Cold Forged Heat Sinks, Cold Forged Pin Fin Heat Sinks ...

Cold forging is a manufacturing process in which the aluminum or copper heat sink is formed by using localized compressed forces. Fin arrays are formed by forcing material into a molding die by a punch. The process ensures that no air bubbles, porosity or any other impurities are trapped within the material and thus produces exceptionally high quality products

What is a Heat Sink Types and their Inportance

Heat sink. Heat sink is an electronic component or a device of an electronic circuit which disperses heat from other components mainly from the power transistors of a circuit into the surrounding medium and cools them for improving their performance, reliability and also avoids the premature failure of the components. For the cooling purpose,it incorporates a fan or cooling device.

Heat Sinks Columbia Staver

Cold Forging. Cold forging is a cold working process. Aluminium is squeezed by a press into the closed die, the resultant heat sink taking on the shape of the void in the die. This process is also known as cold heading. Cold forged heat sinks often have high performance compared with other technologies, mainly because any increase to the surface area of a heat sink will almost always result in ...

What is a Heat Sink Types and their Inportance

Aluminum heat sinks are also called as extruded heat sinks as they can be made using extrusion. Stamped Heat Sinks . These are made of metals that are stamped to form a particular shape. This stamp creates the heat sinks whenever metal is moved through the stamping machine. These are cheaper compared to extruded heat sinks. These are used for lowpower applications and hence these are low
