Abstract:
1. An apparatus comprising: a first surface extending at least in first and second directions mutually orthogonal to one another; a plurality of second surfaces extending from the first surface to form channels, the first surface forming a bottom surface of each thereof; a working fluid passing continuously and substantially isotropically by capillary action in the first and second directions among the channels; and the first and second surfaces connecting at vertices, the first and second surfaces and vertices being sized relative to one another to support substantially continuous, isotropic, capillary action along the first surface without a wick; wherein the working fluid operates in first and second phases to: deliver heat to the second location while transitioning from the second phase to the first phase; and return by capillary action through the channels, without a wick, to the first location.
