AEROSOL-GENERATING DEVICE COMPRISING MULTIPLE SOLID-LIQUID PHASE-CHANGE MATERIALS.

摘要

An aerosol-generating device (4) for use in an aerosol-generating system and an aerosol-generating system comprising an aerosol-generating device (4) and an aerosol-generating article (2). The aerosol-generating device (4) comprises: a cavity configured to receive an aerosol-generating article (2); a first solid-liquid phase-change material (16) positioned about a perimeter of the cavity; and heating means (14) configured to heat the first solid-liquid phase-change material (16) to a temperature above the melting point of the first solid-liquid phase-change material (16). The aerosol-generating device (4) further comprises: a second solid-liquid phase-change material (18), wherein the melting point of the second solid-liquid phase-change material (18) is higher than the melting point of the first solid-liquid phase-change material (16).
