ABSTRACT:
Input and output tubes in an osmotically pumped heat pipe (10) are utilized to improve solvent-solute mixing and sweeping across a solvent-permeable membrane (46, 146, 246), to enable its operation in 0-g, 1-g and negative-g applications. Lean mixture solution flows through a path (16) of low pressure to an evaporator (14) where the solvent evaporates. Rich mixture solution from the evaporator then returns to the solvent-permeable membrane through a path (18) of higher pressure than the low pressure path to enable sweeping of the membrane and consequent increased mixing with the incoming condensed solvent.
