Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If liquid cooling flow channels are used to enhance heat dissipation efficiency, then heat dissipation performance is improved, but temperature uniformity across the width direction deteriorates due to significant variations in cooling effectiveness
Solution Approach 1:
The patent introduces flow guide structures (flow guide pillars and flow guide plates) at specific locations where flow velocity varies significantly. These local modifications redirect the cooling medium flow to ensure uniform velocity distribution across the width direction, thereby achieving uniform temperature distribution without compromising overall heat dissipation efficiency.
2Temperature
If flow guide structures are added to improve flow velocity uniformity, then temperature consistency is improved, but device complexity increases
Solution Approach 1:
The flow guide structure is segmented into multiple independent components: flow guide pillars positioned at junctions and flow guide plates arranged along the flow channels. This segmentation allows for modular manufacturing and assembly, reducing the complexity of fabricating a fully integrated flow guide system while still achieving uniform flow velocity distribution.
3Speed
If the flow guide pillar is positioned close to the separating strip to maximize flow guidance, then flow velocity uniformity is improved, but structural strength and anti-noise capability deteriorate
Solution Approach 1:
The flow guide pillar is preliminarily positioned at a optimized distance from the separating strip that balances flow guidance effectiveness with structural strength requirements. This preliminary positioning, combined with the support from the flow guide plate, ensures that the flow velocity is sufficiently uniform while maintaining adequate structural integrity and noise resistance.
