Abstract

Thermal management plays a crucial role in the development of efficient electric vehicles. Namely, in the case of energy demands during power peaks, major losses occur in power electronic devices during the vehicle's driving cycle. The flexibility required to efficiently dissipate the energy released in power electronic devices suggests the development of innovative intelligent thermal management systems, able to respond to these power peaks. In this paper, the spray cooling technology is explored toward an intelligent thermal management, using intermittent sprays produced by multijet impingement atomization. The heat losses consider the typical values found in IGBT semiconductor devices, such as converters, or inverters. The analysis is based on the correlation between the spray characteristics and the surface thermal behaviour, from the point of view of an active control of the cooling process, as well as the quantification of the benefit from phase-change.
