Description
[technical field]
The relevant a kind of faster for radiating device of the present invention, particularly a kind of easy accessibility and fastening are easy to faster for radiating device.
[background technology]
Along with improving constantly of electronic component integrated level, the heat dissipation problem of electronic component is also more and more outstanding, with the computer motherboard is example, the all integrated mostly big caloric value electronic components of high frequency such as central processing unit, north bridge, south bridge, multimedia process chip on the current mainboard, when temperature is too high, can influence the performance and the stability of these electronic components, will not cause system crash even burn mainboard if do not deal carefully with heat dissipation problem.For the working temperature that makes these high frequency heat dissipation elements is in the normal range (NR), industry generally adopts auxiliary its heat radiation of mode at element surface installing radiator, simultaneously, for radiator is firmly contacted fully with element surface, need radiator be pressed in electronical elements surface by a fastener usually.
Adopt after the fastener, can make the fixing efficient and convenient of radiator, also can make to engage closely between radiator and the electronic component, and the pressure that electronical elements surface is subjected to is even.Current existing various fasteners are used to the fixing of heat abstractor, as Fig. 1, shown in Figure 2, this heat radiation fastener comprises two fasteners 10, this two fastener 10 is symmetrically fixed on the radiator 15, this radiator 15 places heat dissipation element (not shown) surface, this fastener 10 has certain toughness, fastener 10 middle parts convex to form first holding section 11, these projection both sides stretch out and form second holding section 12 of one group of symmetry, corresponding with this first holding section 11 and second holding section 12, these radiator 15 surfaces are provided with first draw-in groove 16 and second draw-in groove 17, respectively in order to engage this first holding section 11 and second holding section 12, second holding section 12 of this group symmetry is bent to form a kink 13 after extending radiator 15 outsides, these kink 13 ends are provided with a grab 14; So, on radiator 15 during fastener for installing 10, at first with first holding section 11 and second holding section, 12 corresponding first draw-in groove 16 of difference and second draw-in grooves 17, as seen from the figure, first draw-in groove 16 is relative with second draw-in groove, 17 opening directions, so need earlier one in first holding section 11 or second holding section 12 to be pressed into earlier in the corresponding draw-in groove, being pressed into another one afterwards again can be fixed in fastener on the radiator; The residing circuit board of radiating electronic element (not shown) surface is provided with four hole clippings with these four grab 14 opposite positions, so, grab 14 depressed respectively make it to snap in the corresponding hole clipping, can make this radiator 15 closely and equably be affixed on electronical elements surface.
Yet the fastener of the said structure process that fastener is pressed into when assembling is cumbersome, and the dismounting fastener is also inconvenient; Be easy to damage is caused at the draw-in groove position on the radiator in the process of fastener installation and removal, thereby cause the bad order of radiator; And this kind fastener is unfavorable for two fasteners are buckled on the product simultaneously, because draw-in groove part can't elastic yield when fastening, is easy to cause product bad.
[summary of the invention]
In view of above problem, the invention provides a kind of easy accessibility and fasten easy faster for radiating device, be difficult to and cause the bad defective of product to overcome existing fastener dismounting inconvenience and to fasten.
For achieving the above object, the invention provides a kind of faster for radiating device, be used for radiator is fixed in the heat dissipation element surface, this fastener comprises the fastener of at least two symmetries, and this fastener comprises: a body, and this body is L-shaped; One holding section, this holding section are positioned at an end of body, and this holding section is hook solid and to body direction bending, this holding section has certain elasticity, and this holding section end is bent to form a barb once more, and this barb overbending direction is opposite with this holding section; One buckling parts, this buckling parts is positioned at the other end of body, and this buckling parts is a grab.And spreader surface is provided with some engaging bodies, this engaging body bilateral symmetry and be provided with a strip-shaped clamp groove separately, this draw-in groove is corresponding with the holding section, depressing this barb can push this holding section in this draw-in groove, continue to be pushed into this crotch and eject and fastener can be fixed on the radiator between the body, even and buckling parts is buckled in the set hole clipping of heat dissipation element apparatus surface of living in this heat abstractor is close to the heat dissipation element surface in two engagings.
The fastener of two symmetries so can make the heat dissipation element surface stressed evenly with respect to this radiator symmetry; For the bigger electronic component of heat dissipation capacity, for being had more closely with electronical elements surface, radiator contacts, can increase one or several fasteners, and these fasteners are uniformly distributed in around the radiator.
Compared with prior art, faster for radiating device of the present invention only needs one to press and fastener can be fixed on the radiator gently, also only needs one to press and fastener can be pulled out during dismounting, and so dismounting is very convenient and be difficult for causing the damage of radiator and fastener; The fastener that faster for radiating device of the present invention adopted is one-sided fastener, and promptly each fastener has only a buckling parts, so can adjust the number of fastener according to heat dissipation element and heat dissipation capacity size, thus conservation and cost; And fixedly during heat abstractor, also can depress two fasteners simultaneously and can not damage radiator, can increase yield of products, thereby enhance productivity, have good popularization value.
