Abstract
A heat pipe for transferring heat from a heat source to a heat dissipater. The heat pipe includes a tube encasing a low viscosity working fluid and at least one radially segmented disk to restrict the flow of the working fluid to a single direction around the interior of closed loop of the tube. The tube additionally has a first surface adapted to contact at least a portion of a heat source, and a second surface adapted to contact at least a portion of a heat dissipater. The heat source vaporizes the working fluid, pressure forcing the fluid to circulate throughout the enclosed loop of the tube, the vapor being cooled and re-condensed while near the heat dissipater. Each radially segmented disk includes a plurality of segments designed to introduce turbulence into the fluid flow to increase heat transfer rates.
