Active Liquid Heat Sink Definition

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.

Active liquid heat sink definition.

The mentioned heat sink is part of an experimental setup presented in fig. 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. A heatsink is a passive heat exchanger that transfers heat. In addition to the hsf a heat sink compound is sometimes used.

The vapor then travels along the heat pipe to the cold interface. Active heat sinks vs. The picture is an example of a heat sink that has both active and passive cooling mechanisms. Cooling fluid from the reservoir was pumped 1 through the flow meter 2 to the heat sink 3.

Heat sinks are most commonly utilized in active passive or hybrid configurations. 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. Passive heat sinks rely on natural convection meaning the buoyancy of hot air alone causes the airflow generated across the heat sink system. Heat sink definition is a substance or device that absorbs or dissipates especially unwanted heat as from a process or an electronic device.

Another type of active heat management is pumped liquid cooling. 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. 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. Passive heat sinks have no.

Heat sinks are commonly used in all cpus and are also. These systems are advantageous as they do not require secondary power or. 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.

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 are often used in conjunction with passive heat sinks. A fan heat sink assembly from amd provides forced air convection to cool a cpu.
