Abstract
The production method of radiator is characterized by that it mainly used wax or low-temp. metal material or petroleum-chemical raw material as raw material, and adopts the following steps: utilizing mould to prepare base material with radiator form to be made; coating the surface of base material with a layer of metal coating layer with proper thickness; respectively at least drilling more than one column pits on two sides of embryonic radiator coated with metal layer, moving said embryonic radiator into high-temp. centrifugal machine, melting and completely removing base material so as to obtain the hollow shell-type radiator with metal coated layer, then soaking and cleaning in bath with chemicals.
Description
Technical field
The present invention is a kind of method for making of radiator element, refers in particular to the method for making of a kind of integrated " hollow tubular " radiator element.
Background technology
The traditional heat-dissipating sheet is to make with the higher metallic substance of heat-conduction coefficient, and for example copper, silver or aluminium are considered from manufacturing technology, weight and material cost, and it is in the majority generally all to adopt hydronalium to make.But, because be subject to the making factor of metal, under certain volume, can't obtain bigger heat transfer area, to improve heat radiation, real is the biggest obstacle of aluminum thermal fin.
In the recent period, it is raw material in order to try to achieve the preferable radiator element product of thermal diffusivity, to use copper coin instead that the dealer is arranged, and by striking out the unit radiator element of the same specification of most sheets earlier, a slice, a slice ground spiral-lock link and be assembled into radiator element in regular turn again, and its major defect is:
The radiator element of this multi-disc coupled, in order to obtain higher heat-conduction coefficient, its tolerance range needs very high, and also solid welding is installed on the base plate separately, therefore, and when making, very consuming time taking a lot of work, its tolerance range is subject to assembly working personnel's influence, and can't grasp fully really, makes the cost of manufacture of product and fraction defective all higher.
Summary of the invention
Main purpose of the present invention provides a kind of method for making of radiator element, is set as integrated hollow shell mould by its radiator element, overcomes the drawback of prior art, reaches the purpose of simple and easy, in light weight, the bigger heat transfer area of processing procedure.
Second purpose of the present invention provides a kind of method for making of radiator element, is set as hollow tubular, column or flaky hollow shell mould by its radiator element, reaches external form and makes most purposes that change of planting.
The 3rd purpose of the present invention provides a kind of method for making of radiator element, is set as hollow tubular, column or flaky hollow shell mould by its radiator element, except that can directly using as radiator element, and can import cooling fluid, reaches the purpose of promoting radiating effect.
The object of the present invention is achieved like this: a kind of method for making of radiator element is characterized in that: it comprises the steps:
(1) base material is made: be to be raw material with wax or low-temperature metal material or petrochemical material, be molded as the fin shape of drawing up and doing by mould;
(2) surface-coated: as to be in the coating metal layer of surface-coated one deck suitable thickness of base material;
(3) base material removes: be the posthole that is drilled with at least respectively in the both sides of the blank radiator element of the coating of coated metal more than, move in the high temperature whizzer again, carry out melting and deviate from base material fully, form the hollow shell mould radiator element that keeps coating;
(4) clean: be hollow shell mould radiator element to be moved to soak in the groove that fills chemical agent and cleaning, clean through clear water again, manufacture radiator element finished product of the present invention.
This low-temperature metal material is selected from bismuth, tin or antimony.This petrochemical material is selected from plastic cement or synthetic resins.This surface-coated method is to be selected from electric or chemical deposition or vacuum vapour deposition or cathode sputtering method.This coating metal layer is selected from copper, silver or aluminium.Mill more than one side of this radiator element finished product and remove processing, with the radiator element of the biplate unit radiator element that forms an opening.The moulding of this radiator element finished product is shaped as various required moulding shapes.The unit radiator element of this radiator element be shaped as hollow sheet, column or tubulose.
Further specify below in conjunction with preferred embodiment and accompanying drawing.

Embodiment
Consult shown in Figure 1ly, the method for making of radiator element of the present invention comprises: base material makes, surface-coated, base material removes, clean or reprocess, wherein:
Consult Fig. 2-shown in Figure 3, at first, the making of base material 1 is to be raw material with wax or low-temperature metal material (as bismuth, tin or antimony etc.) or petrochemical material (as plastic cement or synthetic resins etc.), is molded as the fin shape of drawing up and doing by mould, and for example figure is depicted as a kind of grid, frame type radiator element;
Consult Fig. 4-shown in Figure 5, secondly, surface-coated is in the surface of base material 1, by electric or chemical deposition or vacuum vapour deposition or cathode sputtering method, and metal (copper, silver or the aluminium) coating 21 of lining one deck suitable thickness;
Then, it is the posthole 22 that is drilled with at least respectively in the both sides of the blank radiator element 2 of coated metal coating 21 more than that base material removes, move to again in the high temperature whizzer (omitting among the figure) that can melt base material 1, carry out melting and deviate from base material 1 fully, form hollow shell mould radiator element 2a as the reservation coating 21 of Fig. 6-shown in Figure 7;
At last, cleaning is that hollow shell mould radiator element 2a is moved in the groove that fills chemical agent (removing dilute hydrochloric acid or dilute sulphuric acid or scavenging solution etc.), soaks and cleans, and cleans through clear water again, manufactures radiator element finished product of the present invention, as Fig. 6-shown in Figure 7.
Consult shown in Figure 8.Before manufacturing radiator element finished product of the present invention, can will mill more than the one side remove processing, with the biplate unit radiator element 23a that forms an opening and the radiator element 2b of 23b, its better heat-radiation effect.
