Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal transfer technologies face inefficiencies due to thermal and mechanical energy transfer from a thermal source or sink to a mass, leading to increased thermal load on the cold source and reduced heat removal efficiency.
Innovation Solution
The use of thermal transfer line assemblies comprising a vacuum housing, suspension support housing, and thermal conduit, with continuous voids and minimal mechanical contact, to minimize thermal and mechanical energy transfer, utilizing materials like copper and insulation to reduce heat and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a thermal transfer line assembly uses direct contact between the thermal conduit and housing structures, then mechanical support is simplified, but thermal energy transfer increases leading to higher thermal load on the cold source
Solution Approach 1:
The patent introduces suspension support housing and continuous voids as intermediary elements between the thermal conduit and outer housing. These intermediaries provide mechanical support while minimizing thermal contact, thereby reducing thermal load on the cold source without oversimplifying the support structure
Solution Approach 2:
The patent creates a vacuum environment within the housing to eliminate convective and conductive heat transfer through air. This inert environment (vacuum) allows the thermal conduit to be supported mechanically while preventing unwanted thermal energy transfer to the housing and surroundings
2Stability of the object's composition
If the thermal transfer line assembly uses extensive housing and support structures, then mechanical stability is improved, but thermal isolation is reduced leading to increased heat transfer
Solution Approach 1:
The patent uses thin-walled housing structures that provide mechanical stability while minimizing thermal mass and conductive heat transfer paths. The thin films and shells maintain structural integrity without creating excessive thermal bridges to the environment
Solution Approach 2:
The housing is divided into separate components (suspension support housing, outer housing, continuous voids) that are strategically positioned to provide mechanical stability at critical points while maintaining thermal isolation in other areas. This segmented approach allows optimized mechanical support without compromising thermal performance
