The high-efficiency thermal conductivity of CNC machined aluminum heat sink is the decisive factor for maintaining good heat dissipation and the most ideal medium for heat energy conversion. The characteristics are: less time, fast heating, high efficiency, light and smart, and easy to process. For radiators of the same specifications, the weight of aluminum profiles is 1/3 of that of steel radiators.
CNC machining of aluminum heat sinks, and other materials which have more advantages: small number of rapid prototyping, such as energy saving, decorative, price, weight, etc., other.
The CNC machined aluminum heat sink is the lightest among a variety of radiators, and it is easy to transport and install. At the same time, it has good thermal conductivity, large heat dissipation, fast heat dissipation, and high metal thermal strength. Because it is machined and formed, it can be machined into various shapes of radiators, so the appearance is novel and beautiful, and the decoration is strong. Since aluminum oxide is the best protective film to produce after aluminum oxidation, it can prevent it from further oxidation, so it is not afraid of oxidation and corrosion, and its moderate price is very popular among working class.
With the rapid development of electronic technology and the increasingly widespread application of electronic products, aluminum alloy electronic radiators have become indispensable parts of electronic components. Aluminum alloy uses pure aluminum or aluminum alloy as raw materials. Heat sinks with different cross-sectional shapes can be formed through processes such as smelting, CNC processing, and extrusion. Then, it can be processed into an electronic radiator with fine surface, stable performance and superior quality under surface treatment processes such as wire drawing, sandblasting, electroplating, laser screen printing, and anodizing.
The density of aluminum alloy is about one-third that of steel and copper. The radiator is made of aluminum alloy, which is lighter. The electronic radiator made of lightweight aluminum alloy is relatively light and thin, which is in line with the development trend of light and thin electronic products.
The working environment of electronic radiator is complicated, and its anti-corrosion performance must be considered when selecting raw materials. A dense oxide film is formed on the surface of aluminum alloy, which can play a role in preventing corrosion. After further surface treatment process, the corrosion resistance of aluminum alloy heat sink is greatly improved.
Heat conduction and heat dissipation performance is one of the main indicators to measure the raw materials of the radiator. Aluminum alloy has good thermal conductivity.
Compared with aluminum alloy, copper is superior in thermal conductivity, but it cannot achieve light weight and thinness, and the production cost is higher than aluminum alloy. Therefore, aluminum alloy radiators are more likely to be welcomed by manufacturers on the market.
Non-magnetic is actually an important performance of electronic radiators. Aluminum alloy is not magnetic. In order to avoid signal interference, aluminum alloy radiators are used in electronic products to avoid signal interference with the normal operation of electronic products.
Aluminum alloy has high plasticity, and most of the radiator materials are made of aluminum alloy. Because the aluminum alloy with excellent plasticity can be processed into radiators of different shapes. The surface of the radiator is processed with wire drawing, sandblasting, laser engraving and silk screen printing, which can make the radiator have a more diverse appearance.
The reason why machined aluminum alloy is so popular in the radiator industry is that its application range is further expanding. The main reason is that aluminum alloy has good corrosion resistance, good thermal conductivity, and light weight, which is very suitable as an ideal material for electronic radiators.
