Electrical drive assembly for driving e.g. hybrid car, has control unit for actuating electromotor unit, and cooling passages whose transits are provided for passing coolant to cooling passages to form closed cooling circuit

摘要

The assembly (EA1) has a control unit (SE1) for actuating an electromotor unit. A cooling unit (KE11) cools the electromotor unit that comprises a cooling passage (KK11) with an intake port (EO11) and an exhaust opening (AO11) for passing a coolant from the intake port to the exhaust opening. The exhaust opening of the cooling passage and another intake port (EO12) of another cooling passage (KK12) are provided for passing the coolant. Two transits (DG11, DG12) of the cooling passages are provided for passing the coolant to the cooling passages to form a closed cooling circuit.
