Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-uniform heat absorption by fluid in heat pipes due to temperature differences caused by the flow rate and direction of exhaust gas in waste heat recovery boilers, leading to performance degradation.
Innovation Solution
The heat pipes are arranged in multiple rows along the direction of exhaust gas flow and connected using oblique and intersecting connection pipes, forming a zigzag or intersecting pattern, ensuring uniform heat exchange and absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat pipes are arranged in multiple rows along exhaust gas flow direction, then heat exchange efficiency is improved, but temperature distribution uniformity deteriorates due to upstream-downstream temperature differences
Solution Approach 1:
The heat pipe system is segmented into multiple independent rows, each row functioning as a separate heat exchange unit. This segmentation allows independent fluid circulation paths for each row, enabling uniform heat absorption across all rows despite the temperature gradient in exhaust gas flow direction.
Solution Approach 2:
The patent transitions from a single-row linear arrangement to a multi-row spatial configuration. By arranging heat pipes in multiple rows and connecting them through connection pipes, the system creates a three-dimensional heat exchange network that distributes heat more uniformly across the entire system, overcoming the one-dimensional temperature gradient problem.
2Device complexity
If connection pipes are arranged in parallel, then system complexity is reduced, but heat absorption uniformity deteriorates
Solution Approach 1:
The connection pipes are deliberately arranged in asymmetric, oblique configurations rather than simple parallel arrangements. This asymmetric design creates intersecting flow paths that distribute heat more evenly across different heat pipe rows, preventing the formation of hot spots and ensuring uniform heat absorption throughout the system.
