Abstract: As a high efficiency unit of heat transfer, heat pipe is widely applied in many fields. The heat transfer characteristics of the large thermosyphon are studied experimentally in this paper under the near room-temperature. The trend in axial differences in temperature is shown in the paper. Through analyzing the experiment data the article discusses the effects of filling rate，obliquity, length and head-on speed of wind on heat transfer characteristics of the heat pipe. In this condition the optimum filling rate and obliquity are found.
