Annular Heat Pipe Cooling for Multi-Gap Ozone Generators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozone generators with multiple discharge gaps face inefficiencies in cooling systems, leading to excessive heat buildup and reduced ozone concentration due to inadequate heat removal from the discharge gaps and components.
Innovation Solution
The device employs an electrode arrangement with annular heat pipes acting as closed heat exchange systems, surrounding high-voltage and ground electrodes, allowing for efficient cooling of discharge gaps without the need for additional cooling media or systems, and enabling the design to be compact and 'plug and play' by placing the cooling section in proximity to the discharge gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water is arranged to directly cool the outer electrode, then cooling effect is achieved, but cooling efficiency is insufficient for multiple-gap arrangements
Solution Approach 1:
The invention extracts the cooling function from the outer electrode structure by introducing a separate inner electrode that serves as a dedicated heat dissipation element. This inner electrode is thermally coupled to the outer electrode through thermal conductive material, allowing heat to be extracted from the discharge gap region without compromising the outer electrode's electrical function or requiring direct water cooling of the outer electrode itself.
Solution Approach 2:
The invention introduces thermal conductive material as an intermediary between the inner and outer electrodes. This intermediary substance facilitates efficient heat transfer from the outer electrode to the inner electrode, enabling effective heat dissipation while maintaining the structural integrity and electrical insulation requirements of the electrode assembly.
2Productivity
If multiple discharge gaps are used, then ozone generation efficiency is improved, but heat build-up increases
Solution Approach 1:
The invention segments the heat dissipation function by introducing a separate inner electrode structure that is dedicated to heat removal. This segmentation allows the outer electrode to focus on electrical discharge generation while the inner electrode handles thermal management, enabling multiple discharge gaps to operate at higher efficiency without excessive heat accumulation.
Solution Approach 2:
The inner electrode structure serves itself dual functions: it acts as both an electrical component (forming discharge gaps with the outer electrode) and a thermal management component (dissipating heat from the discharge region). This self-service approach integrates cooling functionality directly into the electrode structure without requiring external cooling systems.
3Volume of stationary object
If cooling section is placed in proximity to discharge gap, then system size is reduced, but cooling complexity increases
Solution Approach 1:
The invention merges the cooling section with the electrode structure by making the inner electrode itself the heat dissipation element. This merging eliminates the need for separate external cooling systems and reduces overall system size, as the cooling functionality is integrated directly into the electrode assembly rather than being added as a separate component.
Solution Approach 2:
The inner electrode structure performs multiple functions simultaneously: it forms discharge gaps for ozone generation, provides electrical insulation where needed, and serves as the primary heat dissipation element. This multi-functionality reduces the number of separate components needed and simplifies the overall cooling system architecture.
