Efficient thermal management in EV battery packs requires balancing heat dissipation, temperature uniformity, pressure drop, and manufacturability. Coldstream©, Diabatix’ physics-based generative design platform, combines topology optimization with computational fluid dynamics to generate cooling channel geometries optimized for thermal and hydraulic performance. Benchmarked against conventional serpentine, pin-fin, and dimpled cold plates at thermal loads of 1.5 kW and 4 kW, the generated designs demonstrated improved thermal performance and temperature uniformity compared with dimpled configurations, while avoiding the high pressure drops associated with serpentine and pin-fin designs.
CNC milling constraints were incorporated directly into the optimization process, demonstrating how generative design can balance thermal performance, hydraulic efficiency, and manufacturability.
‍
- Optimize thermal and hydraulic performance simultaneously: Discover how generative design balances cooling efficiency, temperature uniformity, and pressure drop.
- Benchmark comparison with traditional designs: Learn how ColdStream achieves comparable cooling to serpentine channels with significant lower pressure drop, while improving thermal performance compared to dimpled or pin designs.
- Integrate manufacturability into optimization: Explore how CNC milling constraints are incorporated directly into the design process to generate geometries suited to the selected manufacturing method.
Future case studies in the cold plate series will focus on other manufacturing techniques such as stamping, multi-cell battery modules, and highly constrained design spaces
