Example Embodiment

[0042]Detailed description of the specific embodiments of the present invention will be described in conjunction with the accompanying drawings.

[0043]In this discipline, if there is no special instruction, "×", "*" means multiplication, " / " indicates division, "×", "*" means multiplication.

[0044]Such asfigure 1 As shown, a heat collecting device includes a collecting tube box 8, a left upper tube 21, a right upper tube 22, and an exothermic tube set 1 including a left discharge heat pipe group 11 and a right amphippoint 12, a left heat pipe. The group 11 is in communication with the left upper tube 21 and the collecting tube box 8, and the right-discharge tube set 12 is in communication with the right upper tube 22 and the collecting tube box 8, thereby causing the collector tube 8, the left upper tube 21, the right upper tube 22 and the exothermic tube set 1. The heating fluid is formed, and the phase-converted fluid is filled in the collector tube box 8, each of which includes a c...

Abstract

The invention provides an accumulative temperature difference controlled loop heat pipe solar system, which is characterized in that n liquid level sensing elements are arranged, the difference Di = Li-Qi-1 between the liquid level Li in the current time period and the liquid level Qi-1 in the previous time period is sequentially calculated, and the n liquid level differences Di are subjected to arithmetic accumulative summation; and when the value of Y is lower than a set threshold value, a controller controls a heat collection pipe box to stop heat collection or continue heat collection; if Y is greater than 0 and lower than the threshold value, the controller controls the heat collection pipe box to stop heat collection; and if Y is smaller than 0 and smaller than the threshold value, the controller controls the heat collection pipe box to stop heat collection. The stable state of the fluid is judged according to accumulation of liquid level difference changes, so that the results are more accurate, and the problem of error increase caused by aging due to the running time problem is solved.

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...
