Abstract

The utility model discloses a new buckling structure for laptop heat dissipating fins. Two sides of the main body of a heat dissipating fin are provided with an upper bent leg and a lower bent leg; both the upper bent leg and the lower bent leg comprise a first bending part, a second bending part and a third bending part; the first bending part bends from the side of the main body of the heat dissipating fin; the second bending part extends from the end of the first bending part, a clearance is left between the lower edge of the second bending part and the main body of the heat dissipating fin, and the upper edge of the second bending part stretches out of the upper edge of the first bending part; the third bending part shrinks into the lower edge of the second bending part. When all the heat dissipating fins are connected, the second bending parts of the upper and the lower bent legs of the next heat dissipating fin support the edge of the heat dissipating fin and the upper edge of the next heat dissipating fin is disposed in the clearance, while the third bending part bend inwards towards the main body of the heat dissipating fin to be clipped on the main body of the heat dissipating fin. In this way, the main bodies of two heat dissipating fins can be connected.

Description

The buckling structure of novel 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 novel 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 novel radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin body both sides form respectively at interval in the same way two and go up bending pin and two bending pin down, on, under bend pin all by first, two, three kinks are formed, first kink is turned up in radiating fin body side, second kink extends the first kink end and the second kink lower limb and radiating fin body certain interval, the second kink coboundary protrudes from the first kink coboundary, the 3rd kink extends the second kink end, and the 3rd kink coboundary protrudes from the second kink coboundary, the 3rd kink lower limb indentation is in the second kink lower limb, when each radiating fin links to each other, on back a slice radiating fin, second kink that bends pin down is supported in the radiating fin body edges and its upper rim correspondence places described gap, the bending in the radiating fin body of the 3rd kink is equipped on the radiating fin body, and the two radiating fin bodies in front and back have just linked to each other like this.

The upper and lower bending pin shape of radiating fin is identical.

Described first kink and radiating fin body are rectangular.

The beneficial effects of the utility model are: when each radiating fin links to each other, second kink of the upper and lower bending pin of back a slice radiating fin is supported in the radiating fin body edges and its upper rim correspondence places described gap, the bending in the radiating fin body of the 3rd kink is equipped on the radiating fin body, and the two radiating fin bodies in front and back have just linked to each other like this.The 3rd kink of back a slice radiating fin bending pin is equipped on the body of preceding a slice radiating fin like this, the structure fastness is good, and 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 the structural representation after most sheet radiating fin described in the utility model fastens;

Embodiment

Embodiment: a kind of buckling structure of novel radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin body both sides form respectively at interval in the same way two and go up bending pin 1 and two bending pin 2 down, on, under bend pin all by first, two, three

kinks

11,12,13 form, first kink 11 is turned up in radiating fin body side, second kink 12 extends the first kink end and the second kink lower limb 8 has certain interval 3 with the radiating fin body, the second kink coboundary 4 protrudes from the first kink coboundary 5, the 3rd kink 13 extends the second kink end, and the 3rd kink coboundary 6 protrudes from the second kink coboundary 4,7 indentations of the 3rd kink lower limb are in the second kink lower limb 8, when each radiating fin links to each other, on back a slice radiating fin, second kink 12 that bends pin down is supported in the radiating fin body edges and its coboundary 4 part correspondences place described gap, the bending in the radiating fin body of the 3rd kink is equipped on the radiating fin body, and the two radiating fin bodies in front and back have just linked to each other like this.

The upper and lower bending pin shape of radiating fin is identical.

Described first kink and radiating fin body are rectangular.

Manufacture process of the present utility model is: second kink of the upper and lower bending pin of back a slice radiating fin is supported in the radiating fin body edges and its upper rim correspondence places described gap, the bending in the radiating fin body of the 3rd kink is equipped on the radiating fin body, and the two radiating fin bodies in front and back have just linked to each other like this.
