- Model passive and forced airflow including opening-layout variants
Project study
Passive and active air cooling of a battery module
The study scope covers passive heat rejection and forced-air cooling of a battery module under transient operating profiles and alternative inlet and outlet arrangements.
CFD simulation · Thermal analysisBattery-module air cooling
Engineering question
Heat generation, operating profile and a compact enclosure had to be translated into a cooling concept that made critical regions and the required air path assessable.
Boundary conditions
- Internal conduction and heat rejection from the module
- Project-specific operating profiles, openings and active airflow
Assessment focus
- Transient temperature development with passive and forced-air cooling
- Effect of enclosure openings and airflow paths on heat rejection
Study objective
The model was intended to support selection between passive and active cooling and development of the opening layout.
