heat sink

A reservoir for excess heat, especially in a mechanical or electrical device.

Note: One obstacle to the loading of circuits onto microprocessors is the heat generated by electrical circuits. Effective heat sinks, such as metal fins on top of a microprocessor, can provide part of the solution to this problem.

heat sink hardware
/heet sink/ (from "sink", electronics jargon for something which takes in current) A piece of thermally conductive metal attached to a semiconductor or other electronic device and designed to prevent it from overheating by conducting heat away from it and radiating it to the environment. Heat sinks often have fins to increase their surface area. They occasionally have fans attached. Heat sink compound can be smeared between the device and the heat sink to improve thermal conduction.
