Embodiment 1

[0044] Such as figure 1 with Figure 2a As shown, a solar PV / T building-integrated curtain wall component of this embodiment is a water-cooled module (hereinafter referred to as a water-cooled BIPV / T module), which includes a solar panel 2 and a heat exchange unit in sequence from outdoor to indoor. and insulation layer 3. Wherein the solar cell panel 2 is located at the outdoor side to absorb solar energy, and is composed of a solar cell panel, the material is a monocrystalline silicon battery, and placed vertically. The heat exchange unit includes 6 micro-heat pipe arrays 4 and heat-taking pipes 5. Each micro-heat pipe array 4 is an integrally extruded metal plate structure with arrays of micro-heat pipes arranged side by side, with an average of 2-40 micro-heat pipes per 1 cm. As for the micro heat pipes, one side plane of each micro heat pipe array 4 is attached to the back plate of the solar cell panel 2 , and the top of the opposite side plane is horizontally attached ...

Embodiment 2

[0051] Such as Figure 2b As shown, this implementation is also a water-cooled BIPV / T module. The difference from Example 1 is that, according to the different requirements for the appearance of the building curtain wall, the battery panels are placed horizontally or obliquely, and the micro heat pipe array 4 is 5 pieces. The array 4 is inclined at a certain angle along the horizontal direction. In order to ensure the normal operation of the micro heat pipe, the inclination angle should not be less than 1°. In this embodiment, it is 10°. On the other side of the junction box, that is, the condensation section 9 is placed vertically to obtain heat. water pipe7. In addition, the water-cooled BIPV / T module of this embodiment also includes an interior decoration layer, which is attached to the indoor side of the insulation layer 3, and the interior decoration layer can be decorative substances such as stickers that play an aesthetic role.

Embodiment 3

[0053] This embodiment can be based on embodiment 1 or embodiment 2, the difference is that in order to increase the heat exchange efficiency, the hot water pipe 7 is set as a flat sink type cold water pipe 10 . Such as Figure 5 As shown, the main body of the flat trough cold water pipe 10 is extruded or stamped from an aluminum alloy and has an array structure of ten branch channels 11 arranged side by side along the length direction of the water pipe. Each of the two ends of the structure has a rectangular end cover 12 with a circular dry pipe 13, and the end cover 12 is sealingly connected with the two ends of the main structure, and each branch channel 11 is connected in the end cover 12. The side surfaces of each end cover 12 are connected to the main pipe 13 respectively, and are arranged diagonally, with low entry and high exit, so that the water in each branch channel 11 can converge into the main pipe 13. The internal equivalent diameter of the branch channel 11 is ...

Abstract

The invention discloses a novel solar PV / T building integration curtain wall component and a multi-energy-complementary energy supplying system. The curtain wall component comprises a solar photovoltaic cell panel, a heat exchanging unit and a heat insulating layer which are attached to each other from outdoors to indoors. A load bearing framework is arranged in the heat insulating layer. The heatexchanging unit comprises a micro-heat-pipe array and a heat getting pipe; the micro-heat-pipe array internally comprises a plurality of communicated micro heat pipes arranged side by side and complementarily communicated, and is internally provided with phase change media, one surface of the micro-heat-pipe array is attached to a back board of the cell panel, and one end of the other side of themicro-heat-pipe array is attached to the heat getting pipe; the section, attached to the heat getting pipe, of the micro-heat-pipe array serves as a condensing section, and the other part of the micro-heat-pipe array serves as an evaporating section; fluid is arranged in the heat getting pipe, and one surface of the heat insulating layer is attached to the back faces of the heat getting pipe andthe evaporating section of the micro-heat-pipe array. The assembly has the heat-electricity joint supplying, heat insulation and loading bearing functions, directly serves as a building-outer-wall enclosing structure component, replaces a building outer wall, and has the advantages that the maintenance cost is reduced, the temperature of the cell panel is lowered, electricity generation efficiencyis improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a new type of solar PV / T building-integrated curtain wall component, which replaces the traditional wall and directly serves as a building envelope structure component, and realizes the complementary cascade utilization of thermoelectric and other energy sources, and belongs to the field of light-building integration and energy saving. Background technique [0002] At present, the conventional photovoltaic curtain wall is usually designed on the outside of the outer wall of the original building envelope structure. A photovoltaic power generation system in the form of a curtain wall connected to the outer wall through the supporting structure at intervals. The composition structure from the outer surface of the building to the interior is as follows: Photovoltaic curtain wall, cavity, building exterior wall, indoor environment. The working principle is: the cold air in the room continuously enters the cavity to absorb the heat ...
