Solar heat collector detecting leakage through humidity measuring device

Abstract

The invention provides a solar flat plate type heat collector which comprises a box body and heat collecting pipes. A transparent cover plate is arranged on the top of the box body; a heat preservation layer is arranged at the bottom of the box body; and the heat collecting pipes are arranged in the box body. The solar flat plate type heat collector further comprises a humidity measuring device arranged in the box body and in data connection with a control system; and once liquid leaks, the liquid enters the box body, when the detected humidity is higher than a certain value, measurement data are abnormal, and the control system closes valves of liquid entering into the heat collecting pipes in time. The novel solar heat collector for automatically detecting leakage detects leakage by detecting the humidity of the heat collecting pipes.

Description

[0001] Application number: CN2016102078404 [0002] Application date: 2016.4.5 [0003] Invention Title: Leak-Detecting Solar Thermal Collector technical field [0004] The invention belongs to the field of solar energy, in particular to a flat-plate solar heat collector. Background technique [0005] 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. . Solar thermal conversion is a solar energy utilization method with high energy conversion efficiency and utilization rate and low cost, which can be widely promoted in the whole society. In solar heat utiliz...

Problems solved by technology

[0006] In solar collectors, the flat plate structure is a very common form. This structure generally includes multiple heat collecting tubes arranged in parallel. However, in operation, the fluid distribution in different heat collecting tubes often occurs unevenly. There is also the fact that the temperature of the fluid in different heat collecting tubes is different due to uneven heating, resulting in different pressures in different heat collecting tubes

Long-term operation in this case will cause damage to the heat collecting tube with high pressure, resulting in fluid leakage, but there is currently no better heat collector for leak detection
