Background technique
Heat dissipation problem is one of maximum technical bottleneck of light and thin type electronics and IT products (as notebook computer, panel computer etc.) always, heat radiation quality is related to degree of stability and complete machine working life of product operation, so heat dissipation problem is the important step in its product specification.
Notebook computer for example, because its volume is smaller, heater element is concentrated, and heat dissipation design has sizable difficulty, and while normally using, the surface temperature of common CP U is more than 50 degrees Celsius, and and Baidu is even gone up up to 80 degree especially in inside.What the fan-cooled radiator adopting at present was generally used is plastic cement electric fan, and it mainly contains following two large defects in heat radiation working procedure:
The first, itself can not dispel the heat the flabellum of plastic cement material, accelerate the means of heat radiation and can only accelerate circulation of air by improving its rotating speed, but this consequence is to cause noise and reduced fan life in the confined space;
Second, the flabellum of plastic cement material is worked and can be caused electric fan temperature distortion for a long time between 50 ℃-100 ℃, cause its dynamic balancing to be lost efficacy, produce noise and accelerate bearing wear, radiating effect is declined, so that affect performance and the life-span of product, in serious situation, can cause the high temperature abnormality of operation element and burn.
Why adopting the flabellum of plastic cement material, is because also do not have the global formation flabellum of metal material to substitute at present.The fan inside flabellum of a small amount of location high-end product adopts metal material manufacture, because the manufacture method that adopts a plurality of single leaf blades to be welded to connect forms, although radiating effect be improved, but in enormous quantities, produce and have difficulties fast, cost of production is very high.
At present, electronic product is day by day frivolous, and radiation system is had higher requirement, and the manufacture model utility of the whole flabellum of metal fan has required to provide the fastest possibility that realizes to meeting product specification.
Metal powder injection molding is the new forming technique developing rapidly in the world in recent years, it is advantageous that the micro metal component that can form complicated shape, and each position even density of goods, excellent performance.
The technological process of metal powder injection molding is for to be uniformly mixed into fine metallic dust and organic binder for having the material of rheological characteristic, the die cavity that adopts advanced injector injection to have part shape forms blank, subsequently by removing Bond and through sintering, making its high compaction become fabricated metals.
My company passes through the structural feature of research electric fan, and the technique basis in conjunction with metal powder injection molding, has adopted unique binder formula and degreasing sintered technique, and model utility has produced the whole flabellum of metal fan.
Model utility content

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of metallic dust shot moulding fan is provided, comprise: wheel hub, be that radial ring is located at a plurality of fan blade on wheel hub and for connecting the wheel disc of fan blade, described fan blade extends to wheel disc from the edge section of wheel hub, and described a plurality of fan blade are integrated type and connect and be shaped to one with wheel hub and wheel disc.
In preferred embodiment of the utility model, the blade quantity that described fan blade is disperseed in circumference of hub is 15 ~ 40.
In preferred embodiment of the utility model, described fan blade is formed between wheel hub and wheel disc in the mode of leaning forward.
In preferred embodiment of the utility model, described fan blade is formed between wheel hub and wheel disc in hypsokinesis mode.
In preferred embodiment of the utility model, described fan blade is 15 ~ 30 degree with respect to the angle of inclination of wheel hub.
In preferred embodiment of the utility model, the external diameter size of described fan blade is 20 ~ 50mm, and the thickness of described single fan blade is more than or equal to 0.1 ~ 0.2mm.
In preferred embodiment of the utility model, the fan blade quality of described integral body is 1 ~ 5g.
The beneficial effects of the utility model are: the utility model can form integrated metal fan, and each position even density of metal fan, dynamic balance performance is good, extended fan life, resistance to high temperature is better, radiating effect improves greatly, and cost of production is compared and reduced more than 80% with the fan of metal solder.
