Abstract: An aerosol-generating system comprises a liquid storage portion comprising a container holding a liquid aerosol-forming substrate and defining an opening, and a heater assembly which extends across the opening along a transverse plane. The heater assembly comprises at least one electrically operated heating element, and a first channel defines a first flow route which brings ambient air into impingement against the heater assembly. In an embodiment a portion of the first channel is arranged orthogonally to the transverse plane such that the at least a portion of the first channel directs ambient air from outside the system to impinge perpendicularly onto a surface portion of the heating element before conveying the ambient air to a downstream end.

Abstract: An inductive heating device heats an aerosol-forming substrate including a susceptor. The device includes a device housing, a DC power source for providing a DC supply voltage and a DC current, power supply electronics including a DC/AC converter, the DC/AC converter including an LC load network including a series connection of a capacitor and an inductor having an ohmic resistance, a cavity in the device housing for accommodating a portion of the aerosol-forming substrate to inductively couple the inductor of the LC load network to the susceptor. The inductor is embedded in the device housing at a proximal end of the device housing to surround the cavity which is also arranged at the proximal end of the device housing. A microcontroller determines from the DC supply voltage and the DC current an apparent ohmic resistance, and from the apparent ohmic resistance the temperature of the susceptor.
