“…Pool boiling heat transfer (BHT) has been widely in various scientific and technological applications since it was put forward, such as heat pump, heat exchangers, nuclear reactors, electronic cooling, refrigeration, spacecraft avionics and cryogenic system [1][2][3][4][5][6][7][8]. Surface and working fluid modification techniques have been exploited to improve pool boiling performance [9][10][11][12][13]. Various modification techniques used to develop heating surfaces are suitable in pool BHT applications such as RF sputtering, electrodeposition, sintering, soldering, spray painting, binding, microporous coatings and dip coating [14][15][16][17][18][19][20].…”

Pool boiling heat transfer (BHT) of R-141b on porous Cu coated heating surface was experimentally studied. Porous Cu coating was fabricated on a plain Cu heating surface through a two-stage electrodeposition method. Surface characterization of Cu coating confirmed the successful synthesis of micro/nano-porous Cu coating. Experimental results showed that the Cu coated heating surface introduced a significant enhancement in heat transfer coefficient (HTC) and a great reduction in wall superheat compared to the plain Cu surface. The maximum enhancement in HTC for the Cu coated heating surface was approximately 53% compared to the uncoated heating surface. This is believed to have resulted from the increase in active surface area, nucleation site density and cavitation activity owing to the microporous structure of Cu coating. Obtained results showed that the microporous Cu coated heating surface could be employed in modern heat transfer applications.

The present study investigates pool boiling heat transfer (PBHT) of R‐134a on Cu─Al2O3 composite‐coated patterned surfaces (CPSI, CPSII, CPSIII, and CPSIV). Using a wire EDM method, four different types of copper patterned surfaces (PSI, PSII, PSIII, and PSIV) were manufactured. Comparing the heat transfer coefficients (HTCs) of the Cu─Al2O3 composite‐coated patterned surfaces to the uncoated Cu surfaces, a notable enhancement was observed. The maximum HTC improvements of 162%, 178%, 189%, and 211% were observed for CPSI, CPSII, CPSIII, and CPSIV, respectively, when compared with bare Cu surfaces. These results demonstrate the effectiveness of these treatments in enhancing heat transfer compared to bare copper surfaces. The enhancement in PBHT is mainly due to the integration of porous Cu─Al2O3 composite coating with patterned surfaces which resulted in a larger heat transfer area, improved capillary action, and a substantial increase in active nucleation sites.
