Abstract
A production method of high-density radiator includes the following steps: firstly, providing a mould with specially-designed shape, pressing the aluminium block heated to a proper temperature into the said mould, cutting according to a certain length to obtain its intermediate body including a curved base seat, several radiating fins which are made into upward radiating and extending form from said base seat and grooves between every two fins; and secondly, flattening the curved base seat so as to obtain the invented radiator.
Description
The present invention refers to a kind of radiating fin density that can improve radiator especially about a kind of manufacture of high-density radiator, and the manufacture of high-density radiator that radiating effect is improved.
Along with the fast development of information industry and the expansion of range of application thereof, also more and more high to the requirement of associated electronic components processing speed.Be accompanied by the raising of the speed of service, the heat that produces also rolls up relatively, is stability and the quality that guarantees to use, and must in time this heat be discharged.
Existing be used for assisting electronic component to discharge the relevant radiator of heat, can be with reference to United States Patent (USP) the 5th, 621,615 and 5,630, cases such as No. 469.The structure of this type of radiator is as shown in Figure 1: pedestal 3 end faces of radiator 1 are convex to be provided with some radiating fins that are arranged in parallel with each other 5, and abutting in electronic component by pedestal 3 bottom surfaces derives heat, through radiating fin 5 heat is shed again.This type of radiator 1 is extrusion molding at a certain temperature (Extrusion) earlier, again through cutting and concerned process steps such as subsequent treatment obtains.Owing to need consider the intensity of mould during extrusion molding and avoid producing the fracture situation at the stress maximum, so related die must be designed to suitable shape, and causes the groove 7 of 5 of radiating fins to have sizable width and for wide at the top and narrow at the bottom skewed.Not only radiating fin 5 density are too small for this kind radiator 1, and it is wide at the top and narrow at the bottom because of groove 7, the space phase shape of (being groove 7 belows) is less more nearby at distance thermal source (being electronic component), and can't flow for more air, therefore is difficult to realistic user demand.
The object of the present invention is to provide a kind of manufacture of high-density radiator,, and radiating effect is promoted with the radiating fin density of raising radiator.
Manufacture of high-density radiator of the present invention is reached above-mentioned purpose by following means, this method may further comprise the steps: first, one mould with given shape is provided, clamp-on the aluminium block that is heated to proper temperature in this mould and fixed length cuts the back and obtains an intermediate, this intermediate comprises an arcuate base, somely upwards is the radiating fin of radial extension and is positioned at groove between radiating fin from the pedestal one; The second, the arcuate base of intermediate is flattened and obtains radiator, this moment, these some radiating fins were arranged in parallel with each other, and the width up and down of groove is all identical.
Prior art is relatively used the resulting radiator of manufacture of high-density radiator of the present invention can improve radiating fin density and is made the radiating effect increase.
The accompanying drawing simple declaration:
Fig. 1 is the three-dimensional view of existing radiator.
Fig. 2 is the three-dimensional view that utilizes the intermediate of manufacture of high-density radiator gained of the present invention.
Fig. 3 is the three-dimensional view that utilizes the radiator of manufacture of high-density radiator gained of the present invention.
The present invention is further illustrated below in conjunction with embodiment and with reference to accompanying drawing:
Please consult Fig. 2 and Fig. 3 together, manufacture of high-density radiator of the present invention is divided into two steps.First step is: a mould with given shape (figure does not show) is provided, clamp-ons the aluminium block that is heated to proper temperature in this mould and fixed length cuts the back and obtains an intermediate 10.This intermediate 10 comprises an arcuate base 12, somely upwards is the radiating fin 14 of radial extension and is positioned at the groove 16 of 14 of radiating fins from pedestal 12 one.The top of this radiating fin 14 has identical width with the bottom, and is formed with " V " font grooving 18 that communicates with groove 16 on the end face of pedestal 12.
Second step of manufacture of high-density radiator of the present invention is: arcuate base 12 pressings of intermediate 10 are obtained radiator 20, this moment, these some radiating fins 14 were arranged in parallel with each other, and the width up and down of groove 16 is all identical, and this grooving 18 then driving fit becomes seam.
If promote the integral heat sink effect of radiator 20, can further carry out polishing and increase flatness radiator 20 pedestals 12 bottom surfaces, perhaps radiator 20 integral body are carried out anode and handle.
Because during extrusion molding, the maximum stress place of mould is positioned at the section that forms groove 16 tops, so the radiating fin 14 of intermediate 10 of the present invention is designed to radial extension, having bigger width can use for mould on groove 16 tops of intermediate 10, produces the fracture situation with the maximum stress place that avoids mould.Moreover, because radiator 20 of the present invention has the identical groove 16 of width up and down, can flow for air so have enough spaces in the nearer position of distance thermal source.
