Description

The present invention relates to a solar water heating system,

The present invention relates to a solar hot water system, and more particularly, to a solar hot water system capable of enhancing energy efficiency by constituting a parabolic structure collecting part and a solar trajectory tracking system.

At present, human beings on the planet face two problems that must be resolved. The first is the depletion of fossil energy such as petroleum coal used by humankind. The second is the implementation of the climate change convention to prevent global warming caused by the increased use of fossil energy. The fossil energy that mankind could use forever is said to be depleted if it continues to be used in the same amount as now, 40 years for oil, 210 years for coal, 65 years for natural gas, and 50 years for uranium. Clean alternative energy called 'Future Energy' or 'Green Energy' attracts attention in solving these difficult problems, and each country is investing heavily in the development and dissemination of alternative energy.

Alternative energy can be sunlight, solar heat, biomass, wind control, geothermal, fuel cell, hydrogen energy, waste energy, etc. In the present invention, however, it is intended to focus on using solar and solar heat.

The sun has a surface temperature of 6,000 ° C and a central temperature of about 15 million ° C, resulting in a tremendous amount of heat and light, reaching a total of 9.2 × 1022 kcal, but the Earth is about 150 million km away from the sun Therefore, the amount of solar radiation reaching the Earth (solar constant) is only about 2 cal.

In addition to being a source of energy for our daily life, this solar radiation energy is also the driving force of various weather phenomena and currents in the sea. In addition, solar energy uses solar cells, solar water heater, , The sun, and solar generators.

As such, the most important factor for improving efficiency in a system using solar heat such as solar water heater, solar house, solar furnace, and solar generator is that the solar heat should be able to be taken for a long time, do.

That is, since the sun moves along the orbit during the time from sunrise to sunset, if the apparatus using the solar heat is fixed, the solar heat can not be received under the optimal condition, and the efficiency of the system is lowered .

Therefore, it is well known in the academic world that solar heat can be taken in optimal conditions for a long time if the solar heat receiving apparatus is traced along the moving orbit of the sun to increase the efficiency of the system by 30 to 60% A solar tracking system was proposed.

In addition, the structure is extremely complicated, and there is a problem that the precision of the structure is poor and the effect of the chip is deteriorated, so that it is not practically used.

In addition, as a conventional high performance solar collector tube, a vacuum tube type is spreading. Despite its high performance, it is a glass tube, which is fragile and expensive. And, when installed, the amount of water injected into the tube is high, so that the load is applied to the entire system, and a robust structural frame is required to maintain the system.

FIG. 1 is a view showing a solar heat collecting structure of a solar hot water system according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating a solar heat tracing structure of a solar hot water system according to an embodiment of the present invention.

As shown in FIG. 1, a collecting unit 100, which is arranged in parallel in a parabolic shape according to an embodiment of the present invention and has an inner surface formed of a reflecting mirror to collect solar heat; A tube pipe 200 extending in the longitudinal direction of the upper surface of the heat collecting part 100; A water storage portion connected to the vacuum pipe 200 and heated by the vacuum pipe 200; A motor part 400 connected to the lower part of the heat collecting part 100 to tilt or rotate the heat collecting part 100; And a drive control unit 500 connected to the motor unit 400 and controlling the drive to face the heat collecting unit 100 according to the locus of the sun.

Second, the solar hot water system according to the embodiment of the present invention constitutes a solar automatic tracking system in order to collect solar energy efficiently. By providing a motor and a swivel for moving the collecting part 100 formed of a plurality of parabolic tubes as a whole and a auxiliary wheel for supporting the swivel, the entire system can smoothly move even at a very small power, The microcontroller is installed to automatically track the sun moving along the trajectory during the daytime, thereby maximizing or optimizing the light-receiving cross-section of the sunlight, thereby enhancing energy collection efficiency.

As shown in FIG. 1, the heat collecting structure of the solar hot water system according to the embodiment of the present invention includes: a collecting part 100 arranged in parallel in a parabola shape and having an inner side formed of a reflecting mirror to collect solar heat; And a vacuum pipe 200 extending in the longitudinal direction of the upper surface of the heat collecting part 100.
