Abstract
The utility model is applied to the field of heat dissipating structures, providing a fin roots folding type heat dissipating device. The heat dissipating device comprises at least two heat dissipating fins which are arranged at intervals and in parallel and a heat dissipating base, wherein the roots of the fins are upward and circuitously folded to be formed into a thickening part, the folding number of the circuitous folding is at least to be one, and the heat dissipating base is provided with a groove which is matched with the thickening part. The fin roots folding type heat dissipating device has reasonable and reliable product structure, and can improve the product production efficiency and reduce the product cost since the roots of the fins are upward and circuitously folded to be formed into the thickening part.
Description
Technical field
The utility model belongs to the radiator structure field, relates in particular to a kind of heat abstractor of fin root folded form.
Background technology
As Fig. 1～shown in Figure 6, at present, the radiating fin 91 in the heat abstractor is all pegged graft on the heat dissipation base 92, is specially and offers some grooves 921 on heat dissipation base 92, then radiating fin 91 is directly inserted in the groove 921.In the prior art, the shape of cross section of radiating fin 91 is a linear, and the size of the width of the thickness of radiating fin 91, groove 921 is identical, the thinner thickness of radiating fin 91, cause the generous narrower of groove 921, processing difficulties, production cost height, efficient are low.When the gauge of radiating fin 91 is t, by way of the prior art, need the width of groove 921 is machined to t, then needing used thickness is that the saw blade of t is processed, but bad phenomenon such as saw blade distortion appear in thin excessively saw blade self intensity difference easily in process, for avoiding this phenomenon, can only reduce process velocity, reduce the feed speed of saw blade, cause working (machining) efficiency low like this, the production cost height.As use the thicker radiating fin of material thickness 91, and then cause material cost height and product quality big, be unfavorable for the lighting of product.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of heat abstractor of fin root folded form is provided, and its product structure is rationally reliable, can improve production efficient and reduce product cost.
The utility model is to realize like this, a kind of heat abstractor of fin root folded form, comprise a radiating fin and a heat dissipation base that at least two spaced and parallel are arranged, it is characterized in that: the upwards circuitous thickening part that is folded to form of the root of described radiating fin, described circuitous folding broken number is at least one, offers the groove that is complementary with described thickening part on the described heat dissipation base.
Preferably, described radiating fin adopts the metal material manufacturing.
Preferably, described heat dissipation base adopts the metal material manufacturing.
Preferably, described heat dissipation base adopts the mode moulding of mach mode or extrusion molding.
Particularly, offer some installation through holes on the described heat dissipation base.
Further, also be installed with at least one radiator fan above the described radiating fin.
The heat abstractor of a kind of fin root folded form provided by the utility model, its product structure is rationally reliable, upwards make a circulation to be folded to form a thickening part by root, both can improve the intensity and the radiating effect of fin, also can improve production efficient and reduce product cost radiating fin.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 7～shown in Figure 12, the heat abstractor of a kind of fin root folded form that present embodiment provided, comprise a radiating fin 11 and a heat dissipation base 12 that at least two spaced and parallel are arranged, the root of described radiating fin 11 upwards makes a circulation folding and forms a thickening part, described circuitous folding broken number is at least one, offers the groove 121 that is complementary with described thickening part on the described heat dissipation base 12.Preferably, it is one that present embodiment is provided with circuitous folding broken number, thereby the thickness that makes the thickening part is the twice of the material thickness of radiating fin 11, accordingly, the width dimensions of described groove 121 can be machined to the twice of the material thickness size of radiating fin 11, compare with the mode that groove 121 width in the conventional art are consistent with the material thickness of radiating fin 11, the heat abstractor of a kind of fin root folded form provided by the utility model, it folds and forms the thickening part by the root with radiating fin 11, can allow groove 121 sizes of described heat dissipation base 12 widen, can use thicker saw blade processing maybe can adopt and squeeze the moulding of aluminium mode, thereby greatly facilitate the processing of groove 121, promoted the technological level of gear shaping fin heat abstractor, can adopt the bigger cutter of gauge that groove 121 is processed, the processing feed speed increases, save the process time of groove 121, cutter is difficult for producing distortion, bad phenomenon such as fracture, the working (machining) efficiency height has reduced production cost.And fold by root, the radiating fin 11 and the contact area of heat dissipation base 12 are increased, the heat on the heat dissipation base 12 is transmitted on the radiating fin 11 fast, help improving the radiating effect of product radiating fin 11.
Preferably, described radiating fin 11 adopts the metal material manufacturing, specifically can adopt aluminum or copper product manufacturing, its good heat conductivity, and can adopt the diel moulding, the production efficiency height.
Preferably, described heat dissipation base 12 adopts the metal material manufacturings, specifically can adopt aluminum or copper product manufacturing, its good heat conductivity, and can adopt extrude, the diel moulding, the production efficiency height.
