Designing a Staggered Lithium Battery Pack with Hexagonal Fins The session focuses on designing a staggered lithium battery pack integrated with hexagonal fins and phase change material (PCM) for effective thermal management. The geometry is based on specific dimensions, including 2.5 mm fin thickness and 16 mm center-to-center cell distance, deviating slightly from the reference design by incorporating hexagonal structures instead of T-sections.
Creating Geometry in Fluid Flow Fluent Using Fluid Flow Fluent software, the initial step involves setting units to millimeters and creating box-shaped geometries followed by circular patterns representing cells. These circles are spaced at precise distances using angular measurements to ensure accuracy before extruding them into three-dimensional shapes.
Hexagon Fin Structure Development A new sketch introduces hexagons around each circle as part of the casing structure for enhanced heat dissipation efficiency. Dimensions like side length (2.5mm) are carefully defined while ensuring proper alignment through rotation techniques until all layers achieve uniformity across their respective positions within this arrangement.
'Meshing' Process Optimization & Boundary Naming Conventions. 'Mesh generation ensures computational precision during simulations; finer meshes improve results but demand higher memory resources.' Boundaries such as 'cell boundaries,' PCM regions or convection zones get named systematically aiding later analysis stages effectively reducing errors caused due misaligned definitions
