What is the function of a heatsink in electronic equipment?

Explanation:
Heat removal from electronic components is what a heatsink does. It uses a material with high thermal conductivity and a large surface area (often with fins) to spread heat away from hot parts and transfer it to the surrounding air, aided by natural or forced convection. This keeps temperatures within safe limits so performance remains stable and reliability is maintained. Heatsinks are passive devices and do not store electrical charge, regulate voltage, or amplify signals, which are roles of other components.
