Active solar tracking heat collecting device and air cylinder structure thereof

Abstract

The invention provides an active solar tracking heat collecting device and an air cylinder structure thereof. The device comprises a water tank and a photo-thermal conversion element, wherein the upper end of the water tank is of an opening structure, the photo-thermal conversion element floats on the upper portion of the water tank, the photo-thermal conversion element comprises a base body formed by a foaming material, a groove with an opening in the upper side is formed in the base body, a heat collecting tube box comprises a first tube opening and a second tube opening, the first tube opening is connected with an inlet of a left heat release tube set, the second tube opening is connected with an inlet of a right heat release tube set, an outlet of the left heat release tube set is connected with an upper tube, and an outlet of the right heat release tube set is connected with the upper tube; and the first tube opening and the second tube opening are formed in one side of the heat collecting tube box. According to the active solar tracking heat collecting device and the air cylinder structure thereof, a large amount of steam is generated without the assistance of a heating device, the floating foam material supports a photo-thermal conversion layer out of the water surface, dissipation of generated heat energy from a film to a lower-layer liquid is restrained, therefore thevaporization efficiency of the device is improved, and the great potential of the device as a photo-thermal conversion new energy material is shown.

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.
