Description
The present invention relates to a solar concentrator, and more particularly, to a solar concentrator that can be used in various forms such as a cooker type, a boiler, and a generator by collecting solar light in a convex lens manner.
Generally, as a method of using solar energy, there is a method of absorbing solar heat by using solar power generation, solar heat collecting tube or heat collecting plate to produce electricity using solar cell, and collecting the solar heat, which is used for hot water production or heating, Or sunlight natural light that is sunlighted using solar natural light module or reflector for photocatalytic use.
As is well known, in order to utilize the maximum amount of solar energy, it is necessary to efficiently concentrate the sunlight. Various solar concentrators are used for this purpose. The optical density of the concentrator is used by solar power generation, solar heat collection, Whatever the method, it is directly linked to solar energy efficiency.
The solar concentrator may be a point-focus dish type, a point focus Fresnel lens type, a linear-focus Fresnel lens type, a heliostat type, a Gregorian / Cassegrain condenser, and a holographic prism sheet, and many other various methods are known, and an optical system using a condenser lens and a condenser mirror is used for condensing.
In recent years, studies on the utilization of natural energy have been actively conducted due to exhaustion of fossil fuels and environmental pollution, and research and utilization of solar energy, wind power, wave power, and geothermal energy, which are known as infinite energy sources, are becoming active.
In the case of solar heat, a technique using a double vacuum tube is widely used in order to minimize heat loss and increase heat efficiency.
Conventionally, a double vacuum tube for collecting solar heat is composed of an inner tube for heat exchange of heat medium and an outer tube spaced from the inner tube, and a vacuum is formed between the inner tube and the outer tube.
Korean Patent Laid-Open Nos. 10-2011-0066303, 10-2010-0067519, and 10-2008-0031308 disclose various solar heat collectors using a vacuum tube.
However, conventional solar heat collectors have a limitation in maximizing the heat collecting efficiency in terms of structure.
However, in the conventional solar collector as described above, a light collecting plate for collecting sunlight is necessarily required, and the collecting tube is formed in a simple cylindrical shape, and there is a limit to collect heat according to the degree of condensing by the light collecting plate.
Therefore, there is a serious demand for an improved heat collecting tube which can increase the heating efficiency and freely change the use form by collecting and collecting solar light through the lens shape without using a separate light collecting plate.
SUMMARY OF THE INVENTION [0008] Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide a solar concentrator concentrating tube capable of collecting and collecting sunlight in various aspects through a lens- .
It is another object of the present invention to adjust the focal length by controlling the size of the lens according to the change of the diameter of the condensed heat collecting body.
In addition, another object of the present invention is to allow sunlight to pass through one lens and to divide and condense the light into one focal point or a plurality of focal points.
Another object of the present invention is to increase the versatility in use because the condensed heat collecting body can be variously applied for cooking, boiler, and generator.
Another object of the present invention is to minimize the heat loss by discharging only the pressure when the condensing heat collecting body is used for cooking, thereby enabling the cooking by the pressure cooking method.
Another object of the present invention is to provide a condensing heat collecting body for a boiler and a generator, so that the condensing heat collecting body can be installed outside a home, office, or other building.
In order to achieve the above-mentioned object, in order to avoid the use of a light collecting member or a light collecting member collecting solar light at one point, a plurality of convex lenses are formed on the outer surface and inner surface of the light collecting body, And a plurality of focal points are formed between the collecting holes of the collecting and collecting body so as to heat the collecting collecting collector tubes,
A first lens portion having a convex lens shape at an equal interval on the outer surface along a center line that forms the thickness of the light collecting and collecting body, and a convex lens shape obtained by dividing the entire size of the first lens portion into three equal parts on the inner surface of the light- The first lens unit and the third lens unit are formed integrally with each other with reference to the light collecting body. When sunlight is condensed through the first lens unit and incident, the light passes through the second lens unit A plurality of focal points formed at three points and configured to disperse sunlight;
A cooking tool having a handle is formed at one end of a cooking body inserted into a heat collecting space of the condensed heat collecting body and containing a food to be cooked and a porous mineral thin film coating layer is formed on the surface of the cooking body, And is configured to be used in the form of a non-sagging cooking utensil.
As described above, the present invention has an effect of collecting and collecting sunlight in various aspects through the function of a lens system without a separate light collecting plate.
Further, the focal distance can be adjusted by adjusting the size of the lens according to the diameter change of the condensed heat collecting body, and the heating volume can be easily changed.
In addition, solar light passes through a single lens and can be divided into a single focal point or a plurality of focal points, thereby increasing the efficiency per unit heating area.
In addition, since the condensing heat collecting body can be variously applied for cooking, boiler, and generator, versatility in use is expanded, and the application is easily changed.
In addition, when the condensing heat collecting body is used for cooking, the cap is closed to minimize the heat loss by exhausting only the pressure, and it is possible to cook by the pressure cooking method, thereby shortening the cooking time and maintaining the unique flavor of the food material.
In addition, since the condensing heat collecting body can be installed exclusively for a boiler and a generator, it can be installed outside a home, office, or other building, so that installation cost is low and heating cost is reduced.
