[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figure 1-Figure 2 As shown, a building solar integrated photovoltaic thermal device consists of a heat conducting frame 1 and a heat storage back cover 3;

[0018] The solar panel 2 is installed on the top of the heat-conducting frame 1, and the heat storage back cover 3 is fixedly installed on the bottom of the heat-conducting frame 1. The bottom of the heat storage back cover 3 is installed with an angle adjustment assembly frame for adjusting the tilt angle of the solar panel 2 to maximize the reception of sunlight;

[0019] A heat-conducting layer 14 is installed inside the heat-conducting frame 1. After sunlight is projected onto the solar panel 2, a small portion of the energy is converted into electrical energy through the photoelectric effect, and most of the energy exists in the form of heat. The heat-conducting layer 14 is transferred to the heat storage back cover 3, which can reduce the diffusion of heat.

[0020] A mesh liquid medium pipe group 15 is installed on one side of the heat storage back cover 3 close to the heat conductive layer 14. The mesh liquid medium pipe group 15 is composed of crisscross and interconnected pipes, and a liquid medium is provided inside for transferring heat. A discharge end joint 9 and a return end joint 10 are fixedly installed on the cover shell of the heat storage back cover 3. The discharge end joint 9 and the return end joint 10 are both connected to the mesh liquid medium pipe group 15 to realize the circulation of the liquid medium. The discharge end joint 9 is connected to the heat exchange assembly 8 through the transmission pipe 12. The heat exchange assembly 8 is connected to the circulation pump 7 through the transmission pipe 12. The circulation pump 7 pipe is connected to the return end joint 10.

[0021] like Figure 1-Figure 2 As shown, the present invention also discloses the following multiple more optimized specific structures:

[0022] A light intensity detection assembly 11 is fixedly mounted on the outer side of the heat conducting frame 1 , and a controller 13 is fixedly mounted on the outer side of the heat storage back cover 3 . The controller 13 is in communication connection with the light intensity detection assembly 11 to facilitate light intensity detection.

[0023] A temperature sensor 33 is installed on the inner cover wall of the heat storage back cover 3 , and the temperature sensor 33 is in communication connection with the controller 13 .

[0024] The angle adjustment assembly consists of an electric cylinder 4, a bracket 5 and a base frame 6. The bottom of the bracket 5 is fixedly mounted on the base frame 6, the top of the bracket 5 is hinged to the bottom of the heat storage back cover 3, the bottom end of the electric cylinder 4 is hinged to the base frame 6, and the top end of the electric cylinder 4 is hinged to the heat storage back cover 3 to achieve angle adjustment.

[0025] The heat storage back cover 3 is a double-layer structure, consisting of an inner heat insulation layer 32 and an anti-oxidation and corrosion layer 31 arranged on the outer side of the inner heat insulation layer 32 .

[0026] The circulation pump 7 is fixed on the heat storage back cover 3 .

[0027] like Figure 1-Figure 2 The shown building solar integrated photovoltaic thermal device is mainly installed on the top of the building. The light intensity of each angle of the heat conducting frame 1 is monitored by the light intensity detection assembly 11. The electric cylinder 4 is telescopically adjusted to various angles, so that the solar panel 2 can be adjusted according to the sunlight projected at different time periods, and the light is projected perpendicular to the solar panel as much as possible. Most of the heat is introduced to the back side through the heat conducting layer 14 and the heat is transferred out through the mesh liquid medium group pipe 15. When the temperature sensor 33 detects that the temperature is too high, the circulation pump 7 increases the power to circulate the liquid medium, so that the heat is transferred out through the heat exchange assembly 8.

[0028] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
