Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the interval between tubes is widened to facilitate insertion of electrical device, then ease of operation is improved, but heat exchange efficiency deteriorates due to reduced pressing force
Solution Approach 1:
A pressing member is introduced as an intermediary component between the tube and the electrical device. This pressing member transmits pressing force from the tube to the electrical device, ensuring adequate contact pressure for heat exchange while allowing the tube interval to be widened for easier insertion of the electrical device.
2Manufacturing precision
If heat exchanger is brazed to fix insertion space, then manufacturing precision is improved, but ease of operation deteriorates due to difficulty in insertion
Solution Approach 1:
The heat exchanger is divided into separate modular components: the tube assembly and the electrical device assembly. This segmentation allows the electrical device to be inserted into the heat exchanger before final assembly, facilitating easier insertion operations while maintaining precise positioning through the modular structure.
Solution Approach 2:
The electrical device is inserted into the heat exchanger structure before the pressing member is installed and activated. This preliminary insertion action allows the device to be positioned in place while the pressing force is applied subsequently, making the insertion process easier while ensuring proper contact.
3Device complexity
If single side cooling is used, then device complexity is reduced, but cooling performance deteriorates
Solution Approach 1:
The cooling structure transitions from single-side cooling to dual-side cooling by adding cooling tubes on both sides of the electrical device. This dimensional expansion from one side to two sides significantly improves cooling performance by increasing the heat exchange surface area, while the modular tube design keeps the overall structural complexity manageable.
