Abstract

The utility model discloses a buckling structure for laptop heat dissipating fins. The buckling structure comprises a heat dissipating subassembly which is composed of a plurality of buckled single-chip heat dissipating fins; two sides of one end of each heat dissipating fin are shaped with a first bent part and a second bent part; the edges of the first bent part and the second bent part bend towards each other to develop into a first hem and a second hem; a first pothook and a second pothook are respectively arranged on the first hem and the second hem; a first connecting hole and a second connecting hole are respectively arranged on the main body of the heat dissipating fin corresponding to the first pothook and the second pothook; a third bent part bending in the same direction with the first bent part and the second bend part is arranged at the other end of the heat dissipating fin; a third pothook is arranged at the edge of the third bent part and a third connecting hole corresponding to the third pothook is arranged on the third bent part; when all the heat dissipating fins are connected, the first pothook and the second pothook are respectively hitched in the first connecting hole and the second connecting hole, while the third pothook is hitched in the third connecting hole. The buckling structure is firm and is low in cost and good in heat dissipating effect.

Description

The buckling structure of radiating fin for portable computer

Technical field

The utility model relates to a kind of radiating fin, especially a kind of buckling structure of radiating fin for portable computer.

Background technology

The radiating fin that present laptop computer is used has a variety of structures, the employing that is connected with of each heat radiator is established a connecting link in addition heat radiator is together in series, what have establishes a hook and a connecting hole in addition at the heat radiator side, places connecting hole to finish the connection of multi-disc heat radiator by hook.Right these structures make that the radiating fin strength of joint is low, production cost is high and thermal diffusivity is not good.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of fastening structure of radiating fin for portable computer, and this fastening structure makes that the radiating fin cost is low, connecting fastness, to reach radiating effect by force better.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of buckling structure of radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin one end dual-side form in the same way first, two kinks, first, two kink edges (promptly to the body center) bending more in opposite directions form first, two flangings, first, form first respectively on two flangings, two hooks, corresponding first, the body of two hook radiating fins is provided with first, two connecting holes, the radiating fin other end is formed with and first again, two kinks the 3rd kink in the same way, the 3rd kink edge forms the 3rd hook, form the 3rd connecting hole on corresponding the 3rd hook the 3rd kink, when each radiating fin links to each other, first, two link up with respectively, and correspondence is placed in first, in two connecting holes, the 3rd hook correspondence is placed in the 3rd connecting hole.

Further technical scheme of the present utility model is: first and second kink shape on the radiating fin is identical, and first, second and third hook on every radiating fin is identical with first, second and third connecting hole position.

First, second and third kink and the radiating fin body of radiating fin are rectangular, and first and second flanging is rectangular with first and second kink respectively.

The opening of first and second hook is towards the radiating fin other end, and the opening of the 3rd hook is towards radiating fin one end (opening that is first and second hook is relative with the opening of the 3rd hook).

The beneficial effects of the utility model are: when each radiating fin linked to each other, first and second linked up with respectively that correspondence is placed in first and second connecting hole, and the 3rd hook correspondence is placed in the 3rd connecting hole.A slice radiating fin three hooks in back are in three connecting holes of a slice radiating fin before correspondence is equipped in like this, determine a plane at 3, this spline structure fastness is good, cost is low, can guarantee that again the ventilation distance that heat radiator vertically reaches between every heat radiator equates, collateral security thermal diffusivity preferably, and appearance looks elegant.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a monolithic heat radiation fin structure synoptic diagram described in the utility model;

Fig. 2 is that most sheet radiating fin described in the utility model fastens the back structural representation;

Embodiment

Embodiment: a kind of buckling structure of radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin one end dual-side form in the same way first, two

kinks

11,12, first, two kink edges (promptly to the body center) bending more in opposite directions form first, two

flangings

21,22, first, form first respectively on two flangings, two

hooks

31,32, corresponding first, the body of two hook radiating fins is provided with first, two connecting

holes

41,42, the radiating fin other end is formed with and first again, two kinks the 3rd kink 13 in the same way, the 3rd kink edge forms the 3rd hook 33, form the 3rd connecting hole 43 on corresponding the 3rd hook the 3rd kink, when each radiating fin links to each other, first, two link up with respectively, and correspondence is placed in first, in two connecting holes, the 3rd hook correspondence is placed in the 3rd connecting hole.

Manufacture process of the present utility model is: first, second and third hook of back a slice radiating fin is corresponding respectively to get final product in first, second and third connecting hole of a slice radiating fin before being placed in, by that analogy, finish the connection of multi-disc radiating fin, thereby constitute the radiating fin subassembly.
