Aufgabe der Erfindung ist es, bei einem Flüssigkeitserhitzer, mit dem die Flüssigkeit, insbesondere Wasser, nicht verdampft werden soll, eine gute Wärmeübertragung der Heizleistung auf die Flüssigkeit durch in Strömungsrichtung örtliche Anpassung der Strömungsgeschwindigkeit und/oder der Heizleistung zu erreichen.task the invention is in a liquid heater with the the liquid, especially water, should not be evaporated, good heat transfer the heating power on the liquid by local in the direction of flow Adjustment of the flow rate and / or to achieve the heating output.
Erfindungsgemäß ist obige Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention is the above Object achieved by the features of claim 1.
Dadurch, dass der Strömungsraum zwischen dem Außenmantelteil und dem Innenrohr besteht, lässt sich der Strömungsquerschnitt in Strömungsrichtung auf baulich einfache Weise verkleinern. Dies kann dadurch erfolgen, dass der Strömungsraum sich in Strömungsrichtung konisch verjüngend gestaltet ist und/oder in dem Strömungsraum ein wendelförmiger Strömungsleitkörper angeordnet ist, dessen Steigung sich in Strömungsrichtung entsprechend ändert. Durch die Verkleinerung des Strömungsquerschnitts in Strömungsrichtung erhöht sich die Strömungsgeschwindigkeit in Strömungsrichtung, wodurch der Flächenheizkörper weniger Wärme aufnehmen kann.Thereby, that the flow space between the outer jacket part and the inner tube the flow cross-section in the direction of flow downsize in a structurally simple manner. This can be done that the flow space itself in the direction of flow tapered is designed and / or a helical flow guide body is arranged in the flow space is, the slope of which is in the direction of flow changes accordingly. By reducing the flow cross-section in the direction of flow elevated the flow rate in the direction of flow, making the panel radiator less Absorb heat can.
Durch das Aufbringen wenigstens eines Flächenheizkörpers, insbesondere Dickschicht-Heizkörpers, auf das Außenmantelteil oder an das Innenrohr, lässt sich in einfacher Weise die Heizleistung in Strömungsrichtung dadurch abnehmend gestalten, dass der Flächenheizkörper einen mehr oder weniger großen Bereich des Umfangs des Außenmantelteils oder des Innenrohrs einnimmt.By the application of at least one surface heating element, in particular a thick-film heating element the outer jacket part or on the inner tube the heating power decreases in the flow direction in a simple manner design that the panel radiator one more or less large Area of the circumference of the outer jacket part or of the inner tube.
Es ist also möglich, auf verschiedene Weise eine in Strömungsrichtung örtliche Anpassung der Heizleistung an die Flüssigkeitsströmung zu gestalten. Diese Möglichkeiten können kombiniert zum Einsatz kommen.It is possible local in the flow direction in different ways Adaptation of the heating output to the liquid flow shape. These opportunities can can be used in combination.
Der Flächenheizkörper ist bevorzugt dort angeordnet, wo er mit der Flüssigkeit nicht in Kontakt kommt, also an der Außenseite des Außenmantelteils oder an der Innenseite des Innenrohrs – wenn dieses nicht als Strömungsraum für die Flüssigkeit genutzt wird –.The Panel radiator is preferably arranged where it does not come into contact with the liquid, so on the outside of the outer jacket part or on the inside of the inner tube - if this is not a flow space for the Liquid used becomes -.
Der/die Flächenheizkörper können am Außenmantelteil oder am Innenrohr achsparallel verlaufen oder wie der Strömungsleitkörper gewendelt verlaufen.Of / Panel radiators can on Outer-shell part or run parallel to the axis of the inner tube or coiled like the flow guide run.
Vorzugsweise bildet das Innenrohr einen weiteren Strömungsraum für die Flüssigkeit. Dieser weitere Strömungsraum kann in Strömungsrichtung dem zwischen dem Außenmantelteil und dem Innenrohr bestehenden ersten Strömungsraum folgen oder diesem vorangehen. Der weitere Strömungsraum kann der Strömungsberuhigung und/oder dem Temperaturausgleich in der Strömung dienen. Baulich ermöglicht der weitere Strömungsraum den Flüssigkeitszulauf und den Flüssigkeitsauslauf an der gleichen Seite des Flüssigkeiterhitzers bzw. des Außenmantelteils vorzusehen.The inner tube preferably forms a further flow space for the liquid. This further flow space can follow in the flow direction or between the first flow space existing between the outer jacket part and the inner tube precede this. The further flow space can serve to calm the flow and / or to equalize the temperature in the flow. Structurally, the further flow space enables the liquid inlet and the liquid outlet to be provided on the same side of the liquid heater or of the outer jacket part.
