Embodiment 1
[0023] refer to figure 1 with figure 2 According to the present invention, it includes a frame 2; one side of the frame 2 is provided with a photovoltaic power generation panel 1 fixedly connected with it, and the other side of the frame 2 is provided with a photothermal heat absorbing plate core 4 fixedly connected with it; the frame 2 The upper end is provided with a photoelectric plug 3 interconnected with the photovoltaic power generation panel 1 .
[0024] The beneficial effect of the present invention is that: the solar-thermal integrated heat collector can reduce the cost by about 20% compared with two independent photovoltaic panels and solar-thermal panels with the same specifications due to the shared part of the structural components; The heat-absorbing plate core is combined to improve the utilization rate of solar energy per unit; after the assembly is completed, the combination of photovoltaic power generation and light heating is realized, which saves producti...
Embodiment 2
[0026] The above-mentioned frame material is prepared according to the following process:
[0027] 1) Mix alumina, quartz sand and potassium feldspar evenly according to the mass ratio of 5:3:1, put them into a ball mill tank, stop ball milling when the powder particle size is 200 mesh, and obtain component A;
[0028] 2) Put sepiolite and brucite into the pulverizer according to the mass ratio of 1:1 for pulverization, then grind them into powder, pass through a 200-mesh sieve to obtain component B;
[0029] 3) Add polyethylene wax, polycarbonate and glass fiber to the mixing tank in turn, stir evenly, then heat to 60°C, add vinyltrimethoxysilane, keep stirring at 60°C for 10min; then cool down to room temperature to obtain the composition Point C; Wherein, the mass ratio of polyethylene wax, polycarbonate, glass fiber and vinyltrimethoxysilane is 3:2:1:2;
[0030] 3) Add component A, component B, component C, polypropylene resin, polystyrene resin, magnesium stearate and ta...
