Intelligent control of solar collector system according to bypass pipe temperature

Abstract

The invention provides a solar energy heat collector system which comprises a reflector and a heat collecting pipe. A first valve and a first temperature sensor are arranged on a heat dissipater pipeline for separately controlling the flow of water entering a heat dissipater and detecting the temperature of water entering the heat dissipater. The solar energy heat collecting system is also provided with a by-pass pipeline connected to the heat dissipater pipeline in parallel, and a second valve and a second temperature sensor are arranged on the by-pass pipeline for separately controlling theflow of water on the by-pass pipeline and detecting the temperature of water. The heat dissipater is arranged indoors and a third temperature sensor is arranged indoors for detecting the indoor temperature. A central controller controls opening and closing of the first, second and third valves automatically according to the detected temperature of an inlet pipe of the heat dissipater, the detectedtemperature of water of a heat collector pipe and the detected temperature of the by-pass pipeline. The invention provides the intelligently controlled solar energy heat collecting pipe which detectsand controls a solar energy heat dissipating system intelligently.

Description

technical field [0001] The invention relates to a heat collecting tube technology, in particular to a heat collecting tube of a heat pipe with a new structure. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of h...

Problems solved by technology

Current heat collecting tubes are also widely used in the treatment of various diseases, especially in the treatment of chronic diseases caused by aging and old damage to muscles and ligaments, such as CN2167709Y patent, but in the current prior art, such as CN2167709Y patent , because the steam generated directly by heating will cause the temperature of the generated steam to be too high, and it will cause too much moisture in the generated steam, and the drug may be deposited in the lower part because it is a particle, so the active ingredient in the ejected steam The content is too low, and the temperature is too high, and the degree of intelligence in the existing technology is not high, and effective intelligent operation cannot be carried out

[0005] In the background technology, when using solar energy to heat the heat collecting tube, the solar energy either directly heats the heat collecting tube, or generates steam through secondary heat exchange, especially directly heats the heat collecting tube, and uses the convective heat exchange inside the heat collecting tube to carry out the heating of the upper and lower parts of the heat collecting tube. Fluid convection heat exchange, but in this case, the hot fluid in the lower part needs to be naturally convected to the upper part, and the heat transfer efficiency is low

[0006] At present, the degree of automation of solar heat collectors is not high. Although the prior art has also studied the intelligent control of solar energy, there are not many researches on the intelligent control of heat collectors. In view of the above problems, the present invention provides a new intelligent Controlled solar collector system, thus intelligent control of solar energy utilization process
