摘要： A ceramic core has a hollow interior with a first, inner diameter. A coil with a second diameter is embedded in the ceramic core. At least a portion of the second diameter is smaller than the first, inner diameter of the ceramic core to expose at least a portion of the coil to the hollow interior of the ceramic core. The coil may be inlaid and fixed on the inner wall of the hollow interior, one end of the coil is fixedly connected to the first pin, the first pin embedded inside the ceramic core. The other end of the coil is fixedly connected to the second pin, the second pin embedded inside the ceramic core. The inner diameter of the coil is d, the inner diameter of the hollow interior is D, d is smaller than D, the wire diameter of the coil is xd, and xd cuts D.

摘要： A heater system includes an integrated heater device and a control system. The integrated heater device includes a thermocouple for measuring temperature and one or more multiportion resistive elements that are operable as heaters to create a temperature differential between the fluid and air to detect the fluid, and as sensors to measure a fluid level. The control device operates the integrated heater device as a sensor or heater based on one or more performance characteristics of the heater system and self-calibrates the heater device.

摘要： A heating apparatus for a fluid flow system having a container body includes a heater element and a strip. The heater element is within the container body and includes an electrical resistance element, a sheath, and an insulating material. The sheath extends along a predefined path through the container body and surrounds the electrical resistance element along the predefined path. The insulating material is disposed about the electrical resistance element between the electrical resistance element and the sheath. The insulating material electrically insulates the electrical resistance element from the sheath. The strip is disposed inside the container body and defines a tortuous geometry that follows the predefined path. The strip defines a plurality of openings at discrete locations along the strip. The heater element extends through the plurality of openings and is configured to contact the strip at the discrete locations.

摘要： A method of constructing a heating chamber for an aerosol generation device includes providing a side wall of the heating chamber, providing a heater, and arranging the heater to be in thermal contact with the side wall of the heating chamber. The method may also include attaching a heat shrink layer to the outward facing side of the heater, and heating the heat shrink layer to a temperature such that the heat shrink layer contracts to compress the heater against the side wall. The heating chamber for the aerosol generation device includes a side wall defining an interior volume of the heating chamber, and a heater in thermal contact with the side wall, as well as a heat shrink layer under tension, compressing the heater against an outwardly facing surface of the side wall.

摘要： A heater system includes a heater bundle. The heater bundle includes at least one heater assembly, where the heater assembly includes a plurality of heater units, and more than one of the heater units defines at least one independently controlled heating zone. The heater bundle includes a plurality of power conductors electrically connected to the independently controlled heating zone. The heater system includes means for determining temperature and at least one power switch, the power switch disposed proximate the heater bundle. The heater system includes at least one controller configured to modulate power to the independently controlled heating zones through the power conductors based on the determined temperature to provide a desired power output along a length of the heater assembly. The controller is configured to provide power to the power switch.
