Engineering question
Electrical heat sources, solid conduction and coolant flow had to be brought together within one transient model boundary.
Boundary conditions
- Time-dependent electrical profile and defined initial state
- Project-specific coolant, material and contact assumptions
Assessment focus
- Temperature histories in cells and current-carrying interconnects throughout the load profile
- Effect of cooling channels, material properties and thermal contacts on heat rejection
Study objective
The objective was to assess critical temperature locations and cooling-channel design under transient electrical loading.
