Experimental Study on Convection Heat Transfer Characteristics of Magnetic Nano-Refrigerant

Article Preview

Abstract:

An experimental system of Fe3O4-R600a magnetic nanofluid on thermo-magnetic convection characteristics of a cooling device using magnetic nanorefrigerant was prsented. The influences of magnetic field distribution and intensity, cooling temperature, heat load were discussed. The experimental results show that the heat was transferred obviously by the circulating fluid with the absence of a pump. The synergic function between the external magnetic field and the thermal field has impact on the velocity of the working fluid and the cooling performance of the device.
