A new thermosyphon for the use in the non-gravity field has been proposed by using a magnetic fluid as a working fluid. The heat transport of the thermosyphon is driven by a magnetic force instead of the gravity force. In order to avoid too much concentration of the magnetic fluid in a heating region, a liquid bypass line is installed between a heating region and a cooling region so that the highly concentrated magnetic fluid flows from the heating region to the cooling region. The perforance of the thermosyphon has been evaluated based on an analytical estimate of total pressure rise and loss through the magnetic fluid loop. Under the conditions of system pressure 0.02 MPa and the fluid temperature 60℃, it has been confirmed that the thermosyphon with the working fluid of a water-base magnetic fluid has the heat transport capacity of 100 W with the circulation force of 3500 Pa.
