1. A drive unit for a drivetrain of an electrically drivable motor vehicle, the drive unit comprising:
a first electric machine having a rotor;
a second electric machine having a rotor;
a housing in which the first electric machine and the second electric machine are arranged at least in some regions;
an output shaft to which the rotor of the second electric machine is connected for conjoint rotation; a disconnect clutch by which the rotor of the first electric machine is connectable to the output shaft for torque transmission;
power electronics configured to control at least one of the two electric machines_, wherein the power electronics are arranged on a radial outer side of the housing;
a flow system configured to implement a flow of a coolant for at least partial cooling of the power electronics; and a heat exchanger adapted to cool the coolant.
