As shown in figure 24, among this embodiment, the intersection of wing plate 42 and absorber plate 11 or 12 and the angle D2 of horizontal plane are between ± 15 °.
As shown in figure 25, floor building sides Southern Dynasties north trend, top, roofing slope is " people " font.On the top, roofing slope 1 of sunny slope, has solar thermal collector 30.Wing plate 42 is absorber plates that the surface scribbles high solar absorptivity coating.The direct light of direct irradiation on absorber plate and fin 42, the heat of scattered light 91 are directly absorbed by absorber plate and fin 42.
Top, roofing slope 1 ' at opaco has solar thermal collector 30 '.Wing plate 42 ' surface is the high reflection mirror face.Direct light, the scattered light 91 ' of direct irradiation on absorber plate and wing plate 42 ' reflexes on the absorber plate through the high reflection mirror face of wing plate 42 ', absorbed the heat that transmits by absorber plate.
In addition, as seen from the figure, during this was used, the wing plate 42 ' of the solar energy heat collection pipe 30 ' of opaco was widened gradually by under last, so as the fore wing plate fully block sunlight shine on the wing plate of back, thereby the thermal efficiency of raising solar energy heat collection pipe.
