Abstract

The absorber is constructed from two flat rectangular plates (1). Each plate is pressed out to have a recess (5) which runs in the form of a coil across the whole of the plate. The two plates are then placed on top of each other with the recesses facing each other and are joined along the flat parts which touch. The joining can be done by contact welding, arc welding, soldering or by the use of adhesives. In all cases the result is a flat plate of double thickness with a closed coil within it. Transition pieces (4) are joined to the ends of the coil and the absorber is connected to the flow and return pipes (3) by means of these transition pieces.

Description

Zusatzpatentbeschreibung: 1'Solar-Kollektorplatte" Die erfindung betrifft eine Solar-Kollektorplatte zur Umwandlung der Sonnenstrahlungsenergie in Wärmeenergie (z.B. Warmwassererzeugung). Hierbei wird die Sonnenstrahlungsenergie durch die spektralselektive Solar-Kollektorplatte absorbiert. Die Solar-Kollektorplatte besitzt ein Rohrsystem, durch das ein flüssiges Medium geleitet wird. Dieses flüssige Medium wird beim Durchgang durch die Kollektorplatte erhitzt.Additional patent description: 1'Solar collector plate "The invention concerns a solar collector plate for converting solar radiation energy into thermal energy (e.g. hot water generation). Here the solar radiation energy is through the spectrally selective Solar collector plate absorbed. The solar collector plate has a pipe system, through which a liquid medium is passed. This liquid medium is in the passage heated by the collector plate.

In der Patentanmeldung P 25 23 479.1 vom 20.Mai 1975 'Solar-Kollektor" Anmelder: Dr.-Ing. Peter Marx, Berlin wird die Problematik der Nutzbarmachung der Sonnenenergie mittels geeigneter Solar-Kollektoren ausführlich beschrieben.In the patent application P 25 23 479.1 of May 20, 1975 'Solar collector " Applicant: Dr.-Ing. Peter Marx, Berlin will address the problem of making the Solar energy by means of suitable solar collectors described in detail.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die in der o.g. Patentanmeldung genannte doppelwandige, durch mäanderförmig angeordnete Zwischenstege verbundene Kollektorplatte durch eine verbesserte Konstruktion zu ersetzen, die an die Erfordernisse einer Großserienproduktion besser angepaßt ist.The present invention is based on the object in the The above-mentioned patent application is double-walled, with intermediate webs arranged in a meandering manner to replace connected collector plate with an improved construction that is better adapted to the requirements of large-scale production.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Solar-Kollektorplatte, die gekennzeichnet ist durch zwei Platten aus einem Material mit guter Wärmeleitfähigkeit, die miteinander mittels geeigneter fügetechnischer Verfahren verbunden sind. Die beiden Platten weisen symmetrisch angeordnete,mäanderförmig verlaufende Vertiefungen (Sicken) auf, wodurch ein druck- und temperaturfestes Rohrsystem zur Aufnahme des Wärmetransportmittels entsteht.This object is achieved according to the invention by a solar collector plate, which is characterized by two plates made of a material with good thermal conductivity, which are connected to one another by means of suitable joining processes. the Both plates have symmetrically arranged, meandering depressions (Beads), creating a pressure and temperature-resistant pipe system to accommodate the Heat transport medium arises.

Ein Ausführungsbeispiel ist in der beiliegenden Zeichnung dargestellt und wird im folgenden näher beschrieben.An exemplary embodiment is shown in the accompanying drawing and is described in more detail below.

Fig. 1 zeigt die Draufsicht der Solar-Kollektorplatte. Die obere Platte 1 besitzt Rechteck-Format, die mäanderförmig verlaufenden Sicken werden in geeigneter Geometrie angeordnet. Die Ein- und Ausläufe 3 sind über ein passendes Ubergangsstück 4 mit dem Rohrsystem 5 der Solar-Kollektorplatte verbunden.Fig. 1 shows the top view of the solar collector plate. The top plate 1 has a rectangular format, the meandering beads are more suitable Geometry arranged. The inlets and outlets 3 are via a suitable transition piece 4 connected to the pipe system 5 of the solar collector plate.

Fig. 2 zeigt die Solar-Rollektorplatte im Schnitts Die obere Platte 1 ist mit der unteren Platte 2 an den Berührflächen geeignet verbunden (z*B Rollennahtschweißen, Explosionsschweißen, Loten, Kleben etc.) t so daß ein druck- und temperaturfestes Rohrsystem 6 entsteht.Fig. 2 shows the solar roller gate plate in section. The top plate 1 is suitably connected to the lower plate 2 at the contact surfaces (e.g. roller seam welding, Explosion welding, soldering, gluing, etc.) t so that a pressure and temperature-resistant Pipe system 6 is created.

Der entsc'ei3ende Vorteil dieser Solar-'xollektorplatten-Konstruktion besteht darin, daß in drei schnellen Produktionsschritten die komplette Solar-Kollektorplatte gefertigt werden kann: 1. Prägung der Platte 1 , 2. Prßgung der Platte 2 , 3. Verbindung der beiden Platten.The key advantage of this solar collector plate construction consists in the fact that in three quick production steps the complete solar collector plate can be manufactured: 1. Embossing of plate 1, 2. Embossing of plate 2, 3. connection of the two plates.
