Abstract
A heater for heating an aerosol-forming substrate includes a plurality of elongate heating elements arranged in an elongate array. The elongate array has a support end with a first dimension, a heating end with a second dimension and a middle portion with a third dimension. The array is arranged to heat the substrate to form an aerosol. The third dimension is greater than the first dimension and greater than the second dimension. An electrically heated aerosol generating system can include the heater.
Claims19
A method, comprising:
- flat stamping a heating element material to form heating elements, each of the heating elements including a first end and a second end that is opposite to the first end, the first end of each of the heating elements being connected to a linking element so that the heating elements are electrically and mechanically connected together, the linking element being substantially straight, respective portions of the heating elements being substantially parallel to each other;
- bending the linking element into a substantially circular shape;
- coupling opposing ends of the linking element together;
- coupling the second end of the heating elements to a collar element to establish an electrical connection between the heating elements and the collar element;
- and
- electrically coupling the collar element to a voltage source.

A method, comprising:
- flat stamping a heating element material to form heating elements, each of the heating elements including a first end and a second end that is opposite to the first end, respective portions of the heating elements being substantially parallel to each other;
- and
- first coupling the second end of each of the heating elements to a voltage source, the first coupling causing the heating elements to be mechanically and electrically connected to each other, the first end of each of the heating elements being connected by a linking element.
