PURPOSE: To enable to transport working fluid without providing outer moving parts by a method wherein two electrodes connected with thermocouples and an N pole and an S pole are provided at the outside of a heat pipe near the condensing side so as the direction of electromagnetic power becomes towards the evapolation side of the heat pipe.
CONSTITUTION: Electrodes 1, 2 are welded at the confronting barrel side of the cross section of a heat pipe 6. Thermocouples 3, 4 are connected to the electrode 1, 2. The thermocouple 3 is placed at a heating part (evapolation side) 7, and the thermocouple 4 is placed a little separated position, at the low temperature place of a cooling part (condenser side) of the heat pipe 6. A permanent magnet 5 is provided surrounding the heat pipe 6, at the same cross section with the electrodes 1, 2. The n and S poles of the magnet 5 are arranged so as the direction of the electromagnetic power generated by the polarity of the electric current between the electrodes 1, 2 connected to the thermocouples 3, 4 and the magnetic line of force between the poles N, S of the magnet 5, is directed towards the evapolating side 7 of the heat pipe 6.
