Title: AEROSOL-GENERATING ARTICLE HAVING AN AEROSOL-COOLING ELEMENT
Abstract:
An aerosol-generating article (10) comprises a plurality of elements assembled in the form of a rod (11). The elements include an aerosol-forming substrate (20) and an aerosol-cooling element (40) located downstream from the aerosol-forming substrate (20). The aerosol-cooling element (40) comprises a plurality of longitudinally extending channels and has a porosity of between 50% and 90% in the longitudinal direction. The aerosol-cooling element may have a total surface area of between 300 mm2 per mm length and 1000 mm2 per mm length. An aerosol passing through the aerosol-cooling element (40) is cooled, and in some embodiments, water is condensed within the aerosol-cooling element (40).
