Thermodynamics. any environment or medium that absorbs heat.
Also, heatsink. Electronics. a metallic heat exchanger designed to absorb and dissipate excess heat from one of the devices, as a transistor or resistor, in a circuit.
a metal plate specially designed to conduct and radiate heat from an electrical component
a layer of material placed within the outer skin of high-speed aircraft to absorb heat
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.
