“…Recently, researchers have been inclined to improve cooling performance by modifying coolant properties, which refers to the method of adding nanoparticles (NPs) [73][74][75], surfactants [76,77], dissolving salts [78], water-soluble polymers [79,80], and other additives to the pure working fluid to change its surface tension and other characteristics. The most widely applied surfactants are cetyltrimethylammonium bromide (CTAB) as cationic, sodium dodecyl sulfate (SDS) as anionic, and polyoxyethylene (20) sorbitan monolaurate (Tween 20) as non-ionic additives.…”

As one of the most promising thermal management solutions, spray cooling has the advantages of high heat-transfer coefficient and maintaining a low temperature of the cooling surface. By summarizing the influential factors and practical applications of spray cooling, the current challenges and bottlenecks were indicated so as to prompt its potential applications in the future. Firstly, this paper reviewed the heat-transfer mechanism of spray cooling and found that spray cooling is more advantageous for heat dissipation in high-power electronic devices by comparing it with other cooling techniques. Secondly, the latest experimental studies on spray cooling were reviewed in detail, especially the effects of spray parameters, types of working fluid, surface modification, and environmental parameters on the performance of cooling system. Afterwards, the configuration and design of the spray cooling system, as well as its applications in the actual industry (data centers, hybrid electric vehicles, and so on) were enumerated and summarized. Finally, the scientific challenges and technical bottlenecks encountered in the theoretical research and industrial application of spray cooling technology were discussed, and the direction of future efforts were reasonably speculated.

“…The deposited nanoparticles decrease the surface roughness of the heated plate if the size of the deposited nanoparticles is smaller than that of the size of cavities of the heated surface. Bellerova et al [28,29] studied the spray cooling of 200 C temperature substrate by solid jets using watereAl 2 O 3 nanofluids and found that the nanofluids have poor heat transfer rate compared to that of water.…”

“…Bellerova et al 6 conducted an experimental and theoretical investigation into the spray cooling heat transfer performance of water/ alumina nanofluids, and found that the heat transfer coefficient reduced by around 45% as the nanoparticle volume fraction increased from 0 to 16.45 vol%. The same group 7 also measured the transient temperatures of a metal testing plate during spray cooling. The transient heat transfer coefficient was found to reduce by around 20% as the volume fraction of nanoparticles increased from 0 to 16.45 vol%.…”

This study investigated the spray cooling heat transfer performance of Al2O3-water nanofluid given four different subcooling degrees (0 °C, 10 °C, 20 °C, and 30 °C). The results showed that the subcooled nanofluids were ranked in order of a reducing spray cooling heat transfer performance as follows: 20 °C, 10 °C, 0 °C, and 30 °C. On average, the heat transfer coefficient obtained using the nanofluid with 20 °C subcooling was around 8.3%, 8.6%, and 15.6% higher than that obtained with 10 °C, 0 °C, and 30 °C subcooling, respectively. However, the heat transfer performance decreased with an increasing spray operating time. The scanning electron microscopy observations showed that the reduction in the heat transfer coefficient was the result of a gradual increase in the thickness of the nano-adsorption layer on the heated surface as the spray operating time increased.
