An aerosol-generating article is provided, including a plurality of elements assembled in the form of a rod, the elements including an aerosol-forming substrate and an aerosol-cooling element located downstream from the aerosol-forming substrate. The aerosol-cooling element includes 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 about 300 mm.sup.2 per mm length and about 1000 mm.sup.2 per mm length. An aerosol passing through the aerosol-cooling element is cooled, and in some embodiments, water is condensed within the aerosol-cooling element.

The present disclosure provides an aerosol source member and an aerosol delivery device that includes an aerosol source member. The aerosol source member includes a segmented substrate portion that includes a first substrate segment and a second substrate segment. The first substrate segment includes a first aerosol former, the second substrate segment includes a second aerosol former different from the first aerosol former, and the second substrate segment is positioned between the first substrate segment and a downstream end of the aerosol source member. The first substrate segment and the second substrate segment are configured such that when heated by a heat source, the first substrate segment is heated to a first temperature and the second substrate segment is heated to a second temperature that is less than the first temperature.

A smokeless flavor inhalator includes a tobacco material as a flavor generator, and a heater for heating the tobacco material to allow flavor components to be released from the tobacco material while preventing smoke from being generated from the tobacco material. The heater has a carbon heat source and a cooling element. The carbon heat source and the cooling element cooperatively keep the heating temperature of the tobacco material at a temperature of 50 to 200° C.

A holder (200) for an aerosol generating article (100) includes a body (210) defining a passage configured to receive the article. The holder also includes a retainer (240) longitudinally moveable relative to the body from a first position to a second position. The retainer comprises a deflectable arm (242) and a retention member (247) extending from the arm and configured to retain the article within the passage of the body when the retainer is in the first position. Movement of the retainer to the second position causes the arm to deflect to provide access for introducing or withdrawing the article from the passage of the body. The holder may include a plurality of retainers moveable from a first position to the second position. The plurality of retainers may surround a combustible heat source (102) of the aerosol generating article when the retainers are in the first position.
