Advanced (Metal 3D-Printed) Direct Liquid Jet-Impingement Cooling Solution for Autonomous Driving High-Performance Vehicle Computer (HPVC)

In this paper, a High-Performance direct liquid jet-impingement cooler is presented to guarantee the proper thermal operating conditions in High-Performance processors (up to 300W), enabling level 5 autonomous driving. Computational Fluid-Dynamics (CFD) simulations are performed on the 3D model to reach the final design iteration and show the superior performances. The 3D metal printability of a prototyped liquid-based printed cooler version and the integration to a chip is demonstrated, furthermore experiments are carried out to proof the validity of the CFD modeling methodology and the enhanced potentialities of the solution compared to possible cooling alternatives.
