Abstract
An aerosol-generating device is provided, for use in an aerosol-generating system and an aerosol-generating system including an aerosol-generating device and an aerosol-generating article. The aerosol-generating device includes a cavity configured to receive an aerosol-generating article; a first solid-liquid phase-change material positioned about a perimeter of the cavity; and heating means configured to heat the first solid-liquid phase-change material to a temperature above the melting point of the first solid-liquid phase-change material. The aerosol-generating device further includes a second solid-liquid phase-change material, wherein the melting point of the second solid-liquid phase-change material is higher than the melting point of the first solid-liquid phase-change material.
