Description

Es sind Frühbeetheizungen bekannt, beiThere are cold frame heaters known at

denen der Boden indirekt durch heißes Wasser, Heizgase oder Dämpfe, die durch im Boden verlegte Rohre oder Kanäle strömen oder gesaugt werden, geheizt wird.those of the floor indirectly through hot water, heating gases or vapors through im Pipes or ducts laid in the ground flow or are sucked in, heated.

Es sind weiter Frühbeetheizungen bekannt, bei denen die Luft im Frühbeet durch in offenen Kanälen fließendes heißes Wasser oder durch direkte Ausstrahlung eines Ofens und seines die Heizgase ins Freie abführenden Abzugrohres erwärmt wird.There are also known cold frame heaters in which the air in the cold frame through in open Channels running hot water or by direct radiation of a stove and its flue pipe discharging the hot gases into the open is heated.

Es sind ferner Heizrohre bekannt, deren Mantelflächen im Querschnitt als Kreissegmente ausgebildet sind. Hierdurch soll erreicht werden, daß die senkrecht zur Fläche austretenden Wärmestrahlen sich in einer Linie vereinigen. Um den bei diesen Heizrohren angestrebten Zweck, eine Erwärmung der diese Linie timgebenden Luftsäule und damit eine ununterbrochene Luftbewegung in Längsrichtung der Rohre zu erreichen, müßten mehrere Heizrohre senkrecht nebeneinander mit genügender Länge angeordnet werden, was bei einem Frühbeet aber kaum möglich wäre.There are also known heating pipes whose lateral surfaces in cross-section as circular segments are trained. This is intended to ensure that the heat rays emerging perpendicular to the surface merge into one Unite line. In order to achieve the purpose aimed at with these heating pipes, namely heating the column of air that timed this line and thus an uninterrupted movement of air in To achieve the longitudinal direction of the pipes, several heating pipes would have to be perpendicular to each other be arranged with sufficient length, which would hardly be possible with a cold frame.

Demgegenüber zeichnet sich die Erfindung durch die Möglichkeit einfachster Ausführung und Anordnung aus. Ihr wesentlich unterscheidendes Merkmal besteht aber darin, daß das Wasser ohne Trennung im Gegenstrom zn- und abfließt, wobei die Wasserbewegung allein durch den Wärmeaustausch bewirkt wird. ΙΊη dies zu erreichen, ist nur eine schwach eingezogene Querschnittsform notwendig gegenüber den im Querschnitt genaue Kreissegmente bildenden Flächen der bekannten Heizrohre.In contrast, the invention is characterized by the possibility of the simplest implementation and arrangement. Their essential distinguishing feature, however, is that the water flows in and out in countercurrent without separation, with the movement of the water caused solely by the heat exchange. To achieve this is only one thing slightly indented cross-sectional shape necessary compared to the exact cross-section Circle segments forming surfaces of the known heating pipes.

Gegenstand der Erfindung ist eine Warmwasserheizung für Frühbeete, die aus einem an sich schon bekannten beliebig beheizten Ofen mit ihn umgebendem Wassermantel und einem die Wärme abgebenden Heizelement besteht. Das Heizelement ist ein Rohr mit länglicher, in der Mitte der Längsseiten eingezogener Querschnittsform.The subject of the invention is a hot water heater for cold frames, which consists of an already known, arbitrarily heated oven with a surrounding water jacket and a heating element that emits the heat. The heating element is a tube with an elongated cross-sectional shape drawn in in the middle of the long sides.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.The subject matter of the invention is shown in the drawing, for example.

Der Ofen# heizt das in dem Wassermantelraum b enthaltene Wasser. Dieser Raum b ist über die Leitungen c und d mit dem Heizelemente verbunden. In dem Heizelemente strömt das Wasser infolge des Wärmeaustausches in der durch Pfeile bezeichneten Richtung. Das heiße Wasser tritt also von dem Mantelraum b durch das Rohr c in das Heizelement e ein, durchfließt es im Zulauf in der oberen und im Rücklauf, ohne daß eine Trennwand vorhanden ist, in der unteren Hälfte, um durch das Rohr d in den Mantelraum b zu neuem Kreislauf zurückzukehren.The furnace # heats the water contained in the water jacket space b. This space b is connected to the heating elements via lines c and d. As a result of the heat exchange, the water flows in the heating element in the direction indicated by arrows. The hot water thus enters from the jacket space b through the pipe c in the heating element e , it flows through the inlet in the upper and in the return, without a partition , in the lower half to go through the pipe d in the Shell space b to return to the new cycle.

Zum Ausgleich etwa entstehenden Überdruckes erhält das Heizelemente in bekannter Weise ein Überlaufgefäß/. In ebenfalls bekannter Weise werden die nun durch den Wassermantelraum b erheblich gekühlten Abgase des Ofens α ohne Gefahr für die Pflanzen mittels des Abzugrohres g durch das Frühbeet ins Freie geführt.To compensate for any excess pressure that may arise, the heating element is provided with an overflow vessel / in a known manner. In a likewise known manner the now b considerably cooled by the water jacket space of the furnace exhaust gases are α without danger to the plants by means of the flue g guided to the outside by the cold frame.
