3D-Printed Direct Liquid Multi-Jet Impingement Cooling Solutions for Power Electronics in Electrified Automotive Transportation

A metal 3D-printed high performance multi-jet impingement cooling solution for enabling thermal management of power electronics is presented for integration in electric vehicles. In this paper, we describe the concept, metal additive manufacturing and assembling to demonstrate the proof-of-concept of direct liquid jet impingement cooling of mock-up power modules dissipating heat loss up to 400 W (~230 W/cm²).
