Aluminium Foil Roll 8011 For Heat Dissipation
Different heat dissipation materials have different thermal conductivity. They are silver, copper, aluminum and steel. Silver radiators are too expensive, the best way is to use copper. Although aluminum is cheap, its thermal conductivity is not as good as copper. Commonly used heat sink materials are copper and aluminum alloys, which make up for the advantages and disadvantages of copper and aluminum. Copper has good thermal conductivity, but high processing cost, expensive raw materials, small heat capacity, and easy oxidation. However, pure aluminum is too soft to be used directly, and only the aluminum alloy used can provide sufficient hardness.
Aluminum foil has good thermal conductivity, low density, and is not easy to oxidize (after oxidation, dense aluminum oxide can be formed on the surface to prevent further oxidation). The price of aluminum is relatively lower than that of copper. Therefore, most radiators now use aluminum or aluminum alloys. Kind of factors.
Choose the material of the radiator, aluminum has better heat dissipation than steel, so most of the radiator uses aluminum. The same amount of heat can increase the temperature of a heat sink made of two metals of the same size. Among them, aluminum will rise to a higher temperature, which means that the temperature difference with the environment is greater, and this is greater. Some temperature differences will accelerate heat dissipation. The biggest difference between aluminum radiators is that they have good corrosion resistance. Because aluminum profiles have corrosion resistance characteristics, because aluminum and oxygen will form an oxide film on the surface of aluminum profiles, it has great corrosion resistance to corrosive objects. The role of. Therefore, its corrosion resistance is quite good.
