An electric hydraulic shovel (1) is provided with a heater core (34) for heating, an electric heater (35) for heating a second heat exchange liquid supplied to the heater core (34), and a second reservoir tank (39) into and out of which the second heat exchange liquid flows. On the basis, a partition wall (12) is arranged between the first cooling fan (28) and the electric heater (35), and a first storage box (29) is arranged on the same side of the first cooling fan (28) by taking the partition wall (12) as a boundary, wherein a first heat exchange liquid for cooling the electric motor (15) and the like flows in and out of the first storage box (29) according to temperature change. On the other hand, the second storage box (39) is arranged on the opposite side of the first cooling fan (28) with the partition wall (12) as the boundary.

    本发明的电动式液压挖掘机(1)包括加热用的加热器芯(34)、对向加热器芯(34)供给的第2热交换液进行加热的电加热器(35)以及供第2热交换液流入、流出的第2储存箱(39)。在此基础上,设有分隔第1冷却扇(28)和电加热器(35)之间的隔壁(12)并根据温度变化而供用于冷却电动马达(15)等的第1热交换液流入、流出的第1储存箱(29)以隔壁(12)为界,配置在第1冷却扇(28)的同一侧。另一方面,第2储存箱(39)以隔壁(12)为界,配置在第1冷却扇(28)的相反侧。
