Heating-Type Flavor Inhaler Casing Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heating-type flavor inhalers, the heat generated by the heater tends to accumulate in the casing, potentially damaging components and affecting the flavor generating source.
Innovation Solution
A bumpy metal pattern is applied to the outer surface of the casing, particularly where the heater is located, to enhance heat dissipation, increasing the surface area and using protrusions with a tapered shape and heat-insulating material to facilitate efficient heat release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heater is used to electrically heat the flavor generating source in the casing, then the flavor generating source can be heated without burning or thermal decomposition, but heat accumulates in the casing and adversely affects the parts and flavor generating source
Solution Approach 1:
The patent applies a bumpy pattern to the outer circumferential surface of the casing, transforming a two-dimensional flat surface into a three-dimensional textured surface. This dimensional change increases the surface area for heat dissipation, allowing heat to escape more efficiently from the casing without affecting the internal heating function.
Solution Approach 2:
The bumpy pattern is applied specifically to the outer circumferential surface of the casing where heat dissipation is needed, while the internal structure and heating components remain unchanged. This localized application of the bumpy pattern targets the specific problem of heat accumulation without altering the essential heating function.
2Ease of manufacture
If the casing surface is made smooth and simple, then manufacturing is easier and cost is lower, but heat dissipation efficiency is reduced
Solution Approach 1:
By adding vertical dimensionality through protrusions and recesses on the casing surface, the patent increases heat dissipation capacity without fundamentally changing the manufacturing process. The bumpy pattern can be integrated into existing molding or fabrication techniques, maintaining ease of manufacture while improving thermal performance.
