Is the thermal conductivity of the aluminum alloy enclosure good?

Aluminum alloy enclosures have been widely used in industry. aluminum alloy enclosures are processed on aluminum profiles obtained by aluminum stretching. It has high flexibility and can be cut at any depth. Generally, there are circuit board slots inside. As long as the circuit board is directly inserted, there is no need to fix it, and the convenience is unmatched by other types of casings.

Under satisfying the heat dissipation performance, the selection of aluminum alloy can increase the strength of the heat sink. (Pure aluminum is easy to oxidize in atmospheric environment for long-term use, and some aluminum alloys can effectively resist oxidation).

Aluminum is a good conductor of heat, and the thermal conductivity of aluminum alloy enclosures is three times larger than that of iron. Aluminum can be used to make various heat exchangers, heat dissipation materials and cooking utensils in the industry.

Other product advantages of aluminum alloy enclosure are:

1. The conductivity of aluminum is second only to silver and copper, although its conductivity is only 2/3 of copper, but its density is only 1/3 of copper, so the same amount of electricity is transported, and the quality of aluminum wire is only half that of copper wire. . The oxide film on the surface of aluminum not only has the ability to resist corrosion, but also has a certain degree of insulation. Therefore, aluminum has a wide range of uses in the electrical manufacturing industry, wire and cable industry, and radio industry.

2. Aluminum has good ductility (its ductility is second only to gold and silver), and it can be made into aluminum foil thinner than 0.01mm at 100℃～150℃. These aluminum foils are widely used for packaging cigarettes, sugar cubes, etc., and can also be made into aluminum wires, aluminum bars, and rolled various aluminum products.

3. The density of aluminum is very small, only 2.7g/cm. Although it is relatively soft, it can be made into various aluminum alloys, such as hard aluminum, super-hard aluminum, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in manufacturing industries such as airplanes, cars, trains, and ships. In addition, space rockets, space shuttles, and satellites also use a lot of aluminum and its aluminum alloys. For example, a supersonic aircraft is composed of approximately 70% aluminum and its aluminum alloys. A lot of aluminum is also used in shipbuilding, and the amount of aluminum used in a large passenger ship often reaches several thousand tons.
