OPEN ACCESS
Based on the author’s previous related research and numerical simulation, in this paper the experimental study and theoretical analysis were conducted about the heat transfer characteristics of ordinary heat pipe and water-based magnetic fluid heat pipe under the DC magnetic field by combining the unique properties of magnetic fluid and magnetic field in heat transfer, to verify another new technology and improve the heat transfer enhancement of heat pipes. The comparative experimental results show that under the action of DC magnetic field, the heat transfer performance of the two pipes is directly proportional to the applied magnetic field strength; when the strength of the applied DC magnetic field is 150Gs, the heat transfer rate of the magnetic fluid heat pipe is increased by 15% more than that with no magnetic field; the heat transfer rate of the ordinary water heat pipe is increased by 9% more than that with no magnetic field.
