摘要: 对含有纳米级磁性微粒的磁性流体应用于热管进行了试验研究,分析了微粒浓度对热管传热性能的影响。试验结果表明,在试验研究的范围内,纳米级磁性颗粒应用于热管后减弱了热管的传热,而且磁性流体热管存在一个最优磁性微粒浓度,该浓度下磁性流体热管的传热性能最好。

Abstract: The application of magnetic fluid with nanometer magnetic particles in heat pipe was studied, and the effect of particle concentration on the heat transfer characteristic of the heat pipe was investigated. The experiment showed that the heat transfer ability of the heat pipe with magnetic fluid receded compared with its carrier liquid within the experimental range, and there was an optimum concentration, in which the heat transfer ability of the heat pipe was best.
