An aerosol generation device (100) has a heating chamber (108) for receiving a substrate carrier (114) containing an aerosol substrate (128). The heating chamber (108) comprises a first open end (110); a base (112); and a side wall (126) between the open end (110) and the base (112). The base (112) is connected to the side wall (126) and provides structural support to the side wall (126). The side wall (126) has a first thickness and the base (112) has a second thickness greater than the first thickness.一種氣溶膠產生裝置(100)具有加熱腔體(108),該加熱腔體用於接納包含氣溶膠基質(128)的基質載體(114)。該加熱腔體(108)包括第一開口端(110);基部(112);以及在該開口端(110)與該基部(112)之間的側壁(126)。該基部(112)連接至該側壁(126)並且對該側壁(126)提供結構支撐。該側壁(126)具有第一厚度,並且該基部(112)具有大於該第一厚度的第二厚度。
