Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the heat exchanger is manufactured to have a narrow width to reduce vehicle space occupation, then the vehicle space efficiency is improved, but the cooling performance and drainage performance deteriorate
Solution Approach 1:
The header tank is divided into multiple spaces by a separation wall that partitions the flow path in the width direction. This segmentation allows the heat exchanger to maintain effective flow paths and heat exchange surfaces even when the overall width is reduced, thereby preserving cooling and drainage performance in a compact form factor.
Solution Approach 2:
The separation wall is configured to extend in the longitudinal direction rather than only the width direction, creating drainage spaces that utilize the length dimension. This dimensional reorganization allows condensate water to be discharged effectively without increasing the heat exchanger width, thus maintaining compactness while ensuring drainage performance.
2Reliability
If the header tank is divided by a separation wall to improve drainage performance, then the drainage efficiency is improved, but the device complexity increases
Solution Approach 1:
The separation wall serves dual functions: it divides the flow path in the width direction to create separate drainage spaces, and simultaneously provides a surface for condensate water to accumulate and discharge in the longitudinal direction. By combining these functions into a single structural element, the design achieves improved drainage performance without proportionally increasing complexity.
Solution Approach 2:
The separation wall acts as a multi-functional component that performs flow path division, condensate collection, and drainage discharge. This universal structure eliminates the need for separate drainage components, thereby improving drainage performance while minimizing the increase in overall device complexity.
3Productivity
If the heat exchanger core part is configured with multiple tubes and fins to improve heat exchange performance, then the cooling efficiency is improved, but the manufacturing cost increases
Solution Approach 1:
The core part is divided into multiple independent tube assemblies arranged in parallel. Each tube with fins can be manufactured separately using standard extrusion and finning processes, then assembled into the header tank. This segmentation allows for optimized mass production of individual components while maintaining high overall heat exchange performance through the combined effect of multiple tubes.
