Operation method of loop heat pipe solar heat collection device

Abstract

The invention provides an operation method of a loop heat pipe solar heat collection device. The heat collection device comprises a reflecting mirror and a heat collection pipe box, a heat collectiondevice comprises a descaling stage, and the following operation modes are adopted: in the descaling stage, the following operation modes are adopted: heat collection is performed on the heat collection pipe box at the front period time within one period time P, and at the later period time within the period, the heat collection pipe box is not subjected to heat collection. Heat collection or non-heat-collection is periodically performed on the heat collection pipe box, fluid can be frequently evaporated, expanded and contracted in an elastic pipe bundle, and therefore, the elastic pipe bundleis continuously driven to vibrate, descaling operation can be further achieved, and the heat exchange effect is improved.

Description

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

Problems solved by technology

[0006] In view of the above problems, the present invention improves on the basis of the previous invention, and provides a new loop heat pipe solar heat collection system, thereby solving the problem of low heat transfer and uneven heat transfer of heat pipes

[0007] In the application, it is found that the continuous heating of solar heat collection or no heating at night will lead to the formation of stability of the internal fluid, that is, the fluid is not flowing or has little fluidity, or the flow is stable, resulting in a greatly weakened vibration performance of the heat exchange collector tube, thus affecting the heat collector tube.
