Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional heat transfer devices are used, then the structure is simple and easy to manufacture, but the heat transfer efficiency is insufficient for high heat flux energy sources
Solution Approach 1:
The heat transfer plate is segmented into multiple fluidly isolated channels within a single body, allowing independent flow paths that increase heat transfer efficiency without requiring multiple separate components. This segmentation enables complex internal geometries while maintaining manufacturing feasibility through additive manufacturing processes.
Solution Approach 2:
The invention transitions from conventional two-dimensional heat transfer surfaces to three-dimensional square wave-shaped channels with multiple impingement zones. This dimensional change creates additional heat transfer surfaces and flow paths within the same footprint, significantly enhancing heat transfer efficiency for compact designs.
2Volume of moving object
If component sizes are shrunk to accommodate shrinking circuitry, then the device compactness is improved, but the heat transfer capability becomes increasingly difficult to maintain
Solution Approach 1:
Multiple fluidly isolated channels are nested within a single heat transfer plate body, allowing compact arrangement of multiple flow paths in a confined volume. This nesting approach maximizes heat transfer capability within the reduced size constraints of modern electronics.
Solution Approach 2:
The square wave-shaped channels utilize three-dimensional space more effectively by creating multiple impingement zones and extending flow paths vertically and laterally. This dimensional optimization allows enhanced heat transfer capability within a compact footprint suitable for shrinking circuitry.
3Reliability
If square wave-shaped channels with multiple impingement zones are implemented, then the heat transfer efficiency is enhanced, but the manufacturing complexity increases
Solution Approach 1:
Multiple fluidly isolated channels with complex square wave geometries are merged into a single unitary heat transfer plate body. This consolidation achieves enhanced heat transfer efficiency through complex internal structures while simplifying manufacturing by creating one integrated component rather than multiple assembled parts.
Solution Approach 2:
The invention changes the manufacturing approach from conventional machining to additive manufacturing, enabling the fabrication of complex square wave-shaped channels with multiple impingement zones. This parameter change in manufacturing technology allows realization of geometries that would be difficult or impossible to achieve with traditional methods.
4Area of stationary object
If multiple fluidly isolated channels are defined within the body, then the heat transfer surface area is increased, but the device complexity increases
Solution Approach 1:
Multiple channels requiring fluid isolation are merged into a single unitary heat transfer plate body defined by additive manufacturing. This approach increases the effective heat transfer surface area through multiple channels while avoiding the complexity of assembling multiple isolated components, as the isolation is achieved through the monolithic structure.
