Loop heat pipe solar heat collection device with variable focus position

Abstract

The invention provides a loop heat pipe solar heat collection device with a variable focus. The heat collection device comprises a reflector and a heat collection pipe box, wherein at a descaling stage, whether the heat collection pipe box is located at the focus of the reflector or not is judged to complete heat collection or non-heat-collection operation on the heat collection pipe box, and theheat collection pipe box is located at the focus of the reflector in need of heat collection and is not located at the focus of the reflector without the need for heat collection. By judging whether the heat collection pipe box is located at the focus of the reflector or not, fluid can be frequently evaporated, expanded and contracted in an elastic pipe bundle, so that the elastic pipe bundle is continuously driven to vibrate, the descaling operation can be further realized, 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.
