OPEN ACCESS
In order to improve the heat transfer rate of heat pipe, an experimental research method was introduced, it is that using magnetic field to enhance the heat transfer of nano-magnetic fluid vacuum heat pipe. In this experiment, through the preparation of nano-magnetic fluid as well as the independent design the heat exchanger test-bed, the heat transfer of nano-magnetic fluid heat pipe was studied in different types and intensities of magnetic fields. The study found that the heat transfer of nano-magnetic fluid heat pipe was the best. Every kind of magnetic field could enhance the heat transfer of nano-magnetic fluid heat pipe, in which the static DC magnetic field did the best and the maximum raise rate was 19.2%.
