英文摘要	Oscillating-Flow Heat Pipe (OFHP) is a new type of heat transfer devices, which has an excellent heat transfer performance. In this paper, pulse heating is adopted instead of conventional continuous heating to enhance the heat transfer of this device. Experimental results indicate that the heat transfer rate of pulse heating of OFHP is higher than that of the continuous by 15-38%, and the effective thermal conductivity is higher by 12-63% at the same heating power. There exists an optimal region of heating power for OFHP. To a certain extent, the heat transfer performance of OFHP is reflected by the value of frequency and amplitude of temperature oscillation. In addition, when the heating power was maintained at a constant value, the heat transfer characteristics of OFHP are variable with change of pulse duration and time interval, and both heat transfer rate and effective conductivity have a maximum value. Due to the combined action of internal and external thermal fields, an optimal operating range of pulse duration and time interval may exist.
