Graphene nanosheets have attracted appreciable interest in heat transfer augmentation due to the unique deposition characteristics. The porous morphology of the graphene deposited on the heating surface via self‐assembly is reported to retard the transition boiling significantly. However, less attention has been paid to ameliorate the heat transfer coefficient (HTC) of graphene‐dispersed solutions. Herein, silver ions are introduced into graphene nanofluids to ameliorate its HTC. During boiling, graphene nanosheets and silver nanoparticles simultaneously deposit on the heating surface to form a well‐structured porous graphene/silver hybrid coating. The newly formed surface is characterized for surface morphology, wettability, and roughness. The new surface coating enhances the HTC by up to 109% and maintains the retarded critical heat flux of graphene‐only nanofluids. The application of the enhanced boiling heat transfer for the thermal management of concentrated photovoltaics is studied. It is demonstrated that enhanced boiling allows for cogeneration of electricity and heat from concentrated photovoltaics at approximately fourfold increased production rate while maintaining efficient, safe, and reliable operation.

“…Nanoparticles and nano scale coatings, such as nanowires, nanotubes, nanofibers coating, is another useful method for boiling heat transfer enhancement. [33][34][35][36] Due to characteristics, such as an increase in the nucleation points, enhancement in the surface area 5,37 and roughness, 38 variation of wettability, 39,40 the deposition of nanoparticles causes an enhanced performance. For example nanoparticles act as nucleation points for bubbles and increases the frequency of the bubbles which results lower superheat and high HTC and CHF.…”

Metal particles coating is extensively used for surface coating a wide range of application including thermal management of electronics, concentrating photovoltaics, sensors and nuclear power plants. Both micro and nano-scale surfaces have been proven to show an enhanced two-phase heat transfer performance by varying surface properties like area, wettability, and roughness. To combine the unique features of both micro and nano-scale surface coatings, this study presents the design, synthesis, and characterization of new hybrid micro-nano scale surface coating by a new two steps approach. Five different types of surfaces; namely, plain nanocoated (PNC), uniform microporous (UMP), uniform hybrid micro-nano porous (UHMNP), 2-D modulated microporous (MMP) and modulated hybrid micro-nano (MHMNP) surfaces were fabricated. A new two steps approach of hot-pressing followed by nucleate boiling is used for the fabrication of these surfaces. Successful coating of hybrid micro-nano scale coating was achieved. Considering the critical surface properties of micro and nanoscale coatings, new hybrid micro-nano surfaces have been characterized for SEM, wettability, roughness test. The comparative analysis of these new hybrid coating is also performed with micro coated and uncoated surfaces. With the coating of nanoparticles, the average roughness of PNC surface increased by 4.67 times and that of hybrid micro-nano particle surface by 2.3 times. The deposition of nanoparticles resulted in an increase in contact angle for PNC surface, while the contact angle of hybrid micro-nano surfaces decreases from 126.4 to 82.1 .
