Description

Oil bearing fan structure

Technical field

The invention provides a kind of oil bearing fan structure, espespecially one can reduce wear and reduce running noise and vibration, and improves the oil bearing fan structure 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 is arrange 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 the three-dimensional assembled sectional view of the oil-containing bearing heat radiation fan of known technology, 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 position, axle center 132 offset, even make its axle center 132 collide and produce vibration to bearing 12, cause this radiation fan 1 just because of the skew of its position or collide and produce the facts such as the noise of the Noise and vibration of running, and also can increase its axle center 132 and the abrasion condition of bearing 12 simultaneously, affect the working life of this 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 and abrasion produce 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 creator 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 is providing one to reduce wear and is reducing running noise and vibration, and improves the oil bearing fan structure in working life.

Another object of the present invention provide a kind of can the oil bearing fan structure of Quick-return fan running stability.

In order to achieve the above object, the invention provides a kind of oil bearing fan structure, comprise a fan base, an oil-impregnated bearing and an impeller, this fan base side has a beam barrel, this beam barrel has a bearing hole and bag is provided with at least one magnetic element, and described oil-impregnated bearing is arranged in bearing hole, and this oil-impregnated bearing has an axle center hole, described impeller has multiple blade and an axle center, and this axle center is hubbed in this axle center hole; By this, a magnetic adsorptive power can be produced to axle center by described magnetic element, make this axle center obtain Quick-return to optimum operation position, reduce wear to reach and reduce running noise and vibration, and improving 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.
