1. A method of forming an annular wick for a heat pipe, the method comprising:
forming a plurality of layers of wick material around an elongate rod;
placing the elongate rod and the plurality of layers of wick material into a central die opening of an annular die assembly;
placing the elongate rod, the plurality of layers of wick material, and the annular die assembly into a central clamp opening of a clamp, wherein the clamp is configured to hold the elongate rod, the plurality of layers of wick material, and the annular die assembly together; and
heating the elongate rod, the plurality of layers of wick material, the annular die assembly, and the clamp to a temperature sufficient to thermally expand the elongate rod toward the central die opening of the annular die assembly to compress the plurality of layers of wick material between the elongate rod and the central die opening of the annular die assembly.
