作为上述技术方案的优选，所述排雨通道的轮廓与所述折射槽的截面轮廓相同，即所述折射槽与所述集雨槽的接触面除底端外全部联通。Preferably, the outline of the rain exhaust passage is the same as the cross-sectional contour of the refraction groove, that is, the contact surface of the refraction groove and the rain collecting trough is all connected except the bottom end.
作为上述技术方案的优选，所述集雨槽的底部设置有散热翅片，所述散热翅片底端开设有透水孔。 Preferably, in the above technical solution, the bottom of the rain collecting trough is provided with heat dissipating fins, and the bottom end of the heat dissipating fin is provided with a water permeable hole.
