Research on Water Based Nano Fluids Effecting Thermal Performance of Heat Pipe

Heat transfer applications are most investigative area with the evolution of micro chips 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 device, 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 researches 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.
