Abstract

Heat pipes containing graded pore non-arterial wicks have substantially improved reliability when compared with those which utilize arteries. Heat pipes having wicks which are optimally graded in pore size in an axial direction, with the pore size decreasing from the condenser to the evaporator end. These graded pore size wicks yield more than twice the capacity of axially uniform pore size wicks having similar geometries.
