Aluminum Skiving Fin IGBT Heat Sink

     As the insulated gate bipolar transistors (IGBTs) is widely used in many industries, IGBTs are used to control electricity in various applications such as renewable energy systems, electric vehicles and industrial power supplies. Due to the operation of IGBTs generates heat, which can adversely affect their performance and reliability, the IGBT heat sink is an important part to dissipate heat and ensure the best operation of the IGBT.

   A heat sink is a passive cooling device that absorbs heat from a hot surface (such as an IGBT) and transfers it to the surrounding environment by conduction, convection or radiation, there are various types of radiators in the market such as stamped heat sinks, extruded heatsinks and skived fin heat sinks. Skiving fin heat sink is one of the most popular thermal solutions due to it has excellent thermal performance .

    The skiving process is peeling the metal sheets from the base, and interlocking the fins with designed pitch, skiving process enables high aspect ratio and fin density, the configuration ensure efficient heat dissipation by increasing the surface area in contact with the cooling medium. Compared with other types of heat sinks, aluminum skived fin heat sinks have the following advantages:

Improved thermal performance: The skiving process produces fins with thicknesses as low as 0.1 mm, resulting in a higher surface area to volume ratio, which means that aluminum skived fin heat sink can dissipate more heat per unit volume than other heat sinks. In addition, due to the high density of the fins, the heat transfer coefficient between the fins and the cooling medium is higher, which improves thermal performance.

Lightweight and compact: Aluminum skived fin heatsinks are lightweight due to their thin fins and compact size, which makes them ideal for applications where space and weight are considered, such as electric vehicles and portable electronics. Moreover their compact size allows easy integration into tight spaces and ensures efficient heat dissipation.

Cost-effective: The skiving process allows the creation of heat sinks with complex geometries without the need for expensive tooling, this makes it a cost-effective method of producing custom-designed heat sinks for specific applications. 

Improved reliability: The thermal performance of an IGBT is critical to its reliability and lifetime, IGBT overheating can lead to thermal issue and failure, Aluminum skived fin heatsinks provide improved thermal performance to keep the IGBTs cool and extending their lifetime.
