Active Heat Sink

Cob led heat sink.

Active heat sink.

Heat sinks with these additional fans are called active heat sinks while those with the single fan are called passive heat sinks. Active heat sinks utilize forced air to increase fluid flow across the hot area. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. These generally have a fan or blower of some kind.

One example of a fan producing forced air across a. These provide excellent performance but they consist of moving parts and are on the expensive side. 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. These have no mechanical components.

The most common fan is the case fan which draws cool air from outside the computer and blows it through the computer expelling the hot air out of the rear. Active heat sinks are often used in conjunction with passive heat sinks. The fans are further classified as ball bearing type and sleeve bearing type. The ball bearing motor fans are preferred as their working span is longer and they are cheaper when it comes to a long span usage the.

The heatsink is typically a metallic part which can be attached to a device releasing energy in the form of heat with the aim of dissipating that heat to a surrounding fluid in order to prevent the device overheating. A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor there are two heat sink types. They only use the convection process to dissipate thermal energy. These are generally fan type and utilize power for cooling purpose they can also be termed as heat sink or fans.

The picture is an example of a heat sink that has both active and passive cooling mechanisms. 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.

Forced air is most commonly generated by a fan blower or even movement of the entire object such as a motorcycle s engine being cooled by the air passing along the heat sink fins designed into the engine. In solar heating an active solar heating system is a system with a fan while a passive solar heating system relies on the movement of heat without the aid of a fan.
