Embodiment Construction

[0029] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] figure 1 A solar heat collector is shown, the heat collector includes a heat collecting tube 2, a reflector 1 and a heat collecting plate 3, and two adjacent heat collecting tubes 2 are connected through the heat collecting plate 3, so that multiple collectors A tube sheet structure is formed between the heat pipe 2 and the adjacent heat collecting plate 3; the solar heat collector system includes two tube sheet structures, and a certain angle is formed between the two tube sheet structures, and the included angle The direction is opposite to the bending direction of the arc structure of the reflector, and the focal point D of the reflector 1 is located between the angles formed by the tube-sheet structure.

[0031] As an improvement, the cross-section of the heat collecting tube 2 is rectangular, and the heat collecting plate 3 co...

Abstract

The invention provides a solar thermal collector which comprises two tube plate structures, wherein a certain included angle is formed between the two tube plate structures; the direction of the included angle is opposite to a bending direction of an arch-shaped structure of a reflecting mirror; the focus of the reflecting mirror is positioned between the included angle formed by the tube plate structures; thermal collection tubes are internally provided inner fins; the inner fins are connected with rectangular inner corners; the thermal collection tubes are internally divided into a plurality of small channels by the inner fins; communication holes are formed in the inner fins; the thermal collection tubes and the thermal collection plates are made of a copper aluminum alloy. As a novel copper aluminum alloy is researched and developed and applied to the thermal collection tubes, the function of thermal collection can be improved, and meanwhile the high-temperature resistance of the thermal collector can be greatly improved.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector. 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. . Solar thermal conversion is a solar energy utilization method with high energy conversion efficiency and utilization rate and low cost, which can be widely promoted in the whole society. In solar heat utilization devices, the key is to convert solar radiation energy into heat energy, and the device that realizes this conversion is called a solar collector. Howeve...
