Described fin is thin slice the linking to each other in twos and folding anyway pliciform fin through punching press formation with high thermal conducting material.
Described containing cavity connects the position and surrounds with the interior position that is connected outside bending.
The described cup of going up is with high thermal conducting material drawing.
Described following glass with high thermal conducting material drawing.
The described cup of going up is close to the containing cavity inwall with following glass outer wall.
The described cup content that goes up comprises LED substrate, chip and lens.
A described following glass content comprises driver.
A described following glass attachment comprises lamp holder.
The beneficial effect of the finned LED heat abstractor of folding fan of the present invention is: be convenient to produce in enormous quantities, with low cost, area of dissipation is big, radiating efficiency is high, cost performance is high.

The specific embodiment
Like 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, go up cup 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; The upper/lower terminal of this containing cavity 15 is respectively equipped with holddown groove 11 and following holddown groove 12, cup 2 and following glass 3 upper/lower terminal that is placed in containing cavity 15 respectively this on, on this glasss 2 and following glass 3 oral area be 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, and cup 2 is respectively equipped with riveted holes 22 and following riveted holes 32 with following glass 3 bottom on this, on this glasss 2 and following glass 3 be integral through last riveted holes 22 and following riveted holes 32 riveteds.This fin 1 is thin slice the linking to each other in twos and folding anyway pliciform fin through punching press formation with high thermal conducting 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, like Fig. 7 and shown in Figure 8.Again the pliciform fin is surrounded containing cavity 15, like Fig. 5 and shown in 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 through last riveted holes 22 and following riveted holes 32 and be integral with following glass of 3 riveteds, and is as depicted in figs. 1 and 2.Whole process is very easy and easy to operate, has significantly reduced manual work 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 enforcement explanation 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, characteristic, all should belong to of the present invention founding within purpose and the claim.
