Heat insulating glass curtain

The utility model provides a heat insulating glass curtain belongs to the curtain field, it has solved the problem that the internal heat production of current photovoltaic curtain externally produced the light pollution. The utility model discloses an interior toughened glass, outer toughened glass and solar cell panel, interior toughened glass and outer toughened glass are equipped with interlayer no. 1 and interlayer no. 2 respectively with solar cell panel interval setting respectively, be equipped with hollow parting bead and the hollow parting bead down gone up in interlayer no. 1 and the interlayer no. 2 respectively, it is higher than parting bead position down to go up the parting bead position, it is equipped with water inlet and delivery port respectively with lower parting bead top to go up the parting bead bottom, still including establishing the hollow glass pipe in interlayer no. 1, glass pipe one end opening is connected with the water inlet, the glass pipe other end seals, be connected with a plurality of capillaries on the glass pipe pipe wall, the capillary passes solar cell panel and the outer toughened glass of perpendicular orientation sets up, go up parting bead and parting bead down respectively with the inlet tube with go out water piping connection. This curtain can be internally thermal -insulated, externally reduces the light pollution.
