Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If serial flow configuration is used for cooling modules, then device complexity is reduced, but cooling effectiveness deteriorates due to inconsistent temperature distribution
Solution Approach 1:
The cooling system is segmented into multiple independent cooling modules, each with its own containing chamber and cooling core pipe. This segmentation allows parallel flow configuration where cooling liquid can simultaneously cool multiple charging cables, ensuring consistent temperature distribution across all modules while maintaining manageable device complexity through modular architecture.
2Productivity
If high charging current is used to improve charging speed, then charging efficiency is improved, but temperature rise increases
Solution Approach 1:
The patent employs liquid cooling technology where cooling liquid flows through containing chambers and cooling core pipes to form a hydraulic cooling system. This hydraulic approach efficiently removes heat generated by high charging currents, enabling fast charging at 600A or 1000A while maintaining temperature within safe operating limits.
3Device complexity
If cooling liquid flows through charging cables in series, then device complexity is reduced, but cooling effectiveness of last cable deteriorates
Solution Approach 1:
The cooling system is segmented into multiple independent cooling modules, each with its own containing chamber and cooling core pipe. This segmentation allows parallel flow configuration where cooling liquid can simultaneously cool multiple charging cables, ensuring consistent temperature distribution across all modules while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent transitions from a one-dimensional serial flow arrangement to a multi-dimensional parallel flow architecture. By introducing multiple independent flow paths that operate simultaneously, the system achieves comprehensive cooling of all charging cables, with each cable receiving adequate cooling attention rather than the progressive cooling degradation seen in serial configurations.

The inlet pipe joint (22) is used to connect with a cooling liquid inlet pipe, and the multiple first mating pipe joints (21) are respectively connected to the first pipe joints (13) of the multiple cooling modules (1), so that the cooling liquid can flow into the containing chambers (101) of the multiple cooling modules (1) in parallel through the multi-channel pipe joint component (2). The second pipe joints (11a) of the multiple cooling modules (1) are used to connect with cooling core pipes (31) of multiple charging cables (3) respectively, so that the cooling liquid in the multiple cooling modules (1) can flow through the cooling core pipes (31) of the multiple charging cables (3) in parallel. The present invention can ensure that multiple charging terminals are sufficiently cooled and the temperature remains consistent, and can also ensure that multiple charging cables are sufficiently cooled and the temperature remains consistent.
