Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plate-type heat exchangers suffer from low heat exchange efficiency due to laminar internal flow and localized high temperatures leading to scale formation, which affects durability and hygiene.
Innovation Solution
A heat exchanger design with specific reference areas on plates where heat emitting parts are strategically positioned to avoid high temperature zones, combined with rib structures for turbulence and a descaling mechanism to manage scale formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ribs are disposed in the inner passage to generate vortexes and increase heat transfer efficiency, then heat transfer efficiency is improved, but local temperature imbalance occurs leading to scale formation
Solution Approach 1:
The patent applies local quality by selectively positioning heat emitting parts only in specific areas (first and second areas) of the plate, excluding the third area where ribs are located. This creates non-uniform heat distribution that prevents local temperature imbalance and scale formation while maintaining overall heat transfer efficiency through the rib-generated vortexes in other regions.
Solution Approach 2:
The plate's heat emitting area is segmented into multiple regions (first area, second area, and third area), with heat emitting parts selectively placed in certain segments. This segmentation allows different regions to serve different functions: the first and second areas provide heat emission while the third area with ribs handles turbulence generation without direct heat emission, preventing scale formation.
2Power
If heat emitting part is coupled to entire area to maximize heat output, then heat output is improved, but local high temperature areas cause accelerated scale generation
Solution Approach 1:
Instead of uniformly distributing heat emitting parts across the entire plate area, the patent applies local quality by concentrating heat emitting parts only in specific regions (first and second areas) while excluding the third area adjacent to ribs. This creates a non-uniform heat distribution pattern that maintains high overall heat output while preventing localized overheating that would accelerate scale formation.
Solution Approach 2:
The patent converts the potential harm of ribs causing local temperature imbalance into a benefit by strategically excluding heat emitting parts from the third area adjacent to ribs. This design choice uses the rib structure's turbulence-generating capability while avoiding its harmful thermal effects, effectively turning a problematic feature into an opportunity for optimized heat distribution.
