Submitted: 14 January 2026 You are already at the latest version The study presents a novel process to design lightweight, high-performance cooling manifolds for power electronics using generative design (GD). The process begins with a baseline design that defines the constraints of the manifold with regard to the target cooling geometry and flow path. A GD flow optimization is then performed to minimize pressure drop and improve flow uniformity.
