建立了热管传热性能测试装置,通过实验得到了不同方向、不同强度磁场作用下磁流体工质热管传热性能的变化规律,并采用场协同原理对磁流体在磁场作用下的自然对流特性进行了分析与研究.结果表明:磁流体工质热管的传热性能不仅与磁场的强度有关,而且与磁场的方向有关;磁场对热管蒸发段磁流体自然对流强度的影响是导致热管传热性能变化的主要原因. The heat transfer performance test device of the heat pipe was established. The variation of the heat transfer performance of the heat pipe of the working fluid in different directions and different intensities was obtained by experiments. The natural convection characteristics of the magnetic fluid under the action of magnetic field The results show that the heat transfer performance of the heat pipe is not only related to the strength of the magnetic field but also to the direction of the magnetic field. The influence of the magnetic field on the natural convection strength of the heat pipe is caused by the change of heat transfer performance The main reason.
