Heat conduction sheet and method of manufacturing such a sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchangers with perforated heat-conducting plates face a trade-off between improved acoustic properties and maintained heat conduction, as uniform perforations across the plate compromise thermal efficiency.
Innovation Solution
The perforations are concentrated in the peripheral regions of the heat-conducting plate, with fewer or no perforations in areas where the plate contacts the pipe section, and more perforations in lateral regions to enhance heat conduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the heat-conducting plate is perforated to improve acoustic properties, then acoustic absorption is improved, but heat conduction performance deteriorates
Solution Approach 1:
The heat-conducting plate is designed with non-uniform perforation distribution, where peripheral regions have more or larger perforations for acoustic absorption, while the central region has fewer or no perforations to maintain heat conduction performance. This local differentiation allows each region to optimize its specific function.
Solution Approach 2:
The plate is functionally segmented into different zones: a central region optimized for heat conduction with minimal perforations, and peripheral regions optimized for acoustic absorption with increased perforations. This segmentation resolves the contradiction by allowing both functions to coexist in different spatial locations.
2Object-affected harmful factors
If perforations are evenly distributed over the entire surface, then acoustic properties are optimized, but heat conduction in contact areas deteriorates
Solution Approach 1:
The perforation density is locally adapted to functional requirements: low density in the central heat conduction zone and high density in peripheral acoustic zones. This local quality differentiation ensures optimal temperature transfer in contact areas while maintaining acoustic properties elsewhere.
Solution Approach 2:
The perforation distribution follows an asymmetric pattern rather than uniform distribution, with the central region having different perforation characteristics compared to peripheral regions. This asymmetric design allows the plate to simultaneously satisfy conflicting requirements of heat conduction and acoustic absorption.
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
This non-uniform perforation arrangement maintains acoustic properties while improving heat conduction by optimizing temperature transfer between the heat-conducting plate and pipe section.
Implementation Method 1
the acoustic properties of a corresponding heat exchanger can thus indeed be improved... sound waves entering the holding cassette are not necessarily reflected back in the region of the heat-conducting plate, but are at least partially absorbed
Implementation Method 2
the heat conduction properties of the entire heat exchanger... the temperature difference transferred in the contact area between the heat-conducting plate and the pipe section can be passed on better (to the holding surface)
