[0015] 1. This utility model incorporates a heat dissipation component, which includes a hydrophilic gel core, a first heat sink, a graphene composite film, a heat dissipation layer, a second heat sink, and a super-dihydrophobic radiation-reducing coating. In use, the hydrophilic gel core is embedded within the composite thermally conductive layer, allowing for heat absorption through phase change and reducing temperature rise. The first heat sink improves heat dissipation efficiency. The graphene composite film covering the surface of the heat dissipation layer enhances thermal radiation efficiency, achieving efficient cooling. The heat dissipation layer has a honeycomb structure, which increases surface area and strengthens convective heat dissipation. The second heat sink further improves heat dissipation efficiency. The super-dihydrophobic radiation-reducing coating, a composite structure of a transparent superhydrophobic self-cleaning coating and a radiative heat dissipation and cooling coating, reduces the surface temperature of the photovoltaic panel. Thus, by integrating a double-layer heat sink and a high-efficiency heat dissipation mechanism, this device achieves efficient heat dissipation of the solar panel backsheet.

[0016] 2. This utility model incorporates a protective component, which includes a polymer composite frame, a carbon fiber reinforcement layer, a lightweight woven mesh reinforcement, and a nano-composite coating. In use, the polymer composite frame reinforces and protects the backsheet. The lightweight polymer composite frame reduces weight while maintaining structural strength. The high stiffness of the carbon fiber reinforcement layer further strengthens the polymer composite frame. The lightweight woven mesh reinforcement further enhances the hardness of the polymer composite frame, improving its overall compressive strength. The nano-composite coating forms a dense waterproof barrier, improving the corrosion resistance of the polymer composite frame. Therefore, this device enhances the protection of the solar panel backsheet itself, making it less susceptible to damage. Attached Figure Description
