Regular hexagonal solar thermal-collecting tube fabrication and use method

Abstract

The invention relates to a regular hexagon solar heat collecting tube and an application method, belonging to the solar energy application field. The heat collecting tube is made by plastic particles under certain process conditions, and has a regular hexagon appearance with plane outer lateral surfaces and concave inner lateral surfaces as well as certain shock-resistance physical index. The heat collecting tube has the advantages of high heat collecting efficiency, little heat reflection, long service life and aging resistance, and meets outdoor application conditions. Copper heat pipes are installed in the heat collecting tubes with different thicknesses and widths; the heat collecting tubes are sealed and vacuumized or keep constant pressure; sunlight converges on the concave parts of the inner sides of the tubes and then directly gathers on the copper heat pipes; water does not go through the regular hexagon solar heat collecting tube; heat is transferred through heat pipes to heat a water collecting system; all pipes can be combined horizontally or randomly combined on the six surfaces; and the heat collecting tubes are welded for fixation by a plastic welder or shaped in anchor ear connection. The heat collecting tubes are connected to a heat exchange and water collection system and a water storage system to form a solar collector, and can be integrally installed on a wall, a roof and a balcony, and outside or inside a window.

Problems solved by technology

In recent years, the application of glass vacuum tubes as heat collectors has been developed and is rapidly becoming the main component of solar collectors. However, due to the limitation of the material of the glass tube itself, the glass vacuum tube itself has poor mechanical shock resistance, and the glass tube is easy to explode and break. The problem is that due to the characteristics of the installation location of the solar collector, once the glass breaks, falls, or leaks, it is difficult to avoid safety issues; at the same time, the glass tube collector has a loose structure and occupies a large area. It has strict installation angle and installation location requirements. It is difficult to coordinate with the building space, which makes people's use of solar energy, a clean energy, be curbed. The market is in great need of a new type of solar heat collection technology that can adapt to the ever-changing technology, retain heat to the greatest extent, improve thermal efficiency, and resist mechanical shock. Strong performance, not easy to break, safe and reliable installation, compact structure, small footprint, easy to realize modular combination installation, and can be integrated on walls, roofs, balconies, windows, and the production and application of solar heat collectors.
