Active Liquid Heat Sink Definition

The mentioned heat sink is part of an experimental setup presented in fig.

Active liquid heat sink definition.

After passing the heat sink the liquid was cooled down in the external heat exchanger 4 and collected in the reservoir 5. Active heat sinks are often used in conjunction with passive heat sinks. A heatsink is a passive heat exchanger that transfers heat. Cooling fluid from the reservoir was pumped 1 through the flow meter 2 to the heat sink 3.

The vapor then travels along the heat pipe to the cold interface. A heat pipe is a heat transfer device that combines the principles of both thermal conductivity and phase transition to effectively transfer heat between two solid interfaces. These systems are advantageous as they do not require secondary power or. At the hot interface of a heat pipe a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface.

Heat sinks with these additional fans are called active heat sinks while those with the single fan are called passive heat sinks. This is a coating between the device and the heat sink to improve thermal conduction. 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. This closed loop system consists of a circulating liquid coolant moved by a pump through discreet tubing to remove heat from a heat source.

In addition to the hsf a heat sink compound is sometimes used. 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 sinks vs. Passive heat sinks rely on natural convection meaning the buoyancy of hot air alone causes the airflow generated across the heat sink system.

Passive heat sinks have no. Heat sinks are commonly used in all cpus and are also. The combination of a heat sink and fan hsf is referred to as an active heat sink while a heat sink without a fan is a passive heat sink. Heat sink definition is a substance or device that absorbs or dissipates especially unwanted heat as from a process or an electronic device.

Heat sinks are most commonly utilized in active passive or hybrid configurations. The picture is an example of a heat sink that has both active and passive cooling mechanisms. 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.
