Aerosol-generating article comprising a mouth-end cooling element

An aerosol-generating article for producing an aerosol upon heating, the aerosol-generating article comprising:

• a rod of aerosol-generating substrate comprising an aerosol former, the aerosol-generating substrate having an aerosol former content of greater than 10 percent on a dry weight basis;
• a hollow tubular support element positioned immediately downstream of the rod of aerosol-generating substrate;
• and
• an aerosol-cooling element downstream of the hollow tubular support element, the aerosol-cooling element extending all the way to a downstream end of the aerosol-generating article,
• wherein the aerosol-cooling element comprises a hollow tubular segment arranged immediately downstream of the hollow tubular support element, the hollow tubular segment having a transverse wall at a location between an upstream end and a downstream end of the hollow tubular segment, such that the hollow tubular segment defines a first cavity upstream of the transverse wall and a second cavity downstream of the transverse wall, and
• wherein the transverse wall comprises one or more openings establishing a fluid communication between the first cavity and the second cavity.
