Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery modules are arranged in fixed positions with direct pipeline connections, then the cooling system structure is simple, but the temperature distribution among battery modules becomes inconsistent due to boundary convection and module arrangement
Solution Approach 1:
The flow distribution component is designed to be rotatable relative to the mounting component, transforming the static cooling system into a dynamic one. This allows the flow direction to be adjusted according to different battery module temperature distributions, enabling adaptive cooling that maintains temperature uniformity without requiring a complex reconfigurable pipeline system
Solution Approach 2:
The rotatable flow distribution component enables localized adjustment of coolant flow direction to specific battery modules that require cooling. By directing flow to high-temperature areas while reducing flow to cooler areas, the system achieves uniform temperature distribution across all modules without requiring different pipeline configurations for each module
2Temperature
If the flow field is adjusted by redesigning the entire rack, then the temperature uniformity can be improved, but the development cost and cycle increase significantly
Solution Approach 1:
The cooling system is segmented into independent components: the mounting component fixed in the rack and the rotatable flow distribution component that can be adjusted separately. This segmentation allows flow field optimization without redesigning the entire rack structure, significantly reducing development time and cost while maintaining temperature uniformity
Solution Approach 2:
The rotatable flow distribution component provides dynamic adjustability, allowing the flow field to be optimized for different battery configurations and thermal conditions without requiring physical redesign of the cooling system. This dynamic capability eliminates lengthy development cycles associated with static redesign approaches
3Temperature
If the flow distribution component can rotate to adjust flow direction, then the temperature uniformity improves, but the device complexity increases
Solution Approach 1:
The rotatable flow distribution component introduces minimal dynamic complexity (rotation capability) that directly addresses the temperature uniformity problem. This simple rotational mechanism provides significant functional improvement without requiring complex multi-component systems, achieving an optimal balance between complexity and performance

Function Achieved in This Case
The design enhances temperature uniformity during charging and discharging by flexibly adjusting coolant flow, reducing costs and shortening development cycles by allowing for customizable flow distribution without redesigning the entire rack.
Implementation Method 1
The flow distribution component is connected to the mounting component, and is capable of rotating relative to the mounting component to change a flow direction of the medium distributed through the flow guide hole
Implementation Method 2
During the immersion fluid circulation process between the a plurality of immersion battery compartments and the fluid channels, the temperature of the battery modules placed in the plurality of immersion battery compartments may be inconsistent due to the arrangement of the battery modules, boundary convection, and other factors
