Research progress of spray cooling technology for avionics

With the rapid development of semiconductor technology, conventional cooling methods are difficult to meet the stricter heat dissipation requirements of electronic equipment. The spray cooling technology has become an effective method to solve the heat dissipation of highly integrated avionics due to its high heat transfer efficiency, uniform temperature at the heat exchange surface and less usage of working medium. We introduce the working principle of spray cooling in this paper. The influence factors of spray cooling technology are analyzed in terms of spray characteristics, coolant characteristics and surface characteristics We also summarize the research status of spray cooling technology in avionics. Finally, we point out the challenges for spray cooling technology under different gravities and accelerated vibration environment, and predict the future development trend of this technology for avionics.
