The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 or shown in Figure 8, the technical scheme of the finned LED heat abstractor of folding fan of the present invention is: comprise fin 1, last glass 2 and following glass 3, this fin 1 forms through punching press earlier and links to each other in twos and folding anyway pliciform fin, surround the finned containing cavity 15 of a folding fan again, on this containing cavity 15, following two ends are respectively equipped with holddown groove 11 and following holddown groove 12, should go up cup 2 and following glass 3 be placed in respectively containing cavity 15 on, following two ends, the oral area that should go up cup 2 and following glass 3 is respectively equipped with glass a claw type crimping 21 and a following glass of claw type crimping 31, should go up cup claw type crimping 21 and catch on holddown groove 11, this following glass of claw type crimping 31 catches on down holddown groove 12, the bottom that should go up cup 2 and following glass 3 is respectively equipped with riveted holes 22 and following riveted holes 32, and glasss 2 are integral with following riveted holes 32 riveteds by last riveted holes 22 with following glass 3 on this.This fin 1 is thin slice the linking to each other in twos and folding anyway pliciform fin through punching press formation with metal, composite, the contour thermal conducting material of nano material.This containing cavity 15 connects position 13 and surrounds with the interior position 14 that is connected outside bending.Should go up the high thermal conducting material drawing of cup 2 usefulness.This following glass of high thermal conducting material drawing of 3 usefulness.Should go up cup 2 and be close to containing cavity 15 inwalls with following glass 3 outer wall.Cup 2 content be should go up and LED substrate, chip and lens comprised.These following glass of 3 content comprises driver.These following glass of 3 attachment comprises lamp holder.
In this specific embodiment, elder generation becomes the fin band and the while that link to each other in twos to become pliciform with the interior position 14 place's pressing and bending that are connected in connection position 13 outside fin 1 stamping-out of the finned LED heat abstractor of folding fan of the present invention, as shown in Figure 7 and Figure 8.Again the pliciform fin is surrounded containing cavity 15, as shown in Figure 5 and Figure 6.To go up cup 2 and following glass 3 upper/lower terminal that is placed in containing cavity 15 respectively at last, make cup claw type crimping 21 catch on holddown groove 11, following cup claw type crimping 31 catches on down holddown groove 12, will go up cup 2 by last riveted holes 22 and following riveted holes 32 and be integral with following glass of 3 riveteds, as depicted in figs. 1 and 2.Whole process is very easy and easy to operate, has significantly reduced artificial and material cost, because the finned LED heat abstractor of folding fan of the present invention manufacture process is punching operation entirely, simple, volume production efficient height has significantly reduced cost of labor; The plication fin can be cooked very thinly and quantity fin can be rolled over a lot, and like this, the material that consumes seldom just can obtain very big area of dissipation; The finned LED heat abstractor of folding fan is an integral body that forms via punching press, bending, riveted and do not have hot road breakpoint.Therefore, the finned LED heat abstractor of folding fan can be accomplished: with low cost, cost performance is high, radiating efficiency is high.
Shown in the implementation and accompanying drawing that the present invention is above, being one of preferred embodiment of the present invention, is not to limit to the present invention with this, be with, such as with approximate, identical person such as structure of the present invention, device, feature, all should belong to of the present invention founding within purpose and the claim.
