Flat and round copper heat pipes for electronics thermal management provide stand-alone cooling. The heat pumps can be combined with heat-spreading devices to deliver high levels of passive or active cooling. Each heat pipe consists of a sealed copper tube, internal copper wick structure, and distilled water as its working fluid. Liquid in the heat pipe turns to vapor by absorbing heat and removing thermal energy from hot component surfaces. The vapor travels to the cold end of the pipe, releases latent heat and condenses back to liquid. The liquid returns to the hot interface along an internal copper wick to provide continuous thermal management. The cold end of the copper heat pipe attaches easily to most heat sinks, providing effective cooling when a heat sink cannot be applied directly on a heat source.
