Engineering Contradiction Analysis
1Area of stationary object
If a single large cooling plate is produced for large battery modules, then cooling coverage is improved, but manufacturing complexity increases and production becomes difficult
Solution Approach 1:
The cooling device is divided into a first cooling member and a second cooling member, each with independent flow channels. These separate cooling members can be manufactured independently using standard aluminum extrusion molding processes, avoiding the complexity of producing a single large cooling plate while maintaining comprehensive cooling coverage through their combined arrangement.
2Reliability
If cooling plate undergoes multiple sequential processes (stamping, graphite screen printing, gas blowing, cutting, punching), then cooling performance is improved, but production time and complexity increase
Solution Approach 1:
The flow channels are formed directly during the aluminum extrusion molding process itself, rather than requiring subsequent stamping, graphite screen printing, gas blowing, cutting, and punching operations. This preliminary formation of flow channels during the primary manufacturing process significantly reduces production time and complexity while maintaining effective cooling performance.
3Strength
If cooling plate is produced by traditional stamping and sequential processes, then structural integrity is maintained, but adaptability to different battery module sizes is reduced
Solution Approach 1:
The divided cooling member structure allows flexible configuration and arrangement to match different battery module sizes and shapes. Each cooling member can be independently designed and manufactured to fit specific applications, enhancing adaptability while maintaining structural integrity through standard aluminum extrusion processes.
