What Is Extruded Heat Sink?
The most commonly used material for heat sink extrusion is aluminum due to its excellent thermal conduc— tivity, lightweight nature, and ease of extrusion. Aluminum alloys such as 6061 and 6063 are frequently chosen for their balance of thermal performance, cost—effectiveness, and mechanical properties.
Copper is another material with superior thermal conductivity that can be used for heat sink extrusion, es— pecially in applications where maximum heat dissipation is required. However, copper is heavier and gener— ally more expensive than aluminum.
In some specialized cases, materials like stainless steel or even certain plastics might be used for heat sink extrusion, depending on specific thermal and mechanical requirements.
Ultimately, the choice of material depends on factors such as the heat load, thermal conductivity needs, weight constraints, and budget considerations for a given application.

Surface Coating Options For Heat Sink Extrusion
An extruded heat sink functions as a crucial thermal management component in electronic devices and sys— tems. Its primary purpose is to efficiently dissipate heat generated by high—power electronic components, preventing overheating and ensuring optimal performance and longevity.
Heat Absorption: The heat sink is typically attached to the electronic component, such as a CPU or GPU, through a thermal interface material. This allows for efficient transfer of heat from the component to the heat sink.
Enhanced Surface Area: Extruded heat sinks are designed with numerous fins or ridges that significantly in— crease the surface area available for heat dissipation. The fins create pathways for air to flow through, im— proving convective cooling.
Heat Spreading: Once the heat reaches the heat sink, its high thermal conductivity material, often alumi- num, rapidly spreads the heat across its surface. This spreading helps distribute the heat evenly and pre— vents localized hotspots.
Airflow: As air moves across the heat sink's finned structure, it absorbs the heat, cooling the heat sink. This process is known as convective heat transfer.
Heat Dissipation: The heat absorbed by the air is then carried away, reducing the temperature of the heat sink and the attached electronic component. This cooling effect prevents the component from reaching critical temperatures.
Temperature Reduction: Through the heat sink's efficient heat dissipation, the temperature of the electronic component is lowered, maintaining its optimal operating conditions and preventing potential performance degradation.
Continuous Cycle: The process of heat absorption, spreading, and dissipation continues as long as the electronic component generates heat. This cycle ensures that the component remains within safe tempera— ture limits, contributing to its reliability and longevity.
