Abstract

The invention provides a solar water heater. The solar water heater comprises a heat collector, the heat collector is used for absorbing heat of solar energy to heat water in the solar water heater and is a glass evacuated collector tube, the glass evacuated collector tube comprises a glass base tube, and a heat absorption layer covers the outer surface of the glass base tube. The heat absorption capacity of the heat collector provided with the heat absorption coating with high absorptivity is improved.

Description

technical field [0001] The invention belongs to the field of solar energy, and in particular relates to a solar water heater with an absorption film and a system thereof. Background technique [0002] With the rapid development of modern society and economy, human beings have an increasing demand for energy. However, the reserves of traditional energy sources such as coal, oil, and natural gas are constantly decreasing and becoming 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, which greatly limits the development of society and the improvement of human life quality. . The energy problem has become one of the most prominent problems in the contemporary world. Therefore, the search for new energy, especially non-polluting clean energy has become a research hotspot. Solar energy is an inexhaustible and inexhaustible clean energy, and its resources are ...
