Extrusion Heat Sink :Extrusion Heat Sink is a commonly used type of heat sink, typically made of aluminum. They are created by extruding aluminum billets into a specific shape to create the heat sink’s exterior, which is then machined and surface-treated to enhance its heat dissipation efficiency.Extrusion Heat Sinks are typically designed with fin structures to increase surface area and improve heat dissipation capabilities. They can also be designed for specific applications, such as compact heat sinks used in electronic devices that need to be installed in narrow spaces.Extrusion Heat Sinks are typically used in conjunction with other cooling devices such as fans to enhance heat dissipation efficiency. They can be used in a variety of applications such as computers, LED lights, and electronic devices. Due to their relatively low manufacturing cost, they are an economical and practical choice for heat sinks.
