The present invention relates to a solar energy collecting plate, and in order to effectively collect heat, a transparent material having good solar permeability is attached to the front of the double film, and the heat collected at the rear of the double film prevents heat loss caused by external temperature. Insulating material is attached to the film, and when the sunlight passes through the transparent material and touches the outer surface of the double film, the outer surface of the double film with black coating is thermally degraded by the sunlight, and the thermally deteriorated solar heat is applied to the water flowing between the double films. The present invention relates to a solar energy collector that can be absorbed by direct heat to maximize the heat collection effect.
More specifically, the double formed film is divided into 50mm in width and partitioned, and the distance between the two films is formed within 0.1 ~ 0.5mm, regardless of the installation method and structure. It is a dimension obtained by self experiments that can effectively form a water film layer in a channel when water flows.
In addition, the material of the double film can be made of iron plate when the heat collecting plate structure is a flat plate. However, even if it is slightly deformed by heat during operation, it is impossible to control the amount of water supplied and thus no water film phenomenon can be obtained.
Because the steel plate is not elastic, if the water supply is not accurate, space is generated in the waterway, so the water flows into the solar treatment due to the weight of the water, so that the water film phenomenon is not obtained and there is no heat collection effect.
In this case, when the material of the double film is made of synthetic resin, the outer surface of the double film that receives sunlight is coated with a solar layer and a heat absorption coating agent is applied to the inner surface of the double film with a heat reflection layer so that heat does not go out. Thus, a solar energy heat collecting plate that can increase the heat collecting effect as desired by inexpensively manufacturing a film of a suitable material according to the use of a two-layer or three-layer structure (the domestic synthetic film production technology can produce a five-layer structure in one layer). It is about.
Conventionally, the solar heat collecting plate which is commonly used is focused on installing small pipes of a plurality of metallic materials.
However, although the metal small pipe is relatively higher in thermal conductivity than other materials, nevertheless, a method of increasing the thermal conductivity more than that of a general metal has not been utilized.
In addition, the conventional solar energy collecting plate was a facility type plate connecting method for manufacturing by combining a piece of copper plate with one small pipe. However, in the case of the heat collecting plate manufactured in this way, the heat collecting efficiency was deteriorated because the solar heat collected at the edge of the copper plate was not transferred to the heat medium of the copper pipe and escaped to the outside.
Most of the heat collecting plate currently produced is manufactured in a prefabricated equipment type, and such a prefabricated heat collecting plate has a gap, so that a leak occurs over time, and the manufacturing cost increases due to a complicated manufacturing process even in manufacturing cost.
In addition, the conventional solar energy collector plate is difficult to be installed in the form of an arch or curved in a flat plate type has a lot of difficulties and problems in producing a product according to the building specifications.
Due to the above problems, the thermal efficiency of the conventional solar energy collecting plate is not good, and in winter when the solar radiation is absolutely insufficient, there is a risk of freezing due to the characteristics of the long pipe structure due to the low temperature of the heating water, and a separate heating device is required. There is this.

The present invention has been made to solve the problems of the conventional solar energy collecting plate as described above, a transparent material having good solar transmittance is attached to the front surface of the double film, the heat collected on the rear of the double film to the outside temperature. Insulation is attached to prevent heat loss caused by the sun. When the sunlight reaches the outer surface of the double film through the transparent material, the outer surface of the double film with black coating is thermally degraded by sunlight. The purpose of the present invention is to provide a solar heat collecting plate capable of maximizing the heat collecting effect by directly absorbing the water flowing between the double films.
This object can be achieved by the configuration of the present invention, will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a state in which the present invention is attached to a building, Figure 2 is a cross-sectional view of the present invention.
As shown in the drawing, the present invention is divided into a film formed in a double is divided into 50mm width, the gap between the two film is formed within 0.1 ~ 0.5mm hot water flows inside while forming a water film, A dual film 20 having a solar heat absorbing coating agent applied to the outer outer surface and a heat reflection coating agent applied to the inner outer surface of the film;
It comprises a transparent material 10 is fixed to the outer outer surface of the double film (10).
That is, a plurality of partitions are formed and fused with the same material and thickness so as to maintain a constant gap between the film and the film, and the gap between the partition and the partition is constant, and a black coating is applied to the outer outer surface of the film 21. The solar heat absorption coating agent 24 is applied, and the heat reflection coating agent 25 is applied to the inner outer surface of the film 22.
In addition, the space between the film and the film is formed within 0.1 ~ 0.5mm, and the space between the partition and the partition within 50mm is that the narrower the space between the partition and the space is less water flows to form a thin water film well This is because the thinner the water film, the easier it is to be warmed up even with less solar heat. A protective film is formed by using the transparent material 10 at a predetermined interval on the outer outer surface of the double film 20.
Here, the flat film double film 20 uses a metal material, and it is preferable to use a synthetic resin material in order to install it in an arch shape or a curved portion.
In this way, even in the arched or vertical shape, it will have a natural water layer and have a heat collecting effect.
The double film 20 is described in detail with respect to the double film 20 so that the steel sheet or synthetic resin is bent by concave-convex, and then seam welded to each other and the black coating is applied to the surface to effectively absorb heat.
Here, the double film 20 is made of a steel sheet, but it is preferable to use a synthetic resin in a curved or arched shape.
Because the exact spacing dimensions and the amount of water supplied must be supplied correctly according to the dimensions, it is possible to form a water film layer, but when using a steel sheet it is not easy to flow naturally without applying the desired pressure.
Therefore, it is preferable to use synthetic resin, which is a material that can satisfy heat resistance, light resistance, elasticity and durability.
On the other hand, if necessary, the outer surface of the double film is coated with a solar heat absorption coating agent, the outer surface of the film is preferably coated with a heat reflection coating agent.
In this case, it is possible to increase the heat absorption efficiency, and also to prevent the freezing in winter by using a heat medium inside the double film 20 as needed.
In other words, the material of the double film can be made of iron plate when the heat collecting plate structure is a flat plate. However, even if it is slightly deformed by heat during operation, it is impossible to control the amount of water supplied and thus no water film phenomenon can be obtained.
Because the steel plate is not elastic, if the water supply is not accurate, space can be generated in the waterway, so the water flows into the solar treatment due to the water's own weight, so that the water film phenomenon is not obtained and there is no heat collection effect.
In this case, when the material of the double film is made of synthetic resin, the outer surface of the double film that receives sunlight is coated with a solar layer and a heat absorption coating agent is applied to the inner surface of the double film with a heat reflection layer so that heat does not go out. By doing so, a two-layer or three-layer structure can be manufactured at a low cost by producing a film of a suitable material according to the intended use, thereby increasing the heat collecting effect.
Here, domestic synthetic resin film production technology has a technology that can produce a five-layer structure in one layer.
In addition, the thickness of the film is within 0.7 ~ 1.8㎜, depending on the use, but very thin, and a water channel is formed between the film and the water flows.
In addition, the transparent material 10 also uses a synthetic resin.
In particular, it is preferable to use transparent acrylic and transparent glass.
Acrylic, which is a special synthetic resin material, can be installed in an arc shape, a curved shape, or any other shape.
