Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
As shown in Figure 1, electronic instrument of the present invention is sides that touch electronic instrument with radiator structure 11, the heat release that above-mentioned electronic instrument is produced arrives the outside, specifically comprises a plurality of units radiating part 18 and a plurality of folding parts 19, and folding part 19 is connected between two adjacent unit radiating parts 18.
Folding part 19 connects above-mentioned unit radiating part 18.The folding direction of folding part 19 is to make above-mentioned unit radiating part 18 face-to-face.18 of unit radiating parts in these folding parts 19 form the zigzag of inclination, and the global shape of radiator structure 11 is exactly the form of folding fan (folding fan), as shown in Figure 3.Here, the interval between the unit radiating part 18 can be adjusted according to the ratio of folding part 19.For example as shown in Figure 2, the length of folding part 19 can increase the interval between the unit radiating part 18 during greater than the length of folding part 19 shown in Figure 1.
In addition, above-mentioned unit radiating part 18 and folding part 19 are to be made of same sheet metal, and the material of above-mentioned sheet metal can adopt copper, aluminium of heat dispersion excellence etc.And copper that the color of above-mentioned unit radiating part 18 and folding part 19 is not necessarily pure or aluminium color also can be described as other colors.Above-mentioned unit radiating part 18 and folding part 19 can show various texture and color through chromium plating or Nickel Plating Treatment.
As shown in Figure 3, the radiator structure 11 of said structure, is compared with the traditional heat-dissipating structure of using aluminum casting to form with the contact-making surface expansion of air because the unit radiating part 18 that distributes in its unit volume is very dense, and its heat dispersion can improve about 20～30%.
And above-mentioned radiator structure 11 can be applied to the pyrotoxin of various sizes.Because above-mentioned radiator structure 11 is sheet metals of fan-folded shape, can arbitrarily change shape, so be easy to touch the pyrotoxin of different shape.Meanwhile, above-mentioned radiator structure 11 is to be made of sheet metal, so need not to be equipped with special cutting tool, also can use by the Len req cutting.
The detailed structure of the unit's of introduction radiating part 18 below.
Above-mentioned unit radiating part 18 can comprise, the first radiating part 18a, the second radiating part 18b, connecting portion 18c and be positioned at the depressed part of connecting portion 18c below.
