Air Conditioner Vane Insulator Segmentation to Reduce Dew Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing air-conditioners, dew formation occurs at the end portions of the blade due to temperature differences between the inner and outer surfaces, and the non-uniform space within these end portions makes it difficult to dispose insulators effectively.
Innovation Solution
The air-conditioner incorporates a vane with an insulator disposed between its guide and base panels, featuring a flat portion and inclined portions to guide airflow smoothly and reduce dew formation. The insulator is strategically placed to accommodate different materials for high insulation performance, even in non-uniform spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an insulator is not disposed at both end portions of the blade, then the structure is simpler, but dew formation occurs due to temperature difference between inner and outer surfaces
Solution Approach 1:
The insulator is divided into multiple segments: a first insulator disposed at the flat portion and a second insulator disposed at the inclined portion. This segmentation allows the insulator to cover different regions of the blade end portions, effectively reducing dew formation at both end portions while maintaining structural simplicity
Solution Approach 2:
Different insulator materials or properties are applied to different locations: the first insulator is disposed between the flat portion and base panel, while the second insulator is disposed between the inclined portion and base panel. This local differentiation addresses the specific dew formation issues at each end portion of the blade
2Adaptability or versatility
If a space formed inside both end portions of the blade is not uniform, then the blade structure is more functional, but it becomes difficult to dispose an insulator with low elasticity
Solution Approach 1:
The insulator arrangement adapts to the non-uniform internal space by placing the first insulator in the space between the flat portion and base panel, and the second insulator in the space between the inclined portion and base panel. This local adaptation allows low-elasticity insulators to be properly disposed in the varying spaces created by the functional blade structure
3Reliability
If multiple insulators are disposed at different portions of the vane, then insulation performance is improved, but device complexity increases
Solution Approach 1:
The insulator is segmented into a first insulator and a second insulator disposed at different portions of the vane (flat portion and inclined portion respectively). This segmentation improves insulation performance by covering different thermal zones while maintaining a relatively simple overall configuration that integrates with the vane structure
