Abstract

The utility model discloses a new type radiator of a fan, comprising a fan-blade body case, a stator, and a fan seat. Wherein, the hole inner margin at the proper site of the silicon steel plate group of the stator is provided with a semi-round hole. The hole at the proper site of an upper insulated seat is designed to protrude upwards, the protruding inner margin is provided with a convex tenon, and the tenon and a ring groove arranged at the proper site of the outer margin of the top of a shaft sleeve. The periphery of the inner circular hole of a lower insulated seat is extended with a plurality of segments of cantilevers, and the tail end of each cantilever forms transversely an outer circular arc segment which corresponds to the silicon steel plate group and the upper insulated seat. The periphery of the surface of the insulated seats is provided with corresponding pulling sheets. In the shaft sleeve, sleeves and O-shaped rings are sequentially arranged from a moistening bearing to a retaining ring. The badness generated by the ball bearing in the shaft sleeve is reduced, thus reducing the generation of noises, and the assembly or the dismounting becomes much easier.

Description

Novel fan radiator

Technical field

The utility model relates to the heat dissipation technology field, specifically, relates to a kind of novel fan radiator that adopts fan to carry out forced heat radiation.

Background technique

At present, existing fan radiator, by a flabellum housing, stator and fan base are formed, wherein this flabellum housing inner edge is provided with magnet, and be provided with axle, the coil of coiling silicon steel sheet group is established in the centre between the upper and lower excitatory yoke sheet of stator, and wear on the circuit board that is positioned therebetween in the fan base with an axle sleeve, and plug the base plate that is consolidated in the fan base, last again the axle of flabellum housing is worn ball bearing and the self-lubricating bearing that is articulated in the axle sleeve, be held on the axle end with clasp again, the formation of silicon steel sheet group and axle sleeve is closely cooperated.

Though above-mentioned existing fan radiator can reach the practical effect of heat radiation, yet silicon steel sheet group and axle sleeve form and closely cooperate, easy crowded because of the silicon steel sheet group, make axle sleeve also produce internal stress toward the center of circle, and then the ball bearing in the axle sleeve is extruded, when fan operated, the axle of flabellum housing was rotated, and easily is that ball bearing makes a noise; Moreover, the axle of flabellum housing penetrates in the axle sleeve, easily too big because of crack between clasp and the self-lubricating bearing, move and present down, cause unsettled rotation, and produce bigger noise, or because of crack between clasp and the self-lubricating bearing too little, and be urgent state, cause surface friction drag, and consume rotating power and power; Upper and lower excitatory yoke sheet and silicon steel sheet group are worn when being fixed in axle sleeve, and the processing of complexity causes mounting or dismounting to be difficult for, and will certainly destroy the wherein element of stator.

Technology contents

Goal of the invention of the present utility model is intended to overcome above-mentioned prior art deficiency, and a kind of novel fan radiator is provided, the favorable working performance of this novel fan radiator, and noise is low, and assembly and disassembly are easy.

Goal of the invention of the present utility model is achieved in that novel fan radiator is by the flabellum housing, stator and fan base are formed, wherein on the silicon steel sheet group of this stator, have, following insulation base, the silicon steel sheet group is placed, between the following insulation base and be arranged in an axle sleeve, this axle sleeve wears and is positioned in the circuit board and base plate set in the fan base, set axle correspondence penetrates in the ball bearing and self-lubricating bearing set in the axle sleeve in the flabellum housing, be held on the axle end with clasp again, the hole inner edge at the moderate place of described silicon steel sheet group is provided with semicircle orifice, and the hole of going up the moderate place of insulation base is made as upwards projection, its projection inner edge is provided with tenon, be provided with ring groove shape with axle sleeve top outer rim appropriate location and become corresponding buckle, and circular hole hole periphery extends outward several sections cantilevers in this time insulation base, each cantilevered distal end laterally forms cylindrical segmental arc and aforementioned silicon steel sheet group, and last insulation base forms correspondence.

The described insulation base surface periphery that goes up is provided with the relative sheet of pulling;

Be provided with annulus in regular turn between self-lubricating bearing and the clasp in the described axle sleeve.

Technique effect of the present utility model is: by the semicircle orifice design of silicon steel sheet group, and the corresponding buckle of annular groove of the tenon of last insulation base and axle sleeve top outer rim appropriate location, silicon steel sheet group and axle sleeve top can not formed to closely cooperate, when making the running of fan group, it is bad to reduce the interior ball bearing generation of axle sleeve, to reduce the generation of noise; By sleeve and o ring are set between self-lubricating bearing in the axle sleeve and the clasp in regular turn, in order to the stationary spindle position, when rotating to reduce axle, the bad result that produces; By the annular groove design of the tenon of last insulation base and axle sleeve, become when fan is assembled into easily, and by last insulation base relative pull the sheet design,, also become when making dismounting easily.

Embodiment

Embodiment 1:

As Fig. 1,2, shown in 3, the utility model is by flabellum housing 1, stator 2 and fan base 6 are formed, wherein these flabellum housing 4 inner edges are provided with magnet 41, and be provided with axle 42 in moderate place, and the silicon steel sheet group 52 of stator 5 is reeled for coil 55, on it, have, following

insulation base

52,53,51 central authorities place with the silicon steel sheet group, following insulation base 52, between 53, be arranged in an axle sleeve 54, this axle sleeve 54 wears and is positioned in the circuit board 61 and base plate 62 set in the fan base 6 set axle 42 in the flabellum housing 4, correspondence penetrates in ball bearing set in the axle sleeve 54 541 and the self-lubricating bearing 542, is held on axle 42 ends with clasp 543 again; Hole 511 inner edges at these silicon steel sheet group 51 moderate places are provided with relative semicircle orifice 512, and axle sleeve 54 sides are to convexing with tenon 547 for assist location by semicircle orifice 512.The hole 521 at last insulation base 52 moderate places is made as upwards bead, its bead inner edge is provided with tenon 522, can be provided with annular groove 544 with axle sleeve 54 top outer rim appropriate locations and form corresponding buckle, and be provided with the relative sheet 523 of pulling in last insulation base 52 surface periphery, and circular hole hole 531 peripheries extend outward several sections cantilevers in this time insulation base 53, each cantilevered distal end laterally forms cylindrical segmental arc and aforementioned silicon steel sheet group 51, and last insulation base 52 forms corresponding.This silicon steel sheet group 51 is provided with post hole 513,532 with following insulation base 53 peripheral segmental arcs, for wearing the some socles 63 to establishing on location and the circuit board 61.
