中文摘要：
本文采用真空集热管在抛物槽式太阳能平台上进行了实验研究,传热工质为YD300型合成导热油。实验测定了该集热管的散热损失,并数值模拟了吸热管表面的能流密度分布。以此为边界条件研究了该集热管的换热性能。结果表明,循环工质温度和环境温度之差为180℃时,散热损失为220 W/m;该集热器吸热管表面圆周方向能流分布集中,流量对温度分布影响较大,当太阳直射辐照为1000 W/m^2,导热油温度为200℃,流量为0.5 kg/s时,吸热管圆周方向最大温差50℃左右,当流量增加到2.0 kg/s时,最大温差减小到20℃左右。
英文摘要：
In this paper,an experiment setup was fabricated to test a new parabolic trough solar receiver,using the synthetic oil-YD300 as the circulate heat transfer fluid.The heat loss of the receiver was tested,and the heat flux distribution of the receiver surface was obtained,which was considered as the boundary condition to simulate the heat transfer performance of the receiver.As a result,the heat loss from the receiver was around 220 W/m at a temperature difference of 180℃between the fluid temperature and the ambient temperature.The temperature distribution of the receiver around the circumference is non-uniform,when the synthetic oil is 200℃with the solar flux of 1000 W/m2,the maximum temperature difference of the absorber decrease from 50℃to 20℃when the flow rate increases from 0.5 kg/s to 2.0 kg/s.
