The clip comprises a pressing part and a pair of clasp parts extending out from both ends of the pressing part; each clasp part comprises a bending part and a connection arm; the bending part is set around the heat-sink, and a hook is extended from the end of the connection arm; the connection arm passes through the heat-sink and a corresponding side edge of circuit board, and the hook clasps the side surface of the circuit board.
Description
[technical field]
The present invention relates to a kind of heat abstractor, particularly a kind of heat abstractor in order to the heat-generating electronic elements on the circuit board is dispelled the heat.
[background technology]
Along with computer industry constantly develops, electronic component (as central processing unit) running frequency and speed constantly promote, and caloric value is increasing, if untimely eliminating, accumulation of heat causes that temperature raises, and influences the normal operation of heat-generating electronic elements.
The lifting of computing power make memory bar, show that wafer capacity increases day by day on the mode integrated circuit boards such as sound card, volume is more and more littler, operating rate is piece more and more, the heat that produces in this process constantly increases, how fast the wafer heat on these additional card effectively to be distributed fast, also become the problem that present dealer need solve.
Usually industry is installed auxiliary its heat radiation of radiator on electronic component, contacts close and firm for making radiator with heater element, needs to realize that by a fastener radiator is connected with the firm of this heater element.
Yet because element gathers on the integrated circuit board, the space is little and adjacent integrated circuit board spacing is narrow, and the radiator inconvenience directly is installed thereon, very easily is adjacent integrated circuit board generation interference, operation inconvenience because of radiator is installed on an integrated circuit board.In addition, the fastener that cooperates with socket on the existing CPU of being used for of screw is difficult to use because of can not find the corresponding matching structure on integrated circuit board traditionally.
[summary of the invention]
In view of this, be necessary to provide a kind of easy accessibility, fasten firm heat abstractor.
The heat abstractor of the embodiment of the invention is in order to dispel the heat to the heat-generating electronic elements on the circuit board, this heat abstractor comprises a radiator and a fastener, this fastener comprises and is used to compress a pressure section of this radiator and oppositely bends extended a pair of buckling parts by these pressure section two ends, each buckling parts comprises kink that is extended by the bending of pressure section one end and a linking arm that is extended by the kink end, this kink winding is in the radiator periphery, a grab is extended in the terminal bending of linking arm, this linking arm is through radiator and circuit board relative side and grab hook circuit board one side surface, offer a L shaped aperture of passing for fastener one linking arm on the described circuit board, this aperture comprises that one first orifice part reaches and perpendicular one second orifice part that is communicated with of this first orifice part, and the grab of above-mentioned linking arm passes this first orifice part and slips into second orifice part.
This execution mode compared with prior art, fastener cooperates with circuit board radiator is pressed on the circuit board among the present invention, easy accessibility fastens firm.
With reference to the accompanying drawings, the invention will be further described in conjunction with the embodiments.

[embodiment]
See also Fig. 1 to Fig. 2, heat abstractor of the present invention comprises a circuit board 10, a radiator 20 and radiator 20 is fixed on the fastener 30 of circuit board 10 1 sides.
These circuit board 10 upper surfaces are provided with a heat-generating electronic elements 40, and the lower surface of above-mentioned radiator 20 directly is sticked on this heat-generating electronic elements 40.This circuit board 10 is rectangular, comprises a pair of long limit and pair of short edges, and this edge, circuit board 10 1 long limit is provided with a notch 12, and this notch 12 extends perpendicular to circuit board 10 long side directions; Be provided with an aperture 14 near another place, long limit, this aperture 14 is roughly L-shaped, comprises first orifice part 140 and second orifice part 142 that is communicated with first orifice part.This first, second orifice part 140,142 bearing of trends are parallel respectively, perpendicular to the long limit of circuit board 10.
This radiator 20 comprises that a base plate 22 that directly contacts with heat-generating electronic elements 40 reaches by the vertically extending some radiating fins 24 of these base plate 22 upper surfaces.Notch 12, aperture 14 on these base plate 22 1 opposite side corresponding circuits plates 10 are provided with a pair of breach 26.
See also Fig. 2 and Fig. 3, the pressure section 32 of this fastener 30 is pressed on base plate 22 upper surfaces of radiator 20, kink 330 be set around radiating fin 24 peripheral and with pressure section 32 antarafacials.Linking arm 332 is fastened in base plate 22 and circuit board 10 both sides, and grab 334 reverse hooks are at circuit board 10 lower surfaces.Above-mentioned pressure section 32 presses in base plate 22 upper surfaces because of being subjected to elastic force, and kink 330 relative circuit board 10 reverse perks and pressure section 32 tilt.
See also Fig. 1 to Fig. 4, during assembling, radiator 20 is placed on the circuit board 10, fastener 30 a wherein linking arm 332 breach 26, the notch 12 on the circuit board 10 that pass base plate 22 1 sides in turn is resisted against circuit board 10 lower surfaces with the grab on it 334, mobile fastener 30 passes through the breach 26 of base plate 22 another sides, first orifice part 140 on the circuit board 10 in turn with another linking arm 332, mobile again fastener 30 finally slips in second orifice part 142 another linking arm 332, and with grab on it 334 and last grab 334 reverse hooks at circuit board 10 lower surfaces.Pressure section 32 is pressed on base plate 22 upper surfaces, thereby fastener 30 is pressed on circuit board 10 1 sides with radiator 20 and closely contacts with heat-generating electronic elements 40.
