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...

Abstract

The invention relates to a collecting tube of a polymer-based solar collector, which is prepared and formed by adding thermal conducting agent and solubilizer to a polymer matrix, and then is plated with a light selectivity film. The collecting tube has more significant heat collection effect and longer service life so that the solar collector has better heat collection efficiency and heat insulation effect. An optimized collecting tube formula ensures better light and oxygen aging resistance and better heat collection effect of the collector.

Description

technical field [0001] The patent of the invention belongs to the technical field of solar heat utilization, and in particular relates to a heat collecting tube of a polymer-based solar heat collector. Background technique [0002] Energy and the environment are two major themes that the world is concerned about today. When non-renewable energy sources such as electricity, coal, and oil are running out frequently, and energy issues have increasingly become a bottleneck restricting the development of the international society and economy, more and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new impetus for economic development. Solar energy is the most fundamental energy source on the earth, and the total amount of solar energy received by the earth every year is 1×10 18 kW·h, equivalent to 5×10 14 A barrel of crude oil is more than 10,000 times the world's annual energy consumption. Solar energy utilization include...
