Abstract
A corrosion resistant heat pipe construction which prevents the formation of corrosive oxides of sodium which may result when a sodium heat transport medium combines with oxygen within the heat pipe. In accordance with this invention, formation of such corrosive compounds is inhibited through the introduction of zirconium in the form of a fine thread woven into the heat pipe wick. When the wick is installed within the heat pipe, the zirconium will react with oxygen to form a relatively non-corrosive zirconium oxide. By introducing the zirconium thread into the wick material matrix, the fabrication of the heat pipe is carried out in accordance with present techniques, without requiring the addition of other components or operations.
