Additively Manufactured and Topology Optimized Heatsink for a Propulsion Motor

Abstract

Additive manufacturing, used in conjunction with topology optimization, allows the realization of complex algorithmically generated geometries with improved physical characteristics. In this paper, these methods are used to enhance the performance of an electrical propulsion drive via improved cooling capabilities. An air-cooled heatsink is modelled, optimized, and additively manufactured, after which practical measurements are performed. Finally, comparisons to a similarly sized conventional heatsink are used to demonstrate the benefits and potential limitations of topology optimization and additive manufacturing in the field of electrical machines.
