Claim:
1. An aerosol generating system, comprising: an aerosol-forming article, comprising an aerosol-forming substrate and a mouthpiece portion for allowing a user to draw air through the substrate; an aerosol generating device, comprising a housing having proximal and distal ends and comprising at least one external surface and one internal surface, the internal surface defining an open ended cavity at the proximal end of the housing in which the aerosol-forming substrate is received, the cavity having a longitudinal extent between its proximal and distal ends, a heater element within the cavity configured to heat an aerosol-forming substrate received in the cavity, and an air inlet; a first air flow channel extending from the air inlet to a distal end of the cavity, wherein the first air flow channel extends between the heater element and the external surface of the housing along at least a portion of the longitudinal extent of the cavity; and a second air flow channel extending from the distal end of the cavity to the mouthpiece portion, wherein the heater element is in the form of a pin or blade that extends into the substrate, and wherein a distal end of the first air flow channel and a distal end of the second air flow channel meet at an air outlet positioned around a base of the heater element.
