Pressfin Heat Sinks - Round Profile / TPFR Series

Aluminium round pressfin heat sinks are 30-40% more efficient when compared to extruded or die cast heat sinks, thus ensuring a low thermal difference between the heat sink and the device. They react much faster in applications as the manufacturing process ensures the atomic structure of the aluminium is in the direction of the heat flow.

They are particularly suitable for applications generating high levels of heat and where space and weight are at a premium. Manufactured from AI99,0-99 pure aluminium with a thermal conductivity of 210 ~ 236 W/mk. The round pins offer a greater surface area compared to square pins.

Very smooth mounting surface <8Rz, ensuring low thermal impedance from the contact area. Fully automated "one movement" manufacturing process produces a 20% cost saving when compared to extruded or die cast heat sinks.
