Aerosol Generation Device Having A Thermal Bridge

Abstract

An aerosol generation device has a heating chamber into which an aerosol substrate is insertable for being heated to generate an aerosol. The heating chamber is housed in a casing and an aperture is provided, through which the aerosol substrate is insertable into the heating chamber, e.g. through an open end of the heating chamber. Insulation is disposed between the heating chamber and the casing and a thermal bridge is arranged to dissipate heat from the heating chamber to the casing, for example in the vicinity of the aperture or from the open end of the heating chamber.
