Abstract

A heat sink is fixed on a motherboard to assist the heat dissipation of the CPU on the motherboard, which primarily comprises a heating body, a base, a flexible fastener, a fan and a radiator hood. The heating body is formed from the sequent stacking of a plurality of dissipating fins, in which the above is opened with two through holes running through each dissipating fin. The inside of the through holes are respectively accommodated with a rod. Two fastening areas are respectively formed on two opposite sides of the base. Each fastening area comprises an interpenetrated groove hole, a containing space extended and opened from the groove hole, as well as a fastening part. The flexible fastener is formed from the one body bending of a metal wire material, which has a junction disposed on the ends of two rods. Both ends of the junction respectively extended downward are in repeatedly bending to be in the formation of an elastomer. After continuously extended downward for a certain length, the end of the elastomer is bent to be in the formation of a clasp in which the heating body can be fixed on the base, coupled with the fastening area of the base.

Description

Heat abstractor

[technical field]

The utility model is about a kind of heat abstractor, refers in particular to a kind of good heat dissipation effect, assembles convenient and detains the solid heat abstractor that keeps steady.

[background technology]

Along with the fast development of electronics and information industry, the operating frequency of electronic building brick and the speed of service are also in continuous lifting.But high-frequency high-speed will make the heat of electronic building brick generation more and more, and the performance and running stability of electronic building brick in serious threat, in order to ensure the normal operation of electronic building brick energy, must in time discharge the heat that electronic building brick produced.For this reason, the method that industry adopts usually is to install the heat abstractor with great heat radiation effect on electronic building brick additional, with timely discharge heat.

Traditional heat abstractor, by the thin heat radiation body heat radiation that some radiating fins are formed, this radiator can be fixed on the pedestal of heat abstractor by modes such as epoxy resin bonding, soldering or interference are pressed into.But all there is shortcoming in above-mentioned combination, as the epoxy resin bonding mode, because of the adhesive of adhesive effect has been arranged in the thermal conducting agent, so heat-conducting effect is relatively poor.And the soldering combination easily forms higher thermal resistance on the one hand in the junction; On the other hand, this combination processing cost is higher and not easy to assemble.In addition, interference is pressed into mode, need just can finish assembling by extra tool, thus exist packaging efficiency low, the shortcoming that human cost is high, and when assembly cooperated unstability, the air gap can appear, influence radiating effect.

[summary of the invention]

The purpose of this utility model is to provide a kind of good heat dissipation effect, assembling is convenient and detain the solid heat abstractor that keeps steady.

The purpose of this utility model is achieved through the following technical solutions: the utility model heat abstractor, be fixed on the motherboard and assist central processing unit heat radiation on it, mainly comprise a radiator, a pedestal, two elastic fasteners, a fan and a heat dissipating housing.This radiator is formed by stacking piecewise by some radiating fins, offers the two through hole that runs through each radiating fin on it, the ccontaining body of rod of difference in the through hole.The relative dual-side of this pedestal respectively forms two buckle districts, and each buckle district comprises that a slotted eye that connects, extends an accommodation space and a clamping part of offering from this slotted eye.This elastic fastener is formed by the bending of metal wire rod one, has a connecting portion that places two body of rod ends, the two ends of this connecting portion extension downwards respectively also are bent to form an elastomer repeatedly, this elastomeric terminal continuation is bent to form a fastener portion behind the extension certain-length downwards, and cooperates the buckle district of pedestal that radiator is fixed on the pedestal.

The advantage of the utility model heat abstractor is: the utility model heat abstractor adopts a kind of elastic fastener that is formed by the bending of metal wire rod one to come combination heat dissipation body and pedestal, this elastic fastener is drawn materials easily and is simple in structure, so convenient manufacturing, simultaneously, use this elastic fastener combination heat dissipation body and pedestal, can not only realize assembling convenient and button keep steady solid purpose and good heat dissipation effect.

In conjunction with example the utility model is further described with reference to the accompanying drawings.

[embodiment]

See also Fig. 1, the utility model heat abstractor can be fixed on motherboard (no icon) and go up and assist the central processing unit (no icon) on it to dispel the heat, and it mainly comprises a radiator 10, a pedestal 30, two elastic fasteners 50, a heat dissipating housing 60 and a fan 70.Wherein, this radiator 10 is formed by stacking piecewise by some radiating fins 12, offer two through holes 14 that run through each radiating fin 12 on this radiator 10, each through hole 14 can wear for a body of rod 20, the two ends of each body of rod 20 form a backstop 22 respectively, can a sheathed baffle ring 26 on each backstop 22.These pedestal 30 relative sides form two buckle districts 32 respectively, and each buckle district 32 comprises that a slotted eye that connects 34, extends an accommodation space 36 and a clamping part 37 of offering from this slotted eye 34.Four jiaos of places of this pedestal 30 respectively are provided with a pilot hole 38, place for the screw rod 40 that is arranged with a spring 42, and in addition, this pedestal 30 respectively is provided with two screws 44 on the side of offering buckle district 32.

This elastic fastener 50 is formed by the bending of metal wire rod one, it has a horizontal connecting portion 52 that is hung on these two bodies of rod, 20 ends, the two ends of this connecting portion 52 extension downwards respectively also are bent to form an elastomer 54 repeatedly, the end of this elastomer 54 outwards is bent to form a fastener portion 58 after continuing to extend certain-length downwards, matches and radiator 10 is fixed on the pedestal 30 with the clamping part 37 with pedestal 30 buckle districts 32.

This heat dissipating housing 60 has a roof 62, these roof 62 relative both sides extend to form two side 64 respectively downward vertically, the lower edge of each sidewall 64 is respectively equipped with two screws 65, can screw togather and this heat dissipating housing 60 is fixed on this pedestal 30 by the screw 44 of screw 66 with pedestal 30, one lateral margin of each sidewall 64 all bends inwards and forms a kink 67, and respectively offers a screw 68 at the two ends up and down of each kink 67.And this roof 62 forms an occlusion part 69 at a side horizontal-extending of these two side 64 kinks 67.
