Abstract: A cooling apparatus includes a flow equalizing manifold having hierarchical flow levels with descending and ascending passages dimensioned according to Bernoulli-based design relations to maintain substantially uniform flow conditions along prescribed streamlines. In certain embodiments, stepped or linear ceilings vary passage cross-section to regulate velocity/pressure at branch interfaces feeding a microchannel array. The manifold can implement forked symmetry or prescribed asymmetry, including different numbers/geometries/levels for inlets versus outlets and elevated vapor outlets for two-phase operation. In further embodiments, modular polygonal (hexagonal/diamond) flow units at a final level provide passive, spatially distributed flow metering/collection. The manifold and an associated finned plate may be additively manufactured and configured as modular, removably coupled components.

The manifold comprises hierarchical descending passages for liquid inflow and ascending passages for vapor and liquid outflow. Internal surfaces of vapor passages may include a hydrophobic composition and internal surfaces of liquid passages may comprise a hydrophilic composition to passively separate phases. The interface includes gas?permeable, liquid?resistant screens or barriers positioned at entrances of ascending vapor passages, and open areas aligned with descending and ascending liquid passages. A vapor outlet may be located at a higher elevation than a liquid outlet. The microchannel array can include divergent microchannels with regions coordinated to the interface.
