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

Embodiment 1

[0106] As an improvement, the central controller 7 automatically controls the opening and closing of the valves 13, 15 according to the detected indoor temperature and the temperature of the water entering the radiator.

[0107] Preferably, valve 15 is open and valve 13 is closed during normal operation.

[0108] If the indoor temperature is higher than the water temperature entering the radiator, the central controller 7 automatically controls the valve 15 to close, and the valve 13 is opened simultaneously. Ensure that water does not enter the radiator, because if water enters the radiator 4 at this time, not only does not play the effect of heat dissipation, but the heat in the room is transferred to the water, thereby reducing the heat dissipation effect. Energy can thus be saved by this measure.

[0109] If the water temperature detected by the bypass pipeline temperature sensor 12 is higher than the indoor temperature, the central controller automatically controls the v...

Embodiment 2

[0116] As an improvement, the central controller 7 automatically controls the closing of the valves 11, 13, 15 according to the detected temperature of the inlet pipe of the radiator 4, the temperature of the water in the collector pipe and the temperature of the bypass pipe.

[0117] If the temperature of the radiator inlet pipe detected by the central controller 7 is lower than the indoor temperature of the radiator, the central controller 7 automatically closes the valve 15 and the valve 11, and opens the valve 13. The water in the heat collecting tube 2 continues to be heated by solar energy. When the water temperature in the heat collecting tube exceeds a certain value of the indoor temperature, preferably more than 10 degrees Celsius, the valves 11 and 15 are opened, and the valve 13 is closed, so that the water enters the radiator to dissipate heat.

[0118] Through the above measures, the heat dissipation of the radiator can be intelligently controlled.

[0119] Prefer...

Embodiment 3

[0128] Embodiment 3 is a further improvement of Embodiment 2.

[0129] If the temperature of the radiator inlet pipe detected by the central controller 7 is lower than the indoor temperature of the radiator, the central controller 7 automatically closes the valve 15 and the valve 11, and opens the valve 13. The water in the heat collecting pipe 2 continues to be heated by solar energy. When the water temperature in the heat collecting pipe 2 exceeds a certain value of the indoor temperature, preferably more than 10 degrees Celsius, the valve 11 is opened, and the water flows through the bypass pipe. If the bypass pipe sensor 12 When the detected water temperature exceeds a certain degree in the room, such as 5 degrees Celsius, the bypass pipeline valve 13 is closed, and the radiator pipeline valve 15 is opened, so that water enters the radiator to dissipate heat.

[0130] Through the above measures, the temperature of the water is detected through the bypass pipeline, which fu...

The central controller automatically controls opening and closing of the first valve and the second valve according to the detected indoor temperature and the temperature of the water entering the radiator. The intelligent control solar thermal collecting pipe is provided by the invention, and intelligent detection and control of a solar cooling system are achieved.

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...
