In order to improve the heat transfer rate of vacuum heat pipe using magnetic nano-fluids as the working medium,a method was proposed by enhancing the heat transfer with outer magnetic field,based on which a series of experimental tests were carried out with outer magnetic fields of different categories and densities.Results show that under various external conditions,the heat pipe of nona-magnetic fluid is better than those of any other magnetic fluids and water fluid in heat conductivity.All kinds of outer magnetic field can enhance the heat transfer rate of nona-magnetic fluid heat pipe,among which the static DC magnetic field enhances the most.
