HYBRID-TYPE WORK MACHINE

摘要

The present invention comprises: an electric motor (12) that generates power as a result of being driven by an engine (8) or that assists the engine (8) as a result of being supplied with electric power; a heat exchange device (13) that is supplied with cooling air by a cooling fan (8A); a heat exchange device upstream chamber (28) that is positioned further to an upstream side than the heat exchange device (13) with regard to the flow direction of the cooling air that is supplied to the heat exchange device (13); a power storage device (30) that is charged with or discharges electric power; and an inverter device (34) that controls the activity of the electric motor (12). In addition, a power storage device radiator (42) that cools the power storage device (30) and an inverter radiator (46) that cools the inverter device (34) are separately and independently provided, the power storage device radiator (42) and the inverter radiator (46) being arranged inside the heat exchange device upstream chamber (28) so as to be aligned between the heat exchange device (13) and the power storage device (30).
