Abstract

The invention provides a solar thermal collector system. The solar thermal collector system comprises a solar thermal collector and a heat utilization device. The solar thermal collector comprises thermal collection pipes used for absorbing heat of solar energy so as to heat water inside the solar thermal collector. The thermal collection pipes are metal thermal collection pipes. Each thermal collection pipe comprises a metal base pipe, wherein the outer surface of the metal base pipe is covered with an anticorrosive coating and a heat absorption coating in sequence. According to the solar thermal collector system, the heat absorption coating with high absorptivity is arranged, so that solar heat absorption capacity is improved.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector with an absorption film. 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. Solar energy is an inexhaustible clean energy with a huge amount of resources. The total amount of solar radiation energy received by the e...
