Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat transfer pipes in heat exchangers face inefficiencies in heat exchange due to limited contact area and time between the fluid and the pipe, and accumulated alien substances impede fluid flow and reduce heat exchange efficiency, shortening the life of the exchanger.
Innovation Solution
A turbulence generating device is inserted into the fluid transfer pipe, featuring a body with discontinuities and impellers that create turbulence and vortices, increasing the fluid's contact area and time with the pipe, and an annular bead or flange for enhanced fluid mixing, which helps in removing accumulated substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional heat transfer pipes are used with straight or coil shapes, then the structure is simple and easy to manufacture, but the contact area and contact time between fluid and pipe are limited, reducing heat exchange efficiency
Solution Approach 1:
The pipe is divided into multiple sections with different cross-sectional areas along its length. These segments create alternating expansion and contraction zones that generate turbulence and increase fluid-pipe contact time, thereby improving heat exchange efficiency without requiring complex external structures
Solution Approach 2:
The invention introduces longitudinal variation in cross-sectional area along the pipe axis, adding a dimensional feature that transforms the previously uniform or simple coil structure into a multi-dimensional geometry that enhances fluid mixing and contact area while maintaining structural simplicity
2Reliability
If conventional heat transfer pipes are used, then the structure is simple, but alien substances accumulate inside the pipe, impeding fluid flow and reducing heat exchange efficiency
Solution Approach 1:
The segmented structure with varying cross-sectional areas creates multiple flow direction changes and turbulence zones that prevent alien substances from settling and accumulating in any single location, thereby maintaining pipe reliability and extending heat exchanger life
Solution Approach 2:
The pipe structure creates dynamic flow conditions through its varying cross-section, generating turbulence and flow reversal that actively prevents static accumulation of alien substances, transforming the static accumulation problem into a dynamic clearing mechanism
