Irwin-Industrial is a wholesale aluminium heatsink manufacturer offering heatsink design, aluminum heatsinks, custom heatsinks, clip heat sinks, aluminium extrusion profiles,heatsink fans, thermal management, electronic cooling, thermal interface and phase change materials. Aluminum heat sinks can be used for both passive or active thermal management at the component, board or system level. Irwin-Industrial can design, develop and manufacture plate and pin fin aluminum heat sinks to fit your financial or thermal budget. Forged pin fin aluminum heat sinks are considered to be very thermally efficient due to the low thermal resistances they provide per unit volume. The powerful thermal performances generated by pin fin aluminum heat sinks are a product of an efficient physical structure and the use of highly conductive materials. In a fashion similar to other technically advanced applications, embedded applications typically require highly efficient aluminium heat sinks that provide low thermal resistances per given volume.
