Problems solved by technology

Therefore, the higher the calorific value, the more aluminum alloy is required, which increases the weight and volume of the radiator, increases the cost, wastes resources, and the heat dissipation effect is poor, which reduces the service life of the LED.

Embodiment Construction

[0011] The operation steps are as follows:

[0012] 1. Prepare furnace material (pure aluminum)→load furnace→melt→add silicon→slagging off→add magnesium→stirring→sampling analysis→adjust composition (add according to alloy requirements)→stirring→slagging off→smelting furnace→refining→slagging off Covering → cooling under temperature control → measuring oxygen → taking out the furnace → cleaning the furnace.

[0013] During the above process, the temperature is controlled between 750°C and 760°C to ensure that the materials out of the furnace meet the process requirements, and to prevent oxidation caused by oxygen absorption to reduce material performance.

[0014] 2. Extrude the produced alloy billet into a mold process profile and cut it, and make the radiator base material by milling, drilling and other processes. Finally, it is cleaned and oxidized.

[0015] 3. Take the above-mentioned alloy plate and ordinary aluminum alloy plate with an effective area of ​​160 square ce...

Abstract

The invention relates to a preparation method and modified components of a novel high-efficiency superconducting aluminum-alloy heat-dissipating material, particularly suitable to serve as the material of LED (light-emitting diode) solid-light-source heat-dissipating devices, belonging to the technical field of metallurgy. The modified components comprise smelted and molten aluminium, various elements, Gu, Ni and Se. All the elements are added into the smelted and molten aluminium according to the components of aluminum alloy 6063, the weight part of the Gu is adjusted to be 9.8-10.8, and 0.3-0.4 part of the Ni and 7.5-9.08 parts of Se are added. The preparation method has the advantages of cost reduction, simpleness process, convenience in use, good processability, energy saving and environment friendliness.

Description

technical field [0001] The invention relates to a modified component and a production method of a novel high-efficiency aluminum alloy heat dissipation material, which is particularly suitable as a material for matching LED solid light source heat dissipation devices, and belongs to the field of metallurgy technology. Background technique [0002] In recent years, LED (Light Emitting Diode, Light Emitting Diode) has been recognized as the most ideal light source, and thus has been widely used. As a result, the heat dissipation effect of the matching LED cooling device and the cooling device has also been brought up on the agenda. The traditional LED cooling device dissipates heat through an aluminum alloy radiator, which is made of aluminum alloy material to achieve the purpose of collecting and dissipating heat. Therefore, the higher the calorific value, the more aluminum alloy is required, which increases the weight and volume of the radiator, increases the cost, wastes r...
