Abstract

A method of cooling a battery cell includes: atomizing a cooling fluid by driving it through a micro-nozzle at a pressure sufficient to create a jet of aerosolized liquid droplets while retaining sufficient momentum in flow of the fluid to travel from the nozzle to an outer surface of the battery cell; impinging the spray of the jet of aerosolized liquid droplets on an outer surface of the battery cell; partially evaporating the liquid droplets on the outer surface to conduct heat from the outer surface; and convecting heat from the outer surface of the battery via the cooling fluid.
