Construction

  • The substance or environment into which heat is discharged after its removal from a heat source, as by a heat pump.
  • Any medium capable of accepting discharged heat.

Electronics

  • 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).
  • Any material, such as a solid or a fluid, which serves to protect components, circuits, devices, equipment, enclosures, or systems, by removing heat. Also called sink (4).
