Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the thickness of the heat radiation device is increased to improve heat diffusion efficiency, then heat diffusion efficiency is improved, but the overall thickness of the device increases
Solution Approach 1:
The heat radiation device is segmented into multiple flow paths (first flow path and second flow path) that are recessed into the core plate from opposite surfaces. This segmentation allows heat to be diffused through multiple parallel channels within the same thickness, effectively increasing heat diffusion efficiency without increasing the overall device thickness.
Solution Approach 2:
Instead of increasing thickness in the vertical dimension to improve heat diffusion, the invention creates additional flow paths by recessing into the core plate from both upper and lower surfaces. This utilizes the horizontal plane and bidirectional access to create multiple heat diffusion channels within the constrained thickness, effectively adding dimensional complexity without increasing overall size.
2Productivity
If multiple flow paths are added to increase heat diffusion efficiency, then heat diffusion efficiency is improved, but device complexity increases
Solution Approach 1:
The core plate serves multiple functions: it acts as the structural body of the heat radiation device, provides the housing for both the first and second flow paths, and serves as the heat diffusion medium itself. By making the core plate multi-functional, the invention achieves complex heat diffusion patterns without proportionally increasing overall device complexity.
Solution Approach 2:
The first flow path and second flow path are merged within a single core plate structure, with both paths sharing the same structural medium. This merging approach allows multiple heat diffusion channels to coexist within one unified component, achieving enhanced heat diffusion efficiency while avoiding the complexity of assembling multiple separate components.

AI summary
A heat radiation device includes a core plate, a first flow path in which one surface of the core plate is recessed in the thickness direction of the core plate to form a path in which refrigerant flows through, a second flow path in which the other surface opposite to the one surface of the core plate is recessed in the thickness direction of the core plate to form a path in which the refrigerant flows through, and a connection portion connecting the first flow path and the second flow path.
