A cooling device for cooling a stator for an electric machine of a motor vehicle having a coolant-conducting unit and at least one winding groove cooling channel is provided. The coolant-conducting unit and the at least one winding groove cooling channel are connectable to a hollow-cylindrical lamination stack of the stator having, in a circumferential direction, a plurality of winding grooves which extend axially and receive windings of the stator. The coolant-conducting unit is arranged on an end face of the lamination stack, conducts coolant along the end face, and has an inlet for supplying the coolant and an outlet for discharging the coolant, and the at least one winding groove cooling channel extending axially from the coolant unit is arranged in at least one winding groove, conducts the coolant in the at least one winding groove, and is fluid-coupled to the inlet and the outlet.
