Description
Die Erfindung betrifft einen Kühlradiator, insbesondere einen Kühlradiator eines Kessels eines Transformator-Aktivteils, wobei der Kühlradiator mit von der am Aktivteil erwärmten Kühlflüssigkeit durch Schwerkraft von oben über ein Sammel-bzw. Verteilerrohr, einen so genannten Sammler, nach unten zu einem Unterverteiler bzw. -sammler, einem so genannten unteren Sammler, durchströmenden Kühlelementen ausgebildet ist, wobei die gekühlte Flüssigkeit über den Unterverteiler zurück in den Transformator gelangt und wobei zumindest ein Kühlradiator entfernt von oder direkt am Transformator bzw. dessen Kessel angeordnet ist.The invention relates to a Kühlradiator, in particular a Kühlradiator a boiler of a transformer active part, wherein the Kühlradiator with the heated by the active part cooling liquid by gravity from above via a collection or. Distributor tube, a so-called collector, down to a sub-distributor or collector, a so-called lower collector, flowing through cooling elements is formed, wherein the cooled liquid passes through the sub-manifold back into the transformer and wherein at least one Kühlradiator removed from or directly on Transformer or its boiler is arranged.
Kühlradiatoren dieser Art umfassen neben dem oberen und dem unteren Sammler wenigstens ein Teilmodul von Kühlelementen, die über jeweilige Einzelverteilerrohre mit dem oberen bzw. unteren Sammler verbunden sind, wobei die Teilmodule Rohre aufweisen, die an ihrer Außenseite jeweils mit Rippen versehen sind.Cooling radiators of this type comprise in addition to the upper and the lower collector at least a sub-module of cooling elements, which are connected via respective individual manifolds to the upper and lower collector, wherein the sub-modules have tubes which are provided on their outer side with ribs.
Die Kühlelemente von Transformatoren oder anderen elektrischen Geräten bestehen aus flachen, in der Regel von Öl als Kühlflüssigkeit durchströmten Kühlelementen oder aus einem Wellblech, wie durch die
Demgegenüber soll die Herstellung bei gleichzeitig gas- bzw. öldichter Verbindung der Kühlelemente mit den Sammlern vereinfacht und insbesondere der Wärmeübergang bzw. die Wärmeübertragung verbessert werden.In contrast, the production is to be simplified at the same time gas or oil-tight connection of the cooling elements with the collectors and in particular the heat transfer and the heat transfer can be improved.
Es war daher eine Aufgabe der Erfindung, einen Kühlradiator zur Verfügung zu stellen, der einerseits einen einfachen Aufbau aufweist und andererseits einen erhöhten Wärmeübergang bei gleichen Außenmaßen des Kühlradiators insgesamt gewährleistet. Diese Aufgabe wird im erfindungsgemäßen Sinne mit einem Kühlradiator, umfassend die Merkmale des Anspruchs 1, gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen dargelegt.It was therefore an object of the invention to provide a Kühlradiator available, on the one hand has a simple structure and on the other hand ensures increased heat transfer at the same outer dimensions of the Kühlradiators total. This object is achieved in the sense of the invention with a Kühlradiator, comprising the features of claim 1. Advantageous embodiments of the invention are set forth in the dependent claims.
Im erfindungsgemäßen Sinne sind die Teilmodule senkrecht und quer zur Längsrichtung der Sammler angeordnet, wobei die Rohre der Teilmodule zum Luftdurchtritt mit einem Abstand zueinander parallel angeordnet sind. Hierdurch wird ein Kühlradiator geschaffen, der aus mehreren in einer Reihe aufeinander bzw. hintereinander folgend und mit einem Luftspalt zueinander, in Durchbrüchen des oberen Sammelrohres und des Untersammlers eingefügt, einen besonders guten Luftdurchtritt durch den Kühlradiator insgesamt und an den jeweiligen Kühlelementen erlaubt.In the sense of the invention, the sub-modules are arranged perpendicularly and transversely to the longitudinal direction of the collectors, wherein the tubes of the sub-modules for air passage are arranged parallel to one another at a distance from one another. In this way, a Kühlradiator is created, which consists of several in a row successively and successively and with an air gap to each other, inserted into openings of the upper header and the sub collector, a particularly good air passage through the Kühlradiator total and allowed at the respective cooling elements.
Somit tragen sämtliche Kühlelemente des Kühlradiators vorzugsweise gleichwertig zum Wärmeübergang aus dem durch den Kühlradiator hindurchströmenden Kühlmedium, vorzugsweise Öl, in die Umgebungsluft, die den Kühlradiator durchströmt, bei. Im Ergebnis wird eine besonders hohe Energieabfuhr von bis zu 38,00 kW/h vorzugsweise bis zu 39,80 kW/h bei einem Kühlradiator mit einer Breite von bis zu 540 mm, vorzugsweise bis zu 520 mm, und einer Höhe von bis zu 2 m, vorzugsweise bis zu 1,80 m, bewirkt. Bevorzugt wird ein Kühlradiator mit einer Höhe von 0,5 m bis zu 3,60 m. Bei optimierten Querschnitten sowohl des oberen als auch des unteren Sammlers sowie der Rohre der jeweiligen Teilmodule kann eine Durchflussmenge von Öl durch den Kühlradiator von bis zu 2 700 kg/h, vorzugsweise bis zu 2 800 kg/h, erreicht werden.Thus, all of the cooling elements of the cooling radiator preferably carry the heat transfer from the cooling medium flowing through the cooling radiator, preferably oil, into the ambient air flowing through the cooling radiator. As a result, a particularly high energy dissipation of up to 38.00 kW / h, preferably up to 39.80 kW / h with a Kühlradiator having a width of up to 540 mm, preferably up to 520 mm, and a height of up to 2 m, preferably up to 1.80 m causes. Preferred is a Kühlradiator with a height of 0.5 m up to 3.60 m. With optimized cross-sections of both the upper and the lower header and the tubes of the respective sub-modules, a flow rate of oil through the Kühlradiator of up to 2 700 kg / h, preferably up to 2 800 kg / h, can be achieved.
Wie sich durch Versuche bestätigt hat, erfährt die die Rohre von oben nach unten mit bester Kühlwirkung durchfließende Flüssigkeit, insbesondere Öl, einen geringsten Widerstand, wenn ein optimierter Querschnitt der Elemente des Kühlradiators eingehalten wird. Da nur geringstmögliche Widerstände auftreten, kann das System in freier Konvektion arbeiten; es sind keine Pumpen erforderlich.As has been confirmed by experiments, the liquid passing through the pipes from top to bottom with the best cooling effect, in particular oil, experiences the least resistance, if an optimized cross section of the elements of the cooling radiator is maintained. Since only minimal resistance occurs, the system can operate in free convection; no pumps are required.
Der Kühlradiator liegt somit als kompakte Komplett-Einheit vor, die aus gewünscht vielen, im Abstand zueinander angeordneten, über die Einzelverteilerrohre an die Sammler angebundenen Teilmodulen besteht. Der komplette Kühlradiator bzw. dessen Teilmodule können sowohl in Quer- als auch in Längsrichtung von der Umgebungsluft, ggf. unterstützt von Lüftern / Ventilatoren, vollständig umströmt werden. Die Abkühlung bzw. der Wärmeabtrag / der Wärmeübergang wird dadurch sehr effizient gehalten.The Kühlradiator thus exists as a compact complete unit, which consists of many desired, spaced apart, connected via the individual distribution pipes to the collector submodules. The complete Kühlradiator or its sub-modules can be completely flowed around in both the transverse and in the longitudinal direction of the ambient air, possibly supported by fans / fans. The cooling or heat removal / heat transfer is thereby kept very efficient.
Ein bevorzugter Vorschlag sieht vor, dass die Rohre und auch die Sammler, vorzugsweise der obere und der untere Sammler, sowie ebenfalls die Einzelverteilerrohre aus einem durch Strangpressen verarbeitbaren Werkstoff bzw. Material bestehen, wie insbesondere Aluminium bzw. Aluminiumlegierungen, Magnesium oder dergleichen zum Strangpressen geeignete Leichtmetalle. Diese Werkstoffe haben einerseits gute Wärmeübergangseigenschaften und sind andererseits durch sich bildende Oxidschichten korrosionsbeständig, so dass eine Lackierung oder dergleichen Beschichtung bzw. Oberflächenbehandlung entfallen kann, und lassen sich zudem einfach herstellen, nämlich vorzugsweise mit gewünschter, beliebiger Geometrie strangpressen.A preferred proposal provides that the tubes and also the collector, preferably the upper and the lower collector, as well as the individual distribution pipes consist of a processable by extrusion material or material, such as in particular aluminum or aluminum alloys, magnesium or the like for extruding suitable light metals. On the one hand, these materials have good heat transfer properties and, on the other hand, are resistant to corrosion by forming oxide layers, so that coating or similar coating or surface treatment can be dispensed with, and moreover can be easily produced, namely preferably by extrusion with the desired, arbitrary geometry.
Die zur Verbindung der einzelnen Komponenten des Kühlradiators erforderlichen Durchbrüche werden vorzugsweise durch Fräs- oder Laserbearbeitung präzise hergestellt, so dass sich exakte Fügestellen zur Mikrofügung durch bevorzugt Laserschweißen mit gas bzw. öldichter Verbindung erreichen lassen.The openings required for the connection of the individual components of the cooling radiator are preferably produced precisely by milling or laser machining, so that exact joints for microfluidization can be achieved by preferably laser welding with gas or oil-tight connection.
Es wird bevorzugt, wenn jedes Teilmodul bis zu 12, vorzugsweise bis zu 10 Rohre, umfasst. Hierdurch wird ein Kühlradiator geschaffen, dessen Wirkoberfläche mit besonders einfachen Mitteln und ggf. vollständig von der Umgebungsluft umströmbar auf die vom Kühlradiator geforderten Eigenschaften anpassbar ist.It is preferred if each sub-module comprises up to 12, preferably up to 10 tubes. In this way, a cooling radiator is provided, the effective surface of which can be adapted to the required properties of the cooling radiator by means of particularly simple means and, if appropriate, can be completely adapted to be flowed around by the ambient air.
Es wird in diesem Zusammenhang auch bevorzugt, wenn die Rohre der jeweiligen Teilmodule einen abgeflachten, vorzugsweise rechteckigen Querschnitt, insbesondere einen rechteckigen Querschnitt mit abgerundeten Ecken, aufweisen. Besonders bevorzugt wird, wenn derartige Rohre wenigstens einen Innensteg, vorzugsweise zwei Innenstege, aufweisen. Die Breite der Rohre beträgt dabei bevorzugt bis zu 130 mm, vorzugsweise bis zu 120 mm. Insbesondere wird bevorzugt, wenn der Abstand der Rohre zueinander je Teilmodul bis zu 30 mm, vorzugsweise bis zu 27 mm beträgt. Hierdurch wird ein Kühlradiator geschaffen, der einerseits einen ausreichenden Durchfluss von Kühlmedien wie Öl durch die Rohre jedes Teilmoduls ermöglicht und andererseits Rohre mit ausreichender Formstabilität zur Verfügung stellt. Schlussendlich wird durch die Wahl des bevorzugten Abstands zwischen den Rohren ein optimaler Luftdurchtritt durch den Kühlradiator insgesamt bewirkt, wodurch die Kühlleistung optimiert werden kann.It is also preferred in this context if the tubes of the respective sub-modules have a flattened, preferably rectangular cross-section, in particular a rectangular cross-section with rounded corners. It is particularly preferred if such tubes have at least one inner web, preferably two inner webs. The width of the tubes is preferably up to 130 mm, preferably up to 120 mm. In particular, it is preferred if the distance of the tubes from one another per sub-module is up to 30 mm, preferably up to 27 mm. As a result, a Kühlradiator is created on the one hand allows a sufficient flow of cooling media such as oil through the tubes of each sub-module and on the other hand provides tubes with sufficient dimensional stability. Finally, by choosing the preferred distance an optimal air passage through the Kühlradiator effected overall between the tubes, whereby the cooling performance can be optimized.
Es wird überdies bevorzugt, wenn die an der Außenseite der Rohre vorgesehenen Rippen Längsrippen sind, die sich vorzugsweise über die gesamte Länge der Rohre, somit im Wesentlichen über die gesamte Länge des Kühlradiators insgesamt, erstrecken. Es wird insbesondere bevorzugt, wenn bis zu 15, überaus bevorzugt bis zu 12, Längsrippen je Rohr vorgesehen sind. In diesem Zusammenhang wird insbesondere bevorzugt, wenn die Längsrippen eine Höhe, somit eine Erstreckung von der Außenseite des Rohrs nach außen, von bis zu 15 mm, vorzugsweise bis zu 12 mm, aufweisen. Der Abstand der Längsrippen zueinander sollte bis zu 25 mm, vorzugsweise bis zu 20 mm betragen, um hierdurch nicht nur eine Wirkoberfläche für den Kühlradiator mit einer großen Wärmeabstrahlung zu gewährleisten, sondern gleichzeitig auch den Übergang der Wärme aus dem Kühlmedium in die den Kühlradiator umströmende und durchströmende Umgebungsluft zu optimieren.It is furthermore preferred if the ribs provided on the outside of the tubes are longitudinal ribs which preferably extend over the entire length of the tubes, thus substantially over the entire length of the cooling radiator as a whole. It is particularly preferred if up to 15, most preferably up to 12, longitudinal ribs per tube are provided. In this context, it is particularly preferred if the longitudinal ribs have a height, thus an extent from the outside of the tube to the outside, of up to 15 mm, preferably up to 12 mm. The distance between the longitudinal ribs to each other should be up to 25 mm, preferably up to 20 mm, to thereby ensure not only an effective surface for the Kühlradiator with a large heat radiation, but at the same time the transition of heat from the cooling medium in the cooling radiator around and to optimize the flow of ambient air.
Es wird in einer weiteren Ausführungsform der Erfindung bevorzugt, wenn bis zu 10, vorzugsweise bis zu 8, Teilmodule im Kühlradiator vorgesehen sind. Diese Teilmodule, die jeweils über ein oberes und ein unteres Einzelverteilerrohr miteinander verbunden sind, bieten somit eine besonders große Wirkfläche bei gleichzeitig kompakter Bauart des Kühlradiators.It is preferred in a further embodiment of the invention, if up to 10, preferably up to 8, submodules are provided in Kühlradiator. These sub-modules, which are connected to each other via an upper and a lower single distribution pipe, thus offer a particularly large effective area with a compact design of Kühlradiators.
In diesem Zusammenhang wird auch bevorzugt, wenn zumindest der obere Sammler, bevorzugt auch der untere Sammler, einen rechteckigen Querschnitt, vorzugsweise mit einem Maß von 20 x 80 mm Querschnittsfläche, aufweist. Überaus bevorzugt wird zudem, wenn zumindest der obere Sammler, vorzugsweise sowohl der obere als auch der untere Sammler, an einem Ende der Einzelverteilerrohre angeordnet sind und somit nicht den insbesondere von unten nach oben durch den Kühlradiator entlang der Teilmodule entlangströmenden Luftstrom behindert. Allein durch die Anordnung des oberen Sammlers entfernt von der Mitte der Einzelverteilerrohre auf deren Ende hin konnte nachweislich um 38 % verbesserter Luftzutritt zu dem Kühlradiator und Luftaustritt aus dem Kühlradiator erreicht werden.In this context, it is also preferred if at least the upper collector, preferably also the lower collector, has a rectangular cross-section, preferably with a dimension of 20 × 80 mm cross-sectional area. Moreover, it is highly preferred if at least the upper header, preferably both the upper and the lower header, are arranged at one end of the individual distribution pipes and thus do not hinder the air flow flowing along, in particular, from bottom to top through the cooling modules along the submodules. Only by the arrangement of the upper collector away from the middle of the individual manifolds on the end towards could be achieved by 38% improved air access to the Kühlradiator and air leakage from the Kühlradiator.
Eine bevorzugte Ausführung sieht eine vorzufertigende Bauweise des Kühlradiators vor, bei der der obere und der untere Sammler in einer Längserstreckung angeordnet sind und über ihre Länge gesehen im Abstand hintereinander liegend eine beliebige Anzahl von Durchbrechungen aufweisen, bei ovalen Rohren als Kühlelement entsprechend formangepasste, quer zur Längserstreckung vorgesehene Langlöcher. Die Kühlelemente werden zu einem Teilmodul in Durchbrechungen von mit dem oberen und dem unteren Sammler verbundenen Einzelverteilerrohren, diese besitzen wie vorteilhaft auch die Sammler ein Rechteck- oder Quadratformat, eingefügt. Die aus dem oberen und dem unteren Einzelverteiler mit den eingefügten Kühlelementen bestehenden Teilmodule werden mit ihren Einzelverteilerrohren quer zu den Sammlern verlaufend und mit einer ihrer Durchbrechungen in Strömungsverbindung mit einer Durchbrechung der Sammler stehend öldicht mit den Sammlern verbunden, vorzugsweise laserverschweißt, und zwar derart, dass die Sammler die quer dazu angeordneten Teilmodule überbrücken, entweder mittig oder bevorzugt zur Seite und auf die Enden der Einzelverteilerrohre hin versetzt.A preferred embodiment provides a prefabricated construction of the Kühlradiators, in which the upper and lower collectors are arranged in a longitudinal extension and seen over their length at a distance lying behind each other have any number of openings, in oval tubes as a cooling element according to form-fitting, transverse to Longitudinal slotted holes provided. The cooling elements are a sub-module in openings of connected to the upper and lower collector manifolds, these have as advantageous and the collector a rectangular or square format inserted. The existing from the upper and lower manifolds with the inserted cooling elements sub-modules are connected with their individual distribution pipes transversely to the collectors and connected with one of their openings in fluid communication with an opening of the collector standing oil-tight with the collectors, preferably laser welded, in such a way that the collectors bridge the sub-modules arranged transversely thereto, either centrally or preferably offset to the side and towards the ends of the individual distribution pipes.
