A heater may include: a conductive ceramic cylinder tube in which cell-arrays are concentrically arranged, each cell-array including cells which are arranged in a circumferential direction of the ceramic cylinder tube; an inner electrode electrically coupled to an inner wall portion of the ceramic cylinder tube; and an outer electrode electrically coupled to an outer wall portion of the ceramic cylinder tube. Non-linear portions are radially arranged in the ceramic cylinder tube, each non-linear portion extending in a radial direction of the ceramic cylinder tube while having a plurality of bends or curves between the inner wall portion and outer wall portion of the ceramic cylinder tube. The inner and outer electrodes are provided such that current flows radially at least via said non-linear portions between the inner and outer electrodes.

A handheld evaporation apparatus having an evaporating heating element and a housing that encases the evaporating heating element. The evaporating heating element is adapted to achieve a temperature ranging from 250 to 2000 degrees Fahrenheit by heating and differential material composition. The housing includes a first end having an opening that allows heated air provided by the evaporating heating element to exit out through the first end. The housing further includes one or more air ducts on an outer surface of the housing, where the one or more air ducts allow ambient air outside the housing to enter into the housing and flow past the evaporating heating element so as to be heated by the evaporating heating element. In one example, the housing's first end has a semi-ovoid shape that presses against and seals a hemispherical-shaped case. In another example, the housing's first end includes an elastic band that surrounds the opening and presses against the inner surface of the bowl to create a substantially airtight seal.

A method of manufacturing a gas heater heating element including a support and channel structure with a plurality of channels formed in the monolith includes shaping an electric heating element and at least partially coating the electric heating element with at least one coating material. The at least partially coated electric heating element is positioned in a mold for producing the monolith. The monolith is produced and surrounds the at least partially coated electric heating element. The coating material of the at least partially coated electric heating element is removed. The gas heater heating element includes at least one electric heating element in the monolith and the electric heating element is guided in the plurality of channels of the support. Heat within the plurality of channels is configured to be transferred by the electric heating element to a gas flowing through the plurality of channels to heat the gas.

The present invention relates to a heater assembly for an aerosol generating device. The heater assembly includes a tubular heating chamber and a flexible thin film heater comprising a heating element track supported on a surface of a flexible electrically insulating backing film; wherein the flexible thin film heater is wrapped around an outer surface of the heating chamber with the backing film toward the heating chamber. The invention further includes a temperature sensor comprising a temperature sensing element configured to sense a local temperature, wherein the temperature sensing element is positioned so as to overlap with a portion of heating element track. Because the temperature sensing element overlaps with a portion of the heating element track, the temperature sensor provides a more accurate reading of the temperature of the heating element itself.
