Abstract
Description
Die Erfindung betrifft einen Wärmetauscher gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a heat exchanger according to the Preamble of claim 1.
Ein
Wärmetauscher der eingangs genannten Art ist nach der
Der Erfindung liegt die Aufgabe zugrunde, bei einem rohrwendelförmigen Wärmetauscher mit horizontaler Wendelachse für eine möglichst gute Entlüftbarkeit zu sorgen, und zwar unabhängig davon, ob dieser Wärmetauscher die oben beschriebenen Vor- und Rücklaufanschlüsse aufweist oder nicht.Of the Invention is based on the object, in a pipe-helical Heat exchanger with horizontal helical axis for to ensure the best possible ventibility, regardless of whether this heat exchanger the flow and return connections described above or not.
Diese Aufgabe ist mit einem Wärmetauscher der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst. Dabei ist festzuhalten, dass der erfindungsgemäße Wärmetauscher nicht auf die Anwendung in einem Heizkessel beschränkt ist, sondern vielmehr zum Beispiel auch bei Warmwasserspeichern eingesetzt werden kann (in diesem Fall wird der Wärmetauscher nicht von einem Abgas eines Brenners, sondern von aufzuwärmenden Wasser umströmt), bei denen ebenfalls das Problem der verschlechterten Wärmeübertragung durch Gaseintrag auftreten kann.These Task is with a heat exchanger of the aforementioned Type by the listed in the characterizing part of claim 1 Characteristics solved. It should be noted that the inventive Heat exchanger does not apply to a boiler is limited, but rather, for example, at Hot water storage can be used (in this case the heat exchanger is not from an exhaust gas of a burner, but flows around to be heated water), in which also the problem of deteriorated heat transfer can occur due to gas entry.
Nach der Erfindung ist also vorgesehen, dass die Rohrwendel einen zweiteiligen Durchströmquerschnitt aufweist, wobei der erste, größere Durchströmquerschnitt für das Wärmeträgermedium vorgesehen und der zweite, kleinere Durchströmquerschnitt als Entlüftungswendel ausgebildet ist, wobei diese pro Wendelgang im Bereich des oberhalb der Wendelachse befindlichen Rohrwendelteils mindestens eine den ersten mit dem zweiten Durchströmquerschnitt verbindende Entlüftungsöffnung aufweist.To The invention is therefore intended that the coiled tubing is a two-part Having flow cross-section, wherein the first, larger Flow cross section for the heat transfer medium provided and the second, smaller flow area is designed as vent helix, this pro Spiral passage in the area of above the helix axis located Pipe helix part at least one of the first with the second flow cross-section having connecting vent.
Die Maßgabe eines "zweiteiligen Durchströmquerschnittes" beinhaltet dabei sowohl die Möglichkeit einer im Prinzip einstückigen Rohrwendel mit zwei Strömungsräumen als auch die Möglichkeit, dass in die Rohrwendel ein weiteres Bauteil eingebracht ist. Mit anderen Worten ausgedrückt, wird bei dieser Variante eine zusätzliche Rohrwendel (Entlüftungswendel) in der Rohrwendel angeordnet, wobei die pro Wendel vorzugsweise im obersten Bereich vorgesehene Entlüftungsöffnung ein Entweichen von sich möglicherweise angesammelter Luft bzw. Gas ermöglicht.The Specification of a "two-part flow cross-section" includes both the possibility of a in principle one-piece coiled tubing with two flow spaces as well as the possibility that in the coiled tub another Component is introduced. In other words, In this variant, an additional coiled tubing (venting helix) arranged in the coiled tubing, wherein the per coil preferably provided in the top area vent an escape of possibly accumulated air or Gas allows.
Zum
besseren Verständnis der Erfindung ist Folgendes zu beachten:
Bei rohrwendelförmigen Wärmetauschern mit horizontaler
Wendelachse besteht das prinzipielle Problem, dass sich mit dem Wärmeträgermedium
in den Wärmetauscher eintretendes Gas schwerkraftbedingt
im oberen Bereich der Rohrwendeln sammelt. Dies ist unerwünscht,
da dadurch die Wärmeübertragung verschlechtert
wird. Beim Ausführungsbeispiel gemäß der
Gemäß der Erfindung wird diesem Problem nun damit begegnet, dass genau an der Stelle, wo sich das Gas sammelt, für eine entsprechende Abführmöglichkeit gesorgt ist, nämlich dadurch, dass dort in der Entlüftungswendel mindestes eine Entlüftungsöffnung vorgesehen ist, über die das Gas abströmen kann.According to the Invention now addresses this problem so that exactly the place where the gas gathers, for a corresponding one Abführmöglichkeit is ensured, namely in that there in the venting helix at least one Vent is provided over which can drain the gas.
Die Maßgabe, dass die Entlüftungswendel querschnittskleiner als die Rohrwendel sein soll, ist dabei einerseits zwingend, da sie sonst gar nicht in der Rohrwendel angeordnet sind könnte, andererseits hat diese Maßgabe aber auch zur Folge, dass vorallem das Gas und nur zu sehr kleinen Teilen das Wärmeträgermedium über die Entlüftungswendel abströmen kann. Hierauf wird weiter unten noch genauer eingegangen.The Assuming that the vent coil cross-section smaller as the coiled tubing is to be, on the one hand mandatory because otherwise they could not be arranged in the coiled tubing, On the other hand, this requirement also has the consequence that, above all the gas and only very small parts of the heat transfer medium over the venting coil can flow out. hereupon will be discussed in more detail below.
Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Wärmetauschers ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the invention Heat exchanger resulting from the dependent Claims.
Der erfindungsgemäße Wärmetauscher einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung verschiedener Ausführungsbeispiele näher erläutert.Of the including heat exchangers according to the invention its advantageous developments according to the dependent claims will be described below the graphic representation of various embodiments explained in more detail.
