Heater assembly for an aerosol-generating system

A heater assembly for an aerosol-generating system, the heater assembly comprising:

• an electrical heating element configured to heat a liquid aerosol-forming substrate to form an aerosol;
• a capillary body having a porous end surface and being configured to convey the liquid aerosol-forming substrate to the electrical heating element, wherein the electrical heating element is disposed along and physically contacts the porous end surface;
• and
• two electrical contacts connected to the electrical heating element, the electrical contacts being disposed at opposite sides of the porous end surface.

An aerosol-generating system, comprising:

• an aerosol-generating device comprising a power source, and
• a cartridge removably coupled to the aerosol-generating device, the cartridge comprising:
• a liquid storage portion configured to hold a liquid aerosol-forming substrate;
• and
• a heater assembly comprising:
• an electrical heating element configured to heat the liquid aerosol-forming substrate to form an aerosol;
• and
• a capillary body having a porous end surface and being configured to convey the liquid aerosol-forming substrate to the electrical heating element,
• wherein the electrical heating element is disposed along and physically contacts the porous end surface, and
• wherein the liquid storage portion is disposed at a first side of the heater assembly and an airflow channel is disposed at an opposite side of the heater assembly to the first side and adjacent to the electrical heating element, defining an airflow path that extends past the electrical heating element and is configured to convey the aerosol,
• wherein the power source of the aerosol-generating device is configured to supply power to the heater assembly.
