Abstract

An aerosol generating device, includes an inhalation outlet; a chamber for holding a material, the material capable of generating a vapour when heated; a heater for heating material held in the chamber; an air inlet connected by an air inlet passage to the chamber; a vapour-cooling module providing a fluidic connection between the chamber and inhalation outlet, the module configured to cool a vapour passing there through. Suction at the inhalation outlet causes air to enter the chamber via the air inlet, thereby transporting vapour generated in the chamber through the module to the inhalation outlet, such that the temperature of the vapour exiting the device through the inhalation outlet is substantially lower than the temperature of the vapour generated in the chamber. The device thereby provides a means whereby a vapour generated in the chamber is substantially cooled during transport from the chamber through the mouthpiece to the user.
