## Title
Building panel

## Abstract

A panel, for creating a wall/roof of a structure, may consist of a core and an outside lining, and flow-pipes located under corrugations in the lining. Each of a plurality of pipes run from one end of the core to the opposite end, and protrudes outward from those ends. The core may comprise a first side having a female-shaped indentation, and a second side having a corresponding male shaped protrusion, to permit joining together of two or more panels. The ends of alternating flow pipes of one or more panels may be coupled with an adjacent pipe using an elbow, to form a pipe coil in a-heat transfer system. With the help of headers, heat exchangers, and a liquid medium directed to flow through the pipes of a system of rooms, heat management can be accomplished using solar energy.

## Background
FIELD OF THE INVENTION
The subject of invention is a building panel, which may be used as a wall and/or roof component, built on the basis of a sandwich panel.
BACKGROUND OF THE INVENTION
Laminated panels, as everybody knows, can be applied as wall and roof elements for a building casing. Known laminated panels consist of insulating core of foamed polystyrene, polyurethane or of mineral wool and two steel sheet layers or other lining. The linings are of various types and may be made of various materials depending on the purpose. A plastic material of high resistance to the impact of chemical or biological agents can be applied to the lining and, as such, can be used for the construction of food industry facilities, including facilities with requirements pertaining to resistance in various aggressive environments such as freezing cold stores and warehouses for goods not resistant to environment temperature variations, such as foodstuffs.
Similarly, laminated panels, which may include stainless steel or aluminum sheet linings, are applied for the purposes as described herein.
Problems resulting from thermal expansion of laminated metal-sheet linings occur in the case of industrial-facilities that may have walls and roofs made of laminated panels. On sunny-days, sheet temperatures of southern-walls can reach even 80 degrees Celsius. At the same time, combustion energy of—for instance—gas, coal, wood and other combustible material, particularly gas, and electric power, is consumed in order to heat up water to be used inside building offices or production rooms.
SUMMARY OF THE INVENTION
Conclusions resulting from the observation and analysis of such situations, ended in the designing of building panels comprising a laminated panel structure, which makes it possible to use and control the heat energy, which, as mentioned above, otherwise accumulates in wall and roof panels, and is not used, but also produces disadvantageous effects which may result in panel lining thermal expansion.
The panel according to the invention is distinguished by having flow pipes located under the laminated plate lining. According to one embodiment of the invention, flow-pipes are situated on one side of the panel, and their tips protrude outside the panel.
According to another embodiment of the invention, flow-pipes are situated on both sides of the panel.
According to yet another embodiment of the invention, flow-pipes have a portion of their length situated inside the core of a sandwich panel, and pipe ends extend outside of the panel.
According to a special embodiment of the invention, execution flow-pipes can be made in the form of coil pipe, which is open at both ends. The coil pipe can be created with the help of couplings applied in order to connect flow-pipes ends.

The invention is presented in the form of examples on figures where:
FIG. 1 presents a wall panel configuration 10 with a series of flow-pipes disposed toward an exterior side of the panel, with a core having corrugations on the outer 1E and inner 1I surfaces, and with the core also having a first side with a male protrusion 1M, which, as seen in FIG. 1 and throughout each of the other figures, may comprise an extruded trapezoidal-shape, and a second side with a corresponding female-shaped indentation 1F.

DETAILED DESCRIPTION OF THE INVENTION
Thus, according to the invention the panel 10 consists of core 1, flow-pipes 2 and lining 3.
Flow-pipes 2 according to one possible embodiment are arranged to be proximate to one core 1 surface (FIGS. 1 and 3).
Flow-pipes 2 according to another possible embodiment are arranged to be proximate to both core 1 surfaces—an inner surface 1I and an outer (exterior) surface 1E (FIGS. 2 and 4).
Flow-pipes 2 according to yet another possible embodiment have a section of their length situated inside the core 1, and with the pipe ends still being brought outside core 1. These pipes can be variously shaped, for instance in the form of “U” letter inside core 1.
Flow-pipes 2 may be filled with a liquid medium 25, which may be collected in a header and be transferred to heat sinks and/or heat exchangers. The pipe ends could be interconnected, as wished, with the use of elbows 5 (FIG. 8), couplings 6 (FIG. 9), branches, etc.
In this way, the ends of particular pipes 2 can be interconnected to form accumulation system of solar energy originating heat, as well as to join these heat-transfer systems of particular panels into one or several panel systems of higher heat capacity. (See FIG. 7). Thus, the effectiveness of panels according to the present invention consists of its ability to collect heat originating as solar energy, that heats building walls and/or roofs made of such panel structures, but which is collected in headers and furthermore in heat exchangers or heat sinks, and can be used for any purpose thereafter. Application of the panels according to the present invention for use in construction provides various thermal effects simultaneously and, in particular, a temperature reduction inside buildings on sunny days, which makes it possible to limit the use of energy-consuming air conditioning systems, or to reduce the necessary power being supplied to such devices.
Collected heat of sun-heated building walls and/or roofs can be transferred, and may be used thereafter in such applications as heating glass houses such as a greenhouse, or other areas or rooms where a higher temperature needs to be maintained. An inverse procedure can be also applied, and building walls can be heated, by passing a heated media flow through the walls, which may be desirable in some cases due to the energy balance of a building heating, as it is known that with low outside temperatures, the highest heat loss occurs through large building wall surfaces.
In order to meet these purposes, pipes 2 are connected to a heating system through collectors, connected to heat exchangers, and directed to the system of rooms for heating/cooling. In a nutshell, any heat management policy can be implemented with the use of free-of-charge solar energy.
