Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer elektrischen Maschine, insbesondere einem Generator, nach dem Oberbegriff des Anspruchs 1.The Invention is based on an electrical machine, in particular a generator according to the preamble of claim 1.

Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße elektrische Maschine mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass durch die mindestens eine unmittelbar einer jeden Gleichrichterdiode im Minus-Kühlkörper zugeordneten Kühlungsbohrung die Kühloberfläche direkt an der Gleichrichterdiode erhöht wird und durch den direkten, ungedrosselten und nicht umgelenkten Luftstrom durch die mindestens eine Kühlungsbohrung die Kühlungseffizienz deutlich gesteigert wird. Gleichzeitig werden die Strömungsdruckverluste durch das Vorsehen und Platzieren der Kühlungsbohrungen wesentlich verringert.The inventive electric machine with the Features of claim 1 has the advantage that by at least one directly from each rectifier diode in the minus heatsink associated cooling hole the cooling surface is increased directly at the rectifier diode and by the direct, unthrottled and undeflected airflow through the at least one cooling hole the cooling efficiency is significantly increased. At the same time the flow pressure losses through the provision and placement of the cooling holes essential reduced.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegeben elektrischen Maschine möglich.By the measures listed in the further claims are advantageous developments and improvements in the claim 1 specified electrical machine possible.
