Battery Module Cooling Block Layout for Uniform Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module cooling systems suffer from inefficiencies, particularly in hybrid and electric vehicles, where the cooling efficiency of battery modules decreases as the cooling water flows through, leading to over-cooling of initial modules and decreased overall cooling efficiency.
Innovation Solution
A battery module cooling structure that includes a cooling block with a first and second cooling module, and valve members to control the flow of cooling water, allowing for selective cooling of battery modules to maintain optimal temperatures and improve cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling water flow rate is increased to cool later modules, then those modules achieve optimal temperature, but initial modules are over-cooled reducing overall efficiency
Solution Approach 1:
The flow resistance parameters of different cooling channels are adjusted to optimize cooling performance. By changing the flow rate parameters through different channel designs (channel width, length, bends), the system achieves optimal temperature control for each module group without over-cooling, maximizing overall cooling efficiency.
2Device complexity
If a single cooling block design is used for all battery modules, then the structure is simple, but cooling uniformity across modules deteriorates
Solution Approach 1:
The cooling block is segmented into multiple standardized cooling channel units that can be replicated and assembled. This modular segmentation maintains relative structural simplicity while enabling differentiated cooling paths for different module groups, achieving both simplicity and cooling uniformity.
