Abstract
Heat sink for an electric motor, in particular for a wheel hub drive of a commercial vehicle, with a channel which connects a first connection of the heat sink and a second connection of the heat sink, wherein the channel winds around the heat sink in a spiral. With such a heat sink, a flow condition of coolant within the channel can be generated in which secondary vortices are formed, and the cooling capacity is significantly improved.
