Abstract
The utility model relates to a low-noise radiating fan comprising a motor stator base; the internal chamber of the base is sheathed with a fan blade rotating shaft; the outside of the base is provided with a motor stator group which consists of an upper coil frame, a lower coil frame and a silicon steel sheet fixedly clamped between the upper coil frame and the lower coil frame; the fan blade rotating shaft is made of magnetic material; and correspondingly, the motor stator base is internally provided with a magnet which is used for adsorbing the fan blade rotating shaft. The low-noise radiating fan has the benefits that the magnet is arranged in the motor stator base, therefore, during the assembly process of the product, the fan blade rotating shaft can be effectively sucked and positioned, the magnetic field center of the two rotors and the stator of the motor stator base and the fan blade rotating shaft can be always kept on the same plane; and the electromagnetic noise generated when the radiating fan runs owing to the staggered position resulting from different installation positions can be eliminated. Furthermore, the shaft sleeve of the motor stator base and the connecting position of the shaft sleeve and the fan blade are provided with a sealing bulge, thus further reinforcing the sealing performance after the product is assembled and effectively prolonging the service life of the product.
Description
[technical field]
The utility model relates to a kind of radiation fan, refers in particular to a kind of low-noise heat radiation fan that information communication product such as computer main can effectively reduce the operation noise that is used for.
[background technique]
Along with constantly popularizing of electronics applications, the product heat dissipation technology of its pairing is also increasingly mature, and it is the most basic in the heat dissipation technology with radiation fan, and no matter existing radiation fan contains bearing type or roller bearing type, it is quite ripe that its structural manufacturing process has developed, can satisfy mass-produced demand.Yet, demand increase along with radiation fan, existing radiation fan is because its reasons in structure, in the practical set process, often be difficult to guarantee assembly relation good between fan motor stator base and flabellum, the central point that causes assembling the rotor of back radiation fan and stator makes product can produce bigger self-vibration when reality is used and produces electromagnetic noise greatly not on same plane.In addition, existing radiation fan lacks necessary sealing at motor stator pedestal and flabellum shaft connection place, this often causes the contamination by dust that is subjected to of motor stator base interior easily, even influence is provided with the content of oil-impregnated bearing in it, and finally make excessive wear between bearing and flabellum rotating shaft and damage that working life is all shorter.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, a kind of good airproof performance is provided and can effectively guarantees the low-noise heat radiation fan of assembly relation good between motor stator pedestal and flabellum.
The purpose of this utility model is achieved in that a kind of low-noise heat radiation fan, it comprises a motor stator pedestal, the pedestal inner chamber is socketed with the flabellum rotating shaft, pedestal is provided with the motor stator group outward, the motor stator group is made up of upper and lower coil carrier and clamping silicon steel sheet therebetween, its improvements are: described flabellum rotating shaft is made by magnetic material, corresponding, in the motor stator pedestal, be provided with the magnet that is used to adsorb the flabellum rotating shaft;
The last coil carrier of described motor stator group is extended with the convex edge in flabellum rotating shaft side direction, extend upward in the convex edge upper surface to be formed with the airtight projection of a circle first fastening; The bottom surface has extended to form a circle second downwards and has fastened airtight projection around the flabellum rotating shaft root;
The diameter of the described first airtight projection is slightly less than the diameter of the airtight projection of second fastening;
The slightly larger in diameter of the described first airtight projection is in the diameter of the airtight projection of second fastening;
Described magnet is arranged in the motor stator pedestal under the flabellum rotating shaft.
Than common radiation fan, the beneficial effects of the utility model are by a magnet is installed in the motor stator pedestal, thereby effectively rotating shaft attracts the location to flabellum when product assembles, thereby the magnetic field center that has guaranteed flabellum rotating shaft and motor stator pedestal two rotors and stator remains on the same plane, thereby thereby has eliminated both electromagnetic noises when radiation fan running that dislocation produces takes place because of the mounting point is different.In addition, on the axle sleeve of motor stator pedestal and with the flabellum connecting part, be provided with seal convexity, further strengthened the sealing after product assembles, the working life that has effectively strengthened product.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is an overall structure explosive view of the present utility model
[embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As shown in Figure 1, the utility model relates to a kind of low-noise heat radiation fan, it comprises motor stator pedestal 1, motor stator group 2, flabellum 3, wherein motor stator pedestal 1 center is provided with an axle sleeve, bore sleeve then with bearing 4 sockets, the rotating shaft 301 at flabellum 3 centers is set in the bearing 4, also is provided with jump ring 5 and Graphite pad 6 in the axle sleeve bottom.The axle sleeve outer side surface of pedestal 1 is provided with motor stator group 2, motor stator group 2 is by last coil carrier 201, lower coil frame 203 and clamping silicon steel sheet 202 is therebetween formed, wherein go up coil carrier 201 and in flabellum 3 rotating shafts 301 1 side direction, be extended with convex edge 204, convex edge 204 upper surfaces extend upward and are formed with a circle first fastening airtight protruding 205, corresponding, the bottom surface has extended to form a circle second downwards and has fastened airtight protruding 302 around flabellum 3 rotating shafts 301 roots, for guaranteeing the effective isolation obturation effect, described first airtight protruding 205 the diameter is answered smaller or is fastened airtight protruding 302 diameter greater than second.
3 rotating shafts 302 of described flabellum are made by magnetic material, corresponding, in motor stator pedestal 1, be provided with the magnet 101 that is used to adsorb flabellum 3 rotating shafts 302, this magnet 101 is arranged in the motor stator pedestal 1 under flabellum 3 rotating shafts 302, can be when flabellum 3 assembles with pedestal 1 by this magnet 101, its rotating shaft 302 is held, cooperate the magnetic field center of realizing fan 3 rotor magnets 302 and motor stator group 2 silicon steel sheets 202 to remain on the same plane, and in motor stator pedestal 1 under the effect of magnet 101, the mounting point that can guarantee radiation fan does not change with the present position is different, thereby reduces the electromagnetic noise that fan is produced in the running effectively.
In sum as seen, the utility model is by installing a magnet in motor stator pedestal 1, thereby effectively 3 rotating shafts 302 attract the location to flabellum when product assembles, thereby guaranteed that flabellum 3 rotating shafts 302 and the magnetic field center of motor stator pedestal 1 liang of rotor and stator remain on the same plane, thereby thereby eliminated both electromagnetic noises when radiation fan that dislocation produces taking place because of the mounting point is different turning round.In addition, on the axle sleeve of motor stator pedestal 1 and with flabellum 3 connecting parts, be provided with seal convexity, further strengthened the sealing after product assembles, the working life that has effectively strengthened product.
It is to be noted; the utility model is not limited to above-mentioned mode of execution; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection domain of the present utility model.
