Aerosol-generating device with heater with cold zone

Abstract

A heater assembly for an aerosol-generating device is provided, including: an elongate heating chamber configured to heat an aerosol-forming substrate; and a heating element arranged around the elongate heating chamber, the elongate heating chamber having a first length and the heating element having a second length, the first length of the elongate heating chamber being greater than the second length of the heating element, such that there is a proximal distance between a proximal end of the elongate heating chamber and a proximal end of the heating element, and the proximal distance being between 0.1 millimeter and 4 millimeters. An aerosol-generating device including the heater assembly, and an aerosol-generating system including the aerosol-generating device and an aerosol-generating article, are also provided.
