Abstract

The utility model provides an improved cooling fan structure which mainly comprises units of an outer frame, a stator, a plastic nano bearing, a rubber magnetic stripe ring, a magnet outer ring, fan blades and the like. Particularly, the outer frame is provided with an accommodating space and a closed surface, a hollow fixing column is arranged at the center of the closed surface, a magnet is arranged at one end of the fixing column for closing, a metal shaft core is arranged at the center of the fan blades which can be placed in the accommodating space of the outer frame, the shaft core is arranged in the plastic nano bearing in a penetrating mode, and the end edge of the shaft core keeps a certain distance from the magnet to be not in contact with the magnet. When the improved cooling fan structure revolves, a magnetic attraction force is produced by the magnet to the shaft core of the fan blades to maintain and fix the shaft core at the center position of the plastic nano bearing so that effects of reducing abnormal moving, abrasion and noises and increasing revolving service life are achieved.

Description

The cooling fan structure improvement

Technical field

This creation about a kind of improvement of radiation fan with progress greatly, espespecially a kind ofly reduce wear and reduce running noise and vibration, and improve the cooling fan structure improvement in working life.

Background technique

Electronic product development is constantly to promote usefulness fast, causes electronic components often to have high temperature to supervene in running, if can't solve, gently then causes usefulness to reduce, and is heavy then cause the damage of electronic product.Therefore, industry is without thinking little of this problem.

Be usually used in solving in the electronic product technological means of heat dissipation problem, radiating fin is set up in many employings or radiation fan is reached, and is wherein better with the radiation fan effect again.But radiation fan at present commercially available or commonly used is in using upper ubiquity to comprise: easily produce and rock and noise; Cause Fast Wearing because rocking; Running continues that noise producing is arranged; Because quick mill is led the direct scarce fraud such as working life that affects.

Probe into its reason nothing more than, though between the rotating shaft of fan and rotating shaft film lubrication is arranged, because of the gap slightly large, and the other end of rotating shaft is unfixing, a little off center position is arranged, in the course of time when causing turning round, naturally cause bearing or rotating shaft contact surface impaired, running noise is followed, moreover, because turning round more smoothly, fan usefulness is given a discount, relatively, also can increase electric power and expend, affect simultaneously the working life of this radiation fan.

Therefore, the usefulness that how to solve radiation fan commonly used reduces, and is the problem place that this case institute wish solves.

Summary of the invention

Mould between nano bearing processed and magnet and be provided with Lubricants.

More be provided with an annular ditch groove on the axle core, and be combined with a clasp.

The axle core with mould the nano bearing processed two ends that combine and be provided with O shape ring.

Thus, can produce a magnetic adsorptive power to the axle center by described magnetic element, make this axle center get Quick-return to the optimum operation position, reduce wear and reduce running noise and vibration to reach, and improve the effect in working life.

Characteristic on the above-mentioned purpose of this creation and structure thereof and the function will be explained according to appended graphic preferred embodiment.

Embodiment

See also shown in Figure 1ly, create the radiation fan exploded view of a preferred embodiment for exposure has this; Wherein the composition of this radiation fan 1 includes at least:

One housing 2 has the containing space 21 of a hollow, and is provided with a sealing surface, is provided with a hollow fixing column 22 in these sealing surface central authorities, and an end of this fixing column 22 is provided with a magnet 23 sealings;

One stator 3 is located in the containing space 21, includes a pcb board 31 with the electronic component combination, and this pcb board 31 is provided with a hollow jack-post 311, establishes most silicon steel plates 32 on every side and is arranged with coil 33, and this hollow jack-post 311 also is sheathed on the fixing column 22;

One moulds nano bearing 4 processed, is the bearing of being made through the nanometer processing procedure by plastic, is embedded in the fixing column 22, be different from general common metal bearing processed, and this to mould nano bearing processed 4 interior outsides smooth very thin, be enough to reduce the wearing and tearing of surface of contact;

One rubber magnetic stripe circle 5 is established the structure kenel of a plurality of magnetic stripes for the rubber ring inner face, and is sheathed on silicon steel plate 32 peripheries of stator 3;

One magnet outer shroud 6 is the annulus of a hollow tool magnetic, is sheathed on rubber magnetic stripe circle 5 peripheries;

One flabellum 7 is provided with a metal axle core 71 in central authorities, and this flabellum 7 can be put into the containing space 21 of housing 2, and this axle core 71 wears and mould nano bearing 4 processed, and the ora terminalis of this axle core 71 then keeps a distance not contact with magnet 23.

See also shown in Fig. 2,3, disclosing has this to create the radiation fan constitutional diagram of a preferred embodiment; According to above-mentioned each unit, in assembling, in order with stator 3, mould nano bearing 4 processed, rubber magnetic stripe circle 5, magnet outer shroud 6 and flabellum 7 and insert in the containing space 21 of housing 2, and make the axle core, mould nano bearing 4 processed, fixing column 22 and hollow jack-post 311 be the coaxial combination pattern, so just can organize to consist of a complete radiation fan; Simultaneously, as shown in Figure 3, in moulding nano bearing 4 processed and 23 clip spaces of magnet, be provided with lubricant oil 8 lubrication is provided, and be provided with annular ditch groove 72 and be provided with again clasp 73 in axle core 71, and wear in conjunction with moulding nano bearing processed 4 rear two ends in this axle core 71 and to be arranged with again O shape and to encircle 74, to avoid the seepage of lubricant oil 8.

Please continuing, it is shown in Figure 3 to consult again, and disclosing has this to create the radiation fan assembled sectional view of a preferred embodiment; This radiation fan 1 in the use, when fan 7 running, its axle core 71 rotates in moulding nano bearing 4 processed rapidly, because the magnet 23 of metal axle core 71 and fixing column 22 1 ends is corresponding but do not contact, therefore this magnet 23 can produce a magnetic attraction to axle core 71, and do not affect its smooth rotation, in order to do making this axle core 71 can remain on optimal running central position, promote on the one hand the stability of these fan 7 runnings, axle core 71 is reduced and the contact wear of moulding nano bearing 4 processed, natural energy reaches and reduces the noise and vibration situation, further reaches the effect that increases the service life; Simultaneously, in the lubricant oil 8 of moulding 23 of nano bearing 4 processed and magnet, except provide axle core 71 reduce friction with the effect that reduces noise, more can be with cooling effect; Thus, not only in the running of fan 7, can get rid of the power consume, reach complete smooth and easy power output, also can under the use same power, obtain the output of optimum operation usefulness and can save electric power.

Above is illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it in spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
