Product Name
Alpha Nain Aluminum Heatsink

Heat sinks or radiators are used to dissipate heat from electronic components and chips such as processors, switching components, regulators, ICs, state-of-the-art relays, and a variety of semiconductors. As the name implies, one of the main methods of heat dissipation is radiation. Depending on the Stephan-Boltzmann relationship, the amount of radiation depends on the temperature difference between the emitter and the receiving object (usually the environment), the surface area, and the surface radiation coefficient. The ambient temperature or the amount of heat produced by the chip or processor is usually not controlled, so it is attempted to increase the rate of heat dissipation through radiation by increasing the surface area and increasing the surface radiation coefficient. Increasing the level is done through geometric design, but increasing the radiation coefficient is usually not easily possible.
Heat sinks in the industry are usually made of aluminum and extruded. Aluminum (α) has a low coefficient of radiation and is about 0.04 to 0.66, while nanosilver aluminum oxide coatings have a radius of about 0.9. Therefore, modification of the surface of aluminum radiators with oxide nanostructured coatings can significantly improve their heat transfer coefficient through radiation, but this is not the most important advantage of these coatings. Oxide nanostructured coatings, while heat conductors, are considered electrical insulators, so electronic components can be dissipated without worrying about connection to the field. Oxide nanostructured coatings have other advantages as well.

Aluminum-covered heatsink compared to uncoated

1- Heat sink is electric insulation and thermal conductor. Therefore, it can be used jointly for chips that have a base attached to the heat dissipation section.
2- The probability of electric shock, connection to other parts, connection to the board, spark and fire, etc. will be greatly reduced.
3- The radiation coefficient increases significantly and the heat transfer increases in this way.
4- The surface of the heatsink is hard and very resistant to corrosion, which is not an important advantage for cold air radiators, but it is a key preference for water radiators (or any other fluid).
