Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air circulating devices with heat exchange elements lack an effective structure for dust removal, leading to inefficiencies in ventilation due to the need for high-performance filters that reduce airflow.
Innovation Solution
The air circulating device incorporates a heat exchange element with conductive heat transfer plates and spacers electrically connected to a charge generator, allowing for the electrostatic attraction and collection of fine dust, which can then be removed through a reverse washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-performance filters or multiple filters are installed to remove fine dust, then dust removal capability is improved, but air flow deteriorates and ventilation efficiency is reduced
Solution Approach 1:
The patent replaces the mechanical filtration system with an electrostatic precipitation system. Instead of using physical filters that mechanically block dust particles, the invention uses charged electrodes to electrostatically attract and collect fine dust particles from the air stream, thereby maintaining air flow while achieving effective dust removal
Solution Approach 2:
The invention changes the physical state of the heat exchange element by applying electrical charge to it. The heat transfer plates or spacers are electrically connected to electrodes that generate positive or negative charges, transforming the neutral heat exchange component into an active dust collection surface through electrostatic attraction
2Use of energy by moving object
If conventional heat exchange elements are used without dust removal means, then heat exchange efficiency is maintained, but dust accumulates and reduces overall system efficiency
Solution Approach 1:
The patent makes the heat exchange element multi-functional by integrating dust collection capability into it. The heat transfer plates or spacers serve dual purposes: facilitating heat exchange between indoor and outdoor air and simultaneously collecting fine dust through electrostatic attraction, eliminating the need for separate filtration components
Solution Approach 2:
The invention merges the heat exchange function and dust collection function into a single integrated component. The charged heat transfer plates or spacers combine thermal transfer and electrostatic precipitation functions, allowing both heat exchange and dust removal to occur simultaneously within the same structure
