Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cooling water flows through heat-dissipating fins formed by punching a metal sheet, then the structure is simple and easy to manufacture, but the heat conduction effect is poor and cooling performance is reduced
Solution Approach 1:
The accommodating space is divided into multiple flow passages by partition plates, segmenting the cooling water flow path. This ensures that cooling water flows through all heat-dissipating fins sequentially, maximizing heat conduction across the entire fin array rather than allowing water to bypass certain areas.
Solution Approach 2:
Partition plates are introduced as intermediary components to guide and distribute cooling water uniformly across multiple flow passages. These plates ensure that cooling water makes full contact with all heat-dissipating fins, improving the intermediary heat transfer process between the fins and cooling water.
2Temperature
If the cooling water flow path is long to cover all heat-dissipating fins, then heat dissipation coverage is improved, but the cooling water temperature increases along the flow distance and heat conduction performance is reduced
Solution Approach 1:
The cooling water flow path is segmented into multiple parallel passages by partition plates. Each passage contains a subset of heat-dissipating fins, allowing cooling water to flow through all fins while maintaining shorter individual flow paths. This segmentation prevents excessive temperature rise in the cooling water while ensuring complete heat dissipation coverage.
3Device complexity
If the water inlet and outlet pipes are arranged in a traditional manner, then the structure is simple, but the impact cooling effect is insufficient and heat dissipation performance is reduced
Solution Approach 1:
The water outlet pipe is positioned at the front plate while the water inlet pipe is at the top plate, creating a three-dimensional angular arrangement (70-110 degrees) rather than a simple linear or parallel configuration. This spatial arrangement enables the cooling water to generate an impact cooling effect on the bottom plate, adding a dimensional aspect to the heat dissipation process that enhances thermal management.
