Description

The heat abstractor of chip

Technical field

The utility model relates to a kind of heat abstractor of chip.

Background technology

Under China's computing machine science and technology industry is constantly flourish, its relevant spare part is constantly research and development improvement also, little of a simple screw, big to complicated high-power die, the relevant common purpose of dealer is in order to improve product quality invariably, and reduce production costs and struggle, to improve our competitive power in international community.As far as our knowledge goes, most important core is no more than central processor CPU in main frame, because the speed of CPU high power handling data, let us is more and more convenient in the use, but the chip calculation process speed arround it is also and then accelerated relatively, also too quick because of the motion of its internal electron, make the temperature of each chip body also along with hot fast, and last result is exactly the destiny of burning.

For making the heat radiation of CPU and other chip surface evenly continue to maintain normal temperature work, on CPU and other chip surface, a heating radiator can be set usually, and be coated with thermal grease in order to the cementation heating radiator at CPU and other chip end face.

But, this existing heating radiator fixed form, though the effect that has heat radiation and install fast, but when chip moved, the high temperature of itself just was enough to make thermal grease to be reduced to sticky shape once again, makes heating radiator can float on the chip, and thermal grease is through being sticky shape by solidifying the shape thermalization repeatedly, again by sticky shape cold turn to solidify shape after, its adhesion will reduce gradually, causes the heat sinking function of heating radiator to bring into play fully indirectly.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of heat abstractor that is easy to install and remove and locate firm chip.

For reaching above-mentioned purpose, the utility model is achieved in that a kind of heat abstractor of chip, is by heating radiator, fixture and is preset in that a plurality of hook rings on the circuit board constitute around the chip, and this heating radiator is provided with a plurality of grooves that colludes; This fixture is bent continuously by two elastic wires and forms, its centre is for the extension and have a framework, can supply extension and the firm hook of framework colluding in the groove thereof in heating radiator, each bending extension one of tilting has the stretch section that colludes end and the two ends, extension are respectively to both sides, and make the symmetrical respectively elasticity of each stretch section be active in the heating radiator outside, and the corresponding stretch section angle of homonymy is less than 180 degree.

This colludes groove and comprises that one pair is colluded groove and two road lists collude groove, this heating radiator stands on a base and is provided with a plurality of spaced fins, and two row's fins have been horizontally set with the two rows overhead kick in relative side bottom in the middle of it, collude groove and form above-mentioned pair, in addition, adjacent to two fins that collude the groove and arranged on left and right sides, also be provided with row's overhead kick, at two above-mentioned grooves that singly collude that each side form one that collude groove in its lateral surface bottom transverse.

This fixture by two continuously the elastic wires that merge of symmetry bending and symmetry constitute, be provided with the extension therebetween and be bent into the spill frame, after two extensions merge, just form a rectangular frame, extension and framework firmly hook in heating radiator.

In other words, the heat abstractor of chip of the present utility model is made of heating radiator and fixture, and it is applied to a kind of circuit board that is preset with a plurality of hook rings around chip; Wherein, be provided with a plurality of grooves that collude in this heating radiator, can be snapped in the framework that colludes in the groove, and be respectively equipped with one in its both sides and have and collude end and angle less than 180 stretch section and be provided with one in the middle of the fixture, and make its stretch section respectively elasticity be active in the heating radiator outside; When heating radiator is mounted on the chip, can make and respectively collude default clasp on the corresponding hook circuit board of end by the stretch section that presses down fixture, heating radiator is easy to install and remove and the effect of strong fix on chip but reach.

The utility model has the advantages that:

1. be subjected to compressing of fixture extension owing to heating radiator of the present utility model, and its bottom surface can be fitted tightly with chip surface, therefore, can reach the effect of heating radiator strong fix.

2. the low cost of manufacture of this fixture, and assembling is quick, helps to save every cost.
