Description
Technical field
The present invention relates to a kind of heat abstractor, refer in particular to a kind of heat abstractor that is used for cooling electronic component.
Background technology
When moving, can produce a large amount of heats such as computer cpu, north bridge chips, the contour electronic components of high power of video card, if these heats can not be left effectively, to directly cause temperature sharply to rise, and badly influence the normal operation of electronic devices and components.For this reason, needing to add a heat abstractor comes these electronic devices and components are dispelled the heat.
Traditional heat abstractor is usually by spraying or paste brand, trade mark or the other guide that mode such as a simple and easy label identifies this heat abstractor.Though this form of identification is simple, if when being used for middle and high shelves product, form is too simple, may not satisfy client's needs.Simultaneously, the label that posts also comes off easily and causes losing.
Summary of the invention
In view of this, be necessary to provide a kind of independently heat abstractor of identification piece that has.
A kind of heat abstractor, be used for electronic element radiating, it comprises a radiator, this radiator comprises base plate that a bottom surface contacts with described electronic component and the some radiating fins that extend from the end face of this base plate, two radiating fins of being separated by are provided with snapping portion, and an identification piece is undertaken on the described radiating fin end face and is interlocked with the snapping portion of described radiating fin.
Compared with prior art, heat abstractor of the present invention is placed in described radiator with an identification piece correspondence to have on the radiating fin of snapping bilge construction, and convenient disassembly is installed firmly.Simultaneously, identification piece is placed on the described radiator, can intuitively shows product informations such as trade mark, title, form is attractive in appearance.
With reference to the accompanying drawings, the invention will be further described in conjunction with the embodiments.
Description of drawings
Fig. 1 is the three-dimensional combination figure of the heat abstractor of one embodiment of the present invention.
Fig. 2 is the three-dimensional exploded view of Fig. 1.
Embodiment
See also Fig. 1, the heat abstractor of one embodiment of the present invention is used to be installed on heat-generating electronic elements such as CPU (central processing unit), the VRM (central processing unit voltage adjusting assembly) and to it and dispels the heat.This heat abstractor comprises that a radiator 10 and is placed in the identification piece 20 on the described radiator 10.
Please consult Fig. 2 simultaneously, above-mentioned radiator 10 is integrally formed by thermal conductivity good metal material such as aluminium, copper etc., comprises that a base plate 12 reaches by these base plate 12 extended some radiating fins 14.Described base plate 12 is roughly rectangular, and its bottom surface contacts with described electronic component.12 liang of diagonal angles of described base plate vertically outwards protrude out a bar shaped installation portion 16 respectively at relative short edge one side.The central authorities of each installation portion 16 all form a circular through hole 160, are used to install and fix described radiator 10.Described radiating fin 14 is extended upward by the end face of described base plate 12, and these radiating fins 14 are provided with along the horizontal space of this base plate 12.Described radiating fin 14 comprises respectively near some first radiating fins 141 of base plate 12 both sides and is positioned at some second radiating fins 142 of base plate 12 central authorities.The height of described second radiating fin 142 is progressively successively decreased by the mediad both sides of base plate 12, makes the end face of these second radiating fins 142 be arch on the whole.Be positioned at the height of the height of outermost second radiating fin 142 less than first radiating fin 141 that is adjacent.The top of described two first radiating fins 141 adjacent with described second radiating fin 142 is provided with snapping portion, is used for the described identification piece 20 of holding.In the present embodiment, the bar shaped clasp 140 that described snapping portion protrudes out respectively inwardly for the tip edge along these 2 first radiating fins 141.Simultaneously, in other embodiments, described clasp 140 is not limited to be formed at the top of described radiating fin 14, and it can be formed at other positions of radiating fin 14, and two clasps 140 also can be on the contrary to setting.
Consult Fig. 1 to Fig. 2 again, above-mentioned identification piece 20 is a rectangle elastic metallic lamellar body.Slightly upwards arching upward in the middle part of described identification piece 20, makes this identification piece 20 have certain radian on the whole, places on the end face of described second radiating fin 142 with the correspondence lid.Described identification piece 20 is formed with clasp 140 on the span on the longitudinally and described radiator 10 the spacing of 2 first radiating fins 141 is corresponding consistent.The two opposite sides edge tail of this identification piece 20 is bent upwards respectively and extends a button limit 22, with two clasps, the 140 corresponding blockings of first radiating fin 141 of described radiator 10.Simultaneously, in other embodiments, described button limit 22 is not limited to be extended upward by the side end of identification piece 22, also can extend by other positions of identification piece 22, as extending downwards, as long as described button limit 22 can the corresponding matching blocking with described 140 near terminal, close identification piece 22 middle parts or by identification piece 22 bottom surfaces.When using heat abstractor of the present invention, by modes such as punching presses, can on described identification piece 20, be formed with raise up, to the sign of forms such as lower recess or hollow out, show information such as trade mark, title with correspondence.When described identification piece 20 is installed, only need earlier button limit 22 correspondences of these identification piece 20 1 ends to be placed in the lower surface of the clasp 140 on the described radiator 10, press down the other end of identification piece 20 again, make identification piece 20 generation strains and another is detained the lower surface of another clasp 140 of limit 22 tight fasteners on radiator 10.At this moment, described identification piece 20 second radiating fin 142 that is undertaken in described radiator 10 is on the end face of arch.When dismantling this identification piece 20, only need the above-mentioned flow process of reverse operating to get final product.
In sum, heat abstractor of the present invention is placed in described radiator 10 with an identification piece 20 correspondences to have on the radiating fin 14 of clasp 140 structures, and convenient disassembly is installed firmly.Simultaneously, identification piece 20 is placed on the described radiator 10, can intuitively shows product informations such as trade mark, title, form is attractive in appearance.
