Description

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

Seit vielen Jahren haben sich 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, bewährt. Derartige Heizkörper sind z. B. aus der EP-A1-292 441 und EP-A1-114 158 bekannt.For many years z. B. movable on rollers, Space-heating radiators suitable for plug sockets with electrical resistance heating device, especially heating elements or easily replaceable Cartridges as flexible heaters for Transitional seasons, cold periods in the warmer Season and as additional heaters, proven. such Radiators are e.g. B. from EP-A1-292 441 and EP-A1-114 158 known.

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.They have a certain disadvantage as a result of their use electrical energy relatively high cost of such Heaters and therefore there is a tendency in the Direction to increase the heating effect to save energy by making the greatest possible difference between the Surface temperature of the radiator fins in the area of their oil filling and the prevailing one Room temperature is desired.

Aus der DE-A1-24 40 184 sind Heizkörper bekannt, bei denen eine Reihe von fluidgefüllten Kanälen nebeneinander angeordnet ist. Diese Kanäle werden zwischen den beiden Platten bzw. Halbschalen eines Radiator-Gliedes ausgebildet, wobei die Platten zwischen den ausgebildeten Kanälen aneinander anliegen und eine Schweißnaht um die Heizfluid führenden Kanäle aufweisen oder am Außenumfang miteinander verschweißt sind. Im Umfangsbereich des von den beiden plattenförmigen Elementen gebildeten Gliedes ist eine Schweißnaht ausgebildet, welche ein Austreten des Heizfluids aus den Heizkörper-Gliedern verhindert.Radiators are known from DE-A1-24 40 184, where a number of fluid-filled channels side by side is arranged. These channels are between the two plates or half-shells of a radiator link formed, with the plates between the trained channels abut each other and one Have weld seam around the channels carrying the heating fluid or welded together on the outer circumference are. In the perimeter of that of the two member formed plate-shaped elements is one Welded seam, which prevents the Prevents heating fluids from the radiator sections.

Aus der FR-PS 1,394.844 ist ein Heizkörper bekannt, der aus einer Mehrzahl von Gliedern besteht, in deren Mittelbereich ein elektrischer Heizstab eingesetzt ist. Diese aus einem Teil bestehenden plattenförmigen Glieder weisen über ihre Höhe bzw. Längserstreckung eine Anzahl von Öffnungen auf, die einerseits die Konvektion verbessern sollen und anderseits den Wärmetransport vom in der Mitte angeordneten Heizstab zum Umfang der Platten auf die Bereiche bzw. Brücken beschränken, die zwischen den Öffnungen vorhanden sind. Auf diese Weise wird der Wärmetransport vom Heizkörperinneren zum Heizkörperumfang beschränkt.A radiator is known from FR-PS 1,394,844, which consists of a plurality of links, in an electric heating element is used in the middle area is. This one-piece plate-shaped Limbs have their height or length a number of openings on the one hand, the convection should improve and on the other hand heat transport from the central heating element to the Limit the size of the slabs to the areas or bridges, that exist between the openings are. In this way, the heat transfer from Radiator interior limited to the circumference of the radiator.

Aus der EP-A1-556.433 ist ein Heizkörper der eingangs genannten Art bekannt, bei dem die einzelnen Glieder von zwei miteinander verschweißten Halbschalen gebildet werden. Die Schweißnaht, mit denen die beiden plattenförmigen Halbschalen verbunden werden, begrenzt den Bereich, in dem das Heizfluid zirkuliert. Anschließend an diesen Bereich, in dem die beiden das Glied bildenden Halbschalen aneinander anliegen, ist ein Bereich vorgesehen, in dem jede der Halbschalen in ihrem Umfangsbereich zumindst zwei Abbiegungen, gegebenenfalls auch eine dritte und vierte, Abbiegung aufweist. Diese Abbiegungen begrenzen einen kanalförmigen Raum, der vorgesehen ist, um durch Konvektionserhöhung die Temperatur der Heizkörperoberfläche zu verringern. In diesen Abbiegungen können Öffnungen ausgebildet sein, um den Wärmetransport weiter einzuschränken, da für den Wärmetransport vom Heizkörperinneren zum Umfang der Glieder nur die zwischen den Öffnungen bestehender Brücken zur Verfügung stehen.From EP-A1-556.433 is a radiator at the beginning known type, in which the individual Links of two half-shells welded together be formed. The weld seam with which the two plate-shaped half-shells are connected, limits the area in which the heating fluid circulates. Following this area where the two the half-shells forming the link lie against one another, an area is provided in which each of the half shells at least two turns in its peripheral area, if necessary, a third and fourth turn having. These turns limit a channel-shaped one Space that is intended to be increased by convection the temperature of the radiator surface to reduce. There may be openings in these turns be trained to further heat transfer restrict, because for the heat transfer from Radiator interior to the circumference of the limbs only between the openings of existing bridges stand.

Die von den Abbiegungen der Heizkörperplatten gebildete Außenwand bietet nach außen zu aufgrund der gewählten Form der Abbiegungen eine im wesentlichen glatte Oberfläche. Die Ausbildung derartiger Abbiegungen erfordert einen beträchtlichen maschinellen Aufwand und spezielle Vorkehrungen, um die Schweißnaht auszuführen, welche den fluidgefüllten Raum von den Abbiegungen im Umfangsbereich des Gliedes trennt. Der kanalförmige Raum dieses Radiators ermöglicht eine Konvektion von Luft in seinem Inneren bzw. ist dafür vorgesehen, einen Kamin zu bilden, in dem die Luft bei ihrem Durchgang von unten nach oben erwärmt wird. Dieser Kanal ist weder unten noch oben verschlossen; die den kanalförmigen Raum begrenzenden Flanschteile sind in ihren äußeren Endbereichen bzw. im äußersten Randbereich des jeweiligen Radiator-Gliedes nicht miteinander verbunden.The from the turns of the radiator panels formed outer wall offers due to the outside the chosen shape of the turns essentially one smooth surface. The formation of such turns requires a considerable amount of machine Effort and special precautions to the Execute weld seam, which the fluid-filled Space from the turns in the peripheral area of the Link separates. The channel-shaped space of this radiator allows convection of air inside or is intended to form a chimney, in which the air passes from the bottom to the bottom is heated up. This channel is neither below nor closed at the top; that delimit the channel-shaped space Flange parts are in their outer end areas or in the outermost edge area of the respective Radiator link not connected.

Dieser und auch der erfindungsgemäße Radiator entsprechen der Tendenz, z. B. bei einer Raumtemperatur von 25°C, eine Oberflächentemperatur der heißesten Zonen der Radiator-Glieder 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 gute Konvektion und damit ein angenehmes Raumklima erreicht. Ziel der Erfindung ist es, bei gleicher Wärmeabgabeleistung die Zahl der Radiator-Glieder verringern zu können, was Materialeinsparungen bringt, Anschaffungskosten senkt und die Manipulierbarkeit der Geräte in vorteilhafter Weise verbessert. Ferner soll die Optik und Oberflächengestaltung derartiger Geräte verbessert werden, ohne den Materialverbrauch oder den Herstellungsaufwand zu steigern.This and also the radiator according to the invention correspond to the tendency, e.g. B. at room temperature of 25 ° C, a surface temperature of the hottest Zones of the radiator members of e.g. B. 110 ° C to achieve what a (currently specified according to EC standard) Temperature difference of 85 ° C corresponds. At the same time as the energy savings good convection and thus a pleasant indoor climate reached. The aim of the invention is to provide the same heat output reduce the number of radiator links to be able to get what material savings, acquisition costs lowers and the manipulability of Devices improved in an advantageous manner. Furthermore, the Optics and surface design of such devices improved be without the material consumption or the Increase manufacturing costs.

Insbesondere hat sich die Erfindung zum Ziel gesetzt, 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, deren Außentemperatur auf einen annehmbaren Wert herabgesetzt ist, der keine klaffenden Spalten zwischen benachbarten Gliedern zeigt und einen stabilen Aufbau besitzt.In particular, the invention has set itself the goal of on simple, technologically economical, and existing manufacturing processes only marginally changing way, with increased temperature difference working electric radiators with oil filling to create, its manipulability, resemblance and safety in use compared to devices previous design is not reduced, the outside temperature reduced to an acceptable level that has no gaping gaps between adjacent ones Structure shows and has a stable structure.

Diese Ziele werden erfindungsgemäß bei einem Radiator der eingangs genannten Art mit dem im Kennzeichen des Patentanspruches 1 angeführten Merkmalen erreicht.According to the invention, these goals are achieved with a Radiator of the type mentioned at the outset in the license plate of claim 1 cited features reached.

Durch die Verbannung des erhitzten Wärmeträgerfluids aus dem Außenkonturbereich der Schweißränder der Radiator-Rippen und die "verbreiterte" Ausbildung der Ränder bzw. Randzonen und die damit erhöhte Oberfläche der nicht ölführenden Teile für die Wärmeabgabe kann der innenliegende ölgefüllte Körper auf wesentlich erhöhte Temperatur gebracht werden, ohne daß an derAußenkontur 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 AT von 85°C überschritten wird. Es werden ein stabiler Aufbau der Glieder und eine Verringerung der Wärmemenge erreicht, die vom Wärmeträgerfluid zu den Außenrandzonen übertragen wird.By banishing the heated heat transfer fluid from the outer contour area of the welding edges the radiator ribs and the "widened" training the margins or marginal zones and the heightened Surface of the non-oil-carrying parts for heat emission the inside of the oil-filled body brought significantly higher temperature without that on the outer contour of the device, in particular Case z. B. on or on the outside Weld seams on both sides and on the top of the radiator, an elevated temperature occurs or that an AT of 85 ° C is exceeded. It will a stable structure of the limbs and a reduction of the amount of heat reached by the heat transfer fluid is transmitted to the outer peripheral zones.

Wenn die im Anspruch 7 genannten Randzonen von Wärmeöl freigehalten sind, wird eine relativ gleichmäßige und niedrige Konturtemperatur der Radiatoren erzielt werden. Femer können in den bezüglich Körperkontakt extremen Eck- bzw. Kantenpositionen der Radiatoren besonders zuträgliche, niedrige Temperaturen trotz erhöhter Heizfluidtemperaturen erreicht werden.If the edge zones mentioned in claim 7 are kept free of heating oil, a relatively uniform and low contour temperature of the radiators will be achieved. Furthermore, in the corner or edge positions of the radiators, which are extreme with respect to body contact, particularly favorable, low temperatures can be achieved despite increased heating fluid temperatures.

Bevorzugte Randzonen-Breiten-Verhältnisse, etwa für mobile 1000 bis 3500 Watt-Raumheizgeräte, gibt der Anspruch 8 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 8, wherein, expressed in absolute values, the edge widths for such appliances can have approximately the preferred minimum values.

Eine Diffusion von Wärmeträgeröl in die von den ölgefüllten Rippenkörpern nach außen abstehenden, "verbreiterten" Randzonen und damit eine Minderung von deren Effekt vermeidet mit besonderer Sicherheit die Innenbindungszone.A diffusion of thermal oil into that of the oil-filled Ribs protruding outwards, "widened" marginal zones and thus a reduction avoids their effect with particular certainty the inner bond zone.

Da bei üblichem Betrieb der mobilen, aufrechtstehenden Radiatoren Kontakte-mit deren Unterseite im wesentlichen praktisch auszuschließen sind, kann bei gleichzeitig auch schmälerer Ausbildung der Randzone an der Unterseite ein Ineinanderlaufen von innerer und äußerer Schweißnaht gemäß Anspruch 9 vorgesehen sein, was auch die Randzonenbreite dort vermindert.Since, in the usual operation of the mobile upright radiators contacts with practically exclude the underside thereof 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 9 may be provided, which is also the edge zone width is reduced there ,

Es soll an dieser Stelle nicht unerwähnt bleiben, daß mit der Anordnung von zwei Bindungszonen, d. h. einer Innenbindungszone und einer Außenbindungszone, im Abstand voneinander, im Sinne eines Sandwicheffektes, eine wesentliche Versteifung und mechanische Stabilisierung gegen Außeneinwirkungen, z. B. durch Umkippen des Radiators, im Bereich der derartigen Einwirkungen am meisten ausgesetzten und durch die Verbreiterung an sich geschwächten Ränder erzielt wird.It should not go unmentioned here that with the arrangement of two bond zones, d. H. an inner bond zone and an outer bond zone, at a distance from each other, in the sense of a sandwich effect, an essential stiffening and mechanical Stabilization against external influences, e.g. B. by tilting the radiator in the area of such Most exposed and by effects the widening at weaker edges achieved becomes.

Die Ausgestaltung der Randzonen bringt neben einer vorteilhaften Stabilisierung der Rippenkörper im Bereich von deren Wärmeträger-Durchtritts-Öffnungen den Vorteil besonders verbreiterter und damit "kühlerer" Randzonen im Bereich der Außenkonturkanten des Radiators, die auch schon weiter oben erwähnt wurden.The design of the edge zones brings alongside one advantageous stabilization of the rib body in the area from their heat transfer openings the advantage of particularly widened and thus "cooler" Marginal zones in the area of the outer contour edges of the radiator, which have already been mentioned above.

Die Ausbildung bzw. Anordnung eines Kanals 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 channel in widened edge area causes another on the one hand Reduction of the outer contour temperatures of the Radiators in the operating state, or enables the same Outer contour temperatures higher oil temperatures and thus improved heating performance of the other radiator body zones and on the other hand contributes to the mechanical Solidification of the widened edges of the ribs at.

Jeweils der Unterseite der Radiatorglieder zugeordnete Fortsätze des Kanals der einzelnen Rippen gemäß Anspruch 11 schützen die unteren Kantenzonen des Radiators dort, wo eventuell Fußkontakte mit Personen erfolgen können. Daneben bewirken sie auch eine weitere mechanische Versteifung.In each case the bottom of the radiator elements associated with the channel extensions of the individual ribs according to claim 11 there protect the lower edge zones of the radiator, which may foot contacts can be made with people. In addition, they also cause further mechanical stiffening.

Fertigungstechnisch vereinfachend ist eine Anordnung des Kanals in Nachbarschaft zur Außenbindungszone der Ränder bzw. Randzonen der Radiatorrippen.An arrangement is simplifying production of the channel in the vicinity of the external bond zone the edges of the radiator ribs.

Ebenfalls im Sinne möglichst hoher Temperaturdifferenzen zwischen Heizkörper und Raumtemperatur bei gleichzeitig auf niedriger Temperatur gehaltenen Außenkonturen des Radiators ist eine Öffnungen zur Wärmeleitungshemmung in den verbreiterten Rändern bzw. Randzonen der Radiator-Glieder vorsehende Bauweise gemäß Anspruch 12. Dabei ist eine Anordnung der genannten Öffnungen in unmittelbar begleitender Nachbarschaft zur Innenbindungszone der verbreiterten Ränder wärme-, festigkeits- und fertigungstechnisch bzw. die Lage der Öffnungen sicherheitstechnisch von besonderem Vorteil.Also in the sense of the highest possible temperature differences between the radiator and room temperature with the outer contours of the radiator kept at a low temperature at the same time, an opening for heat conduction inhibition in the widened edges or edge zones of the radiator members is provided according to claim 12. An arrangement of the openings mentioned is immediate Accompanying neighborhood to the inner bond zone of the widened edges in terms of heat, strength and production technology, or the location of the openings is particularly advantageous in terms of security.

Eine gewisse Randzonenversteifung kann auch ein Verzicht auf die Öffnungen, etwa im Bereich der Oberseite der Rippenränder, gemäß Anspruch 13 bringen.A certain stiffening edge zone can also abandoning the openings, for example in the region of the upper side of the rib edges, bring according to claim. 13

Schließlich kann es von Vorteil sein, an beiden Frontseiten des Radiators, also an den Außenseiten des ersten und letzten begrenzenden Radiator-Gliedes jeweils Schutzhauben gemäß Anspruch 14 anzuordnen.Finally, it may be beneficial at both front sides of the radiator, that is on the outer sides of the first and last limiting radiator member respectively to arrange protective hoods according to claim fourteenth

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 und dgl. untergebracht sind. Diese Funktionen können selbstverständlich einer oder beiden der Schutzhauben gemäß Anspruch 14 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 14 .
