ABSTRACT:
Through employment of a core-and-sheath construction having a number of axially elongated indentations along the border for the billet with the core of an easily soluble material, extrusion such as hydrostatic extrusion can advantageously be utilized for production of heat pipes with enhanced precision and operational efficiency in process. Indentations, which work as a wick in the heat pipe, may be provided by forming axially elongated grooves either in the inner peripheral surface of the sheath or in the outer peripheral surface of the core.
