An extruded aluminium heat sink is a component used to dissipate heat from electronic devices. It is made from aluminium extrusion, which is a process where aluminium is pushed through a die to create a specific shape. The heat sink's design allows for maximum surface area to be exposed to the surrounding air, which facilitates heat transfer.

The heat sink is typically attached to the device using thermal interface materials such as thermal paste or thermal pads. As the electronic device generates heat, the heat is transferred to the heat sink, which then dissipates the heat to the surrounding environment.

Extruded aluminium heat sinks are commonly used in electronic devices such as computers, LED lights, and power supplies. They are preferred over other materials due to their high thermal conductivity, lightweight, and cost-effectiveness. Additionally, the extrusion process allows for a wide range of shapes and sizes to be produced, making them highly customizable for specific applications.
