Description

The heat abstractor combination

The utility model is about a kind of heat abstractor combination, refers in particular to a kind of heat abstractor combination easy, that button keeps steady admittedly and radiating effect is good of loading and unloading.

Along with the fast development of computer industry, the performance of computer is maked rapid progress, wherein with the fastest developing speed with central processing unit again.Fast lifting along with the central processing unit operating frequency, the heat that it produced is also increasing, for in time discharging the heat that central processing unit produced, guarantee its normal operation, usually by a fastener with a fastener of radiator on central processing unit to reach preferable radiating effect.

In the fit system of existing fastener and radiator, adopt the pressure mode that goes up mostly, radiator is placed (fan can be installed again to strengthen radiating effect in the radiator top) on the central processing unit end face, fastener is then inserted on the radiator in the default storage tank, compresses radiator and radiator is fitted tightly to the central processing unit end face by fastener.But existing this mode needs to offer the storage tank that this fastener of suitable confession is inserted on radiator, has so promptly reduced the radiating fin total quantity and the integral heat sink surface area of radiator, and then has influenced radiating effect.

The fit system of existing another kind of fastener and radiator is that fastener is installed in the radiator below, and shown in No. the 233050th, Taiwan patent announcement, its fastener is to be installed on the discoid bottom of radiator with screw-in version.But, this mode needs to be provided with respectively the screw thread of corresponding matching on the discoid bottom of fastener and radiator, processing is difficulty comparatively, and linkage editor is also comparatively cumbersome, and, between this fastener is bottom radiator is to reach with the screw thread screw-in version to combine, be difficult to the degree of depth that accurately control screws in, if the screw-in depth when screwing togather is excessive, to hold the excessive central processing unit that causes of strength because of button damages, and if the screw-in depth deficiency when screwing togather, will hold the strength deficiency because of button and cause the not good radiating effect that influences of applying situation between radiator and central processing unit.In addition, under vibrations or the environment that rocks, screw togather improper most probably cycle between this fastener and radiator bottom, cause to detain and hold the strength deficiency and do not cause applying situation between radiator and central processing unit good and influence radiating effect.

The purpose of this utility model is to provide a kind of heat abstractor combination easy, that button keeps steady admittedly and radiating effect is good of loading and unloading.

The purpose of this utility model is achieved through the following technical solutions: the combination of the utility model heat abstractor comprises a radiator, a fan and a fastener.This radiator bottom is one to be petal-like buckling parts, its periphery outwards protrudes out some key teeth, upwards form the groove of the slightly little annular of a sectional area from the buckling parts upper face center, the groove top is a disc, the top of this disc is formed with some radiating fins that are radial arrangement, and the several dissipation fins lower end outwards protrudes out a flange respectively, and has the adjacent radiating fin of minority not protrude out flange and form a breach; This fastener comprises a main part, these main part central authorities offer one and correspondingly with the buckling parts of radiator are complementary fastening hole, the periphery of this fastening hole inwardly protrudes out some key teeth, each extends first elastic arm obliquely the main part two ends, second elastic arm, some cramps are extended in this first elastic arm leading edge bending down, and a stop bit catch is extended in its leading edge central authorities bending up, second elastic arm makes progress earlier and then is bent to form a make-up arm downwards, fuse by a connecting piece between this two buttons arm end, extend an operating portion from this brace upper limb bending, and this button arm leading edge is extended second cramp down.

Owing to adopted technique scheme, that the combination of the utility model heat abstractor has is simple in structure, loading and unloading are easy, button keeps steady solid and the good advantage of radiating effect.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 4 is that the utility model heat abstractor is when being used in combination and the three-dimensional combination figure of associated component.

See also Fig. 1 to Fig. 3, the combination of the utility model heat abstractor comprises a radiator 10, a fan 30 and a fastener 40.

The bottom of this radiator 10 is buckling partss 12, this buckling parts 12 is petal-shaped, its periphery outwards protrudes out some key teeth (scheming not label), upwards form the groove 14 of the slightly little annular of a sectional area from these buckling parts 12 upper face center, the top of this groove 14 is discs 16, the top of this disc 16 is formed with the some radiating fins 18 that are radial arrangement, and the lower end of most of radiating fins 18 outwards protrudes out a flange 20 respectively, and has the adjacent radiating fin 16 of minority not protrude out flange and form a breach 22 (seeing also Fig. 1 or Fig. 3).In addition, these some radiating fins 18 in the center upper portion one common peripheral of radiator 10 around forming a cylindric alcove 24.

This fan 30 is to be installed in the alcove 24 of radiator 10.

This fastener 40 has a horizontal main part 42, the central authorities of this main part 42 offer one and correspondingly with the buckling parts 12 of radiator 10 are complementary fastening holes 44, the periphery of this fastening hole 44 inwardly protrudes out some key teeth (scheming not label), and the two ends of main part 42 are extended first elastic arm 46, second elastic arm 48 respectively obliquely.A pair of first cramp 50 is extended in the leading edge bending of this first elastic arm 46 downwards, and the bending of the leading edge of first elastic arm 46 central authorities extends upward a stop bit catch 52, the end of this stop bit catch 52 is horizontal expansion one grab 54 again, bend again after the end of this second elastic arm 48 is stretched so that more wide-angle is upward and extend a make-up arm 56 downwards, by a connecting piece 58 both are fused between these two buttons arm 56 ends, and the upper limb of this brace 58 outwards bends to main part 42 bendings earlier again and extends an operating portion 60, and the leading edge of each button arm 56 is extended one second cramp 62 more respectively downwards.Be equipped with ribs 64 around this fastening hole 44 and on the elastic arm 46,48, and offer respectively on this first cramp 50, second cramp 62 respectively with connector 80 end walls on projection 86 button hole 68 (as shown in Figure 4) of hook mutually.

See also Fig. 4 simultaneously, when assembling, earlier the buckling parts 12 of these radiator 10 bottoms is aligned the fastening hole 44 of fastener 40 main parts 42 central authorities, both key teeth are staggered mutually, so that the buckling parts 12 of radiator 10 passes the fastening hole 44 of fastener 40, at this moment, the annular groove 14 of the main part 42 fit radiators 10 of this fastener 40, its stop bit catch 52 are arranged in the breach 22 of radiator 10 radiating fins 18 lower ends; Then, rotate grab 54 hooks that this fastener 40 makes stop bit catch 52 ends on the flange 20 of these breach 22 peripheral regions, and the key tooth on the fastening hole 44 of fastener 40 and radiator 10 buckling partss 12 is to align mutually to prevent fastener 40 landings; Then the lower surface of radiator 10 lower end buckling partss 12 is fitted in the end face of central processing unit 70, and with the be fastened and connected projection 86 of device 80 of the button hole 68 of first cramp 50 of fastener 40 1 ends, the operating portion 60 of pushing fastener 40 other ends again makes the button hole 68 of second cramp 62 be fastened on the projection 86 of connector 80 other ends; At last fan 30 is mounted to the assembling of promptly finishing heat abstractor in the alcove 24 of radiator 10.
