“…This resulted in 80 and 20% higher heat transfer coefficient (HTC) for CVD grown graphene and fluorinated-graphene coatings as compared to the plain copper surface (HTC = 5.3 kW/m 2 K). However, due to the increased bubble density, the CHF for CVD grown fluorinated-graphene coating is 370 kW/m 2 , which is lower than the plain copper surface (CHF = 380 kW/m 2 ), while CVD graphene shows the highest CHF of 428 kW/m 2 [6].…”

Pool boiling heat transfer has proven to be the most effective ways to dissipate the large amount of heat fluxes and achieve the efficient cooling in many industrial applications including high-power electronics cooling, data center cooling, heat exchangers, batteries, refrigeration, and air conditioning. With the aggressive net-zero carbon footprint goals set up by the numerous industries across the globe, the need for development of innovative two-phase cooling solutions is of utmost importance. Graphene, being the highest thermal conductivity material, has been implemented in numerous studies for improving both the critical heat flux (maximum possible heat removed before thermal runaway of the heater surface) and a heat transfer coefficient (determines how efficiently the heat is removed) in pool boiling heat transfer. Initially, this chapter introduces various graphene-based nanomaterials and basics related to structure and characterization of graphene. Later, the highlights of some of the notable research work related to the graphene-based coatings for pool boiling enhancements are discussed. The responsible mechanism for such higher performance is summarized. Concluding remarks and industrial applicability of these techniques are also discussed in this section.
