Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, in particular to a packaging frame and a photovoltaic component. Background Art
[0002] Photovoltaic modules are mainly composed of panels, films, battery bodies, back panels, frames, etc. At present, the frames are mainly made of aluminum, and there are also composite frames and steel frames. The main materials of composite frames are glass fiber, polyurethane, etc., and the main materials of steel frames are aluminum, magnesium, zinc, etc.
[0003] Among them, aluminum frames are easy to process, and it is easy to achieve high-precision size and shape of the overflow groove part. Because the aluminum frame has an overflow groove design, when the laminate is assembled with the aluminum frame, the overflow groove of the aluminum frame can accommodate excess silicone, reduce the overflow of silicone outside the frame groove, and the overall overflow effect is good; however, the high cost of aluminum frame materials leads to limited design thickness of aluminum frame cross section, and the overall thickness is thin. When the assembled photovoltaic modules are actually used, the frame often tears and other phenomena. Composite material frames have low density, better insulation, chemical resistance, and resilience than aluminum, but composite material frames have low hardness, low recycling value, and composite material frames may still need to be tested in terms of lightning protection. Steel frame materials have low cost and high hardness, but steel frames are difficult to process and have low dimensional accuracy. In addition, because the bending modulus of steel is 7 times that of glass, there is a risk of bursting of panels such as glass plates on photovoltaic modules under rapid wind pressure.
