Abstract
The invention relates to a novel light emitting diode (LED) radiator base material used for promoting the radiating velocity of an LED radiating plate and particularly suitable for a radiator of an LED solid light source, and belongs to the technical field of radiation. The conventional LED radiating device dissipates heat through an aluminum alloy radiator, and the higher the calorific power is, the more the aluminum alloy is required, so that the weight and the volume of the radiator are increased. Various elements are added into molten aluminum according to the components of aluminum alloy brand 6063, the Gu is regulated to be between 9.8 and 10.8, and meanwhile, 0.3 to 0.4 percent of Ni, 7.5 to 9.08 percent of Se and other unequal amount of elements are added, so that the radiating effect is greatly enhanced, the defects are overcome, and the problems of a power type LED radiator are solved. The base material has the advantages of advanced process, convenience in operation, stable performance, drying resistance, safety, energy conservation and the like.
Description
Technical field
The present invention relates to a kind of New LED scatterer base material, be used for the superconductive aluminum-based alloy of LED heat abstractor, 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, photodiode) is a kind of solid-state semiconducter device that electric energy can be converted into visible light, and it can directly be converted into light to electricity.LED has that volume is little, and current consumption is low, long service life, and high brightness, low in calories, environmental protection, 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 thermal 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, has reduced the work-ing life of LED.Overcome the above problems, do not increase the weight and volume of radiating equipment, by changing the composition of heat sink material.So that the requirement of LED to envrionment temperature satisfied in the heat transmission.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 New LED scatterer base material, be used for the superconductive aluminum-based alloy of LED heat abstractor, increased radiator heat-dissipation speed, realize cold operation, prolong the work-ing life of LED.
The present invention is achieved by the following technical solutions (1) melts the fine aluminium pyrotic smelting; (2) composition by aluminium alloy 6063 trades mark adds various elements in smelting the aluminium liquid that melts, wherein the composition by weight of each element is respectively: cobalt Gu:9.8-10.8, silicon Si:0.808-0.62, copper Cu: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 liquid is carried out deepfreeze and make aluminium ingot; (4) with aluminium ingot by the pressurization of heating, make the work in-process of suitable shape as required of the section bar forcing machine; (5) work in-process are made into the scatterer blank of different shape through mechanical workout, 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, processibility good, advantages such as energy-conserving and environment-protective.
Embodiment
Prepare furnace charge (fine aluminium) → shove charge → melt → the add silicon → magnesium → stirrings → sampling 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 processing requirement, and prevents that oxygen uptake from causing oxidation to reduce material property.The alloy billet of producing is carried out the section bar extrusion processing becomes mould process section bar and cutting, through mill, technology such as brill produces the scatterer base material.Clean again at last, oxidation.Get useful 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 scatterer of the led light source of 5w12v410mA, scatterer and led light source contact area are 5cm * 3cm, and add heat-conducting silicone grease.40 ℃ of 10 minutes, envrionment temperature switch on.Make scatterer and compare with the scatterer made from conventional aluminium alloy with the present invention, the usage quantity of aluminium has reduced 30%, and heat conductivility has improved 30%.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 6,000 ten thousand tons of Carbon emissions.
