A photovoltaic cell and sound-absorbing composite screen using Porous aluminum foam for cooling pv panels . The structure includes an aluminum alloy frame, a Porous aluminum foam for cooling pv panels, a photovoltaic cell panel, and a sound-absorbing inner panel, and is characterized in that the sound-absorbing inner panel is fixed on the bottom surface of the photovoltaic panel, and the mounting grooves around the inner side of the aluminum alloy frame At the same time, the photovoltaic cell panel and the sound-absorbing inner plate are fixed, and the porous aluminum sound-absorbing plate is fixed in the installation groove around the inner side of the other side of the aluminum alloy frame. The space between the sound-absorbing inner plate and the Porous aluminum foam for cooling pv panels constitutes a sound-absorbing cavity. The first is to overcome the shortcomings of not making full use of existing resources, implement overall consideration, integrate resource advantages, maximize the utilization of sound-absorbing screen resources, and reduce the investment cost of independent investment in sound-absorbing screens and photovoltaic cell fields. It breaks through the bottleneck of insufficient land resources for the large-scale development of solar grid-connected power generation in cities, and provides a new mode of using roads as solar power generation to realize a low-carbon economy.
When the noise generated by cars passing on the elevated road is absorbed by the perforated Porous aluminum foam for cooling pv panels located on the inner side of the elevated road, the noise is reduced in the whole process. In addition, the photovoltaic panels facing the sun side generate electricity under the sunlight, and transmit power to the grid through the inverter to supply power to the city. In addition, the generated electricity can also charge the battery to light up the street lights or signs of the elevated road at night.
