Description

Fin with buckling and clamping structure

Technical field

The utility model is about a kind of fin with buckling and clamping structure, especially about thin shape metal fin a kind of closing in a row, that have buckling and clamping structure.

Background technology

With existing heat abstractor is example, its contain usually fin in a row for treat that radiating piece reclines and combine, to cooperate the auxiliary conduction of active cooling package and heat abstractor, dispel the heat for various heat-producing devices.Therefore, promptly form necessary large tracts of land heat conduction member by the fin that most fin constituted.

In existing heat abstractor, though the integrated radiating piece that can be constituted with the high thermal conductivity material is arranged, generally cost is higher.As for the structure with the synthetic row of most groups of fins, then involving must be at location of fin use in twos and winding member, and not only constituent components is uneconomical for it, and trouble and bothersome is processed also in follow-up assembling.Though and existing this class heat abstractor has to dash between fin in twos and establishes relative sags and crests, for being engaged with each other the location in a row, its combined structure is quite undesirable.

Summary of the invention

In order to overcome the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of fin with buckling and clamping structure, its can be directly on fin rapidly punch forming go out wedging position, make in twos fin locating engagement really, and suitable continous way punch die automatic job, save manpower, time, reduce cost.

For reaching above-mentioned purpose, the utility model provides a kind of fin, respectively establish a preceding flanging that contains the Access Division at the ora terminalis up and down of the vertical lamellar body of fin, this Access Division punches out the buckling groove that contains back segment broad clamping mouth together respectively, and run through the lamellar body ora terminalis backward and make a notch part, two left and right sides clamping ears that have inboard grab are relatively then extended in its open front; Make above-mentioned left and right sides clamping ear snap in the back segment clamping mouth of the adjacent fin in the place ahead, and cooperate grab clip location, the left and right sides.

Described clamping mouth and left and right sides clamping ear are made as beloid with shape.The grab invagination of described left and right sides clamping ear meets at right angles, with the notch part of the relative ora terminalis of the adjacent fin in clip the place ahead.Catch in the middle of the notch part of described lamellar body ora terminalis reserves one in clamping mouth rear end is to cooperate the buckling groove width.Be converted into inclination in the grab of described left and right sides clamping ear, the middle catch of being reserved with clip the place ahead adjacent fin ora terminalis notch part.

In sum, the utility model can be directly on fin rapidly punch forming go out wedging position, make the certain locating engagement of fin in twos, and suitable continous way punch die automatic job, save manpower, time, reduce cost, possess industrial value.

The specific embodiment

The utility model is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof are enumerated feasible embodiment and conjunction with figs. is illustrated by following, so that global design is more clear.

In possible embodiments, the grab invagination of the above-mentioned left and right sides clamping ear state that meets at right angles is with the notch part of the relative ora terminalis of the adjacent fin in clip the place ahead.

And among another embodiment, be converted into inclination in the grab of this left and right sides clamping ear, the middle catch of being reserved with clip the place ahead adjacent fin ora terminalis notch part.

See also Fig. 1, in the fin of the in type improvement structure of diagram, the ora terminalis up and down 13,14 of metal foil shape lamellar body 10 curved respectively establish extend a short shape before flanging 11,12, spacing effect when providing fin in twos to engage then is preset with the

Access Division

20,21 of stretching out respectively forward at this preceding

flanging

11,12.

Same relatively shape is made in above-mentioned Access

Division

20,21, and belongs to identical procedure, therefore only shows Access Division 20 wherein in Fig. 2.Access Division 20 punches out the buckling groove 22 that contains back segment broad clamping mouth 23 together, and the relative ora terminalis 13 that backward runs through lamellar body 10 makes a notch part 17, and two relative left and right

sides clamping ears

24,25 are then extended in its open front forward.Inboard each outstanding one toward each

other grab

26,27 further is converted into

grab

26,27 rectangular-shaped inwardly before the clamping

ear

24,25.

In preferred embodiment, above-mentioned clamping mouth 23 is made as match trapezoidal with left and right

sides clamping ear

24,25, and constitutes narrow front and wide rear.And the notch part 17 of lamellar body 10 is reserved a middle catch 15 in clamping mouth 23 rear ends, to cooperate the width of buckling groove 22.

In the fin forming process, at first as shown in Figure 3, dash in lamellar body 10 ora terminalis appropriate locations and to set out buckling groove 22, clamping mouth 23, middle catch 15, notch part 17, left and right

sides clamping ear

24,25 and left and right sides grab 26,27, shown in Figure 4 for another example with left and right sides grab 26, the 27 invaginations state that meets at right angles, quarter bend folds preceding flanging 11 among Fig. 2 forward then, and then constitutes above-mentioned Access Division 20.

According to the structural design of above-mentioned Access Division 20, making in twos, fin can and be abutted against state shown in the composite diagram 5,6,7.With lamellar body 10 toward antecurvature go out before flanging 11, then left and right

sides clamping ear

24,25 snaps in the back segment clamping mouth 230 of the adjacent heat radiation lamellar body 100 in the place ahead, and its buckling groove 22 is nested with the middle catch 150 of lamellar body 100, the notch part 170 that cooperates left and right sides grab 26,27 clip lamellar bodies 100 relative ora terminalis again, reach infallible buckling and clamping effect, so clamping connection promptly can be made into the fin in a row shown in the 7th figure in regular turn.

In another embodiment shown in Figure 8, the left and right

sides clamping ear

24,25 of lamellar body 10 snaps in the clamping mouth 230 of the adjacent lamellar body 100 in the place ahead equally, to be converted into inclination in the left and right sides grab 261,271 again,, reach firm clamping locating effect with the middle catch 150 of clip the place ahead lamellar body 100 ora terminalis.
