Abstract (en)
[origin: WO2020057699A1] The invention relates to a cooling element for an electric motor, particularly for a wheel hub drive, having a channel, which connects a first connection of the cooling element and a second connection of the cooling element, wherein the channel winds in a spiral around the cooling element. According to the invention, such a cooling element allows a flow state of coolant within the channel to be generated in which secondary turbulences are formed and the cooling performance is significantly improved.
