Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operating frequency of the electronic element is increased, then the computing performance is improved, but the heat generated by the electronic element is increased
Solution Approach 1:
The fin elements extend in multiple directions (first direction and second direction) from the heat dissipation plate, creating a three-dimensional heat dissipation structure. This multi-directional extension increases the heat dissipation surface area in spatial dimensions, enabling more effective heat removal from the electronic element without limiting the operating frequency increase.
2Temperature
If a heat dissipation plate is used for heat dissipation, then the heat transfer from electronic element is improved, but the heat dissipation efficiency is insufficient when operating frequency increases
Solution Approach 1:
The heat dissipation plate is segmented into multiple fin elements that extend in different directions. This segmentation divides the heat dissipation function into multiple independent heat transfer paths, allowing heat to be dissipated simultaneously through multiple fins, thereby significantly improving overall heat dissipation efficiency compared to a single plate structure.
Solution Approach 2:
The fin elements extend in multiple directions (first direction and second direction) from the heat dissipation plate, creating a three-dimensional heat dissipation structure. This multi-directional extension increases the heat dissipation surface area in spatial dimensions, enabling more effective heat removal from the electronic element without limiting the operating frequency increase.
3Productivity
If multiple fin elements are added to improve heat dissipation, then the heat dissipation efficiency is improved, but the structural complexity increases
Solution Approach 1:
The heat dissipation plate and multiple fin elements are integrated and formed into one piece by die casting. This merging of components eliminates the need for separate assembly steps and fasteners, reducing structural complexity despite having multiple fin elements, while maintaining high heat dissipation efficiency through the multi-directional fin configuration.
