Embodiment Construction
[0019] The structure when the present invention is applied to solar heat collectors is as attached figure 1 As shown, it is a polymer-based solar heat collector, which consists of three parts: a polymer heat collecting tube 1, a polymer glass cover plate 2, and a polymer thermal insulation reflective plate 3. Among them, the polymer glass 2 is polycarbonate glass with a thickness of 1mm, and the light transmittance reaches 85%. Using extrusion molding process. The area size is 800mm×1200mm.
[0020] The polymer heat collecting tube 1 of the present invention is the main component, and is formed by extruding polymer resin with added heat conducting agent and compatibilizer, and then coated with coating film. 100 parts of PE-RT pipe special material is used as polymer resin, 10 parts of flake graphite is used as thermal conductive agent, and 5 parts of PE grafted maleic anhydride is used as solubilizer. The resin matrix, heat conducting agent and solubilizing agent are stirre...
