Engineering question

The package space was to be reduced without compromising air cooling through excessive pressure loss.

Model & approach

Vary the gap between battery modules parametrically
Compare pressure loss and flow distribution
Include temperature distribution as a cooling criterion

Boundary conditions

Multiple wall or module gaps
Same container and cooling concept as the comparison basis
Evaluation of pressure and temperature fields

Results of the assessment

The predicted pressure loss increased as the gap narrowed.
The published study describes cooling performance as remaining satisfactory.
The assessment established sufficient module spacing as a design constraint.

Engineering consequence

The recommended minimum balanced packaging and airflow margin for the modeled layout.

Context

The spacing recommendation applies to the geometry and flow condition assessed.
