Description

Die Erfindung betrifft einen Heizkörper gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a radiator according to the preamble of claim 1.

Seit vielen Jahren haben sich derartige z.B. auf Rollen bewegbare, steckdosenanschlußtaugliche Raumheizradiatoren mit elektrischer Widerstandsheizeinrichtung, insbesondere Heizstäben bzw. leicht austauschbaren Heizpatronen als flexibel einsetzbare Heizgeräte für Übergangsjahreszeiten, Kälteperioden in der wärmeren Jahreszeit und als Zusatzheizungen hervorragend bewährt. Derartige Heizkärper sind z.B. aus der EP-A-292441 und EP-A 114158 bekannt.For many years, e.g. Room heating radiators with electrical resistance heating devices that can be moved on rollers and are suitable for plug sockets, especially heating elements or easily replaceable heating cartridges, have proven themselves extremely well as flexible heating devices for transitional seasons, cold periods in the warmer season and as additional heaters. Such radiators are e.g. known from EP-A-292441 and EP-A 114158.

Einen gewissen Nachteil stellen die infolge Einsatzes elektrischer Energie relativ hohen Kosten solcher Heizgeräte dar und es geht daher die Tendenz in die Richtung, die Heizwirkung energiesparend zu erhöhen, indem eine möglichst hohe Differenz zwischen der Oberflächentemperatur der Radiator-Rippen im Bereich von deren Ölfüllung und der jeweils herrschenden Raumtemperatur angestrebt wird.A certain disadvantage is the relatively high cost of such heaters due to the use of electrical energy and there is therefore a tendency to increase the heating effect in an energy-saving manner by making the greatest possible difference between the surface temperature of the radiator fins in the area of their oil filling and the prevailing room temperature is sought.

So entspricht es dieser Tendenz, z.B. bei einer Raumtemperatur von 25°C, eine Oberflächentemperatur der heißesten Zonen der Radiatorglieder von z.B. 110°C zu erreichen, was einer (gemäß EG-Norm derzeit vorgegebenen) Temperaturdifferenz von 85°C entspricht. Gleichzeitig mit den Energieeinsparungen wird so eine verbesserte Konvektion und damit ein angenehmes Raumklima erreicht. Zusätzlich ist der Vorteil gegeben, bei gleicher Wärmeabgabeleistung die Zahl der Radiatorglieder zu verringern, was Materialeinsparungen bringt und Anschaffungskosten senkt, die Manipulierbarkeit der Geräte jedoch gleichzeitig in vorteilhafter Weise verbessert. Ferner soll die Optik und Oberflächengestaltung derartiger Geräte verbessert werden, ohne den Materialverbrauch oder den Herstellungsaufwand zu steigern.So it corresponds to this tendency, e.g. at a room temperature of 25 ° C, a surface temperature of the hottest zones of the radiator members of e.g. To reach 110 ° C, which corresponds to a temperature difference of 85 ° C (currently specified according to the EC standard). At the same time as the energy savings, an improved convection and thus a pleasant indoor climate is achieved. In addition, there is the advantage of reducing the number of radiator elements with the same heat output, which saves material and reduces acquisition costs, but at the same time advantageously improves the manipulability of the devices. Furthermore, the optics and surface design of such devices are to be improved without increasing the material consumption or the manufacturing outlay.

Die Erfindung hat sich ferner das Ziel gesteckt, auf einfache, produktionstechnisch ökonomische, und bestehende Herstellungsprozesse nur unwesentlich verändernde Weise derartige, mit erhöhter Temperaturdifferenz arbeitende Elektroradiatoren mit Ölfüllung zu schaffen, deren Manipulierbarkeit, Ahnsehnlichkeit und Gebrauchssicherheit im Vergleich zu Geräten bisheriger Bauweise nicht vermindert ist.The invention has also set itself the goal of creating in a simple, production-technically economical, and existing manufacturing processes only insignificantly changing, such operating with increased temperature difference electric radiators with oil filling, the manipulability, resemblance and safety in use is not reduced compared to devices of previous design.

Diese Ziele werden erfindungsgemäß bei einem Radiator der eingangs genannten Art mit dem im Kennzeichen des Patentanspruches 1 angeführten Merkmalen erreicht.These goals are achieved according to the invention in a radiator of the type mentioned at the outset with the features stated in the characterizing part of patent claim 1.

Durch die Verbannung des erhitzten Wärmeträgerfluids aus dem Außenkonturbereich der Schweißränder der Radiatorrippen und die "verbreiterte" Ausbildung der Ränder bzw. Randzonen und die damit erhöhte Oberfläche der nicht ölführenden Teile für Wärmeabgabe kann der innenliegende ölgefüllte Körper auf wesentlich erhöhte Temperatur gebracht werden, ohne daß an der Außenkontur des Gerätes, also im speziellen Fall z.B. an bzw. auf den nach außen weisenden Schweißnähten an den beiden Seiten und an der Oberseite des Radiators, eine erhöhte Temperatur auftritt oder daß ein T von 85° überschritten wird.Due to the banishment of the heated heat transfer fluid from the outer contour area of the welding edges of the radiator fins and the "widened" design of the edges or edge zones and the increased surface area of the non-oil-carrying parts for heat emission, the internal oil-filled parts can Bodies are brought to a significantly higher temperature without an elevated temperature occurring on the outer contour of the device, that is to say in the special case, for example, on or on the outward-facing weld seams on both sides and on the top of the radiator, or without a T of 85 ° is exceeded.

Besonders vorteilhaft ist die Anordnung von die Wärmeleitung hemmenden Schlitzen und/oder Wärmeleitungs-Hemmkanälen im Bereich der verbreiterten Randzonen.The arrangement of slits and / or heat conduction inhibiting channels that inhibit heat conduction is particularly advantageous in the region of the widened edge zones.

Im Sinne eines üblichen Gebrauches kann von einer Verbreiterung der geschweißten Randzone der Radiatorglieder an der Unterseite des Radiators abgesehen werden und nur die im Anspruch 2 genannten Seiten der Glieder die neuen verbreiterten und gleichzeitig vom Wärmeöl freigehaltenen Randzonen aufweisen, wobei relativ gleichmäßige und niedrige Konturtemperaturen der Radiatoren erzielt werden.In the sense of normal use, widening of the welded edge zone of the radiator members on the underside of the radiator can be dispensed with and only the sides of the members mentioned in claim 2 have the new widened and at the same time kept free from the heating oil edge zones, with relatively uniform and low contour temperatures of the radiators be achieved.

Ferner können in den bezüglich Körperkontakt extremen Eck- bzw. Kantenpositionen der Radiatoren besonders zuträgliche, niedrige Temperaturen trotz erhöhter Radiatorkörpertemperaturen mit der speziellen Ausbildung der Ränder bzw. der Randzonen-Übergänge erzielt werden.Furthermore, in the corner or edge positions of the radiators, which are extremely beneficial with regard to body contact, low temperatures can be achieved with the special design of the edges or the edge zone transitions, in spite of increased radiator body temperatures.

Bevorzugte Randzonen-Breiten-Verhältnisse, etwa für mobile 1000 bis 3500 Watt-Raumheizgeräte gibt der Anspruch 3 wieder, wobei in absoluten Werten ausgedrückt für derartige Geräte die Randbreiten etwa die bevorzugten Minimalwerte aufweisen können.Preferred boundary zone-width ratios, for example for mobile 1000 to 3500 watt space heaters, are given in claim 3 , wherein expressed in absolute values for such appliances the edge widths can have approximately the preferred minimum values.

Um eine Diffusion von Wärmeträgeröl in die von den ölgefüllten Rippenkörpern nach außen abstehenden, "verbreiterten" Rippen-Ränder und damit eine Minderung von deren Effekt mit besonderer Sicherheit zu vermeiden, ist eine Ausbildungsform der Radiatorrippen gemäß Anspruch 4 besonders vorteilhaft.In order to avoid diffusion of heat transfer oil into the “widened” rib edges projecting outward from the oil-filled rib bodies and thus to reduce their effect with particular certainty, an embodiment of the radiator ribs according to claim 4 is particularly advantageous.

Da bei üblichem Betrieb der mobilen, aufrechtstehenden Radiatoren Kontakte mit deren Unterseite im wesentlichen praktisch auszuschließen sind, kann bei gleichzeitig auch schmäleren Ausbildung der Randzone an der Unterseite ein Ineinanderlaufen von innerer und äußerer Schweißnaht gemäß Anspruch 5 vorgesehen sein, was auch die Randzonenbreite dort vermindert. Es soll an dieser Stelle nicht unerwähnt bleiben, daß die Anordnung von zwei Bindungszonen im Abstand voneinander im Sinne eines Sandwicheffektes außerdem eine wesentliche Versteifung und mechanische Stabilisierung der Außeneinwirkungen, z.B. durch Umkippen des Radiators, am meisten ausgesetzten und durch die erfindungsgemäße Verbreiterung an sich geschwächter Ränder erzielt wird.Are virtually eliminated since with the usual operation of the mobile upright radiators contacts with its bottom substantially at the same time narrower configuration of the edge zone may be at the bottom running together of the inner and outer weld seam according to claim 5 may be provided, which is also the edge zone width is reduced there. At this point it should not be left unmentioned that the arrangement of two binding zones at a distance from one another in the sense of a sandwich effect also substantially stiffens and mechanically stabilizes the external influences, for example due to the radiator tipping over, the most exposed and weaker per se due to the widening according to the invention is achieved.

Ausgestaltungen der Innenbindungszone der verbreiterten Rippenränder gemäß Anspruch 8 bringen neben einer vorteilhaften Stabilisierung der Rippenkörper im Bereich von deren Wärmeträger-Durchtritts-öffnungen den Vorteil besonders verbreiteter und damit "kühlerer" Randzonen im Bereich der Außenkonturkanten des Radiators, die auch schon weiter oben erwähnt wurden.Embodiments of the internal bond zone of the widened ribs edges of claim 8 bring addition to an advantageous stabilization of the ribs body in the area of its heat-transfer-passage openings advantage particularly widespread and "cooler" edge zones in the region of the outer contour edge of the radiator, which were also mentioned earlier.

Die Ausbildung bzw. Anordnung eines Wärmeleitungs-Hemmkanals im verbreiterten Randbereich bewirkt einerseits eine weitere Herabsetzung der Außenkontur-Temperaturen des Radiators im Betriebszustand, bzw. ermöglicht bei gleichen Außenkontur-Temperaturen höhere Öltemperaturen und damit verbesserte Heizleistung der übrigen Radiatorkörperzonen und trägt anderseits zur mechanischen Verfestigung der verbreiterten Ränder der Rippen bei.The formation or arrangement of a heat conduction inhibiting channel in the widened edge region, on the one hand, brings about a further reduction in the outer contour temperatures of the radiator in the operating state, or, at the same outer contour temperatures, enables higher oil temperatures and thus improved heating output of the other radiator body zones and, on the other hand, contributes to the mechanical solidification of the radiator widened edges of the ribs at.

Eine weitere, geminderte Außenkontur-Temperaturen gewährleistende Bauvariante sieht alternativ oder zusätzlich, wie aus Anspruch 6 näher hervorgeht, die Anordnung eines zumindest im PersonenkontaktBereich verlaufenden bzw. angeordneten Wärmeleit-Hemmkanals vor, der im übrigen ebenfalls versteifende Funktion hat.Another construction variant which ensures reduced outside contour temperatures provides, alternatively or additionally, as is apparent from claim 6 , the arrangement of a heat conduction channel which runs or is arranged at least in the area of personal contact and which also has a stiffening function.

Jeweils der Unterseite der Radiatorglieder zugeordnete Fortsätze des Wärmeübergangs-Hemmkanals der einzelnen Rippen gemäß Anspruch 7 schützen die unteren Kantenzonen des Radiators dort, wo eventuell Fußkontakte mit Personen erfolgen können. Daneben bewirken sie auch eine weitere mechanische Versteifung. Fertigungstechnisch vereinfachend ist eine Anordnung des Wärmeleit- Hemmkanals in Nachbarschaft zur Außenbindungszone der Ränder bzw. Randzonen der Radiatorrippen.Each of the underside of the radiator members assigned extensions of the heat transfer inhibiting channel of the individual ribs according to claim 7 protect the lower edge zones of the radiator where foot contact with people can possibly occur. In addition, they also cause further mechanical stiffening. An arrangement of the thermal conduction channel in the vicinity of the outer bonding zone of the edges or edge zones of the radiator ribs is simpler in terms of production technology.

Ebenfalls im Sinne möglichst hoher Temperaturdifferenzen zwischen Heizkörper und Raumtemperatur bei gleichzeitig auf niedriger Temperatur gehaltenen Außenkonturen des Radiators ist eine Wärmeleit-Hemmöffnung in den verbreiterten Rändern bzw. Randzonen der Radiatorglieder vorsehende Bauweise gemäß Anspruch 8. Dabei ist eine Anordnung der genannten Öffnungen in unmittelbar begleitender Nachbarschaft zur Innenbindungszone der verbreiterten Ränder wärme-, festigkeits- und fertigungstechnisch bzw. die Lage der Schlitze sicherheitstechnisch von besonderem Vorteil.Likewise in the sense of the highest possible temperature differences between the radiator and room temperature with the outer contours of the radiator being kept at a low temperature at the same time, a heat-conducting inhibition opening in the widened edges or edge zones of the radiator members provides a construction according to claim 8 . An arrangement of the openings mentioned in the immediately adjacent neighborhood to the inner binding zone of the widened edges is particularly advantageous in terms of heat, strength and production technology, or the location of the slots in terms of safety technology.

Eine gewisse Randzonenversteifung kann auch ein Verzicht auf die Wärmeleitungs-Hemmschlitze etwa im Bereich der Oberseite der Rippenränder gemäß Anspruch 9 bringen.A certain stiffening edge zone can also abandoning the heat conduction Hemmschlitze approximately in the region of the upper side of the rib edges according bring claim. 9

Schließlich ist es von Vorteil, an beiden Frontseiten des Radiators, also an den Außenseiten des ersten und letzten, begrenzenden Radiatorgliedes jeweils Schutzhauben od.dgl. gemäß Anspruch 10 anzuordnen.Finally, it is advantageous on both front sides of the radiator, that is to say on the outer sides of the first and last, delimiting radiator element protective hoods or the like. to arrange according to claim 10 .

Dazu ist ergänzend auszuführen, daß bei den bisher bekannten Ausführungsarten von Radiatoren auf einer Seite eine derartige Haube vorgesehen ist, in welcher u.a. die Temperaturregel- und Schalteinrichtung, der Anschluß für die Heizpatrone, das Stromzuführungskabel mit Stecker u.dgl. untergebracht sind. Diese Funktionen können selbstverständlich einer oder beiden der Schutzhauben gemäß Anspruch 10 zugeordnet sein.In addition, it must be stated that in the previously known types of radiators, such a hood is provided on one side, in which, among other things, the temperature control and switching device, the connection for the heating cartridge, the power supply cable with plug and the like. are accommodated. These functions can of course be assigned to one or both of the protective hoods according to claim 10 .

Anhand der Zeichnung wird die Erfindung näher erläutert, wobei Fig. 1 eine allgemeine, teilexpandierte Schrägansicht eines erfindungsgemäßen Gerätes zur Erläuterung von dessen Hauptkomponenten und -merkmalen, Fig. 2 eine Ansicht einer besonders bevorzugten Ausführungsform eines Gliedes des neuen Radiators und Fig. 3 eine Schnittansicht des Radiatorgliedes entlang einer Ebene A-A' gemäß Fig. 2 darstellen, und Fig. 4 eine Detaillösung zeigt.The invention is explained in more detail with reference to the drawing, in which FIG. 1 shows a general, partially expanded oblique view of a device according to the invention to explain its main components and features, FIG. 2 shows a view of a particularly preferred embodiment of a link of the new radiator, and FIG. 3 shows a sectional view of the radiator element along a plane AA 'according to FIG. 2, and FIG. 4 shows a detailed solution.

Der in Fig. 1 schematisch dargestellte Radiator 100 ist aus mehreren, fluiddicht aneinanderliegend angeordneten Gliedern 10 mit Endgliedern 10', 10'' gebildet, deren miteinander in Verbindung stehende Innenräume mit einer Wärmeträgerflüssigkeit gefüllt sind, welcher mittels praktisch alle Glieder durchsetzenden Elektroheizstab 6 od.dgl. beheizbar sind. Mittels mit Bügeln 501 an der Unterseite des Radiators 100 befestigtem Rollengestell 5 ist derselbe leicht an seiner Einsatzstelle, z.B. innerhalb einer Wohnung, bewegbar. Die einzelnen Rippenkörper weisen - auf dieser Zeichnung vollumfänglich umlaufend dieselben umgebend, eine nach außen gerichtete, im Vergleich zu Radiatoren bisheriger Bauart, insbesondere wesentlich verbreiterte Randungen 2 mit seitlichen Längsrandzonen 201 und 202 und oberen und unteren Randzonen 203 und 204 auf, die infolge ihrer Breite im wesentlichen niedere, ungefährliche Temperatur auch bei hocherhitztem Wärmeöl im Radiator-Innenraum aufweisen. Diese Randung 2 weist zumindest an ihrer Außenseite eine schließende Schweißnaht, z.B. eine Elektro-Rollschweißnaht 21, auf. Die beiden Endglieder 10' und 10'' sind jeweils an ihren Frontflächen 205,206 mit den - auch an den restlichen Rippen 10 angeordneten - Profilierungsprägungen 24,31,32 mit abnehmbaren Schutzhauben 45,45' mit Konvektionsschlitzen 451,452 praktisch vollflächig abgedeckt.The radiator 100 shown schematically in Fig. 1 is formed from a plurality of fluid-tightly arranged links 10 with end members 10 ', 10' ', the interconnecting interiors of which are filled with a heat transfer fluid which, by means of practically all the links, passes through the electric heating element 6 or. the like are heated. By means of a roller frame 5 fastened with brackets 501 to the underside of the radiator 100, the same is easily at its place of use, e.g. within an apartment, movable. The individual rib bodies have - in this drawing, all the way around them, an outward-facing, in comparison to radiators of the previous type, in particular significantly widened edges 2 with lateral longitudinal edge zones 201 and 202 and upper and lower edge zones 203 and 204, which due to their width have essentially low, harmless temperature even with highly heated heating oil in the interior of the radiator. This border 2 has at least on its outside a closing weld, e.g. an electric roll weld seam 21 on. The two end members 10 'and 10' 'are each practically completely covered on their front surfaces 205, 206 with the profiled embossments 24, 31, 32, which are also arranged on the remaining ribs 10, with removable protective hoods 45, 45' with convection slots 451, 452.

Die Abdeckhaube 45 enthält Ausnehmungen 453 bzw. Aufsätze 454 od.dgl. für die Unterbringung von Steuer- und Schaltorganen, Kabeln u.dgl.The cover 45 contains recesses 453 or attachments 454 or the like. for the accommodation of control and switching elements, cables and the like.

Die in Fig.2 in Aufsicht gezeigte und in Fig.3 entlang A-A' geschnittene Radiatorrippe 10 ist aus zwei symmetrisch zur einen Mittelebene profilpreßgeprägten Halbschalen 110,110' mit gegenseitiger Bindung über flache Außenränder gebildet.The radiator rib 10 shown in top view in FIG. 2 and cut along AA ′ in FIG. 3 is composed of two symmetrical to the central plane Press-molded half-shells 110, 110 'with mutual binding formed over flat outer edges.

Die Rippe 10 hat etwa länglich rechteckige Außenkontur mit abgerundeten Eckbereichen und weist einen umlaufenden Rand 2 mit seitlichen Randzonen 201 und 202 mit einer jeweiligen Breite b sowie einer oberen und einer unteren Randzone 203,204 mit - hier geringeren Breiten - auf. Die Gesamtbreite der Radiatorrippe 10 selbst ist mit B bezeichnet. Im oberen und unteren Bereich weist das Radiatorglied 10 kreisrunde Wärmefluid-Durchgangsöffnungen 35,35' mit zum fluiddichten Anschluß an die Nachbarglieder vorgesehenen konzentrischen Dichtpreßflächen 351,351' auf. Nach außen hin sind die Randzonen 201 bis 204 bzw. ist der Rand 2 durch einen Bindungsbereich, insbesondere eine äußere Schweißnaht 21, begrenzt.The rib 10 has an approximately oblong outer contour with rounded corner areas and has a circumferential edge 2 with lateral edge zones 201 and 202 with a respective width b and an upper and a lower edge zone 203, 204 with - here smaller widths. The total width of the radiator fin 10 itself is designated by B. In the upper and lower region, the radiator member 10 has circular heat fluid through openings 35, 35 'with concentric sealing press surfaces 351, 351' provided for the fluid-tight connection to the neighboring members. To the outside, the edge zones 201 to 204 or the edge 2 are delimited by a binding area, in particular an outer weld seam 21.

Zum das Wärmeübertragungsöl enthaltenden hohlen Rippenkörper 3 hin ist der Rand 2 durch eine zweite, eine Diffusion des Wärmeöls in den Rand 2 verhindernde innere Schweißnaht 23 mit im oberen Bereich und im unteren Bereich die Öffnungen 35',35 etwa konzentrisch umgebenden Rundungsbereichen 231',231 abgeschlossen, wodurch in den Eckbereichen jeweils zuerst sich "verbreiternde" dann wieder "verengende" Randzoneneckbereiche 235 ausgebildet sind.The edge 2 is towards the hollow rib body 3 containing the heat transfer oil by means of a second inner weld seam 23 preventing diffusion of the heat oil into the edge 2, with rounded areas 231 ', 231 surrounding the openings 35', 35 approximately concentrically in the upper area and in the lower area Completed, whereby first "widening" then "narrowing" peripheral zone corner areas 235 are formed in the corner areas.

An die äußere Schweißnaht nach innen hin anliegend ist mit beidseitig seitlich und oben verlaufenden und im unteren Bereich nach innen gerichtete Fortsätze 221,221' aufweisenden Kanalabschnitten insgesamt ein luftgefüllter Wärmeleit-Hemmkanal 22 angeordnet, der dem Rippenrand 2 eine von außen als Verdickung wahrnehmbare Zone verleiht. Weiter nach innen hin ist eine durch aneinander liegende Sickungen der Halbschalen 110,110' gebildete, vom erhitzten Öl nicht erreichbare bzw. infundierbare "flache" Zone 24 angeordnet, welche Wärmeleit-Hemmschlitze 25 aufweist, die an der Oberseite und Unterseite des Radiatorgliedes hier nicht vorgesehen sind.Adjoining the outer weld seam towards the inside, with channel sections running on both sides laterally and at the top and with inward extensions 221, 221 'in the lower area, an air-filled heat-conducting inhibiting channel 22 is arranged, which gives the rib edge 2 a zone which is perceivable from the outside as a thickening. Further inward is a "flat" zone 24, formed by adjacent beads of the half-shells 110, 110 ', which cannot be reached or infused by the heated oil and which has heat-conducting inhibiting slots 25, which are not provided here on the top and bottom of the radiator element .

Die Schlitze 25 sind unmittelbar an die fluiddichte, innere Schweißnaht 23 nach außen hin anliegend, dieselbe begleitend angeordnet. Durch zwei Längs-Sickungen 32 und 32' wird der eigentliche Ölheizkörper 3 in drei den Ölumlauf geregelt begünstigende Längshohlräume 31,31',31'' geteilt, welche gegebenenfalls, wie durch unterbrochene Linien angedeutet, bis auf einander zulaufend in die Öffnungen (35,35') für den Öldurchtritt hineingezogen sein können.The slots 25 are directly adjacent to the fluid-tight, inner weld seam 23 and are arranged to accompany the same. By means of two longitudinal beads 32 and 32 ', the actual oil heater 3 is divided into three longitudinal cavities 31, 31', 31 '' which favor the oil circulation and which, as indicated by broken lines, taper into the openings (35, 35 ') can be drawn in for the oil passage.

Das Detail der Fig.4 zeigt bei sonst analogen Bezugszeichen eine auch an der Oberseite des Radiatorgliedes 10 innerhalb von dessen verbreiterter Randzone 203 angeordnete Reihe von Wärmeleit-Hemmöffnungen 25.The detail in FIG. 4 shows, with otherwise analogous reference numerals, a row of heat-conducting inhibition openings 25 which is also arranged on the upper side of the radiator element 10 within its widened edge zone 203.

Weitere bauliche vorteilhafte Ausführungsformen, die zu dem Ziel beitragen, die Außentemperatur der Heizrippen bzw. -glieder zu senken, sind in den Ansprüchen 11 bis 18 beschrieben.Further structurally advantageous embodiments that contribute to the goal of lowering the outside temperature of the heating fins or members are described in claims 11 to 18.

Bei einer Vorgangsweise gemäß Anspruch 11 sind die Halbschalen an ihren äußeren Rändern stabil verbunden und bieten einen optisch einwandfreien Eindruck, insbesondere keine klaffenden Spalten.In a procedure according to claim 11, the half-shells are stably connected at their outer edges and offer an optically perfect impression, in particular no gaping gaps.

Gemäß Anspruch 12 wird erreicht, daß der Heizkörper ein exaktes geometrisches Aussehen besitzt bzw. daß auf beiden Seiten der Halbschalen des Gliedes gleiche Temperaturverläufe bzw. ein gleicher Wärmetransport vorhanden ist.According to claim 12 it is achieved that the radiator has an exact geometric appearance or that on both sides of the half-shells of the link the same temperature profiles or the same heat transfer is available.

Wenn gemäß Anspruch 14 vorgegangen wird, wird erreicht, daß zuerst der Wärmetransport gehemmt wird und erst dann eine Abgabe der Wärme aufgrund vergrößerter Konvektion im Bereich des Wärmeleitungs-Hemmkanales erfolgt.If one proceeds according to claim 14, it is achieved that the heat transport is inhibited first and only then is the heat given off due to increased convection in the area of the heat conduction inhibiting channel.

Wenn gemäß Anspruch 15 vorgegangen wird, so wird durch diese Maßnahme erreicht, daß im oberen Bereich des Heizkörpers in den Halbschalen der Wärmekanal 23 rundum und ununterbrochen erfolgen kann bzw. daß auch in diesem Bereich ausreichend Platz für Schlitze 25 vorgesehen ist. Gemäß Anspruch 17 ist der Wärmeleitungs-Hemmkanal 23 geschlossen, um Verunreinigungen desselben bzw. Staubablagerungen in diesem Kanal 23 zu vermeiden bzw. eine einfach herzustellende Ausführungsform dieses Kanals zu erreichen. Die von dem zumindest einem Wärmeleitungs-Hemmkanal 23 erreichte Wärmeabgabe aufgrund der vergrößerten Oberfläche der Halbschalen bzw. des Gliedes 10 reichen aus, um die Außentemperatur in den äußeren Randbereichen des Gliedes 10 auf einen annehmbaren Wert herabzusetzen.If one proceeds according to claim 15, this measure ensures that in the upper region of the radiator in the half-shells the heat channel 23 can take place all around and uninterrupted or that sufficient space for slots 25 is also provided in this region. According to claim 17, the heat conduction inhibiting channel 23 is closed in order to avoid contamination of the same or dust deposits in this channel 23 or to achieve an embodiment of this channel that is easy to manufacture. The heat emission achieved by the at least one heat conduction inhibiting channel 23 due to the enlarged surface of the half-shells or the link 10 is sufficient to reduce the outside temperature in the outer edge regions of the link 10 to an acceptable value.

Eine einfache Herstellung des Radiators wird erreicht, wenn gemäß dem Anspruch 18 vorgegangen wird; die Ausbildung des Wärmeleitungshemmkanales 23 durch einander symmetrisch gegenüberliegende Ausbauchungen bzw. Verformungen im Zuge der Herstellung der Halbschalen ermöglicht, daß idente Halbschalen zu einem Glied 10 mit Schlitzen 25 und/oder Kanälen 23 zusammengesetzt werden.A simple manufacture of the radiator is achieved if the procedure is as claimed in claim 18; the formation of the heat conduction channel 23 by means of symmetrically opposite bulges or deformations in the course of the manufacture of the half-shells enables identical half-shells to be assembled into a link 10 with slots 25 and / or channels 23.

Einfach ist, wenn die Wärmeleitungs-Hemmkanäle 23 direkt an die Außenbindungszone angrenzen, da damit trotz Ausbildung der Wärmeleitungs-- Hemmkanäle ein ordnungsgemäßer allseitiger Verschluß der Glieder nach außen zu gewährleistet wird. Soferne keine Schlitze in dem Glied ausgebildet werden, könnte diese Ausbildungszone als zusätzlicher Sicherheitsverschluß für einen Austritt des Heizfluides aus der inneren Innenbindungszone gedacht sein.It is simple if the heat conduction inhibiting channels 23 directly adjoin the external bonding zone, since despite the formation of the heat conduction inhibiting channels a proper all-round closure of the links to the outside is thereby ensured. If no slits are formed in the link, this formation zone could be thought of as an additional safety seal for the heating fluid to escape from the inner bond zone.
