Description
Technical field
The utility model is a kind of equilibrium structure of annular axial flow fan, but the degree of balance that relates in particular to a kind of both rapid adjustment annular axial flow fan is to keep equilbrium running, the equilibrium structure that can save the annular axial flow fan of material and construction cost again simultaneously.
Background technique
Electronics and IT products (for example: popularize day by day and use more extensive by use computer etc.), so demand increases, then it is rapid to drive the electronics and information industry technical development, the trend development that impels electronic information technology to carry out arithmetic speed towards promoting, increase access capability, the phenomenon that causes the spare part in the aforementioned electronic information products to have temperature to raise often with running at working at high speed, and the spare part in the general electronics and IT products is to be provided with radiator and radiation fan in its position in order to the method that solves heat radiation.
General annular axial flow fan structure is at some flabellums of the outside formation of the wheel hub of annular axial flow fan, one side of described flabellum outer end is extended a ring body, and should the annular axial flow fan in penetrating molded working process, injected plastics material often easily inhomogeneous when penetrating cause whole wheel hub, the weight inequality of flabellum or ring body, thereby influenced the balance that annular axial flow fan rotates, if described wheel hub, the weight inequality that flabellum or ring body are mutual, the annular axial flow fan will run-off the straight when rotating situation, cause increasing between its central shaft and the axle sleeve friction with rock, aforementioned friction not only makes annular axial flow fan produce noise with the phenomenon of rocking, and can cause the axle center accelerated ageing of annular axial flow fan and shortened working life of annular axial flow fan, more will reduce the total quality of the product mix of using this annular axial flow fan, and also can cause phenomenons such as heat dissipation is not obvious.
There is manufacturer to adopt described wheel hub to be carried out regional counterweight to adjust the uneven situation of described annular axial flow fan weight now, as shown in fig. 1, it is the stereogram of the annular axial flow fan equilibrium structure of prior art, described annular axial flow fan 70 mainly has a wheel hub 71 and a ring body 72,72 of described wheel hub 71 and described ring bodies have a slice flabellum 73 at least, and described wheel hub 71 has different wheelbases with ring body 72 respectively with respect to annular axial flow fan 70 centers, and the uneven or situation that tilts of weight when taking place in described annular axial flow fan 70 in the running, be on described wheel hub 71, directly to carry out counterweight, a plurality of grooves 711 will be formed with on the described wheel hub 71, object can be set in groove 711 be used for carrying out counterweight, but because of described wheel hub 71 and ring body 72 with in have relative gap in the heart, so carrying out the required weight of counterweight on described wheel hub 71 need be greater than several times of ring body 72, just can reach the purpose of balance, therefore it is higher to carry out the spent object cost of counterweight on wheel hub 71, in addition, after the counterweight of carrying out with flabellum via wheel hub 71, when described annular axial flow fan 70 turns round, same easily because the weight of ring body 72 unequal with wheelbase on the situation of influence run-off the straight when causing annular axial flow fan 70 to rotate, cause increasing central shaft and the friction between the axle sleeve and the shaking phenomenon of annular axial flow fan 70, therefore, need expend the engineering time and adjust weight.In sum, prior art has following shortcoming:
1. on wheel hub, carry out counterweight and need expend the purpose that more material just can reach balance;
2. the balance that is reached when carrying out counterweight on wheel hub is affected because of the wheelbase of ring body and the inequality of weight easily in the running;
3. consume material cost and construction cost.
Therefore, how to solve problem and disappearance that above-mentioned existing electronics and IT products exist, be the direction that inventor of the present utility model does one's utmost to study improvement.
The model utility content
For effectively addressing the above problem, main purpose of the present utility model is to provide a kind of blade profile of flabellum of both can effectively having avoided destroyed by operation, can reach and keep the annular axial flow fan equilibrium structure of balance of fan running simultaneously fast again.
For achieving the above object, the utility model provides the equilibrium structure of a kind of annular axial flow fan, mainly comprise: a wheel hub and a ring body, described ring body is around the outside that is arranged at wheel hub, and between described wheel hub and described ring body, be formed with a ring runner, be provided with the multi-disc flabellum in the described ring runner, every flabellum all has a inner and an outer end, described the inner and outer end are connected to the outside of described wheel hub and the inboard of described ring body, and have a plurality of grooves on the described ring body, each groove around the described ring body around setting, and each groove part has a holding space, corresponding at least one counterbalance, described counterbalance loading and unloading are all in described holding space, so that adjust the weight balancing of full annular axial flow fan.
