Abstract: Heat transfer applications are most investigative area with the evolution of microchips in electronics field; thermal equilibrium maintenance becomes a challenging task in heat pipes because of their reliability, simple structure as well as cost. Heat pipe is one of the well-known heat transfer devices, can transport large quantity of heat from one place to another without any additional power. Working fluid has its role on performance on the basis of its conductivity, because heat pipes have high thermal conductive nature. This review focuses on the submission of Nano-fluids in place of conventional fluids used in heat pipe. This paper reveals the research on thermosyphons, heat pipes and oscillating heat pipes, for reduction in thermal resistance, enhancing the thermal efficiency and heat transfer coefficient of a heat pipe. Various input parameters and their ranges those affect the performance of heat pipe like heat input, angle of inclination, filling ratio, Nano-particle material, size, shape and concentration of Nano-fluid, considered in different studies has been reviewed.
Keywords: Nano Fluid Applications, Heat Pipe, Conductivity, Heat Transfer, Thermal Resistance, Heat Transfer Coefficient.
Scope of the Article: High Performance Concrete
