1. A crank-shaped heat pipe for cooling rotating machinery, comprising:

  • (a) a cylindrical tube defining an inner wall, a condenser section, an evaporator section, and an adiabatic section,(b) a wick structure within said cylindrical tube,(c) a working fluid within said cylindrical tube for use as a heat transfer mechanism, and(d) said evaporator section or said adiabatic section defining a first curve and a second curve, said first curve and said second curve ranging from about 75 degrees to about 85 degrees, where said first and second curves reduce said working fluid instability and increase said heat transfer capability of said heat pipe, said wick structure including a first mesh screen and spacer wires, said first mesh screen separated from said inner wall by said spacer wires.
