A heat pipe includes a metal tube and an amount of fluid sealed in the copper tube. The metal tube may include an inner surface. The inner surface is patterned to define at least one pitch and at least two grooves. A given pitch separates adjacent grooves. The amount of fluid may include a liquid and carbon nanotubes, carbon nanocapsules and/or metal nanoparticles suspended therein.
