COMPACT UNIT

摘要

The invention relates to a compact unit, at least consisting of an electric motor, which is accommodated in housing parts (7, 55) of a unit housing (45) and which drives at least one hydraulic pump and gives off heat at the same time, an air heat-exchanging device, and a fan (19), which can be driven in order t o produce an air flow. The compact unit is characerized in that a flow-conducting device (47, 55) that divides off from the air flow at least a first partial flow flowing around the electric motor and a second partial flow flowing to the heat-exchanging device is present in the unit housing (45), or that, 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.

主权项

1. A compact unit, at least consisting of
an electric motor (3) accommodated in housing parts (7, 55) of a unit housing (45), which drives at least one hydraulic pump (1) and gives off heat in the process, an air-heat exchanging device (14) and a fan (19), which may be driven to generate an airflow (65),characterized in that a flow conducting means (47, 55) is present in the unit housing (45) which divides the airflow (65) into at least one first partial flow (67), which flows around the electric motor (3) and one second partial flow (69), which flows toward the heat exchanging device (14), or the airflow (65), in succession, flows first toward the electric motor (3) and then toward the heat exchanging device (14), or that the respective flow occurs at least partly in the reverse direction by means of the air flow (65).
