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 aerosol-generating system is provided, including an air inlet and an air outlet; a liquid storage portion having a liquid outlet and being configured to hold a liquid aerosol-forming substrate; an air flow passage from the air inlet to the air outlet past the liquid outlet, wherein the air flow passage is shaped such that there is a pressure drop within the air flow passage at the liquid outlet when air flows from the air inlet to the air outlet through the air flow passage; and a heating element disposed within the air flow passage between the liquid outlet and the air outlet. There is also provide a cartridge for an aerosol-generating system and a method of generating aerosol from a liquid aerosol-forming substrate.
