Review of surface modification in pool boiling application: Coating manufacturing process and heat transfer enhancement mechanism

Abstract

• The surface modification methods of coatings commonly used in pool boiling are summarized and evaluated. • The influence mechanisms commonly used for pool boiling are summarized and analyzed. • The influence mechanisms under different heat fluxes are reviewed, including strengthening and weakening. • The CHF prediction models that can be used for coating structure are summarized and prospected. With the development of science and technology, the operating power of equipment is getting higher and higher, and the demand for heat dissipation is also increasing. Therefore, thermal management has become a hot topic in recent years. Boiling heat transfer has been considered as a effective solution for heat dissipation. The effect of boiling heat transfer can be enhanced by increasing the surface microstructure and nanocoating. This is the so-called surface modification technology. This paper divides the coating modification methods into two types: physical methods and chemical methods, for sorting and evaluation. For example, common physical methods include spin coating, magnetron sputtering, and chemical methods include chemical vapor deposition, electrochemical cathode and anode methods. In addition, in order to better predict the heat transfer effects of different structures at different stages, this review summarizes the common boiling strengthening mechanisms, evaluates the surface modification methods applied to pool boiling. Finally, critical heat flux (CHF) prediction models that can be used for nanostructured coatings are summarized.
