Research on efficient heat utilization of heated tobacco device based on heat flow analysis method.

The flow analysis method based on TRIZ theory identifies the effective flow and harmful flow in the heat transfer process of the heated tobacco device, and proposes an optimization scheme for reducing energy consumption of the heated tobacco device, such as the structure optimization of the containing tube, the simplification of the airway tube, and the adjustment of the temperature distribution of the heater, and the scientificalness and practicability of the method in the energy consumption control process of iRod was verified. The results showed that: under the same taste, iRod reduced energy consumption by 11. 1%, and increased the usage of 2 heated tobacco; at the same time, the temperature on the surface of the iRod was reduced by more than 3. 3 °C, the sense of touch is improved obviously.
