An active solar tracking heat collector and its cylinder structure

Abstract

The invention provides an active solar tracking heat collection device and its cylinder structure. The device includes a water tank and a light-to-heat conversion element. The upper end of the water tank is an open structure, and the light-to-heat conversion element floats on the upper part of the water tank. The light-to-heat conversion element includes a base formed of foaming material, and a groove with an upper side opening is formed on the base. The heat collecting tube box includes a first nozzle and a second nozzle. The first nozzle is connected to the inlet of the left heat release tube group, and the second The nozzle is connected to the inlet of the right heat releasing tube group, the outlet of the left heat releasing tube group is connected to the upper tube, and the outlet of the right heat releasing tube group is connected to the upper tube; the first nozzle and the second nozzle are arranged on one side of the heat collecting tube box. The invention generates a large amount of steam without the assistance of a heating device, and the floating foam material lifts the light-to-heat conversion layer out of the water surface, inhibiting the dissipation of the generated heat energy from the film to the liquid in the lower layer, thereby improving the vaporization efficiency of the device, and showing its advantages It has great potential as a new energy material for photothermal conversion.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector system. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The total amount of solar radiation energy received by the earth's s...

Problems solved by technology

[0007] There are more than 10,000 islands in China, but most of them are uninhabitable due to lack of fresh water, and there are less than 500 permanent residents, which restricts the functions of island development and national defense.
