Metallized Textile Building Panel for Heat Transfer and Hidden Perforations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermally activated building panels face inefficiencies in thermal conduction and aesthetic issues due to the use of sound-absorbing microporous layers and perforated metal plates, which reduce thermal efficiency and make perforations visible, affecting both performance and appearance.
Innovation Solution
A thermally activated building panel with a metallized textile surface tensioned over a metal plate, where the first surface is coated with metal particles to enhance thermal conductivity and block light transmission, ensuring a smooth, even surface that hides the metal plate perforations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sound-absorbing microporous layer is applied to the metal plate, then sound absorption is improved, but thermal conduction between the layer and metal plate is reduced
Solution Approach 1:
The textile layer acts as an intermediary between the sound-absorbing microporous layer and the metal plate. It provides both acoustic damping properties and sufficient thermal conduction, mediating between the conflicting requirements of sound absorption and thermal efficiency.
Solution Approach 2:
The invention uses a composite structure combining textile material with specific thermal and acoustic properties. This composite approach allows simultaneous achievement of sound absorption and thermal conduction that neither material could provide alone.
2Object-affected harmful factors
If a sound-absorbing microporous layer is applied to the metal plate, then sound absorption is improved, but the circular perforations become visible through the layer
Solution Approach 1:
The textile layer serves as a visual intermediary that obscures the metal plate perforations from view while maintaining acoustic functionality. It mediates between the need for visible aesthetic appearance and the need for sound absorption.
3Illumination intensity
If a textile is arranged on the metal plate, then aesthetic appearance is improved, but thermal conduction between the textile and metal plate is reduced
Solution Approach 1:
The invention changes the thermal parameters of the textile material by selecting specific fiber types, densities, and thicknesses that maintain adequate thermal conduction while preserving aesthetic appearance. This allows optimization of thermal parameters without sacrificing visual quality.
4Ease of manufacture
If the textile is not tensioned, then installation is simpler, but the surface becomes uneven and perforations become visible
Solution Approach 1:
The textile is designed to be tensioned during installation to achieve the desired smooth surface, but the tensioning mechanism allows for adjustment and maintenance. This dynamic approach balances installation simplicity with aesthetic requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves thermal conduction between the textile and metal plate, maintains a smooth aesthetic, and effectively prevents the visibility of metal plate perforations, while maintaining or slightly reducing thermal performance compared to panels without a textile.

AI summary
The thermally activated building panel (1) includes a metal plate (2) having a room- facing surface (3) and a building-facing surface (4). A heat-exchanger tube (5) for conveying a cooling or heating medium is in conductive thermal contact with the building- facing surface (4) of the metal plate (2). A textile (9) is arranged on the room-facing surface (3) of the metal plate (2) and has a first surface (10) generally contacting the metal plate (2) and a second surface (11) generally visible from said room. The textile (9) is tensioned between opposed edges (12) of the metal plate (2). The first surface (10) of the textile (9) is metallized by deposition of metal particles on the textile (9).
