[0010] This utility model of a hail-resistant solar thermal collector that generates electricity is achieved through the use of a cadmium telluride (CDT) power-generating glass plate located above the outer tube. This CDT not only generates electricity by converting solar energy into electrical energy but also protects the outer and inner tubes below from damage by hail. A reflector located below the outer tube reflects sunlight upwards onto the downward-facing surfaces of the outer tube and the CDT, significantly improving the heat collection efficiency. The CDT, reflector, and multiple sealing plates form a heat storage cavity to seal the outer tube, further enhancing the heat collection efficiency. Therefore, this utility model of a hail-resistant solar thermal collector that generates electricity utilizes solar energy, preventing damage to the double-layered vacuum tubes of the solar thermal collector while simultaneously improving its heat collection efficiency.

[0014] like Figure 1 and Figure 2 As shown, the solar thermal collector for generating electricity and preventing hail includes multiple outer tubes 1 arranged side by side, an inner tube 2 inside the outer tube 1, a vacuum cavity 3 between the outer tube 1 and the inner tube 2, a cadmium telluride power-generating glass plate 7 above the outer tube 1, and a reflector 8 below the outer tube 1. The reflector 8 can reflect sunlight upwards to the downward-facing surfaces of the outer tube 1 and the cadmium telluride power-generating glass plate 7. The side of the cadmium telluride power-generating glass plate 7 is connected to the side of the reflector 8 by multiple sealing plates 9. The cadmium telluride power-generating glass plate 7, the reflector 8 and the multiple sealing plates 9 form a heat storage sealing cavity 11 for sealing the outer tube 1. The cadmium telluride power-generating glass plate 7, the reflector 8 and the multiple sealing plates 9 are installed and fixed on a bracket 6.

[0015] As a further improvement of this utility model, one end of the inner tube 2 is connected to the refrigerant manifold 4, one end of the refrigerant manifold 4 is provided with a cold air inlet 12, the other end of the inner tube 2 is connected to the hot medium manifold 5, one end of the hot medium manifold 5 is provided with a hot air outlet 13, and the refrigerant manifold 4 and the hot medium manifold 5 are installed and fixed on the bracket 6.

[0016] As a further improvement of the utility model, the fan 14 is arranged at the cold air inlet 12 or the hot air outlet 13. The fan 14 can be driven by the power generated by the cadmium telluride power generation glass plate 7. When the fan 14 is turned on, the hot air in the inner tube 2 flows into the heat medium header 5, and then is delivered to the indoor through the hot air delivery pipeline, so as to increase the indoor temperature or heat water. At the same time, the cold air in the refrigerant header 4 flows into the inner tube 2, is heated by the solar energy, and then flows into the heat medium header 5.

[0017] As a further improvement of the utility model, the reflector 8 is made of a steel plate, the surface of the steel plate facing the outer tube 1 is paved with a heat insulation plate or a heat insulation layer, and the surface of the heat insulation plate or the heat insulation layer facing the outer tube 1 is paved with an aluminum foil film for reflecting light.

[0018] As a further improvement of the utility model, the sealing plate 9 is made of the cadmium telluride power generation glass plate 7.

[0019] As a further improvement of the utility model, the sealing plate 9 is made of the cadmium telluride power generation glass plate 7.

[0020] In use, the cadmium telluride power generation glass plate 7 is arranged above the outer tube 1. The cadmium telluride power generation glass plate 7 can not only generate power and convert solar energy into electric energy, but also protect the outer tube 1 and the inner tube 2 below the cadmium telluride power generation glass plate 7 from being damaged by hail. The reflector 8 arranged below the outer tube 1 can reflect the sunlight upward to the downward surface of the outer tube 1 and the downward surface of the cadmium telluride power generation glass plate 7, so as to greatly improve the heat collection efficiency of the hail-proof solar hot air collector. The cadmium telluride power generation glass plate 7, the reflector 8 and the plurality of sealing plates 9 form a heat storage sealing cavity 11 for sealing the outer tube 1, so as to further improve the heat collection efficiency of the hail-proof solar hot air collector. In addition, since the outer tube 1 is sealed in the heat storage sealing cavity 11, the dust in the outside environment cannot directly fall on the outer tube 1 with a circular cross section, but falls on the cadmium telluride power generation glass plate 7 with a planar shape, which is easier to clean. Therefore, the hail-proof solar hot air collector with power generation function has the characteristics of preventing the hail from damaging the solar hot air collector with double-layer vacuum tubes, generating power by using solar energy, and further improving the heat collection efficiency of the solar hot air collector.
