- noun a metal device used to conduct heat away from an electronic component to prevent damage
- noun a place that can absorb extra heat
- A material or object which helps dissipate unwanted heat from components, circuits, devices, equipment, enclosures, or systems, enabling them to continue working within a safe temperature range. It does so by absorbing heat and conducting it away to a surface from which it is dissipated into its surroundings. Heat sinks are used, for instance, to protect power transistors. Also called sink (3).
