Abstract (en)
A heat transfer assembly for heating an aerosol generating medium, such as a cigarette, without burning. The heat transfer assembly comprises a heat absorber, a heat modulator, and a heat diffuser. The heat absorber is configured to absorb thermal energy from a proximate heat source in a first temperature range. The heat absorber is thermally coupled to the heat modulator, and the heat modulator is thermally coupled to the heat diffuser. The heat modulator is configured to absorb the thermal energy emitted from the heat source, and to provide thermal energy to the heat diffuser in a second temperature range different to the first temperature range, wherein the lowest temperature of the first temperature range is greater than the highest temperature of the second temperature range. The heat modulator comprises at least one phase change material.
