Abstract:
1. A method for making a heat pipe wick on an inside surface of a heat pipe container, comprising the steps of: (a) positioning a mandrel having a grooved contour within a portion of said container; (b) providing a slurry of metal particles having an average particle diameter and that are suspended in a viscous binder; (c) coating at least part of the inside surface of said container with said slurry so that said slurry conforms to said grooved contour of said mandrel and forms a layer of slurry between adjacent grooves that comprises no more than about six average particle diameters; wherein six of said average particle diameters is within a range from about 0.05 millimeters to about 0.25 millimeters; (d) drying said slurry to form a green wick; and, (e) heat treating said green wick to yield a final composition of the heat pipe wick.
