Abstract
An annular heat sink for fastening to an outer shell wall of a heat-emitting electric motor includes at least one guide wall portion which is arranged on the annular heat sink and covers portions of at least one flow duct, delimited laterally by peripheral cooling fins, from the outside, in such a way that an air flow which has entered into a flow duct in a first region of a side of the annular heat sink which faces the incoming air is deflected into a second region of a side of the annular heat sink which faces away from the incoming air. The heat sink may be used in an electric motor, which may in turn be used in a drive arrangement.
