Engineering Contradiction Analysis
1Ease of manufacture
If a standard coolant manifold is used for multiple battery models, then manufacturing cost and component reusability are improved, but thermal management performance deteriorates due to inability to customize flow rates for different thermal requirements
Solution Approach 1:
The manifold is segmented into multiple outlets, each equipped with independently adjustable flow restrictors. This allows the coolant flow to be divided and customized for each cooling plate connection, enabling standard manifolds to adapt to different thermal management requirements of various battery models while maintaining cost-effectiveness.
Solution Approach 2:
The flow restrictors are designed to be adjustable, allowing the coolant flow rate to each outlet to be dynamically modified. This dynamic adjustment capability enables the same standard manifold to be customized for different battery thermal requirements without redesigning the entire manifold for each application.
2Temperature
If coolant flow rate is increased to reduce temperature spikes in high-temperature zones, then thermal management is improved, but energy consumption increases
Solution Approach 1:
Flow restrictors are selectively adjusted or configured at specific outlets based on the local thermal requirements of different battery zones. High-temperature zones receive higher coolant flow rates through appropriately sized restrictors, while cooler zones receive reduced flow, optimizing thermal management without unnecessarily increasing overall energy consumption.
Solution Approach 2:
The flow rate parameter is independently adjusted at each outlet through variable flow restrictors, allowing optimization of coolant distribution to match the spatial distribution of heat generation in the battery, thereby achieving better temperature uniformity with minimized energy consumption.
