The present invention relates to a composite panel in which a solar cell and a heat insulating panel are integrated, and more particularly, to a solar cell and a heat insulating composite panel which can prevent the degradation of the solar cell due to heat rise and be used as a finishing material of a building. .

Solar cells have been used for a long time since they are made of large panel-like structures for use in buildings as electrical energy sources. Existing solar panel has installed a separate supporting structure on the roof or roof of a building, and a plurality of solar panels are mounted on the structure, and the building uses the electrical energy obtained therefrom.

However, the solar cell panel installed in this way was inconvenient to go through a separate installation process from the building construction. In other words, if you want to install solar panels on the roof structure during building construction, you need to form a finishing material, perform waterproofing, install a panel mounting structure separately, and finally install solar panels. It was.

The use of solar panels through structures separate from buildings has problems such as difficulties in construction and installation, and increase in manufacturing and installation costs. Therefore, the role of solar cells in the national energy utilization has been reduced.

If solar cells can be used as part of a building, various advantages can be obtained in terms of ease of construction and energy utilization. However, if the solar cell itself is to be used as a part of the building, for example, an exterior finish of the building, there are various problems to be solved. First, the solar cell panel itself is difficult to be used as the exterior finishing material of the building alone due to its low structural strength. In addition, the solar cell has a problem that the power generation performance is lowered as the temperature of the solar cell itself is increased by the solar heat, when used as a finishing material of the building, there is a need for an effective means that can suppress such a temperature rise.

On the other hand, in order to utilize the solar cell as part of the building, construction convenience, ease of maintenance and maintenance, and various other problems must be solved.

The present invention has been made under such a technical background, an object of the present invention is to provide a solar cell and a heat insulating composite panel having a simple structural strength.

Another object of the present invention is to suppress the heat rise of the solar cell in the composite panel so that the solar cell performance can be stably maintained for a long time.

Still another object of the present invention is to ensure the economics that the construction of the composite panel itself is easy, as well as excellent waterproof performance when used as a finishing material in the building, the overall construction cost, maintenance costs are reduced.

Another object of the present invention is to provide a composite panel that can be utilized in the building to maximize the energy utilization of the building and improve the added value of the building.

Other objects and features of the present invention will be more specifically set forth in the following detailed description.

In order to achieve the above object, the present invention is provided with a heat insulating panel that includes a heat insulating material therein, and a fixing portion so that one side can be fixed to one surface of the heat insulating panel, the other side is provided with a seating portion on which the solar cell panel is seated And a support frame formed at a predetermined height such that a space portion is formed at a predetermined interval between the heat insulation panel and the solar cell panel, and the composite panel including a solar cell panel mounted to the seating portion. The side end in the first direction of the composite panel is a closed structure, the side end in the second direction perpendicular to the first direction is formed in an open structure, to enable air flow or heat flow in the space inside the composite panel It provides a building finishing solar cell and a heat insulating composite panel, characterized in that to prevent the heat rise of the solar cell panel.

The support frame may be coupled to the insulation panel at a predetermined distance from at least one end of the first direction side of the composite panel.

The support frame is formed to extend more than the end of the heat insulation panel at any one of the second direction side end of the composite panel, it is preferably formed shorter than the end of the heat insulation panel at the other side of the second direction side. .

The seating portion of the support frame is preferably L-shaped, and is formed in both side ends in the first direction of the composite panel and in both side ends of the second direction perpendicular to the first direction, respectively, in the second direction of the composite panel. It is preferable that the height of the seating portions formed at both side ends is lower than the seating portions formed at both side ends in the first direction.

In addition, the present invention provides a building finishing composite panel system comprising a plurality of composite panels mounted in a front and rear and right and left and connected to the support structure installed in the area exposed to the outside, such as the roof or wall of the building. .

The composite panel according to the present invention has the advantage that the heat rise of the solar cell panel is suppressed to maintain excellent solar power efficiency in the long term. In addition, since the insulation panel and the solar cell are simply integrated, the production is simple, and the construction is not only convenient for the building, but also easy to repair and manage. This integrated system not only reduces the manufacturing cost of the composite panel, but also facilitates the construction of the building, thereby reducing the construction cost and the construction period. In particular, the composite panel corresponds to a lightweight material (weight of about 1/18 of the concrete), so when used as a finishing material, such as the roof of the building can contribute to the structural stability of the building. In addition, by using the heat generated during the solar power generation as the internal heating of the building to maximize the thermal efficiency of the building, thereby improving the added value of the building.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 shows an insulating panel which is the first component of a composite panel according to the invention. In one embodiment, the heat insulating panel 10 is formed of a sandwich-type laminated structure in which the heat insulating member 12 is inserted between the metallic upper plate 11a and the lower plate 11b. The heat insulating member 12 is foamed and inserted into the urethane material having excellent heat insulating performance, and other additional materials effective for heat insulating may be included. The heat insulating panel 10 is only one example of constituting the composite panel according to the present invention, and the present invention is not particularly limited in terms of the structure, the material, and other forms of the heat insulating panel.

The insulating panel 10 is preferably in the form of a plate for complexing with the solar cell panel described later, and the perforations 11 'as shown in FIG. Can be formed.

2A and 2B show a composite structure 20 in which a solar cell panel 30, which is a second component of the composite panel according to the present invention, is coupled to a support frame. The solar panel 30 is preferably a thin plate-like structure formed by integrating a plurality of unit solar cells on one substrate. The present invention further includes a support frame as a medium for compounding such a plate-shaped solar cell panel 30 with the heat insulation panel shown in FIG. 1. The support frame may be formed in various forms, and in the preferred embodiment of the present invention, a support frame in which the first support frame 21 and the second support frame 22 organically work is proposed. The first support frame 21 and the second support frame 22 may be separated from each other as shown in FIG. 2A, or alternatively, two frames may be structurally connected to each other.

The first support frame 21 and the second support frame 22 are formed in the L-shaped seating portion 24 so that the solar cell panel 30 is seated and fixed on the upper side, the lower insulating panel The fixing part 25 is formed so that it may be fixed with the 10. The shape of the seating portion 24 and the fixing portion 25 can be seen more clearly in Figure 2b showing the A-A cross section of Figure 2a. The seating part may be formed in addition to the L-shaped, but the L-shaped seating part is easy to mount and detach the solar cell panel in the composite panel, which is effective for maintenance and maintenance, especially in a complex system in which a plurality of composite panels are connected. It is very advantageous when only some solar cell panels are separated and maintenance is required.

It is preferable to maintain a predetermined interval between the seating portion 24 and the fixing portion 25, this interval is the space between the heat insulating panel 10 and the solar cell panel 30 is fixed and seated by a support frame The portion is then formed to provide an air fluidized bed or a heat fluidized bed inside the composite panel. This space acts as a direct means for maximizing the efficiency of the solar cell panel intended in the present invention. Reference numeral 24 'denotes a buffer member or an adhesive member that performs a buffering function or a fixing function required when the solar cell panel 30 is seated on the seating portion 24.

The support frame composed of the first support frame 21 and the second support frame 22 is a solar cell panel (see FIG. 2A) in which a solar cell panel 30 is seated on the upper part of the support frame 21 to form a structure. 30) When the two directions on the surface, that is, the I direction corresponding to the rectangular shape of the solar cell panel and the II direction, which is the width direction of the solar cell panel, are distinguished from each other, at least one end thereof has a closed structure. It is preferable. In FIG. 2A, both ends of the solar cell panel in the width direction, that is, the II direction are formed. This shortened structure can be clearly seen from the side view of the supporting frame shown in FIG. 2C and the composite panel 40 in which the heat insulating panel 10 and the solar cell panel 30 are integrated. On the other hand, in the cross-sectional view of FIG. 2B, both ends of the solar cell panel are seated on the first support frame 21 and the second support frame 22, and the lower region of the solar cell panel is an open structure. It can be seen that. This open structure can be seen from FIG. 3B when the composite panel 40 of FIG. 3A is seen from the front. The space portion indicated by reference numeral 42 corresponds to the open structure.

As such, when the inner space 42 of the composite panel is formed in a structure that is open in a specific direction and closed in another direction, a plurality of unit composite panels are connected in a grid to form a system. For example, when multiple composite panels are used as finishing materials in areas exposed to the outside, such as roofs or walls of buildings, they enable air flow or heat flow inside the entire system. Particularly, when the open structure is formed in one direction, the air flow space or the heat flow space is continuously formed between the unit composite panels, thereby further increasing the performance of the solar cell panel by preventing heat rise caused by the solar cell panel. In addition, the solar heat generated directly from the solar cell panel or passing through the solar cell panel to the inside of the composite panel can be transferred to the inside of the building for use in internal heating or cogeneration system that can be installed inside or outside the building. It can provide an effective advantage.

In FIGS. 2A to 3B, both ends of the solar cell panel in the width direction, that is, the II direction are closed. Alternatively, the solar cell panel may be formed such that both ends of the solar cell panel are in the longitudinal direction, that is, in the I direction. .

Meanwhile, in FIG. 3B, the height D of the space 42 between the heat insulating panel 10 and the solar cell panel 30 greatly affects the performance of the solar cell panel. As the height D of the space portion 42 increases, the heat outflow of the solar cells is easily suppressed by the outflow of heat generated from the solar cell panel, so that the performance of the solar cell panel is improved. Since this can be made small, an appropriate range is required. In the Example of this invention, the height D of the said space part 42 was made into the range of 5 cm-30 cm. However, the optimal height of the space may be influenced by the structural form of the building in which the composite panel is installed, the natural environment of the area where the building is constructed, and other factors, so that the optimal height may be selected in the actual installation site. .

Next, the method in which the composite panel is connected to another composite panel adjacent in the longitudinal direction or the width direction will be described.

First, referring to FIG. 4A, the lengthwise direction of the composite panel, that is, the connection in the I direction in FIG. 2A, is illustrated in which one end of one composite panel overlaps one end of another composite panel and overlaps with each other. Able to know. One end of the first support frame 21a and the second support frame 22a of one composite panel has a 'b' shape (part of reference numeral 27 in FIG. 2C) with the upper part partially cut, and the other composite panel One end of the first support frame 21b and the second support frame 22b can be seen that the lower portion is partially 'c' shaped (reference numeral 26 in FIG. 2C). As described above, the ends of the two composite panels are stacked to overlap each other, and the solar cell panels 30a and 30b seated thereon are partially overlapped. The cross section of such a laminated structure is shown in more detail in the cross-sectional view of FIG. 4B. One end of the solar cell panel 30a of the first composite panel overlaps and one end of the solar cell panel 30b of the second composite panel overlaps, and this overlapping structure is, for example, a composite panel building. It is possible to run down rainwater when it is constructed as a roof finish. That is, in the traditional Hanok structure, the roof tiles are stacked on each other and flow in one direction, but similar to the structure that does not break into the inside of the Hanok. In FIG. 4B, reference numerals 24a and 24b denote seating portions of separate L-shaped partial frames supporting one end of each solar cell panel 30a or 30b.

The seating portions 24a and 24b correspond to seating portions (see FIG. 3A) installed at both ends of the composite panel in the longitudinal direction, that is, the I direction in FIG. 2A, and both sides of the composite panel in the width direction, that is, the II direction. The height is formed low compared with the mounting part 24 provided in the seat. The reason for this is to make it easier for the rainwater to flow down from the two composite panels that are connected, and also to prevent foreign matters from accumulating on the seating unit so as not to block the solar cell panel.

Reference numerals 24a 'and 24b' denote buffer members or adhesive members for mounting the solar cell panels, respectively. On the other hand, reference numeral 28 denotes a shock absorbing member that mitigates the impact while preventing the two solar cell panels 30a and 30b from contacting each other. The buffer member 28 is a small space between the two solar panel (30a, 30b) in particular serves to prevent rain water and the like to enter by the capillary phenomenon.

As such, when the two composite panels are connected to each other, the inner space portion 42 of each composite panel is connected to each other. That is, a continuous space is provided so that a series of open structures are formed inside the composite panel system. This continuous open structure acts as a passage for rapid air flow or heat flow inside the overall composite panel system, effectively preventing the heat rise of the solar cell.

4A and 4B, as the ends of the two composite panels are stacked and connected to each other, there is a fine step 43 between the insulation panels 40a and 40b. It is desirable that the step 43 be as small as possible because it is stable to a supporting structure (for example, a bar-shaped steel structure) that serves as a basic support when the composite panel is constructed as a finishing material in a building. This is to fix it.

5A and 5B show the connection of two adjacent composite panels in the width direction of the composite panel, that is, the II direction in FIG. 2A. In this case, it is not necessary to connect the adjacent composite panel in a laminated structure, and it is sufficient to fix the support structure 50 by bringing it into close contact with each other so as not to be spaced apart from each other. The fixing method to the support structure may have various methods. In the embodiment of the present invention, an exposed area 15 is provided at one end of the insulating panel 10 so as not to overlap with the supporting frame 22, and fixed to the exposed area. The fastening means of the bolt 16 was used to couple to the support structure 50. Moisture, such as rainwater, may penetrate through a minute gap between two adjacent composite panels, and thus, means such as a waterproof cap 29 may be further included between the two support frames 21 and 22 of the adjacent composite panel.

In the above, the lengthwise and widthwise connection between two unit composite panels has been described. However, such a system is connected back and forth and left and right to connect a plurality of composite panels in the form of a grid. It can be used as a finish for external exposed areas.

The above-described embodiment is only presented a preferred example to aid the understanding of the present invention, it will be understood by those skilled in the art that various modifications and improvements can be made within the scope of the technical spirit of the claims to be described later.

As described above, the present invention can be utilized as a finishing material of the building by forming a solar cell panel and a heat insulation panel integrally, it is possible to prevent a decrease in efficiency due to the heat rise of the solar cell in a composite system in which the solar cell panel is integrated. In addition, it is possible to maximize the energy efficiency of the building by actively using the heat energy generated in this complex system. In addition, the construction cost can be reduced by constructing a composite panel as a finishing material of the building, and the construction difficulties generated by separately installing the insulation panel and the solar cell panel can be solved at once, and the energy utilization of the building is maximized. Maintenance costs can also be lowered, greatly improving the added value of the building.
