Study on enhanced heat transfer features of nano-magnetic fluid heat pipe under magnetic field

Abstract

In order to enhance heat transfer speed of heat pipes, this paper uses external magnetic field to strengthen heat transfer of nano-magnetic fluid heat pipe. It designs the test rig and conducts experiments on the heat transfer of nano-magnetic fluid heat pipe under the influence of various magnetic fields. The study proves that nano-magnetic fluid heat pipe is superior to magnetic fluid heat pipe and water heat pipe under various circumstances; a variety of magnetic fields can enhance heat transfer of nano-magnetic fluid heat pipe and the static DC magnetic field can best improve the heat transfer speed of heat pipe with the maximum improvement rate of 19.2%.
