Why Aluminum Heat Sinks Are Necessary？
What are heat sinks used for?
A heat sink is a widely used method of cooling parts or components that become hot when in use. Many types of electronic and mechanical devices or machinery use heat sinks to help them dissipate the heat they generate.
How a heat sink works:
It will divert the heat flow away from the hot device. They do this by increasing the surface area of the device. In order for radiators to work properly, they must have a higher temperature than their surroundings to transfer heat.
Why Aluminum Heat Sinks are Important?
Heat sinks are almost always made of metal, most commonly copper heat sinks or aluminum heat sinks. Both types of heatsinks provide electronic devices with higher operating temperatures and increased longevity. But why are aluminum heatsinks irreplaceable? This is because it offers these advantages:
1. Light weight
Aluminum is less dense, so it will be lighter than any other as a heat sink. It is easy to process. When making large heat sink, the use of aluminum can greatly reduce the overall weight of the radiator, reduce the cost of production and easy to transport and install.
2. Good thermal conductivity
Aluminum has a high thermal conductivity. So when the radiator is made of aluminum, it can effectively transfer the heat to the cooling fins and quickly dissipate the heat. The effect of heat dissipation is improved. Compared with other materials, the heat dissipation performance and heat conduction ability of aluminum is very excellent.
3. Easy to processing
Aluminum heat sinks are easy to process and shape. Aluminum profiles are extruded into molds to become various types of heatsinks. Shapes of aluminum heatsinks such as round, hollow, fluted and hollow circle can be obtained by making various types of molds. Subsequently, heat sinks can be processed by stamping and CNC machining or more complex heat sinks.
4. Low Cost of aluminums
The manufacturing cost of aluminum heat sinks is much lower than other heat sink materials. For example, copper, zinc, ceramic and other heatsink materials. It is simple to process and less expensive to mine than other metals. Because aluminum is the most common metal on earth, and processed aluminum heatsinks are low maintenance. Making it the material for almost all heatsinks.
5. Aluminum heat sinks come in more diverse shapes
Aluminum heat sinks are obtained through the process of aluminum extrusion, which allows extruded aluminum to be designed in different shapes. This means that design requirements that cannot be met by other metal heatsinks can be achieved with aluminum. For example, complex server heatsinks or AI computer heatsinks require extruded aluminum heat sinks to help reduce operating temperatures.
6. Aluminum heatsinks are fully recyclable
As time grows, the heat sink will become useless in the future. It may be damaged or corroded, and it can be annoying to have to deal with these large numbers of heatsinks. The recycling of zinc and copper metals produces toxic gases or pollutants, so we can’t landfill it or burn it. However, aluminum heatsinks are fully recyclable, even aluminum alloys can be fully recycled and converted into new aluminum.
In summary, the reasons why aluminum heat sinks must be chosen contain: low cost, light weight, high thermal conductivity, easy to process, and more. In the future with the growing demand for electronic components, the market for aluminum heatsinks will attract more consumers.
