    1 AO 20.12.1068 NL Solar thermal module for the conversion of sunlight energy into heat The invention relates to a solar thermal module for the conversion of sunlight energy into heat.
    The invention also relates to a photovoltaic thermal (PVT) device for combined conversion of sunlight energy into electrical current and heat comprising such a solar thermal module. Finally, the invention relates to a method for converting sunlight energy into electrical current and heat using such a PVT device.
    A PVT device according to the invention comprises a photovoltaic (PV) module for the PV conversion of solar radiation energy into electrical current and heat. In this case, the electromagnetic radiation emitted by the sun is collected by solar cells and at least partially converted into electrical current. Furthermore, the PVT device comprises a solar thermal module for absorbing thermal energy or heat generated at least in part by solar energy. In the solar thermal module, for example, a heat transfer medium in liquid or gas form is present in at least one tube or conduit.
    The heat generated directly and/or indirectly by the sun under the influence of solar radiation and possibly the heat generated in the PV module when the electromagnetic radiation is converted into electrical current as heat loss is at least partially transferred to the pipe or pipe and conducted into the heat transfer medium. The heat transfer medium is thereby thermally excited, i.e. the thermal energy increases, inter alia, due to the action of solar radiant energy.
    The combination of a PV module with a solar thermal module is commonly referred to as a hybrid collector (hereinafter also a collector). In a frame of the collector, the modules are arranged or arranged in such a way that the solar radiation acts directly on the PV module. Related to the direction of propagation of the solar radiation, the solar thermal module is generally arranged behind the PV module. For example, the solar thermal module may also be arranged below the PV module, since the direction of propagation of the solar radiation is substantially vertical or includes at least one vertical component.
    PV systems are regularly installed on buildings, especially on roofs, and other suitable open spaces, which convert PV solar radiation into electricity.
    2 AO 20.12.1068 GB At least part of the electrical energy required in the building or in the device can be generated directly from the solar radiation energy or from the solar radiation itself. If more energy is generated by the PV systems than is required in the building, this results in a positive energy balance of the building, because the excess energy can be fed into the energy supply grid in the form of electrical current. This reduces energy costs or, if the balance is positive, can even lead to financial income.
    The problem with using solar radiation in many geographic regions is that solar radiation is at least temporarily insufficient to fully cover a building's energy and electricity needs. Especially in the dark or in bad weather, no electricity can be generated by the PV system due to the lack of direct sunlight. Moreover, the efficiency of PV power generation is well below 50% because part of the incoming solar energy is lost as waste heat, which only heats up the PV system and its surroundings.
    In EP patent 2694885 a PV thermal module for combined energy and heat generation is described. In this, smiles are used to transfer the thermal energy from the PV module to the solar thermal module. The solar thermal module serves to absorb thermal energy mainly generated by solar energy. This involves at least partially supplying a heat pump with heat energy and electricity. This application has a number of drawbacks: - the resulting temperatures on the PV module due to radiation absorption are not supplied directly to the heat pump cycle, but are reduced by the thermal resistance of the air meander, resulting in a reduced efficiency of the heat pump; - due to the insulating air gap between the PV module and the solar thermal module, the PV module is only cooled to a limited extent during the operation of the heat pump, so that the electrical conversion efficiency is only sub-optimal. International patent application WO 2018033409 also describes a PV thermal module in which, however, the surfaces of the heat transfer units in contact with the ambient air are transverse to the plane of the PV module, so that the contact surface of the PV module with the heat transfer units is only small. Furthermore, a relatively large space of up to 50 mm between the heat exchangers offers a small total surface area for heat exchangers.
    3 AO 20.12.1068 NL The object of the invention is to design a solar thermal module for the conversion of thermal energy into heat. A further object is to design a PVT device for efficiently converting sunlight energy into electrical current. In addition, it must be possible to produce this device as efficiently as possible.
    The object of the present invention is to provide a device of the type mentioned in the preamble, ie solar thermal module (2) for the conversion of sunlight energy into heat, comprising at least one meander-shaped tube (4a) surrounded by an at least substantially seamlessly fitting extrusion profile (5a), wherein the tube (4a) is D-shaped in cross-section and the extrusion profile (5a) has a corresponding D-shape, wherein the at least one tube (4a) contains a liquid or gaseous heat carrier (3a) is located. With these shapes of the tube and the D-shape of the extrusion profile in which this tube fits exactly, the contact surface between tube and extrusion profile is increased, so that the transfer of thermal energy is optimal. The extrusion profiles can have different shapes, but a large surface with, for example, fin-like structures is favorable for a favorable heat transfer.
    The solar thermal module (2) according to the invention preferably comprises a second meander-shaped tube (4b) surrounded by an extrusion profile (5b) which fits at least virtually seamlessly, wherein the tube (4b) is also D-shaped in cross section and the extrusion profile (5b) has a corresponding D shape, the second tube (4b) containing a liquid or gaseous heat carrier (3b). More preferably, the meander-shaped tubes each alternately have a shorter and a longer bend side of the meander shape and they do not cross each other, so that the available space within the solar thermal module is optimally used. More preferably, these longer and shorter bends are D-shaped.
    Preferably, the extrusion profiles (5a, 5b) are formed from a metal or a metal alloy, in particular from aluminum. Furthermore, the tube (4a) or tubes (4a, 4b) are in particular formed from a metal or a metal alloy, in particular from copper. The liquid or gaseous heat carrier (3) preferably consists of glycol, nano-fluid or a refrigerant. Commonly used refrigerants are hydrofluorocarbons, alkanes (butane, propane, isobutane), propylene, ammonia and carbon dioxide.
    The present invention also provides a photovoltaic thermal (PVT) device for the combined conversion of sunlight energy into electrical power.
    4 AO 20.12.1068 NL and heat, comprising a solar thermal module (2) according to the invention as described above for the conversion of sunlight energy into heat, wherein the extrusion profile (5a) or the extrusion profiles (Sa, Sb) are substantially seamless mounted on a photovoltaic (PV) plate (1). This extrusion profile or profiles are preferably connected to the PV plate (1) on both sides of the tube (4a) over the entire surface, which is advantageously possible when laminating the solar thermal module (2) with two intersecting, i.e. 1 in one plane meander-shaped tubes. The short and long bend sides of the meander-shaped tubes preferably have a D-shape which fits into each other without crossing each other.
    The PVT device according to the invention is preferably contained in a frame (6), wherein the PV plate (1) and the solar thermal module (2) are arranged within the frame (6) such that the solar radiation directly hits the PV plate. (1) operates and the solar thermal module (2) is located substantially behind the PV plate (1) in the direction of propagation of the solar radiation, which is also an aspect of the invention. Since the solar thermal module (2) is mounted almost seamlessly on the photovoltaic (PV) plate (1), thermal energy can be absorbed by the extrusion profile (5a) and transferred via the tube (4a) to the heat carrier (3) which is transported in the tube (4a) and is discharged thereby.
    Another aspect of the invention is a method for converting sunlight energy into electric steam and heat in a PVT device according to the invention, wherein the incoming light energy in the photovoltaic plate (1) is at least partially converted into electric current photovoltaically. and wherein the heat, produced by the action of the solar radiant energy or otherwise such as waste heat, is absorbed by the extrusion profile (5a) or the extrusion profiles (5a, 5b) and on the at least one tube (4a) or tubes (4a, 4b) heat carrier (3a) or heat carriers (3a, 3b) carried in liquid or gaseous form is transferred.
    In the solar thermal module according to the invention, sunlight energy is very efficiently converted into heat because the largest possible surface area is brought into contact with the tube around the heat carrier via the thermally conductive material of the extrusion profiles. The tube enclosing the heat carrier is almost
    AO 20.12.1068 NL seamlessly in the extrusion profile. In addition, the tube has a D-shape so that the contact with the extrusion profile, which is also D-shaped, is as great as possible.
    A further advantage of the solar-thermal module is that it can be produced particularly efficiently, wherein tubes 5 arranged in a meander shape are fitted tightly in extrusion profiles without welding and with little soldering. The extrusion profiles themselves can also be advantageously cast over the entire long side of the meander shape of the tube in one mold.
    A photovoltaic thermal (PVT) device for combined conversion of light and thermal energy into electric current forms a further aspect of the invention. This device comprises the solar-thermal module as described above, wherein the meander-shaped extrusion profile or the extrusion profiles are preferably mounted almost seamlessly, for example by gluing, on a photovoltaic plate (FV) such as for example a solar panel. Furthermore, each tube lies in the plane of the extrusion profile which is parallel or substantially parallel to the photovoltaic plate (FV). With this PVT device, sunlight energy can therefore be converted into both electrical current and heat. Moreover, especially by applying the large surface area of the extrusion profiles around the pipes with heat carriers, heat can also be efficiently recovered from condensation of water vapour, from wind and from air. The solar thermal module according to the invention can also be used advantageously in other ways, such as for example in a vertical screen such as a garden fence.
    The PVT device according to the invention can be placed in a frame in an efficient manner in that the frame with the PV glass plate on the outside faces the sun during use, in addition to the frame mounted thereon inside the frame on the inside, for example by means of lamination. , solar thermal module according to the invention. Energy can also be extracted advantageously from the outside of the glass plate in the form of condensation, rain and wind.
    The present invention is further elucidated with reference to the following drawings of the solar thermal module (2) according to the invention.
    Figure 1a: Oblique top view of the photovoltaic thermal (PVT) device with the solar thermal module (2) with D-shaped tubes (4a, 4b) in meander shape, seamlessly attached to PV plate (1) via the extrusion profiles (5) , included in a framework (6).

    6 AO 20.12.1068 NL profiles shown separately (not attached).
    Figure 2: Oblique front view of D-shaped two extrusion profiles (5) with fin-shaped projections.
    The figures are schematic and not drawn to scale. Corresponding parts are indicated in the figures with the same reference numerals.
    Figures 1a and 1b show the solar thermal module according to the invention, in which the meander-shaped structure of the tubes is clearly visible. Figure 1b in particular shows how the extrusion profiles can be fitted seamlessly around the meander-shaped tubes. The meander shapes each alternately have a shorter and a longer bend side and do not cross each other. In this way the falling tubes lie in one plane and can be attached seamlessly to the PV plate. By applying this structure, optimum heat transfer from the environment to the heat carriers takes place. This structure also provides optimum space for, for example, a junction box (7), within which electrical connections are located.
    Figures 2a and 2b show two examples of extrusion profiles with their D-shape fitting seamlessly around the D-shaped tubes as used in the solar thermal module according to the invention. But also the use of other extrusion profiles that fit around D-shaped tubes which lead to efficient heat transfer and thereby to efficient conversion of sunlight energy into electric current and heat fall within the scope of protection of the invention.
    Although the invention has been elucidated above with reference to a few embodiments and application, it will be apparent that the invention is by no means limited thereto. On the contrary, many variations are possible for a skilled person within the scope of the invention.
