Description

Die Erfindung bezieht sich auf einen Radiator nach dem Oberbegriff des Anspruchs 1. Ein solcher Radiator ist aus der EP-A2-0 243 077 bekannt.The invention relates to a radiator according to the preamble of claim 1. Such a radiator is known from EP-A2-0 243 077.

Bei diesem Radiator hängt der gute Wärmeübergang zwischen den wärmeabgehenden Elementen und den Lamellen in hohem Maße von der Passung der Teile, d.h. von deren Maßhaltigkeit ab. Wegen der notwendigen Passung sind die innerhalb des Halterahmens angeordneten Elemente nur sehr schwierig in diesen einzusetzen.With this radiator, the good heat transfer between the heat-emitting elements and the fins largely depends on the fit of the parts, ie their dimensional accuracy. Because of the necessary fit, the elements arranged within the holding frame are very difficult to insert into them.

Der Erfindung liegt die Aufgabe zugrunde, einen Radiator der eingangs genannten Art anzugeben, der insbesondere für den Einsatz zur Kraftfahrzeugscheibenbeheizung geeignet ist, einen kompakten Aufbau zuläßt und einen guten Wärmeübergang zwischen den wärmeabgebenden Elementen und den Lamellen gewährleistet.The invention has for its object to provide a radiator of the type mentioned, which is particularly suitable for use for automotive window heating, allows a compact structure and ensures good heat transfer between the heat-emitting elements and the fins.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Die Erfindung gestaltet einen Radiator bekannter Art, wie er insbesondere in Kraftfahrzeugen zur Abgabe von Kühlwasserwärme benutzt wird, zu einem elektrisch betriebenen Radiator um, in dem die wärmeabgebenden Elemente von elektrischen Kaltleiterelementen beheizt sind, die von der Art sind, die üblicherweise als PTC-Widerstände bezeichnet werden.The invention transforms a radiator of a known type, such as is used in particular in motor vehicles for delivering cooling water heat, to an electrically operated radiator, in which the heat-emitting elements are heated by electrical thermistor elements, of the type which are usually known as PTC resistors be designated.

Solche PTC-Widerstände haben die Eigenschaft, daß sie in kaltem Zustand einen niedrigen elektrischen Widerstand aufweisen, der mit zunehmender Temperatur zunimmt, so daß mit steigender Temperatur der durch den PTC-Widerstand fließende Strom abnimmt. Der PTC-Widerstand hat somit selbstregelnde Eigenschaften, die eine Überhitzung des PTC-Widerstandes verhindern. Die Temperatur, die ein solcher PTC-Widerstand bei gegebener Betriebsspannung erreichen kann, läßt sich durch bestimmte Parameter bei der Herstellung beeinflussen, was hier jedoch nicht näher erläutert zu werden braucht.Such PTC resistors have the property that they have a low electrical resistance in the cold state, which increases with increasing temperature, so that the current flowing through the PTC resistor decreases with increasing temperature. The PTC resistor thus has self-regulating properties that prevent the PTC resistor from overheating. The temperature that such a PTC resistor can reach at a given operating voltage can be influenced by certain parameters during production, which need not be explained here, however.

PTC-Widerstände finden in der Technik in großem Umfang als Schutzelemente in Geräten Verwendung, in denen eine Überrhitzung durch zu hohen Betriebsstrom verhindert werden soll. Die vorgenannten, den PTC-Widerständen innewohnenden Eigenschaften müssen dann besonders beachtet werden, wenn PTC-Widerstände als Heizelemente, wie im vorliegenden Falle, eingesetzt werden. Die vorgenannte Selbstregelungseigenschaft eines PTC-Widerstandes führt dazu, daß der PTC-Widerstand keine ausreichende Wärmemenge abgeben kann, wenn die von ihm entwickelte Wärme nicht von ihm abgeführt wird. Es ist daher für einen guten Wärmeübergang zwischen dem PTC-Widerstand und dem ihn umgebenden Medium, hier ein Luftstrom, zu sorgen. Die die Erfindung weiter kennzeichnenden Merkmale sind auf die Lösung dieser Problematik gerichtet. Es ist insbesondere wesentlich, daß die die PTC-Widerstände berührenden Blechbänder gut, nach Möglichkeit vollflächig, an den PTC-Widerständen anliegen. Zu diesem Zweck sind in dem Halterahmen Federelemente angeordnet, die über die Lamellen auf die Blechbänder drücken. Es kann dazu vorteilhaft sein, wenn die Blechbänder in dem Halterahmen in gewissem Umfang beweglich gehalten sind, damit die Druckkräfte von den Lamellen ungehindert auf die Blechbänder weitergegeben werden können.PTC resistors are widely used in technology as protective elements in devices in which overheating due to excessive operating current is to be prevented. The abovementioned properties inherent in the PTC resistors must be given particular attention when PTC resistors are used as heating elements, as in the present case. The aforementioned self-regulating property of a PTC resistor leads to the PTC resistor not being able to give off a sufficient amount of heat if the heat it has developed is not dissipated by it. It is therefore here for good heat transfer between the PTC resistor and the medium surrounding it Airflow to worry. The features further characterizing the invention are directed to solving this problem. It is particularly important that the sheet metal strips touching the PTC resistors rest well against the PTC resistors, if possible over the entire surface. For this purpose, spring elements are arranged in the holding frame, which press on the metal strips via the slats. To this end, it can be advantageous if the sheet metal strips are held to a certain extent in the holding frame so that the pressure forces can be passed on to the sheet metal strips unhindered.

Obgleich einleitend insbesondere auf Wärmetauscher in Verbindung mit Brennkraftmaschinen bzw. Kraftfahrzeugen Bezug genommen worden ist, sei betont, daß Radiatoren nach der Erfindung nicht nur für jenen Einsatzzweck geeignet sind, sondern ihnen ein weites Anwendungsgebiet offensteht, insbesondere auch in Hausinstallationen, Haushaltsgeräten und dergleichen.Although in the introduction reference was made in particular to heat exchangers in connection with internal combustion engines or motor vehicles, it should be emphasized that radiators according to the invention are not only suitable for that purpose, but are also open to a wide range of applications, in particular also in domestic installations, household appliances and the like.

Die Erfindung wird nachfolgend unter Bezugnahme auf ein in den Zeichnungen dargestelltes Ausführungsbeispiel näher erläutert. Es zeigt:

  • Fig. 1 einen Radiator nach der Erfindung von der Seite, teilweise geschnitten,
  • Fig. 2 den Radiator nach Fig. 1 von der Stirnseite, und
  • Fig. 3 einen Schnitt durch den Radiator nach Fig. 1 längs der Linie III-III.
The invention is explained in more detail below with reference to an embodiment shown in the drawings. It shows:
  • 1 shows a radiator according to the invention from the side, partially in section,
  • Fig. 2 shows the radiator of FIG. 1 from the front, and
  • Fig. 3 shows a section through the radiator of FIG. 1 along the line III-III.

Die Zeichnung zeigt einen Radiator von der Seite, im oberen Abschnitt längs der Linie I-I von Fig. 3 geschnitten. Der Radiator besteht aus einem Halterahmen 1 aus ersten, längslaufenden Rahmenholmen 2 und zweiten, querlaufenden Rahmenholmen 3, die an ihren Enden miteinander verbunden sind und eine Ebene aufspannen. In der von dem Rahmen 1 aufgespannten Ebene verlaufen parallel zu den ersten Rahmenholmen 2 im vorliegenden Beispiel zwei wärmeabgebende Elemente 4, die jeweils aus zwei Blechbändern 5 bestehen, die parallel zueinander verlaufen und zwischen sich einen Zwischenraum ausbilden, in welchem mehrere PTC-Widerstände 6 angeordnet sind, die mit beiden Seiten an den benachbarten Blechbändern 5 anliegen.The drawing shows a radiator from the side, cut in the upper section along the line I-I of Fig. 3. The radiator consists of a holding frame 1 made of first, longitudinal frame bars 2 and second, transverse frame bars 3, which are connected at their ends and span a plane. In the plane spanned by the frame 1, parallel to the first frame spars 2 in the present example, run two heat-emitting elements 4, each consisting of two sheet metal strips 5, which run parallel to one another and form an intermediate space between them, in which a plurality of PTC resistors 6 are arranged are, which abut the adjacent metal strips 5 with both sides.

Die Blechbänder 5 sind in den zweiten Rahmenholmen 3 voneinander elektrisch isoliert gehalten, und wenigstens zwei von ihnen sind mit elektrischen Anschlußelementen, im vorliegenden Falle mit Flachsteckeranschlüssen 7, versehen, die nach außen über den einen Rahmenholm 3 vorstehen.The sheet metal strips 5 are kept electrically insulated from one another in the second frame spars 3, and at least two of them are provided with electrical connection elements, in the present case with flat plug connections 7, which protrude outward beyond the one frame spar 3.

An die freien, d.h. den PTC-Widerständen 6 abgewandten Flachseiten der Blechbänder 5 stoßen eine Vielzahl planparalleler Lamellen 8 mit ihren Stirnseiten an. Im dargestellten Beispiel erkennt man vier Lamellengruppen, von denen die jeweils außen, d.h. den ersten Rahmenholmen 2 benachbarten Lamellengruppen stirnseitig auch an die genannten Rahmenholme 2 anstoßen, während die innen liegenden Lamellengruppen mit ihren den wärmeabgebenden Elementen 4 abgewandten Stirnseiten an ein Trägerblechband 9 anstoßen, das sich parallel zu den ersten Rahmenholmen 2 in der von dem Halterahmen 1 aufgespannten Ebene zwischen den zweiten Rahmenholmen 3 erstreckt und an einem Ende mit einem elektrischen Anschlußelement, hier in Form eines Flachsteckeranschlusses 10, versehen ist. Auch dieses Halteblechband 9 ist vorzugsweise gegenüber den zweiten Rahmenholmen 3 elektrisch isoliert, muß es aber nicht unbedingt sein, wenn der Halterahmen 1 galvanisch mit der Stromversorgung des Radiators verbunden sein darf.A large number of plane-parallel lamellae 8 abut the free, ie, the PTC resistors 6 facing away from the flat strips 5 with their end faces. In the example shown, four lamella groups can be seen, of which the lamella groups adjacent to the outside in each case, ie the first frame bars 2, also abut the frame bars 2 mentioned on the front side, while the inner lamella groups, with their end faces facing away from the heat-emitting elements 4, abut against a carrier strip 9 extends parallel to the first frame spars 2 in the plane spanned by the holding frame 1 between the second frame spars 3 and is provided at one end with an electrical connection element, here in the form of a flat plug connection 10. This retaining strip 9 is preferably opposite the second Frame bars 3 are electrically insulated, but it does not necessarily have to be if the holding frame 1 may be galvanically connected to the power supply of the radiator.

Die ersten, längslaufenden Rahmenholme 2 bestehen jeweils aus einem mit den Lamellen 8 der äußeren Lamellengruppen in Berührung stehenden inneren Band 11 und einer sich in gleicher Richtung erstreckenden, relativ steifen Schiene 12 von vorzugsweise U-förmigem Querschnitt, die mit dem inneren Band 11 einen Zwischenraum 13 einschließt, in welchem sich ein Federelement, hier in Form eines länglichen, gewellten Federbandes 14 befindet, das sich an der Schiene 12 abstützt und das innere Band 11 gegen die Lamellen 8 drückt.The first, longitudinal frame spars 2 each consist of an inner band 11 in contact with the fins 8 of the outer group of fins and a relatively rigid rail 12, preferably U-shaped in cross section, which extends in the same direction and which has an intermediate space with the inner band 11 13 includes, in which there is a spring element, here in the form of an elongated, corrugated spring band 14, which is supported on the rail 12 and presses the inner band 11 against the slats 8.

Die Lamellen 8 einer äußeren Lamellengruppe können stirnseitig jeweils mit dem inneren Band 11 oder mit dem Blechband 5 fest verbunden sein, beispielsweise durch Löten, oder sowohl mit dem inneren Band 11 als auch mit dem Blechband 5, um eine integrale Einheit zu bilden. Die Lamellen 8 der inneren Lamellengruppen können in gleicher Weise mit dem Trägerband 9 oder mit dem benachbarten Blechband 5 verbunden sein.The lamellae 8 of an outer lamella group can in each case be firmly connected on the end face to the inner band 11 or to the metal band 5, for example by soldering, or both to the inner band 11 and to the metal band 5 in order to form an integral unit. The lamellae 8 of the inner lamella groups can be connected in the same way to the carrier strip 9 or to the adjacent metal strip 5.

Das Trägerband 9 kann gegebenenfalls auch entfallen, so daß der Radiator nur drei Lamellengruppen enthält, oder er kann durch ein weiteres wärmeabgebendes Element aus Blechbändern und PTC-Widerständen ersetzt sein, so daß der Radiator dann drei wärmeabgebende Elemente enthält. Es ist auch möglich, eine größere Vielzahl von wärmeabgebenden Elementen in dem Halterahmen vorzusehen.The carrier tape 9 can optionally be omitted so that the radiator contains only three lamella groups, or it can be replaced by a further heat-emitting element made of sheet metal strips and PTC resistors, so that the radiator then contains three heat-emitting elements. It is also possible to provide a larger number of heat-emitting elements in the holding frame.

Elektrische Spannung kann im dargestellten Beispiel zwischen die Flachsteckeranschlüsse 7 und den Flachsteckeranschluß 10 angelegt werden, so daß die Spannungszuführung zu jeweils einem der Blechbänder 5 über das Trägerband 9 und die zwischen diesem und dem betreffenden Blechband 5 liegenden Lamellen 8 der betreffenden inneren Lamellengruppe erfolgt. Alternativ kann, PTC-Widerstände gleicher Charakteristika vorausgesestzt, Spannung doppelter Größe nur an die Flachsteckeranschlüsse 7 angelegt werden, so daß sich eine elektrische Reihenschaltung ergibt.In the example shown, electrical voltage can be applied between the flat plug connections 7 and the flat plug connection 10, so that the voltage supply to one of the sheet metal strips 5 takes place via the carrier strip 9 and the lamellae 8 of the relevant inner lamella group lying between this and the relevant metal strip 5. Alternatively, provided PTC resistors of the same characteristics are used, voltage of double magnitude can only be applied to the flat plug connections 7, so that an electrical series connection results.

Die PTC-Widerstände 6 können zwischen den Blechbändern 5 durch einen Streifen 15 aus elektrisch isolierendem Material auf Abstand gehalten sein, der passende Druchbrüche 16 zur Aufnahme der PTC-Widerstände 6 enthält, wie dies anschaulich in den Fig. 1 und 3 zu erkennen ist. Es versteht sich, daß dieser Streifen 15 keine größere Dicke haben darf, als die PTC-Widerstände 6, die im dargestellten Beispiel von flacher, scheibenförmiger Gestalt sind.The PTC resistors 6 can be kept at a distance between the metal strips 5 by a strip 15 of electrically insulating material, which contains suitable openings 16 for receiving the PTC resistors 6, as can be seen clearly in FIGS. 1 and 3. It goes without saying that this strip 15 must not have a greater thickness than the PTC resistors 6, which in the example shown are of flat, disk-shaped form.
