Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional coolant distribution methods are used, then the apparatus structure is simple, but the temperature distribution across the battery module is uneven
Solution Approach 1:
The coolant distribution apparatus is segmented into multiple plenums (first plenum, second plenum, third plenum) and multiple channels arranged in parallel or hybrid configurations. This segmentation allows independent coolant flow paths that can be optimized to deliver uniform coolant distribution across different regions of the battery module, thereby achieving uniform temperature distribution while managing structural complexity through modular design
Solution Approach 2:
Different regions of the battery module are served by channels with locally optimized characteristics. The parallel and hybrid channel configurations allow each channel to be tailored for its specific region's thermal requirements, ensuring that each local area receives appropriate coolant flow to maintain uniform temperature across the entire battery module
2Stress or pressure
If coolant flow paths are simplified, then the apparatus is easier to manufacture, but coolant pressure consistency deteriorates
Solution Approach 1:
The coolant distribution system is divided into multiple segmented plenums and channels that can be manufactured as separate components and then assembled. This segmentation maintains pressure consistency by creating balanced flow paths while simplifying manufacturing, as each segment can be produced using standard fabrication processes and then joined together to form the complete distribution apparatus
Solution Approach 2:
Multiple parallel channels and plenums are merged into a single integrated coolant distribution apparatus. This merging maintains consistent coolant pressure across all channels by providing multiple redundant flow paths, while the overall structure remains manufacturable through standardized component design and assembly procedures
