Abstract: The split airflow system for an electrically heated smoking system for generating aerosol, the split airflow system having a downstream end comprises a first channel defining a first flow route and a second channel defining a second flow route. The first flow route directs ambient air from outside the system to the downstream end of the system. The second flow route directs ambient air from outside the system towards a preferably substantially flat, fluid permeable, heating element before conveying the ambient air to the downstream end. The first channel and the second channel define a total volume of ambient air passing through the system and the first channel provides at least 50 percent of the total volume of ambient air passing through the system. The invention also refers to a method for guiding an airflow in an electrically heated smoking system for generating aerosol and an electrically heated smoking system comprising the split airflow system.
