“…The advantages of the practical application of the surface treated with plasma [81,103,104,107], in comparison with surface modification by other methods (see reviews [88][89][90][91][92][93][94][108][109][110]), are high rates of intensification of heat transfer and CHF achieved (up to four times) in comparison with the unmodified surface. Surface treatment by high-temperature plasma makes it possible to form a surface structure that is resistant to degradation, especially using refractory metals in special heat exchange devices.…”

The review summarizes recent experimental results of studying heat transfer on rough surfaces synthesized by plasma. The plasma-surface interaction leads to the stochastic clustering of the surface roughness with a high specific area breaking the symmetry of the virgin surface of the initial crystalline materials. Such a surface is qualitatively different from the ordinary Brownian surface. The micro- and nanostructured surface consist of pores, craters, and nanofibers of size from tens of nanometers to tens of microns, which can provide new heat transfer properties related to a violation of the symmetry of the initial materials. In recent years, new results have been obtained in the study of heat transfer during phase change on plasma-modified surfaces in relation to energy, chemical, and cryogenic technologies. The objective of the review is to describe the specific structure of refractory metals after high-temperature plasma irradiation and the potential application of plasma processing of materials in order to create heat exchange surfaces that provide a significant intensification of two-phase heat transfer. Refractory metals with such a highly porous rough surface can be used as plasma-facing components for operation under extreme heat and plasma loads in thermonuclear and nuclear reactors, as catalysts for hydrogen production, as well as in biotechnology and biomedical applications.

“…Jet impingement cooling has been widely adopted for thermal management in various industrial applications because of its prominent capability of dissipating large heat flux. However, it has not been implemented in marketed vehicles and aircraft [91][92][93]. Figure 10a shows a schematic of a jet impingement cooling power inverter module.…”

In recent years, global automotive industries are going through a significant revolution from traditional internal combustion engine vehicles (ICEVs) to electric vehicles (EVs) for CO2 emission reduction. Very similarly, the aviation industry is developing towards more electric aircraft (MEA) in response to the reduction in global CO2 emission. To promote this technology revolution and performance advancement, plenty of electronic devices with high heat flux are implemented on board automobiles and aircraft. To cope with the thermal challenges of electronics, in addition to developing wide bandgap (WBG) semiconductors with satisfactory electric and thermal performance, providing proper thermal management solutions may be a much more cost-effective way at present. This paper provides an overview of the thermal management technologies for electronics used in automobiles and aircraft. Meanwhile, the active methods include forced air cooling, indirect contact cold plate cooling, direct contact baseplate cooling, jet impingement, spray cooling, and so on. The passive methods include the use of various heat pipes and PCMs. The features, thermal performance, and development tendency of these active and passive thermal management technologies are reviewed in detail. Moreover, the environmental influences introduced by vibrations, shock, acceleration, and so on, on the thermal performance and reliability of the TMS are specially emphasized and discussed in detail, which are usually neglected in normal operating conditions. Eventually, the possible future directions are discussed, aiming to serve as a reference guide for engineers and promote the advancement of the next-generation electronics TMS in automobile and aircraft applications.

“…boiling, which in turn produces complex hydrodynamics, is inevitable. Recent review papers on the boiling heat transfer characteristics of water jet impingement on hot solids [1][2][3][4][5] have revealed that many prior studies on the cooling characteristics of jet impingement focused on hot static solids impacted by water jets at stationary points. As the cooling process for a static solid is apparently different from that in ROT cooling, predicting the actual ROT cooling process requires measurement of the heat transfer to a moving hot solid.…”
