Abstract
The present invention relates to a method for manufacturing a radiator. The present invention comprises the steps that aluminium or aluminium alloy is squeezed and molded into a radiator; the radiator is slotted with a plurality of slots; a copper metal circular disk-shaped plate body is used, and the plate body and the radiator are respectively clamped on a headstock clamping disk and a tailstock magnetic clamp so that the base bottom surfaces of the plate body and the radiator are mutually opposite; the headstock clamping disk is rotated at high speed and drives the plate body to make high-speed rotation; an oil hydraulic cylinder arranged on a work machine table is activated so that the thrust of the work machine table pushes the tailstock magnetic clamp and the radiator arranged on a tailstock to move towards the plate body until the base bottom surface of the radiator contacts the plate body; when the base bottom surface of the radiator is fused to a proper status, the headstock clamping disc of the work machine table stops rotating, and the thrust of the oil hydraulic cylinder further pushes the tailstock and the magnetic clamp so that proper pressure is maintained between the plate body and the base bottom surface of the radiator; after cooled, the plate body is tightly combined with the base bottom surface of the radiator.
Description
The present invention mainly is about a kind of manufacturing method of heat radiator, particularly simple, as to be fit to automated production manufacturing method of heat radiator about a kind of manufacture process, and its prepared radiator, structure is firm, radiating effect is good and with low cost.
Along with developing rapidly of computerized information industry, requirement to the central processing unit (CPU) arithmetic speed improves constantly, under this kind trend, the heat that central processing unit produced also increases severely with it, as if untimely heat is discharged, stability and quality to the signal transmission will be very unfavorable, discharge the heat that central processing unit produces so be necessary to set up a radiator.
The manufacture method of existing relevant radiator has a variety of, and the person is one of them as shown in Figure 1.This radiator adopts conventional aluminum extrusion forming, is extruded by the aluminum or aluminum alloy one to form, and comprises pedestal 1 and extends some fins 2 on pedestal 1.The heat that this pedestal 1 bottom surface contacts with chip 3 end faces so that chip 3 is produced conducts to fin 2, simultaneously and by big cooling surface area that fin 2 provided heat is distributed.But this type of radiator is to make in the extrusion molding mode, and the height of fin 2 will be influenced by mould and manufacture level and certain limit is arranged, even correspondingly the cooling surface area of radiator is restricted.Moreover because this radiator is made into integration by aluminum metal, the thermal conduction effect of aluminum metal is relatively poor, thereby its radiating effect and do not meet user demand now.
In view of this, industry has the radiator that adopts pedestal and fin to separate manufacturing, and it will be bent into wavy fin in addition and be incorporated on the pedestal by heat-conducting glue.Though this type of radiator can increase the integral heat sink surface area,, cause its integral heat sink effect still not meet the demand of high-power die because of the thermal resistance value that is positioned at the heat-conducting glue between pedestal and fin is bigger.
In addition, in order further to promote radiating effect, industry also has the radiator that adopts copper coin, and it is incorporated into copper coin on the radiator by heat-conducting glue or welding manner.But the copper coin of this kind radiator can't closely be bonded on the radiator, thereby the integral heat sink effect does not still meet demand.
Therefore, how providing a kind of radiator that is enough to improve aforementioned every shortcoming and meets central processing unit user demand now, is a problem extremely to be solved in fact.
The object of the present invention is to provide the manufacturing method of heat radiator that a kind of processing procedure is simple, be fit to automated production, and by its radiator that makes, structure is firm, radiating effect is good and with low cost.
The present invention reaches above-mentioned purpose by the following technical programs: this manufacturing method of heat radiator may further comprise the steps: the aluminum or aluminum alloy extrusion forming is obtained a radiator; On radiator, cut some grooves; Provide a bronze medal round metal dish type plate body, and clipping is on the headstock chuck and tailstock magnetic chuck of work board respectively with plate body and radiator, the base bottom surface that makes plate body and radiator toward each other; The chuck of high speed rotating headstock also drives plate body high speed rotating together; The oil hydraulic cylinder of activation work board, pushing away of oil hydraulic cylinder defended promote tailstock magnetic chuck and on radiator move towards plate body, base bottom surface contact plate body up to radiator, when the base bottom surface for the treatment of radiator is melted to appropriate state, the headstock chuck of work board will stop the rotation, and pushing away of oil hydraulic cylinder defended and will further be promoted tailstock and magnetic chuck, make between the base bottom surface of plate body and radiator and keep suitable pressure, after cooling, being about to plate body combines closely to the base bottom surface of radiator.
Owing to adopted technique scheme, the present invention to have advantages such as simple, the prepared heat spreader structures of manufacture process is steady, good heat dissipation effect.
In conjunction with the embodiments the present invention is further described with reference to the accompanying drawings.
Fig. 1 is the three-dimensional view of existing radiator and related chip.
Fig. 2 is the three-dimensional exploded view that utilizes the radiator that manufacturing method of heat radiator of the present invention makes.
Fig. 3 is the end view of used equipment of manufacturing method of heat radiator of the present invention and prepared radiator.
Fig. 4 is the three-dimensional view that utilizes the radiator that manufacturing method of heat radiator of the present invention makes.
Please also refer to Fig. 2 and Fig. 4, manufacturing method of heat radiator of the present invention comprise substantially extrude, profile groove, clipping, rotation and five steps of welding.At first be that the aluminum or aluminum alloy extrusion forming is obtained a radiator 30, this radiator 30 comprises the radiating fin 34 that a pedestal 32 and some row extend on pedestal 32 and each interval is arranged in parallel.Afterwards, on radiating fin 34, cut some grooves 36, to increase the cooling surface area of radiator 30.Then, provide a bronze medal round metal dish type plate body 50, and clippings are on headstock 60 chucks 62 of work board and tailstock 70 magnetic chucks 72 respectively with plate body 50 and radiator 30, pedestal 32 bottom surfaces that make plate body 50 and radiator 30 toward each other.Then, the chuck 62 of high speed rotating headstock 60 and drive plate body 50 high speed rotating together.At last, activate the oil hydraulic cylinder of workbench, make pushing away of oil hydraulic cylinder defend 80 promote tailstocks 70 magnetic chuck 72 and on radiator 30 move towards plate body 50, up to pedestal 32 bottom surfaces of radiator 30 contact plate body 50, rub pedestal 32 bottom surfaces of aluminum metal radiator 30 of copper metal plate 50 by high speed rotating, under the lower situation of aluminum metal fusing point, pedestal 32 bottom surfaces of this radiator 30 will produce fusing, and when pedestal 32 bottom surfaces for the treatment of radiator 30 are melted to appropriate state, headstock 60 chucks 62 of work board will stop the rotation, and pushing away of oil hydraulic cylinder defended 80 and will further be promoted tailstock 70 and magnetic chuck 72, make between pedestal 32 bottom surfaces of plate body 50 and radiator 30 and keep suitable pressure, after cooling, being about to plate body 50 combines closely to pedestal 32 bottom surfaces of radiator 30.
