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。
According to the operating characteristics of trough solar heat pipe receiver, a half-wall heating test system for simulating the working condition of trough solar heat pipe receiver was established. , Different heating methods (heating of the lower half of the wall and heating of the side half wall) and different tube steam temperatures (250 ℃, 300 ℃, 350 ℃ and 380 ℃) were tested under the conditions of heat pipe transmission power to meet the design requirements, has good heat transfer performance . Compared with the traditional receiver, the thermosiphon used as the heat pipe receiver heat transfer element receiver circumferential temperature difference will be smaller, to avoid the circumferential temperature difference caused by the receiver failure failure.
