Description

Kühleinrichtung für geschlossene, oberflächengekühlte elektrische Maschinen Für die Abführung der Verlustwärme bei geschlossenen elektrischen Maschinen hat man nicht nur die Gehäuse mit Kühlrippen versehen und die so vergrößerte Oberfläche mittels eines Außenkühlluftstroms gekühlt, sondern auch den Innenkühlluftstrom durch zwischen den außenliegenden Kühlrippen angeordnete Rohre geleitet und so den Außenluftstrom sowohl zur Oberflächenkühlung als auch zur Kühlung der Innenluft herangezogen.Cooling device for closed, surface-cooled electrical Machines For the dissipation of heat loss in closed electrical machines Not only did the housing have cooling fins and the increased surface area cooled by means of an external cooling air flow, but also through the internal cooling air flow pipes arranged between the external cooling fins and thus the flow of outside air used both for surface cooling and for cooling the interior air.

Es ist Aufgabe der Erfindung, die Kühlwirkung bei derartigen Maschinen weiterzusteigern. Erfindungsgemäß sind an den beiden Stirnseiten des Gehäuses Leitvorrichtungen angeordnet, durch welche die von der einen Stirnseite der Maschine angesaugte Außenluft in bekannter Weise zwischen längs der Gehäuseoberfläche angeordnete Kühlrippen und die von der anderen Stirnseite angesaugte Außenluft durch Kanäle innerhalb eines außerhalb des Kühlrippenbereichs das Gehäuse umgebenden Ringkanals für den Innenluftstrom geführt ist. Die Leitvorrichtungen sind zweckmäßig wenigstens zum Teil von den beiden Lagerschilden gebildet. Ein vorteilhafter. Aufbau der Maschine ergibt sich, wenn wenigstens ein Teil der 'Kühlrippen an den beiden Enden schlaufenförmig erweitert ist und die Satrlaufenöffrnurbgen Verbindungskanäle zwischen dem Gehäuseinnenraum und dem Ringkanal für die Innenluft bilden.It is the object of the invention to improve the cooling effect in such machines to keep increasing. According to the invention, guide devices are provided on the two end faces of the housing arranged through which the outside air sucked in from one end of the machine in a known manner between cooling fins and arranged along the housing surface the outside air sucked in from the other end face through ducts within a outside of the cooling fin area, the ring channel surrounding the housing for the internal air flow is led. The guiding devices are expediently at least in part of the two End shields formed. An advantageous one. The structure of the machine arises when at least a part of the 'cooling fins at the two ends expanded in a loop shape is and the Satrlaufenöffrnurbgen connecting channels between the housing interior and form the ring channel for the indoor air.

Die Erfindung soll an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden: Die Maschine besteht im wesentlichen aus dem Gehäuse t, den Lagerschilden 2 und 3 mit den Gleitlagern 4 und 5, der Welle 6; dem Ständerblech- The invention will be explained in more detail with reference to the embodiment shown in the drawing: The machine consists essentially of the housing t, the end shields 2 and 3 with the plain bearings 4 and 5, the shaft 6; the stand sheet
