Description

Die Erfindung betrifft einen Kühlradiator gemäß dem Patentanspruch 1.The invention relates to a Kühlradiator according to claim 1.

Beim heutigem Stand der Technik werden Leistungstransformatoren im größerem Leistungsbereich nicht mit einem Wellblechkessel, das heißt, die Wände des Kessels sind als Wellblech direkt Teil des Behälters, auch bekannt aus den Schriften GB 401 278 , GB 2 132 031 A , US 4 589 587 und US 4 469 269 ausgeführt, sondern der Kesselbehälter besteht aus Starkblech und die Kühlung des Aktivteils erfolgt mit an dem Gefäß geflanschten oder geschweißten Kühlradiatoren, auch bekannt aus den Schriften DE 36 27 180 A1 , DE 1 971 624 U, GB 879 200 , GB 498 798 , DE 10 2004 054 180 A1 , DE 964 166 B , US 4 002 200 , CH 424 151 und DE 27 25 64 .In the current state of the art power transformers in the larger power range are not with a corrugated iron boiler, that is, the walls of the boiler are as corrugated metal directly part of the container, also known from the writings GB 401 278 . GB 2 132 031 A . US 4,589,587 and US 4,469,269 executed, but the boiler container is made of heavy plate and the cooling of the active part is done with flanged or welded to the vessel Kühlradiatoren, also known from the Scriptures DE 36 27 180 A1 . DE 1 971 624 U, GB 879,200 . GB 498 798 . DE 10 2004 054 180 A1 . DE 964 166 B . US 4,002,200 . CH 424 151 and DE 27 25 64 ,

Die Kühlflüssigkeit des Transformators erwärmt sich am Aktivteil entlang und fließt durch Schwerkraft oben in den Sammelrohren der Kühlradiatoren, kühlt hier, herunter fließend ab und gelangt unten, über die Kollektoren, wieder in dem Transformator.The cooling liquid of the transformer heats up along the active part and flows by gravity up in the headers of the cooling radiators, cools down here, flowing down and passes down, through the collectors, back into the transformer.

Aus der Vielzahl der vorhin genannten Schriften bekannten Möglichkeiten, haben sich Radiatoren zusammengesetzt aus einzelnen flachen Kühlelementen die hintereinander oben und unten an einem Flüssigkeitskollektor angeschweißt sind und am Transformator angeflanscht werden, heute durchgesetzt.From the variety of the aforementioned fonts known ways, radiators have composed of individual flat cooling elements which are welded one behind the other above and below to a liquid collector and flanged to the transformer, enforced today.

Nachteile der gegebenen Ausführung sind hoher Fertigungskomplexität und das Angebot von festgelegten Normgrößen die einer Optimierung an dem wirklichem Kühlungsbedarf des Transformators vermissen lassen.Disadvantages of the given design are high manufacturing complexity and the offer of fixed standard sizes that can be an optimization to miss the real cooling needs of the transformer.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Radiator für die Kühlung von Transformatoren zu schaffen, mit vereinfachter Fertigungskomplexität, mit verringerter Längen an notwendigen Schweißnähten, größere Flexibilität in der Auswahl der kühlenden Oberflächenmenge und dadurch Einsparung an notwendiger Kühlflüssigkeit.The object of the present invention is to provide a radiator for the cooling of transformers, with simplified manufacturing complexity, with reduced lengths of necessary welds, greater flexibility in the selection of the cooling surface amount and thereby saving on necessary coolant.

Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten des Radiators ergeben sich aus der nachfolgenden Definierung des Erfindungsanspruches und eines Ausführungsbeispieles anhand von Zeichnungen.Other objects, features, advantages and applications of the radiator will become apparent from the following definition of the invention claim and an embodiment with reference to drawings.

In den Zeichnungen zeigen:In the drawings show:

1 die Vorderseite (Längsseite) des Radiators mit dem Wellblech (1), die Kollektoren (3, 4) und die Flansche (5) 1 the front side (long side) of the radiator with the corrugated metal sheet ( 1 ), the collectors ( 3 . 4 ) and the flanges ( 5 )

2 die Seitenansicht des Radiators mit den vorhin genannten Bezugsziffern, zusätzlich Tragblech 2 2 the side view of the radiator with the above-mentioned reference numerals, in addition support plate 2

3 Ausführungsbeispiel des Wellblechs (1) 3 Embodiment of the corrugated sheet ( 1 )

4 Detail der Ausführungsweise mit dem Wellblech (1), Tragblech (2), Kollektor (3), Flansch (5) und den Schweißnähte (6, 7). 4 Detail of the manner of execution with the corrugated metal sheet ( 1 ), Support plate ( 2 ), Collector ( 3 ), Flange ( 5 ) and the welds ( 6 . 7 ).

Die erfindungsgemäße Losung arbeitet mit durchgehendem Wellblech.The solution according to the invention works with continuous corrugated iron.

Der Kühlradiator besteht aus einem Wellblech (1), wobei die beiden Flanken jeder Welle miteinander jeweils oben und unten flüssigkeitsdicht verschweißt (6) sind, und einem Tragblech (2), das an seinem oberen Ende und seinem unteren Ende derart abgekantet ist, dass aus den abgekanteten Bereichen Kollektoren (3, 4) gebildet sind, wobei das Wellblech (1) flüssigkeitsdicht an das Tragblech (2) angeschweißt (7) ist, und wobei die Kollektoren (3, 4) an einer Seite flüssigkeitsdicht verschlossen und an der gegenüberliegenden Seite jeweils mit einem Flansch (5) versehen sind.The cooling radiator consists of a corrugated metal sheet ( 1 ), wherein the two flanks of each shaft are liquid-tight welded to each other at the top and bottom (6), and a support plate ( 2 ), which is bent at its upper end and its lower end in such a way that from the bevelled areas collectors ( 3 . 4 ) are formed, wherein the corrugated metal sheet ( 1 ) liquid-tight to the support plate ( 2 ) ( 7 ), and wherein the collectors ( 3 . 4 ) liquid-tight on one side and each with a flange on the opposite side ( 5 ) are provided.

Diese Ausführung unterscheidet sich wesentlich dadurch vom heutigen Stand der Technik, dass nur zwei Teile den Grundkörper des Kühlradiators ausbilden, das Tragblech (2) und das Wellblech (1). Hierdurch kann die Fertigungsweise vereinfacht werden und Material eingespart werden.This embodiment differs substantially from the state of the art in that only two parts form the main body of the cooling radiator, the support plate ( 2 ) and the corrugated metal sheet ( 1 ). As a result, the manufacturing process can be simplified and material can be saved.
