Abstract
The invention relates to a superconductive aluminum-based alloy for an LED heat dissipation device, and belongs to the technical field of heat dissipation, which is used for improving the heat dissipation speed of an LED heat dissipation plate and particularly suitable for heat dissipation devices of an LED solid light source. The conventional LED heat dissipation device dissipates heat through an aluminum alloy radiator; and more aluminum alloy is required when the heat value is higher, so that the weight and volume of the radiator are enlarged. Various elements are added into smelted molten aluminum liquid according to the ingredients of No.6063 aluminum alloy, and the alloy comprises 9.8 to 10.8 weight parts of Gu, 0.3 to 0.4 weight part of Ni, 7.5 to 9.08 weight parts of Se and the balance of unequal elements, so that the heat dissipation effect is greatly enhanced, the defects are overcome and the problem of heat dissipation of a power LED is solved. The superconductive aluminum-based alloy has the advantages of advanced process, convenient operation, stable performance, difficult drying, safety, energy conservation and the like.
Description
Technical field
The present invention relates to a kind of superconductive aluminum-based alloy of the LED of being used for heat abstractor, be used to promote the radiating rate of LED heating panel, be specially adapted to the radiating element of LED solid light source.Belong to the heat dissipation technology field.
Background technology
LED (Light Emitting Diode, light-emitting diode) is a kind of solid-state semiconductor device that can convert electrical energy into visible light, and it can directly be converted into light to electricity.LED has that volume is little, power consumption is low, long service life, high brightness, low in calories, environmental protection, and the sturdy and durable good characteristic that waits is acknowledged as optimal light source.Conventional LED heat abstractor is to dispel the heat by aluminium alloy heat radiator, realize the purpose of collecting and distributing heat by aluminum alloy materials, thereby the caloric value height of healing needs aluminium alloy the more, make heatsink weight and volume increase thereupon, strengthen cost, the waste resource, and radiating effect is poor, reduce the useful life of LED, overcome the above problems, do not increased the weight and volume of radiating equipment, by changing the composition of radiating equipment, so that heat transferred LED is to the requirement of ambient temperature, thereby people wish to have a kind of novel alloy material that can overcome above-mentioned defective to satisfy the requirement of LED to heat radiation.
Summary of the invention
The object of the present invention is to provide a kind of superconductive aluminum-based alloy of the LED of being used for heat abstractor, increased the radiating rate of radiator, realize cold operation, prolong the useful life of LED.
The present invention is achieved by the following technical solutions
(1) the fine aluminium pyrolytic semlting is melted;
(2) composition by aluminium alloy 6063 trades mark adds various elements in smelting the aluminium liquid that melts, and wherein the composition by weight of each element is respectively: cobalt Co:9.8-10.8, silicon Si; 0.808-0.62, copper Gu:8.08-10.35, magnesium Mg:0.45-0.9, zinc Zn; ≤ 0.13, manganese Mn :≤0.15, titanium Ti :≤0.15, chromium Cr :≤0.15, iron Fe:0.01-0.35, nickel: 0.28-0.36;
(3) above-mentioned aluminium alloy mixing material is carried out cold treatment and make aluminium ingot;
(4) with aluminium ingot by the pressurization of heating, make the semi-finished product of suitable shape as required of the section bar extruder;
(5) semi-finished product are made into the radiator blank of different shape through machining, form the superconduction aluminium alloy heat radiator after the oxidation.
The present invention has and reduces cost, and technology is simple, and is easy to use, processability good, advantages such as energy-conserving and environment-protective.
Embodiment
At first make aluminium alloy superconduction hot material, its concrete rules are as follows:
Prepare furnace charge (fine aluminium) → shove charge → melt → the add silicon → magnesium → stirrings → sample analysis of skimming → add → adjustment composition (by the interpolation of alloy requirement composition) → stir → skim → fall stove → refining → skim and cover → leave standstill temperature control cooling → oxygen determination → come out of the stove → prepurging.Temperature is controlled between 750 ℃-760 ℃ in the said process, and the material that guarantees to come out of the stove reaches technological requirement, and prevents that oxygen uptake from causing oxidation to reduce material property.The alloy blank of producing is carried out the section bar extrusion process becomes mould process section bar and cutting, through mill, technology such as brill produces the radiator base material.Clean again at last, oxidation.Get effective area and all be each one of 160 square centimeters of above-mentioned alloy sheets and common aluminum alloy plate, be respectively applied for the radiator of the led light source of 5w12v410mA, radiator and led light source contact area are 5cm * 3cm, and add heat-conducting silicone grease.40 ℃ of 10 minutes, ambient temperature switch on.Make radiator and compare with the radiator made from conventional aluminium alloy with the present invention, the use amount of aluminium has reduced 30%, and heat conductivility has improved 30% (seeing the following form).By the about 6750-7500 kilogram of CO2 emissions of aluminium production power consumption per ton, to calculate according to the about 50g aluminium of Lantern Festival, annual demand needs 1.5 hundred million aluminium that will save 7500 tons of LED bulb of aluminium radiator, reduces CO2 emission
Ton.
