Abstract
A re-entrant groove heat pipe provides capillary channel fin surfaces which are smooth, continuous, and offer a large radius of curvature upon which an extended thin film of working liquid may develop. Superior formation of thin films of the working fluid allows heat to be conducted more readily between the surface of the heat pipe and the surface of the fluid where evaporation and condensation takes place.
