Definitions
- the present invention is based on a solar collector module consisting of a hollow body which is at least partially transparent and which contains an absorption layer, wherein the absorption layer is designed to convert radiation from the environment into heat, and wherein a flowing through the hollow body fluidic medium is provided as a heat transfer medium.
- Thermal solar collectors are used to convert the light energy of the sun into heat, which in turn is delivered to a heat transfer medium flowing through the solar collector.
- a thermosyphon principle In the heating of the heat carrier and in the transfer of heat energy into a memory, as described in DE 199 08 014, often made use of the so-called thermosyphon principle.
- the different density of the heat carrier such as e.g. Water at different temperatures, used to power the water cycle. Heated water rises due to its lower density in the solar collector upwards, then flows back through the heat exchanger in the storage tanks and after the cooling and downward flow back into the collector. It is thus a gravity circulation.
- a solar collector which contains a water / glycol mixture as the heat transfer medium.
- the water / glycol mixture is located in a heat exchanger, where it can be heated by radiant energy.
- the water / glycol mixture in the heat exchanger can also be heated by the passing ambient air when the temperature in the heat exchanger is lower than the air temperature. Is the temperature of the
- a disadvantage of the solar collectors described above is the use of a liquid heat transfer medium.
- water must be protected against freezing by an electric heater or by adding antifreeze. Also may be due to regionally different water quality damage potential for a solar system.
- thermal aging processes can also take place, which necessitate expensive maintenance of a solar system.
- Problems can also occur with little or no heat loss from the solar collector (stagnation).
- Liquid media such as e.g. Water, then can partially go into the gaseous state. This requires the installation of a protective device against overheating and thus leads to a more complex structure of the solar collector.
- DE 195 17 471 describes a solar collector with integrated storage for hot water preparation and for heating air.
- the memory is constructed so that initially heated by the solar energy of the water tank. The heating of the air is done by a running in the hot water tank heat exchanger tube.
- a disadvantage of this arrangement is that first the hot water tank must be heated before the heating of the air can take place in the heat exchanger tube.
- the memory module is constructed so that it can not be connected seamlessly with other memory modules to a solar collector arrangement, but must be connected via pipes with other memory modules to a solar system. A solar system comprising many such memory modules thus has an increased space requirement due to the required connecting pipes.
- the present invention has the object to provide a comparison with the prior art improved solar collector, which is simple and robust. Furthermore, the problem of frost protection, aging and the Overheating of liquid media can be avoided. Furthermore, the structure of the solar collector should allow a compact arrangement within a solar system.
- the solar collector module comprises a hollow body which is at least partially transparent and which contains an absorption layer which is designed to convert radiation from the environment into heat, wherein a fluid medium flowing through the hollow body is provided as a heat carrier and the hollow body further has an inlet opening and an outlet opening for the fluidic heat carrier and is designed such that the fluidic heat carrier flows directly over the absorption layer and is thereby heated.
- An advantageous embodiment of the invention provides in particular the use of a gaseous heat carrier, which flows directly over the absorption layer. This avoids problems associated with the use of liquid heat carriers, such as thermal aging, frost protection or overheating. Due to the direct contact of the gaseous heat carrier whose rapid heating is also possible.

- the intermediate space between the first and the second cylindrical structure is closed in a gas-tight or vacuum-tight manner.
- a storage container for liquid media is arranged and the absorption layer is arranged on the surface of the storage container.
- the hollow body consists of a thermally insulated, channel-shaped chamber and a flat thermosiphon arrangement containing the absorption layer, wherein the thermally insulated, channel-shaped chamber and the two-dimensional thermosyphon arrangement are connected to one another in that the fluidic heat carrier flows from the chamber into the thermosiphon arrangement, is heated and flows back into the chamber. It is advantageous that a larger surface is available for the heating of the fluidic heat carrier by the flat Thermosiphon- arrangement. Regardless of the design of the thermally insulated, channel-shaped chamber, the thermosyphon arrangement can be optimized for the purpose of heating the fluidic heat carrier. This leads to higher performance and efficiency of the solar collector module.
- the at least partially transparent hollow body consists of a chamber and a flat thermosyphon arrangement containing the absorption layer, which are interconnected so that the gaseous heat carrier directly into the thermosyphon through a decentralized opening -Inowski flows, is heated and flows into the chamber.
- the advantage of this embodiment is that only the heated gaseous heat transfer medium into the thermally insulated, channel-shaped chamber passes and thus more efficient heating of the gaseous heat carrier and a storage container is made possible.

- gravity circulation of the heat carrier can take place due to the differences in density of the cold and heated fluidic heat carrier. This is advantageous because it can be dispensed with, for example, the installation of a pump or a fan for generating a heat transfer flow.
- two or more solar collector modules according to one of the preceding claims can be arranged in series in such a way that a channel is formed by the hollow body through which the fluidic heat carrier flows.
