Heat sinks Thermal management (electronics)

-


heat sinks used in electronics, , have become essential modern central processing units. in common use, metal object brought contact electronic component s hot surface—though in cases, thin thermal interface material mediates between 2 surfaces. microprocessors , power handling semiconductors examples of electronics need heat sink reduce temperature through increased thermal mass , heat dissipation (primarily conduction , convection , lesser extent radiation). heat sinks have become essential modern integrated circuits microprocessors, dsps, gpus, , more.


a heat sink consists of metal structure 1 or more flat surfaces ensure thermal contact components cooled, , array of comb or fin protrusions increase surface contact air, , rate of heat dissipation.


a heat sink used in conjunction fan increase rate of airflow on heat sink. maintains larger temperature gradient replacing warmed air faster convection would. known forced air system.
