Embodiment Construction

[0021] 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.

[0022] The polymer heat collecting tube 1 of the present invention is the main component, and is formed by extrusion after adding heat transfer agent, endothermic agent and compatibilizer with polymer resin. The polymer resin is made of PE-RT pipe special material, 100 parts, the heat transfer agent is 10 parts of flake graphite, the heat absorbing agent is 10 parts of carbon black, and the compatibilizer is 5 parts of PE grafted maleic anhydride. The resin matrix, heat transfer agent,...

Abstract

The invention provides a heat-collecting tube applied to a polymer-base solar heat collector. The heat-collecting tube is prepared by adding a heat absorbent, a heat-conducting agent and a compatibilizer into a polymeric matrix. The heat-collecting tube has the advantages of more obvious heat-collecting effect, longer service life and better heat-collecting efficiency and heat-preserving effect. The heat-collecting tube prepared from the polymeric matrix, the heat absorbent, the heat-conducting agent and the solubilizing agent guarantees better light resistance and aging resistance of the heat collector and better heat-collecting effect.

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...
