Solar heat collector

Abstract

The invention provides a solar heat collector. The solar heat collector further comprises heat collection tubes, transparent glass plates, heat isolation layers and heat absorption films, wherein each heat collection tube comprises a heat absorption part and a heat release part; each heat absorption part absorbs solar energy radiation; one heat absorption film is arranged on the front surface of the heat absorption part of each heat collection tube; one transparent glass plate covers the front surface of the heat absorption part of each heat tube; and one heat isolation layer is reserved between each heat absorption part and the corresponding transparent glass plate. According to the solar heat collector provided by the invention, through arranging the heat absorption films and the heat isolation layers, solar energy absorption is reinforced, heat absorption effect is ensured, and energy is saved.

Description

Technical field [0001] The invention belongs to the field of solar energy, and particularly relates to a solar heat collector. Background technique [0002] With the rapid development of modern society and economy, human demand for energy is increasing. However, traditional energy reserves 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 has become more and more serious, which greatly restricts the development of society and the improvement of human life quality . The energy issue has become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially pollution-free clean energy sources, has become a hotspot of research. [0003] Solar energy is an inexhaustible and inexhaustible clean energy, and the resource is huge. The total amount of solar radiation energy collected on the earth'...

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
