VSEngineering Contradiction Analysis

1Device complexity

If cooling fluid flows along the longitudinal axis to absorb heat from each electronic module in series, then the cooling system can be simple in structure, but the temperature uniformity across modules deteriorates and pumping energy requirements increase

Solution Approach 1:

The cooling system is segmented into multiple transverse cooling channels, each independently serving an electronic module. This segmentation allows parallel cooling operation, improving temperature uniformity while maintaining structural simplicity through modular channel design

Inventive Principle:

Solution Approach 2:

The cooling fluid flow direction is changed from longitudinal (parallel to the axis) to transverse (perpendicular to the axis). This dimensional change enables parallel heat transfer paths, achieving uniform temperature distribution across all modules without increasing system complexity
