Solution Overview
Problem
Existing Heat Not Burning (HNB) aerosol generating articles have a low heat dissipation rate and poor cooling effect, leading to a suboptimal user experience due to inadequate temperature reduction of the aerosol.
Innovation Solution
The aerosol generating article incorporates a cooling section with heat conduction members on its outer and/or inner surfaces, increasing the surface area for enhanced energy exchange and heat dissipation, thereby improving the cooling effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling section is used to reduce aerosol temperature, then the aerosol temperature can be reduced to a suitable level, but the heat dissipation rate is low and the cooling effect is poor
Solution Approach 1:
The patent applies dimensionality change by adding heat conduction members that extend in the axial direction of the cooling section, transforming the two-dimensional surface cooling into a three-dimensional heat dissipation structure. This increases the effective heat exchange surface area from just the outer surface to include both outer and inner surfaces, thereby significantly improving the heat dissipation rate while maintaining the cooling function.
2Temperature
If the cooling section uses solid heat transfer, then the aerosol temperature can be reduced, but the heat dissipation rate is low resulting in poor cooling effect
Solution Approach 1:
The cooling section is segmented into multiple functional surfaces by adding heat conduction members. The cooling function is divided between the outer surface (for environmental heat exchange) and the inner surface (for aerosol contact), with heat conduction members serving as thermal bridges. This segmentation allows heat to be dissipated through multiple pathways simultaneously, improving overall heat dissipation efficiency.
Solution Approach 2:
The cooling section employs a composite structure combining the body material with heat conduction members made of high-thermal-conductivity materials. This composite design creates a multi-layered heat dissipation system where the heat conduction members act as thermal conduits, enhancing the overall heat transfer efficiency from the aerosol to the external environment.
