Description

technical field [0001] The invention belongs to the technical field of photovoltaic and building integration, and specifically relates to a solar curtain wall integrated with photovoltaic building. Background technique [0002] Photovoltaic buildings generally use integrated solar curtain walls, solar curtain walls, as the name implies: a device that uses solar panels for photovoltaic conversion power generation. Photovoltaic curtain walls are glass walls composed of core components such as glass and solar panels, and are installed through aluminum alloy mounting parts. On the surface of photovoltaic buildings, it can not only effectively insulate the interior of the building, but also convert solar energy into electrical energy for social use. It is an environmentally friendly building exterior wall accessory.

AI Technical Summary

Problems solved by technology

[0003] The existing building-integrated photovoltaic solar curtain wall mainly uses sunlight to directly shine on its built-in solar thin-film battery panel, and directly converts solar energy into electrical energy through the solar thin-film battery panel. Therefore, it has a common problem: heat, the sun Light is not 100% converted, and a large part of the sunlight is reflected. Since the sunlight has radiation, it will cause the temperature of the solar curtain wall to rise, thereby affecting the operation of the solar cells inside. The existing solution is to convert the solar energy The curtain wall is set to be hollow, and then the heat is taken away by the air flow through the active heat dissipation equipment; but this method has great defects: first, the structure is complex and the cost is high, and the space of the solar curtain wall cannot allow heat dissipation equipment, and there are no conditions for heat dissipation channels Second, the solar curtain wall is originally installed in the high-rise position of the building. The surrounding air flow at this height is very fluid, and there is no need for active cooling equipment at all; third, it cannot automatically dissipate heat, and the existing active cooling equipment cannot automatically sense The heat generation of the solar curtain wall does not need to be dissipated in many cases. Therefore, a solar curtain wall that can realize the automatic heat dissipation function is needed

[0004] At present, BIPV solar curtain wall has another function, that is, heat insulation, which protects the interior of the building from solar radiation by reflecting sunlight and prevents the indoor temperature from rising due to sunlight, but this design is only suitable for summer. In winter, the heat generated by the solar curtain wall can completely supply the interior of the building, reducing the heating cost of the building. However, in the prior art, the solar curtain wall only focuses on heat dissipation, resulting in the overall structure being completely isolated from the interior. state, so that the heat generated by solar energy is wasted and cannot be effectively supplied to the room. The waste of heat is also another form of pollution, which needs to be solved urgently.

[0005] Existing building-integrated photovoltaic solar curtain walls mainly rely on aluminum alloy metal frames for installation and fixing. Aluminum alloy is a light metal alloy, and its strength and cost need to be balanced before it can be used. In the prior art, building integrated photovoltaics After the solar curtain wall is installed, it will exert a lot of force on the aluminum alloy metal frame, but the force point cannot be effectively grasped during the installation process, which will easily cause fatigue and bending deformation of the aluminum alloy metal frame, which will affect the normal use of the solar curtain wall
