Abstract

The invention provides a solar heat utilization system. The solar heat utilization system comprises a solar water heater and a heat utilization device, wherein the solar water heater comprises a heat collector; the heat collector is used for absorbing heat of the solar energy to heat the water in the solar water heater and is a metal heat collector pipe; the metal heat collector pipe comprises a metal base tube; the outer surface of the metal base tube is sequentially coated with an anticorrosive layer and a heat absorbing layer. The invention provides the base tube with a high heat-absorbing rate to increase the solar heat absorbing capability.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat utilization 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. 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 surface ...
