A heater assembly for an aerosol-generating system is provided, the heater assembly including: a fluid-permeable heating element configured to vaporise a liquid aerosol-forming substrate; and a transport material configured to transport liquid aerosol-forming substrate to the fluid-permeable heating element, the transport material having a thickness defined between a first surface of the transport material and an opposing second surface of the transport material, the first surface being arranged in fluid communication with the fluid-permeable heating element and the second surface being arranged to receive liquid aerosol-forming substrate, the second surface of the transport material being provided with at least one hole that extends into the transport material to a depth corresponding to at least a part of the thickness of the transport material to define a formed fluid channel for the liquid aerosol-forming substrate, and the first surface of the transport material being convex.

Heater assembly with pierced transport material

A heater assembly for an aerosol-generating system is provided, including: a fluid-permeable heating element to vaporise a liquid aerosol-forming substrate; and a transport material to transport the substrate to the heating element and having a thickness defined between a first surface and an opposing second surface thereof, the first surface being in fluid communication with the element and the second surface being arranged to receive the substrate and provided with at least one hole extending into the material to a depth corresponding to at least a part of the thickness to define a formed fluid channel for the substrate, the material including a capillary material having elongate fibres, an average direction of the fibres is substantially parallel to the first and second surfaces, and the hole extends substantially perpendicular to the average direction. A method of manufacturing a heater assembly, a cartridge, and an aerosol-generating system are also provided.
