Abstract
Effective two-phase cooling is provided to large devices even with a length of ˜10 cm due to a channel configuration to achieve formed minichannels comprising porous wall structures. Baseplate features comprise a substrate defining the minichannels, with each minichannel formed between a pair of side walls and a bottom surface thereof. The side walls of the plurality of minichannels respectively form terminal walls for each of the respective minichannels. A microgap configuration is formed between the terminal wall of at least one of the plurality of minichannels and an adjacent layer.
