A water separator consisting of a baffle and scupper is inserted inside the outlet header of a regenerative heat exchanger for removing water from the air discharged therefrom. The cooled air which contains water droplets leaving the core of the heat exchanger is passed through a baffle constructed to provide a gradual restriction in area in order to increase flow velocity. Heavy droplets of water are separated by the sudden change in airflow direction through the baffle and header. The flow including the heavier centrifuged water droplets then impinge on the inside surface of the header to which the accumulated particles of water adhere and are accelerated by the airflow and the contour of the header toward a scupper located downstream of the baffle opening. The water is collected in the scupper cavity, collected in a drain well, and drained with the assistance of gravity and the resulting pressure differential across the drain port. The scupper contains holes or louvered slots whereby some air used to carry the water along the header inner surface may pass therethrough to combine with the remaining airflow in the duct through which the dried air is removed from the system.

A water collection and disposal system adapted to remove moisture from an airstream emanating from a heat exchanger core or the like comprising: baffle means connected along a substantial portion of the outside edge of said core, said baffle means extending a short distance in the direction of the outlet airstream from said core and simultaneously being contoured toward a selected side portion of said core forming thereby a gradual area restriction to the entire outlet airstream from said core for increasing the velocity thereof; a substantially semi-hemispherical header member having one open end with the remainder of said header completely covering said core and said baffle means, said header member being contoured in the area above which said airstream passes through the area restriction in said baffle means, said contour in said header member being such as to cause the airstream to be redirected within said header member away from the area of said header member where said airstream initially impinges, the increasing velocity and changing direction of said airstream centrifuging heavy droplets of water and causing the accumulated water to flow along the inner surface of said header member in the direction of airstream flow; water collector means attached about the inside contour of said header member at the open end thereof, said water collector means extending a short distance below the inside of said header member and including a solid wall portion for blocking the airstream flow and also including a trough member connected to said solid wall portion for collecting the water in said airflow, said trough member being extended along the length of said header member and forming a drain cavity between said extended portion of said trough member and one side of said header member for accumulating the collected water; a drain tube connected to said header adjacent said drain cavity for draining said collected water; air passage means in said trough member; and air outlet duct means attached to the open end of said header member.
