Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for heads used in curing inner pipeline resin linings suffer from inefficient heat dissipation due to heterogeneous air flow and turbulence in complex housing designs, which reduces the effectiveness of cooling and shortens the lifespan of LEDs and other heated components.
Innovation Solution
A housing design featuring a unique, elongated cooling passage system with a constant cross-sectional area, where the passages are significantly longer than the housing itself, ensuring laminar air flow and even distribution around the X-axis, with outlets on the side surface and potential use of metal 3D printing for enhanced cooling capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If complex housing designs with multiple cooling passages are used, then heat dissipation area is increased, but air flow heterogeneity and turbulence increase reducing cooling effectiveness
Solution Approach 1:
The housing is divided into multiple cooling passages (first cooling passage, second cooling passage, third cooling passage) that are distributed around the X-axis. Each passage functions as an independent cooling channel, allowing the system to achieve comprehensive heat dissipation while maintaining simple laminar flow in each individual passage, thus resolving the contradiction between heat dissipation area and flow homogeneity.
Solution Approach 2:
The cooling passages are positioned asymmetrically around the X-axis at specific angular intervals (e.g., 120 degrees apart for three passages). This asymmetric distribution optimizes the heat dissipation coverage while maintaining symmetric thermal performance, allowing effective cooling without creating flow turbulence that would result from irregular positioning.
2Temperature
If longer cooling passages are used, then cooling capacity is increased, but housing volume increases
Solution Approach 1:
The cooling passages extend in the longitudinal direction of the housing rather than radially outward. By utilizing the length dimension of the housing, the design achieves long cooling passages (e.g., 6 times the housing length) without increasing the radial or transverse dimensions, thus maintaining compact external dimensions while maximizing cooling capacity through extended passage length.
Solution Approach 2:
Multiple cooling passages are nested within the housing structure, with passages positioned concentrically or in close proximity to each other. This nesting arrangement allows long passages to be accommodated within the housing volume by efficiently utilizing the internal space, avoiding the need for large housing dimensions.
