Description

Die Erfindung bezieht sich auf einen Heizkörper, insbesondere Heizungsradiator, dem die abzugebende Wärmeenergie durch ein flüssiges Heizmedium, welches den Heizkörper durchfließt, zugeführt wird, wobei im Fließweg des Heizmedizums im Bereich des Heizkörpers eine Überdruckturbine vorgesehen ist, in der das Heizmedium über Strömungsleitflächen einem Schaufeln tragenden Laufrad zufließt, und am Heizkörper ein von dieser Turbine in Drehung versetzter Lüfter angeordnet ist, der die über den Heizkörper führende Luftströmung intensiviert und damit die Wärmeabgabe der Heizkörperflächen vergrößert.The invention relates to a radiator, in particular a heating radiator, to which the heat energy to be given off is fed through a liquid heating medium which flows through the radiator, an overpressure turbine being provided in the heating medium flow path in the region of the radiator, in which the heating medium is a blade via flow guide surfaces flowing impeller flows, and on the radiator a fan rotated by this turbine is arranged, which intensifies the air flow over the radiator and thus increases the heat dissipation of the radiator surfaces.

Ein Heizkörper vorgenannter Art, der als gegen Abstrahlung weitgehend isolierter Konvektor ausgebildet ist, ist aus der CH-A-411 285 bekannt. Es ist bei diesem bekannten Heizkörper die Turbine mit fix eingebauten Strömungsflächen, über die das Medium dem Laufrad zufließt, versehen, wobei auch die Möglichkeit in Betracht gezogen ist, durch Ablenken eines Teiles der auf das Laufrad gerichteten Strömung, was z. B. durch Verschieben des Laufrades vorgenommen werden kann, die Antriebsströmung des Laufrades herabzumindern. Es ist bei diesem bekannten Konzept eine verhältnismäßig starke Strömung des Heizmediums erforderlich, um einen ausreichenden Antrieb des Lüfters zu erhalten.A radiator of the aforementioned type, which is designed as a convector largely insulated against radiation, is known from CH-A-411 285. It is in this known radiator, the turbine with built-in flow areas through which the medium flows to the impeller, provided, the possibility is also considered by deflecting a portion of the flow directed to the impeller, which z. B. can be made by moving the impeller to reduce the drive flow of the impeller. In this known concept, a relatively strong flow of the heating medium is required in order to obtain sufficient fan drive.

Man trachtet nun in neuerer Zeit bei Heizungsanlagen mit kleinen Rohrdimensionen das Auslangen zu finden, und es ist der Wirkungsgrad der Umwälzpumpen, insbesondere bei Kleinanlagen, eher gering. Damit kann in den meisten Fällen an den Heizkörpern nur eine mäßige Strömung des Heizmediums erzielt werden, wobei überdies an den verschiedenen Heizkörpern einer Heizungsanlage unterschiedliche Strömungsverhältnisse vorliegen können.In recent times, attempts have been made to find a solution for heating systems with small pipe dimensions, and the efficiency of the circulation pumps, especially in small systems, is rather low. In most cases, this means that only a moderate flow of the heating medium can be achieved on the radiators, although different flow conditions can also be present on the various radiators in a heating system.

Es ist ein Ziel der Erfindung, einen Heizkörper eingangs erwähnter Art zu schaffen, bei dem auf einfache Weise eine Abstimmung des Antriebes für den Lüfter an die jeweils vorliegenden Verhältnisse, und zwar sowohl hinsichtlich der Umlaufströmung des Heizmediums im Heizsystem als auch hinsichtlich der Lage des jeweiligen Heizkörpers im Heizsystem und hinsichtlich der jeweils gewünschten Lüfterwirkung vorgenommen werden kann.It is an object of the invention to provide a radiator of the type mentioned at the beginning, in which the drive for the fan is easily matched to the prevailing conditions, both with regard to the circulating flow of the heating medium in the heating system and with regard to the position of the respective one Radiator in the heating system and with regard to the desired fan effect can be made.

Der erfindungsgemäße Heizkörper eingangs erwähnter Art ist dadurch gekennzeichnet, daß dem Laufrad der Turbine ein mit Strömungsleitflächen versehener und die Strömung des Heizmediums dirigierender austauschbarer Einsatz vorgeschaltet ist.The radiator according to the invention of the type mentioned at the outset is characterized in that the turbine impeller is preceded by an interchangeable insert provided with flow guide surfaces and directing the flow of the heating medium.

Durch die erfindungsgemäß vorgesehene Ausbildung kann der vorstehend angeführten Zielsetzung gut entsprochen werden. Durch die Austauschbarkeit des mit Strömungsleitflächen versehenen Einsatzes kann auf einfache Weise eine Anpassung der Turbinenleistung und des Turbinenwirkungsgrades an die jeweils vorliegenden Strömungsverhältnisse und eine gute Ausnützung der Strömung für den Antrieb des Lüfters erzielt werden.With the training provided according to the invention, the above-mentioned objective can be met well. Due to the interchangeability of the insert provided with flow control surfaces, an adaptation of the turbine power and the turbine efficiency to the prevailing flow conditions and a good utilization of the flow for the drive of the fan can be achieved in a simple manner.

Eine vorteilhafte Ausführungsform für Einrohrheizungen erhält man, wenn man den Hydraulikmotor in einer Bypass-Strecke anordnet, da man auf diese Weise für den Hydraulikmotor einerseits eine verhältnismäßig groß Durchströmung zur Verfügung hat und andererseits durch den Strömungswiderstand des Hydraulikmotors von selbst die erforderliche Drosselung der Bypass-Strecke, die ja die Durchströmung des Heizkörpers einer Einrohrheizung ergibt, erhält. Gewünschtenfalls kann man auch bei einer normalen Zweirohrverteilung des Heizmediums einer Heizungsanlage den Hydraulikmotor dem jeweiligen Heizkörper parallel schalten, was insbesondere dann vorteilhaft ist, wenn in der betreffenden Heizungsanlage ein großes Umlaufvolumen an Heizmedium bei verhältnismäßig niederem Druck zur Verfügung steht.An advantageous embodiment for one-pipe heaters is obtained if the hydraulic motor is arranged in a bypass section, since on the one hand a relatively large throughflow is available for the hydraulic motor and on the other hand the required throttling of the bypass by the flow resistance of the hydraulic motor. Distance, which results in the flow through the radiator of a one-pipe heater. If desired, even with a normal two-pipe distribution of the heating medium of a heating system, the hydraulic motor can be connected in parallel with the respective radiator, which is particularly advantageous if a large circulation volume of heating medium is available at relatively low pressure in the heating system in question.

Zur Placierung des Lüfters am Heizkörper stehen eine Reihe von Möglichkeiten offen, wobei natürlich einerseits die Form der wärmeabgebenden Flächen des betreffenden Heizkörpers und die sich ergebende natürliche Konvektion und andererseits die Lage des Hydraulikmotors und die Gegebenheiten der Antriebsverbindung vom Hydraulikmotor zum Lüfter in Betracht zu ziehen sind. Eine vorteilhafte Ausführungsform ergibt sich dabei, wenn man vorsieht, daß der Heizkörper als Plattenradiator ausgebildet ist und der Lüfter im Bereich des unteren Randes der Radiatorplatte bzw. der Radiatorplatten angeordnet ist. Es kann so auch eine gute Zugänglichkeit der Turbine für den Austausch des mit Strömungsleitflächen versehenen Einsatzes erzielt werden. Es ergibt sich dabei weiter eine kompakte, platzsparende Ausbildung, wenn man vorsieht, daß der Plattenradiator aus mindestens zwei Radiatorplatten besteht und der Lüfter im Zwischenraum zwischen den Radiatorplatten im Bereich des unteren Randes dieser Platten angeordnet ist.There are a number of options for placing the fan on the radiator.Of course, on the one hand, the shape of the heat-emitting surfaces of the radiator in question and the resulting natural convection, and on the other hand, the position of the hydraulic motor and the conditions of the drive connection from the hydraulic motor to the fan must be taken into account . An advantageous embodiment is obtained if it is provided that the heating element is designed as a plate radiator and the fan is arranged in the region of the lower edge of the radiator plate or the radiator plates. Good accessibility of the turbine for the exchange of the insert provided with flow control surfaces can also be achieved in this way. There is also a compact, space-saving design if it is provided that the plate radiator consists of at least two radiator plates and the fan is arranged in the space between the radiator plates in the region of the lower edge of these plates.

Außer dem bevorzugten Anblasen kommt auch ein Absaugen von Luft vom Heizkörper mit Hilfe des Lüfters in Frage.In addition to the preferred blowing, the fan can also be used to extract air from the radiator.

Hinsichtlich des Lüfters selbst ist es in vielen Fällen, z. B. für ein Angringen des Lüfters im Bereich des unteren Randes des Heizkörpers oder im Zwischenraum zwischen den einzelnen Platten eines Plattenheizkörpers, von Vorteil, wenn der Lüfter ein sogenannter Querstromlüfter ist. Man kann aber als Lüfter auch einen Axialventilator vorsehen.Regarding the fan itself, it is in many cases, e.g. B. for mounting the fan in the area of the lower edge of the radiator or in the space between the individual plates of a plate heater, advantageous if the fan is a so-called cross-flow fan. However, an axial fan can also be provided as a fan.

Die Erfindung wird nun anhand in der Zeichnung dargestellter Beispiele weiter erläutert. In der Zeichnung zeigt:

  • Fig. 1 eine Ausführungsform eines erfindungsgemäß ausgebildeten Heizkörpers in einem lotrechten Schnitt,
  • Fig. 2 diesen Heizkörper in einem waagrecht geführten Schnitt gemäß der Linie 11-11 in Fig. 1,
  • Fig. 3 eine für einen erfindungsgemäß ausgebildeten Heizkörper vorgesehene Antriebsverbindung vom Hydraulikmotor zum Lüfter, und
  • Fig. 4 eine weitere Ausbildung einer derartigen Antriebsverbindung.
The invention will now be explained with reference to examples shown in the drawing. The drawing shows:
  • 1 shows an embodiment of a radiator designed according to the invention in a vertical section,
  • 2 this radiator in a horizontally guided section along the line 11-11 in Fig. 1,
  • 3 shows a drive connection from the hydraulic motor to the fan provided for a radiator designed according to the invention, and
  • Fig. 4 shows a further embodiment of such a drive connection.

Die in den Fig. 1 und 2 dargestellte Ausführungsform eines erfindungsgemäßen Heizkörpers weist zwei Radiatorplatten 1, 2 auf, die, wie an sich üblich, über Verbindungsrohre zusammengeschlossen sind. Es ist ein derartiges Verbindungsrohr 3 dargestellt, und es ist in diesem Verbindungsrohr ein Hydraulikmotor 4 placiert, der zum Antrieb eines Lüfters 5 dient. Dieser Lüfter 5 ist als Querstromlüfter mit einer Lüfterwalze 6 und Strömungsleitflächen 7, 8 ausgebildet und im Bereich des unteren Randes des Heizkörpers im Zwischenraum 9 zwischen den beiden Radiatorplatten 1, 2 angeordnet. Diese Lüfterwalze fördert bei Rotation Umgebungsluft im Sinne der Pfeile 10 aus dem unter dem Heizkörper gelegenen Bereich durch den Zwischenraum 9 zwischen den beiden Radiatorplatten 1, 2 nach oben und intensiviert damit die Wärmeabgabe von dieser Radiatorplatte durch Konvektion. Man kann dabei gewünschtenfalls im Zwischenraum 9 an den Radiatorplatten in üblicher Weise auch Konvektionsbleche 11, 12 anordnen.The embodiment of a radiator according to the invention shown in FIGS. 1 and 2 has two radiator plates 1, 2 which, as is conventional, are connected via connecting pipes. Such a connecting pipe 3 is shown, and a hydraulic motor 4 is placed in this connecting pipe, which serves to drive a fan 5. This fan 5 is designed as a cross-flow fan with a fan roller 6 and flow guide surfaces 7, 8 and is arranged in the area of the lower edge of the radiator in the space 9 between the two radiator plates 1, 2. During rotation, this fan roller conveys ambient air in the sense of arrows 10 from the area located under the radiator through the space 9 between the two radiator plates 1, 2 and thus intensifies the heat dissipation from this radiator plate by convection. If desired, convection plates 11, 12 can also be arranged in the space 9 on the radiator plates in the usual way.

Der zum Antrieb des Lüfters 5 vorgesehene Hydraulikmotor 4 ist in Form einer Überdruckturbine und zwar im speziellen in Form einer Propellerturbine mit einem Laufrad 14 ausgebildet, und es ist dieses Laufrad auf einer Welle 15 gelagert, welche auch die Antriebsverbindung zur Lüfterwalze 6 herstellt. Die Welle 15 führt mit genauer leicht gängiger Passung durch einen Lagerkörper 16, wobei durch diese Passung auch die erforderliche Abdichtung gegen einen Austritt von Heizmedium, welches den Hydraulikmotor 4 durchfließt, geschaffen ist. Das Laufrad 14 des als Propellerturbine ausgebildeten Hydraulikmotors ist von einer Ringwand 17 umgeben, welche unmittelbar auf den Zuleitungsanschlußstutzen 18 des Heizkörpers folgt. In diesem Zuleitungsanschluß wird bei der üblichen Montage des Heizkörpers das Anschlußrohr 20 eingeschraubt. Dem Laufrad 14 ist ein die Strömung des Heizmediums dirigierender Verdrängerkörper 21 vorgeordnet, der Strömungsleitflächen 22 trägt, welche den Winkel, unter dem die Strömung auf die Schaufeln 23 des Laufrades 14 trifft, bestimmen. Der Verdrängerkörper 21 mit den Strömungsleitflächen 22 ist austauschbar vorgesehen, wobei man durch verschiedene Ausbildung der Strömungsleitflächen 22 eine dem jeweiligen Einsatzfall entsprechende Anpassung an die Gegebenheiten der Strömung des Heizmediums und an die Gegebenheiten des Lüfters 5 erzielen kann.The hydraulic motor 4 provided for driving the fan 5 is designed in the form of an overpressure turbine, specifically in the form of a propeller turbine with an impeller 14, and this impeller is mounted on a shaft 15, which also establishes the drive connection to the fan roller 6. The shaft 15 leads through a bearing body 16 with a precise, easily fitting fit, this fitting also providing the required seal against the escape of heating medium which flows through the hydraulic motor 4. The impeller 14 of the hydraulic motor, which is designed as a propeller turbine, is surrounded by an annular wall 17, which immediately follows the inlet connecting piece 18 of the radiator. The connecting tube 20 is screwed into this supply line connection during the usual assembly of the radiator. Upstream of the impeller 14 is a displacer 21 which directs the flow of the heating medium and which carries flow guide surfaces 22 which determine the angle at which the flow impinges on the blades 23 of the impeller 14. The displacer body 21 with the flow guide surfaces 22 is provided interchangeably, and by different design of the flow guide surfaces 22, an adaptation to the conditions of the flow of the heating medium and to the conditions of the fan 5 can be achieved according to the respective application.

Gewünschtenfalls kann man den Hydraulikmotor auch in Form einer Francis-Turbine ausbilden, wobei sowohl eine axiale Anspeisung, wie bei der Propellerturbine nach Fig. 2, als auch eine Spiralanspeisung in Betracht kommt. Da die Spiralanspeisung einer Francis-Turbine einen außen liegenden Betriebsmittelzufluß aufweist, der über einen dem Laufradumfang folgenden Kanal erfolgt und die Abströmung des Betriebsmittels vom Laufrad axial stattfindet, eignet sich eine solche Ausführungsform insbesondere für Heizkörper, bei denen analog den Fig. 1 und 2 eine waagrecht verlaufende Antriebswelle des Lüfters vorliegt und der Zuleitungsanschluß des Heizkörpers dazu senkrecht ausgerichtet ist, also einen lotrechten Verlauf hat. Auch bei der Ausbildung des Hydraulikmotors in Form einer Francis-Turbine sind die stehenden Strömungsleitflächen der Turbine in Form eines austauschbaren Einsatzes ausgeführt.If desired, the hydraulic motor can also be designed in the form of a Francis turbine, both an axial feed, as in the case of the propeller turbine according to FIG. 2, and a spiral feed. Since the spiral feed of a Francis turbine has an external inflow of operating fluid that takes place via a channel following the impeller circumference and the outflow of the operating fluid takes place axially, such an embodiment is particularly suitable for radiators in which, analogously to FIGS horizontally running drive shaft of the fan is present and the supply connection of the radiator is oriented perpendicular to it, that is to say it has a vertical course. When the hydraulic motor is designed in the form of a Francis turbine, the standing flow guide surfaces of the turbine are designed in the form of an exchangeable insert.

Die Strömung des Heizmediums von der Zuleitung des Heizkörpers durch die Propellerturbine 4 und weiter in die Radiatorplatten 1, 2 ist in Fig. 2 durch die Pfeile 25 angedeutet.The flow of the heating medium from the supply line of the radiator through the propeller turbine 4 and further into the radiator plates 1, 2 is indicated in FIG. 2 by the arrows 25.

Bei der in Fig. 3 dargestellten Variante der Antriebsverbindung vom Hydraulikmotor zum Lüfter eines erfindungsgemäß ausgebildeten Heizkörpers ist die Welle 15, welche das Laufrad 14 einer Turbine mit einem Läufer 26 des Lüfters verbindet, mit leichtem Laufspiel in einem Lager 27 gelagert, welches den vom Heizmedium erfüllten Raum 28, in dem sich die Turbine befindet, von der freien Umgebung 29 des Heizkörpers trennt, und es ist zur Abdichtung in das Lager 27 eine Ringdichtung 30 eingefügt, welche z. B. in Form eines O-Ringes oder eines Simmer-Ringes ausgebildet sein kann.In the variant of the drive connection from the hydraulic motor to the fan of a radiator designed according to the invention, which is shown in FIG. 3, the shaft 15, which connects the impeller 14 of a turbine to a rotor 26 of the fan, is mounted with a slight play in a bearing 27, which supports the heating medium fulfilled space 28, in which the turbine is located, separates from the free environment 29 of the radiator, and an annular seal 30 is inserted for sealing in the bearing 27, which z. B. can be in the form of an O-ring or a Simmer ring.

Bei der in Fig. 4 dargestellten Variante ist die vom Hydraulikmotor 4 zum Lüfter 5 führende Antriebsverbindung durch eine dauermagnetische Kupplung gebildet. Der treibende Kupplungsteil ist dabei durch einen auf der Welle 15 des Läufers 14 der Turbine angeordneten Dauermagneten 31 gebildet, und es ist der getriebene Kupplungsteil in Form eines Bügels 32 aus ferromagnetischem Material, insbesondere weichem Eisen, realisiert. Dieser Bügel 32 ist auf einer Welle 33, die mit dem walzenförmigen Rotor 6 des Lüfters 5 verbunden ist, angebracht. Der treibende Kupplungsteil 31 und der getriebene Kupplungsteil 32 sind voneinander durch eine flüssigkeitsdichte Wand in Form eines Bechers 34 getrennt. Der Becher 34 besteht aus einem nicht magnetisierbaren Material, welches einen die Entstehung von Wirbelströmen weitgehend vermeidenden Wert seines elektrischen Widerstandes hat. Die Mitnahme des getriebenen Kupplungsteiles vom treibenden Kupplungsteil her erfolgt dabei über die Wirkung der magnetischen Kraftlinien 35 des Magneten 31, für die der Bügel 32 ein Schließjoch darstellt.In the variant shown in FIG. 4, the drive connection leading from the hydraulic motor 4 to the fan 5 is formed by a permanent magnetic coupling. The driving coupling part is formed by a permanent magnet 31 arranged on the shaft 15 of the rotor 14 of the turbine, and the driven coupling part is realized in the form of a bracket 32 made of ferromagnetic material, in particular soft iron. This bracket 32 is mounted on a shaft 33 which is connected to the roller-shaped rotor 6 of the fan 5. The driving coupling part 31 and the driven coupling part 32 are separated from one another by a liquid-tight wall in the form of a cup 34. The cup 34 is made of a non-magnetizable material which has a value of its electrical resistance that largely avoids the formation of eddy currents. The drive of the driven coupling part from the driving coupling part takes place via the action of the magnetic lines of force 35 of the magnet 31, for which the bracket 32 represents a closing yoke.

Erfindungsgemäß ausgebildete Heizkörper können auch über die Anspeisung mit Heizmedium in ihrer Wärmeabgabe gesteuert werden. Es ergibt sich dabei auch die Möglichkeit, durch Änderung der Umlaufmenge des Heizmediums ohne Veränderung der Zulauftemperatur des Heizmediums die Wärmeabgabe der Heizkörper zu steuern, da mit einer Änderung der Umlaufmenge des Heizmediums bzw. des Pumpendrucks im System die Drehzahl der Turbinen in den Heizkörpern einer Anlage und damit die die Wärmeabfuhr von den Heizkörpern wesentlich bestimmende Lüfterwirkung verändert werden kann. Diese Veränderung kann auch mittels Ventilsteuerung für einzelne Heizkörper individuell vorgenommen werden, z. B. unter Verwendung von Thermostatventilen.Radiators designed according to the invention can also be controlled in terms of their heat emission via the supply with heating medium. There is also the possibility of controlling the heat output of the radiators by changing the circulating quantity of the heating medium without changing the inlet temperature of the heating medium, since changing the circulating quantity of the heating medium or the pump pressure in the system changes the speed of the turbines in the radiators of a system and thus the fan effect, which essentially determines the heat dissipation from the radiators, can be changed. This change can also be made individually for individual radiators by means of valve control, e.g. B. using thermostatic valves.
