Abstract
A heat pipe is provided, which includes at least one outer structural wall, a wicking structure, and an inner retaining wall for the wicking structure. The outer structural wall has condenser, intermediate, and evaporator sections sequentially after one another. The wicking structure includes a plurality of wicking components onto which a fluid condenses at the condenser section when heat transfers therefrom out through the condenser section, flows thereon through the intermediate section, and evaporates therefrom when heat transfers thereto through the evaporator section. The wicking components are held in place between the intermediate section and an outer surface of the inner retaining wall. The fluid evaporating from the evaporator section recirculates past an inner surface of the inner retaining wall to the condenser section.
