Abstract (en)
An aerosol delivery system (110) comprising an air inlet (172), an outlet (174), and an air passage (170) extending from the air inlet (172) to the outlet (174). A part of the air passage is defined by a heat source air passage (170a) extending through a heat source (200) operable to heat air in the heat source air passage (170a) through an exothermic reaction. A reservoir (160) formed from an air-permeable substrate is arranged to allow air in the air passage drawn from the outlet (174) of the air passage (170) to be drawn through the reservoir (160) and on to the outlet (174), the reservoir (160) being loaded with a source of nicotine. The heat source air passage (170a) has a heat source air inlet and a heat source air outlet, spaced apart on the heat source (200) by a separation distance. In use, the heat source air passage (170a) conveys air along a flow path within the heat source (200) from the heat source air inlet to the heat source air outlet, wherein the length of the flow path is greater than the separation distance.
