Problems solved by technology

[0004] When the solar energy is used to heat the air device, the solar energy either directly heats the air, or generates hot air through secondary heat exchange, but in this case, the thermal fluid in the lower part needs to be naturally convected to the upper part, and the heat transfer efficiency is low
Aiming at the structure of the solar air heating device, a lot of research and development and improvement have been carried out in the existing technology, but overall the heat collection capacity is insufficient, and there is also the problem of easy fouling due to long running time, which affects the heat collection effect

Abstract

The invention provides a solar air heating device. The solar air heating device comprises an air pipeline and a heat collecting device, the heat collection device comprises a heat collection component and a heat release component, the heat release component is arranged in the air pipeline, the heat collection component is arranged outside a box body, the heat collection component absorbs solar energy, heat is released into the air pipeline through the heat release component, and the heat collection component is used for heating the air passing through the air pipeline. According to the solar air heating device with a novel heat pipe structure, the heat collection component and the heat release component are arranged, so that the heat transfer speed is high, the heat transfer speed of solar energy is increased, and the heat absorption capacity can be further met.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar air heating device. 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 surf...
