Die Erfindung geht aus von einer elektrischen Maschine nach der Gattung des Hauptanspruchs.The invention relates to an electric machine according to the preamble of the main claim.
Es ist schon eine elektrische Maschine aus der
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße elektrische Maschine mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass die Wärmeübertragung weiter verbessert wird, indem die Wärmeübertragungsmittel mit ihrer Längserstreckung in radialer Richtung bezüglich einer Maschinenachse von einer Innenseite des Kühlkanals ausgehend bis an eine Außenseite des Kühlkanals verlaufen. Die Wärmeübertragungsmittel erhöhen abhängig von der Kanalhöhe die Fläche der Innenseite des Kühlkanals. Außerdem ergibt sich durch die mechanische Verbindung eine thermische Anbindung der Außenseite mit der Innenseite des Kühlkanals, und zwar abhängig von der Querschnittsfläche der Wärmeübertragungsmittel, der Wärmeleitfähigkeit des Gehäusematerials und der Anzahl und Lage der Verbindungen. Durch die Erhöhung der effektiven Kühlfläche wird die Kühlung der elektrischen Maschine verbessert.The electric machine according to the invention with the characterizing features of the main claim has the advantage that the heat transfer is further improved by the heat transfer means extending with its longitudinal extent in the radial direction with respect to a machine axis from an inner side of the cooling channel up to an outer side of the cooling channel. The heat transfer means increase the area of the inside of the cooling channel depending on the channel height. In addition, due to the mechanical connection, a thermal connection of the outside to the inside of the cooling channel, depending on the cross-sectional area of the heat transfer medium, the thermal conductivity of the housing material and the number and location of the compounds. By increasing the effective cooling surface, the cooling of the electric machine is improved.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen elektrischen Maschine möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim electrical machine are possible.
Besonders vorteilhaft ist, wenn die Wärmeübertragungsmittel stegförmig oder säulenförmig ausgeführt und von der Strömung in Umfangsrichtung der elektrischen Maschine umströmbar sind.It is particularly advantageous if the heat transfer means are web-shaped or column-shaped and can be flowed around by the flow in the circumferential direction of the electric machine.
Gemäß einer vorteilhaften Ausführung sind die Wärmeübertragungsmittel im Querschnitt trapezförmig, kreisförmig, ovalförmig, rechteckförmig, viereckförmig oder vieleckförmig ausgeführt.According to an advantageous embodiment, the heat transfer means are trapezoidal, circular, oval, rectangular, quadrangular or polygonal shaped in cross section.
