Active Heat Sink Technology

An active heat sink uses an electronic device s power supply to connect to a fan or a peltier device to actively divert heat away from the components by circulating air to cool the component or conduct heat away from it.

Active heat sink technology.

The heat sink products reflect advances in the development and commercialization of active heat sink technologies achieved as part of the darpa micro technologies for air cooled exchangers mace program. Heat sinks with these additional fans are called active heat sinks while those with the single fan are called passive heat sinks. Thermacore participated in this program. Active heat sinks are often used in conjunction with passive heat sinks.

Most computers also have an additional fan installed directly above the heat sink to help properly cool the processor. Heat sinks are one of the most common forms of thermal management in technology machinery and even in natural systems. We ll address the basic working principles involved in heat sinks introduce active and passive heat sink configurations and discuss how some users. A heat sink also commonly spelled heatsink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium often air or a liquid coolant where it is dissipated away from the device thereby allowing regulation of the device s temperature.

A fan inside the computer moves air across the heat sink and out the computer. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. One ahst approach to enhancing current air cooled heat sink technology involves a blend of existing thermal heat sink solutions with targeted enhancements to improve the efficiency of air movement see fig.
