Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the flow channel length is increased to extend cooling liquid residence time, then the heat dissipation efficiency is improved, but the hardware dimensions are exceeded and the device complexity increases
Solution Approach 1:
The patent introduces vortex generating structures with curved surfaces that induce rotational flow of the cooling liquid. The curved geometry transforms linear flow into rotational flow patterns, increasing residence time without extending the linear dimensions of the heat exchanger module.
Solution Approach 2:
The invention adds a rotational dimension to the cooling liquid flow by generating vortices. This transforms the flow from a simple linear path to a three-dimensional rotational pattern, effectively increasing the time the cooling liquid spends in contact with heat-generating surfaces without increasing the physical length of the device.
2Loss of time
If the flow channel length is increased to extend cooling liquid residence time, then the heat dissipation efficiency is improved, but the device complexity increases
Solution Approach 1:
The vortex generating structures utilize simple curved surfaces to induce rotational flow. These curved elements are geometrically simple yet effectively transform the flow pattern, avoiding the need for complicated curved flow channels while achieving extended residence time.
3Productivity
If conventional cooling structures are used, then the manufacturing is simple, but the heat dissipation efficiency is insufficient for high-performance electronic components
Solution Approach 1:
The vortex generating structures are formed using standard curved surface geometries that can be manufactured using conventional machining or molding techniques. The curved surfaces are integrated into the existing heat exchanger structure, maintaining manufacturing simplicity while significantly improving heat dissipation efficiency through enhanced cooling liquid circulation.
