Abstract (en)

[origin: WO2021170832A1] An aerosol generating device (1) is described. The aerosol generating device includes: a housing (10); a tubular heating chamber (20) arranged to receive an aerosol substrate, the heating chamber operable to heat the aerosol substrate to generate an aerosol; an elongate battery (30); a frame (60) within the housing, the frame arranged to hold the battery and heating chamber within the frame such that the heating chamber and the battery are aligned end-on within the housing with a first end (21) of the tubular heating chamber facing a first end (31) of the battery; wherein the frame comprises a dividing wall (61) arranged between the first end of the battery and the adjacent first end of the heating chamber. By providing a tubular heating chamber and an elongate battery which are aligned end-on within the housing, the surface area of the thermal interface between the heating chamber and battery is significantly reduced, thereby reducing heat transfer to the battery. This further allows for a more compact, user-friendly arrangement but without increasing heat transfer to the battery, as would usually be associated with reducing the size of the device.
