Abstract
Description
Verfahren zur Herstellung von stirnseitigen Werbindungen paralleler rohrähnlicher Körper Die Erfindung bezieht sich auf ein Verfahren zum luft- und/oder wasserdichten Verbinden der Stirnflächen mehrerer im wesentlichen paralleler, rohrähnlicher Körper deren stirnseitig offenbleibende Enden in ungefähr der gleichen Ebene liegen. Process for the production of frontal advertisements parallel tube-like body The invention relates to a method for air and / or watertight connection of the end faces of several substantially parallel, pipe-like Body whose ends remaining open at the front are in approximately the same plane.
Ein derartiges Verfahren wird z.B. bei der Herstellung von Wärmeaustauschern für elektrische Maschinen angewendet, bei denen durch die rohrähnlichen Körper ein Kühlmittel und zwischen diesen Körpern ein weiteres, von dem ersten zu trennendes Kühlmittel strömt und durch die Wandungen der rohrähnlichen Körper ein Wärmeaustausch stattfindet. Grundvoraussetzung für ein ordnungsgemäßes Sunktionieren eines solchen Wärmeaustauschers ist eine vollkommene Abdichtung der Strömungswege des einen von denen des anderen Kühlmittels. Ein Abdichtungsproblem tritt insbesondere an den stirnseitigen Enden der parallelen rohrähnlichen Körper auf.Such a process is used, for example, in the manufacture of heat exchangers Applied to electrical machines where through the pipe-like body a Coolant and between these bodies another one to be separated from the first Coolant flows and heat exchanges through the walls of the tube-like body takes place. Basic requirement for such a system to function properly Heat exchanger is a perfect seal of the flow paths of one of those of the other coolant. A sealing problem occurs particularly at the front ends of the parallel tube-like body.
Während die Enden der rohrähnlichen Körper für das eine Kühlmittel oflen gehalten werden sollen, müssen die zwischen den Enden gelegerlerl Häume abgedichtet werden. Das Abdichten wird nach dem aLiemtinen Stand der 'l'echrlik bislang durch entsprechend gelochte querbleche erreicht, an welche die einzelnen rohrähnlichen Körper dicht angeschlossen werden müssen. Dieser Verfahrensschritt ist rniihsarn, zeitraubend unci erfordert ein sehr genaues Beinhalten der Längentoieranzen der rohrähnlichen körper.While the ends of the pipe-like body for the one coolant are to be kept open, the spaces between the ends must be sealed will. Sealing has been carried out according to the aLiemtinen state of the 'l'echrlik so far correspondingly perforated cross-sheets to which the individual pipe-like Body must be tightly connected. This process step is rniihsarn, time-consuming and requires a very precise observation of the lengthways of the tube-like body.
Der Erfindung liegt die Aufg@be zugrunde, ein Verfahren anzugeben, welches auf einfache Weise ein dichtes stiruseitiges-Verbinden der offenbleibenden Rohrenden ermöglicht und gleichzeitig größere Toleranzen bezüglich der einzelnen Längen der rohrälinlichen Körper zuläßt.The invention is based on the object of specifying a method which, in a simple way, allows the remaining open Allows pipe ends and at the same time greater tolerances with respect to the individual Lengths of the tubular body allows.
Diese Aufgabe wird für ein Verfahren der eingangs angegebenen Art dadurch gelöst, daß die rohrähnlichen Körper mit einer ihrer Stirnseiten auf eine mit einer Trennfolie abgedeckte, auf einer Richtfläche liegende Schaumstoffmatte gestellt werden und dann unter Verwendung eines Gießrahmens der stirnseitige Raum zwischen den Körpern in der gewünschten Höhe mit einer geeigneten Vergußmasse ausgegossen wird, worauf die Vergußmasse ausgehärtet und dann die Schaumstoffmatte mit der Trennfolie entfernt wird.This task is carried out for a method of the type specified at the beginning solved in that the tube-like body with one of their end faces on a Foam mat covered with a separating film and lying on a leveling surface and then the frontal space using a casting frame Poured between the bodies at the desired height with a suitable potting compound is, whereupon the potting compound cured and then the foam mat with the release film Will get removed.
Durch das Gewicht der rohrähnlichen Körper wird die Schaumstoffmatte samt der darüberliegenden Trennfolie kalottenförmig eingedrückt. Es entsteht an diesen Stellen trotz größerer 'Doleranzen in der Länge der rohrähnlichen Körper jeweils ein dichter Äbschluß, so daß die Vergußmasse die Enden der Körper dicht umgibt, ohne diefreizuhaltenden Öffnungen erreichen zu können.The weight of the pipe-like body makes the foam mat together with the separating film above, pressed in in the shape of a dome. It arises on these places despite larger 'tolerances in the length of the pipe-like body in each case a tight seal so that the casting compound tightly seals the ends of the body surrounds without being able to reach the openings to be kept free.
In zweckmäßiger Ausgestaltung des Verfahrens wird als Gießrahmen eine Rahmenkonstruktion verwendet, welche die rohrähnlichen Körper als mechanische Abstützung umgibt. Eine derartige Rahmenkonstruktion wird nämlich ohnehin zumeist zur mechanischenÄbstützung der rohrähnlichen Körper vorhanden sein, so daß ein spezieller Gießrahmen eingespart werden kann.In an expedient embodiment of the method, a casting frame is used Frame construction used which the pipe-like body as mechanical support surrounds. A frame construction of this type is usually used for mechanical support anyway the pipe-like body must be present, so that a special casting frame is saved can be.
Zur besseren mechanischen Festigkeit ist es ach vorteilhaft, die rohrähnlichen Körper vor dem Verfahren teilweise direkt untereinander fest zu verbinden, E-rozgt dieses teilweise durch gehend über die gesamte Länge der Körper, so entstehen einzelne rascI1en, welche für einen Wärmeaustauscher iii i'ashenkülilerbautorm charakteristisch sind.For better mechanical strength, it is also advantageous to use the pipe-like Before the procedure, some of the bodies have to be firmly connected directly to one another, E-rozgt this partly going through the entire length of the body, so individual ones are created rascI1en, which is characteristic of a heat exchanger iii i'ashenkülilerbautorm are.
Äs trennfolie haben sich eine Folie aus Polyäthylen und als Vergußmasse ein kaithärtendes IIarz als besonders vorteilhaft erwiesen insbesondere wenn der Vergußmasse ein Füllstoff, z.I3.Äs separating film have a film made of polyethylene and as a potting compound a hardening resin proved to be particularly advantageous, especially when the Potting compound a filler, e.g. I3.
Quarzmehl, beigefügt wird.Quartz flour, is added.
Das Verfahren nach der Erfindung soll anhand der Zeichnung im folgenden näher erläutert werden: Die figur zeigt einen Schnitt durch die rohrähnlichen Körper 1, welche mit einer ihrer offenzuhaltenden Stirnseiten auf eine Schaumstoffmatte 5 gestellt sind. Die Schaumstoffmatte selbst liegt auf einer Richtfläche 6 und ist von den rohrähnlichen körpern 1 durch die trennfolie 4 (hier stark übertrieben dick aufgezeigt) getrennt. Der stirnseitige Raum zwischen den rohrähnlichen Körpern 1 wird von einem Gießrahmen 2 umgeben. In die Zwischenräume zwischen den rohrähnlichen Körpern wird nun die Vergußmasse 5 gegossen, bis diese eine ausreichende erwünschte flöhe hat. Der Gießrahmen 2, welcher gleichzeitig als Rahmenkonstruktion zur mechanischen Stützung der rohrähnlichen Körper 1 dient, verhindert ein seitliches Jierauslaufen der Vergußmasse 3.The method according to the invention will be based on the drawing below to be explained in more detail: The figure shows a section through the pipe-like body 1, which with one of its end faces to be kept open on a foam mat 5 are set. The foam mat itself lies on a straightening surface 6 and is from the pipe-like bodies 1 through the separating film 4 (here greatly exaggerated thick shown) separately. The frontal space between the pipe-like bodies 1 is surrounded by a casting frame 2. In the spaces between the pipe-like Bodies, the casting compound 5 is now poured until this is a sufficient desired has fleas. The casting frame 2, which at the same time as a frame structure for the mechanical Serves support of the pipe-like body 1, prevents a sideways leakage the potting compound 3.
Durch die '?rennfolie 4 wird gleichzeitig ein Eindringen der Vergußmasse 3 (vorzugsweise eines kalthärtc-nden Kunstharzes) in die Schaumstoffmatte 5 vermieden. ach dem Aushärten der Vergußmasse 3 wird dann die Schaumstoffmatte 5 mit der Treniifolie 4 entfernt.At the same time, penetration of the potting compound occurs through the separation film 4 3 (preferably a cold-curing synthetic resin) avoided in the foam mat 5. After the potting compound 3 has hardened, the foam mat 5 is then covered with the film 4 removed.
Die gegenüberliegenden Stirnseiten der rohrähnlichen Körper 1 werden in gleicher Weise verbunden und abgedichtet.The opposite end faces of the pipe-like body 1 are connected and sealed in the same way.
Vorteilhaft können damit auf einfache Weise die rohrähnlichen Körper 3 verbunden werden, wobei gleichzeitig trotz eventueller größerer längentoleranzen der Raum zwischen den Körpern 3 sicher von deren offenbleibenden Enden abgedichtet wird.The pipe-like bodies can thus be advantageous in a simple manner 3 are connected, at the same time despite possible larger length tolerances the space between the bodies 3 is securely sealed by their open ends will.
