Skived fin heat sinks are typically made from metals with high thermal conductivity, such as copper or aluminum. Skiving is a manufacturing process in which thin fins are sliced or machined from a solid block of metal, creating a large surface area that can efficiently dissipate heat. The base plate of the heat sink may also be made from the same material as the fins or a different material with good thermal conductivity, such as copper or aluminum.
Copper is an excellent material for skived fin heat sink due to its high thermal conductivity, which is approximately 400 W/mK. This means that copper heat sinks can quickly and efficiently transfer heat away from the heat-generating component and dissipate it into the surrounding environment. Copper is also a durable and long-lasting material that is resistant to corrosion, making it a good choice for heat sinks used in harsh or demanding environments.
Aluminum is also commonly used in skived fin heat sinks due to its good thermal conductivity, which is approximately 200 W/mK. While not as high as copper, aluminum is a lightweight and cost-effective material that can be easily machined to create complex fin designs. Aluminum heat sinks are also resistant to corrosion and can be anodized or painted to improve their appearance and durability.
Lastly, in addition to copper and aluminum, other materials may also be used for skived fin heat sinks, including brass, stainless steel, and titanium. The choice of material will depend on the specific application requirements, such as thermal performance, weight, cost, and corrosion resistance.
Skived fin heat sink thermal conductivity
Skived fin heat sinks typically have high thermal conductivity due to the materials used in their construction. Skived fins are typically made from metals such as copper or aluminum, which are known for their high thermal conductivity. The base plate of the heat sink may also be made from a highly conductive material, such as copper or aluminum, to further enhance its thermal performance.
Copper has a thermal conductivity of approximately 400 W/mK, which is significantly higher than aluminum’s thermal conductivity of around 200 W/mK. This means that copper skived fin heat sinks will generally have better thermal performance than aluminum ones, all else being equal.
However, the thermal conductivity of a skived fin heat sink is also influenced by other factors, such as the size and shape of the fins, the thickness and composition of the base plate, and the overall design of the heat sink.
A well-designed skived fin heat sink can have a thermal conductivity of up to 300 W/mK, which is significantly higher than other types of heat sinks.
Overall, skived fin heat sinks are known for their high thermal conductivity, which allows them to efficiently transfer heat away from heat-generating components and dissipate it into the surrounding environment. They are commonly used in a variety of applications, including electronics, power electronics, and LED lighting, where effective thermal management is critical to maintaining device performance and reliability.
Cold rolling processes skived fin
Cold rolling is a metalworking process used to shape metal by passing it through a pair of rollers at room temperature. It is commonly used to create sheets or strips of metal with a consistent thickness and smooth surface finish. Skived fins, on the other hand, are typically created using a machining process in which thin fins are sliced or machined from a solid block of metal.
While cold rolling and skiving are both metalworking processes, they are fundamentally different in terms of the types of products they produce and the materials they work with.
In some cases, skived fins may be created using a rolling process. For example, a sheet of metal may be rolled to create a thin, flat base plate, which is then machined or sliced to create the fins. However, this process is not typically referred to as cold rolling, as the primary shaping process is the machining or slicing of the fins.
