Insulating Panel Barrier Profile for Better Air Heat Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to optimize heat transfer to and from buildings due to increasing energy costs, which existing insulating technologies have not adequately addressed.
Innovation Solution
A composite insulating panel is developed, comprising a first sheet, a second sheet, and insulating foam with a longitudinally extending conduit means, where a barrier between the foam and the sheets is not planar, allowing for enhanced heat transfer by creating a larger void space for air circulation and heat exchange, and can be profiled or have crowns for increased efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a planar barrier is used between the foam and sheets, then the manufacturing is simpler, but the heat transfer efficiency is reduced due to limited void space for air circulation
Solution Approach 1:
The barrier is designed with a non-planar, curved profile that extends into the foam to create a void space. This curvature allows for increased air circulation volume while maintaining a continuous barrier function, thereby improving heat transfer efficiency without requiring complex multi-component structures.
Solution Approach 2:
The barrier transitions from a two-dimensional planar surface to a three-dimensional non-planar structure that protrudes into the foam. This dimensional change creates additional void space for air circulation while the barrier itself remains a single continuous element, resolving the contradiction between improved heat transfer and manufacturing simplicity.
2Loss of energy
If the conduit means is made larger to improve air circulation, then the heat transfer efficiency increases, but the insulating foam volume is reduced
Solution Approach 1:
The barrier is segmented into multiple longitudinal sections with varying profiles. Each section creates a localized void space optimized for air circulation, while the overall foam volume is preserved by confining the void spaces to specific regions rather than creating one large continuous void.
Solution Approach 2:
The barrier profile varies along its length, creating regions of different void space volumes. This local variation allows for optimized air circulation in specific areas where heat transfer is most needed, while maintaining adequate foam insulation in other regions.
3Loss of energy
If the barrier extends deeply into the foam to maximize void space, then the heat exchange capability improves, but the structural integrity of the foam is compromised
Solution Approach 1:
The barrier extends partially into the foam rather than fully penetrating it. This partial extension creates sufficient void space for effective heat exchange while leaving the majority of the foam structure intact to maintain structural integrity and support the barrier.
Solution Approach 2:
The foam structure is designed to accommodate the barrier extension with built-in structural redundancy. The surrounding foam acts as a cushioning support that maintains overall structural integrity even with the localized void spaces created by the barrier protrusion.

AI summary
An insulating panel 1 comprises a first sheet 2, a second sheet 4, and a body of insulating foam 5 between the sheets 2, 4. The foam 5 has a plurality of longitudinally extending conduits 7 through which a heat exchange medium such as air is circulated. A barrier 10 is used to create an enlarged void space for air circulation. The barrier is located below profile crowns 3 to prevent foam from entering the crowns 3 and to create additional foam-free voids below the crown. Heat transfer efficiency is increased.
