The heat sink (or heatsink) is an essential component in the manufacture of electronic devices. Devices such as computers, cell phones, and most other electronic devices, generate heat–and a lot of it–and if that heat is not dissipated somehow, it will reduce the efficiency of, or even destroy the essential components of the device such as a processor.
There are two major types of heat sinks:
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 are often used in conjunction with passive heat sinks.
Passive heat sinks have no mechanical parts, making them dependable and easy to install within electronics. Typically, these are constructed of aluminum and designed to spread heat over a large area and then radiating it away from the delicate components. shaped into thin strands known as fins. Fins allow air to slip in between them and help carry away heat for more efficiently than could be done by a solid block of aluminum of the same size.
