1. A nicotine e-vaping section, comprising:
a housing;
a wick in a chamber defined within the housing, the wick contacting a first outer surface of a first wall that faces an interior of the chamber;
an airflow path defined within the housing, the airflow path fluidly connecting the chamber to an outlet of the nicotine e-vaping section;
a heater in heating proximity to the wick; and
a reservoir configured to contain a nicotine pre-vapor formulation, the nicotine pre-vapor formulation including nicotine,
the first wall defining an entrenched section that at least partially contains the wick, the first wall at least partially defining at least one first channel that traverses through the first outer surface, the at least one first channel being configured to communicate the nicotine pre-vapor formulation from the reservoir to the wick, and
the first wall at least partially defining one or more air passages that traverse through the first outer surface, the one or more air passages being configured to allow air to enter the reservoir, the at least one first channel and the one or more air passages running parallel to each other and being configured to respectively communicate the nicotine pre-vapor formulation and the air in opposing directions through the first wall, the one or more air passages having a first length that is longer than a second length of the at least one first channel,
an entrance of a first air passage, of the one or more air passages, being within the airflow path and between the heater and the outlet, the heater being configured to at least partially vaporize the nicotine pre-vapor formulation that is communicated to the wick, the outlet being configured to allow the vapor from the chamber to be drawn through the airflow path and out of the nicotine e-vaping section, the chamber, the heater and the entrance being configured to allow a portion of the vapor to enter the reservoir through the first air passage.
