Active And Passive Heat Sink

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.

Active and passive heat sink.

An active heat sink has moving parts. Most heat sink applications are passive utilizing natural heat transfer fundamentals. Heat sinks are one of the most simple and common thermal management accessories. Active heat sinks vs.

Heatsinks are devices used to keep computer processing units cpus and chipsets cool. You need to be sure you choose the appropriate type based on your design needs and volume requirements. 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. Heat sinks help absorb and dissipate the heat generated by electronic devices.

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. A passive heatsink does not include a fan in the design and is typically larger than a standard model using the extra surface area of the device to improve. Active heat sinks are often used in conjunction with passive heat sinks. These systems are advantageous as they do not require secondary power or.

The terms active and passive are used frequently when referring to the storage and movement of heat. Passive heat sinks have no. It is a mass of thermally conductive metal such as aluminum or copper which is physically mounted to a heat generating component. Heat is transferred from the component to the heat sink through conduction and then dissipated through the heat sink s surface into.

Thus the second image is an active heat sink. Passive heat sinks rely on natural convection meaning the buoyancy of hot air alone causes the airflow generated across the heat sink system. Active cooling in. A passive heat sink is one with no moving parts.

Heat sinks are most commonly utilized in active passive or hybrid configurations. An example of an active solar heating system would be a set of solar panels outside the house with a fan to blow hot air. The fan is necessary because the volume of heat is to much to dissipate without forcing air through it. Most heatsinks are active meaning the design includes a small fan powered by a connector on the motherboard or a lead from the power supply unit.

The picture is an example of a heat sink that has both active and passive cooling mechanisms. Remember that sometimes active heat sinks are required for enhanced heat dissipation.
