Definitions
- the invention relates to an electrothermal solar module, consisting of a base plate, on the sun-facing side te photovoltaic elements are arranged and at the edge of a
- a thermally insulating housing which consists of the sun side of a translucent material. Used are plates made of glass or plastic, which leave most of the short-wave sun rays through, which then heat the fluid-carrying hollow body in the interior of the housing. With increasing temperature, it radiates a portion of the previously recorded energy again as long-wave heat radiation, which is only partially transmitted through the transparent cover, which is why the principle of operation of the solar collector is often referred to as "heat trap" or "greenhouse effect". So that as little heat as possible is lost through the remaining walls of the housing, it is advisable to insulate them, for which in the simplest case insulating material is used which has numerous air inclusions up to insulating layers which are a vacuum.
- Suitable energy converters are heat exchangers in which the liquid flows out of the solar collector through a coil which is arranged in a large storage tank for hot water and heats it in this way. Even easier are flowed through by the liquid radiator for heating of interiors.
- photovoltaics is an economically viable alternative.
- plates of semiconducting material - z For example, silicon - incident photons generate electrons and "holes" that are separated in the electric field of the space charge zone of the P-n junction When the two electrodes of such a solar cell via an electrical
- a direct current has formed and, according to the current state of the art, a direct current can generate an alternating current via an "inverter" which can be fed into the electrical supply network and in this way can be easily transported to distant points of consumption.
- a principal advantage of electrical energy is that it can be transported with great efficiency over long distances and processed with equally high efficiency.
- One disadvantage is that it can only be stored directly with great effort.
- the supply of electrical energy is one of the basic needs of everyday life. From the above consideration it follows that both thermal energy and electrical energy is needed at the same time, for. For example, for the supply of residential and working buildings and that for their extraction from solar energy currently also different, efficient processes are known.
- a major disadvantage of all previously known energy converters, however, is that they generate either electrical or thermal energy.
- the invention has set itself the task of developing a solar module that emits both thermal and electrical energy and works with the highest possible efficiency, but is still very simple and can rely on existing and proven components. Parts of the solar module should be usable for photovoltaic as well as for solar thermal energy.
- the invention proposes an electrothermal solar module, in which the frame is a U-shaped profile, the open side facing the sun and which is covered with a translucent transparenzenzplatte and through the interior of which at least one hollow profile extends, which of a liquid can be flowed through.
- the photovoltaic part of a solar module according to the invention consists of standard solar cells produced on the
- the frame required for the mechanical stability of the photovoltaic structure is anyway used, by designing the frame as a sun-open, U-shaped profile whose open side is covered by a transparent transparency plate. In the resulting interior at least one hollow profile, which is flowed through by a liquid runs.
- This structure corresponds to the current state of the art for solar collectors:
- the short-wave radiation of the sun penetrates the transparency plate and heats the hollow profile with the liquid contained therein.
- the hollow profile radiates heat which, however, due to its long waves, is for the most part prevented by the transparency plate from escaping out of the interior again.
- a thermal insulation of the remaining walls improves the efficiency.
- the liquid-flow hollow profile is in the simplest case a tube or a hose.
- rib profiles on the outer surface are advantageous.
- flow channels are formed in the inner wall, which enlarge the effective inner surface.
- the next step in a meaningful improvement is to make the flow channels spiral, so that the liquid gets a twist, which forms turbulence, which significantly improves the heat transfer.
- Hollow profile is adjacent.
- the less heated liquid is heated with very good efficiency, surplus thermal energy from the adjacent, already strongly heated hollow profile can be delivered to the cooler hollow profile, whereby overheating is avoided and an approximately uniform temperature level is achieved along the frame.
- the invention proposes various embodiments.
- the contact surface between the frame and base plate is dimensioned larger than is necessary for purely mechanical fastening of the base plate and the discharge of the loads.
- the area for forwarding the thermal energy from the base plate into the frame is removed.
- the contact surface can be acted upon with a thermal paste, so that forms a perfect, thermal transition even when not completely touching contact surface and base plate. This configuration makes sense if the temperature of the base plate is higher than the temperature of the frame.
- the baseplate with additional piping through which the liquid flows. It is possible to form these pipelines within the base plate or to apply them on an outer surface. Since the sun-facing side should be reasonably reserved for the photovoltaic elements, the invention prefers the attachment of these additional pipes on the back. Welding, gluing, soldering, clamping or grooving are suggested for the connection between piping and base plate. Other, thermally well conductive compounds are also suitable.
- a solar module which consists of numerous, juxtaposed photovoltaic elements 2, which are mounted on the base plate 1.
- the frame 3 which z. B. on the outside integrally formed fastening eyes 32 for screwing the complete solar module on the roof.
- the frame 3 is a U-shaped profile whose open side is covered by the transparency plate 4. In the interior of this profile run in the drawing two hollow sections. 5
- FIG. 2 shows the cross section through the frame profile and the base plate 1 fastened thereto.
- the profile of the frame 3 has on its outer side fastening eyes 32, by means of which the solar module can be attached, for. B. can be screwed onto a roof surface.
- the contact surface 31 can be seen on softer the base plate 1 rests and z. B. is secured by a screw.
- the profile of the frame 3 is designed approximately U-shaped and is closed at the top by the transparency plate 4. This creates a closed interior, in which run in this example, two hollow sections 5.
- These hollow profiles have on their outer side the rib profile 51 in order to increase the effective surface and thereby improve the heat transfer.
- the flow channels 52 are formed in the inner wall. If these flow channels 52 are spirally wound around the longitudinal axis of the hollow profile, a spin arises in the liquid 6, which leads to turbulences, which mix the liquid 6, so that all particles of the liquid come into direct contact with the wall of the hollow profile 5 and to be heated better.
- Hollow section 5 should have a direction opposite to the adjacent hollow profile 5 flow direction.
- a pipe 7 is shown in Figure 2, which rests on the underside of the base plate 1 and is held there with the clamp 71.
- the pipeline 71 has such a profile that it contacts the base plate 1 over the entire area with a large proportion of its outer surface, so that a good heat transfer between the base plate 1 and the pipeline 7 is ensured.
- Figure 2 it is understood that a thermally even better connection is achieved by the integration of the pipe 7 directly into the material of the base plate 1.
