Embodiment
See also Fig. 1 to Fig. 4, heat abstractor combination of the present invention comprises a radiator 20 and a fastener 30.This fastener 30 is installed on the radiator 20, and combines with circuit board 50 and radiator 20 is closely adhered on the electronic component, and wherein this electronic component is installed on the circuit board 50, and this circuit board 50 is formed with a clasp 51 respectively at the diagonally opposing corner of electronic component.
This radiator 20 is formed by a pedestal 21 and from some radiating fins of these pedestal 21 end face vertical extent and parallel interval arrangement, and this radiating fin comprises first fins group 23 and second fins group 25.First fins group 23 and second fins group 25 are positioned at the middle part of pedestal 21 and leave a segment distance with the dual-side of pedestal 21, and it is disymmetrical along portion 29 that pedestal 21 is formed.First fins group 23 is highly lower than second fins group 25, and adjacent respectively row all forms a groove 27 between radiating fin.
This fastener 30 is articulated by connector by two metallic rod bodies that bend continuously and forms, and mainly comprises a buckling piece 31, a regulating part 35 and two connectors 37.Wherein, this buckling piece 31 articulates with this two connector 37 respectively with regulating part 35; So, can pass through adjusted part 35, make connector 37 motions and make buckling piece 31 motions, thus the size of 30 pairs of radiator 20 active forces of scalable fastener.Below be further described at the structure of tool 30.
Regulating part 35 comprises a location division 351 and two arms 353.This regulating part 35 roughly takes the shape of the letter U, and its 351 two ends, location division vertically extend two arms 353 respectively, this two arm 353 be positioned at radiating fin both sides and two arms, 353 ends respectively bending to the inside extend to form two and cooperate section 357.
Be arranged at intervals with two pin-jointed structures on the connector 37, in order to junction button component 31 and regulating part 35.In the present embodiment, this connector 37 is substantially oblong-shaped cam, and the pin-jointed structure on it comprises a circular pivoted hole 372 and the semicircle pivoted hole 371 being located at the cam top and being in communication with the outside.The medial end of two arms 313 of buckling piece 31 is articulated in this semicircle pivoted hole 371, and cooperates section 357 to be articulated in this circle pivoted hole 372 two of regulating part 35, can form above-mentioned fastener 30.Its concrete assembling process is: the medial extremity of buckling piece 31 2 arms 313 is articulated in the semicircle pivoted hole 371 of two connectors, 37 1 ends, slowly pull open two arms 353 of regulating part 35 again, its two cooperations section 357 is articulated in the circular pivoted hole 372 of two connectors 37, comes up again; So, regulating part 35 and buckling piece 31 are articulated in two connectors 37, form above-mentioned fastener 30.
Utilizing fastener 30 with radiator 20 fixedly the time, earlier the location division 311 of buckling piece 31 is placed in the groove 27 of second fins group 25 of radiator 20, and then two arms 313 of depressing buckling piece 31 move down the clasp 319 at its two ends and be interlocked with two clasps 51 of this circuit board 50, make buckling piece 31 arms 313 produce strain and tightly suppress radiator 20, thereby radiator 20 is fixed on the circuit board 50.For adjusting button is as required held the size of power, can make regulating part 35 with respect to radiator 20 horizontal movements by rotation push-and-pull regulating part 35, even the location division 351 of regulating part 35 is located in the different grooves 27 of first fins group, 23 radiating fins composition, can make regulating part 35 with respect to radiator 20 horizontal movements; The motion of regulating part 35 drives connector 37 rotations and then the location division 311 relative radiators 20 of buckling piece 31 is moved up and down, distance between the pedestal 21 of adjusting location division 311 and radiator 20, increase or reduce, thereby impel buckling piece 31 arms 313 further to strengthen or reduce strain, thereby regulate the active force of 30 pairs of radiators 20 of fastener.Meanwhile, 37 generations one and the opposite horizontal force of regulating part 35 directions of motion of 31 pairs of connectors of buckling parts, thus the location division 351 of regulating part 35 tightly is pressed on the radiating fin.In addition, behind the fastening, two arms 313 of buckling piece 31 separate with pedestal 21, and the bottom of connector 37 directly suppresses in two along portion 29, and two arms 353 of regulating part 35 are suppressed in along portion 29.
During dismounting, rotation regulating part 35 makes regulating part 35 take out from the groove 27 of radiator 20, two arms 313 of depressing buckling piece 31 again the clasp 319 at its two ends is moved down and corresponding in two clasps 51 of circuit board 50 separation, promptly finish dismounting.
Be appreciated that ground, utilizing fastener 30 with radiator 20 fixedly the time, the clasp 319 at two arms, 313 two ends of buckling piece 31 move down and corresponding two clasps 51 that are fastened on this circuit board 50 in after, buckling piece 31 arms 313 can not produce strain earlier yet; Afterwards, can regulate distance between location division 311 and the pedestal 21, thereby impel buckling piece 31 arms 313 to produce strains, thereby tightly suppress radiator 20 by adjusted part 35.
