibration;
2. abrasion condition increases;
3. the time of noise generation is long;
4. affect working life.
Therefore, how to solve above-mentioned public problem and disappearance, the inventor being this case and the relevant manufactures of being engaged in the industry desire most ardently the place, direction studied and improve.
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.
Another object of the present invention provide a kind of can the oil bearing fan device of Quick-return fan running stability.
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 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 receiving hole position, and this impeller has multiple blade and an axle center, this axle center is hubbed in this axle center hole; By this, described magnetic element can produce a magnetic adsorptive power to axle center and make axle center Quick-return to optimum operation position, reduces wear to reach and reduces running noise and vibration, and improves the effect in working life; Therefore the present invention has following advantages:
1. reduce the generation producing noise and vibration;
2. the situation that reduces wear produces;
3. reduce noise generation time;
4. improve working life.
