Description

Plattenradiator Plate radiator
Die Erfindung bezieht sich auf einen Plattenradiator mit fest eingebauter Ventil- und Anschlußgarnitur, welche mit einem an einer Seite des Plattenradiators oben angeordneten Regel¬ ventil versehen ist, welches am gleichfalls dort placierten, in einen oberen Radiatorplattensammel anal einmündenden Radiator¬ plattenzulaufanschluß angeordnet ist, und welche Verbindungs¬ rohre beinhaltet, die vom Regelventil und von einem in einen unteren Radiatorplattensammelkanal des Plattenradiators einmündenden Radiatorplattenrücklaufanschluß zu unten am Plattenradiator vorgesehenen radiatorseitigen lösbaren Anschlußverschraubungen führen.The invention relates to a plate radiator with a permanently installed valve and connection set, which is provided with a control valve arranged on one side of the plate radiator, which is arranged on the radiator plate inlet connection, which is also placed there and opens into an upper radiator plate collection, and which contains connecting pipes which lead from the control valve and from a radiator plate return connection opening into a lower radiator plate collecting duct of the plate radiator to the radiator-side detachable screw connections provided at the bottom of the plate radiator.
Es sind Plattenradiatoren vorgenannter Art bekannt, bei denen die fest eingebaute Ventil- und Anschlußgarnitur einem Seitenrand einer Radiatorplatte folgend angeordnet ist und sich sowohl der Radiatorplattenzulaufanschluß, an welchem das Regel¬ ventil angeordnet ist, als auch der Radiatorplattenrücklaufan- schluß an der gleichen Seite des Radiators befinden, und die Anschlußverschraubungen der Ventil- und Anschlußgarnitur, welche mit den zum Radiator führenden Zuleitungen zu verbinden sind, gleichfalls im Bereich jenes Randes, an dem sich das Regelventil und der Radiatorplattenrücklaufanschluß befinden, angeordnet sind. Eine solche Ausbildung eines Plattenradiators kann bei verschiedenen Anwendungsfällen zu Leistungsminderungen und zu Unbequemlichkeiten bzw. Erschwernissen bei der Montage solcher Radiatoren führen. So können sich bei größeren Baulängen von Plattenradiatoren in den vom Radiatorplattenzulaufanschluß und vom Radiatorplattenrücklaufanschluß fernen Bereichen des Radiators Zonen mit verminderter Wärmeabgabe bilden, weil die Zirkulation mit zunehmender Entfernung von den Radiatorplatten¬ anschlüssen schwächer wird, eine Erscheinung die gerade bei Plattenradiatoren zufolge des bei dieser Radiatorenart gegebenen höheren Durchflußwiderstandes vermehrt in Erscheinung treten kann und zu Minderungen der Wärmeabgabe führen kann. Die im Bereich eines Seitenrandes placierten Anschlußverschraubungen der Anschlußgarnituren verlangen eine exakte Placierung der Zuleitungsenden, welche auf die an den einzelnen Radiatorauf¬ stellungsplätzen einer Anlage vorgesehenen, in der Regel verschiedenen, Radiatorgrößen genau anzupassen ist, was erhöhte Sorgfalt bei der Leitungsverlegung erfordert. Falls sich die Notwendigkeit ergibt, einen anderen Radiator einzubauen, als bei der Planung und bei der Verlegung der Zuleitungen in Betracht gezogen war, kann daraus eine optisch ungünstige Placierung des betreffenden Radiators folgen oder sogar die Notwendigkeit resultieren, die Zuleitungen verändern zu müssen, um den Radiator überhaupt unterbringen zu können. Derartige Umstände können z.B. dann auftreten, wenn die Radiatoren, wie dies häufig der Fall ist, in Fensternischen montiert werden.Plate radiators of the aforementioned type are known, in which the permanently installed valve and connection set is arranged following a side edge of a radiator plate, and both the radiator plate inlet connection, on which the control valve is arranged, and the radiator plate return connection are located on the same side of the radiator are located, and the screw connections of the valve and connection set, which are to be connected to the leads leading to the radiator, are also arranged in the area of the edge on which the control valve and the radiator plate return connection are located. Such a design of a plate radiator can lead to reduced performance and to inconveniences or difficulties when installing such radiators in various applications. In the case of larger lengths of plate radiators, zones with reduced heat dissipation can form in the areas of the radiator remote from the radiator plate inlet connection and from the radiator plate return connection, because the circulation becomes weaker with increasing distance from the radiator plate connections, a phenomenon which is particularly the case with plate radiators due to this type of radiator given higher flow resistance can appear increasingly and lead to reductions in heat dissipation. The connection fittings of the connection fittings placed in the area of a side edge require an exact placement of the supply ends, which must be precisely adapted to the generally different radiator sizes provided at the individual radiator installation positions of a system, which increased Care must be taken when laying the cables. If there is a need to install a different radiator than was considered in the planning and laying of the supply lines, this may result in an optically unfavorable placement of the radiator in question or may even result in the need to change the supply lines in order to To be able to accommodate the radiator at all. Such circumstances can occur, for example, when the radiators, as is often the case, are installed in window recesses.
Es ist ein Ziel der vorliegenden Erfindung einen Radiator eingangs erwähnter Art zu schaffen, bei dem auch unter erschwerten Betriebsbedingungen eine gute und gleichmäßige Wärmeabgabe gegeben ist und der auch die hinsichtlich Leitungsverlegung und Montage erforderlichen Arbeiten sehr einfach und weitgehend standardisiert durchführen läßt.It is an object of the present invention to provide a radiator of the type mentioned at the beginning, in which good and uniform heat emission is given even under difficult operating conditions and which can also carry out the work required in terms of line laying and assembly in a very simple and largely standardized manner.
Der erfindungsgemäße Plattenradiator eingangs erwähnter Art ist dadurch gekennzeichnet, daß die lösbaren Anschlußverschrau¬ bungen in der Mitte der Unterseite des Radiators angeordnet sind und von diesen Anschlußverschraubungen ein im Radiator fest angeordnetes Verbindungsrohr zum Regelventil führt und ein weiteres im Radiator fest angeordnetes Verbindungsrohr zu einem in der dem Regelventil gegenüberliegenden Hälfte der Längser¬ streckung des Plattenradiators in den genannten unteren Radiatorplattensammelkanal einmündenden Radiatorplattenrücklauf- anschluß führt, und daß diese Verbindungsrohre vorzugsweise aus Stahl gebildet sind. Durch diese Ausbildung kann der vorstehend angeführten Zielsetzung gut entsprochen werden. Die mittige Anordnung der Anschlußverschraubungen der Ventil- und Anschlu߬ garnitur an-der Unterseite des Radiators ermöglicht es, die Zuleitungen bzw. deren zum Anschluß der Radiatoren vorgesehenen Enden in den zu beheizenden Räumen weitgehend standardisiert anzuordnen bzw. zu verlegen und z.B. jeweils mittig in Fenster¬ nischen ausmünden zu lassen und dabei weitgehend unabhängig von der Größe des am jeweiligen Anschlußort vorzusehenden Radiators eine ausgewogene Anbringung desselben zu erzielen, z.B. im Fall der Anbringung in einer Fensternische eine mittensymmetrische Anordung des Radiators, unabhängig von der jeweils erforder¬ lichen Größe desselben, was es auch ermöglicht, im Bedarfsfall eine andere Größe eines solchen Radiators einzusetzen, als in einem ursprünglichen Konzept vorgesehen war, ohne daß es dazu einer Veränderung der Lage der Ausmündungen der Zuleitungen be¬ darf und ohne daß bei einer solchen Veränderung der Radiator¬ größen eine deutlich merkbare Veränderung des Aussehens in Kauf genommen werden muß. Die zusammen mit der mittigen Anordnung der Anschlußverschraubungen in der Mitte der Unterseite des Radiators vorgesehene Verbindung dieser Anschlußverschraubungen mit einem seitlich oben am Radiator angeordneten Regelventil und mit einem in der diesem Regelventil gegenüberliegenden Hälfte der Längserstreckung des Plattenradiators in den unten ver¬ laufenden Radiatorplattensammelkanal einmündenden Radiator¬ plattenrücklaufanschluß, wobei das Heizmedium in einen beim Regelventil angeordneten Radiatorplattenzulaufanschluß in die betreffende Radiatorplatte eintritt, ergibt unabhängig von der Radiatorgröße eine weitgehend gleichmäßige Durchströmung der Radiatorplatten, so daß praktisch keine Minderungen der Wärme¬ abgabe, wie sie z.B. bei der oben erwähnten einseitigen Placierung von Vorlaufanschluß und Rücklaufanschluß vorliegen, auftreten. Es besteht auch jederzeit die Möglichkeit, bei Ver¬ änderung des Wärmebedarfs andere Radiatorgrößen als ursprünglich konzipiert einzusetzen, ohne die Zuleitungen ändern zu müssen. Diese Vorteile treten zu den günstigen Eigenschaften hinsicht¬ lich Bedienung und Regelung, welche sich aus der Anordnung des Radiatorregelventils seitlich oben am Radiator ergeben, hinzu. Es sind auch die Nachteile bisher bekannt gewordener Radiatoren mit mittig placierten Anschlußverschraubungenn, nämlich verminderte Wärmeabgabe und ungünstige Regelung und Bedienung der Ventile, vermieden.The plate radiator according to the invention of the type mentioned at the outset is characterized in that the detachable connecting screw connections are arranged in the center of the underside of the radiator and from these connecting screw connections a connecting pipe fixedly arranged in the radiator leads to the control valve and a further connecting pipe fixedly arranged in the radiator to one in the half of the longitudinal extension of the plate radiator opposite the control valve leads to the radiator plate return connection which opens into the lower radiator plate collecting duct and that these connecting tubes are preferably made of steel. With this training, the above-mentioned objective can be met well. The central arrangement of the screw connections of the valve and connection set on the underside of the radiator makes it possible to arrange or lay the supply lines or their ends intended for connecting the radiators in the rooms to be heated in a largely standardized manner and, for example, in the middle of windows ¬ niche to open and thereby achieve a balanced attachment of the radiator largely independent of the size of the radiator to be provided at the respective connection point, for example in the case of attachment in a window recess, a center-symmetrical arrangement of the radiator, regardless of the size required in each case, what it also makes it possible to use a different size of such a radiator than in an original concept was provided, without this requiring a change in the position of the outlets of the feed lines and without having to accept a clearly noticeable change in appearance in the case of such a change in the radiator sizes. The connection of these screw connections provided together with the central arrangement of the screw connections in the middle of the underside of the radiator with a control valve arranged laterally at the top of the radiator and with a radiator opening into the radiator plate collecting duct running below in the half of the longitudinal extension of the plate radiator opposite this control valve plate return connection, the heating medium entering a radiator plate inlet connection arranged at the control valve into the radiator plate in question, regardless of the radiator size, results in a largely uniform flow through the radiator plates, so that practically no reductions in heat emission, such as, for example, in the above-mentioned one-sided placement of flow connection and return connection are present. It is also possible at any time to use different radiator sizes than originally designed if the heat requirement changes, without having to change the supply lines. These advantages add to the favorable properties with regard to operation and control, which result from the arrangement of the radiator control valve on the top side of the radiator. The disadvantages of previously known radiators with centrally placed connecting screw connections, namely reduced heat emission and unfavorable regulation and operation of the valves, are also avoided.
Eine bevorzugte Ausführungsform des erfindungsgemäß ausge¬ bildeten Plattenradiators, bei der auch bei großen Radiator¬ längen eine sehr gleichmäßige Durchströmung gegeben ist, ist dadurch gekennzeichnet, daß der Radiatorplattenrücklaufanschluß an der dem Regelventil gegenüberliegenden Seite des Platten¬ radiators in den genannten unteren Radiatorplattensammelkanal einmünde .A preferred embodiment of the plate radiator designed according to the invention, in which there is a very uniform flow even with large radiator lengths, is characterized in that the radiator plate return connection opens into the lower radiator plate collecting duct on the side of the plate radiator opposite the control valve.
Eine weitere bevorzugte Ausführungsform, welche insbesondere dahingehend Vorteile bietet, daß im Bereich der Anschlußver¬ schraubungen ein Wärmeübergang vom zulaufenden auf das ablaufende Heizungsmedium hintangehalten wird, und weiter eine baulich sehr einfache Ausbildung der Anschlußverschraubungen erlaubt, ist dadurch gekennzeichnet, daß die Leitungsanschlüsse getrennt nebeneinander angeordnet sind.A further preferred embodiment, which offers advantages in particular in that a heat transfer from the incoming to the outgoing heating medium is prevented in the area of the connecting screw connections, and further one structurally very simple design of the screw connections allowed, is characterized in that the line connections are arranged separately next to each other.
Die vorzugsweise vorgesehene Ausführung der Verbindungsrohre aus Stahl ist sowohl hinsichtlich des Vermeidens galvanischer Korrosivwirkungen als auch hinsichtlich des weitgehenden Ver¬ meidensvon Unterschieden der thermischen Ausdehnung im Bereich des Radiators von Vorteil und schafft weiter auch die Möglich¬ keit im Bereich des Radiators mit einer einzigen Verbindungs¬ technologie, nämlich dem Schweißen, alle Verbindungen auf wirt¬ schaftliche Weise mit sehr guter Haltbarkeit herstellen zu können.The preferably provided design of the connecting pipes made of steel is advantageous both in terms of avoiding galvanic corrosive effects and in terms of largely avoiding differences in the thermal expansion in the area of the radiator and also creates the possibility in the area of the radiator with a single connection technology, namely welding, to be able to produce all connections in an economical manner with very good durability.
Im Interesse einer baulich weitgehenden Vereinfachung und einer Ersparnis an Montageschritten im Bereich der Anschlußver¬ schraubungen sowie im Interesse des Erzielens einer guten mechanischen Stabilität im Bereich der Anschlußverschraubungen, sowie einem Vermeiden des Vorsehens unterschiedlicher Metalle bis zu den Enden der Anschlußverschraubungen, kann man vorteil¬ haft eine Ausführungsform vorsehen, welche dadurch gekennzeich¬ net ist, daß die Anschlußverschraubungen mit Überwurfmutter- Rohrverbindungen ausgebildet sind, welche aus den Endabschnitten der vom Regelventil und vom Radiatorplattenrücklaufanschluß kommenden Verbindungsrohre und auf diese aufgefädelten Überwurf¬ muttern gebildet sind, wobei der Endabschnitt dieser Verbin¬ dungsrohre mit einem durch eine spanlos geformte radiale Ausfal¬ tung gebildeten Bund versehen ist, an dem die Überwurfmutter beim Aufschrauben auf ein an einer Zuleitung befindliches Gewindegegenstück zur Anlage kommt.In the interest of a structurally extensive simplification and a saving in assembly steps in the area of the connection screw connections and in the interest of achieving good mechanical stability in the area of the connection screw connections and avoiding the provision of different metals up to the ends of the connection screw connections, one can advantageously provide an embodiment which is characterized in that the connection screw connections are formed with union nut tube connections which are formed from the end sections of the connection tubes coming from the control valve and from the radiator plate return connection and union nuts threaded onto these, the end section of these connection tubes is provided with a collar formed by a non-cutting radial Ausfal¬ tion, on which the union nut comes to rest when screwing onto a threaded counterpart located on a feed line.
Es ist dabei für das Verbinden der Anschlußverschraubungen des Radiators mit den zum Aufstellungsort des Radiators führenden Zuleitungen von Vorteil, wenn man vorsieht daß, an den Verbindungsrohren auf den Bund folgend frei endende Rohrstutzen anschließen; diese Ausbildung ermöglicht eine gegenseitige Führung der Anschlußverschraubungen und der Zuleitungen beim Zusammenfügen und ergibt gleichzeitig auch eine gute Führung bzw. einen guten Sitz von Ringdichtungen welche in die Überwurfmutter-Rohrverschraubungen eingesetzt werden können.It is advantageous for the connection of the screw connections of the radiator with the leads leading to the installation site of the radiator if one provides that connecting pipe ends that follow the collar freely end; this design enables a mutual guidance of the screw connections and the supply lines when assembling and at the same time also results in a good guidance or a good fit of ring seals which can be inserted into the union nut tube fittings.
Eine weitere im Rahmen der Erfindung vorgesehene Ausfüh¬ rungsform des Plattenradiators ist dadurch gekennzeichnet, daß die Anschlußverschraubungen an einer zwei Leitungswege im konzentrischer Anordnung enthaltenden, verdrehbaren und lösbaren Kupplung gebildet sind, welche einen Radiatoranschlußteil, an den die Verbindungsrohre angeschlossen sind, und einen mit den Anschlußverschraubungen versehenen Zuleitungsanschlußteil auf¬ weist. Diese Ausführungsform bietet den Vorteil, daß der Radiator bei der Montage beliebig um die geometrische Achse der verdrehbaren Kupplung geschwenkt werden kann, was zum einen die Verlegung der Zuleitungen vereinfacht, da Lagetoleranzen der Zuleitungen durch die Möglichkeit des Verschwenkens des Radiators ausgeglichen werden können, und durch Schwenken des Radiators unter Umständen auch die Lage des Regelventils geändert werden kann, wenn der Wunsch oder die Notwendigkeit hierzu auftreten.Another embodiment of the plate radiator provided in the context of the invention is characterized in that the connecting screw connections are formed on a rotatable and releasable coupling containing two line paths in a concentric arrangement, which has a radiator connecting part to which the connecting pipes are connected and a supply connecting part provided with the connecting screw connections. This embodiment offers the advantage that the radiator can be pivoted around the geometric axis of the rotatable coupling during assembly, which on the one hand simplifies the laying of the supply lines, since positional tolerances of the supply lines can be compensated for by the possibility of pivoting the radiator, and by Swiveling the radiator under certain circumstances, the position of the control valve can be changed if the desire or the need for this occurs.
Der erfindungsgemäße Plattenradiator kann eine oder auch mehrere Radiatorplatten, welche miteinander in Durchflußver¬ bindung stehen, aufweisen, und es können die Radiatorplatten ohne oder mit Konvektionsblechen ausgeführt sein.The plate radiator according to the invention can have one or more radiator plates which are in flow connection with one another, and the radiator plates can be designed without or with convection plates.
