Abstract
The present invention provides an apparatus including a magnesium alloy vessel that is substantially free of aluminum and zinc, but including magnesium in combination with a gettering metal. The magnesium alloy vessel has a hollow interior cavity containing a working fluid, with a stable, protective layer formed on the inside wall of the vessel so as to establish non-corrosive compatibility with the working fluid.
Claims11
In a heat pipe including a magnesium alloy vessel substantially free of aluminum and zinc, said magnesium alloy vessel having a hollow interior cavity at least partially covered by a capillary wick structure, and containing a working fluid, the improvement comprising:
- forming a stable, protective layer on the inside wall of said magnesium alloy vessel, said protective layer establishing compatibility with said working fluid and preventing base metal corrosion by said working fluid at an interface between said capillary wick structure and said base metal, wherein said magnesium alloy vessel comprises magnesium in combination with an alloyed and/or dispersion strengthening, gettering metal.
In a heat pipe including a magnesium alloy vessel substantially free of aluminum and zinc, said magnesium alloy vessel defining a hollow interior cavity having a wall at least partially covered by a capillary wick structure, and containing a working fluid, the improvement comprising:
- forming a stable, protective layer on said wall of said magnesium alloy vessel, said protective layer establishing compatibility with said working fluid and preventing base metal corrosion by said working fluid at an interface between said wick structure and said base metal, wherein said magnesium alloy vessel comprises magnesium in combination with an alloyed and/or dispersion strengthening, gettering metal.
