Description
Technical field
The invention belongs to semi-conductor electronic device heat dissipation technology field, particularly a kind of rib line formula Radiator and its preparation method.
Technical background
As everyone knows, semiconductor electronic technology develop rapidly now, size is little, operating frequency or power are but in continuous increase, it is obvious that large temperature rise becomes suddenly, for make its better, more stable, long-life work operation, the scientific and reasonable heat dissipation equipment of design configurations is most important, such as computer CPU chip, video card chip etc., particularly develops semiconductor solid illuminating lamp chip like a raging fire now, and heat radiation is still remarkable, its more than 80% electric energy conversion is heat, 2 ℃ of the every risings of temperature, its life-span reduces 10%, solves its heat radiation and is imminent.
Heat transfer and heat dissipation technology have developed last 100 years, an insider or generation generation is inheriting ancestors' family estate, adopt traditional project organization and manufacture method, although can solve reluctantly heat dissipation problem,, radiator product is heavy, production technology is many, must cause more than waste of material and high price, this runs counter to the energy saving and environment friendly and economizing type industrial development thinking of praising highly energetically and advocating now, and light weight, low cost, high performance heat dissipation equipment are by the pet that is Times ' Demand.
The rib line formula radiator that the object of the invention is to aim to provide a kind of new construction, is enough to overcome above-mentioned technical problem.
In order to achieve the above object, technical scheme of the present invention is: a kind of rib line formula radiator, it includes a fixture and one or more rib line, described in each, rib line comprises a rib body and at least one rib pin, described rib body extends described rib pin, described in each, the described rib pin of rib line is fixed on described fixture, and the described rib body of all described rib lines is arranged to predetermined pattern, for heat radiation; Wherein, after the described rib body of described rib line partly scatters, reverse molding cup-shaped structure.
The described rib pin of a plurality of described rib lines is fixed on described fixture, and the described rib body of a plurality of described rib lines is round described fixture so that described fixture is arranged on described rib body inside, and described rib body arranges radially centered by described fixture.
Described rib line adopts aluminium matter or copper or copper aluminum composite material to make, and described in each, cross section of rib line is star or circle.
The mean gap of adjacent described rib pin is less than 15mm, and the mean gap of the described rib body of adjacent described rib line is greater than 2mm, is less than 30mm, and described in each, the sectional area of rib line is greater than 2mm2, is less than 20mm2.
Count the total sectional area of many ribs foot face, by the thermal conductance of heat-radiating semiconductor electronic devices and components, gone out 1 times to 2 times of heat transfer area.
Described fixture it adopt aluminium or copper or copper aluminum composite material to make.
Described fixture is shroud ring cover.
Described fixture is heat conduction fixed head, and its thickness is greater than 2mm, is less than 20mm;
Another object of the present invention aims to provide a kind of method of manufacturing above-mentioned rib line formula radiator.
For achieving the above object, the present invention adopts following technical scheme:
Adopt the stretching technique of cutting off of wire rod to make, or adopt metal light wall pipe to cut the step that forms one or more rib line rib lines;
The rib pin section of described rib line is close to into a bundle, puts shroud ring cover outward, and adopt mould to tighten the step that technique tightens shroud ring cover;
Adopt turning processing heat radiator heat transfer contact face, to all rib foot faces and the neat bright and clean step of shroud ring cover end face;
Adopt circular cone punch die by the scatter step of a wide-angle of the rib body punching press of rib line;
The step that adopts dull and stereotyped mould that the rib body punching press of rib line is smashed
Adopt mould the rib body of rib line oppositely to be struck out to the step of glass type.
Passable, the rib pin section of described rib line is close to into a bundle, put shroud ring cover outward, and adopt mould to tighten the step that technique tightens shroud ring cover, optionally realize by the following method:
Described rib line and described heat conduction fixed head chemical nickel plating on surface are processed, the described rib pin of rib line described in each is inserted in the location hole of described heat conduction fixed head, then adopt soldering method to be welded and fixed; Or
The described rib pin of a plurality of described rib lines is close to into a bundle, and the above shroud ring cover of overcoat, adopts mould to tighten technique, and described shroud ring cover is tightened, and then chemical nickel plating on surface is processed, then by the gap of the lock ring rib foot face of shroud ring cover described in soldering process filling.
Preferably, after the described rib body of described rib line is partly scattered, reverse molding cup-shaped structure.
Adopt the fine aluminium of same weight, the cold forging rib pillar of the equal surface area of making and rib-type integrative-structure (alleged one, rib post or fin and the heat-conducting plate structure that is formed in one) radiator, at same limit test environment, do same power thermal testing, result is that rib pillar integrative-structure radiator heat-dissipation effect is better simultaneously.Analysis draws: one, the rib post of rib pillar integrative-structure radiator and the handing-over heat transfer area of heat-conducting plate are larger; Two, rib pillar integrative-structure radiator is better compared with rib-type integrative-structure radiator permeability.Again by the outwards bending from level to level of close foot of every root post of rib pillar integrative-structure radiator, the average headway that increases rib intercolumniation, average headway roughly increases 2 times, and radiator height dimension reduces, lateral dimension has increased, record radiating effect before state improved 25%.Analysis draws, the heat dispersion of radiator is relevant with the convection transfer rate of rib post or fin and surrounding air, and cooling fin post or the rib structure of radiator design more penetratingly, and cross-ventilation heat exchange coefficient is higher.Testing described sample is all to adopt fine aluminium cold-forging technique to make, cold-forging technique is first with plate material, to be washed into cake blank material, each part just has four right angle material wastes, blank material is put into cold forging press again and is forged into semi-finished product radiator, adopt again Vehicle Processing operation, there is again turning waste, with regard to luminescent material waste rate, just reach 40%.If in order to improve the heat dispersion of cold forging rib pillar integrative-structure radiator 25%, also must be as making experiment exemplar, increase is by the operation of the several rows of bending of rib post, this procedure is not easy again to design tool and adopts mechanically actuated operation to come single stepping to complete, so time-consuming, the expense of increase is high.In sum, the present invention adopts metal wire rod to carry out the rib post of alternate design cold forging rib pillar integrative-structure radiator, so be called rib line formula in the present invention, the heat conduction fixedly in plate hole that is arranged on mesh plate structure is inserted a plurality of rib line rib foots in employing, adopt again welding method to fix and connect or bundle a plurality of rib line rib pin sections with shroud ring cover, finally adopt turning or grinding to make whole rib foot faces neatly bright and clean.
