Patent ID: 7669838

Claim:
An air handling heat exchanging humidifying apparatus comprising; an external outer case and mounted within said case a heat exchanger humidifying cell, said cell having a self supporting sheet like body with a multitude of air openings therethrough that are created by cutting parallel rows of slits into the sheet like body, and then expanding the sheet like body by pulling two opposing edges of the sheet like body that are perpendicular to rows of slits, the sheet like body then being formed to have a corrugated or saw tooth profile with the multitude of air openings being arranged in faces of the corrugated or saw tooth profile, the body defining arm surfaces around the openings on which a humidifying liquid can be deposited, cell mounting means mounting said cell in said case so the body is in a generally horizontally extending self supporting plane, humidifying liquid distribution means in said case above said cell for distributing humidifying liquid so it will be deposited onto the top of the cell and to said surfaces, a humidifying liquid cooler in said case and mounted directly adjacent said cell for cooling the humidifying liquid immediately before being deposited onto said surfaces, an air mover for moving air in a direction upwardly through the openings of the cell where humidifying liquid on said surfaces can be collected by the passage of air, and an air outlet for permitting air and any collected humidifying liquid moved by said air mover to be discharged from said apparatus.
