摘　　要：根据槽式太阳能热管接收器的工作特点,建立了用于模拟槽式太阳能热管接收器工作条件的半壁加热试验系统,对30%充液量的萘热虹吸管在不同倾角(4°与8°)、不同受热方式(下半壁受热与侧半壁受热)及不同管内蒸汽温度(250℃,300℃,350℃和380℃)条件下进行试验,热管传输功率满足设计要求,具有较好的传热性能。与传统接收器相比,使用热虹吸管为传热元件的热管接收器产生的周向温差将更小,可避免因周向温差过大引起的接收器破坏失效。A half wall heating experiment system was established to simulate the working conditions of solar parabolic trough heat pipe receiver according to its working characteristics. The naphthalene thermosyphon with 30% liquid filled content was tested respectively in two inclination angles （4° and 8°）, in two heating ways （inferior half wall heating and side half wall heating）, and with different steam temperatures in the pipe （250℃, 300℃, 350℃ and 380℃）. The heat pipe has good heat transfer performance, and its transmission power can meet the design requirement. Compared with traditional solar receivers, the heat pipe receiver using thermosyphon as heat transfer component has smaller circumferential temperature difference, which can avoid the damage failure caused by the large circumfer- ential temperature difference.
