Abstract
A heater arrangement for an aerosol generating device includes a tubular heating chamber including a cavity arranged to receive an aerosol generating substrate, a layer of insulation wrapped so as to circumferentially surround the heating chamber and an insulation support assembly including a rigid surround arranged around the heating chamber; wherein the insulation support assembly is arranged to engage the heating chamber and the insulation layer to hold the insulation layer in position around the heating chamber. Devices utilising such a heating arrangement display improved thermal insulation performance and allow for greater freedom in selecting insulating materials. The heater arrangement is also lower cost compared to conventional insulated heaters, for example those utilising vacuum tubes, as well as being lower weight. The insulation support assembly reduces heat transfer from the heater and also improves ease of assembly.
