Abstract

The collector has a concentrating lens which is formed of two layers (1, 2) of a material transparent to light which are curved in opposite directions to each other so as to form a space between them. Water flows through this space by means of connections (3) at its ends. The transparent container with water in it, forms a longitudinal concentrating lens which brings incident radiation to a focus along a line a small distance below the lens. A tube (4) with a blackened surface is arranged along this line and domestic hot water (6) to be heated is pumped through it. The construction gives an effective way of concentrating solar radiation to give a high temp. for heating the water.

Description

Sonnenenergiekollektor mit Lichtbündelung Solar energy collector with bundling of light

auf einer Trennlinie Aufgabenstellung Gattung, Gegenstand, Gebiet Die im Folgenden beschriebene Erfindung befaßt sich mit der Umsetzung von Sonnenenergie in wirtschaftlich nutzbare Warme. on a dividing line task type, subject, area The invention described below deals with the conversion of solar energy in economically usable heat.

Die Lösung ermtglicht eine preiswerte und trotzdem bezviglich erreichbarer Temperaturen und versniezener Verlusten effektive Kollektorkonstruktion, deren Vasen darin besteht, das Sonnenlicht mittels einer preiswert herzustellenden Linsenausführung auf einer Brennlinie zu bündeln und damit die Aufheizung des Wärmetransportmediums im kontinuierlichen Prozeß wie in einem Durchlauferhitzer zu erreichen.The solution enables an inexpensive and nevertheless more accessible Temperatures and sneezed losses effective collector construction, their vases consists in the sunlight by means of an inexpensive to manufacture lens design to focus on a focal line and thus the heating of the heat transport medium in a continuous process like in a water heater.

mäntel und Nachteile die beseitigt werden sollen.coats and disadvantages to be eliminated.

Zur Speicherung von Wärme oder für viele technische Ånwendungsfälle ist es vorzuziehen ein Wärmetransportmedium mit höherer Temperatur zur Verfügung zu haben. Mit Sonnenkollektoren ohne Bündelung des Lichtes lassen sich sinnvoll keine höheren Temperaturen erzielen. Bisher bekannt gewordene Methoden der Licht bündelung wie Vollglaslinsen oder Hohlspiegel erfordern einen hohen Bertigungs- und Isolationsaufwand zur Vermeidung von Verlusten.For storing heat or for many technical applications it is preferable to use a heat transport medium with a higher temperature to have. Using solar panels without focusing the light can make sense do not achieve higher temperatures. So far known methods of light bundling such as full glass lenses or concave mirrors require a high level of operation and isolation effort to avoid losses.

Lösung Merkmale Es wird das seit langem bekannte Prinzip der Schusterkugel (d.h. eine mit Wasser gefüllte Glaskugel, die aufgrund der Lichtbrechung des Glases und des Wassers das von einer Kerze kommende Licht so bündelt, daß ein Lichtfleck mit höherer Lichtstärke entsteht, wodurch dem Benutzer ein besseres Sehen bei feinen Arbeiten ermöglicht wird) dahingehend abgewandelt, daß das Licht durch eine mit einem lichtdurchlässigen Medium z.B. Wasser gefüllte Säule aus lichtdurchlässigem Material z.B. Glas, deren Grundfläche die Form einer Sainmellinse hat, auf einer Trennlinie gebündelt wird. In dieser Brennlinie kann zum Beispiel mittels eines entsprechend ausgebildeten Rohres die Energie auf ein zum Wärmetransport geeignetes Medium z.n.Solution Features It becomes the long known principle of the shoemaker's ball (i.e. a glass ball filled with water, which due to the Refraction of the glass and the water bundles the light coming from a candle in such a way that a Light spot with higher light intensity is created, which gives the user better vision is made possible in fine work) so that the light through a column filled with a light-permeable medium, e.g. water, made of light-permeable Material e.g. glass, the base of which has the shape of a Sainmell lens, on a Dividing line is bundled. In this focal line, for example, by means of a appropriately designed tube transfers the energy to a suitable for heat transport Medium z.n.

Wasser nach der Art eines Durchlauferhitzers übergehen. Desweiteren besteht die Möglichkeit das Wärmetransportinedium zuvor durch die Sagnellinsensäule fließen zu lassen. Dort wird es durch die unvermeidlichen Lichtverluste schon voraufgeheizt bevor es der eigentlichen Erhitzungsstrecke zugeführt wird.Pass over water in the manner of a water heater. Further there is the possibility of the heat transport medium beforehand through the Sagnell lens column to let flow. There it is preheated by the inevitable loss of light before it is fed to the actual heating section.

Wirkung weise Die Linsensäule wird durch zwei durchsichtige Wandungen (1 u. 2) gebildet, deren Formgebung im Querschnitt der einer Sammellinse entspricht. Diese Linsensäule ist mit einem durchsichtigen Medium (3) z.B. Wasser gefüllt bzw. wird von diesem durchflossen. Gemäß den Brechungsindizes des Materials der Säulenwandungen (1 u. 2) und des Mediums (3) innerhalb der Säule wird das ankommende, parallele sonnenlicht auf einer Brennlinie gebündelt. Die Lichtkonzentration ist mit einer Energiekonzentration gleichzusetzen. Die Höhe der hier erreichbaren Energiekonzentration hängt von der wirksamen Breite der Linsensäule und von ihrer Fertigungsgenauigkeit ab. In dieser Brennlinie ist ein Element (4) angeordnet, z.B. ein Rohr durch das die Energie auf ein Wärmetransportmedium (6) übergeht. Dieses Medium kann identisch sein mit dem, welches durch die Linsensäule fließt. Es besteht die Möglichkeit viele Linsensäulen hintereinanderzuschalten, sie durchfließen zu lassen, d.h. das Medium kann die unvermeidlichen Lichtverluste in Form von Wärme aufnehmen, und dann das medium den Energieaufnahmeelementen zuzuführen wo es vollends aufgeheizt wird und anschlißend dem Verwendungszweck zufließt.Effect wise The lens column is made up of two transparent walls (1 and 2) formed, the shape of which corresponds in cross-section to that of a converging lens. This lens column is filled with a transparent medium (3) e.g. water or is traversed by this. According to the refractive indices of the material of the column walls (1 and 2) and the medium (3) within the column becomes the incoming, parallel one sunlight focused on a focal line. The light concentration is with one To equate energy concentration. The level of the energy concentration that can be achieved here depends on the effective width of the lens column and on its manufacturing accuracy away. An element (4) is arranged in this focal line, e.g. a pipe through the the energy is transferred to a heat transport medium (6). This medium can be identical be with the one that flows through the lens column. There is a lot of possibility To connect lens columns one behind the other, to let them flow through, i.e. the medium can absorb the inevitable loss of light in the form of heat, and then that medium to supply the energy absorption elements where it completely heated up and then flows to the intended use.
