Description
Technical field
The present invention relates to fan wheel structure and manufacture method thereof, especially be particularly related to a kind of fan wheel structure integral body that promotes and on making, reach better uniformity and saving cost of production and the fan wheel structure of reducing work hours and manufacture method thereof.
Background technique
In recent years along with the development of electronic industry, the performance of electrical assembly promotes rapidly, calculation process speed is more and more faster, and the arithmetic speed of its inside chip group constantly promotes, number of chips also constantly increases, and the also corresponding increase of heat that described chip distributes when work, if these thermals source are not in time distributed, the performance of electrical assembly will greatly be affected, make the calculation process Speed Reduction of electrical assembly, and along with the continuous accumulation of heat, also may burn electrical assembly, therefore heat radiation has become one of important topic of electrical assembly, is common method and utilize radiation fan as sink.
The radiation fan of generally seeing then is divided into the fan that plastic material and metal material are made, and the durability of plastic fan integral body relatively is not so good as the durability of metal fan integral body in actual use, for example the blade of plastic fan is clashed into easily or pushes and damage, so that make the design that the producer of fan begins to research and develop the metal fan one after another.
See also shown in Figure 1ly, Fig. 1 is the schematic perspective view of prior art fan wheel structure; This fan wheel structure is to be made of a metallic material, and it comprises a wheel hub 10 and plural blade 12 consists of, wherein aforementioned respectively these blade 12 welding are located on the periphery outside of this wheel hub 10, and aforementioned welding manner is in order to a side of each blade 12 relative wheel hub 10 is close to the outer rear flank of relative wheel hub 10 peripheries, and adopt in the aforementioned position that both are close to the place spot welding mode respectively these blade 12 solid weldings on this wheel hub 10, and then form described fan wheel structure.
Yet, though aforementioned fan wheel structure also can improve the not good and easy impaired problem of the anti-degree of plastic fan, but but extend another problem, namely when making this impeller, sequentially respectively each blade 12 is being welded on this wheel hub 10, so that it is consistent to be adjusted at position and the even angle of each blade 12 on this wheel hub 10, just can make aforementioned fan wheel structure when rotated, the air flow energy that this blade 12 respectively is guided out evenly distributes, but because the relation of spot welding can cause error on each blade 12 position and the angle, cause easily the air turbulence of respectively these blade 12 guiding or produce the windage effect, and then make the not first-class phenomenon of uniformity of the blade of the impeller that produces.
And, can't keep necessarily because of the melting temperature of welding sometimes, often the excess Temperature because of spot welding causes burning wheel hub 10 or blade 12, or the excessively low phenomenon of dry joint (or cold welding) that causes of the temperature of spot welding produces, therefore, the impeller quality that produces on the one hand differ and speed of production slow; Then can cause on the other hand working life limited, cost of production is high and increase the problem in man-hour.
The above, have following shortcoming in the existing fan wheel structure:
1. cost of production is high.
2. increase man-hour.
3. speed of production is slow.
4. uniformity is not good.
5. quality differs.
