Description

Kühleinrichtung für elektrische Generatoren von Unterwasserkraftwerken Die Erfindung betrifft Kühleinrichtungen für elektrische Generatoren von Unterwasserkraftwerken. Gemäß der Erfindung wird das umlaufende Kühlmittel des Generators zur Rückkühlung (furch das Triebwasser an Innenkühlrippen vorbeigeführt, die in den toten Räumen des tropfenförmig ausgebildeten Generatorgehäuses angeordnet sind. Auf diese Weise wird eine besonders wirksame Kühlung der Maschine erzielt.Cooling device for electrical generators in underwater power plants The invention relates to cooling devices for electrical generators in underwater power plants. According to the invention, the circulating coolant of the generator is used for recooling (for the driving water passed the internal cooling fins in the dead spaces of the drop-shaped generator housing are arranged. In this way a particularly effective cooling of the machine is achieved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Hierbei ist in dein vom L'riehwasser durchflossenen Kanal i mit der Wand 2 der Generator 3 eines Unterwasserkraftwerkes angeordnet, der von der Schraube 4. angetrieben wird und ein tropfenförmiges Gehäuse 3 besitzt. Der Generator ist mit einer Umlaufkühlung ausgestattet, wobei (las Triebwasser als Rückkühlmittel verwendet wird. Gemäß der Erfindung sind in den toten Räumen an beiden Enden (leg Gehäuses 3 Innenkühlrippen 9 und io angeordnet. die die Wärme der an ihnen vorbeistreichenden Kühlluft entnehmen und an (las am Gehäuse vorbeifließende Triebwasser abgeben. Trotz der auf diese Weise erreichten. wesentlichen Verbesserung der Kühlung muß keinerlei Vergrößerung der Anlage in Kauf genommen werden. Wegen der Tropfenforni des Gehäuses ist nämlich viel Platz an dessen Enden im Innern vorhanden. Dieser Platz wird erfindungsgeniiili zur Anordnung der Kühlrippen ausgenutzt. Ferner tritt bei der angeführten Verbesserung der Kühlung keine Erhöhung des Strömungswiderstandes für <las Triebwasser ein, denn es ist weder eine Vergrößerung des Gehäuses noch eine Veränderung des äußeren Querschnittes der Anlage erforderlich. Die anführten hiililrippcii sind nämlich nicht außen. .sondern iiliien am Gehäuse angeetzt.An exemplary embodiment of the invention is shown in the drawing. In this case, the generator 3 of an underwater power station is arranged in the channel i through which L'riehwasser flows, with the wall 2, which generator 3 is driven by the screw 4 and has a drop-shaped housing 3. The generator is equipped with a circulation cooling system, whereby (the head water is used as a return coolant. According to the invention, internal cooling fins 9 and 10 are arranged in the dead spaces at both ends (leg housing 3. In spite of the substantial improvement of the cooling achieved in this way, no enlargement of the system has to be accepted. Because of the drop shape of the housing there is a lot of space at its ends inside. This space is inventive for the arrangement Furthermore, with the mentioned improvement of the cooling, there is no increase in the flow resistance for the headwater, because neither an enlargement of the housing nor a change in the external cross-section of the system is necessary iiliien attached to the housing tzt.
