Description

The radiator manufacture craft
[technical field]
The invention relates to a kind of radiator manufacture craft, particularly relevant for the manufacture craft of a kind of magnesium alloy and copper alloy combined radiator.
[background technology]
The effect of heat radiation concerns service life of electronic product, early stage radiator all is made with aluminium extruded type, its heat absorption is very limited with the effect of heat radiation, but develop not to be inconsistent demand gradually with the progressive of epoch, industry is actively to develop to meet metal radiator for this reason, the multiple on the market existing combined heat radiating member of elder generation, its outward appearance appearance is perhaps different separately, but the radiator that adopts up to present its inside is mostly with aluminium, its heat conduction then all is to select for use copper to make, main is good heat carrier because of the copper metal, it is fast that the thermal diffusivity of aluminium is compared copper again, but in fact, the radiating effect that its product really can produce, it also is not the most desirable reaching electromagnetic wave shielding.So, the people in the industry compares with aluminium alloy by great deal of experiment data proof magnesium alloy, and to have strength/weight ratio good, rigidity is good, shock-resistant, recyclable, wear-resisting, advantages such as electromagnetic wave shielding is good, so industry begins to attempt replacing aluminium alloy with magnesium alloy, existing manufacture craft is: copper is engaged it with the forging mode with aluminium or magnesium, but its processing technology cost height, its faying face is easy to be out of shape in the process of roll extrusion, with reference to shown in Figure 1, the processing schematic diagram that it is made for existing roll extrusion, mould 3 is easy to radiating surface 1 in the process of roll extrusion as figure shows, contact-making surface 2 crimps, thereby need extra operation to handle, existing in addition forging mode is limited to when making radiator very much, only be suitable for the heat spreader structures design (plane combines with the plane) of 2D, such structural design has also influenced the effect of heat radiation, finally also can influence the appearance of product.
In view of this, the present invention proposes a kind of radiator manufacture craft, and its processing procedure and technology are simple when making that by this radiator manufacture craft magnesium alloy combines with copper alloy, the production height, cost is low, and can make the radiator of arbitrary shape, has also realized good thermal diffusivity simultaneously.
[summary of the invention]
The purpose of this invention is to provide a kind of radiator manufacture craft, simple to solve above-mentioned the deficiencies in the prior art with the realization manufacture craft, the production height, cost is low, and can make the radiator of arbitrary shape.
According to purpose of the present invention, a kind of radiator manufacture craft is proposed, it is applied to make a radiator, and the method step of this technology is as follows:
Produce a solid copper alloy base material;
With above-mentioned solid copper alloy base material high temperature heating, heating-up temperature is 200 ℃~600 ℃;
Copper alloy base material after the heating is placed required mould;
The mode that penetrates with die casting is injected the magnesium alloy of fusion in the above-mentioned mould and is made both combinations by the HTHP mode.
Preferably, above-mentioned solid copper alloy is fine copper, red metal, bronze or brass.
Preferably, this technology also comprises: with after magnesium alloy combines, carry out surface treatment at copper alloy.
Preferably, above-mentioned surface treatment is for changing into processing.
Compared to prior art, radiator manufacture craft of the present invention makes that its processing procedure and technology were simple when magnesium alloy combined with copper alloy, and magnesium alloy and copper are in conjunction with reliable, the production height, cost is low, and can make the radiator of arbitrary shape, has also realized good thermal diffusivity simultaneously.

Fig. 2 illustrates the flow chart of steps of composite heat radiating metal preparation method of the present invention.
[specific embodiment]
As shown in Figure 2, a kind of radiator manufacture craft, it is applied to make a radiator in present embodiment, and the method step of this technology is as follows:
Step 100: the solid copper alloy base material of producing a required arbitrary shape, this copper alloy base material is preferably fine copper or red metal in present embodiment, also can be bronze or brass in addition, choose the required material of base material according to the actual needs, wherein, when making base material, can produce the base material (2D, 3D shape all can) of arbitrary shape according to the needs of made product, to reach best radiating effect;
Step 200: above-mentioned solid copper alloy base material is inserted high temperature furnace heating, and its heating-up temperature is 200 ℃~600 ℃, makes the copper alloy base material reach certain temperature, so that can reach one well in conjunction with effect following when combining with magnesium alloy;
Step 300: the copper alloy base material of heating is inserted in the mould and located, fixture in the mould is fixed this copper alloy base material, at this moment, with the die casting shoot mode magnesium alloy of fusion is injected and to be made both combinations in the above-mentioned mould, this die casting shoot mode is indoor for the liquid magnesium alloy of fusion being inserted pressure, in the above-mentioned mould of high speed filling, and make alloy liquid under high pressure, solidify the formation foundry goods, in die casting ejaculation process, choose suitable cold according to the radiator difference of required making, the hot cell machine, it is smaller to make volume, the radiator that appearance requirement is higher, when die casting, can select a hot cell machine for use, its mold temperature is 180 ℃-240 ℃, material pipe temperature is 630 ℃-650 ℃, material temperature is 630 ℃-660 ℃, firing rate is 2-3.5m/s, casting pressure be 25mpa+/-5mpa, dwell time is 0.8-2s, as make radiator of LED lamp etc., and it is big to make volume, internal structure stronger radiator, when die casting, can select cold house's machine for use, its mold temperature is 180 ℃-240 ℃, material pipe temperature is 150 ℃-240 ℃, material temperature is 680 ℃-700 ℃, firing rate is 2.8-5m/s, casting pressure be 50mpa+/-10mpa, dwell time is 4-8s, above-mentioned die casting is finished, and obtains the radiator workpiece of moulding after the cooling;
In present embodiment; preferably also comprise step 400: the workpiece after the above-mentioned moulding is carried out surface treatment; this surface treatment is and changes into processing; this changes into and is treated to: use magnesium alloy chemical synthesis treatment liquid; strengthen the diaphragm of corrosion stability of magnesium alloy with formation one deck, thereby prevent that magnesium alloy from producing corrosion in atmosphere.
Radiator manufacture craft of the present invention can be made the radiator of arbitrary shape, increased the area of dissipation of radiator, help the heat radiation of product, and after adopting the die casting emission technology, can be arbitrary shape increase heat-conducting area at copper alloy base material and magnesium alloy combination interface, and have high heat conduction, fast heat radiation, in light weight, low cost and other advantages, so producing radiator, the present invention has good development prospect.
