What is Skived Fin Heat Sink

 Skived is a manufacturing process in which a thermal solution is formed by scraping a solid block of copper or aluminum into a finned heat sink. This method eliminates the resistive layer that exists with the solder layer in a stacked fin heat sink because the cut fins are made from a single piece of metal.

The Skived fin heat sink is made by stripping the fins from a solid copper or aluminum strip using a sharp and precisely controlled blade tool. The turned-tooth heat sink uses SKIVING (precision cutting) technology with a thin and uniform shovel blade for consistent and better heat dissipation efficiency. The strip material is mechanically cut into thin, more straight slices at an angle. Repeated cutting forms a uniform gap structure. Used to solve the heat dissipation problem of high-power devices under air-cooled heat dissipation conditions, which can be improved compared to the inserted heat sink. 8~15% of heat dissipation efficiency.

In 2012, the high-power shovel technology independently developed by Pioneer Thermoelectric was successfully applied to SunPower 500KW centralized inverter. It has been used in large-scale applications for many years. The cumulative installed capacity of PV industry has exceeded 25GW.

With the large-scale application, Pioneer Thermal Skived fin heat sink technology has become increasingly mature, the process coverage has been expanded, the degree of automation has been gradually improved, and the cost and reliability advantages are obvious. Has been obtained communication, UPS, inverters, controllers, wind power converters and other products. ,SVG and other domestic and foreign customers.
