In view of the highly heat exchanger efficient of heat pipe, two vacuum heat pipes of water and Fe3O4-water were prepared and test system was designed to test the heat transfer efficiency of them when they are within and without magnetic field. The experimental results showed that the heat exchange of heat pipe with magnetic fluid was more efficient than the other one. According to the results and combine the physical properties of two kinds of refrigerant, analyze the heat transfer characteristics of the magnetic fluid in magnetic field. |
