Description

Description Modular solar panel with rotating collectors for windows and facades
Technical field
Solar panel, transparent on the front and back sides, internally furnished with thermal revolving collectors for the production of thermal energy, to be installed in place^of the normal glass windows, using their regular chassis, or as a continuous facade on industrial sheds and houses.
Technique state
The sun is an inexhaustible resource for man. The use of technologies which exploit this resource can give a big contribution to the solution of problems tied to the thermal pollution, with an abrupt decrement of CO2 emissions in the air. The whole world is actually focusing to develop technologies and products which use the solar energy both to heat, eventually at high temperatures, liquids or gases, and to directly produce electrical energy.
The most known are thermal sun panels, essentially composed of a box with an upper transparent surface and a lower opaque one; inside there is a serpentine or a dark catching plate in which a fluid, generally water, flows. These panels are assembled on the roofs of houses and industrial sheds or on platforms for the purpose of heating the fluid with the solar radiation. To avoid they can be shuttered because of a storm or a strong wind, they are fixed on the site, with a optimal inclination which depends on the latitude of the place, usually 45-60° faced south, to take advantage from the solar radiation. It would be better the solar panel could follow the sun by varying its inclination above the horizon to collect optimally the solar ardiation.
The motorization of these panels is not convenient, because they are heavy and as stated they must be well fixed; a system of inclination of the whole panel would involve higher costs not justified by the energetic return.
Purposes and advantages of the invention
The purpose of this invention is to make a solar panel using air as fluid, and having only an active movable collecting part, simply said the collectors, in order to optimize solar radiance.
Other purpose of this invention in agreement with the previous one where the movement of the active movable collecting part can be obtained manually or with an automated software controlled device, by means of a solar clock.
Other purpose of this invention in agreement with the previous one where the active collecting part, i.e. the collectors, are made of high thermal conductivity material, and the two sides of the collectors are respectively one of very dark colour and the other one of very clear colour.
Other purpose of this invention in agreement with the previous ones is to make a thermal solar panel with revolving collectors having the characteristic to be transparent on the main - front and back - sides, in order to be installed as a normal glass window inside a chassis, or as a continuous front facade.
Other purpose of this invention in agreement with the previous ones is that the internal collectors can rotate along their elongation axis of symmetry, by 360° allowing to be used, in the case of window like installation , also as darkening or shady curtain as protection from excessive light, a typical condition when the sun is below 45°of the horizon.
Other purpose of this invention in agreement with the previous ones is that the thermal solar panels with revolving collectors for windows and continuous facades have the possibility to be embedded each other to synchronize the movement of the collectors in order that an eventual ribbon window or continuous facade can have a single colour at the observer's view, contributing to a less intrusive architectural impact; the collectors in such a position don't take away excessively from the chromatic effect given from the colour or the aesthetic of the building.
Description of the Drawings and way to carry out the invention
These and other characteristics as well as advantages will result evident from the following description and from the enclosed drawings showed for just indicative purpose and not limitative in which:
Figure 1 shows a front view of the thermal panel with revolving collectors.
Figure 2 shows an orthogonal lateral view of the thermal panel with revolving collectors. Figure 3 shows an orthogonal view from top of the thermal panel with revolving collectors.

Figure 9 shows the end- closure of the thermal panel with revolving collectors.
Figure 10 shows a front view of the panel with revolving collectors with photovoltaic panel.
Figure 11a and 11b show details of the panel with revolving collectors with manual mechanism.
Figure 12 shows an example of application of the panel in place of the regular window glass of a house.
Figure 13 shows an example of application of the panel by simulating the shutters of a house. Figure 14 shows an example of application of the panel as continuous facade of a house.
Figure 15 shows an example of application of the panel alternated with the windows of a house.
In accord to the enclosed drawings, (1) indicates the panel object of this invention, (2) the front surface made of a transparent glass, (3) the back ' surface made of a transparent glass, (4) the perimetral structure made of a metal section; the outtake/intake warm air hole (5) is placed in the middle of the upper part of the back side (3), the intake/outtake cold air hole (6) is in the middle of the lower part of the back side (3), so to perform warm and cold air exchange in the room; both holes have an anti-dust filter (14).
Within the panel (1) collectors (7) are placed that are made of a high heat conductivity plane plate with the surface of the two sides of the plate, front and back, that are respectively one of very dark color and the other of very clear color.
Alternatively the collectors (7) plane plate can have holes (22) throughout it to favor air flow or the collectors (7) can be realized with an honeycomb structure to increase the heat exchange surface.
Collectors, with the help of an electrical engine (12) and a battery (13) rechargeable with a solar panel (23) can be oriented by rotation; the rotation movement along the elongation axis (8) allows to optimize the collector surface position to better absorb the solar radiation. The rotation movement along the elongation axis (8) of each collector (7) occurs through a tie point made of a support (9) for axis (8) and a gear (10) connected to an endless screw (11) moved by the engine (12).
The panel will be preferably placed along a south-exposed wall, with the collectors dark surface exposed to sun rays so to fully exploit solar radiation, heating the air that flows near or through the collectors.
The alternate exposure of the clear and dark collectors side and their inclination angle, allow to modulate the heat intake of the building. Through a manual control or an automatic solar clock control, the collectors (7) can rotate by 360° allowing to be used, in the case of window like installation , also as darkening or shady curtain as protection from excessive light, a typical condition when the sun is below 45°of the horizon.
Panel (1) can be used to produce also cold air. When installed to the Northern side of a building, with the clear surface of the collectors exposed, it acts as a heat barrier and favors the outflow of warm air from inside the building, facilitating the inflow of cooler air inside.
Panel (1), due to its air exchange capacity contributes to human beings health, favoring the establishment of an optimal environment counteracting mildews and bacteria formation, characteristics of humid and badly ventilated spaces.
Panel (1) installed on a wall helps to reduce visual impact, since the collectors placed with respect to the viewer position in such a way that they do not interfere excessively with the chromatic effect or the aesthetic of the building itself, when the panels (1) are mounted as a continuous facade, by means of expanded polyurethane spacers (15), of appropriate fixing system made of a cylinder with a hole (16) and relative hexagonal holed head screw (17), of seal (18), and of closure end plug (19), can be embedded each other to synchronize the collectors movement through one or few motorized panels (depending on the wall dimensions and taking into account the fact that one motorized panel can move up to three other ones without engine) in such a way that the wall can achieve a uniform color.
Serially mounted panels as a continuous facade help in reducing building heat loss, because of the panel internal air chamber, becoming an alternative insulation solution that counteract thermal dissipation and contributes to energy saving.
In a different construction approach of the present invention, the laminar collector can be manually rotated, in particular when they are installed on a window in place of a glass window. In this case a pulley (29) allowes to wrap/unwrap a rope (21) that moves the endless screw bar connected to the gear (10)
