Patent ID: 8356657

Claim:
A lattice wick apparatus, comprising: a plurality of granular wicking walls having respective lengths, widths and heights and configured to transport liquid through capillary action in a first direction along the respective lengths, the respective lengths being longer than the respective widths and the respective heights, each of said plurality of granular wicking walls being adjacent to one another and spaced apart to form respective vapor vents between them to transport vapor; and a plurality of granular interconnect wicks embedded between respective pairs of said plurality of granular wicking walls in a second direction substantially perpendicular to the first direction, said plurality of granular interconnect wicks having substantially the same heights as said plurality of granular wicking walls and forming a planar lattice wick surface with said plurality of granular wicking walls; wherein said planar wick surface is along a plane encompassed by the respective lengths and the respective widths and forms an outer surface of said plurality of granular wicking walls and of said plurality of granular interconnect wicks.
