以槽式太阳能集热器为研究对象,其中吸收器选用腔体式,通过数值模拟和正交分析的方法,对影响槽式太阳能集热器热效率的主要因素进行分析研究。研究结果表明:6种因素对热效率的影响从大到小依次为:光线沿轴向入射角度、抛物面反射率、光线沿径向入射角度、直接太阳辐照度、吸收器吸收率、抛物面与吸收器距离。
Taking the trough solar collector as the research object, the absorber is selected as the cavity type, and the main factors affecting the thermal efficiency of the trough solar collector are analyzed through numerical simulation and orthogonal analysis. The results show that the influence of the six factors on the thermal efficiency is as follows: the incident angle of light along the axis, the parabolic reflectance, the incident angle of light along the radial direction, the direct solar irradiance, the absorptance of the absorber, the paraboloid and the absorption Distance of the device.
