Active Liquid Heat Sink Definition

Passive heat sinks have no.

Active liquid heat sink definition.

Cooling fluid from the reservoir was pumped 1 through the flow meter 2 to the heat sink 3. 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. 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. The picture is an example of a heat sink that has both active and passive cooling mechanisms. Another type of active heat management is pumped liquid cooling. 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. These systems are advantageous as they do not require secondary power or. 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 sinks are most commonly utilized in active passive or hybrid configurations.

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 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. The mentioned heat sink is part of an experimental setup presented in fig. The vapor then travels along the heat pipe to the cold interface.

After passing the heat sink the liquid was cooled down in the external heat exchanger 4 and collected in the reservoir 5. 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. Heat sinks are commonly used in all cpus and are also. A heatsink is a passive heat exchanger that transfers heat.

Heat sink definition is a substance or device that absorbs or dissipates especially unwanted heat as from a process or an electronic device. In addition to the hsf a heat sink compound is sometimes used. A fan heat sink assembly from amd provides forced air convection to cool a cpu.
