NREL Tests New Structure for Jet Impingement Cooling of Power Electronics

NREL's Transportation Technologies and Systems researchers tested a novel prototype heat exchanger that uses jet impingement cooling and does not restrict heat flow in the power electronic components of advanced vehicles. Power electronics modules and electric motors are critical systems for advanced plug-in hybrid electric and electric vehicles. Power electronics can generate excessive heat, which degrades their performance, reliability, and life. NREL focuses on developing thermal management technologies that help to increase power density and lower system costs.
