Description

Die Erfindung bezieht sich auf einen Durchlauferhitzer nach dem Oberbegriff des Anspruches 1.The invention relates to a water heater according to the preamble of claim 1.

Es ist bereits ein Durchlauferhitzer der im Oberbegriff des Anspruches 1 genannten Art vorgeschlagen worden. Die Kanalbahnen sind hier die Schenkel eines U- förmig verlaufenden Kanals. Diese Ausbildung ist besonders für Durchlauferhitzer von Kaffeemaschinen geeignet, bei denen es je nach Konstruktion als vorteilhaft angesehen wird, die Enden des Kanals auf der gleichen Seite zu haben. Als Vorwärmer von Heizöl wäre der bekannte Durchlauferhitzer weniger geeignet. Bei Durchlauferhitzern für die Vorwärmung von Heizöl ist es oft wünschenswert, die Strömung des Heizöls möglichst ohne Richtungsänderung verlaufen zu lassen. Ferner besteht insbesondere die Forderung, das Heizöl innerhalb der Lüftervorlaufzeit eines Ölbrenners von der unbeeinflußten Vorlauftemperatur auf etwa 60° C im Düsenbereich des Brenners anzuwärmen. Die Vorlaufzeit des Lüfters beträgt etwa 15 Sekunden. Mit dem Durchlauferhitzer nach dem Oberbegriff des Anspruches 1 sind diese Forderungen nicht erfüllbar.A instantaneous water heater of the type mentioned in the preamble of claim 1 has already been proposed. The channel tracks here are the legs of a U-shaped channel. This design is particularly suitable for instantaneous water heaters of coffee machines, where, depending on the construction, it is considered advantageous to have the ends of the channel on the same side. The known instantaneous water heater would be less suitable as a preheater for heating oil. In the case of instantaneous heaters for preheating heating oil, it is often desirable to allow the flow of the heating oil to run as far as possible without changing its direction. There is also a particular requirement that the heating oil within the fan lead time of an oil burner from the unaffected flow temperature to about 6 0 ° C in the nozzle area of the Warm up the burner. The fan lead time is approximately 15 seconds. With the instantaneous water heater according to the preamble of claim 1, these requirements cannot be met.

Der Erfindung liegt die Aufgabe zu Grunde, den Durchlauferhitzer der im Oberbegriff des Anspruches 1 genannten Gattung so auszubilden, daß er zum Aufheizen von Heizöl geeignet ist. Insbesondere soll mit dem zu schaffenden Durchlauferhitzer Heizöl innerhalb der Vorlaufzeit eines Lüfters, also etwa innerhalb von etwa 15 Sekunden, auf eine Temperatur von ungefähr 60° C aufheizbar sein.The invention is based on the object, the water heater of the type mentioned in the preamble of claim 1 so that it is suitable for heating heating oil. In particular to the fuel oil to be created within the water heater lead time of a fan, so as within about 15 seconds to be heated up to a temperature of approximately 6 0 ° C.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 angegebene Ausbildung gelöst.The object is achieved by the training specified in the characterizing part of claim 1.

Zweckmäßige Aus- und Weiterbildungen des Erfindungsgegenstandes sind in den Ansprüchen 2 bis 6 angegeben.Appropriate training and further developments of the subject matter of the invention are specified in claims 2 to 6.

Die erfindungsgemäße Ausbildung hat den Vorteil, daß das Heizöl unmittelbar das die Heizelemente und deren Beilagen umgebende Hüllrohr benetzt, so daß dem Wärmefluß von den Heizelementen zum Heizöl nur wenig Widerstand entgegengesetzt wird, da die Masse der dazwischen liegenden Bauteile sehr gering ist. Ein weiterer Vorteil besteht darin, daß im Betrieb des Durchlauferhitzers der Momentanwert des Volumens der in jeder Kanalbahn befindlichen Ölsäule sehr gering ist. Die jeweils in den Kanalbahnen befindlichen Ölsäulen ..sind daher massearm, was die Aufheizzeit günstig beeinflußt. Auch die übrige Ausgestaltung ist infolge der Ausbildung des Kerns sehr massearm, was kurze Aufheizzeiten begünstigt.The design according to the invention has the advantage that the heating oil directly wets the cladding tube surrounding the heating elements and their inserts, so that there is little resistance to the heat flow from the heating elements to the heating oil, since the mass of the components in between is very small. Another advantage is that the instantaneous value of the volume of the oil column located in each channel path is very low during operation of the instantaneous water heater. The oil columns in each of the channel tracks are therefore low in mass, which has a favorable effect on the heating-up time. The rest of the design is very much due to the formation of the core Low mass, which favors short heating times.

  • Fig. 1 einen Querschnitt eines Durchlauferhitzers, mit einem flachgedrückten Hüllrohr,
  • Fig. 2 einen Querschnitt eines Durchlauferhitzers, mit einem runden Hüllrohr,
  • Fig. 3 einen Ausschnitt aus Fig. 1,
  • Fig. 4 einen Ausschnitt aus Fig. 2.
The object of the invention is shown in the drawing, for example, and purely schematically. Show it:
  • 1 shows a cross section of a continuous-flow heater with a flattened cladding tube,
  • 2 shows a cross section of a continuous-flow heater, with a round cladding tube,
  • 3 shows a detail from FIG. 1,
  • 4 shows a detail from FIG. 2.

In der Darstellung ist jeweils mit 1 ein Heizelement aus kaltleitendem Material bezeichnet. In nicht dargestellter Weise liegen mehrere Heizelemente 1 hintereinander.In the illustration, 1 denotes a heating element made of cold-conducting material. In a manner not shown, several heating elements 1 are located one behind the other.

Die Heizelemente 1 sind samt sie beidseits bedeckenden Stromzuführungselektroden 2 und einer die Zuführungselektroden 2 bedeckenden elektrischen Isolation 3 in einem dünnwandigen Hüllrohr eingepackt.The heating elements 1 together with the power supply electrodes 2 covering them on both sides and an electrical insulation 3 covering the supply electrodes 2 are packed in a thin-walled cladding tube.

In den Fig. 1 und 3 ist das Hüllrohr mit 4 bezeichnet und flach an die elektrische Isolation 3 angedrückt.1 and 3, the cladding tube is designated 4 and pressed flat against the electrical insulation 3.

Das Hüllrohr 4 liegt zwischen zwei Trägerteilen 7a, 7b. Jedes der Trägerteile 7a, 7b besitzt drei Kanalbahnen 8, die parallel zum Hüllrohr 4 verlaufen. Die schlecht wärmeleitenden Trägerteile 7a, 7b sind in einem sie in der Bestimmungslage haltenden Außenrohr 9 angeordnet.The cladding tube 4 lies between two carrier parts 7a, 7b. Each of the carrier parts 7a, 7b has three channel tracks 8 which run parallel to the cladding tube 4. The poorly heat-conducting carrier parts 7a, 7b are arranged in an outer tube 9 holding them in the determination position.

Abschnitte des Hüllrohres 4 bilden jeweils eine Wand der Kanalbahnen 8.Sections of the cladding tube 4 each form a wall of the channel tracks 8.

Die Kanalbahnen 8 gehen in nicht gezeigter Weise vor und hinter dem Hüllrohr 4 in einen einzigen Durchflußquerschnitt über. Beispielsweise kann vor und hinter dem Hüllrohr 4 jeweils ein vom Außenrohr 9 begrenzter Sammelraum angeordnet sein, in den zentrisch ein Zu - bzw. Abflußkanal mündet.The channel tracks 8 go in a manner not shown in front of and behind the cladding tube 4 into a single flow cross section. For example, a collecting space delimited by the outer tube 9 can be arranged in front of and behind the cladding tube 4, into which an inflow or outflow channel opens centrally.

Die Kanalbahnen 8 besitzen einen Querschnitt für einen dünnen, massearmen Heizölstrom, das heißt sie sind sehr flach und klein im Querschnitt, so daß das sie durchströmende Heizöl schnell aufheizbar ist. Die schnelle Aufheizung wird dadurch begünstigt, daß das Heizöl das Hüllrohr 4 benetzt.The channel tracks 8 have a cross section for a thin, low-mass heating oil flow, that is, they are very flat and small in cross section, so that the heating oil flowing through them can be heated quickly. The rapid heating is favored in that the heating oil wets the cladding tube 4.

Die.Kanalbahnen 8 nach Fig. 1 sind im Querschnitt kreisbogenförmig,Die.Kanalbahnen 8 of Fig. 1 are arcuate in cross section,

Anstelle der drei Kanalbahnen 8 kann auch eine einzige, im Querschnitt etwa rechteckige" Kanalbahn 8a vorgesehen werden, wie in Fig. 3 gezeigt.Instead of the three channel tracks 8, a single "channel track 8a, which is approximately rectangular in cross section, can also be provided, as shown in FIG. 3.

Bei dem Ausführungsbeispiel nach den Fig. 2 und 4 ist das Hüllrohr rund und mit 12 bezeichnet. Zwischen der elektrischen Isolation 3 und dem Hüllrohr 12 ist jeweils zum Auffüllen des Zwischenraumes ein kreisabschnittförmiges, gut wärmeleitendes Zwischenstück 13 angeordnet.In the embodiment according to FIGS. 2 and 4, the cladding tube is round and designated by 12. Between the electrical insulation 3 and the cladding tube 12, a circular section-shaped, good heat-conducting intermediate piece 13 is arranged in each case to fill up the intermediate space.

Entsprechend dem Hüllrohr 12 ist ein runder Träger 14 vorgesehen, der von einem mit 15 bezeichneten Außenrohr umgeben ist und den Zwischenraum zwischen dem Außenrohr 15 und dem Hüllrohr 12 ausfüllt. Das Außenrohr 15 kann aus wärmeisolierendem Material bestehen. Falls eine Wärmeisolation nicht erwünscht ist, kann das Außenrohr 15 entfallen.Corresponding to the cladding tube 12, a round support 14 is provided, which is surrounded by an outer tube denoted by 15 and fills the space between the outer tube 15 and the cladding tube 12. The Outer tube 15 can consist of heat-insulating material. If thermal insulation is not desired, the outer tube 15 can be omitted.

Auch bei dem Ausführungsbeispiel nach den Fig. 2 und 4 bilden Abschnitte des Hüllrohres 12 jeweils eine Wand der hier mit 16 bezeichneten Kanalbahnen. Diese Kanalbahnen 16 sind am Umfang des Hüllrohres 12 gleichmäßig verteilt angeordnet und gehen, wie beim Ausführungsbeispiel nach den Fig. 1 und 3 beschrieben, in nicht dargestellter Weise vor und hinter dem Hüllrohr 12 in einen einzigen Durchflußquerschnitt über. Sie besitzen auch einen Querschnitt für einen dünnen massearmen Heizölstrom, das heißt, sie sind ebenfalls sehr flach und klein im Querschnitt.In the exemplary embodiment according to FIGS. 2 and 4, sections of the cladding tube 12 each form a wall of the channel tracks designated 16 here. These channel tracks 16 are arranged distributed uniformly on the circumference of the cladding tube 12 and, as described in the exemplary embodiment according to FIGS. 1 and 3, merge in a manner not shown in front of and behind the cladding tube 12 into a single flow cross section. They also have a cross-section for a thin, low-mass fuel oil flow, which means that they are also very flat and small in cross-section.

Der Querschnitt der Kanalbahnen 16 ist nach Fig. 2 etwa kreisbogenförmig. Er kann aber auch nach Fig. 4 etwa rechteckig sein. Die Kanalbahnen sind dort mit 16a bezeichnet.The cross section of the channel tracks 16 is approximately circular arc shaped according to FIG. 2. However, it can also be approximately rectangular according to FIG. 4. The channel tracks are designated 16a there.
