A solar collector tube

Abstract

The invention provides a solar heat collection tube. The heat collection tube comprises a heat absorption part and a heat release part, wherein the heat absorption part absorbs solar energy, and heat is transferred to water in a water tank through the heat release part. The heat collection tube is characterized in that transversal fins are arranged outside the heat release part. According to the solar heat collection tube provided by the invention, through arranging the transversal fins outside the heat release part, heat release effect is further reinforced, and energy is saved.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collecting tube. 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 su...

Problems solved by technology

However, the water circulation system of the solar thermal collection system is a closed system. The circulating water is circulated and heated, but some non-condensable gases will be produced during the circulating water circulation. In addition, sometimes the water in the collector will form when the sun is strong. Soda-water mixture, so in the case of heated water for heat exchange, the heat transfer coefficient is reduced due to the presence of non-condensable gas or the formation of steam-water hot water, so that solar energy cannot be fully utilized

[0005] In view of the above problems, the present invention provides a new solar water heater, thereby solving the problem of low heat transfer coefficient in the case of heat exchange between solar hot water and its fluid
