Abstract
Description
Die Erfindung betrifft einen "Kompaktdurchlauferhitzer".The invention relates to a "compact instantaneous water heater".
Aus dem Stand der Technik sind unterschiedliche Bauformen von Durchlauferhitzern bekannt.Different types of water heaters are known from the prior art.
Durchlauferhitzer dienen dem Erwärmen von Flüssigkeiten. Sie funktionieren auf verschiedene Arten. Grundsätzlich unterscheidet man Umströmung und Durchströmung von Heizungen. Beim Umströmungsprinzip wird eine Wärmequelle von einer Flüssigkeit umströmt. Beim Durchströmungsprinzip wird eine Wärmequelle von einer Flüssigkeit durchströmt. Bei Wärmequellen, die Ihrerseits erwärmte Fluide sind, werden die Bauformen Gegenstrom und Gleichstrom unterschieden. Beim Gegenstromprinzip strömen warmes Fluid und zu erwärmendes Fluid entgegengesetzt. Im Gleichstromprinzip strömen beide Fluide in gleicher Richtung.Instantaneous water heaters are used to heat liquids. They work in different ways. Basically, a distinction between around flow and flow through heaters. When Umströmungsprinzip a heat source is flowed around by a liquid. In the flow principle, a heat source is flowed through by a liquid. For heat sources, which in turn are heated fluids, the types of countercurrent and direct current are differentiated. In the counterflow principle, warm fluid and fluid to be heated flow in opposite directions. In the DC principle, both fluids flow in the same direction.
Aus diesen Bauformen lassen sich verschiedene Kombinationen aufbauen.From these designs, various combinations can be built.
Der Nachteil dieser verschiedenen Kombinationen ist zum einen die Baugröße der Geräte, zum anderen die Komplexität und dadurch bedingt die Kosten für die Herstellung und den Betrieb.The disadvantage of these different combinations is on the one hand the size of the devices, on the other hand the complexity and thereby the costs for the production and the operation.
Ausgehend von diesem Stand der Technik liegt der Erfindung insoweit die Aufgabe zugrunde, einen Durchlauferhitzer anzugeben, der eine möglichst geringe Baugröße hat, dadurch eine möglichst kleine Außenfläche und eine möglichst große Heizfläche aufweist und flexibel und mobil durch unterschiedliche Stromquellen versorgt werden kann, um somit den Kundennutzen entscheidend zu verbessern und Umweltbelastungen zu reduzieren.Based on this prior art, the invention is so far the object of specifying a water heater, which has the smallest possible size, thereby having the smallest possible outer surface and the largest possible heating surface and can be supplied flexibly and mobile by different power sources, thus the To significantly improve customer benefits and reduce environmental impact.
Diese Aufgabe wird dadurch gelöst, dass in einen möglichst flachen, plattenartigen, metallischen Körper eine Bahn idealer Weise als archimedische Spirale zur Durchleitung des Fluids eingebracht wird. Es lässt sich durch diese Gestaltung der Durchströmung der Heizung nicht nur die Baugröße reduzieren sondern dadurch auch die Wärmeverluste durch eine reduzierte Außenoberfläche. Ein weiterer Vorteil der spiralartigen Ausführung der Leitung ist eine Verlängerung der Durchströmungsdauer der Heizung bei reduzierter Baugröße. Es ist daher möglich, im Vergleich zum Stand der Technik, bei reduzierter Baugröße die Durchströmzeit des Fluids durch das Gerät zu verlängern und somit bei gleicher Temperaturerhöhung und gleichem Volumenstrom weniger elektrische Leistung aufzuwenden. Dies macht es wiederum möglich, weniger leistungsstarke Stromquellen einzusetzen. Speziell bei mobilen Anwendungen ist es dadurch möglich, die Stromversorgung zum Beispiel durch Batterien oder Solarzellen zu ermöglichen. Die in einer besonderen Bauform verwendeten Dickschicht-Heizelemente ermöglichen zudem den Betrieb an Wechsel- und Gleichspannung und einen Spannungsbereich von 0V - 400V. Daher können diese Geräte ohne aufwendige elektrische Schaltungen variabel durch verschieden Stromquellen versorgt werden. Bei Dickschicht-Heizelementen wird eine Dickschichtpaste mit einem hohen ohmschen Widerstand auf eine Trägerplatte aufgebracht. An diese Paste wird die genannte Versorgungsspannung angelegt.This object is achieved in that in a flat, plate-like, metallic body, a web is ideally introduced as an Archimedean spiral for the passage of the fluid. This configuration of the flow through the heater not only reduces the overall size but also reduces the heat losses due to a reduced external surface. Another advantage of the spiral-like design of the line is an extension of the flow duration of the heater with a reduced size. It is therefore possible, compared to the prior art, with reduced size to extend the flow time of the fluid through the device and thus spend less electrical power at the same temperature increase and the same volume flow. This in turn makes it possible to use less powerful power sources. Especially in mobile applications, this makes it possible to provide the power supply, for example, by batteries or solar cells. The thick-film heating elements used in a special design also allow operation on AC and DC voltage and a voltage range of 0V - 400V. Therefore, these devices can be supplied without complex electrical circuits variably by different power sources. For thick-film heating elements, a thick-film paste with a high ohmic resistance is applied to a carrier plate. The said supply voltage is applied to this paste.
