Embodiment
Please together see figures.1.and.2, this heat abstractor combination comprises a radiator 10, two fasteners 20 and a circuit board 30.This fastener 20 is used for this radiator 10 is fixed in this circuit board 30.
This circuit board 30 is provided with a heat-generating electronic elements 31, as central processing unit etc., this circuit board 30 is respectively equipped with one first through hole 32 in the outside at these 31 liang of diagonal angles of heat-generating electronic elements, and this two first through hole 32 all is strip, and it is with respect to the distribution that is centrosymmetric of this heat-generating electronic elements 31.
This radiator 10 comprises that a pedestal 11 reaches from pedestal 11 upwardly extending some radiating fins 12.This pedestal 11 roughly is square, and each level of the position at its two diagonal angle extends outward a lug 13, and each lug 13 is provided with one second through hole 14, and this second through hole 14 is strip, and it is aimed at first through hole 32 on this circuit board 30.
Please refer to Fig. 3, this fastener 20 is to be formed by metal lamellar body integrated punching bending, and it comprises that a body 21 reaches by the vertical outwards horizontally extending press section 22 of these body 21 1 ends.This body 21 in the form of sheets, its top is provided with a rectangular punching 23, side from punching 23 tops stretches out and forms a shell fragment 24, this shell fragment 24 is curved, its these body 21 generation elastic deformations relatively, this shell fragment 24 is to be formed by these body 21 integrated punchings, and this punching 23 is shell fragment 24 and is rushed out left hole, back.The free end of this body 21 forms a trapezoidal penetration portions 25, thereby makes the terminal width of body 21 littler than the width of other parts, like this can be so that fastener 20 installations.This body 21 is positioned near the top of this penetration portions 25 that punching press forms two blocks 26 on the sustained height, this block 26 protrudes in the surface of body 21, this two block 26 is on the body 21 between this shell fragment 24 and this penetration portions 25, all roughly be square, this two block 26 is formed at respectively on the dual-side of this body 21, and towards shell fragment 24 with side-prominent and be inclined upwardly, thereby make and form two square breach 27 on the dual-side of body 21, needed space when this two breach 27 as block 26 elastic deformations takes place.Certainly, this block 26 can also be for other shape beyond square, and is as triangle, trapezoidal etc.This press section 22 roughly is square, shell fragment 24 homonymies on itself and this body 21 so that when assembling to these fastener 20 application of forces.
During assembling, earlier radiator 10 is placed on the heat-generating electronic elements 31, make second through hole 14 on the lug 13 of radiator 10 face first through hole 32 on this circuit board 30.The penetration portions 25 of fastener 20 is aimed at this second through hole 14, and the press section 22 of pushing this fastener 20 downwards, elastic deformation after being squeezed, the block 26 of this fastener 20 takes place, thereby make body 21 pass second through hole 14 and first through hole 32 successively, this block 26 restores to the original state and is resisted against on the bottom surface of circuit board 30 afterwards, at this moment, elastic deformation takes place and replaces on the lug 13 of this radiator 10 in the shell fragment on this body 21 24.
Certainly, the fastener among the present invention 20 also can be other forms.As shown in Figure 4, for heat abstractor of the present invention makes up fastener 20a among second embodiment, fastener 20 among this fastener 20a and first embodiment is similar, its difference is: the body 21a of this fastener 20a also outside punching press on the sustained height between this two block 26 forms a block 26a, the incline direction of this block 26a is opposite with the incline direction of original block 26, i.e. the outstanding respectively both sides that are positioned at body 21a of block 26a and block 26.
