Description

Radiator

Technical field

The present invention relates to a kind of radiator, particularly a kind of fin combination to electronic element radiating.

Background technology

Along with fast development of information technology, the arithmetic speed of central processing unit (CPU) is more and more faster, and the heat of its generation is also more and more, and if too much heat is untimely discharge, the stability when having a strong impact on the central processing unit operation.For this reason, industry is installed a radiator in central processing unit one side usually, to assist to get rid of heat.

As shown in Figure 1, disclosed an existing radiator.This radiator 30 is formed by the mutual buckle of some fin.Each fin comprises a rectangular body 32 and two flangings 34 that bend in the same way from body 32 relative both sides.Each flanging 34 opposite end has further protruded out two installation sheets 38.Each installation sheet 38 upper punch is provided with a salient point 39.Corresponding two installation sheets 38 with body 32 junctions of each flanging 34 offer two button holes 36.The installation sheet 38 of back position fin inserts in the button hole 36 of anteposition fin, the salient point 39 on the installation sheet 38 of position, back and anteposition installation sheet 38 against, thereby make these groups of fins synthesize radiator 30.Yet, only be connected between fin by salient point 39, use and transportation in, salient point 39 very easily comes off and causes fin to separate thereupon from button hole 36, and entire radiator 30 was lost efficacy.

Summary of the invention

In view of this, be necessary to provide a kind of buckle the stable radiator that is difficult for getting loose.

A kind of radiator, form by the mutual buckle of some fin, each fin has a body and is arranged at two clamping parts of the relative both sides of body, each clamping part comprises from outward extending a connecting piece of body and the clasp that extends from brace, described clasp and body are provided with at interval, described clasp has first lamellar body that links to each other with brace and second lamellar body that extends from first lamellar body, the clasp of position, back fin is connected with the mutual buckle of the body of anteposition fin, and first, second lamellar body of position, back fin lays respectively at the both sides, front and back of anteposition heat sink body.

Compared with prior art, the relative both sides of each fin of radiator of the present invention are provided with two clasps, and the clasp of position, back fin is connected with the mutual buckle of the cramp of anteposition fin, and makes radiator have Stability Analysis of Structures.

With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.

Embodiment

As shown in Figure 2, radiator 10 of the present invention is formed by one first fin 11 and some second fin, 13 mutual buckles of being positioned at first fin, 11 1 sides.This radiator 10 is used for contacting to absorb the heat that it distributes with electronic component (figure does not show).

Please consult Fig. 3 and Fig. 4 simultaneously, described first fin 11 is positioned at an end of radiator 10, and it comprises that a rectangle body 110 reaches from vertically extending in the same way two flangings 111 of two minor faces of body 110.The opposite end on body 110 each long limit is provided with two square breach 113.Each square breach 113 have the outer side edges close (figure is mark) with its approaching flanging 111, with outer side edges opposed inside limit (figure is mark) and the vertical fillet (scheming to mark) that is connected outer side edges and inner side edge.One clamping part 115 is formed at body 110 and faces and connect each square breach 113 position.Each clamping part 115 comprises a cramp 1151 that links to each other with square breach 113 fillets and a connecting piece 1153 that outwards bends punching press formation from cramp 1151.This cramp 1151 and body 110 coplanes, with 1153 vertical linking to each other of brace.Brace 1153 is identical with the bearing of trend of flanging 111.This cramp 1151 forms a L shaped stage portion (figure is mark not) with the body 110 of square breach 113 inboards.

The structure of described each second fin 13 is similar to first fin 11.Each second fin 13 comprises a rectangle body 130 and two flangings 131 that extend in the same way from two minor faces of body 130.The opposite end on the long limit of each of body 130 offers two square breach 133.Each square breach 133 have the outer side edges close (figure is mark) with its approaching flanging 131, with outer side edges opposed inside limit (figure is mark) and the vertical fillet (scheming to mark) that is connected outer side edges and inner side edge.One clamping part 135 is formed at body 130 and faces and connect each square breach 133 position.Each clamping part 135 comprises the cramp 1351 that links to each other with square breach 133 fillets, from the outside clasps 1355 that extend of a connecting piece 1353 of forming of bending punching presses and vertical brace 1353 of cramp 1351.This cramp 1351 and body 130 coplanes and with 1353 vertical linking to each other of brace.Brace 1353 is identical with the bearing of trend of flanging 131.This clasp 1355 is the U-shaped structure with opening, and it is by forming with vertical first lamellar bodies 1356 that link to each other of brace 1353, second lamellar body 1357 parallel with first lamellar body 1356 and a connecting piece (figure marks) of being connected first, second lamellar body 1356,1357.Wherein the length of first lamellar body 1356 is than the length of second lamellar body 1357, and first and second lamellar body 1356,1357 all is parallel to body 130.The opening direction of the clasp 1355 of second fin both sides about in the of 13 is oppositely arranged.

Please consult Fig. 5 simultaneously, during assembling, to be placed on corresponding position towards second fin 13 that is provided with

cramp

1151,1351 and

brace

1153,1353 and first fin 11 earlier, the clamping part 135 of position second fin 13 is placed on

cramp

1351,1151 places of anteposition second fin 13 and first fin 11 after making.Use the stamping machine punching press then so that each second fin 13 forms clasps 1355.At this moment, the clasp 1355 of one second fin 13 adjacent with first fin 11 be located on first fin, the 11 corresponding cramps 1151, simultaneously, the clasp 1355 of position, back second fin 13 forms described radiator 10 with cramp 1151 buckles of anteposition second fin 13.First, second lamellar body 1356,1357 of clasp 1355 lays respectively at the both sides, front and back of corresponding cramp 1351,1151.The flanging 111,131 of first,

second fin

11,13 interconnects and the two side faces (figure is mark) that radiator 10 had be parallel to each other, the square breach 113,133 of first,

second fin

11,13 is communicated with and makes radiator 10 have the groove (figure is mark not) of four lengthwises, and the clamping part 115 of described second fin 13 is positioned at groove.

Among the present invention, the

brace

1153,1353 of first and

second fin

11,13 is kept out the right side of clasp 1355, simultaneously, the inner side edge of first and

second fin

11,13 breach is kept out the left side of clasp 1355 and is made first, second fin about 11,13 fixing; The opening direction of the clasp 1355 at the two ends up and down of each second fin 13 is relative again, and makes first and

second fin

11,13 fixing up and down, therefore, and described radiator 10 Stability Analysis of Structures.

Be appreciated that ground, described radiator 10 also can be formed by second fin, 13 mutual buckles.
