A heat sink is an electronic device made from materials with good thermal conductivity. It is attached to electronic components to remove excess heat, prevent overheating and improve reliability and performance.

Heat sinks work based on the principle that heat flows from higher temperature areas to lower temperature areas when a temperature difference exists. This heat transfer follows Fourier’s law of heat.

Heat can be transferred in three main ways. Through conduction, through convection and through radiation. Heat sinks use these methods to safely move heat away from electronic components.

This video explains the idea in a clear and visual way.
