Abstract
A Mg-alloy radiator contains Mg (more than 85.6%), Al (2.5-9.7 %), Zn (0.2-1.0%), Mn (0.1-0.3%), Si (0-0.1%), Fe (0-0.005%), Cu (0-0.3%), Ni (0-0.002%), RE (1.5-3.0%) and impurities (0-0.002%). It is made up of Mg-alloy ingot through heating it to 250-400 deg.C and extruding out at 200-250 deg.C, 2-8m/min and 150-210 MPa. Its advantages are light weight and high heat radiating power.
Description
Affiliated technical field
The invention belongs to a kind of radiator fin, particularly a kind of magnesium alloy radiator fin and its preparation method.
Background technology
At present, a large amount of radiator fins is made with aluminium alloy, and the proportion of aluminium alloy is bigger by 1/3rd than magnesium alloy.Be used for the occasion higher to lightweight requirements, as the CPU of computer and the wind-cooling heat dissipating sheet of video card etc., aluminum alloy heat sink is just relatively heavier, the comprehensive heat-sinking capability of aluminium alloy is also less than magnesium alloy in addition, thereby the present invention proposes to replace aluminium alloy to make radiator fin with high heat conductive magnesium alloy.
Summary of the invention
Than the lower problem of great, comprehensive heat-sinking capability, the invention provides a kind of magnesium alloy radiator fin and its preparation method at existing aluminium alloy heat radiator sheet.
Radiator fin of the present invention is identical with existing aluminium alloy heat radiator sheet on shape and structure, and crucial difference is that radiator fin of the present invention is to make production with magnesium alloy, and alloying component percentage by weight is:
| Alloying component | ??Mg | ??Al | ??Zn | ??Mn | ??Si | ??Fe | ??Cu | ????Ni | ????RE | Other impurity |
| Content (%) | ＞85.6 | ?2.5-9.7 | ?0.2-1.0 | ?0.1-0.3 | ＜0.1 | ＜0.005 | ＜0.3 | ＜0.002 | ?1.5-3.0 | ＜0.002 |
The manufacture method of radiator fin of the present invention comprises: produce the semi-continuous casting ingot that meets specification requirement with the semi-continuous casting method, and the processing steps such as extrusion modling of radiator fin.The technological parameter of semi-continuous casting is identical with the semicontinuous casting technique parameter of other magnesium alloy; The extrusion forming process parameter is: extrusion ingot temperature 250-400 degree, and recipient temperature 200-250 degree, muzzle velocity 2-8 rice/minute, extruding force is in the 150-210 MPa.The section bar semi-finished product that extruding is good can be finished the production of magnesium alloy radiator sheet again through cutting action.
Use the radiator fin of the inventive method manufacturing to have advantages such as in light weight, that heat-sinking capability is good.
The specific embodiment
Processing step is as previously described at first prepared a kind of semicontinuous ingot casting of magnesium alloy, and its composition is: Mg88%, and Al9%, Zn0.5%, Mn0.2%, RE2%, other composition requires to meet the composition range described in the summary of the invention.The diameter of semicontinuous ingot casting is 100 millimeters, cuts into 400 millimeters long, as the extrusion ingot of next step production.For the alloy of this composition, squeezing parameter is: extrusion temperature 300 degree, recipient temperature 220 degree, 5 meters/minute of muzzle velocities, extrusion ratio 80: 1.The section bar semi-finished product that extruding is good can be finished the production of magnesium alloy radiator sheet again through machining.
