Abstract

The solar collector includes thermo-electric units, e.g. thermogenerators (4), between absorbtion surfaces (3) and built into a heatable medium (5). The collector surfaces convert sun rays (1) into heat for e.g. domestic heating using thermo-generator components installed between the absorption surface and the medium to be warmed. The thermoelectric generators may be used to convert a part of the warm energy flow into electrical energy using the Seebeck effect. To increase the internal working temperature an isolated housing with a transparent cover (2) is used. The housing is evacuated to minimise heat loss to the surroundings.

Description

Derzeit existieren zwei verschiedene Prinzipien zur Nutzung der Energie der solaren Einstrahlung. Zum einen kann mittels photovoltaischer Solarzellen das Licht der Solarstrahlung durch geeignete Halbleiter­ bauelemente in elektrische Energie umgewandelt werden. Eine völlig andere Form der Solarenergienutzung besteht darin, mittels sog. thermischer Kollektoren ihre Energie einer thermischen Verwendung zuzuführen. Diese thermischen Kollektoren bestehen aus einer Absorberfläche, die die auftreffende Solarstrahlung in Wärme umwandelt. Diese Wärme wird über ein Medium, i.a. eine Flüssigkeit, die kalt zugeleitet wird und die Wärme des Absorbers aufnimmt, abgeführt und der Nutzung (Brauchwassererwärmung, Raumheizung, Prozeßwärme) zugänglich gemacht.There are currently two different principles for using energy solar radiation. Firstly, by means of photovoltaic Solar cells the light of solar radiation through suitable semiconductors components are converted into electrical energy. A totally another form of using solar energy is by means of so-called thermal collectors use their energy for thermal use feed. These thermal collectors consist of one Absorber surface that converts the incident solar radiation into heat. This heat is transferred through a medium, i.a. a liquid that is cold is supplied and absorbs the heat of the absorber, and use (domestic water heating, space heating, process heat) made accessible.

Mit den bestehenden Techniken kann also entweder eine thermische Nutzung der Solarenergie erfolgen oder die Erzeugung elektrischer Energie.With the existing techniques, either a thermal Use solar energy or generate electrical Energy.

Die vorliegende Erfindung vermeidet diesen Zielkonflikt und erlaubt sowohl die thermische Nutzung als auch die Erzeugung von elektrischer Energie. Es handelt sich bei der Erfindung um eine Weiterentwicklung der thermischen Kollektoren durch den zusätzlichen Einbau thermo­ elektrischer Energiewandler (sog. Thermogeneratoren). Diese sind bereits seit vielen Jahren bekannt (siehe z. B. Zeitschrift "Meerestechnik" 3 (1972), Nr. 2, S. 59ff) und wandeln auf der physikalischen Grundlage des Seebeck-Effektes einen Teil der durch sie hindurchfließenden Wärmeenergie in elektrische Energie um. Diese Thermogeneratoren (4) werden zwischen den die Solarstrahlung (1) in Wärme umwandelnden Absorber (3) und das die Wärmeenergie abführende Medium (5) (in der Abbildung eine Flüssigkeit in Röhren) plaziert. Durch entsprechende Konstruktion wird erreicht, daß die Wärme ausschließlich über die Thermogeneratoren vom Absorber zum zu erwärmenden Medium gelangt. Um eine hohe Effizienz sowohl der thermischen als auch der elektrischen Nutzung zu erzielen wird die gesamte Einheit in einem thermisch isolierten und mit einer transparenten Abdeckung (2) versehenen Gehäuse untergebracht, das zur weiteren Steigerung des Wirkungsgrades evakuiert sein sollte.The present invention avoids this conflict of objectives and allows both thermal use and the generation of electrical energy. The invention is a further development of the thermal collectors through the additional installation of thermo-electric energy converters (so-called thermogenerators). These have been known for many years (see, for example, magazine "Meerestechnik" 3 (1972), No. 2, p. 59ff) and convert part of the thermal energy flowing through them into electrical energy based on the physical basis of the Seebeck effect around. These thermogenerators ( 4 ) are placed between the absorber ( 3 ) which converts the solar radiation ( 1 ) into heat and the medium ( 5 ) which dissipates the heat energy (in the figure a liquid in tubes). Appropriate construction ensures that the heat only reaches the medium to be heated from the absorber via the thermal generators. In order to achieve high efficiency of both thermal and electrical use, the entire unit is housed in a thermally insulated housing with a transparent cover ( 2 ), which should be evacuated to further increase the efficiency.
