[0023] A solar power generation and heating integrated device of the present invention, such as Figures 1 to 6As shown, a photovoltaic solar cell 2 and a photovoltaic assembly 11 electrically connected thereto are provided for photovoltaic power generation, which is a prior art well known to those skilled in the art, and its mechanism and principle are not described in detail here. A frame 1 is also provided, and the photovoltaic solar cell 2 is embedded in the front side of the frame 1, and the photovoltaic solar cell 2 closes the front side of the frame 1. A back plate 6 is fixedly provided on the rear side of the frame 1, and the back plate 6 closes the rear side of the frame 1. The photovoltaic assembly 11 is fixedly provided on the side of the back plate 6 away from the photovoltaic solar cell 2.

In this way, the heat storage medium heated by solar energy will rise from the heat conducting pipes 3 and gather in the water storage cylinder 5, so that the temperature of the heat storage medium in the water storage cylinder 5 becomes higher and higher, thereby achieving heating. In order to circulate the heated heat storage medium in the water storage cylinder 5 in and out, a first medium pipe 7 connected to the water storage cylinder 5 is provided on the left side thereof, and a second medium pipe 8 connected to the water storage cylinder 5 is provided on the right side thereof.

Because the photovoltaic solar sheet 2 and the photovoltaic assembly 11 electrically connected thereto of the present application device perform photovoltaic power generation, and a heat conducting pipe 3 is provided on the rear side of the photovoltaic solar sheet 2 for heating, the utilization rate of solar energy is improved, and space is saved. The utilization rate of solar energy per unit area can reach 75-80%. At the same time, the water storage cylinder 5 and the heat pipe 3 are placed in the placement chamber surrounded by the photovoltaic solar panel 2, the frame 1 and the back plate 6. For places in the north where the temperature is low at night, the risk of the water storage cylinder 5 and the heat pipe 3 being frozen is effectively reduced, and the adaptability of the product is improved. In addition, the heat pipe 3 is arranged at the rear side of the photovoltaic solar panel 2, which has the effect of cooling and protecting the photovoltaic solar panel 2. It is found in actual application that it can greatly extend the life of the photovoltaic solar panel 2.
[0024] Preferably, in order to keep the heat conducting pipe 3 warm, the placement chamber between the back plate 6 and the heat conducting pipe 3 is filled with a heat insulating material 4. The heat insulating material 4 can be selected from commercially available heat insulating materials, such as heat insulating cotton or glass fiber.

[0027] Preferably, in order to control the system to start or stop the heat storage operation, the first pipeline 15 is installed with a second valve 20, and the second pipeline 16 is installed with a first valve 19.
[0028] Preferably, the heat storage medium will be lost when it circulates in the system. In order to replenish the heat storage medium, a liquid replenishment tank 12 is also provided. The liquid replenishment tank 12 contains the heat storage medium. A liquid adding pipe 10 connected to the water storage cylinder 5 is provided at the top. The end of the liquid adding pipe 10 away from the water storage cylinder 5 passes through the frame 1 and extends out of the water storage cylinder 5. The liquid adding pipe 10 is connected to the liquid replenishment tank 12 through a fourth pipe 18. The fourth pipe 18 is installed with a fourth valve 22. When in use, the fourth valve 22 is opened to replenish the heat storage medium to the water storage cylinder 5.
[0029] Preferably, in order to ensure smooth operation of the system, the air in the system should be emptied in time. For this purpose, an exhaust pipe 9 connected to the water storage cylinder 5 is provided on the top of the water storage cylinder 5. The exhaust pipe 9 passes through the frame 1 at one end away from the water storage cylinder 5 and extends out of the water storage cylinder 5.
