Heating Element Microgroove Structure for Vaporization Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic vaporization devices experience large temperature field fluctuations and bubble formation randomness during the boiling process due to the heating wire's instability, affecting the vaporization efficiency and aerosol formation.
Innovation Solution
A heating element with a microgroove portion is introduced, connected to a liquid absorbing element, where the microgroove facilitates nucleation site formation and reduces heat flux, allowing bubbles to grow and separate uniformly, thereby controlling the boiling process and aerosol formation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating wire is used to heat to-be-vaporized liquid, then the liquid can be vaporized, but large temperature field fluctuations and bubble formation randomness occur due to high instability during boiling
Solution Approach 1:
The heating element surface is divided into multiple local regions with different properties: microgroove portions that serve as stable nucleation sites and non-microgroove portions. This local differentiation ensures bubbles form at predetermined positions rather than randomly, stabilizing the temperature field and boiling process
2Reliability
If a heating wire heats to-be-vaporized liquid, then vaporization occurs, but the generation positions of bubbles are random and unstable
Solution Approach 1:
The heating element surface is segmented into multiple microgroove portions distributed across the surface. Each microgroove portion acts as an independent nucleation site, dividing the bubble generation process into multiple controlled locations rather than random single-point formation, thereby stabilizing bubble distribution
3Reliability
If microgroove portions are added to the heating element, then nucleation site formation is enhanced and bubble distribution is uniform, but the device structure becomes more complex
Solution Approach 1:
The heating element incorporates microgroove portions that create a controlled porous-like structure on the surface. This structure provides multiple nucleation sites for bubble formation without requiring complex internal mechanisms, achieving stable vaporization through surface geometry modification rather than complex device architecture
