Description

Die Erfindung betrifft eine Infrarot-Heizung, insbesondere zum Beheizen von Hallen, Ställen und Gewächshäusern, gemäß dem Oberbegriff von Anspruch 1.Eine solche Infrarot-Heizung ist aus dem Dokument WO 01 42 716 bekannt.The invention relates to an infrared heater, in particular for heating halls, stables and greenhouses, according to the preamble of claim 1. Such an infrared heater is from the document WO 01 42 716 known.

Derartige Infrarot-Heizungen werden von der Anmelderin seit langem vertrieben, und umfassen ein in der Regel horizontal aufgehängtes, nach unten offenes Reflektorgehäuse, in welchem ein Strahlungsrohr aufgenommen ist, das durch einen Brenner, insbesondere durch einen Gasbrenner, mit einem Heizmedium beaufschlagt wird und die Wärme in Form von Infrarotlicht in die Halle abstrahlt. Der Brenner ist hierbei in einem kastenförmig ausgestalteten Brennergehäuse aufgenommen, welches stirnseitig an einem Ende des Strahlungsrohres außerhalb des Reflektorgehäuses angeordnet ist.Such infrared heaters are sold by the applicant for a long time, and include a generally horizontally suspended, downwardly open reflector housing in which a radiation tube is received, which is acted upon by a burner, in particular by a gas burner, with a heating medium and the Heat in the form of infrared light radiates into the hall. The burner is accommodated in a box-shaped burner housing, which is arranged on the front side at one end of the radiation tube outside the reflector housing.

Bei den bekannten Infrarot-Heizungen ergibt sich das Problem, dass die vom Strahlungsrohr durch die abgestrahlte Infrarotstrahlung zwischen dem Strahlungsrohr und der Unterseite des Reflektorgehäuses befindliche Luft sehr stark erhitzt wird und in unerwünschter Weise als Konvektionswärme über die unteren Kanten der Seitenwände des Reflektorgehäuses entweicht, von wo aus sie in dem zu beheizenden Raum aufsteigt und lediglich ungenutzt dazu dient, die Luft im oberen Bereich der Halle zu erwärmen.In the known infrared heaters there is the problem that the air from the radiant tube through the radiated infrared radiation between the radiant tube and the underside of the reflector housing is heated very strong and escapes in undesirable manner as convection heat over the lower edges of the side walls of the reflector housing, from where it rises in the room to be heated and serves only unused to heat the air in the upper part of the hall.

Um dem Energieverlust durch die entweichende Konvektionswärme zu entgegnen, wird in der EP 0162445 vorgeschlagen, den Brenner innerhalb des nach unten geöffneten und im Querschnitt glockenförmig ausgestalteten Reflektorgehäuses anzuordnen.In order to counteract the loss of energy by the escaping convection heat, in the EP 0162445 proposed to arrange the burner within the downwardly open and bell-shaped in cross-section reflector housing.

Weiterhin ist es aus der DE 3217948 C2 bekannt, das Reflektorgehäuse zweischalig auszugestalten und zwischen den beiden Schalen des Reflektorgehäuses einen Lüftungskanal vorzusehen, in dem die durch diesen geförderte Luft aufgrund der entstehenden Konvektionswärme erwärmt wird und im Anschluss daran für die Beheizung des Gebäudes zur Verfügung steht. Die hierbei der durch den Lüftungskanal hindurch geführten Luft zugeführte Wärmeenergie wird dabei zum Teil dem Strahlungsrohr entzogen, wodurch sich der abgestrahlte IR-Anteil verringert.Furthermore, it is from the DE 3217948 C2 known to design the reflector housing bivalve and provide a ventilation duct between the two shells of the reflector housing in which the air conveyed by this is heated due to the resulting convection heat and is subsequently available for the heating of the building. In this case, the guided through the ventilation duct air supplied heat energy is thereby partially withdrawn from the radiation tube, whereby the radiated IR component decreases.

Nachteilig bei den beiden zuvor genannten Strahlungsheizungen ist es hierbei weiterhin, dass die abgeführte Energie in ineffizienter Weise zur Erwärmung von Luft eingesetzt wird, und demgemäß nicht mehr als Strahlungsenergie zur Verfügung steht, mit welcher die Erwärmung von Objekten in einem größeren Abstand vom Strahlungsrohr in erheblich effizienterer Weise durch die Übertragung von Wärmestrahlung, d.h. von Infrarot-Strahlung, erfolgt. So wurde von der Anmelderin gefunden, dass bei den bisherigen Strahlungsheizungen der eingangs beschriebenen Art zwischen 15 % und 40 % der eingesetzten Energie in unerwünschter Weise als Konvektion entweichen.A disadvantage of the two radiation heaters mentioned above, it is also here that the dissipated energy is used in an inefficient manner for heating air, and accordingly no longer is available as radiant energy, with which the heating of objects at a greater distance from the radiant tube in considerably more efficient way by the transfer of heat radiation, ie of infrared radiation. Thus, it was found by the applicant that in the previous radiation heaters of the type described above escape between 15% and 40% of the energy used undesirably as convection.

Demgemäß ist es eine Aufgabe der vorliegenden Erfindung, eine Infrarot-Heizung zu schaffen, bei der die Energieverluste aufgrund von entstehender Konvektion weiter vermindert werden.Accordingly, it is an object of the present invention to provide an infrared heater in which energy losses due to incipient convection are further reduced.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale von Anspruch 1 gelöst.This object is achieved by the features of claim 1.

Weitere Merkmale der Erfindung sind in den Unteransprüchen enthalten.Further features of the invention are contained in the subclaims.

Gemäß der Erfindung umfasst eine Infrarot-Heizung, die insbesondere zum Beheizen von Hallen eingesetzt wird, einen Reflektor mit einem Reflektorgehäuse, in dem ein Infrarot-Strahlungsrohr verläuft, das durch einen Brenner, insbesondere einen Gasbrenner oder auch einen Ölbrenner, der bevorzugt außerhalb des Reflektorgehäuses angeordnet ist, mit Heißgas beaufschlagt wird.According to the invention, an infrared heater, which is used in particular for heating halls, comprises a reflector with a reflector housing, in which an infrared radiation tube passes through a burner, in particular a gas burner or an oil burner, preferably outside the reflector housing is arranged, is charged with hot gas.

Dem Brenner wird hierbei Frischluft über eine Luftzufuhröffnung zugeführt, und das Reflektorgehäuse besitzt einen im Querschnitt bevorzugt glockenförmigen Aufbau, mit wenigstens einer sich seitlich des Strahlungsrohres entlang erstreckenden Seitenwand, an deren Innenfläche die vom Strahlungsrohr abgegebene Infrarot-Strahlung, bei einem bevorzugt horizontal in einer Halle aufgehängten Reflektorgehäuse in Richtung zum Hallenboden reflektiert wird, um dort befindliche Objekte durch die Infrarot-Strahlung zu erwärmen.In this case, the burner is supplied with fresh air via an air supply opening, and the reflector housing has a preferably bell-shaped in cross section, with at least one sidewall extending laterally of the radiation tube, on the inner surface of which the infrared radiation emitted by the radiation tube, in a horizontal preferably in a hall Suspended reflector housing towards the Hall floor is reflected to heat objects located there by the infrared radiation.

Gemäß der Erfindung weist die Seitenwand im Bereich ihrer sich entlang des Strahlungsrohres erstreckenden Längskante und eventuell gleichzeitig das Reflektorgehäuse in einem oberhalb des Strahlungsrohres angeordneten zentralen Gehäuseabschnitt Absaugöffnungen auf, die über einen Luftabsaugkanal, der bevorzugt im Inneren der Seitenwand verläuft, jedoch alternativ auch als separate Leitung z.B. auf der Außenseite der Seitenwand geführt sein kann, mit der Luftzufuhröffnung des Brenners in Strömungsverbindung steht. Durch die Absaugöffnung hindurch wird die im Bereich der Innenseite des Reflektorgehäuses durch den Kontakt der Luftmoleküle mit der die Infrarot-Strahlung reflektierenden Innenwand des Reflektorgehäuses erwärmte Luft abgesaugt und dem Brenner als vorgewärmte Luft mit einer Temperatur von z.B. 150 °C bis 250 °C zugeführt. Da die in der vorgewärmten Luft enthaltene Wärmeenergie nicht zur Erwärmung von Luft im oberen Teil eines Raums oder Gebäudes sondern zur Aufheizung des Strahlungsrohres eingesetzt wird, ergibt sich durch die erfindungsgemäße Lösung beim Einsatz einer vorgegebenen Menge an Brennstoff welcher dem Brenner zugeführt wird, eine Erhöhung des Infrarot-Anteils um 3% bis 5%.According to the invention, in the region of its longitudinal edge extending along the radiation tube and possibly at the same time the reflector housing in a central housing section arranged above the radiation tube, the side wall has suction openings which extend via an air suction channel, which preferably runs in the interior of the side wall, but alternatively also as a separate conduit eg may be guided on the outside of the side wall, is in flow communication with the air supply opening of the burner. The air heated in the region of the inside of the reflector housing by the contact of the air molecules with the inner wall of the reflector housing reflecting the infrared radiation is sucked out through the suction opening and supplied to the burner as preheated air at a temperature of e.g. 150 ° C to 250 ° C supplied. Since the heat energy contained in the preheated air is not used for heating air in the upper part of a room or building but for heating the radiant tube, results from the inventive solution when using a predetermined amount of fuel which is supplied to the burner, an increase in Infrared component by 3% to 5%.

Ein weiterer Vorteil der erfindungsgemäßen Infrarot-Heizung besteht darin, dass es durch die Absaugung der erhitzten Luft im Bereich der Längskanten des Reflektorgehäuses nicht zu einer Abkühlung des Strahlungsrohres und damit zu einer unerwünschten Reduzierung des IR-Anteils kommt.Another advantage of the infrared heater according to the invention is that the extraction of the heated air in the region of the longitudinal edges of the reflector housing does not lead to a cooling of the radiation tube and thus to an undesired reduction of the IR component.

Ausführungsformen der Erfindung werden nachfolgend mit Bezug auf die Zeichnungen beschrieben.Embodiments of the invention will be described below with reference to the drawings.

Wie in Fig. 1 geneigt ist, umfasst eine erfindungsgemäße Infrarot-Heizung 1 ein Reflektorgehäuse 2 in welchem ein U-förmiges Strahlungsrohr 4 angeordnet ist, das durch einen Brenner 6, welcher an einem ersten Ende des Strahlungsrohres 4 angeordnet ist, mit Heizenergie beaufschlagt wird.As in Fig. 1 is inclined, an infrared heater 1 according to the invention comprises a reflector housing 2 in which a U-shaped radiation tube 4 is arranged, which is acted upon by a burner 6, which is arranged at a first end of the radiant tube 4, with heating energy.

Der Brenner 6 ist hierbei ein bekannter Gasbrenner oder Ölbrenner, dem ein nicht näher gezeigter Brennstoff, beispielsweise Gas oder Öl zugeführt wird, welches innerhalb des Strahlungsrohres 4 nach Vermischen mit Frischluft 10, die dem Brenner 6 über eine Luftzufuhröffnung 8 zugeführt wird, verbrannt wird und das Strahlungsrohr 4 auf seiner Außenseite hierbei auf eine Temperatur von im Mittel z.B. 280°C bis 350 °C oder mehr erwärmt.The burner 6 is in this case a known gas burner or oil burner to which a fuel not shown in detail, for example gas or oil is supplied, which is burned within the radiant tube 4 after mixing with fresh air 10, which is supplied to the burner 6 via an air supply opening 8, and the radiation tube 4 on its outside in this case to a temperature of on average, for example Heated to 280 ° C to 350 ° C or more.

Die vom Strahlungsrohr 4 abgestrahlte Infrarotstrahlung wird einerseits vom Strahlungsrohr 4 direkt in Richtung auf nicht näher gezeigte zu erwärmende Objekte abgestrahlt, oder nach einer Reflektion an den Innenseiten des Reflektorgehäuses 2, bzw. an einem oberhalb des Strahlungsrohres 4 angeordneten Zusatzreflektor 18 in Richtung der zu beheizenden Objekte reflektiert.The radiated from the radiant tube 4 infrared radiation is radiated on the one hand by the radiation tube 4 directly towards objects not to be heated, or after reflection on the insides of the reflector housing 2, or at a above the radiant tube 4 arranged additional reflector 18 in the direction to be heated Reflected objects.

Wie hierbei der Darstellung der Figuren 1 bis 3 weiterhin entnommen werden kann, besitzt das Reflektorgehäuse 2 eine im Querschnitt betrachtet glockenartige Form und erstreckt sich bevorzugt über die gesamte Länge des Strahlungsrohres 4 hinweg.As here the representation of the FIGS. 1 to 3 can be removed, the reflector housing 2 has a bell-shaped in cross-section shape and preferably extends over the entire length of the radiation tube 4 away.

Gemäß der Darstellung von Fig. 3 weist das Reflektorgehäuse 2 dabei wenigstens eine, bevorzugt jedoch zwei Seitenwände 12a, 12b auf, die sich in einem Winkel von beispielsweise 45° geneigt an einen zentralen Gehäuseabschnitt 14 anschließen, der bevorzugt horizontal angeordnet wird, wenn die erfindungsgemäße Infrarot-Heizung 1 über in den Figuren schematisch angedeutete Nivellierelemente 16 an der Decke eines zu beheizenden Gebäudes aufgehängt wird. Die Nivellierelemente 16 erlauben hierbei zum Beispiel durch ein in den Elementen vorgesehenes Rechts-Links-Gewinde, in welches entsprechende Gewindestangenabschnitte eingeschraubt werden, die an Aufhängungselementen wie Seilen oder Stangen befestigt sind, eine Veränderung der Länge der Aufhängungselemente, um die Neigung des Reflektorgehäuses 2, bzw. des Strahlungsrohres 4 zu verändern.As shown by Fig. 3 the reflector housing 2 in this case at least one, but preferably two side walls 12a, 12b, which adjoin one another at an angle of, for example, 45 ° to a central housing portion 14, which is preferably arranged horizontally, when the inventive infrared heater 1 in the Figures schematically indicated leveling elements 16 is suspended on the ceiling of a building to be heated. The leveling elements 16 in this case, for example, by a provided in the elements right-left thread, in which corresponding threaded rod sections are screwed, which are attached to suspension elements such as ropes or rods, a change in the length of the suspension elements to the inclination of the reflector housing 2, or of the radiation tube 4 to change.

Wie der Darstellung der Figuren 1 bis 3 weiterhin entnommen werden kann, wird die Frischluft 10 über mehrere Absaugöffnungen 20a, 20b abgesaugt. Diese sind erfindungsgemäß in der sich im Wesentlichen parallel zum Strahlungsrohr 4 erstreckenden Längskante 22a, 22b der zugehörigen Seitenwand 12a, 12b des Reflektorgehäuses angeordnet.As the representation of FIGS. 1 to 3 can still be removed, the fresh air 10 is sucked through a plurality of suction openings 20a, 20b. These are according to the invention in the substantially parallel to the radiation tube 4 extending longitudinal edge 22a, 22b of the associated side wall 12a, 12b of the reflector housing arranged.

Durch die Absaugöffnungen 20a, 20b wird die durch die Pfeile symbolisierte Luft 10 im Bereich der Längskanten 22a, 22b abgesaugt und im Anschluss daran durch einen der jeweiligen Absaugöffnung 20a, 20b zugeordneten Luftabsaugkanal 24a, 24b dem Brenner 6 als vorgewärmte Verbrennungsluft zugeführt, die z.B. eine Temperatur im Bereich von 150 bis 250 °C besitzt.Through the suction openings 20a, 20b, the air symbolized by the arrows 10 is sucked in the region of the longitudinal edges 22a, 22b and thereafter supplied through a respective suction opening 20a, 20b associated Luftabsaugkanal 24a, 24b the burner 6 as preheated combustion air, e.g. has a temperature in the range of 150 to 250 ° C.

Wie der Darstellung von Fig. 3 weiterhin entnommen werden kann, weist das Reflektorgehäuse 2 bevorzugt einen zweischaligen Aufbau auf, wobei die erste und zweite Seitenwand 12a, 12b des Reflektorgehäuses jeweils eine dem Strahlungsrohr 4 zugewandte Innenwand 26a, 26b und eine im Abstand zu dieser angeordnete Außenwand 28a, 28b besitzt, zwischen denen der Luftabsaugkanal 24a, 24b geformt ist. Der Abstand kann dabei z.B. 1 bis 5 cm betragen und durch nicht näher eingezeichnete Abstandshalter, wie z. B. Distanzhülsen oder Stege, erzeugt werden.Like the presentation of Fig. 3 can still be removed, the reflector housing 2 preferably has a two-shell construction, wherein the first and second side wall 12a, 12b of the reflector housing in each case one of the radiation tube 4 facing Inner wall 26a, 26b and a spaced apart therefrom outer wall 28a, 28b has, between which the Luftabsaugkanal 24a, 24b is formed. The distance can be, for example, 1 to 5 cm and not shown in detail spacers, such as. B. spacers or webs are generated.

Gemäß der Darstellung von Fig. 3 überragt die freie Kante 30a, 30b der jeweiligen Außenwand oder äußeren Schale 28a, 28b bei dieser Ausführungsform der Erfindung die sich entlang des Strahlungsrohres 4 erstreckende freie Kante 32a, 32b der Innenwand oder inneren Schale 26a, 26b um ein vorgegebenes Maß, beispielsweise um 1 bis 3 cm, um hierdurch im gewissen Sinne ein Barriere zu bilden, die ein ungehindertes Abströmen von erhitzter Luft an den Absaugöffnungen 20a, 20b vorbei unterbindet. Hierdurch kann der Wirkungsgrad der erfindungsgemäßen Infrarot-Heizung 1 in vorteilhafter Weise weiter gesteigert werden. Die Innenwand 26a, 26b ist auf der dem Strahlungsrohr 4 zugewandten Seite zur weiteren Steigerung des Wirkungsgrades bevorzugt mit einer Beschichtung versehen, die IR-Stralalung in dem jeweiligen Wellenlängenbereich reflektiert. Die Beschichtung kann beispielsweise eine Aluminiumbesehichtung sein.As shown by Fig. 3 In this embodiment of the invention, the free edge 30a, 30b of the respective outer wall or outer shell 28a, 28b projects beyond the free edge 32a, 32b of the inner wall or inner shell 26a, 26b extending along the radiation tube 4 by a predetermined amount, for example 1 to 3 cm, to thereby form in a sense a barrier that prevents unimpeded outflow of heated air past the suction openings 20a, 20b. In this way, the efficiency of the infrared heater 1 according to the invention can be further increased in an advantageous manner. The inner wall 26a, 26b is preferably provided on the side facing the radiation tube 4 to further increase the efficiency with a coating that reflects IR Stralalung in the respective wavelength range. The coating may be, for example, an aluminum dressing.

Wie in der Darstellung von Fig. 3 weiterhin durch die strichpunktierte Linie 34 angedeutet ist, liegen die freie Kante 30a, 30b der zugehörigen Außenwand 28a, 28b und die freie Kante 32a, 32b der zugehörigen Innenwand 26a, 26b des Reflektorgehäuses 2 bevorzugt auf einer Tangente 34 zu dem Strahlungsrohr 4. Beim Einsatz eines in den Darstellungen gezeigten U-fömigen Strahlungsrohr 4 verläuft die Tangente 34 hierbei genau genommen entlang des entfernt von der jeweiligen Längskante 22a, 22b liegenden Teilabschnitts des Strahlungsrohrs 4, wie dies in Fig. 3 am Beispiel der zweiten Seitenwand 12b des Reflektorgehäuses 2 angedeutet ist. Durch diese Ausgestaltung der Seitenwände ergibt sich der Vorteil, dass bei einem möglichst großen Abstrahlungsbereich für die Infrarotstrahlung die vom Strahlungsrohr 4 emittierte Infrarotstrahlung nicht direkt auf die Innenseite der Außenwand 28a, 28b auftrifft und diese erwärmt. Dadurch wird die abgesaugte Luft beim Kontakt mit diesem Wandabschnitt vor ihrem Eintritt in die Absaugöffnungen 20a, 20b nicht zusätzlich erhitzt, wodurch der Gesamtwirkungsgrad für den abgestrahlten IR-Anteil weiter gesteigert werden kann.As in the presentation of Fig. 3 Further indicated by the dotted line 34, the free edge 30a, 30b of the associated outer wall 28a, 28b and the free edge 32a, 32b of the associated inner wall 26a, 26b of the reflector housing 2 are preferably on a tangent 34 to the radiant tube 4. When used In the case of a U-shaped radiation tube 4 shown in the illustrations, the tangent 34 runs exactly along the section of the radiation tube 4 remote from the respective longitudinal edge 22a, 22b, as shown in FIG Fig. 3 is indicated by the example of the second side wall 12b of the reflector housing 2. As a result of this configuration of the side walls, there is the advantage that, with the largest possible radiation range for the infrared radiation, the infrared radiation emitted by the radiation tube 4 does not impinge directly on the inside of the outer wall 28a, 28b and heats the latter. As a result, the extracted air is not additionally heated in contact with this wall portion before it enters the suction openings 20a, 20b, whereby the overall efficiency of the radiated IR content can be further increased.

Gemäß einer Ausführungsform die nicht unter den Wertlaut der Ansprüche fällt, ist das Reflektorgehäuse 2 wie zuvor erwähnt - zweischalig aufgebaut, und es kann in jeder der beiden Seitenwände 12a, 12b eine einzelne Absaugöffnung vorgesehen sein, die sich bevorzugt über im Wesentlichen die gesamte Länge der jeweiligen Längskanten 22a, 22b des entsprechenden Seitenteils 12a,12b erstreckt.According to an embodiment which does not fall under the value of the claims, the reflector housing 2 is constructed as a two-shell, as mentioned above, and in each of the two side walls 12a, 12b a single suction opening may be provided which preferably extends over substantially the entire length of the respective longitudinal edges 22a, 22b of the corresponding side part 12a, 12b.

Hierbei ist es in Hinblick auf eine möglichst laminare Strömung und einen im Wesentlichen homogenen Druckverlaufinnerhalb der Luftabsaugkanäle 24a, 24b von besonderem Vorteil, wenn sich der Querschnitt der Absaugöffnungen 20a, 20b - vom Brenner 6 aus betrachtet - über im Wesentlichen die gesamte Länge des Reflektorgehäuses 2 hinweg bevorzugt stetig erweitert.In this case, it is of particular advantage with regard to a most laminar flow and a substantially homogeneous pressure curve within the air suction channels 24a, 24b, when the cross section of the suction openings 20a, 20b - viewed from the burner 6 - over substantially the entire length of the reflector housing second preferably continuously expanded.

Über die Länge der jeweiligen Längskante 22a, 22b der beiden Seitenwände 12a,12b hinweg ist eine Vielzahl von Absaugöffnungen 20a, 20b angeordnet, wie sie in der Seitendarstellung von Fig. 1 im Detail angedeutet sind.Over the length of the respective longitudinal edge 22a, 22b of the two side walls 12a, 12b across a plurality of suction openings 20a, 20b arranged, as shown in the side view of Fig. 1 are indicated in detail.

Jede der Absaugöffnungen 20a, 20b ist dabei bevorzugt über ein Verschlusselement 36, beispielsweise einen plättchenförmigen Schieber, in ihrer Größe veränderbar, um die Menge an durch die jeweilige Absaugöffnung 20a, 20b hindurch abgesaugter Luft 10 und die Strömungsverhältnisse innerhalb der Luftzufuhrkanäle 24a, 24b in Abhängigkeit von den jeweiligen Umgebungsbedingungen anpassen zu können.Each of the suction openings 20a, 20b is preferably variable in size via a closure element 36, for example a plate-shaped slide, by the amount of air 10 extracted through the respective suction opening 20a, 20b and the flow conditions within the air supply channels 24a, 24b to be able to adapt to the respective ambient conditions.

Wie der Darstellung von Fig. 1 und Fig. 2 weiterhin entnommen werden kann, laufen die Luftabsaugkanäle 24a, 24b in den Seitenwänden 12a, 12b bei der bevorzugten Ausführungsform der Erfindung in einer zentralen Sammelleitung 40 zusammen, die bevorzugt entlang des zentralen Gehäuseabschnitts 14 des Reflektorgehäuses 2 verläuft. Die Sammelleitung 40 geht dabei an der Außenseite des Reflektorgehäuses 2 in einen sich konisch oder dreieckförmig verjüngenden Stutzen 38 über, der durch einen senkrecht zur zentralen Sammelleitung 40 verlaufenden Umlenkabschnitt 42 mit der Luftzufuhröfnung 8 des Brenners 6 strömungsmäßig verbunden ist.Like the presentation of Fig. 1 and Fig. 2 Furthermore, in the preferred embodiment of the invention, the air exhaust ducts 24a, 24b in the side walls 12a, 12b converge in a central manifold 40, which preferably runs along the central housing section 14 of the reflector housing 2. The manifold 40 goes on the outside of the reflector housing 2 in a conically or triangular-tapered nozzle 38, which by a perpendicular to the central manifold 40 extending deflecting portion 42 with the Luftzufuhröfnung 8 of the burner 6 is fluidly connected.

Obgleich bei dieser Ausführungsform der Erfindung dem Brenner 6 neben der über die Absaugöffnung 20a, 20b und die zentrale Sammelleitung 40 zugeführten vorgewärmten Luft über eine nicht näher dargestellte Mischklappe oder ein Ventil gewünschten Falls zusätzlich auch kühlere Frischluft aus der Umgebung zugeführt werden kann, erfolgt die Zufuhr der Verbrennungsluft zur Erzielung eines maximalen Wirkungsgrades bevorzugt ausschließlich über die zentrale Sammelleitung 40.Although in this embodiment of the invention, the burner 6 in addition to the supplied via the suction port 20a, 20b and the central manifold 40 preheated air via a mixing flap, not shown, or a valve desired case in addition also cooler fresh air from the environment can be supplied, the supply takes place the combustion air to achieve maximum efficiency preferably exclusively via the central manifold 40th

Um den Wirkungsgrad noch weiter zu erhöhen, kann es hierbei vorgesehen sein, dass der oder die Luftabsaugkanäle 24a, 24b sowie bevorzugt auch die zentrale Sammelleitung 40 und der Stutzen 38 sowie der Umlenkabschnitt 42 mit einem thermisch isolierenden Werkstoff, beispielsweise mit Steinwolle oder Glaswolle oder einem anderen thermisch beständigen Werkstoff nach außen hin isoliert werden, um eine Abstrahlung von Wärmeenergie der über die Absaugöffnungen 20a, 20b angesaugten vorgewärmten Luft 10 bei ihrem Weg durch die Luftabsaugkanäle 24a, 24b sowie die zentrale Sammelleitung 40, den Stutzen 38 und den Umlenkabschnitt 42 nach Möglichkeit zu vermeiden, bzw. so gering wie möglich zu halten. Das zuvor erwähnte Isolationsmaterial ist in den Zeichnungen aus darstellungstechnischen Gründen nicht näher gezeigt.In order to increase the efficiency even further, it may be provided that the one or more Luftabsaugkanäle 24a, 24b and preferably also the central manifold 40 and the nozzle 38 and the deflection 42 with a thermally insulating material, such as rock wool or glass wool or a other thermally resistant material to be insulated to the outside to radiation of heat energy of the sucked through the suction openings 20a, 20b preheated air 10 on its way through the Luftabsaugkanäle 24a, 24b and the central manifold 40, the nozzle 38 and the deflection section 42 as far as possible to avoid or keep as small as possible. The aforementioned isolation material is not shown in detail in the drawings for illustrative purposes.

Ebenso kann es im Hinblick auf einen optimalen Wirkungsgrad von Vorteil sein, wenn die Seitenwände 12a, 12b sowie auch der zentrale Gehäuseabschnitt 14 auf der Innenseite sowie gegebenenfalls auch auf der Außenseite der Innenwände 26a, 26b und/oder der Innenseite der Außenwände 28a, 28b mit einem thermischen Isolierwerkstoff besetzt sind, um die durch Konvektion entstehenden Energieverluste die so gering wie möglich zu halten.It may also be advantageous in terms of optimum efficiency when the side walls 12a, 12b as well as the central housing portion 14 on the inside and possibly also on the outside of the inner walls 26a, 26b and / or the inside of the outer walls 28a, 28b with a thermal insulating material are occupied in order to keep the convective energy losses as low as possible.

Gemäß der in Fig. 4 gezeigten weiteren Ausführungsform der Erfindung, können zusätzlich zu den Öffnungen in den Seitenwänden des Reflektorgehäuses 2 eine oder mehrere Absaugöffnungen 102a in einem oberhalb des Strahlungsrohres 4 angeordneten Gehäuseabschnitt, insbesondere dem zentralen Gehäuseabschnitt 14 angeordnet sein.According to the in Fig. 4 shown further embodiment, in addition to the openings in the side walls of the reflector housing 2, one or more suction openings 102a in one above the radiant tube 4th arranged housing portion, in particular the central housing portion 14 may be arranged.

Wie die Anmelderin gefunden hat, kann durch den Einsatz von Luftabsaugöffnungen 120a im Bereich unmittelbar oberhalb des Strahlungsrohres 4 ein Teil der oberhalb des Strahlungsrohres befindlichen Luft abgesaugt und dem Brenner 6 als vorgewärmte Luft wieder zugeführt werden, um den Gesamt-Strahlungswirkungsgrad weiter zu steigern. Dies ist nach Auffassung der Anmelderin darauf zurück zu führen ist, dass die den Wirkungsgrad steigernde Vorwärmung der dem Brenner zugeführten Luft in diesem Bereich in erster Linie durch einen Kontakt derselben mit der Oberseite des Strahlungsrohres 4 erfolgt, welches hierdurch geringfügig abgekühlt wird und einen gegenüber der Unterseite des Strahlungsrohres reduzierten Anteil an Infrarotstrahlung abstrahlt. Allerdings fällt die lokale Abkühlung und die damit einhergehend Verringerung des IR-Strahlungsanteils auf der Oberseite des Strahlungsrohres 4 nicht weiter ins Gewicht, da ein gewisser Teil der von der Oberseite des Rohres emittierten IR-Strahlung nach ihrer Reflexion am Reflektorgehäuse oberhalb des Strahlungsrohres wieder auf das Strahlungsrohr auftrifft und dadurch nicht - wie gewünscht - als IR-Strahlung in den untenliegenden Raum abgestrahlt wird, sondern das Rohr an der Oberseite wieder aufheizt.As the Applicant has found, the use of Luftabsaugöffnungen 120a in the area immediately above the radiation tube 4, a portion of the air located above the radiant tube sucked off and the burner 6 are returned as preheated air to further increase the overall radiation efficiency. This is, in the Applicant's view, due to the fact that the efficiency-increasing preheating of the air supplied to the burner in this area is primarily due to contact thereof with the top of the radiant tube 4, which is thereby slightly cooled and one opposite to the first Bottom of the radiation tube radiates reduced proportion of infrared radiation. However, the local cooling and the concomitant reduction of the IR radiation fraction on the upper side of the radiant tube 4 are no longer significant since some of the IR radiation emitted by the upper side of the tube, after its reflection on the reflector housing above the radiant tube, returns to the Radiation tube impinges and thereby not - as desired - is radiated as IR radiation in the underlying space, but reheats the tube at the top again.

Der zuvor beschriebene Effekt tritt insbesondere dann verstärkt auf, wenn die Absaugöffnungen 120a ausschließlich an dem entfernt vom Brenner 6 angeordneten Ende des Reflektorgehäuses 2 in den zentralen Gehäuseabschnitt 14 eingebracht sind, bevorzugt in den Bereich des U-förmigen Abschnitts, in dem das Strahlungsrohr 4 umgelenkt wird. Obgleich die Absaugung der Luft prinzipiell auch ausschließlich über die im zentralen Gehäuseabschnitt 14 angeordneten Absaugöffnungen 120a erfolgen kann (Eine solche Ausführungsform fällt jedoch nicht unter den Wertlaut der Ansprüche.), lässt sich der dem Brenner 6 zugeführte vorgewärmte Luftstrom zur Optimierung des Wirkungsgrades dadurch sehr leicht an die jeweiligen Verhältnisse anpassen, da zusätzlich Luftabsaugöffnungen 20a, 20b in den Längskanten 22a, 22b des Reflektorgehäuses 2 vorgesehen sind, deren Größe über Verschlusselemente 36 veränderbar ist. Mit Ausnahme der Öffnungen 120a entspricht diese Ausführungsform der Erfindung vom grundsätzlichen Aufbau her im Wesentlichen der Ausführungsform der Figuren 1 bis 3.The effect described above occurs in particular when the suction openings 120a are introduced exclusively at the end of the reflector housing 2 arranged away from the burner 6 into the central housing section 14, preferably into the region of the U-shaped section in which the radiation pipe 4 is deflected becomes. Although the extraction of the air in principle can be done exclusively via the arranged in the central housing section 14 exhaust 120a (Such embodiment is not, however, under the value of the claims.), The burner 6 supplied preheated air flow to optimize the efficiency thereby very easy adapt to the respective conditions, since in addition air suction openings 20a, 20b are provided in the longitudinal edges 22a, 22b of the reflector housing 2, whose size is variable via closure elements 36. With the exception of the openings 120a, this embodiment of the invention basically corresponds to the embodiment of FIG FIGS. 1 to 3 ,
