Description

Heat abstractor

The invention relates to a kind of heat abstractor, be meant especially and a kind ofly assemble convenient, button and keep steady solid and heat abstractor with low cost.

Along with developing rapidly of computerized information industry, the arithmetic speed of corresponding electronic module constantly increases, and increasing along with the electronic building brick arithmetic speed, its heat of supervening also increases severely thereupon, if it is untimely with these heats discharges, stability and quality to the telecommunication transmission will be very unfavorable, discharge the heat that electronic building brick produces so be necessary to set up a heat abstractor.The fixed component kind of existing relevant radiator is a lot, the fixture that the 8521797 No. three patent in Taiwan as shown in Figure 1 discloses, be radiator 20 to be fixed on electronic building brick 30 surfaces by integrally formed fastener 10, wherein this fastener 10 has one for the framework 12 around the radiating fin 22 that is set in radiator 20, this framework 12 also can be pressed on the base plate 24 of radiator 20, extend a button pin 14 simultaneously respectively downwards at this place, framework 12 1 diagonal angle, this button pin 14 can be plugged in the hole 34 of relative set on the circuit board 32.But, this class fastener 10 is in the fastening process, after in the corresponding hole 34 on a button pin 14 insertion circuit boards 32, another 14 on pin of button can have been lifted up and departed from the circuit board 32 another hole 34 accordingly, cause fastening operating difficulties, and if force this button pin 14 of having lifted up to be pressed in the hole 34, this button pin of having lifted up 14 is out of shape even ruptures, and make that to be fitted in the lip-deep heat abstractor integral body of electronic building brick impact resistance very poor.

In addition, also have by two plastic fasteners and realize fastening.As shown in Figure 2, wherein this fastener 40 is sheathed springs 46 on cylinder 42, and make the barb 44 of fastener 40 cylinders 42 ends, pass corresponding through hole 54 on the lug 52 of radiator 50, engage with hole 62 on the circuit board 60 again, thereby the elastic force by spring 46 presses down radiator 50 and is close on electronic building brick 64 surfaces, realizes the purpose (this class formation can be consulted Taiwan the 8321864 No. four and the 852008 No. six patent) of heat absorption and heat radiation.Though but some shortcomings of this fixing means minor betterment said structure need extra additional springs, the whole cost of heat abstractor is improved, very uneconomical.

Purpose of the present invention is promptly to provide that a kind of assembling is convenient, button keeps steady is solid, and heat abstractor with low cost.

Technical characterictic of the present invention is: this heat abstractor mainly comprises a radiator and two clasp nails that are enclosed in this radiator edge and are mutually symmetrical, this clasp nail is integrally formed by plastic material, have a nail portion and two arms, wherein should nail portion have a head than big basal area, one links to each other and the less bar portion of basal area with head, and one link to each other and the bigger basal rod part of basal area with the bar portion other end, this two arm then is to form from the outside vertical extent of this basal rod part other end, in addition, end at this two arm is formed with a sleeve respectively, outwards convex with in the edge for the fixing projection of this sleeve fit and this radiator is corresponding, thereby can radiator be fixed by corresponding hole on the nail portion embedding circuit board.

Compared with the prior art, its advantage is: the clasp nail of this heat abstractor is by being enclosed in the radiator edge, nail portion is difficult for deforming or rupturing, and owing to be that two make-up nail catchers are held heat abstractor, has improved greatly to be fitted in the whole impact resistance of the lip-deep heat abstractor of electronic building brick.

In conjunction with the embodiments the present invention is further described with reference to the accompanying drawings.

Please consult Fig. 3, Fig. 4 and Fig. 5 together, heat abstractor 70 of the present invention comprises that mainly a radiator 80 and two are enclosed in around this radiator 80 and the clasp nail 90 that is mutually symmetrical.

This radiator 80 is to extrude shaping by aluminium, be provided with a base plate 82, its bottom surface 83 is to be used for fitting with the surface of electronic building brick, and then one is convex is provided with some radiating fins 84 for its relative another side, this base plate 82 also convexes with projection 86 respectively in its appropriate position, edge.

This clasp nail 90 is integrally formed by plastic material, be provided with one and can be fixed on nail portion 92 on circuit board or the holder (figure does not show) for clasp nail 90, this nail portion 92 has the head 920 of big basal area, this head 920 tools one fillet surface 922, and further be formed with the conduit 924 of perforation in the central authorities of this head 920, to make things convenient for head 920 when passing circuit board, can produce contraction elasticity, and what be connected this head 920 is the less bar portion 926 of a basal area, what connect these bar portion 926 other ends then is the bigger basal rod part of a basal area 928, simultaneously, when this head 920 after circuit board is passed in extruding and restore, then this bar portion 926 just can have larger area head 920 and basal rod part 928 is fastened in the circuit board by this.In addition, be formed with two arms 94 that can be enclosed in 80 liang of adjacent sides of radiator from the outside vertical extent of the other end of this basal rod part 928, and the projection 86 of these radiator 80 edges relatively, the end of this two arm 94 is formed with a sleeve 96 that can be linked on this corresponding projection 86 respectively, thereby radiator 80 base plates 82 closely can be abutted on the electronic building brick surface.

Fig. 6 is the stereogram of another embodiment of clasp nail of the present invention, this clasp nail 90 ' also be provided with one for nail portion 92 on circuit board or the holder of clasp nail 90 ' can be fixed on ', this nail portion 92 ' also a be provided with tool one routine edged surface 922 ' and the bigger head 920 of basal area ', be connected this head 920 ' also be the less bar portion 926 of a basal area ', but this less bar portion 926 of this head 920 ' relatively ' be eccentric design, this design can make head 920 ' be easier to insert in the circuit board and do not have misgivings of fracture.Connect this bar portion 926 ' the other end be the bigger basal rod part of a basal area 928 ', simultaneously, when this head 920 ' through force be pressed into pass circuit board after, then this bar portion 926 ' just can have larger area head 920 ' and basal rod part 928 ' be arranged in the circuit board by this.In addition, from this basal rod part 928 ' the outside vertical extent of the other end be formed with two arms 94 that can be enclosed in 80 liang of adjacent sides of radiator ', and the projection 86 of these radiator 80 edges relatively, this two arm 94 ' end be formed with respectively one can be linked in sleeve 96 on this corresponding projection 86 ', thereby radiator 80 base plates 82 closely can be abutted on the electronic building brick surface.
