Embodiment Construction
[0025] The pressure-bearing vacuum flat solar collector 18 of the present invention is mainly composed of a glass cover plate 1, an end baffle plate 2, a bottom plate 13, a perfusion fan 3, a side baffle plate 4, a check air valve 6, a bottom insulation layer 12, and a side insulation layer. 14. The heat collecting plate 15, the heat transfer tube 11, the aluminum tube strip 10, and the heat transfer fin 16 are composed. Glass cover plate 1 is made of upper glass cover plate 8, lower glass cover plate 9, bead 7 and sealing strip 5 around. There are several heat pump working fluid passages 17 on the aluminum pipe strip 10 .
[0026] The heat loss of the vacuum flat plate collector is mainly concentrated in the heat transfer to the surrounding air through the vacuum glass cover plate 1 . In order to reduce heat transfer. The main measure in this design is to evacuate between the two glass plates, which reduces the heat loss of the heat collecting plate 15 to the environment. ...
