Abstract

The radiator contains a large number of transverse through holes (15). Two or more sidewalls (22,24) spaced apart and preferably parallel are sealed together by a peripheral one (25). The holes are formed by distance-sleeves (20) joining the sidewalls together at the perforations. The peripheral wall can be formed by bending over one of the sidewalls at the periphery. The sleeves can be welded by laser to the sidewall inside surfaces, the weld seam forming a watertight joint.

Description

Die Erfindung betrifft einen Heizkörper, vorzugsweise zum Anschluss an eine Zentralheizung, welcher zumindest teilweise gitterförmig ausgebildet ist und daher eine Anzahl von queren Durchgangslöchern aufweist, wobei mindestens zwei im Abstand, vorzugsweise parallel zueinander angeordnete Seitenwände vorgesehen sind.The invention relates to a radiator, preferably for connection to a central heating, which is at least partially grid-shaped and therefore has a number of transverse through holes, wherein at least two spaced apart, preferably parallel to each other Side walls are provided.

Bei einem gattungsmässigen Radiator nach der Druckschrift US-A-1,363,165 ist eine ebene Platte und eine parallel zu dieser angeordnete Frontplatte vorgesehen. Die Frontplatte ist hierbei mit einer Anzahl von becherförmig gebogenen Erhöhungen versehen. Diese Frontplatte liegt hierbei mit diesen vorstehenden Biegungen an der eben ausgebildeten Platte an, wobei sie an diesen Stellen mittels nietenartigen hohlen Befestigungslementen aneinander zusammengedrückt sind. An der Aussenseite sind diese Platten nach aussen gebogen und von einem Gehäusekanal in aufwendiger Weise ummantelt. Damit benötigt dieser Radiator viel Platz. Nachteilig ist ausserdem, dass die eine mit gebogenen Erhöhungen versehene Platte aufwendig herzustellen ist und dass dieselben nur in einem begrenzten Masse die Dichtheit mit diesen Befestigungselmenten nicht dauerhaft gewährleistet ist.In a generic radiator according to US-A-1,363,165 is a flat plate and one arranged parallel to it Front plate provided. The front panel comes with a number of cup-shaped bends. This front panel lies here with these protruding bends on the one just formed Plate, at these points using rivet-like hollow fastening elements are pressed together. On the outside these plates are bent outwards and from a housing channel in encased in a complex manner. This means that this radiator takes up a lot of space. Another disadvantage is that the one provided with curved ridges Plate is expensive to manufacture and that the same only in a limited Do not permanently measure the tightness with these fastening elements is guaranteed.

Ein weiterer erheblicher Nachteil bei dem Radiator besteht darin, dass die hohlen Befestigungselemente nicht unmittelbar mit dem durchfliessenden Wasser beaufschlagt sind und dass daher nur eine beschränkte ungenügende Wärmeübertragung an die den Radiator umgebende Luft erfolgt. Mit diesen Befestigungselementen entsteht eine Art tote Zone, bei der nur eine sehr minimale Konvektion erfolgt.Another significant disadvantage with the radiator is that the hollow fasteners not directly with the flowing Water is applied and therefore only a limited insufficient Heat is transferred to the air surrounding the radiator. With These fasteners create a kind of dead zone in which only one very minimal convection takes place.

Ein bekannter Heizkörper gemäss der Druckschrift DE-U-9114197.4 besteht aus zwei Platten, von denen die eine aussen im Querschnitt U-förmig umgebogen ist und die andere auf diese eine Wanne bildende Platte aufgeschweisst ist. Im Innern der Platten sind ferner Versteifungsriegel angebracht. Dieser in seiner Form einfache Heizkörper verfügt nicht über eine spezielle optische Ausgestaltung.A known radiator according to DE-U-9114197.4 exists of two plates, one of which is U-shaped in cross-section on the outside is bent and the other welded onto this plate forming a tub is. Stiffening bars are also fitted inside the panels. This simple radiator does not have one special optical design.

Bei einem Verfahren zur Herstellung eines Plattenradiators gemäss DE-A-2 030 227 wird bei dem fertiggeschweissten Radiator ein Durchgangsloch geschaffen, durch welches ein Distanzring geführt wird, der aufweitbar ist und diese Aufweitung mittels einer Aufweitvorrichtung erfolgt. Dieser Distanzring hat in seiner Wandung Öffnungen, ist daher nicht dicht und dient nur für den Anschluss des Radiators.In a method for producing a plate radiator according to DE-A-2 030 227 becomes a through hole in the welded radiator created, through which a spacer ring is guided, which is expandable and this expansion takes place by means of an expansion device. This spacer ring has openings in its wall, is therefore not tight and serves only for connecting the radiator.

Bei einem bekannten Heizkörper gemäss dem Internationalen Modellschutz Nr. DM/035 198 ist die Gitterform durch ein Zusammensetzen von Rohrteilen oder Profilen sowie entsprechenden Zwischenstücken erzeugt. So sind beispielsweise für einen Heizkörper mit rechteckiger Aussenform zwei äussere Längsrohre, eine Anzahl zwischen diesen nacheinander angeordnete Querrohre und zwischen den letzteren Querrohren jeweils mehrere Zwischenstücke vorgesehen. Diese Längs- und Querrohre sowie die Zwischenstücke sind durch Schweissung oder Löten miteinander verbunden und bilden insgesamt eine Gitterform. Nachteilig bei diesem bekannten Heizkörper ist die relativ aufwendige Herstellung, welche durch diese Zusammensetzung und Verschweissung der verschieden langen Rohre erforderlich ist.With a known radiator according to the international model protection No. DM / 035 198 is the lattice shape by assembling Pipe parts or profiles and corresponding intermediate pieces created. For example, for a radiator with a rectangular outer shape two outer longitudinal tubes, a number arranged one after the other between them Cross tubes and several each between the latter cross tubes Intermediate pieces provided. These longitudinal and transverse tubes as well as the Intermediate pieces are connected to one another by welding or soldering and form an overall grid shape. A disadvantage of this known Radiator is the relatively complex manufacture that this creates Composition and welding of pipes of different lengths required is.

Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, einen Heizkörper nach der eingangs erwähnten Gattung derart weiterzubilden, dass mit ihm eine einfache und kostengünstige Herstellung sowie bei einer optimalen Wärmeübertragungsfähigkeit eine vielfältigere Ausgestaltung der Lochformen, der Lochabstände sowie der Heizkörper-Aussenform ermöglicht ist.In contrast, the object of the present invention is to provide a To further develop radiators according to the type mentioned at the beginning, that with it a simple and inexpensive manufacture as well as at a optimal heat transfer capability a more diverse design the hole shapes, the hole spacing and the radiator outer shape is.

Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass die Seitenwände am Aussenmantel von wenigstens einer Stirnwand dicht zusammengefügt sind, wobei zur Bildung der queren Durchgangslöcher und/oder der Löcher jeweils eine die Seitenwände im Abstand zueinander verbindende Distanzhülse und in der einen oder in beiden Seitenwänden eine Lochung vorgesehen ist, wobei die jeweilige Distanzhülse beidseitig mittels Schweissen und/oder Löten je an einer Seitenwand abdichtend befestigt ist.The object is achieved in that the side walls tightly joined together by at least one end wall on the outer jacket are, whereby to form the transverse through holes and / or the holes one each connecting the side walls at a distance from each other Spacer sleeve and a perforation in one or both side walls is provided, the respective spacer sleeve on both sides by means of Welding and / or soldering is each sealingly attached to a side wall.

Mit diesem erfindungsgemässen Heizkörper lässt sich die Herstellung desselben vereinfachen, insbesondere deswegen, weil dieser Heizkörper durch seine Ausgestaltung in einem automatisierten Betrieb gefertigt werden kann. Bei einer normalen Ausführung werden lediglich zwei gleiche perforierte Seitenwände und eine Anzahl von identisch ausgebildeten Distanzhülsen benötigt. The manufacture of the same can be done with this radiator according to the invention simplify, especially because this radiator through its design can be manufactured in an automated operation can. In a normal version, only two of the same perforated Side walls and a number of identical spacers needed.

Fig.4 zeigt in einem teilweisen Querschnitt einen Heizkörper, bei dem die Seitenwände 40 am Rand nicht abgebogen, sondern durch einen separaten, im Querschnitt zum Beispiel U-förmigen Rahmen 42 miteinander verbunden sind. Dieser U- oder andersförmige Rahmen 42 ragt mit seinen beiden Schenkeln 44 ins Innere des Heizkörpers, und er ist auf der Aussenseite dieser Schenkel 44 an die Metallbleche angelötet oder anderweitig befestigt.Fig.4 shows in a partial cross section a radiator in which the Side walls 40 not bent at the edge, but by a separate, connected in cross section, for example, U-shaped frame 42 are. This U-shaped or other-shaped frame 42 projects with its two Legs 44 inside the radiator and it is on the outside this leg 44 soldered to the metal sheets or otherwise attached.

Fig.4 verdeutlicht darüberhinaus eine weitere vorteilhafte Herstellungsart der Verbindung der Distanzhülsen 45 mit den Seitenwänden 40. Diese Distanzhülsen 45 sind jeweils - wie durch deren linksseitige Ausgangsform dargestellt ist - vorerst in Lochungen 15' der als Metallbleche verwendeten Seitenwände 40 positioniert. Diese Hülsen 45 weisen zweckmässigerweise je einen Absatz 46 auf, welcher als Anschlag der Seitenwände 40 dient. Diese Distanzhülsen 45 sind von Hartlötringen 49 umgeben, welche jeweils innen- und aussenseitig an den Seitenwänden 40 anliegen. Das zu den Aussenflächen der Seitenwände 40 gebildete jeweilige vorstehende Ende 47 der Hülse 45 wird nach der gegenseitigen Positionierung von beidseitig je einem koaxial gegen die Hülse gepressten Verformwerkzeug 48 vernietet. Rechter Hand sind die gleichzeitig gegen die Hülse 45 gedrückten Verformwerkzeuge 48 in Bearbeitungsposition, derweil sie links in der Ausgangsstellung veranschaulicht sind. Nach dem Vernieten der Distanzhülsen 45 kann der gesamte vorgefertigte Heizkörper für das Hartlöten in einen Durchlaufofen eingeführt und darin die Verbindungsstellen der Distanzhülsen 45 mit den Seitenwänden 40 durch ein Aufschmelzen der Hartlötringe 49 zwecks Erzielung einer wasserundurchlässigen Abdichtung aneinander befestigt werden. Im Prinzip lassen sich im gleichen Arbeitsgang die Verbindungsstellen der die Aussenwand bildenden Rahmen 42 mit den Seitenwänden 40 löten.Fig. 4 also illustrates another advantageous method of manufacture the connection of the spacer sleeves 45 to the side walls 40. These spacer sleeves 45 are each - as by their left-sided original form is shown - initially in perforations 15 'of the used as metal sheets Sidewalls 40 positioned. These sleeves 45 expediently have one shoulder 46 each, which acts as a stop for the side walls 40 serves. These spacer sleeves 45 are surrounded by brazing rings 49, which rest on the inside and outside of the side walls 40. That too respective protrusions formed on the outer surfaces of the side walls 40 End 47 of the sleeve 45 is after the mutual positioning of a shaping tool pressed coaxially against the sleeve on both sides 48 riveted. On the right hand side are those pressed against the sleeve 45 at the same time Deforming tools 48 in the processing position, meanwhile left are illustrated in the starting position. After riveting the Spacers 45 can be the entire prefabricated radiator for brazing inserted in a continuous furnace and the connection points therein the spacer sleeves 45 with the side walls 40 by melting the brazing rings 49 for the purpose of achieving a watertight seal be attached to each other. In principle, the same Work the connection points of the frames forming the outer wall Solder 42 with the side walls 40.

Fig.5 zeigt eine weitere Verbindungsart der beiden Seitenwände 52, 54, die je eine Stirnwand 52', 54' aufweisen, welche rechtwinklig abgebogen und endseitig mit nach aussen gerichteten flanschartigen Rändern versehen sind. Ausserdem ist ein Distanzstück 20 dargestellt, welches stirnseitig an der Innenseite der Seitenwände mittels Schweissen und/oder Löten abdichtend befestigt ist und dessen Loch 15 bündig zu den Lochungen 15' der Seitenwände 52, 54 angeordnet ist. Als zusätzliche Variante ist eine vorteilhaft zylindrische Distanzhülse 50 dargestellt, welche beidseitig durch eine Bördelung 50 und durch Schweissen und/oder Löten an der jeweiligen Aussenwand 52, 54 befestigt ist. Zumindest die eine Seitenwand 52 ist dabei durch eine ringförmige Ausnehmung 52" nach innen zurückversetzt, so dass die Bördelung 50' zu der Frontfläche dieser Seitenwand 52 nicht vorsteht.5 shows a further type of connection of the two side walls 52, 54, which each have an end wall 52 ', 54' which is bent at right angles and provided at the end with outward flange-like edges are. In addition, a spacer 20 is shown, which on the front the inside of the side walls is sealed by welding and / or soldering and its hole 15 is arranged flush with the perforations 15 'of the side walls 52, 54. As an additional variant shows an advantageously cylindrical spacer sleeve 50, which on both sides by a flange 50 and by welding and / or soldering on the respective outer wall 52, 54 is attached. At least one side wall 52 is included set back through an annular recess 52 ", so that the flare 50 'does not protrude to the front surface of this side wall 52.

Gemäss Fig.6 können die Lochungen der Seitenwände und der Durchgangslöcher der Distanzhülsen mit einer beliebigen Querschnittsform ausgebildet sein ohne dass hierdurch eine erheblich aufwendigere Fertigung des Heizkörpers entstehen würde. So können beispielsweise abwechslungsweise runde, dreieckige und/oder viereckige Löcher 65, 75, 15 vorgesehen sein. Selbstverständlich können diese Querschnittsformen noch anders als dargestellt aussehen, so zum Beispiel schlitz- oder trapezförmig oder auch als Figuren oder Buchstaben.According to Fig.6 can the perforations of the side walls and the through holes of the spacers with any cross-sectional shape be trained without that this results in a considerably more complex manufacture of the radiator would. For example, alternating round, triangular and / or square holes 65, 75, 15 may be provided. Of course can these cross-sectional shapes still look different than shown, so for example slit or trapezoidal or also as figures or Letters.

Ausserdem kann der Heizkörper an gewissen Stellen mit Distanzhülsen 20 zwischen den Seitenwänden befestigt sein, ohne dass die vordere Seitenwand eine Lochung besitzt, sondern dass bloss an der Rückwand eine Lochung vorgesehen ist, wie dies in Fig.6 mit den strichliniert gezeigten Löchern 65', 66' veranschaulicht ist. Hierdurch kann das Aussehen des Heizköpers vorteilhaft verändert und trotzdem noch eine ausreichende Drucksicherheit desselben gewährt werden.In addition, the heating element can be provided with spacer sleeves 20 at certain points be attached between the side walls without the front side wall has a perforation, but only a perforation on the rear wall is provided, as in Figure 6 with the holes shown in dashed lines 65 ', 66'. This can change the appearance of the radiator advantageously changed and still sufficient pressure security be granted.

Fig.7 zeigt zwei parallele hintereinander angeordnete Heizkörper 55, 56, die jeweils demjenigen nach Fig. 1 entsprechen und über Verbindungselemente 58 im Abstand zueinander gehalten sind. Vorzugsweise wird bei dieser Ausführung im einen das Heizmedium eingelassen, indessen beim anderen abgeführt. Dabei wird dieses Medium durch die Verbindungselemente 58 vom einen in den andern Heizkörper geleitet. Auf diese Art könnten noch mehr als zwei Heizkörper hintereinander angeordnet sein, beispielsweise auch versetzt zueinander.7 shows two parallel radiators 55, 56 arranged one behind the other, each corresponding to that of FIG. 1 and via connecting elements 58 are kept at a distance from each other. Preferably at this version let in the heating medium, but at dissipated to others. This medium is through the connecting elements 58 passed from one to the other radiator. In this manner could be more than two radiators in a row, for example, also offset from one another.

Gemäss Fig.8 hat ein gitterförmiger Heizkörper 80 zwei parallel im Abstand zueinander angeordnete perforierte Seitenwände 82, 84, mehrere diese verbindende Distanzhülsen 20 sowie die beiden Seitenwände 82, 84 am Aussenmantel 25 rundum dicht zusammengefügte Stirnwände 82', 84'. Die Löcher 15 sind jeweils durch eine Lochung 26 in der einen Seitenwand 82, eine mit einem Durchgangsloch versehenen Distanzhülse 30 und einer Lochung in der gegenüberliegenden Seitenwand gebildet. Die Distanzhülsen 30 bestehen jeweils aus einer Hülse mit beidseitig je einem Ansatz 21, 23. Diese Ansätze 21, 23 ermöglichen sowohl eine axiale als auch eine radiale Zentrierung des Distanzhülsen 30 zwischen den Seitenwänden 82, 84. Sie sind daher zweckmässigerweise mit aussen annähernd zylindrischen Ansätzen 21, 23 ausgestaltet, indessen bei dem alternativ veranschaulichten Distanzstück 30', welches entsprechend in den Lochungen 26, 28 positioniert ist, sind die Ansätze durch Schrägungen ausgeführt. Dies kann für eine Schweissverbindung von Vorteil sein. Nach der Befestigung der Distanzhülsen mittels einer der genannten Verbindungsart kann ein nachträgliches Flachschleifen zumindest der Vorderfront der einen Seitenwand 82 erforderlich sein.8 has a grid-shaped radiator 80 two perforated side walls arranged parallel and at a distance from each other 82, 84, several spacer sleeves 20 connecting these as well as the two Side walls 82, 84 on the outer jacket 25 tightly joined together End walls 82 ', 84'. The holes 15 are each through a hole 26 in one side wall 82, a spacer sleeve provided with a through hole 30 and a perforation in the opposite side wall educated. The spacer sleeves 30 each consist of a sleeve with both sides one approach 21, 23. These approaches 21, 23 enable both an axial as well as a radial centering of the spacer sleeves 30 between the side walls 82, 84. They are therefore expediently included approximately cylindrical lugs 21, 23 are designed on the outside, but in the case of the alternatively illustrated spacer 30 ', which accordingly positioned in the perforations 26, 28, the approaches are due to bevels executed. This can be an advantage for a welded joint his. After fastening the spacer sleeves using one of the above Connection type can be a subsequent surface grinding at least Front of one side wall 82 may be required.

Beim Verbinden der beiden Bleche liegen diese Stirnwände 82', 84' aufeinander und sie werden beispielsweise von einer durchgehenden Schweissnaht über den gesamten Umfang des Aussenmantels 25 miteinander befestigt, hierdurch eine dichte Verschliessung des durch diese Bleche sowie den Distanzhülsen 30 begrenzten Hohlraumes 18 erzielt wird. Dieser Hohlraum 18 bildet damit einen dicht abgeschlossenen Kanal, bei dem einzig der Ein- 11 und Auslass 12 als Öffnungen für das Heizmedium vorgesehen sind.When connecting the two sheets, these end walls 82 ', 84' lie one on top of the other and they are, for example, by a continuous Weld seam over the entire circumference of the outer jacket 25 with one another attached, thereby a tight closure of the through these sheets and the spacer sleeves 30 limited cavity 18 is achieved. This Cavity 18 thus forms a sealed channel in which only the inlet 11 and outlet 12 are provided as openings for the heating medium are.

Ferner können bei diesem Heizkörper 80 zusätzlich Verbindungsbolzen 19 vorgesehen sein, welche zwischen den beiden Metallblechen angeordnet und an diesen angeschweisst sind. Vorteilhaft sind diese Verbindungsbolzen 19 in einem Abstand zwischen den Distanzhülsen 30 plaziert. Sie dienen als Verstärkung des Heizkörpers 10 in bezug auf die Druckfestigkeit.Furthermore, connecting bolts 19 can additionally be used in this heating element 80 be provided, which is arranged between the two metal sheets and are welded to it. These connecting bolts are advantageous 19 placed at a distance between the spacer sleeves 30. You serve as reinforcement of the radiator 10 in relation to the compressive strength.

Die symmetrische Ausbildung des Heizkörpers 80 bezüglich der längsseitigen Mittelachsen ermöglicht eine identische Ausbildung der beiden Metallbleche 22, 24, hierdurch die Herstellung dieses Heizkörpers zusätzlich vereinfacht ist.The symmetrical design of the radiator 80 with respect to the long side Central axes enable the two metal sheets to be formed identically 22, 24, thereby the production of this radiator in addition is simplified.

Fig.9 zeigt einen Heizkörper 90, der an sich beispielsweise wie derjenige gemäss Fig.2 hergestellt ist. Dieser Heizkörper 90 ist zusätzlich mit einer Kerbe 91 versehen, durch welchen der Heizkörper 90 nach dessen Herstellung mit seinem endseitigen Abschnitt 95 um die Kante 93 in einem Winkel von 90° abgebogen wird. Danach wird dieser Abschnitt 95 vorteilhaft bei der Kerbe 91 verschweisst. Damit ergibt sich ein weiterer Vorteil im Rahmen der Erfindung, denn der Heizkörper kann nicht nur in einer ebenen Ausführung, wie in Fig. 1 gezeigt ist, sondern auch abgewinkelt, U- oder andersförmig ausgebildet werden, ohne dass dies mit einem grossen Herstellungsaufwand verbunden wäre. Vorliegend ist diese Kerbe 91 in einem Winkel von 90° ausgebildet. Dieser Winkel liesse sich je nach dem gewünschten Biegewinkel entsprechend anpassen. Fig. 9 shows a radiator 90, which in itself, for example how the one is made according to Fig.2. This radiator 90 is additionally provided with a notch 91 through which the radiator 90 after its manufacture with its end section 95 .mu.m the edge 93 is bent at an angle of 90 °. After that, this one Section 95 advantageously welded to the notch 91. So that results another advantage in the context of the invention, because the radiator can not only in a flat design, as shown in Fig. 1, but also be angled, U-shaped or shaped differently without that this would involve a large manufacturing effort. Present this notch 91 is formed at an angle of 90 °. That angle could be adjusted according to the desired bending angle.

Die Erfindung ist mit den oben erläuterten Ausführungsbeispielen ausreichend dargetan. Sie liesse sich jedoch noch in anderen Varianten darstellen. So könnte nebst dem Steigrohr 13 auch eines oder mehrere Umlenkrohre im Heizkörper-Inneren geführt sein. Der Heizkörper kann eine rechteckige - wie in Fig.1 dargestellt - oder eine andersförmige Aussenform aufweisen und mit einer oder mehreren Lücken oder seitlichen Ausnehmungen versehen sein, in die beispielsweise ein Badetuch oder seinesgleichen gehängt werden kann. Auch hierzu kann ohne grossen zusätzlichen Herstellungsaufwand eine beliebige Heizkörperform kreiert werden.The invention is sufficient with the exemplary embodiments explained above demonstrated. However, it could also be represented in other variants. Thus, in addition to the riser pipe 13, one or more deflection pipes could also be used be guided inside the radiator. The radiator can rectangular - as shown in Fig.1 - or a different shape of the outside have and with one or more gaps or lateral recesses be provided, for example in a bath towel or the like can be hanged. This can also be done without much additional Any radiator shape can be created.

Ferner könnten auch die beiden Seitenwände 22, 24 in nicht paralleler Anordnung oder anders als eben ausgeführt sein. So könnten Rippen oder ähnliches in diesen Seitenwänden vorhanden sein.Furthermore, the two side walls 22, 24 could also be arranged in a non-parallel arrangement or be different than just executed.
