Description

Solar collector heating glass

technical field

The utility model relates to solar energy utilization, in particular to a double-layer vacuum solar heat collecting and heating glass. the

Background technique

At present, the commercially available vacuum glass is made of two pieces of transparent glass, the interlayer is hollow, and the hollow layer is evacuated into glass. The interlayer vacuum has good sound insulation and heat insulation functions. Windows and curtain walls are equipped with double-layer vacuum glass, which can be well insulated and warm, and has a good energy-saving effect. But its function is limited to sound insulation and heat preservation. the

The purpose of the utility model is to provide a kind of solar heat collecting and heating glass which utilizes double-layer vacuum glass and solar heat absorbing coating to realize the goal of heat collecting and heating. the

The solution to realize the purpose of this utility model is to improve the heat absorption technology of the vacuum tube solar water heater on the basis of double-layer vacuum glass. The flat glass 1 of the solar heat collecting and heating glass is transparent glass, and the vacuum interlayer 2 is evacuated. The surface of the heat-absorbing glass 3 facing the vacuum interlayer 2 is coated with a solar heat-absorbing coating. The sunlight shines on the solar heat collecting and heating glass, the sunlight passes through the flat glass 1 and the vacuum interlayer 2, and shines on the heat-absorbing glass 3 coated with heat-absorbing coating, and the heat-absorbing glass 3 absorbs the solar energy and can be heated Heat-absorbing glass 3, to achieve the goal of heat collection and heating. Since the vacuum interlayer 2 is a vacuum layer, it has a good heat insulation function and can effectively prevent heat loss from one side of the flat glass 1 . Installing solar thermal heating glass on walls, windows or glass curtain walls can effectively collect solar energy for indoor heating, and achieve energy saving and sound insulation goals. the

If thermal insulation box is installed on the heat-absorbing surface 3 one sides of solar heat collecting and heating glass, just can be made into solar appliances such as solar air heating heat collector, solar drier, and purposes are extensive. the

Detailed ways

The solar heat collecting and heating glass is made of two flat glass double-layer vacuum glass, the flat glass 1 is transparent glass, the interlayer hollow layer 2 is evacuated, and the surface of the heat-absorbing glass 3 facing the vacuum interlayer is coated with a solar heat-absorbing coating. The periphery of the double-layer vacuum glass is welded and sealed. The sunlight shines on the solar heat collecting and heating glass, and the sunlight passes through the flat glass 1 and the vacuum interlayer 2, and shines on the heat absorbing glass 3, and the heat absorbing glass 3 absorbs the sunlight energy, and then heats the heat absorbing glass 3 to realize heat collection Heating target. Since the vacuum interlayer 2 is a vacuum, it has a good heat insulation function and can effectively prevent heat loss from one side of the flat glass 1 . the

Solar heat collecting heating glass can be made into different specifications according to needs. Install double-layer vacuum solar collector heating thermal glass on walls, windows or glass curtain walls and roofs, which can effectively collect solar energy for indoor heating, and achieve energy saving and sound insulation goals; Installing the insulation box can make extended products such as solar air heating collectors, solar dryers, etc., and develop more extensive uses. the
