Description

Elektrischer Durchlauferhitzer Die Erfindung betrifft einen elektrischen Durchlauferhitzer zum Erwärmen flüssiger Medien wie Wasser, öl od.derglO Derartige Durchlauferhitzer bestehen im wesentlichen aus einem Durchlaufrohr und einem, mit diesem verbundenen Heizkörper, wobei es besonders wichtig ist, daß zwischen diesen Teilen eine möglichst gut die Wärme leitende Verbindung besteht, die meist durch Löten oder Schweißen erreicht werden mußO Diese Herstellungsverfahren sind jedoch ziemlich aufwendig, so daß man schon bald nach Konstruktionen suchte, die preiswertere Fertigungen ermöglichen. Electric instantaneous water heater The invention relates to an electric heater Flow heater for heating liquid media such as water, oil or the like Flow heaters essentially consist of a flow pipe and a, with this connected radiator, it is particularly important that between these Share the best possible heat-conducting connection, which is usually through Soldering or welding must be achieved. However, these manufacturing processes are quite expensive, so that soon they were looking for constructions that were cheaper Enable manufacturing.

So beschreibt die D-OS 25 37 769 einen Durchlauferhitzer, der von einem Stranggußteil aus Aluminium od.dergl. ausgeht, der als solcher schon den Durchlaufkanal enthält und außerdem eine oder mehrere, parallel zu diesem Kanal verlaufende Nuten aufweist, in die eine Heizleiterwendel mittels einer Isoliermasse eingebettet ist.Thus, the D-OS 25 37 769 describes a water heater that of a continuous casting made of aluminum or the like. goes out, which as such already has the flow channel contains and also one or more, parallel to this channel extending grooves has, in which a heating conductor coil is embedded by means of an insulating compound.

Bei diesem Durchlauferhitzer entfallen aufwendige Schweiß-oder Lötarbeiten, doch ist das Montieren der Heizwendel unmittelbar in den Nuten noch mit großem Arbeitsaufwand verbunden.With this water heater, there is no need for complex welding or soldering work, but mounting the heating coil directly in the grooves still requires a great deal of work tied together.

Darüberhinaus geht bei derartigen Durchlauferhitzern allgemein das Bestreben dahin, niedrige Oberflächenbelastungen bei dem zu erwärmenden Medium zu erreichen, um auf diese W4eise, beispielsweise bei Wasser das Verkalken der Durchlaufkanäle möglichst weitgehend zu reduzieren.In addition, this is generally the case with such instantaneous water heaters the Endeavor to have low surface loads on the medium to be heated in this way, for example in the case of water, the calcification of the flow channels to reduce as much as possible.

Auch bei der erwärmung anderer flüssiger medien muß diese thermiscile Oberflächenbelastung möglichst gering gehalten werden, so zum Beispiel beim Erwärmen von schwerem Heizöl. Bier kann eine zu hohe Belastung zum Vercracken des Öls an dessen Oberfläche führen, Aufgabe der vorliegenden Erfindung ist CS einen burchlauferhitzer zu schaffen, der als Massenartikel nicht nur urc-lsgünstig herstellbar ist, sondern auch, ohne nachteilige Beein flussung seiner thermischen Leistung als solcher, eine niedrige thermische Oberflächenbelastung für die zu erwarmenden Medien aufweist.This must also be used when heating other liquid media Surface load should be kept as low as possible, for example when heating of heavy fuel oil. Beer can put too much stress on the oil to crack its surface lead, the object of the present invention is CS a water heater to create, which as a mass-produced article can not only be produced very inexpensively, but also also, without adversely affecting its thermal performance as such, a has a low thermal surface load for the media to be heated.

Zu diesem Zweck wird erfindungsgemäß vorgeschlagen, den Durchlufkanal des Stranggußteils des Erhitzers aus einer oder mehreren Längsbohrungen mit großem Durchmesser zu bilden und als Heizeinrichtung einen oder mehrere, mit Aluminiummantel versehene Rohrheizkörper zu verwenden, der, bzwO die in entsprechende Längsnuten des Stranggußteils eingelegt und mit letzterem fest verpreßt sind0 Dieser neuartige Durchlauferhitzer ist sehr wirtschaftlich aus vorgefertigten eilen herzustellen und, infolge der damit erreichbaren niedrigen Oberflächenbelastung, auch sehr vielseitig verwendbar.For this purpose, the invention proposes the flow channel of the continuous casting of the heater from one or more longitudinal bores with large To form diameter and as a heating device one or more, with an aluminum jacket to use provided tubular heating elements, which or the in corresponding longitudinal grooves of the continuous casting are inserted and firmly pressed with the latter0 This new type The instantaneous water heater is very economical to manufacture from prefabricated parts and, due to the low surface load that can be achieved, also very versatile usable.

Der Gegenstand der Erfindung ist in der Zeichnung in mehreren Ausführungsbeispielen dargestellt. Es zeigen die Figuren 1 und 2 einen Erhitzer in einer Seitenansicht und im Schnitt in der Ebene II - Ii, Figuren 3 und 4 ein rusführungsbeispiel mit zwei hintereinandergeschalteten DurchZaufbohrungen, und Figuren 5 und 6 einen Durchlauferhitzer mit nur einem ohrheizkörper.The object of the invention is shown in the drawing in several exemplary embodiments shown. It show the Figures 1 and 2 show a heater in one Side view and in section in the plane II-Ii, Figures 3 and 4 an example of implementation with two through holes connected in series, and Figures 5 and 6 one Instantaneous water heater with only one ear heating element.

ber in den Figuren 1 und 2 dargestellte Durchlauferhitzer besteht aus einem Stranggußteil 1 mit einer Längsbohrung von großem i)iirchmesser und aus zwei parallel zur Bohrung 2 verlauf enden, um 1800 gegeneinander versetzten, mit Aluminiummantel 4 versehenen, verdicHBten Rohrheizkörpern 3, die in je einer entspr clAenden Längsnut 5 des Stranggußteils 1 eingelegt und mit let7terem verpreßt sind. Für das Zu- und Ableiten des Mediums sind an beiden Enden des Stranggußteils 1 Schlauchstutzen 6 vorgesehen, die in die Bohrungsenden eingepreßt sind. Die Fertigung dieses Durchlauferhitzers erfolgt so, daß man ein Stück von gewünschter Länge von einer Stranggußstange abteilt und dann zwei vorgefertigte, an beiden Enden angebogene Rohrheizkörper, die weitgehend automatisch herstellbar sind, in die Nuten des Stranggußteils einlegt und schließlich unter Anwendung hoher Drücke mit letzterem verpreßt0 Um einen einwandfreien Sitz der Schlauchstutzen 6 sicher zu stellen, wird die Bohrung 2 zweckmäßigerweise an beiden Enden auf. den Außendurchmesser der Schlauchstutzen 6 aufgebohrt. Wie die Zeichnung leicht erkennen läßt, wird mit der vorliegenden Anordnung von Durchlaufbohrung und Heizkörpern ein besonders gleichmäßiger Wärmeübergang vom Heizkörper zum Medium erreicht0 Eine sehr raumsparende und trotzdem leistungsfähige Ausführungsart zeigen die Figuren 3 und 4o Hier sind zwei großformatige Längsbohrungen 2 in Parallelanordnung im Stranggußteil 10 vorgesehen. Dic beiden Rohrheizkörper 3 liegen hier ebenfalls in Nuten 5, die zwischen den beiden Längsbohrungen angeordnet sind. Telährend in den rechtsseitigen Enden 14 dieser beiden Längsbohrungen 2 je ein Schlauchstutzen 7 für die Zu-und Ableitung des Mediums eingepreßt, oder eingeklebt sind, ist auf der linken Seite ein Teil des die beiden Längsbohrungen 2 trennenden Stegs 8 abgefräst und es sind die offenen Enden der beiden Bohrungen 2 mittels einer in diese eingepressten oder eingeklebten, gemeinsamen Kappe 9 verschlossen.About water heater shown in Figures 1 and 2 consists from a continuous casting 1 with a longitudinal bore of large i) diameter and from two running parallel to the bore 2 end, offset from one another by 1800, with Aluminum jacket 4 provided, thickened tubular heating elements 3, each in a corresponding The ends of the longitudinal groove 5 of the continuously cast part 1 are inserted and pressed with the latter. For the supply and discharge of the medium there are 1 hose connectors at both ends of the continuous casting 6 are provided, which are pressed into the bore ends. The manufacture of this water heater takes place in such a way that one divides a piece of the desired length from a continuously cast rod and then two prefabricated tubular heating elements bent at both ends, which are largely are automatically produced, inserted into the grooves of the continuous casting and finally using high pressures with the latter pressed0 to ensure a perfect fit To ensure the hose connector 6, the bore 2 is expediently at both ends. the outside diameter of the hose nozzle 6 is drilled open. As the Drawing can easily be seen, is with the present arrangement of through hole and radiators a particularly uniform heat transfer from the radiator to the medium achieved0 Show a very space-saving, yet powerful design Figures 3 and 4o Here are two large-format longitudinal bores 2 in a parallel arrangement provided in the continuous casting 10. The two tubular heating elements 3 are here Likewise in grooves 5 which are arranged between the two longitudinal bores. Teleholding in the right-hand ends 14 of these two longitudinal bores 2 each have a hose connector 7 pressed in or glued in for the supply and discharge of the medium is on the left side of a part of the web 8 separating the two longitudinal bores 2 is milled off and the open ends of the two bores 2 are pressed into them by means of a or glued-in, common cap 9 closed.

Mit dieser Anordnung erreicht man, daß am Ende der einen Bohrung das Medium in die andere Bohrung umgeleitet wird und so doppelt so lange der Erwärmung ausgesetzt ist. Außerdem können Zu-und Ableitung des Mediums von derselben Seite her erfolgen.With this arrangement one achieves that at the end of one hole the Medium is diverted into the other hole and the heating takes twice as long is exposed. In addition, the medium can be supplied and discharged from the same side be done here.

Wie die Figuren 5 und 6 zeigen, kann der Durchlauferhitzer auch nur mit einem Rohrheizkörper ausgerüstet werden0 Dieser liegt in einer einseitig zur Durchflußbohrung 2 angeordneten Nut 5 des Straußteils 11 und ist mit diesem wiederum verpresst. Für die Zu-und Ableitung des zu beheizenden Mediums ist an beiden Enden des Stranggußteils 11 je ein Stutzen 12 angedreht, auf den ein Schlauch 13 aufgeschoben werden kann.As FIGS. 5 and 6 show, the water heater can also only be equipped with a tubular heating element 0 This is on one side to the Flow hole 2 arranged groove 5 of the bouquet part 11 and is in turn with this pressed. For the supply and discharge of the medium to be heated is at both ends of the continuously cast part 11 each screwed on a nozzle 12 onto which a hose 13 is pushed can be.

Mit diesem beschriebenen Aufbau in den verschiedenen Varianten lassen sich Durchlauferhitzer jeder beliebigen Länge herstellen, doh auch sehr lange Erhitzer mit 0o5 m und mehr, beispielsweise zur Erwärmung von Ölen, ohne daß dazu aufwendige Löt,-oder Schweißarbeitsgänge erforderlich sind. Die Verwendung von Rohrheizkörpern der beschriebenen Art hat außerdem noch den Vorteil, daß die Durchlauferhitzer weitgehend feuchtigkeitsdicht ausgeführt werden können,Leave with this described structure in the different variants Instantaneous water heaters of any length can be produced, including very long heaters with 0o5 m and more, for example for heating oils, without the need for expensive Soldering or welding operations are required. The use of tubular heaters the type described also has the advantage that the water heater largely can be made moisture-proof,
