Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one radiator is shared by battery module and electronic component core, then device complexity is reduced, but thermal efficiency deteriorates due to different temperature ranges
Solution Approach 1:
The patent divides the cooling system into separate radiators: one dedicated radiator for the battery module and another for the electronic component core. This segmentation allows each radiator to be optimized for its specific temperature range, with the battery radiator operating at lower temperatures and the electronic component radiator at higher temperatures, thereby resolving the thermal efficiency loss caused by shared radiator operation.
2Volume of moving object
If conventional battery temperature control system is installed adjacent to air-conditioning devices, then space utilization is improved, but thermal efficiency deteriorates
Solution Approach 1:
The patent extracts the battery cooling function from the air-conditioning system by providing a dedicated battery cooling apparatus with its own radiator and circulation system. This separation removes the thermal interference between battery cooling and passenger compartment air-conditioning, allowing both systems to operate independently at their optimal temperatures without compromising thermal efficiency.
3Productivity
If direct contact cooling with battery module is used, then cooling efficiency is improved, but safety deteriorates due to fire risk from cooling water leakage
Solution Approach 1:
The patent introduces an intermediary heat exchange mechanism where the battery module is cooled indirectly through a heat exchanger rather than direct contact with cooling water. The cooling water circulates in a closed loop through the heat exchanger, absorbing heat from the battery module without directly contacting it, thereby maintaining high cooling efficiency while eliminating fire safety risks from potential leakage.
4Productivity
If cooling system is designed for high-voltage battery module, then battery performance is improved, but weight increases
Solution Approach 1:
The patent optimizes the cooling system parameters including using a dedicated radiator sized appropriately for the battery module's thermal load, selecting cooling fluid flow rates and temperatures matched to high-voltage battery requirements, and designing the circulation pump with variable speed control. These parameter optimizations ensure adequate cooling performance for high-voltage batteries while minimizing the weight of cooling system components.
