Abstract
Multi-stage microchannel heat and/or wherein said heat and/or mass transfer system includes a system selected from a group of heat exchanger, mass transfer system, and combination thereof, mass transfer system attains an enhanced heat transfer, low pressure drop, and optimized flow distribution and stability for a single- and two-phase applications by combining microchannels formed on industrially available fin tubes, and a multi-stage flow distributing manifold, and directing the flow of a heat exchanging medium through multiple passes formed by short length of respective microchannels, while controllably by-passing some microchannels when migrating the flow of the heat exchanging medium from the microchannels into multiple mixing stages provided by a specific configuration of the manifold. Multiple stages of variable length correlated with the mixing zones are provided in the flow distributing manifold to enhance operational parameters of the system for different applications including evaporators, condensers, and gas-liquid absorbers.
