    FIELD OF THE INVENTION
    The present invention relates to a parabolic solar collector comprising a linear parabolic mirror and a tubular device traversed by a heat transfer fluid is placed at the focus of the linear parabola so that the parabolic mirror concentrates the incident solar rays on the tubular device, and provide heat to the coolant. The present invention relates more particularly to such a solar collector comprising a transparent and mechanically resistant outer enclosure. The present invention relates both to a photovoltaic solar collector and a solar thermal collector.
    PRIOR ART
    [0002] Solar collectors are known which correspond to the definition given above. Patent document FR 2 568 991, in particular, describes a low-grip solar collection and storage device comprising a linear parabolic mirror designed to pivot around a hollow pylon forming the rigid vertical axis of a tower. cylindrical whose base constitutes a technical room and a thermal storage space. The walls of the cylindrical tower consist of elements of transparent plastic materials assembled between superimposed circular rails. The rails are themselves suspended from the pylon by a first set of tensioners and stowed to the base of the cylinder by other tensioners. This known construction has certain disadvantages. On the one hand the described installation is large, 6 meters in diameter and 20 meters high, which makes it difficult to integrate with existing buildings and structures. In addition, the construction or assembly of such a solar collection and storage device obviously represents considerable work.
    BRIEF SUMMARY OF THE INVENTION
    An object of the present invention is therefore to overcome the disadvantages of the prior art which have just been described, and in particular to provide a solar collector easy to install and uninstall, and which can even be transported in one piece without the need for disassembly. The present invention achieves this goal by providing a parabolic solar collector according to the appended claim 1.
    According to the invention, the transparent enclosure is self-supporting. In other words, it is rigid enough to resist deformations and to ensure the structural integrity of the solar collector, even when it is detached from any support. It will be understood that an advantage of this feature is that the solar collector of the invention can be moved without the need to disassemble it beforehand. Its maintenance and commissioning are therefore greatly facilitated. In addition, the tubular device is fixedly mounted inside the enclosure. It therefore does not rotate on itself, which greatly simplifies the connection of the circuit lines for the heat transfer fluid. Finally, according to an advantageous variant of the invention, the tubular device passes through the enclosure from one side to the other, so that its two ends open out on either side of the solar collector. This last characteristic lends itself particularly well to the realization of installations comprising a plurality of solar collectors connected in the same heat transfer fluid circuit.
    The linear parabolic mirror is rotatably mounted on the tubular device. It is provided with an energy autonomic orientation device arranged to support mechanically on a fixed part of the installation. The possibility of rotation of the linear parabola with respect to the tubular device is necessary to orient the mirror facing the incident solar rays. The rotation of the mirror can be very slow. According to the invention, the orientation device is disposed inside the enclosure and is integral in rotation with the linear parabolic mirror. The orientation device is connected to a power source which is also contained inside the enclosure. This feature makes the guidance device standalone. Advantageously, the energy source is also integral in rotation with the mirror so as to remain stationary relative to the orientation device. With this feature, the wiring of the orientation device can be particularly simple.
    According to an advantageous embodiment of the invention, the outer enclosure has an axis of symmetry and therefore has the shape of a solid revolution. It will be understood that giving the enclosure a solid form of revolution gives it greater rigidity. In addition, according to an advantageous variant of this embodiment, the tubular device is mounted concentrically to the axis of symmetry of the solid of revolution. Indeed, this arrangement makes it possible to limit as much as possible the external bulk of the enclosure while at the same time retaining sufficient clearance for the linear parabolic mirror to be free to rotate.
    According to a very advantageous variant, the enclosure has the shape of a solid revolution closed at each of its ends by a flange. It will be understood that the solid of revolution forms with the two flanges an enclosure enjoying a high structural stability. According to this variant, each flange still has a central opening arranged to allow the passage of one end of the tubular device. Preferably, the opening of the flanges is further arranged to allow each end of the tubular device to be fixed to the enclosure. Thus, the tubular device is integral with the two flanges, which further strengthens the structure of the sensor. It will be understood that the transparent enclosure plays the role of a chassis inside which all the rest of the construction is fixed.

    DETAILED DESCRIPTION OF AN EMBODIMENT
    FIG. 1 is a perspective view showing a parabolic solar collector 1 according to a particular embodiment of the invention. It can be seen in the figure that the sensor is housed in a transparent protective enclosure 7. The enclosure is designed to enclose and protect all sensitive and fragile parts of the solar collector. In the illustrated embodiment, the protective enclosure 7 has a cylindrical shape and is preferably made of glass. The cylindrical shape gives the enclosure a good structural stability, and this stability is increased by the presence of two glass flanges 10 and 11 which are glued to both ends of the cylindrical tube. It can be seen again that the two flanges have their center crossed by a tubular device 4 which is concentric with the axis of symmetry of the cylinder. The tubular device 4 is provided to be traversed by a coolant (not shown). Fig. 1 still shows in transparency, inside the enclosure, a linear parabolic mirror 2 which is rotatably mounted on the tubular device 4, two counterweights 17 for the rotating mirror, and an energy-autonomous orientation device 9 which is worn by the parabolic mirror. In the illustrated embodiment, the orientation device is equipped with a wheel arranged to bear on the inner surface of the chamber 7. However, it will be understood that, according to other embodiments, the orientation device could rely on another fixed part of the installation. In particular, it could rely on the tubular device 4. In this case, the rotational movements of the parabolic mirror relative to the tubular device could advantageously be produced by an ultrasonic motor similar to those which are commonly used in the autofocus devices of some cameras. Finally, it will be noted that the solar collector 1 is illustrated in a horizontal position, supported by a cradle made of metal tubes 20. However, it will be understood that the solar collector according to the invention can operate in all orientations (horizontal, vertical, inclined).
    Figs. 2A and 2B are schematic views of the cylindrical enclosure 7 transparent solar collector. As already mentioned, in the illustrated embodiment, the protective enclosure consists of a cylindrical glass tube, the two ends of which are closed by flat circular flasks 10 and 11 also made of glass, which are assembled by gluing to the cylinder. The connection of the flanges and the cylinder is protected by two metal flanges 21 which are glued to the flanges and the cylinder by means of, for example, a silicone mastic. These flanges also make it possible to secure the solar collector to a support (the cradle 20 of Fig. 1 for example). The center of the flanges 10 and 11 is used for fixing the tubular device 4. In the illustrated example, this fixing is performed by an aluminum flange 22. The glass used for the protective enclosure 7 (including the flanges 10, 11) should preferably be as transparent as possible, providing the best radiation transmittance over a wavelength range of 250 to 2500 nanometers. From the point of view of transmittance, calcium fluoride glass is one of the most suitable, but it is expensive. Quartz glass is almost as good and cheaper. Borosilicate can also be envisaged.
    The chamber 7 of the solar collector is preferably waterproof. However, it will be understood that the interior of the enclosure is subjected to temperatures higher than the external temperature during operation of the solar collector. As a result, pressure differences between the inside and the outside of the enclosure are inevitable. These differences, in theory, could burst the glass enclosure. Several alternative variants can be envisaged to overcome this difficulty. First, in accordance with the embodiment illustrated by the figures, it is possible to equip the enclosure with two safety valves. A first valve to limit overpressure inside the enclosure and a second valve in case of overpressure outside the enclosure. According to an alternative variant, an expansion membrane mounted on the enclosure could be provided. It will further be understood that no means of equalizing the pressure is really necessary, as long as the enclosure is sufficiently solid. In the same vein, one could still create a partial vacuum inside the enclosure, so that the pressure difference is always in the same direction.
    Figs. 3A and 3B have schematic views, respectively in perspective and in cross-section, of the linear parabolic mirror of the solar collector. A particularity of the linear parabolic mirror of the solar collector embodiment which is the subject of the present example is that the linear focus of the dish coincides with the axis of symmetry of the protective enclosure 7.
    The linear parabolic mirror 2 must have a weight as low as possible so as to limit the consumption of electrical energy necessary to control its orientation. Figs. 3A and 3B illustrate an example of construction of the linear parabola. According to this example, the linear parabola 2 consists of an aluminum sheet whose thickness can be 0.2mm. The aluminum sheet is given its parabolic form by stamping. The back of this sheet can be stiffened by arches 23 made of injected aluminum and machined. The arches are assembled to the sheet, for example by gluing, and ensure the holding of the parabolic form. The concave part of the linear parabola 2 has a surface that must ensure the reflection of solar radiation to the linear focus. For example, a parabolic mirror made as explained above and having a reflective surface of 0.575 m 2 weighs about 680 grams.
    Figs. 4A and 4B are schematic sectional views showing in detail the tubular device 4 of the solar collector 1. The tubular device has the main role of transforming the energy of the solar radiation into thermal energy. The circulation of a coolant (not shown) through the tubular device can transport this energy to the outside of the solar collector to be used. As has already been said, the tubular device is concentrically arranged at the linear focus of the parabolic mirror 2. When the dish is well oriented, it therefore concentrates the solar radiation on the tubular device. In a manner known per se, the latter may comprise an absorption tube 25 of metal (for example stainless steel) covered with a layer promoting the absorption of light energy (for example a black chrome treatment) and a glass insulation tube 26 closed at both ends and surrounding the absorption tube. A high vacuum is achieved in the volume formed between the absorption tube 25 and the insulation tube 26 so as to create a very good insulation between the absorption tube and the outside. In the example illustrated, it will be noted that the glass insulation tube 26 is closed at one of its ends by a flange 27. In addition, in order to make it possible to balance the difference in expansion between the insulation tube 26 and the absorption tube 25, the other end of the glass tube is closed by a compensator 28.
    FIG. 5 is a partial sectional view showing more particularly the attachment of the tubular device 4 to the glass flange 10 of the chamber 7 of the solar collector. We can see in fig. 5 that, in the illustrated example, the attachment of the tubular device 4 to the flange 10 is formed by an aluminum flange 22, the flange 22 is glued to the glass flange 10 by means of a silicone mastic supporting the high temperature (~ 200 ° C). This flexible bonding makes it possible to reduce the stresses associated with the difference in expansion between glass and aluminum. The connection between the glass flange 10 and the insulation tube 26 of the tubular device 4 is made by O-rings 29 supporting the high temperature (~ 200 ° C and Viton for example). A small aluminum compression flange 30 makes it possible, by means of a mechanical clamping, to compress the O-ring 29 so as to center and fix the insulation tube 26 while allowing a certain flexibility of the assembly and its sealing. The assembly is constructed to create a cold bridge between the inside of the protective enclosure 7 and the outside so as to evacuate a little heat from the inside of the protective enclosure to the outside , in order to limit the temperature inside the protective enclosure.
    Figs. 6A and 6B are views, respectively in perspective and front view, showing how the linear parabolic mirror 2 is pivoted on the tubular device 4 by means of two radial bearings 12. The parabolic mirror 2 can rotate around the tubular device 360 °. For this purpose, the two radial bearings each comprise a ball bearing. These bearings allow the rotation of the linear parabola and position it precisely with respect to the tubular device during all its rotation. The movable outer part of the ball bearings is integral with the linear parabola. The inner part is, when it is, clamped on the tubular insulation tube 26 of the tubular device by means of O-rings giving this connection a certain flexibility. One of the two ball bearings has a radial holding function. When to the other, it must provide a function of radial and axial retention. Indeed, the solar collector should preferably operate in all positions, from horizontal to vertical. One of the two ball bearings is arranged to compensate for the differences in dilation between the insulation tube (glass) and the linear parabola (aluminum).
    Figs. 7A and 7B are schematic views similar to FIGS. 6A and 6B, but which also show the external enclosure 7 and the orientation device 9 of the mirror 2. To orient the parabolic mirror 2 perpendicular to the solar radiation, it is necessary to rotate the mirror relative to the fixed parts of the sensor 1. In the present example, the angular displacement of the mirror is provided by an electric motor which is part of the orientation device. The electrical energy consumption of this engine must be as low as possible. As already mentioned, the parabolic mirror is pivoted through the radial bearings 12 which are equipped with ball bearings. Ball bearings require very little energy to "peel off" them during startup, which ensures the accuracy of rotation.
    It is absolutely necessary to avoid introducing materials that can evaporate inside the protective enclosure 7, because the vapors then condense on the inside of the protective enclosure, on the reflective part parabola 2 and the insulation tube 26 glass, which may reduce the efficiency of the sensor. Ball bearings are therefore preferably used which can operate dry, that is to say without grease or oil. Remember that these ball bearings rotate very slowly, in principle one rotation per day. Preferably, the main parts of the radial bearings 12 are made of aluminum. However, to avoid corrosion problems, the ball bearings are preferably glass beads and not steel. Indeed, steel is aluminum do not mix (electrochemical corrosion problem).
    It will be understood that the linear parabolic mirror 2 is not balanced with respect to its axis of rotation. To simplify the orientation system, optimize its electrical energy consumption and increase its accuracy, it is useful to balance the linear parabola and to reduce the center of gravity of the assembly on the axis of rotation, so on symmetry axis of the protective enclosure. In the illustrated example, counterweights 17 are used to balance the mirror. The protective enclosure 7 being cylindrical, its volume makes it possible to place the counterweights opposite the parabola 2. The parabola being of very light construction, its orientation system being very small, the mass of the counterweights 17, respectively their volume, will be weak. The counterweights may be made of steel, a much denser material than aluminum, and they are preferably placed very close to the inner surface of the protective enclosure so as to maximize the lever arm. Note also that in the example shown, the counterweights 17 are also used to accommodate two small solar cells that allow the supply of electricity to the orientation device 9. This location is very favorable for solar cells, because they are so always oriented perpendicular to the solar radiation.
    Figs. 8A, 8B and 8C are schematic sectional views showing three particular orientations of the linear parabolic mirror 2 and illustrating for each orientation the reflection of incident solar rays. The solar collector is intended to capture solar energy. If for any reason we decide to stop the production of energy, the linear parabolic mirror 2 can be turned so as to no longer concentrate the solar radiation on the tubular device 4, which will have the effect of stopping the production of energy . For this it is sufficient to provide a management electronics (not shown) for controlling the orientation device 9 (FIG 7B) so that it directs the linear parabola so that it no longer focuses the radiation solar on the absorption tube 25 (Fig. 4B).
    In the illustrated embodiment, the orientation device 9 is not connected to the outside of the enclosure 7 by wiring. However, it is possible to provide a radio system (for example according to the Bluetooth® standard) for communicating from the outside with the management electronics of the orientation device 9. Under these conditions, the electronic management system must be equipped with a receiver. It is also preferably equipped with a transmitter for sending information concerning the solar sensor, for example signaling a malfunction.
    The tubular device 4 of a solar collector 1 according to the invention is intended to be traversed by a heat transfer fluid 5. For this purpose, the absorption tube 25 of the tubular device 4 of at least one solar collector 1 must be integrated in a circuit 6 for heat transfer fluid. The number of solar collectors whose absorption tubes are part of the same heat transfer fluid circuit is theoretically not limited. The tubular devices, or more precisely their absorption tubes, can be connected in series, in parallel or a mixture of the two. It will be understood that each solar collector 1 is arranged to supply heat to the coolant 5 which flows through the tubular device 4. FIG. 9A schematically illustrates a circuit 6 for coolant 5 associating five solar collectors 1 connected in parallel. Fig. 9B schematically illustrates a circuit 6 for heat transfer fluid 5 combining six solar collectors 1 connected in series.
    FIG. 10 is a perspective view showing the series connection of several solar collectors identical to that of FIG. 1. It will be understood that the ends of two absorption tubes can be connected to each other in any manner known to those skilled in the art. However, the connection between two absorption tubes will preferably be a connection easy to make and easy to undo. The two ends of the absorption tubes may for example each end with a nose provided to be inserted by force into a fitting tube of a deformable material. It will be understood that such a connecting tube may be used to connect the ends of the absorption tubes of two solar collectors. To prevent excessive heat loss, the fitting tube is preferably further surrounded by a sleeve of a material both flexible and good thermal insulator, such as foam for example.
    It will further be understood that various modifications and / or improvements obvious to a person skilled in the art can be made to the embodiment which is the subject of the present description without departing from the scope of the present invention defined by the appended claims. In particular, the invention is not limited exclusively to a solar thermal collector, but also relates to a photovoltaic solar collector. It will be understood that it is possible, for example, to replace the tubular device 4 illustrated in FIGS. 4A and 4B by a pipe covered with photovoltaic cells.
    It is known that the efficiency of photovoltaic cells decreases with temperature. Under these conditions, instead of using the heat transfer fluid to bring heat to any device, one can use a heat transfer fluid provided for cooling the photovoltaic cells. For example, you can pump water into a river and use it as a coolant. On the other hand, the function of the glass insulation tube 26 surrounding the absorption tube 25 is to allow the temperature of the absorption tube to rise as much as possible. It will therefore be understood that, in the case of a photovoltaic solar collector, it is preferable for the tubular device not to include such an insulating tube. It should however be noted that certain embodiments of the invention are solar thermal solar collectors which comprise an insulating tube.
