Abstract
A passive tortuous path drain for a directing fluid flow from an enclosure includes a drain body having a front face and a back face. The front face defines a curved trenched channel having a first curved channel end and a second curved channel end. The front face also defines a second trenched channel. The drain body defines at least one egress opening in fluid communication with the second trenched channel. The first curved channel end and a second curved channel end are in fluid communication with the second trenched channel. Characteristically, the drain is adapted to be positioned adjacent to a drain opening in an enclosure such that liquid flows from the drain opening to the curved trenched channel and then to the second trenched channel exiting through the egress opening.
