摘　　要：本文介绍了一种无毛细吸液芯的碟形平板热管,其内部蒸汽腔高度仅为1 mm,用磁流体作工质,并对其性能进行了实验研究。研究了加热功率、充液率、安置方式等因素对磁流体平板热管性能的影响,并将之与工质为水时的结果进行了比较,证明水工质热管不能正常工作的情况下,磁流体平板热管在外加磁场作用下仍能克服重力的作用而表现出良好的均热性能。In this paper, we prepared a disk-shaped wickless flat plate heat pipe, and the gap between evaporation and condensation surfaces is only 1 mm. From experimental study, the effects of heat flux and working fluid ratio on the performance of flat plate heat pipe are obtained. The experimental results are also compared between the performance of water and magnetic fluid as working fluids.
