Pressfin Heat Sinks
- 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 & the device. - Round pins offer a greater surface area when compared to square pins. - Pressfin heat sinks react much faster 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 & weight are at a premium. - Manufactured from AI99,0-99 pure aluminium with a thermal conductivity of 210~236 W/mk. - 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. - Sizes from 10 x 10mm up to 100 x 100mm with a wide variety of pin forms.
