Abstract
Description
Die Erfindung betrifft eine Heizgerät insbesondere gemäß Oberbegriff des Patentanspruches 1.The Invention relates to a heater in particular according to the preamble of claim 1.
Heizgeräte der eingangs
genannten Art sind bspw. nach der
Diese relativ aufwendige Konstruktion zu vereinfachen, insbesondere sich über den gesamten Heizgerätequerschnitt abdeckende Hohlplatinen zu vermeiden und für eine möglichst gleichmäßige Beaufschlagung der parallel geführten Wärmetauscher bzw. Flachrohre zu sorgen, liegt der Erfindung als Aufgabe zugrunde, und zwar verbunden mit der Maßgabe, dabei insgesamt günstigere Fertigungsvoraussetzungen zu schaffen.These to simplify relatively complex construction, in particular over the entire heater cross section To avoid covering hollow boards and for a uniform as possible loading the parallel run Heat exchanger or To provide flat tubes, the invention has for its object, and connected with the proviso, overall cheaper Create manufacturing prerequisites.
Diese Aufgabe ist mit einem Heizgerät der eingangs genannten Art durch die im Kennzeichen des Patentanspruches 1 angeführten Merkmale gelöst.These Task is with a heater of the type mentioned by the in the characterizing part of claim 1 quoted Characteristics solved.
Diese erfindungsgemäße Ausbildung ist zwar insbesondere für Heizgeräte bestimmt, deren Wärmetauscher aus mindestens zwei Rohrwendeln bestehen, bei denen es also gilt, die beteiligten Flachrohrwendeln miteinander hydraulisch zu verbinden, an ihren Enden zu verschließen und für gemeinsame Heizmediumsanschlüsse zu sorgen. Es hat sich aber gezeigt, daß die erfindungsgemäße Lösung vorteilhaft auch für Heizgeräte geeignet ist, die bspw. aufgrund geringerer Leistungsanforderung mit nur einem gewendelten Flachrohr auskommen. Diesbezüglich wird auf den unabhängigen Patentanspruch 11 verwiesen, dessen Ausführungsform sonst unmittelbar an den Wendelenden selbst vorzunehmende Abschluß- und Anschlußmaßnahmen für die Heizmediumsanschlüsse vorteilhaft entbehrlich macht.These inventive training is especially for heaters determines their heat exchanger consist of at least two coiled tubing, which therefore hydraulically connect the flat tube coils involved to close at their ends and for common heating medium connections to care. However, it has been found that the solution according to the invention is advantageous also for heaters is suitable, for example, due to lower power requirement get along with only one coiled flat tube. This will be on the independent Patent claim 11, whose embodiment otherwise directly at the helix ends themselves to be made final and follow-up measures for the heating medium connections advantageous dispensable.
Vorteilhafte Weiterbildungen zu den unabhängigen Patentansprüchen 1. und 11. ergeben sich nach den Unteransprüchen.advantageous Further education to the independent ones claims 1st and 11th arise according to the subclaims.
Mit die erfindungsgemäßen Lösung gemäß Patentanspruch 1, für die nachfolgend auf zwei Wärmetauscher bzw. Wendeln Bezug genommen wird, sind die gestellten Forderungen erfüllt. Abgesehen davon, daß die kappenartigen Verteilergehäuse mit ihren Heizmediumsanschlüssen zunächst unabhängig von den Wärmetauscherwendeln hergestellt werden können und an den Wendeln selbst, abgesehen von der flüssigkeitsdichten Verbindung ihrer benachbart verlaufenden Wände, weder Überströmöffnungen noch sonstige besondere Fertigungseingriffe vorzunehmen sind, erfüllt die erfindungsgemäße Ausbildung der beiden Wärmetauscherwendeln als wesentliches Element des Heizgerätes eine Doppelfunktion, nämlich zum Einen wird die hydraulische Verbindung der beiden Wendeln durch die Verteilergehäuse hergestellt, die gleichzeitig eine bequemen Ansatz für die Vor- und Rücklaufanschlüsse darstellen, und zum Anderen wird der Heizmediumsrücklauf unmittelbar und konzentriert den beiden Wendelenden zugeführt bzw. vorlaufseitig der Heizmediumsvorlauf entsprechend konzentriert abgeführt. Außerdem sind, da die bisherigen Hohlplatinen wegfallen, an den Abschlußwänden für die Brennkammer keine steigungsangepaßten Anschlußverformungen für die schräg zulaufenden Wendelenden zu berücksichtigen, sondern lediglich einfache Durchgriffsöffnungen für die Heimediumsanschlüsse, die parallel zur Achse der Brennkammer am Heizgerät abgehen.With the solution according to the invention according to claim 1, for following on two heat exchangers or spirals is made, are the demands made Fulfills. Apart from the fact that the cap-like distributor housing with their heating medium connections first independently from the heat exchanger coils can be produced and on the coils themselves, except for the fluid tight connection their adjacent walls, neither overflow openings still other special manufacturing interventions are to be made, meets the inventive training the two heat exchanger coils as an essential element of the heater a double function, namely for One is the hydraulic connection of the two coils through the distributor housing which at the same time provide a convenient approach to the supply and return connections, and second, the heating medium return is immediately and concentrated supplied to the two coil ends or on the supply side of the heating medium flow accordingly concentrated dissipated. Furthermore are, since the previous hollow boards omitted, on the end walls for the combustion chamber no gradient-adjusted connection deformations for the sloping Wendelenden to consider but only simple access openings for the home telephone connections, the Go off parallel to the axis of the combustion chamber on the heater.
Vorteilhaften
Weiterbildungen gemäß der abhängigen Ansprüche zum
Patentanspruch 1 bestehen in Folgendem:
Die kappenartigen Verteilergehäuse sind
im quer zur Strömungsrichtung
des Heizmediums gesehenen Schnitt im Wesentlichen dem Öffnungsquerschnitt beider
Wendelenden entsprechend ausgebildet, d.h., die beiden kappenartigen
Verteilergehäuse
beanspruchen praktisch keinen zusätzlich Raum und stellen insoweit
nur eine außenkonturseitige
Fortsetzung der Wendelenden dar.Advantageous developments according to the dependent claims for claim 1 consist in the following:
The cap-like distributor housing are formed in cross-section to the flow direction of the heating medium substantially corresponding to the opening cross-section of both spiral ends, ie, the two cap-like distributor housing occupy practically no additional space and represent insofar only a Außenkonturseitige continuation of the coil ends.
Die Zu- und Abströmöffnungen an den Wendelenden sind in einer in Bezug auf die Strömungsrichtung schräg orientierten Ebene angeordnet, an die die entsprechend aber entgegengesetzt geschnittenen Verteilergehäuse angesetzt sind. Dies führt, was noch näher zu erläutern sein wird, zu einer weiter verbesserten gleichmäßigen Verteilung des Heizmediums auf die beiden Wendeln. Davon ausgehend, sind die Verteilergehäuse in Seitenansicht im Wesentlichen als rechtwinklige Dreiecke ausgebildet, deren Hypothenuse die Anschlußseite für die Wendelenden bildet und an deren größerer Kathede der Heizmediumsanschluß angeordnet ist.The Inlet and outlet openings At the helical ends are in one with respect to the flow direction aslant oriented level, to which the corresponding but opposite cut distributor housing are attached. This leads, what even closer to explain will be, to a further improved uniform distribution of the heating medium on the two coils. Based on this, the distributor housings are in side view formed essentially as right-angled triangles whose hypotenuse the connection side for the Spiral ends forms and arranged at the larger Kathede the heating medium connection is.
Ferner sind die Verteilergehäuse in Bezug auf die Rücklaufzuführung und auch den abströmenden Vorlauf vom unteren Flachrohr bzw. der unteren Flachrohrwendel ausgehend mit ansteigender Hypothenuse angeordnet.Furthermore, the distributor housings are in relation to the return supply and also the outflow arranged the flow from the lower flat tube or the lower flat tube spiral starting with rising hypotenuse.
Um auch im Inneren der Verteilergehäuse die Strömungsverteilung in Bezug auf die beiden Wendeln zu optimieren, können die den angesetzten Wendelenden gegenüberstenden Abschlußwände der Verteilergehäuse vorteilhaft konkav gewölbt oder innenseitig konkav profiliert ausgebildet sein.Around also inside the distributor housing the flow distribution In terms of the two coils to optimize, which can be applied coil ends against Tenden End walls of the distributor housing advantageous concave arched or be concave profiled on the inside.
Die Verteilergehäuse können dabei in Form von Tiefziehteilen ausgebildet werden oder auch in der Weise, daß die Verteilergehäuse jeweils aus einem ihrer Endform entsprechendem und aufzufaltendem Blechzuschnitt gebildet sind. Möglich ist aber auch, die Verteilergeäuse bspw. aus Feinguß herzustellen, was den Vorteilhat, daß dabei die Heizmediumsanschlüsse direkt mit ausgeformt bzw. gegossen werden können.The distributor housing can be formed in the form of deep-drawn parts or in the Way, that the distributor housing each from one of their final form corresponding and aufzufaltendem Sheet metal blank are formed. Possible but it is also the distributor housing for example, from investment casting, which has the advantage of being there the heating medium connections can be molded directly with or poured.
Das erfindungsgemäße Heizgerät und vorteilhafte Weiterbildungen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The Heating device according to the invention and advantageous Further developments are described below with reference to the drawings of exemplary embodiments explained in more detail.
