Abstract
Description
Vereinfachter Aufbau von verspiegelten Vacuum - KollektorenSimplified construction of mirrored vacuum collectors
Als hochwirksame Vacuum - Kollektoren sind z.B0 die Röhren der Firma Philips bekannt. ~Rnn Nachteil der Konstruktion besteht in der geringen wirksamen Fläche pro Röhre, so daR viele Röhren zusammengeschlossen werden, um einen Kollektor 7von 1 - ? qm fläche zu erhalten. Dabei müssen auch eine größere Zahl von Spiegels echten wie auch halbdurchlässigen selektiven, erstellt werden0 Deshalb wird erfindungsgemäß vorgescIagen, Vacuum - Kollektoren dadurch zu erstellen, daß die unteren Teile bzwo auch die oberen Teile zu einem gemeinsamen Bauteil zusammengefaßt werden. So entstehen nach außen gewölbte Glasflächen, von denen je zwei aufeinandergeklebt eine Anzahl von den üblichen Glasröhren ersetzen werden Natürlich wird man die Wölbungen so erstellen, daß man die eigentlichen Absorptionsflächen nun als Schlange gewullden durch die Fläche führt; damit entfallen mehrere Rohranschlasse, wie sie ja bei der üblichen Bauart nötig sind, eben pr@ Röhre zweiO Damit sind auch die Spiegel der sonst einzelnen Röhren in einem Bauteil zusammengefaßt und in einem Arbeitsgang zu erstellen, Die sonst üblichen Einschmelzungen der Röhrenenden zur Verjüngung entfallen auch im Wesentlichen durch eine entsprechende Konstruktive Ausleglmg der Gesamt-Scheiben, die nun einfach aufeinander geklebt werden. Das kann mit glasklarem Kunststoff an den erhabenen Stellen geschehen, der über Walzen aufgetragen wird0 Möglich ist aber auch die Einbringung einer dritten, aber ebenen Scheibe zwischen die beiden anderen gewölbten Scheiben, denn sie kann als Halterung für die A. - Schlange dienen und alternativ die selektive Beschichtung tragen und auch das Aufeinanderfügen der beiden gewölbten Scheiben erleichtern, da so die spitzen Kanten nicht so leicht von einander abgleiten,The company's tubes, for example, are highly effective vacuum collectors Known to Philips. ~ Rnn disadvantage of the construction consists in the low effective Area per tube, so that many tubes are connected to one collector 7of 1 -? to get sqm of space. There must also be a larger number of mirrors real as well as semi-permeable selective, are created0 Therefore, according to the invention proposed to create vacuum collectors that the lower parts or the upper parts can also be combined to form a common component. So arise outwardly curved glass surfaces, a number of which are glued on top of each other Of course you will replace the bulges that way create that the actual absorption surfaces are now wound as a snake leads through the surface; this eliminates the need for several pipe connections, as is the case with the usual design are necessary, just pr @ tube twoO This means that the mirrors are also the otherwise individual tubes combined in one component and in one operation to create, the otherwise usual fusing of the tube ends for tapering are also essentially omitted due to a corresponding structural design of the Total panes, which are now simply glued to one another. That can be done with crystal clear Plastic done in the raised areas, which is applied via rollers0 However, it is also possible to introduce a third, but flat, pane between the other two domed discs, because they can be used as a holder for the A.- Serve snake and alternatively wear the selective coating and also the one on top of the other of the two curved panes make the sharp edges less easy slide from each other,
