文摘

Porous anodic alumina nanostructures enhance radiative heat transfer of aluminum. The sealing of porous nanostructures further enhances the thermal energy transfer. Enhancement of the thermal emissivity up to 700% and the heat flux up to 300%. Demonstration of the enhancement of heat dissipation for a real heat exchange system.
