1. A system for heating smokable material to volatilize at least one component of the smokable material comprising an apparatus arranged to heat smokable material and a consumable article containing smokable material, the apparatus comprising:
a housing, the housing having a first opening at a first end through which a consumable article containing smokable material can be removably inserted into the apparatus;
at least one heater arrangement arranged within the housing for heating smokable material within the consumable article when in use; and
a hollow chamber between the first opening and the at least one heater arrangement, the hollow chamber comprising an interior wall with a radially inner surface and a radially outer surface opposed to the radially inner surface, the radially inner surface surrounding at least a portion of the consumable article and the outer surface positioned interior to the housing,
wherein the radially inner surface of the interior wall and the at least a portion of the consumable article define one or more ventilation pathways there between, the one or more ventilation pathways extending from the first opening to the heater arrangement, the one or more ventilation pathways being radially between the radially inner surface of the interior wall and an exterior surface of the consumable article for the one or more ventilation pathways extending from the first opening to the heater arrangement, the one or more ventilation pathways being delimited by the exterior surface of the consumable article for the entire length of the one or more ventilation pathways extending from the first opening to the heater arrangement,
wherein, when the apparatus is in use, the one or more ventilation pathways allow air to flow in to the apparatus and along the exterior surface of the consumable article and the radially inner surface of the interior wall, the one or more ventilation pathways allowing air to contact the exterior surface of the consumable article along the entire length of the one or more ventilation pathways extending from the first opening to the heater arrangement, and
wherein the hollow chamber comprises one or more fins on the radially outer surface of the interior wall.
