Cultural definitions for heat sink

heat sink

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

notes for heat sink

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.

Scientific definitions for heat sink

heat sink

A protective device that absorbs and dissipates the excess heat generated by a system.

An environment capable of absorbing heat from substances within it (and with which it is in thermal contact) without an appreciable change in its own temperature and without a change in its own phase.
