Title:
COMPACT UNIT COMPRISING AN ELECTRIC MOTOR AND HYDRAULIC PUMP
Document Type and Number:
WIPO Patent Application WO/2015/124248
Kind Code:
A3
Abstract:
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 to produce an air flow. The compact unit is characterized 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.
