Abstract

The invention provides a loop heat pipe solar heat collection temperature control method. A heat collection device comprises a reflector and a heat collection pipe box. The heat collection device comprises a descaling stage, and the following operation modes are adopted: in the descaling stage, a temperature sensing element is arranged in the heat collection device and is used for detecting the temperature in the heat collection device, the temperature sensing element is in data connection with a controller, and the controller controls whether to collect heat of the heat collection pipe box or not according to the detected temperature. The heat collection pipe box is subjected to heat collection or not subjected to heat collection through temperature detection, fluid can be frequently evaporated, expanded and contracted in an elastic pipe bundle, and therefore the elastic pipe bundle is 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...
