Aluminum Square Radiator Extrusion

Aluminium square heat sink is a device used to dissipate heat from electronic components such as CPUs, GPUs, and power transistors. It is made of aluminium, a material with good thermal conductivity, and is designed in a square shape to maximize the surface area for heat dissipation. 

Aluminum heat sink, which has a smooth, shiny surface but is not polished or coated. This finish is suitable for most applications where appearance is not critical, as it provides good heat dissipation and is cost-effective. However, some heat sinks may be anodized or coated with a protective layer to improve their durability and corrosion resistance. Polished or coated finishes may also be used for aesthetic purposes or to match the appearance of other components in a system.

The heat sink is attached to the electronic component using thermal paste or a thermal pad, which ensures good thermal contact between the two surfaces. As the electronic component generates heat, the heat sink absorbs the heat and transfers it to the surrounding air, which is then dissipated through natural convection or forced air cooling. 

The square shape of the heat sink allows for efficient heat dissipation in a compact form factor, making it a popular choice for many electronic devices.Aluminium square heat sinks are commonly used in desktop computers, laptops, and other electronic devices to prevent overheating and improve performance and reliability.
