Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate cooling structures are added to cool battery packs, then heat dissipation capability is improved, but device complexity and space requirements increase
Solution Approach 1:
The cooling plate integrates both the cooling function and the support function into a single component. The battery packs are directly placed on the cooling plate, which serves as both the thermal management surface and the structural support base, eliminating the need for separate support structures and reducing overall system complexity.
Solution Approach 2:
The cooling plate performs multiple functions simultaneously: it provides thermal conduction for heat dissipation, structural support for the battery packs, and serves as a mounting surface for the cooling tubes. This multi-functionality reduces the number of components needed in the system.
2Ease of operation
If connection structures for cooling medium are added, then cooling system functionality is improved, but leakage risk increases
Solution Approach 1:
The connection structures for the cooling medium are embedded within the cooling plate itself. The cooling tubes pass through the cooling plate, and the connection points are integrated into the plate's structure, creating a nested arrangement where the connection structures are surrounded and protected by the cooling plate material.
Solution Approach 2:
The cooling plate, which is already present for thermal management purposes, is utilized to provide leakage protection for the cooling medium connection structures. The same component that conducts heat also serves as a barrier preventing cooling medium leakage, converting a potential harm (leakage risk at connection points) into a benefit (protected connection structures).

AI summary
A battery module includes a battery packs (M1, M2, M3). Heat may be efficiently dissipated from the battery packs (M1, M2, M3) of the battery module, and heat dissipating efficiency may not vary according to the positions of the battery packs (M1, M2, M3), that is, heat may be uniformly dissipated. In addition, leakage of a cooling medium for dissipating heat may be prevented, and permeation of the cooling medium into the battery packs (M1, M2, M3) may be prevented.
