Improved double-wall artery high capacity heat pipe
Abstract
The double-wall artery heat pipe is a novel commposite wick structure for high capacity heat pipe designs. Encouraged by the initial test results for the proof-of-concept 1.2 m long copper-water prototype, additional work has been performed to improve the transport capacity and overall performance of the double-wall heat pipe. The improved design reported in this paper incorporates segmented grooved inner tube, larger arteries, and screenless adiabatic and condenser sections to allow longer transport length. Artery priming characteristics and preliminary test results of a 2 m long 2.22 cm diameter copper-water heat pipe unit are presented.
