Claims
- 1. A method of manufacturing a field-serviceable, spirally-finned, cylindrical heat pipe apparatus having a longitudinal axis of symmetry, comprising the steps of:
- welding end caps to each end of a cylindrical heat pipe tube;
- welding a first end of a fill tube to one of the end caps to provide a fluidic passage therethrough which provides access into an internal portion of the cylindrical heat pipe tube;
- fluidically connecting disconnecting valve means to a second end of the fill tube so as to provide easy and repeatable access to and resealing of an internal portion of the cylindrical heat pipe tube;
- evacuating and filling the cylindrical heat pipe tube using the disconnecting valve means; and
- spinning the cylindrical heat pipe tube about its longitudinal axis of symmetry and applying the spiral fins thereto as the cylindrical heat pipe tube spins.
