Fluid permeable heater assembly for an aerosol-generating system and method for assembling a fluid permeable heater for an aerosol-generating system

Abstract

A cartridge for an aerosol-generating system is provided, including a liquid storage portion including a housing containing a liquid aerosol-forming substrate, the housing having an open end; and a heater assembly including: an electrical heating element configured to heat the substrate to form an aerosol, the heating element including a planar filament arrangement having one or more electrically conductive filaments, an electrically insulating substrate having a planar attachment face, the filament arrangement disposed on the planar attachment face, and clamping elements mechanically fixing the filament arrangement to the electrically insulating substrate and applying a pulling force onto the filament arrangement, at least a portion of the heater assembly being fluid-permeable, and the heater assembly being arranged over the open end of the housing.

Dependencies are inferred from the claim text.
