Heatsinks are high-surface-area passive cooling devices used to remove heat from electronic and mechanical devices. They function by dissipating heat into the surrounding air or fluid via pins or fins. Aluminum and copper are commonly used due to their high thermal conductivity, with copper being a better conductor of heat than aluminum. Factors, such as protrusion design, attachment method, and coolant circulation systems, can significantly impact cooling efficiency.
