摘要
本文从总日射表传感器的热平衡出发,分别对黑白型和全黑型总日射表内各种传热方式随倾角的变化进行了分析和讨论,并得出总日射表内对流换热随倾角的变化是造成倾斜效应主要原因的结论。文中还指出了影响总日射表体内对流换热变化的各项因素,并对黑白型表的倾斜效应大于全黑型表以及首次发现的方位和辐照水准对倾斜效应的影响等原因作了解释。
Inclined effect of several types of pyranometers has been studied according to the conditions of thermal equilibrium.The variation of different modes of heat transfer with inclination angle of white-black and black-body pyranometers are analysed and discussed respectively.The following conclusion is obtained,that the main cause of inclined effect is due to the variation of convective heat transfer with inclination angle.The factors,affecting the variation of convective heat transfer in the pyranometers are considered,and the reasons that inclined effect of black-body type is larger than that of white-black type are explained.Azimuthal and irradiation influences upon inclined effect are discovered for the first time and the interpretation of them are presented.
