Within the passage is a Peltier effect device that has a cold surface exposed to air flowing within the passage and a hot surface connected to a heat radiator. Water vapor carried in air that contacts the cold surface condenses; there is sump below the cold surface to contain water that condenses. The housing is installed so that air flow through the passage is induced by convection.
