The heat transfer device adopts the blue film heat absorber, the heat conduction efficiency is high, and the heat transfer flow channel adopts a copper pipe, so that the heat transfer device is corrosion-resistant, clean and sanitary; the argon arranged in the cavity can avoid the internal fog condensation and liquid condensation caused by the internal and external temperature difference, improve the heat collection efficiency of the heat collector and prolong the service life.

The surface of the low-iron cloth grain toughened glass is of a curved surface structure protruding outwards, and an inorganic nano-silicon super-hydrophilic self-cleaning coating layer is arranged on the outer side of the low-iron cloth grain toughened glass. The curved surface design protruding outwards can improve the absorption rate of absorbing sunlight and has better light collection capability; meanwhile, as the solar thermal collectors are arranged outdoors, dust, rainwater and the like can be attached to the outer surface of the glass cover plate 1, the sunlight absorption rate is influenced, and the influence of the dust and the rainwater on the glass cover plate 1 can be reduced through the arrangement of the inorganic nano silicon super-hydrophilic self-cleaning coating layer, so that the sunlight absorption rate is improved.
