Engineering Contradiction Analysis
1Temperature
If conventional current busbar is used to connect electronic devices, then electrical connection is established, but high operating temperatures cause failure due to inadequate heat management
Solution Approach 1:
The busbar is divided into multiple segments with alternating polarities (first busbar segment with first polarity, second busbar segment with second polarity, third busbar segment with first polarity). This segmentation allows integration of cooling channels between segments while maintaining electrical connectivity, effectively managing heat generation and distribution across the busbar structure.
Solution Approach 2:
An insulation member with cooling channel is introduced as an intermediary component between the busbar segments. This intermediary serves dual functions: providing electrical insulation between segments of opposite polarity and facilitating heat dissipation through integrated cooling channels that receive coolant from the fluid dispenser.
2Temperature
If cooling fluid channels are integrated into the busbar structure, then heat dissipation is improved, but device complexity increases
Solution Approach 1:
The insulation member and cooling channel are merged into a single integrated component. The cooling channel is formed within the insulation member itself, combining the functions of electrical insulation and thermal management in one element, thereby reducing overall device complexity while achieving effective heat dissipation.
Solution Approach 2:
The insulation member serves multiple functions simultaneously: providing electrical insulation between busbar segments of opposite polarity, structurally supporting the busbar assembly, and facilitating heat dissipation through its integrated cooling channel. This multi-functionality reduces the need for separate components.
