Abstract: A compact unit has an electric motor accommodated in housing parts (7, 55) of a unit housing (45) and driving at least one hydraulic pump and giving off heat at the same time, an air heat-exchanging device, and a fan (19) drivable to produce an air flow. A flow-conducting device (47, 55) divides the air flow at least in a first partial flow flowing around the electric motor and a second partial flow flowing to the heat-exchanging device in the unit housing (45). Alternatively, arranged in series, the air flow first flows against the electric motor and then the heat-exchanging device, or that the incidence of the air flow occurs at least partially in the reverse direction.
