Metal-based Direct Multi-jet Impingement Cooling Solution for Autonomous Driving High-Performance Vehicle Computer ( HPVC)

Abstract

A metal 3D-printed high performance multi-jet impingement cooling solution for enabling thermal management of high- power electronics is presented for level-5 autonomous driving. In this paper, we describe the concept, metal 3D printing fabrication and experimental characterization to demonstrate the proofof-concept of direct liquid cooling of high-power components dissipating up to 300 W.
