Abstract

A clamping structure of a radiation fin is formed by fastening and overlaying a plurality of radiation fins continuously; the radiation fin is L-shaped, and comprises a body and a flanging extended along a lower edge of the body; an upper edge of the body bends downward along a side and extends to form the two cramps; an upper part on the body corresponding to the cramp extends outward along another side and is provided with the two opposite approximate L-shaped retaining pieces to hold the cramp of the adjacent radiation fin, thereby joining a plurality of radiation fins together continuously.

Description

The fin interface arrangment

[technical field]

The utility model refers to the very firm stacked-up type fin interface arrangment of a kind of multi-disc joint in parallel especially about a kind of fin interface arrangment.

[background technology]

Along with the fast lifting of electronic component operating frequency, the heat that it produced is also increasing, and too high temperature will have a strong impact on the electronic component stability in when operation, so the heat dissipation problem utmost point of electronic component need solve.

In the traditional heat-dissipating mode, mostly adopt at the end face of electronic component such as the central processing unit radiator of fitting.This class radiator in the past, be that one-body molded several are used to increase the fin of area of dissipation on metal base mostly, yet under restrictions such as manufacturing technology and mould strength, the quantity of the fin that can be processed to form and highly limited, therefore the integral heat sink area is restricted, and is difficult to meet more and more high heat radiation needs.

For addressing the above problem, industry adopts a kind of folded heat sink, and as No. the 87208039th, Taiwan patent application, this fin is back and forth to be bent into wavy continuously and to be formed by metal sheet, therefore, can improve the integral heat sink area by suitable increase number of inflections and reach preferable radiating effect.But in this design, the contact area between this fin and the pedestal has only half of interface entire area usually, and heat conduction contact area between the two is very limited, so be difficult to effectively heat is transmitted on the fin by pedestal.

Recently, though there is the people to improve out with the multi-disc fin radiator that constitutes that engages in parallel, it is in that to make fit on comparatively simple, thereby cost of manufacture is lower, as No. the 00209935.7th, Chinese patent.The top of the fin of this radiator and bottom are respectively equipped with a clip connection device, this clip connection device is to be indentations, the mode that fastens by front and back cooperates the interlocking effect that reaches between fin with the clip connection device of adjacent fin, and then prevents that to a certain extent fin from deformation taking place when suffering external force.But the clip connection device of this fin is positioned at the fin bottom and is indentations, and this structure can influence the smoothness of fin bottom, and then being connected between fin and substrate caused harmful effect.In addition, this radiator is by certain deformation of fin buckle structure to be fastened mutually, and this manner expends the plenty of time, and then influences production efficiency.

Therefore, how to provide a kind of multi-disc joint in parallel and very firm stacked-up type fin interface arrangment, real is problem to be solved in the utility model.

[summary of the invention]

The purpose of this utility model is to provide a kind of stacked-up type fin convenient, that joint is firm of assembling.

The purpose of this utility model is achieved through the following technical solutions: a kind of fin interface arrangment, and it is that its each fin is the L type with stacked the forming of the continuous snapping of some fin, comprises that a body and is from the extended flanging of body root edge; This body apical margin is extended with two cramps along bending under the side direction, and corresponding each cramp position, body top sets out two blocked pieces that roughly are the L type in opposite directions along opposite side to outwash, to hold the cramp of adjacent fin, by this some fin are bonded together continuously.

Owing to adopted technique scheme, the utility model fin interface arrangment has following advantage at least: 1, assembling is convenient, joint is firm; 2, suitable with a large amount of fast productions of progressive press tool, to reduce production costs; 3, can be bonded into the radiator of different length, size on demand.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 4 is the partial enlarged drawing of Fig. 3.

Fig. 5 is the constitutional diagram that the some fin of the utility model combine with pedestal.

[embodiment]

See also Fig. 1 to Fig. 5, the utility model provides a kind of stacked-up type heat radiating fin structure, and it is that continuous snapping is stacked forms with some fin 10.

This fin 10 is to become the L type by the good material integrated punching of thermal conductivity such as aluminium or copper, comprises a body 12 and a flanging 14 that vertical bending forms from body 12 bases.Two cramps 16 are extended along bending under the side direction in these fin 10 apical margin two ends, set out a retaining along opposite side to outwash in corresponding each cramp 16 position of body and put portion, and this retaining is put portion and is made up of two in opposite directions blocked pieces that approximately are the L type 18.Each blocked piece 18 end all tilts to the body direction, so that the elastic force of clamping to be provided.Each retaining is put and is surrounded an accommodation space (not indicating) between portion and the body 12 to hold the corresponding cramp 16 of adjacent fin 10.More inside inflection one segment distance of the not end of this cramp 16 forms a folding part 17, replaces mutually with the root edge of blocked piece 18 after making its accommodation space that enters adjacent fin, to reach more firm fastening.

During assembling, the cramp 16 of fin 10 is inserted in the accommodation space of the fin 10 that is adjacent, can engage the fin 10 of varying number by different needs; The flanging 14 of each fin 10 is all towards same direction, and forms a plane jointly and pedestal 20 fits tightly.

Claims
