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. Descaling and heating efficiency

Embodiment Construction

[0043] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] In this article, if there are no special instructions, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0045] like figure 1As shown, a heat collection device includes a heat collection tube box 8, a left upper tube 21, a right upper tube 22 and a heat release tube group 1, the heat release tube group 1 includes a left heat release tube group 11 and a right heat release tube group 12, and the left heat release tube group 12. The group 11 is communicated with the left upper tube 21 and the heat collecting tube box 8, and the right heat releasing tube group 12 is communicated with the right upper tube 22 and the heat collecting tube box 8, so that the heat collecting tube box 8, the left upper tube 21, the right upper tube 22 and the heat releasing tube group 1 are connected. A closed cycle of heati...

Abstract

The present invention provides a loop heat pipe solar heat collection device through a focus change, the heat collection device includes a reflector and a heat collection tube box, and in the descaling stage, the heat collection tube box is located at the focus of the reflector to complete the process. For example, the collector tube box is used to collect heat or not to collect heat. When heat collection is required, the heat collector box is located at the focus of the reflector. When heat collection is not required, the heat collector box is not located at the focus of the reflector. According to whether the heat collecting tube box is located at the focus of the reflector, the present invention can make the fluid evaporate, expand and contract frequently in the elastic tube bundle, thereby continuously driving the vibration of the elastic tube bundle, thereby further realizing the descaling operation and improving the heat exchange effect.

Description

technical field [0001] The invention belongs to the field of solar energy, and in particular relates to a solar heat collector system. Background technique [0002] With the rapid development of modern society and economy, human beings have an increasing demand for energy. However, the reserves of traditional energy sources such as coal, oil, and natural gas are constantly decreasing and becoming 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, which greatly limits the development of society and the improvement of human life quality. . The energy problem has become one of the most prominent problems in the contemporary world. Therefore, the search for new energy, especially non-polluting clean energy has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy, and the amount of resources is huge. The total amount of solar radi...
