Description

The syndeton of fin

Technical field

The utility model relates to a kind of syndeton, particularly a kind of syndeton that applies to the thin slice of cooling computer equipment work temperature and connect the fin in the formula radiator.

Background technology

Electronic technology has marched toward little and beautiful boundary under the drive of integrated circuit, especially the processor as electronic equipment more represents surprising computing capability under described technology.Yet disposal ability also produces the working temperature of high heat relatively excessively fast.So how the long-pending heat in the remover apparatus becomes another problem that will overcome of engineer then.

For driving away the particularly long-pending heat of central processing unit of computer equipment, existing technology is to adopt collocation that the radiator of fan is arranged, utilize aluminium extruded type fin in the described radiator or punching press thin heat radiation sheet to be affixed on described central processing unit surface and absorb its working temperature, utilize the fan of groups of fins top to reduce long-pending heat on the fin again.In two kinds of above-mentioned fin patterns, the aluminium extruded type fin is owing to be to extrude described fin with the mould pull, so in the slimming of considering to have limited under the intensity of fin its thickness, therefore described kind of fin can't increase the sheet number to promote radiating efficiency by the thickness attenuation.With respect to the aluminium extruded type fin is the restriction of thickness, and punching press thin heat radiation sheet is to be made by the thin material punching press, thus on thickness, possess preferable advantage, but the described kind of problem that fin also has it to overcome.

Because the thickness of every of punching press thin heat radiation sheet as thin as a wafer but need every and linked, therefore in the design of syndeton, need put forth effort especially, syndeton with existing a kind of this type fin, (seeing also Fig. 1), the ora terminalis up and down of each sheet fin 2 has a bending edge 20, establish a pair of syndeton 21 on its open end, establish a short protuberance that makes progress 23 in bending edge 20 and heat sink body 22 joints and establish a groove 24 with respect to the reverse position of described short protuberance 23; The fin of above-mentioned structure, be utilize will back one fin the mode that is resisted against in the groove 24 of last fin of short protuberance 23 fin is connected to groups of fins in twos.Above-mentioned fin since before and after just utilizing the short protuberance 23 of fin and groove 24 simply replace binding, event is relatively poor in conjunction with stable degree with this groups of fins that is connected to, entire heat dissipation sheet group often forms the gabion shape of distortion, and described phenomenon can cause groups of fins can't be closely connected in the central processing unit surface with its long-pending heat of complete absorption.In addition, the syndeton of described fin is also comparatively fragile, causes the improper separation of fin easily.

Summary of the invention

The purpose of this utility model is to provide a kind of to be had firmly in conjunction with effect, and can promote to have after the moulding syndeton of the fin of excellent external form stability.

For reaching above-mentioned purpose, the utility model provides a kind of syndeton of fin, be meant the syndeton that is applied in thin slice and connects the fin in the formula radiator especially, it is provided in a side of on the ora terminalis up and down of fin at least more than one, and comprise by the extended tabs in heat sink body edge with a width, itself and adjoining place, heat sink body edge form a hollow hole, the tabs ora terminalis that is relative position with described hollow hole is established a tongue piece, described tongue piece in two fin in conjunction with the time, be that bending button is butted in the adjacent heat sink body medial surface towards described hollow hole; In addition, two ends of described tabs can be bent with the end angle downwards and be resisted against between the relative inside and outside side of two heat sink body.

In above-mentioned structure, the body side that is butted on adjacent fin is detained in the terminal bending of the opening (unsettled) of described tongue piece, can make each fin reach best bond strength, to avoid fin by improper separation.Again, two ends angle bending down with described tabs, can two fin in conjunction with the time be resisted against between the relative inside and outside side of two heat sink body, two fin are resisted mutually and under the gap that nothing is vacillated, provide the radiator of being formed with described fin to have and stablize indeformable external form.

Below only cooperate illustration preferred embodiment of the present utility model.

Description of reference numerals: 1 fin; 11 tabs; 12 hollow holes; 13 tongue pieces; 13 ' tongue piece; 14 bodies; 15 end angles; 15 ' end angle.

Embodiment

One specific embodiment structure of the syndeton of the utility model fin, as shown in Figure 2, it is provided in a side of the ora terminalis up and down of fin 1, and the increase and decrease of the length of the visual fin 1 of quantity, but respectively establish one to being less than contiguous each corner place.Described syndeton comprises from heat sink body 14 edges extends the tabs 11 provide a proper width, and itself and adjoining place, heat sink body 14 edges form a hollow hole 12, and forms a tongue piece 13 with ora terminalis that described hollow hole 12 is the tabs 11 of relative position; Again, the both-side ends of described tabs 11 each be bent with an end angle 15 downwards.

Syndeton as shown in Figure 2, it is carrying out and during in conjunction with the fin of each sheet, be in the hollow hole 12 of a slice fin 1 before penetrating by tongue piece 13 with back a slice fin 1, and example structure of the present utility model can increase to the length of described tongue piece 13 above the length of hollow hole 12 on tabs 11, so that when assembling each fin, a slice heat sink body 14 is towards the medial surface of described hollow hole 12 before utilizing diel along band its bending button to be butted on, with and tail end upwards be resisted against before tabs 11 bottom surfaces of a slice fin, as shown in Figure 3, make 1 of each fin of combination thus except that having good consolidation effect, described hollow hole 12 can be covered by described tongue piece 13 again and present preferable outward appearance.But described hollow hole 12 can be not yet by tongue piece 13 ' cover, this moment tongue piece 13 ' length needn't surpass the length of hollow hole 12, and directly tongue piece 13 ' bending button is butted on the medial surface of preceding a slice heat sink body 14, as shown in Figure 5.

In addition, the two side ends angle 15 of tabs 11 two fin 1 in conjunction with the time, the end angle of back a slice fin 1 is the inside and outside side that supports to arrive in two heat sink body 14, and its mode of supporting to arrive in is the body surface (as Fig. 4) that adopts perpendicular to preceding a slice fin 1, the auxiliary above-mentioned tongue piece 13 of energy combines with hollow hole 12, stablizes indeformable external form and provide the radiator of being formed with described fin to have.

In the preferable enforcement structure of above-mentioned the utility model, tabs 11 both sides of described fin 1 are the end angle 15 of bending downwards, on concrete enforcement, described two ends are not cut from bending again on described heat sink body 14 downwards to be necessity, to be the kenel that does not link to each other to shown in Figure 4 with described heat sink body 14 with Fig. 2; Other feasible mode end angle 15 ' with tabs 11 still all right directly bends downwards, is the kenel that links to each other with described heat sink body 14, and as shown in Figure 6, and the angle of its bending is not exceeded with 90 degree yet.So the above end angle 15 or 15 ' that is located at tabs 11 dual-sides is to comprise any bending shape and angle.

The execution mode of the syndeton of the utility model fin and function are to prove absolutely as above, the above is preferred embodiment of the present utility model but not structural limitations of the present utility model, all those skilled in the art, according to other simple reformation that the technology of taking off before the utility model is done, be all in the claim covering scope of the present utility model.
