Abstract
A water vapor transfer unit having fluid flow conduits which distribute wet or dry fluid throughout the water vapor transfer unit, which are created by forming apertures in each wet and dry plate so that when the plates are stacked, fluid flow inlet and outlet headers are integrated into the flow stack. These integrated headers negate the need for traditional wet and dry fluid inlet and outlet manifolds external to the water vapor transfer unit stack. Because the plates are stacked and sealed so that the fluid flows cannot co-mingle, the fluids are introduced directly into the stack, flow across the flow fields, and exit the stack without leakage or flow contamination. The integrated header design allows for sealing the stack on no more than a single plane defined by the stack or on no more than two parallel opposing planes and allows for accommodation of stack expansion and contraction.
