Abstract

The utility model discloses a heat radiating sheet, which is composed of a set of fin sheets, wherein, both opposite side edges of each fin sheet are provided with transversal folding sides which have same orientation, and the folding sides are provided with permeable parts; the other sides of the fin sheets corresponding to the permeable parts of the folding sides are provided with a set of transverse convex sheets, and outer convex parts are arranged on the convex sheets. The outer convex parts of the convex sheets and the permeable parts of the folding sides are clamped into combination, and the fin sheets can be connected in series one by one to form a heat radiating sheet integration with the advantages of easy formation, large radiating area and smooth radiating channel.

Description

A kind of fin

Technical field

The utility model provides heat radiating fin structure in a kind of central processing unit that is applied to computer.

Background technology

Along with the central processor CPU arithmetic speed of computer is accelerated day by day, the height of its radiating efficiency also more shows its importance, tradition is applied to the fin 10 ' of the central processing unit 20 ' of computer at present, see also Fig. 5, this fin 10 ' is to be aluminium extruded type or die-casting die, fin 10 ' and central processing unit 20 ' are fitted, fasten with buckling piece 30 ', screw togather fan 50 ' thereon with bolt 40 ' again, be the method that at present general dealer is adopted, if fin 11 ' is thinner, fin 11 ' number is many, the spacing of fin 11 ' is narrower, and its area of dissipation must significantly increase, radiating rate and radiating efficiency also natural energy improve, so, because of its molding mode limited, the adaptation of this fin 11 ' (that is spacing of fin 11 '), and the thickness of fin 11 ' all is defined in certain scope, can't reach requirement; Moreover, desire fan attachment 50 ' thereon the time, must go up boring to screw togather fan 50 ' in fin 10 ', so the thickness because of this fin 10 ' is extremely thick, makes bore operation very difficult! In addition,, itself also can accumulate certain heat and can't distribute safely, after the long-time use, all can damage for central processing unit 20 ' or computer integral body because the thickness of fin 10 ' is extremely thick.

The utility model content

The purpose of this utility model provides that a kind of moulding is easy, area of dissipation is big, heat dissipation channel fin smoothly.

For achieving the above object, solution of the present utility model is: a kind of fin, it is made of one group of fin, the relative both side edges of this fin have identical towards lateral flap, this flanging is provided with hollow part; In the opposite side of this fin, with respect to the hollow part place of aforementioned flanging, be provided with one group horizontal lug, be provided with male part in this lug; The male part of lug and the hollow part of flanging fasten, and are connected in series fin one by one, form passage between each fin.

Described fin is the metal material thin slice with thermal conductive resin.

The male part of described lug is not limited to spherical cambered surface.

The flanging two ends of described fin respectively are provided with a hollow part, and two flangings are provided with four hollow parts altogether up and down.

Described fin is provided with holes, and the passage that forms with fin communicates.

After adopting such scheme, because one group of fin of fin of the present utility model forms, and the hollow part of the male part of each fin lug and flanging fastens, and is connected in series fin one by one, forms passage between each fin.Can realize that moulding is easy, area of dissipation is big, heat dissipation channel fin smoothly.

Embodiment

See also Fig. 1 to Fig. 3, person shown in the figure is the structure of the selected embodiment of the utility model.

Fin 10 of the present utility model is that the fin 11 by plural number is constituted, this fin 11 is stamped to form for the metal material thin slice with thermal conductive resin, in the relative both side edges of this fin 11 have identical towards lateral flap 12, appropriate location in this flanging 12 is provided with hollow part 121, be in the two ends of flanging 12 hollow part 121 to be set respectively shown in the figure, two flangings 12 are provided with four hollow parts 121 altogether up and down; Opposite side in this fin 11, hollow part 121 places with respect to aforementioned this flanging 12, be provided with the horizontal lug 111 of plural number, be provided with male part 112 in this lug 111, this male part 112 can be any standing shape, and the male part 112 of aforementioned lug 111 and the hollow part 121 of flanging 12 are fastened, can be connected in series fin 11 (as shown in Figure 3) one by one, constitute a fin 10 integral body, its fin 11 formed intensive heat dissipation channels 13, but quick heat radiating.

See also Fig. 3 and Fig. 4 again, the fin 10 that assembles with fin 11 is because this fin 11 is punch formings, so its size Control is very easy, even erose fin 10A, if the fin 11A of punching out different size length also one by one snapping assemble, very convenient! In addition, also can holes 14A be set, make holes 14A, 13 pairs of integral heat sink sheets of heat dissipation channel 10A form passage in fin 11A, but then more accelerated heat distribute.
