Abstract
A method of manufacturing a heat transfer device includes manipulating the microstructure of a metal alloy to thereby remove one or more chemical components of the alloy to form resultant heat pipe structure having an envelope composed of the precursor metal alloy and a porous wick structure composed of the dealloyed metal. Manipulation of the microstructure may be conducted by selective etching of a substrate composed of a metal or metal alloy using a dealloying process.
